In this process, the groove rotating column 6 is fixedly connected inside the top rectangular groove 5 to provide support; at the same time, the movable rotating block 7 can be freely rotated and supports the pipe through the groove on its top to prevent lateral displacement. Then the top stamping rod 3 starts to descend and exerts force. The connecting stamping roller 4 contacts the pipe and rotates to achieve uniform force application, so that the pipe is subjected to stable stamping effect and deformed to the designed bending angle.
