Operation flow of pipe bender

Operation flow of pipe bender

Today we are going to talk about the operation process of pipe bender. Aocheng Machinery Equipment Co., Ltd. produces medium frequency pipe bender and hydraulic pipe bender.

Regularization of tube shape

Excessive arcs, arbitrary curves, compound bends, and arcs greater than 180° should be avoided when designing and piping.Excessive arc not only makes the tooling bulky, but also restricted by the size of the pipe bender machine tool;Arbitrary curve, compound bend design modeling is very unreasonable, greatly hindered mechanization, automation production, so that the operator is difficult to get rid of heavy physical labor;Arc greater than 180° makes it impossible for the bender to unload the mould.

Bending radius standardization

The bending radius should be as far as possible to achieve "one tube one mode" and "multiple tubes one mode".For a pipe, no matter how many bends there are and how the bending Angle is, the bending radius can only have one, because the pipe bender does not change the module in the bending process, which is "one mold for one pipe".And "multi-tube one mold", that is, the pipe with the same diameter specification should be used as far as possible the same bending radius, that is, the use of the same set of modules bending different shapes of pipe, so as to help reduce the number of modules.

Bending radius

The bending radius of the catheter determines the resistance of the catheter in bending.Generally speaking, the pipe diameter is large, the bending radius is small, the bending is easy to appear wrinkle and skid phenomenon, the bending quality is difficult to guarantee, so the general selection of the R value of the bending die is 2-3 times the pipe diameter as well.

Bending forming speed

The main influence of bending forming speed on forming quality is: the speed is too fast, easy to cause the flat bending part of the pipe, the roundness can not meet the requirements, resulting in the pipe crack, pull off;The speed is too slow, easy to cause the wrinkle of the catheter and the compression block slip, the large diameter of the pipe is easy to form the bending part of the catheter sag.In view of the large number of tests on the two CNC pipe bender, it is appropriate to determine the bending speed of the pipe as 20%-40% of the maximum bending speed of the machine.
