Manual profile by yourself: drawings, sizes, photos. Rollers for profiling

Many of those who are accustomed to doing household chores with their own hands know that in construction, as in repair, it is simply impossible to do without metal profiles and pipes. Often, you may need to bend these materials, and in accordance with certain shapes and sizes. For such needs, various tools are designed for bending. The ready-made machines on the market are very expensive. In order to save money, you can do a profiling yourself. Such an instrument will certainly help you in the economy, however, first of all, you need to decide whether you really need it. Let's consider the operating principle of this hand-held machine, its variants, we will learn how to make a profile roll with our own hands.

Why do I need a profile?

The list of tasks that this tool can handle is huge. When laying a cable or pipeline for gas and water supply systems, it is likely that the pipes will need to be bent. For such purposes, profile bending is simply indispensable, without it the process of erection will turn into flour. Metal profiles for any construction needs are perfectly deformable with this tool. Different angles, channels and fittings can not resist the onslaught of the profiling in terms of construction and repair tasks. Also bending machines are widely used in the production of various pipes and profiles, whether PVC or steel pipes, copper or aluminum.

The machine, including the profile bending machine, made by its own hands, makes it possible to deform the part without heating it, that is, the principle of cold rolling is used. A very significant advantage is that one roll is needed in order for the part to be ready. With its help you can make a circle, a spiral or other various shapes from a metal workpiece.

Without this tool, at least one large industrial sector is unlikely to manage today: energy, automotive, petrochemicals, and so on. In work on this machine there is nothing intricate, everything happens simply: the part is rolled between the upper and side rollers, which are pressed.

What constructively represents a profile?

This tool can be provided with a mechanical, hydraulic or electric drive. Often performed in a portable version, also has a very compact size and light weight. The kit can include various attachments, making this machine universal for all types of blanks.

Varieties

• Machine with a movable top roller. By design is the simplest, because as the motion is given only one movie. This design allows you to calculate the bending radius of the workpiece with high accuracy, making corrections for the deformation of the metal. Such profile rollers can be called the most popular at the moment.
• Machine with a movable left roller. With this type of machine you can easily perform a spiral bend, while it is able to perform the functions provided by other types of apparatus.
• Machine with movable lower rollers. It is used for bending large parts, because thanks to two movable rollers the force is distributed optimally.
• Machine with all movable rollers. By design, this is the most complex device. Due to the mobility of all the rollers, the capabilities of this machine include the functionality of all types of profile rollers.

How does the device work?

Regardless of whether the profile is made with your own hands or it is factory-made, the main principle of this tool is precisely the rolling of blanks, and not bending. To begin with, the machine is securely attached to the base. If there is such a need, the installation is grounded, and also the reliability of the electrical circuit and the mechanical structure is checked.

The first start is preceded by the removal of the preservative grease with rags. After that, the machine should work in "no-load" mode for about half an hour. The defects that have arisen during this time are eliminated. After this, the parts that are to be folded must be cleaned of oil and debris. The part is located between the shafts, after which the rolling process begins.

Types of profiling: electric

Basically, such devices have large dimensions, therefore, their fixed installation is mandatory. Electric profile rollers have high accuracy, and also do not reduce the strength of parts when rolled.

Hydraulic

Such a system, as a rule, is intended for industry. When installing water supply and sewage systems, such machines are simply irreplaceable. Their main advantage is high speed and ease of operation. But this is not all, what will make you happy with the profiledbig with your own hands. Dimensions of blanks that can be bent by such a machine are very diverse.

Manual

This type is considered the most budgetary. Due to its compactness, it is possible to carry such a hand-made profile manually. The drawings of such a machine do not include any foundation. True, working with such an instrument is not very easy. First, the bending process requires a lot of effort from the user, and secondly, the work process is not fast. The disadvantage is also the inability of a manual device to bend thick pipes, as well as low accuracy.

Be that as it may, this type is the most suitable option for household chores. After all, the amount of work during the repair does not imply a huge scale, so manual machines will be able to do this work.

Varieties of hand-held machines

There are several options that allow you to make a hand-made profile manually. The first version is the most popular. In such machines, moving rollers act on the workpiece, and as a result, bending occurs. The workpiece bends against the fixed part of the machine.

The next option is a device in which the frame moves towards the workpiece. The advantage of these devices is the fact that thanks to a special design, they are very easy to use, and also when they are used, the workpiece is not crushed.

For working with thick sections, it is best to use a hydraulic manual profiler by yourself. Thanks to the pressure created by hydraulics of tens of tons, there is no difficulty in working with such details.

How to make a profiling yourself

As already noted above, for those who work in the construction industry, the best option is to have a functional stationary device. If the amount of work is small, and you need a home repair assistant, then you can make a hand-made profile manually.

Dimensions, as well as design, are chosen for the size of the blanks. For pipes up to 20 mm in diameter, a simple construction can be made: iron pins fixed to the base. For bending, it is necessary to place the workpiece between the pins and apply the force to the desired direction. If it is necessary to deform thicker pipes, it will be necessary to produce a more powerful profile roll with your own hands. The drawings and design of such a device will be somewhat more complicated. But you can still manage.

You will need rollers for profiling. With their own hands, they are made with a circular cross-section, which will need to be installed on the base. The radius of the roller should coincide with the radius of the workpiece. The ends of the pipe located between the rollers on one side are fixed to the winch, on the other hand they are fixed on the base. When the winch is activated, the workpiece will bend.

Let's consider one more method, as it is possible to make a simple profile roll with your own hands. The first step is to prepare a cement slurry. Mixing cement and sand in proportions of one to four. Next, you need to place on the area with a gravel cushion the eightieth pipe segments. From each other they should be at a distance of 50 mm. After this, the solution should be poured, making sure that the pipe pieces are in an upright position. Before the solution is completely dry, all further work is suspended.

In order to avoid undesirable cracks and buckling during work, the pipe-workpiece is filled with quartz sand. On the one hand, it must be plugged with a wooden conical stopper with holes for the output of the gases that form. After this, it is necessary to heat the pipe to a dark cherry hue. After the workpiece has cooled, sand should be left with the remaining space. In order not to form voids, it is recommended that the hammer periodically tap the pipe.

Recommendations for bending the workpiece as a function of heating

• Direct angle - warm-up interval = pipe diameter X 6.
• 60 degrees - warm-up interval = pipe diameter X 4.
• 45 degrees - warm-up interval = pipe diameter X 3.

Heating stops when the scale is completely removed from the workpiece, indicating optimum heating. In the case where there is arcing of the surface of the part, it can be concluded that the workpiece is overheated. Pipes are bent into one set, otherwise the structure of the metal can be broken.

The machine, designed for hot bending of parts, must be provided with a template, the absence of which entails some difficulties in the work. In addition, do not ignore the security rules. For example, it is forbidden to be in front of a wooden plug during the deformation process of the pipe. After the pipe is deformed by the hot method, it remains to remove the cork and sand from it. It is worth noting the popularity, which received such a profile. Draw your own drawings will have to be. Otherwise, the accuracy of the design will be distorted. It will be useful to fix and theoretical information on how to make a profile roll with your own hands. Photos and information about this are available in our article.

Disadvantages of self-made machine tools

• The difficulty in minimizing the bend radius of the billet.
• Limited in the radius of the bend.
• The work on such machines is very complex, so doing a large amount of work is simply not practical.
• Difficulty in bending pipes and blanks with a large cross section.
• The difficulty in changing the shape at different parts of the workpiece.

If there is a need to work with parts that have a small cross-section, you can do with a simple profile bender consisting of two pins and a base. When deformation of thicker parts, one should pay close attention to their design features. Particular attention is required for working with pipes, because for them there is a dependence of the maximum allowable bend radius from the wall thickness. In free access, you can find special memorable tables for selecting the maximum radius.

Despite the fact that the process of manufacturing a machine with their own hands may seem too complicated and scare many, saving in comparison with the purchase of a finished product can reach several tens of thousands of rubles. This argument in favor of self-made profile can be called very weighty.
