Making a profile bender with your own hands - drawings of a homemade machine. How to make a profile bender with your own hands: views, drawings, manufacturing Device for profile bending drawing

The process of making curved parts is called flexible. Often, when carrying out such a process, pipes or profiles with a rectangular cross-section are used as blanks. This type of material processing gained great popularity long before the invention of the first metalworking machines: the metal was preheated at the bend point, which made it plastic, and then it was given the desired shape. However, preheating to a plastic state violated the crystal lattice and thereby changed the physical properties of the metal; the process was laborious and could not be used in large-scale production.

Features of profile pipe bending machines

Immediately after the emergence of profile tube bending machines, the cold bending process began to gain popularity in various industries, where large-scale production was established. Many began to make machines with their own hands. This growth in popularity can be attributed to the following features of bending machines:

You can get a part of almost any shape.
Depending on the thickness of the metal and its type, the shaping work can take from a few minutes to several hours. It is important to note that the requirements for increasing the time can be laid down in the drawings with the specification: obtaining a certain strength at the point of deformation, an indicator of the brittleness of the alloy, etc.
With the correct preparation of the technological process, the properties of the metal do not change.
It is possible to automate the work and use of such machines during conveyor processing.
The design of many bending machines is quite simple, which means it is reliable. It should also be noted the widespread use of home-made machines. With your own hands, you can create a structure that can be used in small-scale production when bending small-diameter pipes is carried out.

The processing itself is quite simple, but its application became possible only after obtaining alloys with a good ductility index. If the alloy is brittle, it cannot be used for cold bending.

Purpose and scope

There are a huge number of options for the execution of bending machines, especially for homemade options. Despite this, the following similarities can be noted:

They can be used to obtain blanks of only a certain shape. For example, some are used to obtain a right angle, others are bent in a circle, others are designed for spiral winding, etc. However, there are also complex installations with the possibility of changing the machine. Thus, the installation of rollers of a different diameter and profile in a bending machine allows you to change the bending angle.
A very important indicator can be called the features of the pipe profile, cross-sectional diameter, wall thickness, type of alloy. These indicators have an impact on the possibility of using a particular bending method.
Alloys that can undergo cold bending: aluminum, alloy and copper alloys, steel. The power of the machine determines the ability to process pipes with a certain cross-sectional diameter and wall thickness, in some cases, the processing speed.

Application area:

Petrochemical industry.
Mechanical engineering.
Construction.
Energy and electrical industry.
Shipbuilding.
Light industry.

When cold bending is performed, the metal is subjected to strong loads, and the increase in ductility is caused by partial heating in the area of occurrence of these loads (only during fast bending). That is why, both when using professional and home-made machines, it leads to the following changes in metal:

Thinning of the walls at the bend site.
Flattening the pipe at the bend. At the same time, it is rather difficult to give the original shape.
Formation of kinks and corrugations.
With significant indicators of the elasticity of the material, it is possible to change the resulting shape after bending.

Making a homemade bending machine with your own hands

The structure with which the bending is carried out can be created by hand. To work you will need the following:

Three shafts, which can have a flat or recessed profile of the end surface. It should be noted that the presence of a recess with a profile for the workpiece will make the structure more efficient. You can make a profile with your own hands. These shafts will bend.
The metal profile that will be used to create the frame.
Chain-type drive mechanism.
Chain.

The whole process of creating a pipe bending structure can be divided into the following stages:

Create a frame that looks like a longitudinal table. The elements can be connected by welding, but taking into account the possible stress during operation, bolts and nuts should also be used. When creating a frame with your own hands, it is worth remembering that it must have good stability. Therefore, it should be possible to attach it to the floor.
Two shafts, which have an axis of rotation, are attached just above the table at a certain distance, the third is slightly higher in the middle. Mounting method - bolt and nut.
The distance between two shafts located in the same horizontal plane determines the bending radius. Therefore, several options for their location should be envisaged (but they should always be equidistant from the central shaft). Thus, you can make a machine with your own hands that can be used to produce parts with different bending angles.
We carry out the fastening of the chain drive.

In a similar way, you can make a simple and reliable structure for bending pipes with your own hands.

The profile pipe bending machine is a very popular type of metalworking equipment. This is explained by the fact that pipe products of this type are actively used today in many areas, including for solving household needs. If cutting a profile pipe is easy even with a hand tool, then a special pipe bending machine must be used to bend such a product.

There can be only two options for obtaining such a machine at your disposal: the purchase of serial equipment, for which it will be necessary to allocate significant financial resources, or the manufacture of a device for bending shaped pipes with your own hands. Today there are many design schemes, according to which homemade machines for bending shaped pipes can be manufactured. It is worth dwelling on the simplest of them and, accordingly, the most popular among home craftsmen.

Pipe bending machine device and instructions for its assembly

Regardless of what consumables and mechanisms are in your home workshop or garage, a do-it-yourself profile pipe bending machine can be made according to various design schemes. Having made even the simplest home-made pipe bender, in the future, if the need arises, you can improve its design by endowing such equipment with a number of additional functions.

The main structural elements of any machine on which it is performed are:

supporting frame, which is made of a powerful metal profile;
three shafts rotating on separate axes (precisely by means of such elements, which should be of high strength, bending machines act on the profile pipe, deforming it to the required bending angle);
a mechanism by which the working shafts are rotated;
chain connecting the elements of the drive mechanism.

Before making homemade bending equipment, it is advisable to prepare its drawing or find a ready-made one on the Internet. Moreover, there you can find a video with detailed instructions explaining the process of manufacturing a device for bending shaped pipes.

If the equipment for bending, equipped with working shafts, is used for rolling a profile pipe, during which it is bent, then the profile bending devices of the simplest design in question work according to a different principle. On devices of this type, it is carried out, which must first be formed from rigidly fixed elements. Strong metal pins fixed in a concrete base are most often used as such elements. An arc is formed from such pins, along which the bend of the professional pipe is performed.

To make a device on which it will be possible to effectively bend the pipe along the radius, it is best to pour the concrete platform on your own and fix the metal pins on it as securely as possible.

The bending of steel pipes, for which such a simple device is used, is carried out in the following sequence.

One end of the pipe is securely fixed.
Physically acting on the second, unsecured end of the pipe, the product begins to bend smoothly and accurately, bending around the surface of the pins located in an arc.
After the pipe has acquired the required configuration, its second end is also fixed and the product is left in this position for a while so that the metal gets used to the new state.

Since work on such a device requires the application of significant physical efforts, to facilitate the task (especially when bending large diameter pipes), the place of the future bend is preheated with a gas burner or over a fire. You can learn more about the rules for working on such a device in the corresponding video.

Of course, such a device that can be built in the yard of your home has minimal efficiency and functionality. For example, with its help it is rather difficult to perform bending of stainless pipes or to carry out complex bending. Nevertheless, it is quite possible to use it for the simplest bending work. Such work, for example, can be associated with laying a pipeline or making a frame for a home greenhouse.

This lever tube bender is not too difficult to manufacture and allows you to work with fairly thick pipes

A video from the author will allow you to understand the key points and small nuances of the manufacture of this pipe bender.

Serial equipment

If working with metal pipes of various profiles is related to your professional activity, then the best choice for you will be serial machines for bending profile pipes, which are distinguished not only by high efficiency, but also by extended functionality. Today there are many different models of profile bending machines, which differ from each other both in their performance and in the set of functionality. Such a variety allows you to choose a machine for performing bending of a shaped metal pipe, focusing on your needs and financial capabilities.

Let's consider the most important advantages that a serial machine for bending shaped pipes has over manual devices.

Some models can be equipped with an electronic control system, which allows automating the bending process.
The use of replaceable working attachments significantly expands the functionality of the profile bending machine.
In addition to the electronic control system, some models of such machines can be equipped with a remote control.
Serial profile benders are characterized by compact dimensions, which makes them very mobile.
Such equipment can be installed on any level and solid surface.
The technical capabilities of such machines allow you to perform even very complex bends on pipes (U-shaped, N-shaped, etc.).

When choosing a serial machine for bending shaped pipes, it should be borne in mind that the cost of such equipment, depending on its technical characteristics and functionality, starts from several hundred US dollars and can reach several thousand.

To carry out bending operations on serial equipment, you must have a certain training. If it is not there, then you can study the features of this process from the video, which is easy to find on the Internet.

The need for a device that is capable of bending shaped pipes arises in many cases. A similar tool is necessary when arranging a gazebo, shed, creating greenhouses. Curved pipes are sold on the market today, but the high cost makes their purchase unprofitable. It is much cheaper to build and create bent shaped pipes yourself.

Types and design features of profile benders

Machines capable of bending shaped pipes differ in design from conventional tools. Profile materials have increased strength. Accordingly, in order to bend them, more effort is needed.

In addition, usually the bend of a shaped pipe has a large radius. In this regard, the profile bending structure includes three rollers. Of these, depending on the preferences of the master, mobile can be:

left roller;
middle roller;
right roller.

Pipe bender roller

If the middle roller is movable, the end elements are fixed to the body. They rise slightly above the base plane. If one of the extreme rollers is movable, then it moves together with the base. Others remain immovable during this time.

The principle of operation of such a tool is quite simple and is based on cold rolling. The shaped tube is placed between three shafts. The pressure that bends the metal is created by the center, middle roller. If the pipe needs to be bent only in one specific area, a special spotting machine must be used. The rolling machine allows you to obtain an arched profile.

Depending on the application of what force the machine works, the following types of profile bending are distinguished:

mechanical. The bend is created by manual pressure;
hydraulic. Additionally, a hydraulic jack is used, with the help of which pressure is created;
electric. The machine is equipped with an electric motor that creates a bending force;
electrohydraulic. The electric motor drives the hydraulic cylinder.

If the machine is designed for small pipes, a hand-broached tool will do. Otherwise, it will be impossible to stretch the profile without special devices (for example, an electric motor).

What materials and tools are needed to make a pipe bender

On the modern market there is a wide variety of tools designed for profile bending. They differ both in capabilities and functionality, and in price. However, any master can independently make such a machine, paying only for individual component parts. Some of them may already be in stock, others will have to be purchased.

So, to create a machine, you need to acquire:

corners;
chain;
chain tensioner;
blanks for the manufacture of rollers and shafts;
channels;
bearings;
bearing housings;
drive sprockets;
hydraulic jack;
drive shaft handle;
springs (if a jack will be used);
bolts and nuts.

There are many options for the manufacture of machines for bending shaped pipes. Some of the details in the list above may not be needed. It all depends on the chosen method of creating the instrument. In addition to materials, you will also need tools. In order to create a machine, the master will need:

drill (electric);
welding machine;
hammer;
grinder (angle);
drills (for metal);
open-end and socket wrenches.

The most difficult task is to manufacture the pressure roller and drive shafts. To create them you will need. Not every master has such equipment. However, you can find a turner who will do all the necessary work for a reasonable fee.

Build process

Before starting the assembly, it is strongly recommended to create a drawing of the future device. This will make the task much easier. Although today there are a large number of ready-made drawings, it would be better if the master creates it himself, taking into account his own needs.

The whole process of creating a pipe bender for a profile pipe with your own hands consists of the following steps:

Creation of a roller and shafts (in the absence of proper qualifications, it is better to entrust this matter to a professional turner).
Installation of bearings in races.
Determination of the location of the keyways on the shafts.
Drilling holes in restraining nozzles, tapping threads for clamping bolts.
Creates the site on which the pinch roller will be installed. In (if there is none, a thick metal plate will do) four holes (paired) are drilled, for which the cages with bearings will be attached.
Screwing on the pressure shaft.
Welding lugs to the pad (M8 nuts are used).
Manufacturing of the bed and supporting legs using a welding machine.
Suspension of the platform on which the roller is installed to the bed using springs (use the top cross member of the bed).
Drilling holes in the base frame. With their help, a variable distance between different shafts will be provided. In this case, it is necessary to carefully monitor the distance between the holes, since in the event of an error, the pipe will not only bend, but also compress.
Installation of support shafts. Installation of driven and driving sprockets, drive chain.
Tensioner installation, chain slack elimination.
Creation of the drive handle. As a starting material, you can use a steel bar with a diameter of twenty millimeters.
Installation and fixing of the jack on the upper platform. Nuts and bolts can be used for fixing.

After assembly, it is recommended to conduct a test during which assembly errors (if any) will be found. To do this, you need to put a piece of the profile pipe on the lower shafts, and press it against them with a jack. Next, you need to activate the device by turning the handle.

Another device option

You can create a machine for bending a profile pipe with your own hands in another way. This will require fewer materials. It will be possible to do without an expensive jack. The process of creating a simpler machine consists of the following steps:

Create a frame that looks like a longitudinal table. Welding can be used to connect the elements. In this case, it is necessary to take into account the voltage that will be exerted on individual elements of the device. It is important that the frame is stable. This can be achieved by fixing to the floor.
Fastening two rotating shafts just above the table. The third shaft is placed even higher, between the first two. The distance between the outer shafts and the central element can be changed. This will affect the bend radius. However, it is important that both end elements are at the same distance from the center shaft. In the future, this parameter can be changed depending on the bending radius, which must be obtained in a particular case.
Chain drive attachment.

This machine has a simpler design. However, working with it is somewhat more difficult than with the previous device. In any case, after making the tool, it is recommended to clean it from rust and paint it. This will protect the pipe bending machine from damage.

The first machine is more detailed. Pipes bent on such a unit will have a more neat appearance. In addition, less force is required to machine the profile. The second machine is cheaper and easier to manufacture. However, the bending quality may be inferior. What tool to make should be decided by the master himself, focusing on his needs.

Thus, the profile tube bending machines can be manufactured independently. The final cost of such tools will be lower than industrial products on the market. To create a machine, you will need certain materials and tools.

There are a large number of drawings of such devices, but it will be better if the wizard creates the drawing himself, taking into account all the features. You can make the tool, focusing on the instructions above.

Humanity has begun to adapt to iron since the discovery of iron ore. After all, after the metal has been melted, when pure iron is obtained, it must be processed with something. That is why people, over the years, have been creating make-ups in order to more conveniently process any metal. Such devices began to be called machines. There are a myriad of these easel assemblies, mechanical or electrical.

At the present time, such equipment costs a lot of money and not everyone can afford to purchase it. However, thanks to world progress, the skillful hands of our society have learned to do something similar from improvised means.

Typically, these analogs are mechanical. Since electrical equipment, even in a used state, is now not cheap. Prototypes of qualified modules are reproduced according to a more simplified scheme. Due to the fact that all parts of mechanical devices are created from used parts of aggregate units.

The article will focus on how to make a profile bending, its modified models, assembly features, and drawings of this machine building will also be presented.

Tip: Before you break down and start looking for parts for a mechanical unit, decide which type of installation is right for you. Well, after the choice, you can understand how to make homemade assembly and start assembling the future iron brainchild.

These mechanical devices differ in several ways:

By the variety of installation, that is, by the way the bed is used (in production, in a certain place, etc.).
By variation of driving use (using electricity or manual power, etc.).

Consider the first criterion for distinguishing between bending machines that are found in everyday life. According to the methods of installing the machine, there are three types:

The first type refers to a stationary location

Such units are very heavy.

Without special equipment and technology, such devices cannot be moved on their own. They are used in large factories for serial production. The machine shown in the photo has a factory name UGS-6 / 1A... However, such a large unit would be out of place in your garage or workshop.

Second view

Portable homemade unit. It can be a little small.

The weight of such a device is not large, sufficient for transferring from one place to another.

Such a machine is used in small industries or has a private application. It can be used directly in the place where you are going to work.

Third kind

It is a compact, small-sized machine tool related to the type of wearable tools.

Such a tool can be easily carried with you, for example, if you are asked by a neighbor or friend.

Or you need to take him to the dacha, so you can safely put it in the trunk and not know the problems. Very few details are required to create this piece of iron tools.

According to the second category, the device for bending pipes can be divided into three types, differing in the drive

Hydraulic action

The mentioned type of drive has a pneumohydraulic car jack. It is due to him that the main influence on the workpiece is supplied.

Exposure to manual force

In this case, the drive means the human hands, and the force is transmitted due to the contraction of the muscular system. It is such a drive that is very popular among hand-held machine tools.

Electric drive

This drive uses an electric motor, due to which all the effort is distributed to all the necessary parts of the mechanism. As a rule, such drives are used in production.

The difference between machines in the method of bending pipes and profiles

Due to the fact that finished metal products have different radii, diameters, and so on, there are also different types of bending. In modern society, there are only four types of bending of products:

Bending metal according to a prepared template

In this case, wooden parts are used. Such a mini-machine is usually called "bow" or "bending". They are used for bending soft metal tubes. The impact on the fold is performed strictly by manual force. The exact diameter, in this case, is practically impossible to achieve. It is easier to assemble the device according to the factory dimensions.

By extrusion

It is a press without a matrix by means of one punch. A punch is a part of the mechanism that directly acts on the part to be pressed.

By pressing

This process should be done smoothly and carefully. Overfeeding can ruin your workpiece.

Consequence of rolling

The metal is rolled by pulling the part through two parallel rows of rollers.

Tip: If you are going to bend the pipe at home, then fill it with plain, river sand and be sure to besiege it with a hammer. This will give the pipe safety and improve the distribution of forces on the round pipe.

Assembling the machine with your own hands

Before you are going to make such an installation with your own hands, please read the necessary literature, which will contain everything related to rolled metal. There are various assemblies of such machines. As the saying goes: "Who, in what way!" The construction details of the mechanism can be varied, the essence does not change from this.

Tip: If you do not know where to start designing a tool, make a preliminary drawing with actual dimensions. This will allow you to fully present the whole picture and correct the shortcomings!

example assembly

The result is a wonderful homemade machine that you can use. The resulting machine is shown in the photo.

During construction work, metal products are often used. Most often they are mounted on straight sections, so there are no problems. However, there are cases when the structure has a curved shape, then it becomes necessary to bend the pipe (for example, a profile for a greenhouse device) at a certain angle. In production, this process takes place with the help of professional pipe benders. However, in private construction, when you need to carry out a small amount of work, there is no need to buy an expensive device. In this case, you can make a simple do-it-yourself profile bender or purchase a manual pipe bender with a minimum number of functions. More on all this later.

Read in the article:

What is a pipe bender for?

Due to the improvement of production, modern devices can bend pipes of any size and from any material (for example, steel, PVC, aluminum) up to 180 °. This equipment is indispensable when carrying out complex construction work and, especially, when laying utility networks (heating, water supply, gas supply, and so on). In addition, they are often used for the improvement of personal plots.

The following elements can be folded with the help of the profile bender:

Beams.
Solid workpieces of rectangular or square shape.
Channel bars.
I-beams.
Pipes.

Design and drawing of a pipe bender for a profile pipe

Profile pipe bending device - manual, electrical or mechanical equipment with relatively small dimensions and weight. The work uses cold rolling technology. And for the curvature of the optimal parameters and the processing of parts of different sizes and types, special nozzles are used.

Roll forming machines are roller mechanisms and come in four types:

With top movable roller.

The most common and simplest form. At the same time, if the profile bending is manual, the roller moves under the control of the gearbox, if it is hydraulic, it moves under the control of the hydraulic system. The error of this type of device is minimal.

With left movable roller.

In addition to the usual bending of the part, this device is capable of curling spirals. To control bending, such machines are equipped with a CNC with the ability to preset the process parameters. Therefore, the bending parameters of the finished product correspond to the initial parameters as much as possible.

Machines with movable lower colic.

They are used for bending large workpieces. Such pipe benders are only hydraulic and are fully automated.

Pipe benders, all rollers of which move during operation.

The most technologically sophisticated device that contains the advantages of all of the above types. He is able to carry out a full cycle of bending work on a part.

Drawings of both a purchased and a homemade pipe bender for a profile pipe depend on the type of device. But there are elements that are present in every device: frame, tube stops (two or more), shafts.

The frame (or bed) is designed to secure the rest of the parts to it. It can be of one of two types:

Closed(it has a complex design, therefore it is manufactured in factories; it requires certain skills during operation, but it is safer than open).
Open(typical for a pipe bender made by hand according to drawings; the dimensions of such a frame are relatively small, so it is not difficult to use it).

How does a profile pipe bender work?

Pipe bending machines bend parts, and profile bending rolls (or rolls for a profile pipe) deform the workpieces by rolling them. For all devices of this type (both professional and self-designed), the principle of operation is almost the same.

Before starting work with the part, you need to remove the grease from the device with a dry cloth and run it idle for about half an hour. This is necessary to detect errors and breakdowns before starting work. If faults are found with a part in the device, it will be much more difficult to eliminate them.

Important! Remember to ground and check all connections (electrical and mechanical) before starting work.

Now let's set up the shafts for the pipe bender of the profile pipe (buy or order in the workshop which will not be difficult and will not take a lot of money when making the device yourself):

The nuts of the rollers (support and pressure) are unscrewed.
The rollers for the profile bender are installed and fixed (the purchase of which, when making the device yourself, can be carried out in any profile store).
The pressure roller rises.
The workpiece is cleaned and fixed (with the help of special bolts).

Further, the part is deformed by rolling it between the shafts, therefore, to adjust it, it is enough to move the upper shaft up or down. Moreover, in a hand-held device, this happens by raising the lever, in an electric device - using an electric drive.

Profile pipe bender: types

There are several classifications of profile benders: by mobility (stationary, portable, portable), type of transmission mechanism and type of drive. The last division is the most important in order to understand the structure of the profile pipe bending machine and do it yourself.

The profile tube bending machine can be executed with one of three types of drive: manual, hydraulic or electric.

Hydraulic pipe bender for profile pipe

This type of roll is widely used in the industry due to its ability to process parts of any size quickly and efficiently. In addition, such a device is often used when working with water supply and sewerage pipelines.

Despite the complexity of the hydraulic pipe bender device, it is quite possible to make it with your own hands. You only need a little experience with industrial equipment.

Electrically driven profile tube bender

This equipment is very large and heavy, but requires a permanent installation. The electrically driven roll forming machine is capable of performing precise work without loss of quality. They can be completely electrical or electromechanical. The second type is cheaper, but requires partial manual control. Electrical devices can be equipped with automation for long-term autonomous operation (however, the cost of such pipe benders is quite high).

Devices of this type are used mainly in enterprises and in private workshops. For bending profile pipes at home, a manual pipe bender is better suited.

Manual profile bending machine

The most popular option among small workshop owners and people dealing with flexible pipes at home.

The advantages of this device:

Low cost. Manual roll benders can be purchased at a very attractive price due to the simplicity of the device and low production costs.
Light weight and mobility. It is easy to carry from place to place, as the design does not provide for a base.
Rare breakdowns. Due to the lack of electronics, the manual profile bender rarely fails. And if this happens, the repair will not take much time and money.
The ability to assemble a homemade pipe bender. A machine for bending a profile pipe can be made at home (for example, a pipe bender from a house).

Disadvantages:

Relatively low accuracy of work. There is no hardware control in hand tools, so the bending accuracy depends only on your skills.
The need for physical effort.
Impossibility to work with large sizes. With the help of a hand device, you can bend parts with a maximum size of 4x4 cm.
Spending a lot of time for the most accurate execution.

Thus, for work at home, a hand-held device is sufficient. If you are going to carry out a large amount of work, and at the same time use large workpieces, you should take a closer look at electronic or hydraulic pipe benders.

How to make a pipe bender: step by step instructions

For rare use or a small workshop, a self-made pipe bender for a profile pipe will be quite enough. How to make such a device yourself? First you need to decide what task the manual pipe bender should perform.

For home use, a device capable of deforming pipes of a small section is sufficient. The above video answers the question: how to bend a profile pipe with your own hands at home without assembling a complex device?

The second method consists in assembling a pipe bender for round pipes of a small cross-section, consisting of several parts: a slab of concrete as a base, metal pins and a drill.

Procedure:

Applying a dimensional grid to a slab, the cells of which are 4 × 4 or 5 × 5.
The deepest holes are drilled at the intersections of the lines.
Pins are inserted into the holes.
A pipe is inserted between the pins and bent in the required direction.

Bending profile pipes with your own hands using this device is physically difficult, therefore this method is only suitable for products of small diameter.

How do you make a manual device for larger parts yourself? The profile bend from the jack is perfect for pipes of large cross-section. In this case, the jack is securely attached to the bed (it is advisable not to use it for any other purpose in order to prevent loosening of the structure).

Note! When the pipe is deformed, it is supported on rollers, and the jack slowly presses on it with the help of a "shoe". In this case, a smooth bend is formed, which does not affect the strength of the workpiece.

Conclusion

A homemade profile bender is an excellent solution for rare use in a small workshop. However, if you approach its assembly responsibly, you can design a device that can bend not only small-diameter products (for example, a pipe bender from a jack). A correctly drawn up drawing is important, the dimensions on which are indicated for each element. The main thing is to follow the instructions exactly, then you can make a reliable and durable device.
