A plate rolling machine is a device that uses work rolls to bend and shape sheet metal, and can form different shapes of parts such as cylindrical and conical parts. It is a very important processing equipment. The working principle of a plate bending machine is to use external forces such as hydraulic pressure and mechanical force to move the working rollers, thereby bending or forming the sheet metal. Based on the rotational motion and positional changes of work rolls of different shapes, elliptical, arc-shaped, cylindrical and other parts can be processed.
