Features:
1. It has fast forward, work forward and fast return functions
2. Working principle: both fast approaching and fast returning are operated by the middle oil cylinder. When working, hydraulic oil enters three oil cylinders and pressurizes the workpiece at the same time to ensure pressure balance. When the three cylinders are working, correct the flattening problem of the central part of the common bending machine. The up-down motion balance of the machine adopts the rigid structure of mechanical synchronous shaft, with simple structure and convenient maintenance
3. This machine can solve the problem of large central angle by adjusting the pressure and holding time according to different plate thickness.
