With a question how to bend profile pipe At home, you have to deal with almost all dacms and owners of private houses. Arcs from the profile tube are used in the construction of greenhouses, arbors, canopies and visors of arched shape. Acquisition or making them with your own hands is economically unprofitable. They are needed for mass, and not for single production. Consider which methods of imparting to the profile bending pipes of the desired radius.
The essence of this process is that one side of the pipe is stretched, and the inner part is compressed. The preparation is pressure that can be accompanied by heating to make metal more supplied.
Bending the profile pipe along the radius with their own hands is associated with such difficulties:
To know how to properly give steel pipes the form of the arch, it is necessary to take into account a number of factors.
Profile pipes are made in accordance with the requirements of GOST 54157-2010 and have certain properties.
Flexing profile pipes must be tailored to such parameters:
Based on the analysis of this data, the choice of a method for performing the task is made.
Using breeds and household tools, you can make a bending device without additional costs.
As for professional devices, their cost can several times higher than the price of the material for the manufacture of the arches.
Consider ways with which you can make curved rectangular arches of the perfect form.
Without heating, cold robes are bent if there is a sufficient muscular power of the wizard for this procedure. As a rule, this is a square pipe with a cross section of 10 × 10 mm and a rectangular 10 × 20 mm.
If the walls of the billets are thick, then the filling of the inner cavity resistance is not carried out. Consider the main options for creating an archer from metal blanks.
First, melo is made with a certain semicircle long, corresponding to the specified parameters. Make it from chipboard, plywood, drywall or boards.
After that you need:
The lever of sufficient length is attached to the bend fragment to create the desired pressure for the deformation of the metal. In the course of work, curvature is controlled by lecture.
The mandrel is made on a solid foundation, which is a concrete or asphalt platform, a large workbench. In fact, this is a special pattern, the profile pipe will be bent along the contours.
Given the degree of elasticity of metal, the master must be given a smaller radius.
The procedure is carried out in such a sequence:
The pattern can be replaced by reinforcement, driven into the ground. As the pipe deformation, it is successively welded to pins. After the end of the work, the arch is cut from the stoppers.
This method is used when the profile parameters are less than: height 10 mm, width 20 mm wall thickness 1 mm. The pipes filled with a dense substance are better preserved form, even with a strong pressure on the small area of \u200b\u200bthe product.
The use of sand and water guarantees a qualitative result without marriage. And this factor matters, given the cost of steel rolled steel.
The filler should fill the cavity of the profile pipe throughout the volume. It is much easier to achieve this with a liquid. Sand tram vibration and spill water. Holes on both sides are brewed or tightly clogged with wooden corks. If you use heating, then it is important to leave one of the parties not clogged to exit gases.
Cutting with a grinder and welding does not require a significant effort. The master must be prepared for the fact that this event will take a lot of time. Plus, this technology is that there is no probability of damage to the profile, its shape can be adjusted throughout the entire bending process.
Work is carried out in such a sequence:
Preheating is carried out in cases where the profile pipe has a large cross-section or thin walls. That is, it is manually to bend it or impossible, or it is fraught with damage or breakdown of the workpiece. Let us dwell on the receptions that are used for the thermal bending of steel rolled steel.
Spring is needed in order to prevent the profile walls during their bending. In addition, the elastic insert will give the finished product a neat and even shape. It should be strong enough to take over and withstand pressure rendered on profile.
The section is strictly fixed in one end in the ground or in vice. Before you get a fragment, it warms up until the metal becomes red.
It is possible to cool the bent place only with warm engine oil - iron from the water is cracking and becomes fragile.
Using the spring and soldering lamp eliminates the employee from the applied of excessive effort.
It is possible to give the desired form a profile without prior internal filling. When heated, the steel becomes so soft and plastic that it can be bending with hands, without the use of levers and complex devices.
For this, a convex addition of a semicircular form is made. It must be made from a material resistant to high temperature. It is best for this car disk or chamotte brick, an incelaved clay. Heated place the detail is applied to the template. After that, it bends one slow and accurate movement. After a few minutes you can continue the procedure.
Giving the shape of the form of the arc is a complex process requiring the existence of access skills with household instruments and metal.
In the manufacture of the arches, such rules should be followed:
The cost of services is determined by the status of the workshop, its geographical position and applied equipment.
The average price for flexing profile rental is (in rubles for the temporon meter):
The cost may differ depending on the market of demand and suggestions.
In order to achieve the high quality of the finished product, you can use.
Pipe benders consist of beds, several rollers, limiters and drives. The instrument management is carried out manually, electromotor and hydraulic cylinders. Private construction uses profile pipes with a height of the wall to 20 mm. With their flexion coping with manual pipe bender.
This tool is designed for accurate manufacture and connection joints of the profile when cutting the grinder and the arches with vertical, transverse and inclined racks.
Thanks to the use of the conductor, the most accurate connection of parts at a right angle and neat seam between them are achieved.
This device is a removable design installed on the workbench or on the floor of the workshop.
For fasteners, mortgage parts or anchor bolts are used. The curvature of the support plate is regulated by bolts.
After completing the flexible, the equipment is removed, and the mortgages are closed with plugs.
About how to assemble the hand-made pipe bending
The task, how to bend profile pipe, very often gets up in front of domestic masters. Facilities from profile pipes are multifunctional and comfortable. They are used when creating greenhouses and canopies, fences and supports under plants, racks and other things. As a result, it turns out a very durable, stable and relatively inexpensive design. At first glance, the task bend the profile tube without a pipe-bender seems not solved. However, if you know some subtleties of the upcoming case, it is not so difficult at home with an arched pipe.
Task: Bend profile pipe without pipe bender - solved!
Before you bend the profile pipe at home, you need to clearly imagine that it is based on flexible. Regardless of the form of the profile pipe, we have to give it the bending of the specified radius. The result is achieved or a purely mechanical impact, or using additional heating profile. At the same time, two different forces act at one moment:
It is because of the multidirectionality of the affecting forces to bend a profile pipe at home is not so simple. The fragment of the workpiece can linger the alignment, the result of which will be the multi-level location of the pipe segments. The outer surface on bending can burst from loads. From the inside, the profile pipe with compression can collect the folds, making the surface similar to the corrugation. In addition to not aesthetic external view, such an outcome makes the profile fragile.
Possible deformation of the pipe
If not observance technological nuances, to give a profile pipe curved form at home without marriage will not work. You can reserve a bunch of blanks and without reaching the desired result. So it is necessary to take into account the physico-chemical parameters of the material from which the pipe is made, the size of the cross section of the workpiece and the thickness of its walls, the radius of the expected bending, ideally need to be carried out. Knowing all these parameters makes it possible to bend profile pipe without damage to blanks.
Profile pipes are available with a variety of sections: in the form of a circle, square, rectangle, oval. At home, the master prefers to apply square and rectangular metal rolling. This choice is explained simply: an outdoor coating is easier and more reliable on the pipes of this type.
At home, the master prefers square and rectangular metal
To determine the allowable bend radius of a square or rectangular profile, you need to know its height and stick to such rules.
Before you bend a profile tube at home, also pay attention to the thickness of its walls. If they are thinner than 2 mm, it is better to refuse the flexion: the quality bend will not work. When using such a metal rolling to create pipe structures, it is better to connect welding.
It has its own features of the flexible tube from low-alloyed or carbon steel. Such blanks after flexion are played, returning to the original form. So the master will need to repeat the template. In some cases, secondary flexion can be avoided if initially set the bending radius greater than is required. Then the sake will lead the pipe at the end of the process to the planned result.
The sink degree is characterized by a plastic resistance torque denoted by WP. Its parameters are necessarily available in the documentation for metal rolling. The lower WP, the less the workpiece will spring when flexible.
Bend the profile pipe is possible both in a cold way and with heating. Heating is carried out by gas burner; At the same time, the plasticity of the material increases significantly, and the achievement of bending takes less effort. However, the blanks of a small section have and without heating sufficient plasticity, so you can do without a burner.
Clear rules for the use of heating are designed exclusively for pipes with a cross section in the form of a circle. It is considered mandatory when flexing the blanks, whose diameter is more than 10 cm. When operating with square or rectangular profile pipes, it is necessary to rely on or on your experience, or on the recommendations of other masters. In the first approximation, you can focus on the following tips:
At intermediate values \u200b\u200bof this indicator, the flexion method is left at the discretion of the wizard. To make a decision on the method of flexible profile without pipe bender, it is possible to carry out an easy check. One end of the workpiece is clamped by visits. On a free end, a tube cut, having a larger diameter of the inner section. It turns out pressure on the resulting lever. If the metal turns out to be bend, it means that further bending along the desired template can be conducted in a cold way.
Flexing with a cold way
Profile pipe little size Without a pipe bender bent in fact with hands, with the help of simple fixtures.
To obtain a smooth bending of pipes, having a profile height of more than 10 mm, it is recommended to fill the filler. As it is usually used mediterranean sand or rosin. An alternative method bend the workpiece without heating and pipe bending - instead of filler, apply a spring having a dense pump. This method is especially good in cases where the walls of the metal is too thin. The spring is selected in such a way that it is freely entered into the profile pipe, but at the same time it filled it enough tightly. To facilitate the extraction of "filler" after the end of bending to the end of the spring, the wire is securely mounted.
Bending process
In the presence of some plumbing skills, the spring of the specified size can be made independently, from steel wire with a thickness of 2 mm.
If you decide to bend the pipe by heating, it must be filled with filler. Because to deal with high temperaturesThe mandatory set of "equipment" includes protective mittens from tarpaulin.
Hot method bending
The procedure for performing work is followed by the following.
In the process of flexible pipes, it is necessary to monitor its degree of heating. Excess recalculation is unacceptable; If it still happened, you need to cool a bit of the workpiece naturally.
When the bending is completed, the plugs are dying. If they are sitting too tightly, the plugs are burned with a gas burner.
The hot method of flexing the profile pipe is quite suitable for realization at home. However, it is better to apply it in cases where the element needs to give a single bend. Repeated heating of the pipe entails the loss of metal strength.
Pipe bending with a grinder and welding machine
Press the profile pipe required curvilinear form own hands It is possible with the participation of the grinder, accompanied by a welding machine. For this, on the outlined area, cuts are made across the element that do not reach the end. Then the pipe bends under the desired radius, and the spookils are brewed. The final product will retain a fairly aesthetic appearance (for this it will be quite thoroughly gluing welds) without loss of strength indicators. The only limitation is the outer covering should not have too significant weight. For the equipment of the same greenhouses or canopies with awning coating, this method of obtaining bending can become an ideal choice. The advantage of the technique is that the profile can be bent with any degree of curvature, which other methods usually do not allow.
How to bend profile hands
Finally, we note: bending the profile with hands, in the absence of pipe bending, has been washed only if it is scheduled to bend a small number of items. When many blanks are subject to processing, it is better to still spend a little and buy an appropriate device: it will significantly reduce the consumption of the time and forces of the wizard. In the same way, if only one element is required with a bend, it makes sense to think about its purchase - in a special consumption, it will not introduce you, but will save from a variety of hassle.
Look at the video on this topic:
With the decision of the issue, how to bend a profile pipe at home without pipe bender, you have to face most owners of cottages, cottages and private houses. Desire is presentable and originally equipped outdoor territory leads to the need to create arched structures. These are canopies, gazebos, visors and greenhouses for cellular polycarbonate. Purchase of factory products is associated with costs that can be avoided by bending steel own forces. For this, there are enough tools and materials available in each workshop.
Metal rental having a rectangular cross section is convenient in operation, blanks can be shown under various corners. Difficulties arise when there is a need to make a curvilinear form design items. This is due to the fact that outdoor wall The products acts the strength of the stretch, and the inner side is exposed to compression.
Attempts to bend profile tube without pipe bender are conjugate with such problems:
Avoid such complications is not difficult. It is enough to approach the case competently and thoughtfully.
Dacha owners often have to think how to bend a profile tube for greenhouses quickly, without spending money on professional equipment. Even if presence financial resources It is not always possible to immediately find arcs of the desired form and size.
You can use one of the proposed methods:
In the presence of time and creative approach, non-standard approaches can be applied.
In order for the flexible profile pipes by the radius brought the desired results, it is necessary to take into account such factors as:
There are the following alternative ways of bending rectangular pipes:
To reduce the likelihood of deformation of the walls of the product, it can be inserted into it a thin and long steel spring. In the case when heating is used, it should not be cooled with hot steel with water. From this it can be covered with cracks or burst. It is better to take advantage of the work. When using the muscular force on the free end of the link, it is recommended to plant a long and durable lever. So it will be possible to achieve the desired goal with less effort.
To bend profile pipe with your own hands, you need to have such devices and equipment:
To achieve the exact result, it is recommended to use a special tool. The conductor is a device for accurate calculation and cutting the parts of the parts. The mechanism is used to make marking at the ends of the arches, stops, shusin and cross. Thanks to the use of conductor, welding seams turns out to be smooth and neat.
Canopy is needed almost on any plot: it a good place To accommodate the car, it will be useful for the creation of mini-greenhouse, recreation area, etc. The design of the canopy most often assumes the construction of a frame of profile pipes: they have a small weight and have a large bearing ability.
However, they are quite difficult to be bend to give the desired form, so it is difficult to create arched and other complex structures with their help. How to bend a profile pipe at home?
Options, how to bend a profile pipe for a canopy, quite a lot, but in most cases the use of special tools or equipment is required. Consider in more detail several basic ways:
Important! With this method, it is impossible to allow metal overheating. At the same time, the scale will appear, which reduces the strength of the metal structure.
This method is generally not applicable to galvanized pipes, since the zinc coating will simply burn, and the steel will be defenseless before corrosion. Such a frame cannot be installed: it quickly rusts and can collapse at any time.
Each of the listed ways has the pros, and cons: bending profile pipes in any case, it is very careful, counting radius. Metal is not designed for multiple bending, so such work is desirable to finish at a time.
If you have to hold it again, the pipe can simply break, in any case the carrying capacity of such a frame will be much lower. Since the handicraft methods are much less reliable, it is better to use the pipe bend.
How to bend profile pipe with semicircle? To give it the desired form, you can use various models of pipe bending machines and hand tools. Their use is beneficial for several reasons:
Copper pipes bend much easier than steel, so you can use for them hand tools. Pipe bender with roller mechanism is used to work with profile pipes: it was specifically designed for such tasks and is the most convenient option.
The most common model of the machine of this type is "PG-1": the three rollers installed on the bed make it possible to bend the pipe of the square section to the state of the total ring.
The pipe bender "PG-2" costs almost one and a half times more expensive, such a machine is designed for pipes of larger section and more solid metals. The powerful design makes it possible to bend pipes whose profile is 30 by 60 mm.
How to bend a pipe for a canopy if neither the welding machine nor modern pipe benders are not available? There are several methods of bending, which can be carried out in the usual workshop. Although they do not boast increased accuracySome skill and folk savings make it possible to get a good result.
Such methods always give only a relative result. On the machine the result will be more accurate, and homework depends largely only on the master's experience. Handicraft methods are suitable for creating conventional frames for greenhouses and greenhouses, but in the construction of complex engineering structures, they may be useless.
Purchase stationary factory pipe bending can afford not all, but you can easily use the services of specialists in this area. If you need to bend the pipes, it is better to entrust this work to those skilled in the art, to not doubt the strength of the carrier frame.
Profile pipes make it possible to embody various building projects and interesting solutions, and properly made bends allow you to build canopies and others frame extensions With curvilinear elements.
If I. independent arrangement Private house or cottage almost every developer once faces the need to perform bending of pipes. On how to bend a profile pipe at home, many are thinking about the construction of greenhouses, arbors and other buildings of this type.
And it is not surprising if you consider that profile pipes look markedly advantageous in comparison with ordinary round-section products.
However, if the pipe with round cross section You can be bent ordinary pipe bend, then the profile bend with it will not succeed, because in conventional hydraulic pipe bending rollers and shoes have a folding form that when trying to bend the profile pipe will lead to the appearance of cracks on it, the fuses or pipe simply flattened.
How to bend profile pipe yourself in this case, avoiding her damage? For this purpose, several ways are used, one of which is flexible by means of special machines that are designed just for profile pipes.
Machines of this type are called profilegiles. However, the cost of such machines is very decent, and why the ordinary homeowner professional equipment?
If the professional promotion is not constantly being bend, and from time to time, you can find on sale manual pipe bending, suitable for both specialized and "round" pipes, which are not so expensive - about $ 100. At the same time, it should be borne in mind that in the process, the manual tube will need an application of considerable physical effort.
With a single need to break the profile pipe it is inappropriate to acquire the tool and better contact the workshop or the workshop of the corresponding profile, which will provide the necessary service for reasonable money, or sell the ready-made product.
This option will allow to save and time, and money, while the result of solving the issue will be exactly the one that is necessary - the bending of the profile pipe for the desired radius.
Another method that is often practiced in such cases is to bend profile pipe with your own hands with help, so to speak, folk remedies. However, in such a way it is possible to bend pipes of small sections - steel, copper, polymeric.
How to bend the pipe profile itself? This should be done, based on the size of its section, the thickness of the walls, the material from which it is made, as well as the bend radius.
In addition, the production conditions should be taken into account, the desired fold accuracy and the quality of the product obtained as a result.
The bending of profile pipes is carried out within the limits of technical tolerances in the thickness of the walls and the size of the section. It is worthwhile to avoid such undesirable phenomena, as festers on the inner part of the flexible pipe and flattening its cross-section.
Before you break the square tube for a small radius, you need to remember that it is closer to the ends, because in the middle part the pipe will be more difficult to succumb.
To perform a bend, the pipe bender is required specifically designed for flexible with a cold method. The stretching with the help of such an instrument will lead to a displacement of the neutral axis of the pipe in the direction of bending, which reduces the likelihood of obtaining a corrugated surface on bend.
Being in the machine, the pipe is wrapped around the edges and stretched, and simultaneously with this, it bends when the bending template is moving.
How to bend a stainless steel pipe without loss of pipe quality? In order to prevent the loss of the resistance of the walls of the pipe on bending, the bending is carried out under the inner hydrostatic pressure: they put the plugs to the ends of the pipe and the liquid is supplied inside, after which the bending pattern is fed to the middle of the pipe, with which the bend is performed, giving the pipe the desired form.
The profile tube can be bent with their own hands and without the help of special machines and tools. Moreover, in most cases, it is possible to achieve a bend of really good quality.
Before you bend the profile tube, you will need to arm yourself with a grinder and a conventional welding machine.
Bending is performed in the following sequence:
In this way, an impressive external result can be achieved with the desired bending radius of the pipe.
One such means can be a specially manufactured spring. Before you bend the profile pipe, from steel wire with a thickness of 1-4 mm (depending on the thickness of the pipe), the spring of the square section is poured.
The magnitude of each side of the spring segment should be 1.5-2 mm less internal pipe cross sections so that the spring can be sown without any effort to escape the pipe.
After installing the pipe in the place of the alleged bend, immediately before you bend the profile pipe, the bending area is heated by a soldering lamp. Next, bending pipes on a blank, the radius of which is equal to the desired inner radius of the bending pipe.
If necessary, bend in winterA multiple original method can be applied.
So how to heat the pipe profile:
Dural and brass pipes can be bending in the same way.
How to bend professional without pipe bend? Prepare several buckets of dry and clean sand. If it was not possible to get pure sand, and the usual, lariped in the courtyard.
It will be necessary to sift and how to dry, leaning it on the fire or with the help of a gas burner until the sand stops to soar and smoke. After processing and cooling, sand is referred to in a dry and clean container.
Before you bend the square tube, a wooden wedge to a depth 10-20 cm is clogged with one of the sides, and then pour into the free hole of the pipe prepared clean and dry sand until full filling the pipe. Next clog the similar wedge on the other side of the pipe and begin, directly, the process of bending.
The operation, as in the previous cases, is made using a diameter dweller, corresponding to the desired internal bend radius. If the bending is too cool (small radius), the fold of the bend can be heated using the burner. Sand, tightly scored in the pipe, will not let her lose the integrity or strongly deformed.
At the end of the flexible flexible, one of the traffic jams are burned on the fire, removed from the tube sand and knock out or burn out the second tube from the pipe. Time to be flexible in such a way will take much more, in comparison with how to break the profile tube with the help of pipe bend.
The methods presented in the article will be effective in fulfilling all the conditions listed, but the bend of really high quality in all senses of the word can be achieved by using the help of professionals that work on a specially intended equipment. Come to work with knowledge, only due to this will be able to achieve the desired result, while spending the minimum of funds and efforts.
