[0002] A pipe bender is a mechanical device used for pipe bending. It can automatically complete the pipe bending operation without manual operation, thereby greatly improving work efficiency, saving time and labor costs. With the advancement of technology, people's requirements for pipe bender are getting higher and higher.

[0003] Since the pipe bending machine still requires the user to observe and determine the bending angle requirements of the pipe during actual operation, and when bending processing is required at multiple positions, the user is also required to move and adjust the bending position of the pipe product, which leads to low applicability of the device and can no longer meet people's needs. Therefore, we propose a new type of pipe bending machine that is easy to form quickly to solve the above-mentioned problems. Utility Model Content
