Despite the great variety of metal products, which are presented on the market, among them are the following, which are the most common. Greenhouses should be included here, canopies, gazebos, furniture sets. To create these structures, you can use machines for bending profile pipes, made with their own hands.
Of course, when there is a need to give a pipe the desired shape, you can use the tools at hand. But in this case it is impossible to achieve high quality of the finished product. That the detail had the most exact geometrical characteristics, a specialized machine must be used.
Technology of bending of profile pipes
A characteristic feature of each metal product is the presence of a certain hardness and strength. To give a metal rod or profile pipe a certain configuration, it is necessary to make an effort, thanks to which the workpiece will be able to take one or another geometric shape. And for the effective decision of this problem it is necessary to apply the special mechanism, better known among experts as a machine for bending pipes.
If we talk about the purpose of such equipment, then it is to perform a gentle deformation of the workpiece.
To replace the original shape of the part required, some effort is needed, which can be done manually or using an electric motor. As a mechanical device, which can simplify the task of bending a metal product, a pneumatic or hydraulic press can also act. The following types of pipe bending machines are the most widespread in the industry:
- with manual drive;
- with electric drive.
To get a better idea of the design of the machine for bending profile pipes, it is best to find drawings, where all its constituent elements are given. If you want and have certain skills, this equipment can be made yourself. However, it should be borne in mind, that such equipment will demonstrate a low level of performance.
The most common pipe benders of the simplest design were in the structures of housing and communal services. Enterprises, specializing in mass production, usually resort to models of pipe benders, equipped with electric drive. Every product created with the help of such a machine must meet all the requirements of standards and technical conditions..
Each time, when you have to make a new product, it is mandatory to adjust the machine for bending profile pipes. If we talk in more detail about this procedure, then it includes the following steps.
- First you need to insert a template into the pipe bender, has geometric shapes of the created product.
- After that are engaged in adjustment of all working knots of the pipe-bending equipment.
- After finishing work with the adjustment of the pipe bender, begin to bend several samples of the product, and then compare them with the template.
- When you have to deal with a large number of blanks, then it is necessary to make a reconciliation of finished products for that, that they have the necessary parameters. If there are serious deviations between the finished product and the template, then you have to re-adjust the pipe bending equipment.
Machine design
There are plenty of videos online, which allow to get acquainted with features of work of pipe-bending units with the electric drive. And regardless of the design of the equipment it uses the same kinematic scheme of the mechanism. This point must be taken into account, if you decide to make a pipe bending machine with your own hands. And best of all, if you make your own drawings for the future machine.
A feature of homemade machines is that, that when using them are quite common situations, when the workpieces are flattened. This leads to fractures in the bending area. Blanks, who have similar defects, no longer suitable for use.
However, everyone can avoid such unpleasant results. You can achieve this, if at the initial stage the technology of bending on profile pipes will be worked out, having different cross sections. Based on practical experience, then there are enough people today, who are interested in profile pipe bending services. First of all, this should include the owners of dachas, who often have to build greenhouses with their own hands. You can provide such a service only if, that the entrepreneur will solve the issue with the main component, without which it is impossible to provide them to buy a pipe bending machine.
That the elective equipment most effectively solved the problem of bending products, the following parameters should be considered:
- version of execution, which can be portable or stationary;
- management, which can be automatic or manual;
- drive type, which is manual and electric.
If we talk about the price of a model, then the focus should be on options, which are provided in the choice of the device. If the buyer is not interested in high precision products, then it may well be limited to the purchase of the machine, having a simple design. There may also be an alternative - making a pipe bender with your own hands.
We make the machine with our own hands
If you are considering making a pipe bender with your own hands, then the first, what you need to do - read the drawing of the device.
The following elements can be distinguished in the design of such a device:
- bed;
- transporter;
- bracket with guide corners;
- top roller;
- clamp.
Assembly of these components is carried out separately, and at the end of this work proceed directly to the assembly of the machine as a whole. Even before the beginning of production of the machine for bending of pipes it is necessary to take care of existence of materials necessary for the machine, parts and appliances. You will be able to perform work on production of a pipe bender, if you have a welding machine and a set of tools. First you need to prepare all the basic elements, then begin work on their assembly in a certain sequence.
Bed assembly
The frame is an element, having the appearance of an ordinary table or machine. For information on required materials and components, from which this device is assembled, should look in the specification.
You can use a channel or pieces of pipe to make the legs, reaching in diameter 100 mm
If you plan to use welding to connect the main elements, then you should take care of it, that all overall dimensions were observed, which are shown in the drawing. Having finished work on assembly of a bed having been convinced of its reliable fastening, you can proceed to the installation of the conveyor.
Assembly and mounting of the conveyor
The conveyor is a design, in which there are two videos, located on opposite sides of the frame. For high-quality installation, it is necessary to get acquainted with the drawing of the conveyor, where the necessary information is given.
Particular attention should be paid to the sprocket chain on the shafts, which must be firmly and accurately fixed. Next, proceed to the installation of the tensioning mechanism, in the design of which also provides a similar star. The function of this part is to select the optimal level of tension of the drive chain.
Assembly of the clamping mechanism
You can usually choose a simple clamp for the role of the clamping mechanism. And here it is important to rely on data, which are shown in the drawing. For this element to function properly, it is necessary to observe all sizes.
If certain deviations are detected, the degree of clamping will be as follows, that it will no longer be possible to guarantee the required accuracy in the manufacture of products. A similar approach should be followed when installing rollers. When all operations on assembly of the clamping mechanism will be executed, it is necessary to be convinced of serviceability of the equipment, having tried it in acceptable modes.
Pipes of different diameters must be used for such tests. The bending operation itself is performed according to pre-calculated parameters.
Particular attention should be paid to this, that between the received results and the calculated geometrical sizes of deviations were not observed. If we talk about homemade pipe bender, then such a machine can be used to process not only ordinary round pipes, but also profile products. If you decide to make pipe bending equipment, to use it to regularly fulfill many orders, then you should take care of drawing up instructions with the rules of its maintenance.
Operation and maintenance of the machine
Pipe bending equipment of manual version differs in that, that it is very easy to work on and at the same time in the course of its operation malfunctions seldom arise. But, despite this, nevertheless it is necessary to check regularly serviceability of its components and to avoid influence from aggressive factors of environment.
The greatest threat to it is precipitation. First of all it is necessary to protect rolled rollers from contact with moisture, as this threatens the formation of rust. To solve this problem, you can use a tarpaulin shelter.
If at first the variant with creation of a portable pipe bender was considered, then a dry place should be used as storage space. After finishing work on bending profile pipes, the machine must be put in order, remove dust from its working units, dirt and sand. To stationary machines for bending profile pipes, equipped with electric drive, could demonstrate high productivity and efficiency for a long time, they need to provide regular maintenance and prevention.
Conclusion
The machine for bending profile pipes is an effective device, by means of which it is possible to give quickly and without special efforts to any metal preparations the necessary form. And you don't have to buy a ready-made pipe bender to do this. Possessing the necessary skills, each owner can make such a machine with his own hands. Having at hand a drawing of each component, it is possible to make the machine for bending of pipes, which will demonstrate high performance.
Keep that in mind, that the pipe bending machine needs special attention. Maintenance is one of the important activities, the correct carrying out of which will provide long service life of the machine. To do this, you need to take care of it, to minimize the interaction of pipe bending equipment with negative factors, which can reduce the service life of certain working units of the machine. Adherence to such recommendations will allow the pipe bending machine for many years to properly perform its function of deformation of metal products.
