Types of pipe benders for a profile pipe, do-it-yourself manufacturing schemes. Making a pipe bender with your own hands: design options and features of finished products Dimensions of a manual pipe bender for a profile pipe

It happens that you need to bend a metal pipe, but there is nothing to do it. Human strength is not enough to make a bend evenly without damaging the structure itself. To do this, you need a tool - a pipe bender, which is sold in stores and the construction market. But it is possible to make it yourself in the garage with a minimum of equipment.

Even budget versions cost more than homemade ones. And if a homemade pipe bender for shaped pipe you need it for specific work and will not be required anymore - there is no point in buying.

What is a tube bender and where is it needed

Before installing a pipe bender for a profile pipe, you need to learn more about the tool. This is an old equipment used to bend rolled pipes. Why can't it be done with ordinary human power? Metal deforms easily if pressure is applied to it from the sides. The span of human hands is simply not enough to be able to deform the pipe in a specific section of the pipeline.

The do-it-yourself profile pipe bending machine not only bends correctly. It accurately detects the angle of inclination. You can set the parameters depending on your specific needs. This procedure does not require much effort.

The equipment can be made of metal. It is advisable to take steel, as it meets the standard of hardness and strength that we need. Aluminum has a shorter lifespan. But if there are no other materials at hand, it will do. You definitely cannot use plastic, as its strength will not be enough to resist the pressure of the metal.

You can make the equipment for yourself. For the DIYer, several types are available at once, differing in the type of construction. The angle can be fixed during assembly. Usually, in factory models, it corresponds to a range of up to one hundred and eighty degrees.

Views

A bending machine for a profile pipe, even in a garage, can be of several types. You can use materials that are not needed in everyday life.

Structurally, they have the following differences:

Hydraulic

A type of machine that operates on the force of a liquid. It allows bending rolled pipes with a diameter of up to 8 centimeters, therefore it is often found in production. It is rarely used for the home, since we do not need such indicators. But when installing a metal heating pipeline, it will be useful. A hydraulic pipe bender for a thin-walled round pipe is not suitable, since it is characterized by a too coarse deformation method.

Manual

Popular for home use, but cannot be used to bend wide pipes. A simple construction based on elementary physics. Components for assembly are in everyone's garage. Suitable for non-hardened steel, low-carbon ferroalloys, non-ferrous metals (aluminum, copper, various types of their alloys).

Electromechanical

In self-assembly, they are difficult, but they have high performance. They create jewelry precision, they can bend thin-walled tubes without damaging the walls.

Hybrid

They are a combination of electric and hydraulic axes.

Flexion techniques

Additionally, the method of bending itself differs:

Crossbow. For bending, a pre-prepared shape is used, which is suitable for a specific type of pipe. Do-it-yourself crossbow profile bending is a frequent machine in garages.
Spring. The spring mechanism, which provides not only a high-quality bend, in addition, it also does not create destructive deformations.
Segmental. It differs in that the bending occurs with the help of a segment pulling the pipe towards itself.
Rumless. Deformation occurs by winding the profile onto a roller.
Dornovy. The mechanism is similar to the previous one. The main difference is the installation of an additional filler, which prevents corrugation from forming.

Necessary materials

The hydraulic pipe bender for a round pipe has an elementary structure. You can use ready-made drawings that are filled with the Internet. Under They are under any size of the garage. There are many designs, the choice of which is determined by the materials available. If you do not want to go to a hardware store and spend money, look in the bins. Some parts can be ordered from turners and milling machines.

Often, DIYers choose a frontal design that is inexpensive and available for assembly.

It consists of:

Three rollers - metal;
Drive chain;
Axes for rotation;
The movement mechanism that will produce the flexion;
Metal profile to make the frame.

DIYers, in order to save money, install rollers from available materials, such as wood, plastic or polyurethane. The problem here is the cutting theory. The metal is much stronger and denser. Therefore, the roller may not withstand the pressure and crack. No need to save money and install metal ones.

To understand how a pipe bender for a profile pipe does bending with your own hands, you need to understand the technology. Often, conventional types of rolling and rolling are used. They allow you to work even with thin-walled tubes without destroying them and leaving them usable.

To make a bend, the pipe must be installed between the rollers. Next, you need to turn the knob, after which the deformation will be performed according to the specified parameters.

You can make pipe benders for shaped pipes from a jack. If it is in the garage, half of the machine is already ready for you. After assembly, the jack can be removed.

To do this, you will need:

Car jack;
Frame;
Springs (required high-precision);
Three rollers;
Drive chain;
Consumables.

You can watch the video below about how the manual profile bending machine works. To get the result, installed pipe bent with rollers. By scrolling the handle, the drive chain is set in motion, which produces the bend itself.

Pipe bender manufacturing instructions

Making the flexor is easy if you follow these instructions:

Gears, bearings and rings are attached to the pressure shaft, which are connected to each other using a key. Before assembly, you need to draw up a thorough drawing, with the prescribed indicators of all elements. They often have to be ground separately. If you don't know how to use a lathe, trust a lathe. You will need three separate shafts in total. 2. Holes are made in the rings. They will be needed for grooves and threaded connections.
You need to install a shelf. A steel channel is best suited to provide sufficient shaft pressure.
After that, you will need to assemble the entire structure. Use a welding machine whenever possible. Welding joint is the most reliable solution. It does not give in to vibration. If you don't have a welder, you can use bolts. In some places, thick steel perforated plates will be required.
The penultimate stage is the installation of the shelf. A pressure roller is installed on it through a spring. Residual rollers are mounted on the sides. A handle is attached to one of them.
The jack is installed last.

Separate nuances:

The roller is installed on a shelf, to which the spring nut is previously welded;
Tension is required to be done using a magnetic angle, which largely acts as a holder;
The jack is mounted on a hinged platform (if you want to use it separately, use bolted fasteners).

Hydraulic work bender - instruction

The pipe bender for multilayer pipes with hydraulic traction can also be made by yourself. The disadvantage is the complexity of the assembly.

You will need:

Jack with a lifting capacity of at least five tons;
Shoe platform;
Shafts;
Massive channel;
Thick steel sheets and consumables.

To manufacture the device, you need to install a hydraulic jack in the shoe. It is necessary to fix it correctly on both sides. For this, you can use a welding machine or bolts.

After that, the pressure on the jack ensures good bending of the pipe. Having achieved the required angle, it is enough to remove the product and use it for its intended purpose. To make a device, you need to adhere to the following plan:

Make a detailed drawing. In it, you need to describe the dimensions of each individual element. Their production can be ordered from a turner.
The lower platform acts as a platform for the jack. To use it in the future - bolt, not weld.
Rollers are an important part of the design. Its problem is that they are distinguished by strict requirements for accuracy. You can make them yourself. The shoe is mounted below, and the ratio determines the permissible bending angle.

Making a compact snail pipe bender

Products from the profile pipe "Snail" got this name because they act as a force template. This is a stencil that is specifically needed to obtain the correct shape of a flat spiral.

In the process, the tube is pressed tightly against the stencil, forming even spiral shapes. In their design, they resemble machines for seaming glass jars.

A snail is called flat steel plastic (at least four millimeters thick). A stencil part in the form of a spiral is installed on it. The problem is that its production requires at least a milling machine or a good manual frezer... You can't do without a propane cutter. This is a type of burner that allows you to heat the metal and then bend it.

Factory models are equipped with a pin and bolt system. Each part is interchangeable, allowing you to make different bends.

Types of methods

The pipe bender for metal-plastic pipes is an elementary machine that operates on one mechanic. The machine is indispensable for pipelines, including thick-walled and metal-plastic ones. In it you can work with different kinds metal (steel, aluminum, copper, zinc and their alloys). For greater productivity, folds can be pre-reddened to loosen the metal, relieve internal stress and soften it.

Cold method

Common in garage crafts. If there is no blowtorch and torch, you can use it. Of the shortcomings, more effort is required. Cold metal harder, may crack. Therefore, it is only suitable for raw steel and soft non-ferrous metals. Safer in comparison with hot rolled products, since you do not have to work with high temperatures.

Hot method

Requires a torch and blowtorch. Heating removes stress from the metal and therefore it becomes more malleable, but this is only relevant for thin-walled pipe. Thick-walled tubes cannot be heated more than 300 degrees in a garage.

You have learned how to make a pipe bender with your own hands. But it's better to stick to a few additional tips:

To work with different pipe profiles, make removable shafts. To bend thick-walled rolled products, hardened shafts are required. Only the upper layer can be processed.
If the pipe slips when working with the template - install the fixing hooks on the sides.
To bend large-diameter pipes with thick walls, install at least three rollers, which will be enough for comfortable work. It is desirable that they are harder than the material being bent. For this, the surface of the steel roller can be hardened.

When performing various works with pipes, it is often necessary to bend them in a certain shape to solve certain problems. This is done by means of a specialized mechanical unit - a pipe bender. Next, we will look at how to make a manual pipe bender for a round profile pipe with our own hands, photos, videos and drawings will simplify the task and help to avoid mistakes.

One of the types of simple pipe bender

Of course, you can always buy an industrial version. But, such equipment is quite difficult to use, and in terms of cost it cannot be called the most affordable. Therefore, as a rule, it is much more expedient to make a manual pipe bender for a profile pipe with your own hands, drawings and dimensions are present below, so you should not have any difficulties. Various improvised means are useful for manufacturing. Such a tool is quite economical in terms of production and very functional.

So, we make the simplest pipe bender for a profile pipe with our own hands.

As a rule, in domestic or garage conditions, equipment is made of a frontal configuration, structurally consisting of the following components:

3 steel rollers;
chains for the drive;
rotary axes;
a mechanism that activates the components of the finished system;
steel profiles required for the construction of the main structural parts.

Before you start directly making a pipe bender with your own hands for a profile pipe, study the photos, videos, diagrams and drawings. You should be extremely careful about the selection and work (and especially their revision, or adaptation) with drawings, since it is extremely important to achieve high accuracy and correctness of the design from an engineering point of view. You can use drawings from different models of pipe benders. But it is better to take a simpler one, the optimal solution is a front-type machine.

Diagram of the simplest pipe bender

Often, do-it-yourself pipe benders are made with wooden or polyurethane rollers. This decision should be approached carefully, since these materials are not always able to withstand the loads you need. It is necessary to build on the strength properties of the pipe.

To build a pipe bender for a profile at home with your own hands, you need drawings of the model that suits you. Below is one of the varieties of this drawing, which you can use to produce this kind of equipment:

Drawing of one of the bending machine models

To understand how to correctly make a pipe bender with your own hands, watch the video, drawings and a description of the action technology. It is very important to understand the technological side of the process. Typically, such equipment operates on the principle of rolling or rolling, thereby minimizing the likelihood of breakage and damage to the pipe.

The pipe is placed between the shafts of the installation, after which the handle is turned. The technology is extremely simple, but it makes it possible to bend products according to clearly specified parameters and, as a result, get an ideal part for solving the task at hand.

Jack-based bending system

Everything you need to build a pipe bender for a profile pipe with your own hands in garage conditions from available funds - dimensions, drawings and photos are available for download in this material. We also recommend that you watch a video on YouTube about a pipe bender with your own hands, this will allow you to visually see the entire manufacturing process and evaluate possible difficulties in a particular case.

To create this tool, you will need the following components:

simple jack;
profiles and a shelf made of solid steel (the frame will be built from them);
very durable springs;
3 shafts;
chain for the drive;
other components (bolts and other small parts).

Variation of the profile bender on the jack

We make a pipe bender for a professional pipe with our own hands (photos, drawings, pictures)

It is quite simple to build this kind of mechanical system, but it is extremely important to adhere to a clear sequence of actions and accuracy. Everything must strictly comply with the drawings, otherwise the tool will bend the profile incorrectly. To build a pipe bender for a profile pipe with your own hands, you need pictures and drawings, which you can download for free in this material.

The entire production process is divided into several key stages:

Preparing a reliable framework. Bolts and welding should be used to connect the component parts.
Installation of the rotary axis and rollers. One shaft is installed below the other two. The distance between the axes of the shafts determines the bending angle of the pipe. At this stage, it is important to install the elements strictly according to the drawing.
The mechanical part is driven by a chain-type transmission. There should be 3 gears in its design. It is not necessary to use a new chain, you can take the old one from any technique.
A handle is installed on one of the shafts, so that it will be quite easy to rotate with light movements without much effort. The handle is one of the key components of the mechanism for generating the required torque.

How to make a horizontal pipe bender for a profile pipe with your own hands - video and instructions

There is nothing complicated in the procedure for the construction of such equipment, the main thing is to follow simple rules and a drawing.

The manufacturing process involves the following sequence of actions:

Install rings, gears and bearings on the pressure shaft. The connections are made in a key way. Initially, it is necessary to draw all the named elements, then carve them into lathe... The design will have 3 shafts (2 on the sides and 1 suspended by a spring).
Punch holes in the rings to create grooves and threads.
Make a shelf (for the production of this part, a channel is used, preferably strong and massive). In the latter, too, make holes and cut threads to allow the installation of the pressure shaft.
Assemble the components into a single system. Use bolts and a welding machine to connect. First assemble the frame, which also functions as the unit's legs.
Hang the shelf with the pressure roller fixed to it. You will need good springs for this step. Install the support shafts on the sides. On one of the latter, a handle should be installed.
At the final stage, the jack is installed on the equipment.

For a better understanding of the process, see how a homemade pipe bender is made from a jack for a profile pipe with your own hands - video on YouTube:

From the above, we conclude that it is quite simple to make a rolling pipe bender with your own hands from scrap materials.

But, the manufacturing process is characterized by certain subtleties that must be taken into account:

the pressure shaft attached by means of keys must also be screwed to the shelf;
in the process of fixing the pressure shaft, perform the actions in the following sequence: before mounting the shaft to the shelf, it is necessary to weld the nuts to it, for which the springs will cling; upon completion of the installation, you need to turn the shelf over and hang it using springs suitable for the force;
a magnetic angle is perfect for tightening the chain, which acts as a holder;
the sprockets are twisted by means of dowels (for the manufacture of the latter, use a grover);
provide a scrolling tube on the handle of the drive, so it will be much more convenient and easier to work;
the installation of the jack should be carried out on a suspended platform (to complete all connections, we again use ordinary bolts or a welding machine where necessary).

Making a hydraulic pipe bender for a profile pipe with your own hands (drawings and video)

This page contains all the information you need, after studying which you can build the simplest pipe bender with a jack with your own hands (drawings, photos, videos and instructions). Many craftsmen, especially professional ones, construct a hydraulically driven machine as this increases functionality. But, to manufacture such equipment is somewhat more difficult, in comparison with the option considered above. This is a rather laborious process. Therefore, we recommend that you watch a video that shows in detail the manufacturing process of this device.

How to assemble a universal pipe bender with your own hands - watch the video:

Based on the design and drawing of this unit, we select the components included in its design:

hydraulic jack (must be designed for loads weighing from 5 tons);
shoe;
2-3 rollers;
durable steel channel;
thick steel plates and other elements.

To achieve the required bending parameters of the product on a similar home-made machine, it should be placed in the shoe, fastened on both sides. Then a jack is applied, the lifting rod of which exerts pressure on the shaft. The latter, in turn, directly acts on the fixed product, gradually performing the required bending. When the pipe is bent according to the preset specifications, it can be dismantled. To do this, it is enough to turn the jack mechanism back a little to relax the entire system.

Technological aspects of the bending process

By following simple tips, you will avoid problems and mistakes during the bending process. Hydraulic units make it possible to bend a professional pipe made of almost any material, including those with walls of rather considerable thickness. There are hot and cold ways to bend products.

A kind of device with a jack

The easiest way is to use the cold bending method. This technology is suitable for plastic products. The peculiarity is that the professional pipe must first be filled with sand, salt, oil or cold water. Due to this, it is possible to significantly improve the quality of bending, eliminating damage to the product.

If you plan to bend a thick-walled pipe, you should use the hot method.

Various shafts for different types pipes

In a manual machine, the absence of sprockets is allowed. The device can be built on a single drive roller. The clamping screw can be replaced with a jack.
Use steel hooks to prevent slipping of the pipe during template bending.
If it is necessary to achieve a large bending radius, it is worth using a machine equipped with 3 rollers.
To achieve the versatility of the device, it is worth ensuring the mobility of the thrust rollers. This will allow you to adjust the radius.

Watch the following video to understand how a budget DIY profile pipe bender (YouTube) works:

For maximum bending accuracy, it is recommended to use a special template. It is easy to make from wood. This solution allows you to achieve perfect accuracy even on the simplest home-made machine.

To work with pipes or a corner, a special machine is required, called a pipe bender. This design allows you to bend metal elements at a given angle. If necessary, you can make a professional pipe bender with your own hands, which is used in a wide variety of industries. Unlike the industrial version, a homemade pipe bender is much cheaper. When carrying out the work, you can use materials at hand, which will reduce the cost of the structure to a greater extent. Let's take a closer look at how to make a pipe bender with your own hands at home.

Pipe bender device

There is simply great amount different types of the device in question. Before carrying out work on its creation with your own hands, you should develop a drawing of a pipe bender or download it on the Internet.

You can make a pipe bender for a round pipe with your own hands, taking into account the following features of its device:

Running in. Such a pipe bending machine is characterized by the fact that one end of the workpiece is fixed, and a fixed template is used for bending. Running in is carried out using pressure rollers. This manual pipe bender scheme has been used for many years.
Winding. A special pipe bender for aluminum pipes is characterized by the fact that the workpiece is pressed against a movable template, which is used as a roller. The broaching is carried out between the roller in motion and a special stop. As a rule, the drive is electric, since the required indicator of the applied force is quite high.
Crossbow construction. This scheme is represented by a combination of two fixed rollers and a movable template. The force is transmitted to the workpiece through a movable template, which is located between two rollers. By controlling the movement of the movable element, the most suitable bending angle is selected. It should be borne in mind that the punch of the pipe bender, which acts as a template, can have a different shape.
Rolling or rolling. In this case, the circuit is represented by a device with three rollers, two of which are supporting and one is movable. The bending radius is adjusted by changing the position of the central roller. It should be borne in mind that such a device is considered universal, since the bending radius can be adjusted in a fairly wide range. The dimensions of this type of pipe bender are relatively small; a home-made design can be compact.

Choosing the most suitable design for homemade, it should be borne in mind that the version operating on the knurling principle is often produced in an industrial way due to the complexity of the high complexity of the main mechanisms. The crossbow bending method is used extremely rarely today, since it has one significant drawback: the pressure is concentrated on the upper part of the template. When using a crossbow machine, there is a possibility of a significant reduction in the thickness of the pipe wall, as well as its rupture. It is not recommended to use such a device for bending thin-walled workpieces.

The most widespread design is that it works on the rolling principle. It is practically devoid of all the above disadvantages, has a relatively small size, can be portable, it is possible to adjust the bending angle.

A homemade machine can have a wide variety of designs. When choosing a type, attention is paid to what radius should be obtained. The most important parameters of the workpiece that can influence the choice of a suitable design are the wall thickness of the pipe and its diameter.

Types of pipe benders

The design in question can be classified according to a fairly large number of features. On sale there are universal versions, as well as for narrowly targeted applications. The device differs in the following ways:

By drive type. An important design element can be called a drive, which can be hydraulic, electric, manual or electro-hydraulic. Recently, the electric drive has become more common, since it is compact and very efficient. Hydraulic is more efficient, but difficult to operate, takes up a lot of free space and requires periodic maintenance. The manual pipe bender is distinguished by the presence of a mechanism that significantly increases the applied force. If we consider homemade options for execution, then they make a manual pipe bender with their own hands. In addition, you can create a pipe bender with an electric drive with your own hands. But the hydraulic version is practically impossible to make on your own.
The classification is carried out according to the degree of mobility. There are stationary and portable design options. In most cases, the universal hand tube bender is made as a portable design. A homemade pipe bender for a round pipe can be attached to the base in various ways. It should be borne in mind that during the execution of the work, part of the resulting voltage is diverted precisely to the base. Therefore, when creating homemade version execution, it is necessary to ensure reliable fixation of the device.
By the method of influencing the workpiece - the main feature of the classification. For example, a crossbow-type pipe bender has its own special design, which is suitable for bending metal or metal-plastic pipes. In addition, a structure is distinguished that works on the principle of rolling, winding or rolling.

A homemade pipe bender for metal-plastic pipes can be of various types, but most often they create a mechanical type, when, due to a special design, the transmitted force increases several times.

Pipe bender manufacturing instructions

Recently, the question of how to make a pipe bender with your own hands has become quite widespread. Such equipment is required when setting up production activities of the most varied types. The most simple do-it-yourself pipe bender has a template type of design. This is due to the fact that it is quite difficult to make rollers for a pipe bender with your own hands.

Considering the template pipe benders for a round pipe, we note the following points:

In the manufacture of a structure, solid wood is often used. This greatly simplifies the work and reduces costs. However, it should be borne in mind that the low strength and rigidity of wood determines the use of such a machine only for bending aluminum, which has high ductility.
The used wooden block should have dimensions that are larger than the diameter of the workpiece being processed.
The template must have a radius that matches the bend radius. In order to simplify the process, a small groove is created in the central part of the surface that is in contact with the workpiece.
For the convenience of work, two handles are created, which have a metal mount.
Having created a pipe bender at home, it should be attached to a solid base, and a stop should be installed on the back side.

An important point is that the considered design is applicable to a greater extent for bending over a large diameter. In addition, a shoe for a pipe bender of this type is not required, the load is evenly distributed, which allows processing thin-walled workpieces.

You can make a pipe bender with your own hands according to other drawings. Before choosing the most suitable design, you should consider how often the work will be carried out, for what kind of workpieces the machine is made, how much production will be. The design of the template type is characterized by a rather large size, however, for its manufacture it is enough to carry out carpentry work, the materials used are of low cost.

The most complex design is considered to be a self-made roller-type pipe bender. In this case, a pressure roller is used to transfer the force. In the manufacture of a structure, it can use metal and wood, it all depends on how mobile it should be and for what effort it is designed.

The features of this design include the following points:

For pipes made of soft materials, wood is more suitable as the main material. It can be used to make a roller. For steel pipes, metal will have to be used, since the magnitude of the transmitted force will be significant. If desired, the videos can be purchased or made by hand at home.
The design features determine the presence of a movable and fixed roller. In this case, a U-shaped holder is located in the central part.
The bending radius largely depends on the size of the rollers used. This is why the movable roller must, if necessary, be quickly dismantled in order to install a version with a different diameter.
The holder to be installed must also be able to rotate.
A handle is attached to the installed holder, when rotated, force will be transmitted. It should be borne in mind that the handle acts as a lever. That is why the amount of effort that can be transmitted depends on its length.

Such a machine is suitable for production in large batches, since it is rather difficult to make rollers for pipe benders with your own hands. The device is suitable for working with circular pipes.

A common question can be called how problematic is the manufacture of such a mechanism. When using a bending machine of this type, the following points should be considered:

To begin with, you should study in detail the drawing or photographs of the equipment in question. Only by understanding the principle of its operation can you create effective equipment with a wide range of applications.
The main elements of this design are relatively small. An example is two pulleys, which can be made of wood or steel, a frame with a lever, and a pinch roller. It is quite important to create a solid foundation that will take some of the effort.

The principle of operation is quite simple:

The workpiece is placed in the stationary roller chute.
The pipe is fixed in the desired position with a clamp.
With the help of a lever, the workpiece is wrapped around the template, which is also used as a roller of a certain diameter.

In order to significantly increase the efficiency of the structure, an electric drive can be used. However, it should be borne in mind that with an electric drive it is rather difficult to control the curvature diameter indicator. In addition, the installed electric motor must transmit rotation through the step-down drive, since the rotation speed of the roller is low. For this, a gearbox or V-belt transmission is installed.

Crossbow pipe benders

The crossbow machine has a rather unusual design. It got its name from its similarities to medieval weapons. The crossbow pipe bender has the following features:

The basis of the structure is represented by a frame, which can be made using corners and channel bars. The connection of all elements is carried out using welding; split methods are not recommended to be used, since the resulting structure must have high rigidity.
After creating the frame, the two rollers are fastened.
A homemade version can be characterized by the fact that the force is transmitted directly through a mechanical type jack. For a pipe with a small diameter, the generated pressure should be sufficient. Power transmission is carried out through a shoe made of strong metal with a low ductility index.

The crossbow type pipe bender is more suitable for round workpieces. This is due to the fact that a product with a different cross-section can deform strongly under pressure.

Hydraulic pipe bender

When making a pipe bending machine with your own hands, you should decide on what kind of drive will be. In most cases, self-made versions have a manual drive, since it is easy to manufacture and is cheap. However, this design cannot work with workpieces that are manufactured using hard metals. The hydraulic pipe bender allows you to work with workpieces of large diameter and with a significant wall thickness, however, the design is quite complex in execution and has many features.

When making a machine for a round pipe with a hydraulic drive, the following points should be considered:

The transfer of force is carried out through the working fluid, which is used as oil or water. All lines must have a high degree of tightness, and also be designed for a certain pressure.
A compressor can be used to generate pressure.
The pressure is transmitted to the working body through the hydraulic cylinder.

A do-it-yourself pipe bender for metal-plastic pipes with a hydraulic drive can have a wide variety of designs. An important element in this case is the drive, which allows you to automate the bending process and increase the scope of the device.

Pipe bender from a jack

Most often, when making a homemade pipe bender, a jack is used as the main element. It comes in several types. The jack itself was originally made in order to increase and concentrate the applied force, due to which the structure can lift heavy mechanisms, for example, cars.

A homemade pipe bender from a jack, as a rule, has a rather simple design:

The workpiece is clamped between two stationary rollers.
The force is transmitted to the gap between the rollers.
The distance between the fixed rollers largely determines the bending radius and the amount of force required to obtain a certain angle.

As previously noted, when using a jack, you can make a crossbow-type pipe bender.

In conclusion, we note that almost any device is a relatively simple machine, which, due to the distribution of the applied force, bend pipes and other workpieces of a similar type. They are often used for bending products made using non-ferrous alloys and steel. The industrial version of the design bypasses the self-made, as a rule, in the degree of process automation. However, the cost of industrial pipe benders can exceed the costs associated with the production of a homemade version by several tens of times. That is why a homemade pipe bender is more suitable for domestic use or small-scale production.

The pipe bender is a very useful tool in the household if you are used to doing everything with your own hands. Sheds, greenhouses and canopies are made of a bent profile pipe, giving the water pipes the desired bend. Using this tool, it will not be difficult to make all kinds of products that have a variable radius. You can save on buying a tool and make it from drawings and photographs yourself. A master class from the video will show all the subtleties of the process.

On the construction market, you can purchase various modifications of professional pipe benders. For bending small diameter pipes, a hand-operated tool is suitable; large diameter pipes are bent with a tool equipped with a hydraulic drive. Industrial units are stationary and portable. An easy-to-use tool that is connected to the mains. Pipe benders are classified according to the bending method:

crossbow-type pipe benders use a template of the required diameter as a bending unit;

Crossbow pipe bender

manual drive bends pipes using springs;
segmented pipe benders bend pipes in a segment. They are most often used by plumbers;

Manual pipe bender

mandrel mechanisms are designed for bending thin-walled pipes to a small radius.

Advice. In special reference books, you can find tables with permissible values of the bend radius depending on the thickness and diameter of the pipe. Violation of the radius will create zones with increased metal stress, which will significantly reduce the quality and strength of the pipe.

This mechanism is suitable for small diameter pipes. The template is made from boards that are thicker than the pipe diameter. The edge of the template is cut at an angle to prevent the pipe from slipping out. The boards are fastened together and fixed on the table surface. A stop is attached at a certain distance from the template. The pipe is inserted between the stop and the template and bent. The pipe cannot be bent from the center of the template - it will break. And if it does not break, then the appearance will not stand up to any criticism.

Tube bender from template

In a similar way, a pipe bender is made from a concrete slab and durable metal pins. Holes are drilled in concrete and pins are driven in at a distance of no more than 5 cm, pins are driven in at the edges. To fix the curved pipe, a jumper can be welded to its ends, which is then dismantled.

A similar pattern can be made from a sheet of plywood and hooks. By changing the location of the hooks, you can change the bending radius of the workpiece.

Roller manual pipe bender

In the manufacture of such a mechanism, the main difficulty lies in the selection of rollers and the desired template. The bend will not work well if the rollers do not wrap around the pipe. For bending flexible pipes, the rollers can be cut from hardwood blanks. The rollers can be made on a lathe or with a jigsaw.

Rollers for a homemade pipe bender can be turned on a lathe

Wooden circles are cut out at the required slope, then assembled into one piece, sanded with sandpaper. To give strength to wooden parts, they are reinforced with metal plates. To bend pipes along a large radius, you will need a pipe bender with three rollers.

Pipe bending machine

A manual rolling machine will be a good help in the workshop of a home craftsman. For its manufacture, you will need such materials that can be bought at a pleasant price at metal collection points.

The distance between the shafts matters. The further the shafts are located, the less force the operator will need to apply to drive the pipe, the minimum radius value increases and the distance of the pipe section that will not be processed increases, respectively, the stroke of the pressure shaft will be longer. Therefore, at the design stage of the drawing, it is necessary to calculate several options for the position of the side shafts.

Finished rolling machine

If rollers are used instead of shafts, limiters (steel corner) must be placed on the sides, which will hold the pipe in a strictly vertical position and perpendicular to the axis of the rollers. Otherwise, the profile tube will bend in a spiral. After the final assembly, the fixture can be painted for aesthetic pleasure.

The given device can be improved if desired. Add a motor with a geared motor to the tool, which will set the shaft in motion by rotating the chain drive. Installing a jack instead of the upper shaft will allow bending pipes of different diameters. The jack regulates the pressure and sets the height. Such an upgrade will allow you to bend pipes on an industrial scale for a small enterprise, under all sorts of radii.

Scheme: pipe bender using a jack

It is convenient to work with a partner on such a machine: one person turns the winch, and the second pulls the pipe. The pipe blank is placed on rollers and pressed down with a jack. The winch pulls the pipe along the shafts, then add the jack force and run the workpiece again. The cycle is repeated until the pipe acquires the desired bend.

Advice. When bending the profile pipe, sand poured into the profile will protect it from destructive deformations.
The device, once independently made, will serve for a very long time, and will be in no way inferior in quality to the purchased equipment. If the pipe bender is needed for one-time use, then it is more expedient to rent the device.

DIY pipe bender: video

Bending of profile pipes is a fairly common procedure, for which a special device is used - a pipe bender. You can make a pipe bender for a profile pipe with your own hands, or you can purchase it at the construction market or in a store.

One of the simplest types of pipe bender for profiled pipes

Serial devices differ in their principle of operation, they may have different types drives, however, some experience is required to operate any of these attachments. Limits the use of devices manufactured in a production environment, and the fact that they are expensive. A good way out in all such situations will be the independent manufacture of a device designed for bending shaped pipes, for which you can use available tools.

Required structural elements

The circuit of the pipe bender is very straightforward.

To make a pipe bender with your own hands, you can use drawings of various designs. Their choice is mainly determined by what materials you have. Most often, they opt for front-type pipe benders, the design of which includes:

three rollers (shafts), which must be metal;
drive chain;
axis of rotation;
a mechanism that will set in motion all the elements of the device;
metal profiles from which the frame of the device will be made.

Very often, a machine for bending a profile pipe is made with rollers, which are made of wood or polyurethane. When choosing such materials, one should take into account the strength characteristics of the pipes that will be subjected to bending. If you neglect this requirement, then the working elements of a home-made device may simply not withstand the load and collapse.

Pipe bender drawing: sectional view of the pressure roller mounting structure

In order to understand how to bend a profile pipe on a homemade device, it is important to understand the technology used for such a process. As a rule, pipe benders use the principle of rolling or rolling, which minimizes the risk of breakage and damage to the pipe.

To make a bend on a profile pipe using such a device, it must be inserted between the rollers of the pipe bender and turn the handle. The use of such a simple bending device makes it possible to obtain bends on the profile pipe that fully correspond to the specified parameters.

Pipe bender using a jack

To make a simple machine for performing bending of shaped pipes, you will need the following structural elements:

ordinary jack;
metal profiles and a shelf required for the manufacture of the frame;
high strength springs;
shafts in the amount of 3 pieces;
drive chain;
a number of other structural elements.

When using such a device, the operation of which can be seen in one of the videos below, the pipe is laid on two side rollers, and a third is lowered onto it from above, creating the required force. To give the pipe the necessary bend, turn the handle that drives the chain and, accordingly, the shafts of the equipment.

Inverted Jack Option

Pipe bender manufacturing process

To make a device for obtaining a bend of shaped pipes, you must perform the following procedures.

Prepare a reliable frame, the elements of which are connected by welding and bolted connections.
According to a previously prepared drawing, set the axis of rotation and the shafts themselves, two of which are located above the third. The bending radius of the profile pipe depends on the distance at which the axes of such shafts are located.
To operate such a bending mechanism, a chain drive is used. To complete such a transmission, it is equipped with three gears, and the chain itself can be picked up from an old car, motorcycle or other equipment.
To operate such equipment, a handle is needed, which is connected to one of the shafts. It is due to such a handle that the required torque is created.

Pipe bender manufacturing instructions

It is not difficult to make a pipe bender for a profile pipe on your own if you adhere to the following technological sequence.

Gears, bearings and rings are placed on the pressure shaft, which are connected to it with a key. First, a drawing of such a shaft, a cage for bearings and rollers is developed, then these parts are turned, which is best entrusted to a qualified turner. In total, for this device, it is necessary to make three shafts, one of which is suspended by springs, and the other two are located on the sides.
Then, holes must be drilled in the rings, which are necessary for making grooves and threading.
Now you need to make a shelf, for which a channel is used, in which holes are also drilled and threads are required when installing the pressure shaft.
After completing the preparatory measures, the entire structure of the equipment must be assembled, for which welding and bolted connections are used. First of all, the installation of the frame is performed, which simultaneously serves as the legs of the pipe bender.
The next step is to suspend the shelf with the pressure shaft attached to it, for which springs are used. After that, it is necessary to install side support shafts on a homemade pipe bender, on one of which a handle is attached.
The final touch is to install the jack on the pipe bender.

Some subtleties of execution installation works:

the pressure shaft, fixed with dowels, is additionally screwed to the shelf;
the installation of the pressure shaft is carried out according to the following scheme: the shaft is installed on a shelf to which the nuts for the springs are pre-welded, after the installation work is completed, the shelf is turned over and suspended on the springs;
the chains are tensioned using a magnetic angle, which is used as a holder;
when tightening the sprockets, dowels are used, which are pre-made from a grower;
the drive handle for the bending machine is made with a rotatable tube;
a jack for such a homemade device is installed on a suspended platform, for which bolted joints and welding are used.

Hydraulic pipe bender manufacturing

On the Internet, you can find many photos and videos on how to independently make a device for bending shaped pipes with a hydraulic drive. The manufacturing process of such a pipe bender, equipped with a hydraulic cylinder, a pressure device and pipe stops, is a rather laborious undertaking.

In the drawing and in the design of such a pipe bender, the following elements can be distinguished:

hydraulic jack with a lifting capacity of at least 5 tons;
shoe;
rollers in the amount of 2-3 pieces;
powerful metal channel;
thick metal plates and other details.

To perform the required bending of the profile pipe using a hydraulic device, it is necessary to insert it into the shoe and fix both its ends. After that, you need to use a jack, which, with its rising rod, presses on the roller, which acts on the pipe and bends it. After the required bend angle is obtained, the process can be stopped and the pipe can be removed from the pipe bender by turning the jack handle several times in the opposite direction.

Prefabricated and painted tube bender for shaped pipes

In order to independently make a hydraulic bending device for profile pipes, a photo of which can be found on the Internet without any problems, you must perform the following procedures.

According to a drawing or a photo, a structure is made for mounting a shoe and rollers, as well as an equipment frame.
A metal plate is attached to the lower platform, on which the jack will be installed. After that, such a device is fixed with bolts and a drive handle is installed on it.
The most important thing is to find suitable rollers for the profile tube, which should be tightly wrapped around their working part. If desired, rollers for a profile pipe, which are installed on the channel at the same height, can be made by hand. The shoe is installed below the rollers, and their relative position is determined by the required bending radius.
To fix the rollers and shoe, bolts are used, the holes for which are made according to the dimensions indicated in the drawing.

Pipe bending methods using a homemade machine

The question of how to bend a profile pipe using a homemade pipe bender is unlikely to confuse you if you read a few more recommendations. On hydraulic machines, it is possible to successfully bend profile pipes from different materials, as well as thick-walled products. This operation can be performed both by cold and hot methods, which presuppose the preheating of the pipe section.

Thus, a manual hydraulic bending machine can be used to act on a pipe in two ways:

Another variation with a jack

Cold bending is the simplest bending method used for pipes made of plastic materials. The subtlety of this process is filling the pipe before the flexible with sand, salt, oil or cold water. This allows you to get a better bend without significant deformation of the pipe.

If you are interested in the question of how to properly bend a profile pipe with thick walls or made of materials of increased rigidity, then the use of the hot bending method will be the answer to it.

To the question of how to bend a profile pipe as accurately as possible and without unnecessary labor, several answers will be given useful tips from qualified professionals.

Removable rollers of various shapes will allow you to comfortably work not only with profile pipes, but also with round ones.

In manual pipe benders for bending profile pipes, you can not use sprockets, but assemble a structure based on one drive roller. Instead of a clamping screw, a jack is often used in such pipe benders.
If you are bending according to a template, then so that the pipe does not slide off it, you can use metal hooks as stops.
If it is necessary to bend a profile pipe under a large radius, it is best to use a pipe bender with three rollers.
To get a more versatile bending machine, you can make its thrust rollers moveable. This will allow you to change the bend radius of the pipe.

In order to strictly adhere to the dimensions of the required pipe bend, it is best to perform this operation using a template that is made of wood. Even the simplest manual pipe bender using such a template will allow you to bend a profile pipe with exact observance of the specified parameters. By the way, such templates are mainly made for the implementation of the simplest manual bending methods.

Homemade pipe bender for a profile pipe: device and manufacturing nuances

The need for a reliable and simple device for bending shaped pipes arises when a home craftsman begins to seriously deal with metal. Gazebo frame, carport, garden bench, workbench ...

These and many other structures are durable and beautiful if the profile metal for them is carefully bent on a special profile bending machine.

There is always an economical alternative to buying a finished machine tool, since you can make a pipe bender for a profile pipe with your own hands in your home workshop. Before the first workpiece is clamped in a vice, we invite you to get acquainted with the principle of operation and the existing varieties of homemade pipe benders.

How does a pipe bender work?

The principle of operation of this device is simple: a profile pipe is placed between three support shafts. The center shaft creates pressure that bends the metal to the desired angle.

A point machine is used to bend the pipe in one local section.

If you need to get an arched profile, then a rolling bending machine is used that combines the bend of the metal with a broach.

Varieties of pipe benders

Depending on the drive that transfers the force to the profile metal, there are three types of pipe benders:

mechanical (pressure is created manually using a central screw or lever);
hydraulic (using a hydraulic jack);
electric (the bending force is created by an electric motor);
electro-hydraulic (the hydraulic cylinder is driven by an electric motor).

It should be noted that the rolling pipe bender with manual profile broaching is designed for a small section pipe (maximum 40x40 mm). A large profile cannot be pulled manually. For its bending, powerful machines with an electric broaching mechanism are used.

How to make a do-it-yourself bending machine?

The main principle that should be followed when developing a drawing of a homemade pipe bender is maximum design simplicity and reliability.

The machine for point bending can be assembled from two pieces of channel, four corners and two pieces of fingers from tractor tracks.

Bending of the pipe in it is performed by a standard hydraulic jack with a force of at least 5 tons. A steel "shoe" is installed on its working rod. You can order it from a turner or make it yourself from an old pulley, the width of which is equal to the width of the profile pipe. By cutting off a half from the pulley and drilling a seat for the jack rod in it, a hydraulic drive mechanism is obtained.

The bed of the homemade device consists of four corners (shelf 60-80 mm) welded to a steel plate. Two channels are welded to the upper ends of the corners in parallel. In their walls, holes are symmetrically drilled to adjust the bend angle of the workpiece.

In working position manual machine for bending a profile pipe it is very simple:

Two steel fingers are inserted into the holes on the channel and the stop rollers are placed on them.
The jack with a shoe is raised so that a profile pipe passes between it and the stops.
Having installed the pipe, they work with the jack handle, creating a bending force.

A rolling manual pipe bender for a profile pipe is also quite realistic to build on your own. To make it, you will need 2 running meters of a channel (wall height 15-20 cm), from which the base and racks are cut.

Six short pieces of steel pipe are taken to make the rollers. It will act as a bearing cage. Therefore, its inner diameter must be equal to the outer diameter of the bearing. Having ordered three shafts from the turner for fitting the bending rollers, they start welding the bed.

In the machine under consideration, the extreme right support plays the role of a guide that sets the profile bending angle. It is mounted on a channel pivotally connected to the main bed using conventional door hinges... The jack with the working rod rests against the turntable and raises it.

By rotating the handle mounted on the intermediate stop shaft, the profile is pulled through the machine.

You can adjust the profile bending radius not only by tilting the swivel channel, but also by the extreme rollers. To do this, they are not tightly welded to the bed, but made movable (holes are drilled in the channel and base plates).

Instead of a hydraulic jack, a screw car can be used to raise the outer drum.

How to make a profile bender with your own hands

When arranging a site or in preparation for the summer cottage and garden season, there is a need for arcs from a profile pipe. They are needed when arranging a greenhouse, assembling a gazebo or a shed. It is unprofitable to buy already bent arcs - the price is twice as high as for the same flat rolling. The way out is to do it yourself, and in order to facilitate the process (it is very difficult with your hands) you need to make a pipe bender for a profile pipe. You will need channels or angles, rolling rollers and some more details. Of the tools - a grinder with a disc for metal, a welding machine, a ruler.

Profile bender design

The machine for bending a profile pipe is structurally different from the usual one. This is due, firstly, to the greater resistance of the profile to bending loads, and secondly, to the fact that the bending radius is usually required to be large. Therefore, there are three rollers in the design. Two of them are permanently installed, one remains mobile. With the help of a movable roller, the radius of curvature is also changed. In general, there are two types of pipe bender for a profile pipe: with a middle movable roller and with an extreme one (right or left - at will).

A pipe bender for a profile pipe with your own hands can be made in different sizes

Pipe bender device with middle movable roller

The two outer rollers are fixed to the body. They are raised above the plane of the base. For the middle roller, a special U-shaped frame is cooked. A long, large-diameter clamping screw is installed in the middle of its lintel. A third roller is attached to the lower end of this screw (can be welded). By turning this screw, the roller rises and falls, changing the bending radius of the profile pipe.

The design of a pipe bender for a profile pipe with a movable middle roller

A cloud is welded to one of the fixed rollers, with the help of which the pipe is rolled through the machine. So that less forces can be applied for rolling, the two stationary rollers are connected by a chain. For effective transmission of torque, sprockets are welded to the rollers (you can from a bicycle), a chain is selected to them. Such a simple mechanism makes the bending of a profile pipe much easier.

With extreme movable roller

In this design, the right or left roller is made movable. It moves with part of the base. This part is connected to the rest of the bed using heavy-duty metal hinges.

Drawing of a profile pipe bending machine with a lifting platform

You can change the height using a jack, as shown in the drawing. The platform height in this case is selected depending on the height of the jack. The bending radius is changed by lifting the movable part of the table.

Profile tube bender with lifting platform

Unlike the previous design, this profile pipe bender is driven from a central roller - a handle is welded to it. To reduce the required force, you can also weld the sprocket to two stationary rollers and transmit the torque using a chain.

What materials and design nuances are needed

The base of the pipe bender is made from a channel or two welded corners. The thickness of the shelves is at least 3 mm, the width of the shelves and the back of the channel should be matched to the available parts. One rule is that the foundation must be solid and reliable.

Several holes can be made around the edges of the platform. Through them, you can fix the machine to some heavy base using large-diameter self-tapping screws. Fixation is necessary, since when bending pipes with a thick wall, the forces have to be made significant and it is more convenient to work if the machine is firmly fixed.

This is how the bed looks like in welded uprights for fixing a movable roller

A few words about rollers. They should be made of good quality, preferably hardened steel. It is the rollers and the axles that hold them that bear most of the load.

I must also say about the shape of the videos. They should not be smooth - there should be rollers along the edges that will not allow the pipe to "walk" during rolling. Only under such conditions will the arc from the profile pipe be flat, and not twisted. Ideally, each pipe size needs its own rollers. But then the design becomes more complicated - they must be made removable, thought over reliable way fastening. The second option is to make videos of complex shapes, such as in the photo. Carve a few steps under different sizes pipes.

Rollers for bending profile pipes of different widths

The same photo shows that the top of the bed is uneven and jagged. With the help of such teeth, the rollers can be rearranged at different distances and thus also the bending radius can be adjusted.

In general, self-made bending machines for shaped pipes are assembled from what is at hand or what they find / buy inexpensively. Whoever has the opportunity - grinds the rollers, inserts the bearings. Those who do not have this opportunity use what they have - right down to the hubs from bicycle wheels. In general, you need to understand the design and

Tricks to make pipe bending easier

To make the rollers move better, bearings are used. But, in principle, for a homemade pipe bender, which will be used only from time to time, you can simply make holders from a corner or channel. Make a hole in them, which is slightly larger than the axis on which the roller will be mounted. Pass this axis with the roller on through the holes of the holders and somehow fix them (at least weld on a couple of points that will be stoppers). During operation, for a better stroke, lubricate rubbing places with a grease such as Litola. For industrial and semi-industrial production, this is not suitable, but for making arcs for a greenhouse or a gazebo with your own hands - just right.

An example of turned rolls

There is one more trick that helps to reduce the required force when bending a profile pipe. You can use the principle of increasing the gear as in a bicycle. By the way, you can use bicycle sprockets. In this case, the handle that drives the rollers is welded to a small sprocket. It is installed somewhere on the body. Sprockets are welded on the axis of the shafts bigger size(but teeth with the same pitch). All this is connected by a suitable chain.

With such a torque transmission device, an electric drive is not needed - it will be easy to work

And one more improvement - with the constant use of a pipe bender for a profile pipe, it makes sense to mechanize it. In this case, they put a motor that runs at low speeds.

The procedure for bending a profile pipe on homemade machines

You will hardly be able to get the required bending radius at one time - too much effort is required for this. It is unrealistic to create it manually. The required bend is obtained in several passes:

First, the rollers are set so as to obtain a slight bend, the pipe is rolled in one direction, then removed from the rolls, unrolled and inserted on the other side. It is necessary to unfold in order to get an evenly curved pipe.
With the same position of the rollers, it is pulled several times, until the curvature is no longer added.
If the required bend radius is not reached, change the position of the roller and repeat the steps again.

Rolling pipe bender with electric drive

The change in the bend radius is obtained gradually, otherwise you cannot make an arc from a profile pipe on a homemade pipe bender. What if you need to repeat the same bend? Make a graduation - note the height to which the roller moved, how many times it was rolled in each position. When repeating, the differences, if any, will be insignificant.

The difficulty in bending lies in the fact that there is no scale and it is difficult to obtain the intended bending radius without experience. You will get it sooner or later, but you can spoil a lot of material.

How to bend a profile pipe without a machine

You can get an arc from a profile pipe without a profile bending in two ways - using welding and a template. Let's start with welding.

Get an arc by welding

The profile pipe is cut with a grinder on one side. They are made every 15-30 cm, depending on the required radius, section and wall thickness. The cuts should not touch one side - the one that will be on the outside.

Bending result by welding

The spare part prepared in this way is bent, giving the desired bend. For reliability, the edges of the arc can be fixed by welding a rod to them. Then they are welded along all the cuts, welding them. And the last stage is the grinding of the welding places and treatment with anti-corrosion compounds.

Using a template

Thin-walled profiled pipes can be manually bent using templates. If you need some special shape, you can cut it out of a piece of thick plywood or chipboard, and fix it on the table with clamps. On the workbench, where we will bend the pipes, they make 8-10 holes. The template is positioned near these holes.

The process of obtaining an arc from a profile pipe using a template

At one end of the pipe, the holes are repeated, with their help, the pipe is attached to the workbench. Now the free end of the pipe begins to pull smoothly, forming a bend that repeats the shape. It is necessary to pull smoothly, without jerking.

The template can also be made on the ground. Peg pipes are hammered into the ground (at least half a meter deep). They form the required arc. For an emphasis, two additional stakes are hammered, which are located to the side of the arc. The distance you need to step aside is slightly more than the width of the pipe.

Pattern on the ground

After inserting the pipe, it is pulled towards the arc. Great efforts are needed, the work is hard. It can only work with a thin-walled seamless pipe. The seam has too much resistance in the seam area. It is very difficult to overcome it manually.

Diy pipe bender for a profile pipe

DIYers often use a profile pipe. You can expand your creative possibilities with the help of a pipe bender, which you can do with your own hands.

How to make a pipe bender for a profile pipe with your own hands

If you like to create unique building structures, engineering structures, good equipment of a home workshop will come in handy. When selecting specific types of equipment, you need to pay attention to the mechanisms discussed in this article. To make a pipe bender for a profile pipe with your own hands - study the detailed instructions, videos, photos, drawings. With the help of these materials, it is not difficult to implement the corresponding project.

Diy pipe bender for a profile pipe: basic data

Before studying the working documentation and algorithms for installation operations, you should accurately determine the intended purpose of the product. A pipe bender for a profile pipe with your own hands should be designed for certain efforts, dimensions of workpieces, materials. It is easier to establish meaningful criteria after familiarization with the parameters of devices tested in practice.

What are these devices for?

Elements of building structures of complex shapes are created using different techniques:

Fastening with bolts and screws may not always provide the required reliability. Such joints are destroyed by vibration, additional loads are formed.
Welding has an excessive heat effect that disturbs the original structure of the materials. In order for the connection to be reliable and durable, a good qualification of the work performer is required. Special equipment consumes a lot of electricity. In some technological processes, expensive consumables are used, and special conditions are created.
Adhesive joints are limited resistance to loads and influences of a different nature.

The above disadvantages are eliminated in whole or in part if the workpiece is bent in the right way. To avoid damage, precise dosing of loads and speed is required. In some places, it is necessary to maintain the integrity of the walls with external supports.

To reproduce such techniques without errors, use special devices, machines

What engineering solutions will be applied in practice

With a relatively low strength of materials, it will be enough to use a suitable stencil.

The workpiece is wound on a roller, forming the required angle

To create necessary effort, the linkage is installed here. A metal pin is used to fix the free section of the pipe. It is installed in the appropriate grooves of the “comb” before performing any work steps.

"Crossbow" type machine

Using this factory sample as an example, it is easier to study the design features:

The handle (1) is used to adjust the automatic piston stroke in the opposite direction. This solution reduces the burden on the user.
A hydraulic system is installed inside the housing. When the handle is moved up and down, a force of up to 150 kN is transmitted to the working piston (8). This is enough for fast bending of workpieces made of strong metals.
Support rollers (3, 4) are installed in the required openings of the open frame (5, 9). They do not damage the pipe surface, but provide a secure fit.
This removable segment (6) is designed to be bent at 90 °. But with the appropriate configuration, it can be installed on a similar product of a different shape.
The robust body (10) is mounted on three supports (7). Rubber pads prevent the machine from shifting during work operations.
In addition to cleaning it from dirt, it is occasionally necessary to check the condition of the oil filter (11). No other routine procedures are needed.

For rolling, a mechanism with three rollers is used, which are fixed movably

Running in

In this technique, a workpiece of the desired shape is used. The pipe is pressed against it using a rotating roller and a lever.

At the right choice technology straight pipe can be bent as follows
With the help of the appropriate equipment, such decorative products are created

Important! Before bending the workpiece using a certain radius, you should study specialized reference books. They provide data on the permissible deformations of pipes made of different materials, with different wall thicknesses. If these instructions are violated, visible or hidden defects are formed in finished products.

Relatively small mechanical loads on working tools are created by levers and manual force. To work with durable metals, the equipment is equipped with hydraulics, electric drives.

A stationary machine is useful for quickly performing large-scale tasks
A manual device is mobility, the ability to perform work in a confined space

Creating a pipe bender with your own hands for a profile pipe: drawings and other preparatory operations

A simple bending device for aluminum and plastic workpieces is shown in this figure.

Such a device is not difficult to assemble quickly using available tools.

For the manufacture of such a structure, a solid board is needed. After marking, a round profile is cut out of it with an electric jigsaw. The rest is used to manufacture the support element. The created parts are rigidly attached to the reference surface. For the strength of the joints, in addition to screws, clamps are used. Next, the pipe is bent by hand until the desired shape is formed.

Before creating this simple pipe bender for a profile pipe with your own hands, it is recommended to make an elementary drawing with dimensions. A template made of thick paper, cardboard, on which the markings will be applied, will come in handy. It is clear that for the manufacture of more complex structures, it is necessary to prepare a full-fledged design documentation.

Such a simple device can be done quickly with your own hands.

It is not necessary to strictly adhere to engineering standards in order to make a pipe bender for a profile pipe with your own hands, a schematic image is quite enough. You just need to indicate all sizes, decide on materials, technological process and components. The project will help to solve several practical problems:

During the preparation process, it will become clear whether it is necessary to use welding and other special equipment.
A complete list of required components will be required for targeted visits to specific stores.
We must not forget that the machine must be protected from adverse external influences with the use of wood impregnation, metal painting.
Some parts will be too difficult to make yourself. The corresponding orders should be placed in the specialized workshops.

Important! When bending strong metal pipes it takes a lot of effort. In order not to risk unnecessarily, you can use drawings of a proven design, or copies of an industrial design.
