The model 4 CNC pipe bending machine adopts two power sources, namely, servo motor and compressed air, to drive the equipment to realize high-speed and accurate digital control of pipe bending.
The disassembly actions of the machine include clamping, bending, core pulling, feeding and pipe turning.
Action flow of full-automatic bending:
    Clamping pipe fittings (air driven, including two pipe clamping actions of main clamp and guide clamp);
    Elbow (driven by servo motor, elbow is driven by planetary reducer and spiral bevel gear drive);
    Feeding (driven by servo motor and driven by grinding ball screw for pipe feeding and positioning);
    Rotating pipe (driven by servo motor, using planetary reducer and sprocket chain drive to rotate and position pipe fittings);
    Core pulling (air driven, used for bending of thin-wall and small radius pipe fittings, optional closing);
