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.
