About 50 common bending machine adopts three power sources of servo motor, compressed air and hydraulic pressure to drive the equipment to realize high-speed and accurate digital control of bending forming.
The disassembly actions of this machine include: clamping, bending, core pulling, feeding, pipe turning, mold moving, mold changing, and trusteeship.
Action flow of full-automatic bending:
1. Clamping (driven by servo motor, including two tube clamping actions of main clamp and guide clamp);
2. Elbow (driven by servo motor, the precision RV Reducer is directly connected to the elbow spindle, and the elbow precision is high);
3. Feeding (driven by servo motor, planetary reducer and gear rack drive for pipe feeding and positioning);
4. Rotating pipe (driven by servo motor, the space angle between two bending arc planes is positioned during continuous bending);
5. Mold shifting (driven by servo motor, used for switching between left and right bending directions);
6. Mold change (driven by servo motor, switching between mold layers can be realized when multiple sets of bending molds are installed at the same time)
7. Core pulling (hydraulic drive, used when bending thin-wall and small radius pipe fittings, can be closed);
8. Trusteeship (lift the longer pipe fitting to avoid the pipe fitting sagging and falling away from the wheel model cavity).
