Description

Technical Field

[0001] This utility model relates to the field of plate rolling machine technology, specifically to a support structure for a fixed roller of a plate rolling machine. Background Technology

[0002] A plate rolling machine is a device that uses work rollers to bend sheet metal into various shapes, such as cylindrical and conical parts. It is a very important processing equipment. The working principle of a plate rolling machine is that external forces such as hydraulic pressure and mechanical force cause the work rollers to move, thereby bending or rolling the sheet metal into shape. Depending on the rotational movement and positional changes of the work rollers, elliptical, arc-shaped, and cylindrical parts can be processed.

[0003] A four-roll plate bending machine is generally equipped with one fixed roll, one movable roll, and two side rolls. One end of the fixed roll is rotatably connected to the fixed roll mounting seat of the upright, and the other end is supported by a flap plate. Currently, the fixed roll mounting seat is directly installed on the outer end of the corresponding upright, which can easily lead to a decrease in stability after long-term use, thus affecting the stability of the fixed roll. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Summary of the Invention
