We offer a machine for bending profile pipes

Profile pipes are used for the production of various structures and objects: greenhouses, canopies, arbors, furniture sets, and all this can be done with a machine for bending profile pipes with their own hands.

If necessary, any pipe can be bent using improvised tools. However, the quality of such a product will be a priori low.

It is possible to manufacture a part with exact geometric parameters only on the machine.

Profile bending technology

All metal products have hardness and strength.

For bending a metal rod or profile pipe, it is necessary to apply forces that are capable of changing the geometric shape of the initial workpiece.

This operation can only be carried out using a special mechanism, which is called a bending machine.

The main function of the machine is to ensure a gentle deformation of the workpiece. This deformation is carried out by the efforts made by the worker or electric motor.

Along with the electric drive, the machine design uses a pneumatic or hydraulic press.

Today, the enterprises use two types of pipe bending machines:

  • with manual drive;
  • with electric drive.

The drawing of the simplest device for bending profile pipes is shown below. Such a machine can be made with certain skills with your own hands. The performance of such a device will be low.

Hand bender

The simplest pipe benders are used in the structures of housing and communal services.

The enterprises which are engaged in serial production of production, are equipped with bending machines on an electric drive.

Here, the final products meet the stringent requirements of standards and specifications.

When you start to release the next product, you need to re-configure the equipment. In this case - the unit for bending the profile pipe. You need to do this in the following way.

First, a template is installed in the machine, which corresponds to the geometric shapes of the future product. Then all the elements of the machine are adjusted.

After configuration, it is necessary to "bend" several instances of the product and compare it with the template.

In the process of manufacturing a large batch of products, the sampling should be periodically carried out to meet the specified parameters.

If the deviations from the template are considerable, the machine setting is made anew.

When we are making this machine with our own hands, we must remember this. The drawing of the machine is preferable to make independently.

When operating a self-made machine, the pipes are often flattened. In the place of bending, creases are formed. For further use, such products are not suitable.

To prevent similar results in the future, it is necessary to work out the bending technology on the profile pipes of different sections at the initial stage.

Everyday practice shows that the service of bending of a profile pipe is in demand with a certain category of the population. In particular, the summer residents, who build greenhouses with their own hands.

To provide this service, entrepreneurs prefer to purchase a bending machine.

When choosing the following features of the machine:

  • portable or stationary;
  • with automatic control or with manual;
  • with manual drive or with electric.

The cost of a particular model is determined by the options that the unit is equipped with. If high precision of products is not required, you can purchase a simpler design or make a bender yourself.

Machine with your own hands

When making a decision to make a pipe bender with your own hands, you need to study the drawing of the device in detail.

The unit consists of the following units:

  1. frame;
  2. conveyor;
  3. bracket with guide corners;
  4. upper roller;
  5. clamp.

Each assembly is assembled separately, after which the machine is assembled as a whole.

Before starting to manufacture, it is necessary to prepare all materials, parts and devices from which the machine is completed.

For work you will need a welding machine and a tool kit. The first step prepares all the basic elements, and then assembles them in a certain sequence.

Assembling the

frame The molded frame is a conventional table or workbench. Source materials and component parts are specified in the specification.

As legs, you can take a channel or use pipe lengths with a diameter of 100 mm.

When assembling, which is performed by welding, you must strictly maintain the overall dimensions specified in the drawing.

After the frame has been assembled and fixed, a transporter must be installed on it.

Assembling and fastening the conveyor

The conveyor consists of two rollers which are attached to opposite sides of the frame. The conveyor drawing contains all the necessary data in order to perform the installation.

Homemade machine

It is very important to secure the chain sprockets on the shafts accurately and reliably. The next step is fastening the tensioning mechanism, which also has the same asterisk.

It is designed to regulate the degree of tension of the drive chain.

Assembly of the clamping mechanism

As a clamping mechanism, an ordinary clamp is used. And at this stage it is necessary to be guided by the data specified in the drawing. It is important to maintain all installation dimensions.

If there are any deviations, the degree of clamping will not ensure the proper accuracy in the manufacture of products. Similarly, with the required accuracy, you need to install rolling rollers.

Upon completion of assembly, it is necessary to test the device in acceptable modes.

For this, pipes of different diameters are taken, which must be bent according to predetermined parameters.

It is important that the given geometric dimensions strictly comply with the results obtained.

In this context, it should be noted that the assembled pipe bender can work with both conventional round tubes and profile products.

If the machine is planned to organize regular execution of orders, then you should develop an instruction on the rules of its maintenance.

Operation and maintenance of the

The manual bending machine for profile pipes is simple and trouble-free to use. At the same time, it must be kept in order and protected from the corrosive effects of the environment.

First of all, from the rain and snow. Rust is not allowed on rolling rollers. This can be done with a canvas cover. The portable bender must be stored in a dry place.

After use, the machine is cleaned of dust, dirt and sand. Stationary machines for bending profile pipes with electric drive require regular maintenance and preventive maintenance.

The electric motor must be inspected at least once a year.

Maintenance requires both manual and electric machine. When moving the machine from one object to another, it should be protected from possible damage during loading and unloading.

After installation in a new location, you need to check the quality of the fastening of all components and lubricate the axes of all the rollers. Worn out parts should be changed in time to new ones.

For prolonged storage of the tubing, all unpainted surfaces must be coated with a preservative grease.

With strict adherence to the rules of operation, maintenance and storage, the unit for bending profile pipes will serve for a long time and reliably.
