The working principle of the automatic tube bender is as follows. The elbow cast is fixed to the headstock and wrapped with the headstock. The tube is fixed in the clamping groove of the flat tube elbow mold through the clamping mould, and the movable pressure guide material slider is tightly connected to the tube. Professional advancement and inspection of safety applications for CNC tube bending can prevent or reduce accidental damage that can occur during production. The bending master must maintain a sense of responsibility for safe work in all business responsibilities and must adequately protect his motives. Machines are generally used to teach personnel working environment, machine operation safety, mold equipment consultation, safety equipment and operation methods, important rules of personal safety, and pay attention to personal safety awareness.
