Features

The bending machine has 4 rolls. The upper roll uses a mechanical transmission, while the bottom and side rolls use lift hydraulic driving. The system features an electric centralized operation system.
The bending machine is designed with a pre-bending function, both end of metal plate can be pre-bended, and cylindrical workpiece, arc workpiece and tapered workpiece with a certain tapering range can also be rolled on this plate rolling machine through one time feeding process. Metal plate ends can be pre-bended with a minimized residual rectangularity, featuring high work efficiency. Besides, the plate bender has ability for rough leveling on metal plate.
