[0002] The plate rolling machine is a device that uses working rollers to bend and shape sheet materials. It can form parts of different shapes such as cylindrical parts and conical parts. It is a very important processing equipment. The working principle of the plate rolling machine is to move the working rollers through external forces such as hydraulic pressure and mechanical force, thereby pressing or rolling the sheet metal into shape.

[0003] The mechanical three-roller symmetrical plate rolling machine is a three-roller symmetrical type. The upper roller performs vertical lifting and lowering motion at the central symmetrical position of the two lower rollers, which is obtained by the screw nut worm gear transmission. The two lower rollers perform rotational motion, which is driven by the motor. The output gear of the reducer is meshed with the gear of the lower roller to provide torque for the rolled plate. The existing mechanical three-roller symmetrical plate rolling machine processes the plate manually by placing it between the upper and lower rollers during processing, lacks a limit device to correct the plate, and the plate is prone to offset during the processing, thereby reducing the bending quality of the plate. Therefore, a technical measure is proposed to solve the problem that the existing mechanical three-roller symmetrical plate rolling machine processes the plate manually by placing it between the upper and lower rollers during processing, lacks a limit device to correct the plate, and the plate is prone to offset during the processing, thereby reducing the bending quality of the plate.
