The working principle of a cold bending forming machine is to feed metal sheets into the forming rollers, and through the rotation and compression of the rollers, the sheets are bent into the desired shape. During the processing, it is necessary to adjust the position and spacing of the forming rollers to adapt to the processing of different specifications and shapes of profiles.

Pipe bending machine is a machine equipment used for bending metal pipes, widely used in industrial production, manufacturing, processing, construction and other fields. It can be used to bend straight pipes into various shapes of curved pipes, and parameters such as bending angle, radius, and bending radius can be adjusted according to requirements. The pipe bending machine is mainly composed of a frame, a pipe bending mold, a hydraulic system, an electrical system, etc. Its working principle is to place metal pipes in the conduits of the machine equipment, and heat and bend the pipes through a high-speed rotating mold to achieve bending and forming.
