with the work roll bending sheet, and then form a shape, can form cylindrical parts, conical parts and other different shapes of parts, is a very important processing equipment.The working principle of the plate rolling machine is through the action of external forces such as hydraulic pressure and mechanical force to move the work roll, so that the plate bending or bending forming.According to the rotating motion and position change of the work roller of different shapes, the elliptic parts, arc-shaped parts, cylindrical parts and other parts can be processed.
