We bend the profile pipe with our own hands. How to properly bend a profile pipe with your own hands at home without a pipe bender: video

Profile pipes are indispensable in the process of assembling frames for building structures... Greenhouses, various greenhouses, gazebos and other objects are built with their help quickly and efficiently. However, things are not so simple.

To bend such a pipe, you have to use expensive special equipment, which is not always acceptable for home master... Let's talk about how to bend shaped tube at home.

A profile pipe is considered to have a cross-section other than a circular one. It can be rectangular, oval, hexagonal, or square. The pipe has increased strength, because its edges take on the role of stiffeners.

Profile products cope with significant bending loads, due to which they are good choice for the construction of a metal frame for buildings for different purposes.

The raw material for the production of shaped pipes most often becomes high or low alloy steel. Depending on the manufacturing method, electric-welded, cold-rolled and hot-rolled, seamless pipes are distinguished.

Products differ in wall thickness and profile height. These pipes can be used to make various parts in the form of frames, stairs and railings. Most often, a profile pipe is used in construction for construction arched structures and as a replacement for an iron bar in the construction of frames.

Skills in bending a profile pipe will come in handy for home craftsmen who want to independently equip a suburban area:

The simplest cold bending tools

Consider how to make two very simple fixtures, which will help to bend the profile pipe.

Profile holder

The workbench will become the basis for the device. It is important that not only work zone, but the space around her was free. To secure the mandrel, you will have to make several closely spaced holes in one edge of the workbench tabletop.

The actual mandrel or template is made of plywood. However, this option is only acceptable if several parts are expected to be completed.

The simplest pipe mandrel is made from thick plywood or plank. This template is enough for a few bends.

If it is necessary to bend a large number of pipes according to this pattern, the mandrel is best made from a steel angle. In some cases, the profile product must be bent at different angles.

For such work, you will need several templates at once, which should be prepared in advance. Before starting work, the mandrel is firmly attached to the base using clamps.

The pipe to be bent is securely fixed to its edge. Then bending is performed. The operation is performed smoothly, without sudden jerks. The force applied to the pipe should increase gradually. In the process of bending, the part takes the form of a mandrel. This will require significant effort.

Advanced bending plate

This is a convenient multifunctional device that allows you to carry out high-quality bending of a profile with your own hands. The device is a solid metal base plate mounted on a pedestal. The latter is fixed to the workshop floor using fixing bolts.

Plywood disposable blanks

Mandrel for narrow profile pipe

Alternatively, you can consider a similar device attached to a workbench. After work bending plate easy to dismantle and remove, or you can use it as a stand for other locksmith operations.

To make such a device, you need a thick metal plate. It is welded onto a telescopic support. For stops for bending, two holes are made on the base plate.

Bolts are placed in them. Nozzles of various radii are put on and fixed on them, which allows the pipes to be bent as needed. The pressure plate is cut from the thick sheet steel.

It is advisable to equip the bending plate with a pressure plate made of durable metal. It will allow you to maintain the alignment of the profile part during the bending process.

Its use is mandatory so that the coaxiality of the bent part is not disturbed, since bending a profile pipe without a pipe bender can accidentally deform it in two different directions. The plate is fixed over the attachments on the stop bolts.

The simplest way to bend a profile pipe:

There are quite a few ways to manually bend profiled pipes. And they all have a common drawback: it takes a lot of effort to bend them. A physically untrained master may not be able to cope with such a job. Bending of parts using specialized devices is much easier, more accurate and does not require much physical effort.

The problem is that the cost of such equipment is quite high. Therefore, buying a device just to perform a one-time job is certainly unprofitable. The best way- rental of specialized equipment, which will allow for a small fee to receive profile products bent exactly according to the template.

Almost all summer residents and owners of private houses have to deal with the question of how to bend a profile pipe at home. Arcs from a profile pipe are used in the construction of greenhouses, gazebos, awnings and arched canopies. Buying or making them with your own hands is economically unprofitable. They are needed for mass production, not for one-off production. Let us consider what methods exist for imparting bending to the profile pipes of the required radius.

The essence of this process is that one side of the pipe is stretched, and the inner part is compressed. Pressure is applied to the workpiece, which can be accompanied by heating to make the metal more malleable.

Bending a profile pipe along a radius with your own hands is associated with the following difficulties:

displacement of the longitudinal axes and planes of the part, which leads to misalignment;
rupture and the appearance of cracks on the outer part of the workpiece under the influence of the breaking force;
uneven compression of the inner part, leading to a corrugation effect;
changing the diameter or shape of the workpiece.

To know how to properly impart steel pipes the shape of the arch, a number of factors must be taken into account.

Influence of material on the choice of bending method

Profile pipes are made in accordance with the requirements of GOST 54157-2010 and have certain properties.

It is necessary to bend the profile pipes taking into account the following parameters:

Minimum bending radius facing material, which is planned to be laid on the arches. Have cellular polycarbonate these indicators depend on the thickness and structure.
Profile size and wall thickness. Products with a wall height of up to 10 mm are allowed to be bent using muscular strength. Profiles from 20 × 40 mm and more, you need to bend in a complex way, by pressure and heating or on a machine.
Elasticity (plastic moment of resistance). It must be invested in preliminary calculations, giving the workpiece a smaller bend radius.

Based on the analysis of this data, the choice of the method for performing the task is made.

Bending methods and bending devices

Using available tools and household tools, you can make a bending device at no additional cost.

As for professional devices, their cost can be several times higher than the price of material for making arches.

Consider the ways in which you can make bent rectangular arches perfect shape.

Cold

Cold rolling is bent without heating if the muscular strength of the master is sufficient for this procedure. As a rule, these are square pipes with a cross section of 10 × 10 mm and rectangular 10 × 20 mm.

If the walls of the blanks are thick, then the filling of the inner cavity with resistance is not carried out. Consider the main options for creating arches from metal blanks.

Lever with attachment

First, a piece is made with a certain semicircle length corresponding to given parameters... They make it from chipboard, plywood, drywall or boards.

After that it is necessary:

secure the vise firmly to a heavy and stable table. In a vice, a pipe section with a larger size than that of the workpiece is firmly fixed;
bend in several stages by inserting the profile into the hole of the segment clamped in the vice and applying force to it.

A lever of sufficient length is placed on the bendable fragment to create the necessary pressure to deform the metal. In the course of work, the curvature is controlled by a piece.

By mandrel

The mandrel is made on a solid base, which is a concrete or asphalt platform, a large workbench. In fact, this is a special template, along the contours of which the profile pipe will bend.

Taking into account the degree of elasticity of the metal, the master needs to give the mandrel a smaller radius.

The procedure is carried out in the following sequence:

the part is securely fixed to the base;
the end of the workpiece is screwed to one of its edges with wire or clamps;
the profile is bent until it is given the desired shape.

The template can be replaced with reinforcement driven into the ground. As the pipe deforms, it is sequentially welded to the pins. After the end of the work, the arch is cut off from the stoppers.

With the use of internal countermeasures (sand, water)

This method is used when the profile parameters are less than: height 10 mm, width 20 mm, wall thickness 1 mm. Pipes filled with a dense substance retain their shape better, even with strong pressure on a small area of the product.

The use of sand and water guarantees a quality result without scrap. And this factor is important, given the cost of rolled steel.

The filler must fill the cavity of the shaped pipe throughout the entire volume. It is much easier to achieve this with a liquid. The sand is rammed by vibration and spilled with water. Holes on both sides weld in or plug tightly wooden plugs... If heating is used, it is important to leave one of the sides uncorked for the gases to escape.

Grinder cutting and welding (sector welding)

Grinder cutting and welding does not require significant effort. The master needs to be prepared for the fact that this event will take a long time. The advantage of this technology is that there is no likelihood of damage to the profile, its shape can be corrected throughout the entire bending process.

The work is carried out in the following sequence:

A diagram is drawn up. It shows the distance between the cuts and their configuration.
Marking is applied to the profile. Triangular cuts are made along it with a grinder. The cut fragments are removed.
Bending of the workpiece is carried out. If the metal is elastic and unbends after compression, then the joints are immediately fixed by spot welding.
The gaps remaining after compression are welded or sealed. After the metal has cooled down, the seams are sanded and painted over.
The edges on the arch are almost invisible. When laying polycarbonate, small differences are compensated for by a thick seal.

Hot

Pre-heating is carried out in cases where the profile pipe has a large cross-section or thin walls. That is, it is either impossible to bend it manually, or it is fraught with damage or breakage of the workpiece. Let us dwell on the techniques that are used for thermal bending of rolled steel.

Using a spring and blowtorch

The spring is needed in order to prevent the profile walls from being pushed through during bending. In addition, the elastic insert will give finished product neat and even shape. It must be strong enough to absorb and withstand the pressure exerted on the profile.

The section is rigidly fixed at one end in the ground or in a vice. Before folding the piece, it heats up until the metal turns red.

It is possible to cool the bent place only with warm engine oil - the iron cracks and becomes brittle from water.

The use of a spring and blowtorch saves the worker from exerting unnecessary effort.

Hot forming

It is possible to give the desired shape to the profile without preliminary internal filling. When heated, the steel becomes so soft and ductile that it can be bent by hand, without the use of levers and complex devices.

For this, a convex semicircular stop is made. It must be made of material that is resistant to high temperature... Best for this is car drive or fireclay brick covered with clay. The part is applied to the template by the heated place. Then she flexes in one slow and precise movement. After a few minutes, you can continue the procedure.

Giving profile pipes the shape of an arch is a complex process that requires skills in handling household tools and metal.

When making arches, you should adhere to the following rules:

It is easier and more convenient to work with short workpieces. Before bending, it is advisable to cut the parts into lengths of 1.5-2 meters. Subsequent welding will not weaken the strength of the finished arch.
Heating the metal should be done slowly to prevent uneven heating and deformation. The resulting scale must be cleaned off immediately, as it is corrosive.
Steel rolled products must not be exposed to temperatures above + 800 ºС. Such an impact leads to destruction crystal lattice metal. The profile becomes soft or brittle.
All bending actions should be performed slowly, gradually increasing the load.

How much does it cost to bend a profile for a greenhouse

The cost of services is determined by the status of the workshop, its geographic location and the equipment used.

The average price for bending profiled steel is (in rubles per running meter):

10 × 10 - 80;
20 × 20 - 100;
25 × 25 - 110;
30 × 30 - 120;
20 × 40 - 125;
20 × 45 - 130;
40 × 40 - 140;
50 × 50 - 150;
60 × 40 - 160;
50 × 50 - 180;
80 × 40 - 240;
80 × 80 - 360;
100 × 100 - 480.

The cost may differ depending on the supply and demand market.

Special devices for bending

In order to achieve High Quality finished product, you can use.

Pipe bender

The tube benders consist of a bed, several rollers, stops and a drive. The device is controlled manually, by an electric motor and hydraulic cylinders. In private construction, profile pipes with a wall height of up to 20 mm are used. A manual pipe bender copes with their bending.

Conductor

This tool is designed for precise manufacturing and joining of profile joints when cutting with a grinder and joining arches with vertical, transverse and inclined posts.

Thanks to the use of a jig, the most accurate connection of parts at a right angle and a neat seam between them are achieved.

Bending plate

This fixture is a removable structure installed on a workbench or workshop floor.

For fastening, embedded parts are used or anchor bolts... The curvature of the base plate is adjustable with bolts.

After the end of bending, the equipment is removed, and the embedded parts are closed with plugs.

Making a bending machine with your own hands

About how to independently assemble a manual pipe bender, we already

When performing construction or renovation works around the house of various levels, the problem of bending shaped pipes regularly arises. This is usually necessary when building greenhouses on summer cottage, installing the gate, various designs for winter garden, at home, as well as in the arrangement of terraces. The profile pipes themselves have a high strength index, and in order to give them the necessary shape, you need to make some effort.

In this article, we will describe how it is faster and more convenient to bend a profile pipe on your own at home using special pipe bender equipment or using a conventional angle grinder (grinder) and welding machine... We will tell you all the secrets of correct pipe bending and describe a number of problems that can be encountered in this process. We will also tell you why you cannot bend square pipes with the help of special equipment.

Pipe bending technologies: how to bend a pipe correctly?

How to bend a steel or copper pipe correctly? Can this be done without losing the properties of the metal? There are several different technologies, one of the most convenient and fastest is the use of a special machine designed for bending shaped pipes. On the professional language it is called a profile bender, but the cost of such a device is quite high, so you need to have many good reasons to purchase it.

In the event that you plan to bend pipes a few times, then in specialized stores you can purchase special hand-operated pipe benders, with which you can bend pipes of various shapes, but this is most optimal for round pipes, because all elements have exactly a semicircular shape. The cost of such equipment is relatively low, usually it is about 3-3.5 thousand rubles.

For bending pipes at home, you can use more simple ways based on the use of a welding machine and an angle grinder. This technology will be described a little later.

Often copper, steel and polymer pipes with a small section width, it can be bent with the help of improvised means and physical efforts, but in this case it is difficult to control the bending radius. This method is best for copper pipes, since ordering its bending in a workshop is not cheap at all.

Features of bending using a pipe bender

The priority of using a special pipe bender in household it is worth considering even during the purchase of products, if you nevertheless decided to take a similar step. Most often, special equipment is purchased to work with large quantity shaped pipes, for example, in the construction of houses and the construction of fences. In this case, you need to immediately take into account what kind of pipes this device can bend, because often inexpensive models can only work with round shaped tubes.

Bend round or square tube with the help of a pipe bender, it is quite simple to do it yourself. In this process, only the wall thickness, the diameter of the pipe section, the radius of the future bend and the material of manufacture need to be taken into account. During operation, the bend is carried out in accordance with the technical tolerances of the pipe wall thickness and the size of the section, while during operation it is necessary to ensure that no kinks appear on the inside of the product, as well as flattening cross section profile.

When working with square pipes, when it is necessary to bend with a small radius, the force must be applied closer to the ends of the product, because in the central part the pipe will be very difficult to bend.

How to bend a profile pipe?

In order to bend the pipe not independently, but with the use of special equipment, it is necessary to use devices whose operation is based on cold stretching technology. In this case, stretching the profile leads to the fact that the neutral axis of the entire structure is displaced towards the required bend, therefore the probability of obtaining a corrugated part is practically zero. The pipe remains smooth throughout its entire length, fractures and other defects simply cannot appear on its surface, strength and other important characteristics remain the same.

The pipe bender wraps around the product very tightly, bends and stretches at the same time with absolutely verified movement of the bending template.

With the help of special equipment, the profile product can be bent in the right direction and at the required angle, preserving all the characteristics of the pipe and preventing the walls from losing stability. The secret of this technology is extremely simple, the bend is made in the presence of hydrostatic pressure inside. Special plugs are installed at the ends of the profile pipe, and liquid is fed into the system. Then the bending template is brought to the center of the product, and the required shape is achieved using the applied force.

How to bend a profile pipe without a pipe bender

You can bend the pipe at home quickly and easily enough, without resorting to using a pipe bender. This does not require the use of expensive and bulky tools and machines, but the bending quality is quite good, and the profile remains attractive. appearance without losing their properties. You can do this yourself using a welding machine and a grinder. Work is carried out according to the following instructions:

Initially, you need to correctly calculate the radius of curvature, optimally prepare a preliminary scheme, which will greatly simplify the process of work, make it high-quality and fast.
On the surface of the profile product along the length of the section that needs to be bent, it is necessary to make uniform cross-cuts on three sides. This is done independently using an angle grinder.
Next, you need to make some physical effort and bend the pipe in the required direction. Many professionals recommend that it be carefully fixed so that the bend is neat and the pipe is located in the same plane. This can be done, for example, in a vice.
Using the prepared welding equipment, all cuts are welded in accordance with safety regulations.
Now the welding spots need to be sanded and carefully processed.

This technology can achieve the most accurate results without the use of complex and specialized equipment, which is a pipe bender.

Pipe bending using internal means

Profile pipes of various cross-sections can be bent using means that have an internal effect on the structure. To do this, you first need to make a spring with a square section from steel wire, which has a thickness of one to four millimeters. The value must be selected in accordance with the profile thickness.

The prepared spring must be carefully wound, while the size of each section of the spring should be 1.5-2 millimeters less than the inner diameter of the section of the profile product, in this case the spring should be free inside the product that needs to be bent.

Now, with the help of a blowtorch, the section intended for bending is heated. This must be done very carefully, using pincers and protective gloves. After heating on a specially installed blank with a radius equal to the profile radius, the pipe is bent.

If the pipe needs to be bent in winter period or in a cold room, a slightly different technology is used. For this, the pipe is initially filled with water, and plugs are installed at its ends. After the profile is set in the cold, until the water inside the product completely turns into ice. Now the pipe can be bent independently on a blank without any serious physical effort.

Dural and brass pipes you can bend according to the same principle, if this is possible, then the shaped product will retain its properties and integrity.

How to bend a profile pipe at home

Any of the above methods can be used to create a pipe bend. All technologies are different necessary equipment, the time of the process and the necessary physical efforts. Of course, it is best to carry out this process using special equipment, but if this is not possible, you can use classical methods bending of profile pipes. A manual pipe bender can greatly simplify and speed up this process; you can find it in any hardware store at a fairly affordable price. However, if you already have a welder and an angle grinder, you can use them. The main thing - do not forget about safety measures, always wear a protective mask and special gloves, only then the process of bending the pipes will not be difficult and will not lead to possible problems.

Independent arrangement of a private plot may sometimes require bending a profile pipe for the construction of a greenhouse or gazebo. Some people think that this cannot be done without a special device, but there are several methods that may well cope with the task.

The nuances of pipe bending

The term "shaped tube" means square, oval and rectangular hollow products. Their round counterparts are also included in this definition, but they are used less often (more about the types of pipes -). Give the profile pipe a curved shape and at the same time keep it specifications difficult, but doable, if done on special device hot or cold method.

In this process, the profile is influenced by two efforts: with inside- stretching, and from the inner - compression. To counterbalance these efforts, several nuances are applied:

When bending the pipe, keep an eye on its outer wall. When heated, it expands very much and can not withstand the load, which leads to its crack.
It is necessary to carry out the bending slowly, then the risk of getting a bend will decrease.
After completing the process, you need to check the edges of the pipe, and if they lie in different planes, repeat the bending process to align them.
When choosing bending machine you need to focus on the thickness of the pipe walls and its cross section.
The inner wall of the pipe after the process may resemble an accordion, this is normal as contraction occurs.
It is necessary to start bending the pipe from the end, not from the middle, otherwise it will be more difficult to give in to the profile change.

Before doing bending, practice on unnecessary pipes to prevent marriage.

How to bend profile pipes by welding?

You can bend the profile pipe in a semicircle using a grinder. It is used to make several cuts along the entire pipe profile. This method is as follows:

Clamp the pipe in a clamping vise.
Make thin cuts in places of future pipe deflection.
Clean the cuts from dust chips, and carefully bend the profile along them.
Weld the holes formed by bending using a welding machine. With a small pipe diameter, a soldering iron can be used for these purposes.
Grind and grind the formed profile bends and process them protective compound, it will protect them from corrosion.

With it, you can get a pipe of the required radius. When choosing this method, you do not need to use a vice, the work progress is as follows:

Fix one end of the pipe in the ground and close it with any plug.
Fill the profile pipe with sand.
Preheat the blowtorch. Move it near the place of the intended fold.
Bend the pipe, but this must be done quickly so that the metal does not have time to cool, otherwise you will not bend it.

This "hot" method allows the use of water instead of sand.

Spring-loaded pipe bending method

This method preserves the integrity of the profile pipe walls. Before applying the method, preparatory work is carried out:

Spring preparation ... It is made of steel wire. The diameter of the latter depends on the thickness of the pipe walls. To wind the spring, a square section is used, a wire is laid around it. The outer diameter of the spring must be less than the inner dimension of the pipe.
Preparing the template ... Bending of the pipe will be carried out according to a previously made reference blank.

The deformation of the profile pipe is carried out by inserting a spring into it, which will protect the material from kinking. The part is warming up blowtorch, and in the hot state it is deformed to the required diameter.

Bending of profile pipes on a manual pipe bender (video)

The following video shows how to bend profile pipes with a cross section of 25 × 25 mm and 20 × 40 mm in order to make a frame for a greenhouse from them.

The pipes come with a wall thickness of 2 mm. Homemade pipe bender is a welded structure. It consists of a base of two small rollers sandwiched between posts. In the middle of the structure, there is a carriage made of corners. On their upper part, a square platform is welded into which a screw with a nut from a jack is inserted, and a removable handle is inserted onto it. A handle is also attached to the first roller, with the help of which the pipe is fed to the machine. A third roller is provided inside the carriage, the deflection arrow will pass along its center.

Pipe bending process:

Place the pipe on the two lower rollers and pull it to the required distance by scrolling the first roller.
Lower the middle roller by turning the handle.
Pass the entire pipe up to the marked mark in one direction. After rolling, it will become a little arched.
Perform the previous action only in the other direction, lowering the middle roller below. The pipe remains in the device and you need to return it to its original position by turning the handle on the lower roller in the opposite direction.
Run the pipe a third time through the pipe bender. The arc of its bend will increase sharply.
Repeat all steps for the 4th time.

As a result, you get a rather impressive radius of pipe deflection, so you can prepare required amount profiles.

In the next video, you can clearly see how you can make and use a pipe bender with your own hands:

The described methods using sand, welding and a spring are used for special cases in the household. If it is necessary to bend pipes often or it is planned to erect a large building with the help of them, then it is better to purchase a profile bender or make it yourself. When using a pipe bender, the process is faster, the profile is correct without unnecessary kinks.

Bending a profile pipe at home is usually required when a greenhouse is being performed arched type... The need for this work is created at the moment when the main frame is installed. There are many ways to bend structures with your own hands. Let's consider the main ones.

How to bend a square tube for polycarbonate structures

When installing polycarbonate greenhouses, a square-type design is usually used. In order to bend such a pipe at home, you will need the following tools:

Special machine for bending;
The structures themselves for performing arcs;
Ruler;
Bulgarian;
Welding unit.

To get started, you need to divide the structure into equal parts. Then filing is carried out by means of a grinder. The notch areas need to be processed with a spot welder. You can bend the profile pipe on a special machine. Is not simple job, because you need to scroll the unit manually.

If you do not have a machine, you can do the work yourself. For this, two structures are fastened parallel to each other. The drawing with the desired bend is performed on the ground. Then, in accordance with it, it is required to bend the first structure. According to it, a similar work is carried out with the second shaped pipe.

The profile structure can be bent by preheating the bending point gas burner or blowtorch. but this method has its disadvantages: laboriousness of work, poor appearance of the fold.

Much smarter to do the job with profile structure for the greenhouse by means of a pipe bender. Bending occurs due to the pressure of the roller. In this case, the bending angle can be controlled. The pipe bender can be done by hand. This will require:

Three rollers;
Metal table;
Bracket;
Concrete mortar;
Welding machine;
Steel structures with dimensions from 70 to 150 mm;
Lead screw;
Channel.

The structure is made of two steel pipes. They are fixed in the slab by means of mortar, and then attached, using a welding machine, to the channel. A distance of 600 mm must be maintained between structures.

The rollers are mounted on axles in one line. There must be at least 50 cm between them. The third roller is installed in the middle. It is mounted above two already installed rollers by 100 mm. Such a roller is lifted by a jack and is responsible for the angle of the bend performed.

When performing work, the roller is attached to a metal table. A bracket with a clamping axle is fixed to the axle. A roller is mounted on it, similar to the profile of the structure. The structure itself, during operation, passes through the rollers. At the same time, she sticks with her hands. At the end of the work, you need to check the angle of the profile pipe for the greenhouse by attaching it to the template.

How to bend a pipe using the hot method

You can give the design for the greenhouse the desired angle at home by paying attention to hot method fold. It has its advantages. In particular, the fold is smooth and smooth. To complete the work, it is necessary to place sand in the structure, then close its ends with wooden plugs. After that, it is required to drill holes in the plugs so that the resulting air escapes when heated. Then a mark is made on the structure for the greenhouse where it is optimal to bend. Then this place heats up. Following this, the heated structure is placed in a pipe bender and bent to the desired radius.

If you decide to bend a greenhouse structure at home, be sure to watch the video and photos that show correct execution such work. See all required material you can visit our website.
