Bending copper and other materials , which are used for the manufacture of pipes

methods tube bending

Technology bending tubes of different materials suggests two ways to accomplish this task:

• hot pipe bending;
• cold deformation.

From school physics course we all know that the product is better heated takes a bent shape than cold.Therefore, in this way the pipe can be bent in any material.

The second way - "cold", is used for plastic materials, such as copper and its alloys.Let us examine each process separately.

process cold bending pipes

Make Bending pipes without heating the product, can be either manually or by mechanical devices.

In manual deformation possible use of the two options:

• tube deformation in the bearings;
• winding onto template.

If bent pipe on supports perform the following steps:

• stifle the product in two supports, so that the land was for the strain between them;
• after clumping hammer or a sledgehammer through the pad to give the pipe the desired shape.

This method can be implemented in a flexible stainless steel pipes, but this method is not desirable, and is applicable if there is no bending tool, since the bent portion does not always work smooth and neat hand.

manner winding tubes on a template can be made of flexible copper, polypropylene and steel products.Carry out this process as follows:

• to start a pipe filled with sand, salt water or non-viable in order not to change the profile of a bent pipe;
• then the product is wound onto a template or gauge, clamping pipe ends in the device.

In this way, spent quite a long length of pipe as large lever must be used for bending.

Bending pipes of large diameter and made of durable material (eg stainless steel) is easiest to mechanically on stationary machines.

mechanical pipe bending

Ways mechanical deformation of the pipes are only two:

• first - running pipe;
• second - hydraulic running.

This use hand and power tools.

When the deformation of the running process, the pipe is installed in the machine and fed to the bending portion of the deforming roller.With the help of an electric motor or manual crank start to rotate the drum and push the shaft to the pipe.The greater the force with which the press to warp, and the greater the radius of the bend.With this method, you can bend copper, polypropylene and stainless steel pipes of small diameter, but quite efficiently and quickly.And in order to carry out the bending of large diameter pipes, using a press or gidrodeformirovanie.

In this way, the product is bent under the pressure of the liquid (water or oil) on a special gauge or template.In addition, the hydraulic deformation allows bending not only a pipe but also change their diameter.

process hot pipe bending

hot deformation method can be bent steel pipes of any hardness.The options for this process are also two: manual and mechanical bending.

Manual hot deformation is performed as well as cold, just before work station for bending heated torch or a blowtorch.The same thing happens when you change the mechanical profile - before feeding the machine or press the pipe is heated.
