Torsion shaft synchronous four-roller plate bending machine

Technical Field

The invention relates to the field of plate bending machines, in particular to a torsion shaft synchronous four-roller plate bending machine.

Background

The plate bending machine is a device for bending and forming a plate by using a working roll, can form parts in different shapes such as a cylindrical part, a conical part and the like, is very important processing equipment, and has the working principle that the working roll is moved under the action of external force such as hydraulic pressure, mechanical force and the like, so that the plate is bent or rolled and formed. According to the rotary motion and position change of the working rollers with different shapes, parts such as elliptical parts, arc parts, cylindrical parts and the like can be processed. However, because the roller movement is asynchronous, the machined part has defects, and therefore, a plate bending machine capable of solving the problems needs to be developed.
