[0002] In the field of automobile manufacturing, the pipe bender is the key equipment for processing fuel pipeline, brake oil pipe, air conditioning pipeline and other metal pipes, and its core function is to accurately bend the pipe through mechanical force, so that the pipe forms a specific arc and angle that meets the vehicle structure layout. The traditional pipe bender usually uses a feeding mechanism to push the pipe to the bending station, and a clamping and fixing mechanism is used to position the pipe, and then the bending action is completed through a mold.

The contact surface of the clamping block and the pipe is prone to lateral extrusion force. Especially for pipes with large length and multiple segmented bending, the lateral force will cause the pipe axis to deviate from the initial alignment reference of the feeding mechanism and the bending mold during repeated clamping and feeding process, not only reducing the consistency of the bending angle, but also possibly causing surface indentation and plastic deformation due to local stress concentration of the pipe. In addition, the traditional clamping mechanism has poor adaptability to pipe diameter specifications. When switching to different size pipes, the position of the clamping block needs to be adjusted, which is tedious and difficult to ensure the coaxiality of the clamping center and the bending center, further affecting the processing precision.
