The device can pre-bend the edge of plate,feel steel plate just one time,don’t need to return pre-bend the sides of the plate,and roll the plate. The up-roller is the main drive roller,the down rollers and side roller use hydraulic drive to do elevate movement. And controlled by computer to up or down, horizontal adjust automatic,show by screen, the synchronization precision attached ±0.2mm. Turnover and resume of flip-bearing used hydraulic to drive. Installed balance system on the ends of up roller, so it’s easy to unload workpiece.
