The CNC pipe bending machine adopts two power sources, servo motor and hydraulic pressure, to drive the equipment to achieve high-speed and accurate digital control of pipe bending.
The disassembly actions of the machine include clamping, bending, core pulling, feeding, pipe turning, side auxiliary pushing and material supporting.
Action flow of full-automatic bending:
1. Clamping pipe fittings (hydraulic drive, including two pipe clamping actions of main clamp and guide clamp);
2. Elbow (driven by servo motor, elbow action is carried out through planetary /rv reducer and chain drive);
3. Feeding (driven by servo motor, when bending continuously, the linear distance between the two corners is positioned);
4. Rotating pipe (driven by servo motor, the space angle between two bending arc planes is positioned during continuous bending);
5. Core pulling (hydraulic drive, used when bending thin-wall and small radius pipe fittings, can be closed);
6. Support material (lift the longer pipe fitting to avoid the pipe fitting sagging and leaving the wheel model cavity);
7. Side auxiliary pushing (controlled by oil cylinder, carried out simultaneously with the bending action, and assisted the forming of pipe fittings).
