Description

Technical Field

[0001] This utility model relates to the field of bending processing of thin steel plate parts, specifically, it relates to a thin steel plate bending fixture. Background Technology

[0002] Steel plates are flat steel products made by pouring molten steel, cooling, and pressing. They are flat, rectangular, and can be directly rolled or cut from wide steel strips. Steel plates are classified by thickness into thin steel plates, medium-thick steel plates, and extra-thick steel plates. Thin steel plates are approximately 4 mm thick, with the thinnest being 0.2 mm; medium-thick steel plates range from 4-60 mm; and extra-thick steel plates range from 60-115 mm. In the production of thin steel plate parts, cutting and bending processes are usually required. Currently, many devices are used for bending thin steel plates, such as the steel plate bending machine disclosed in Chinese patent CN220426403U. However, this steel plate bending machine requires additional support frames to support the steel plate during bending. Before bending, the support frames need to be moved according to the steel plate specifications and bending requirements, making the process relatively cumbersome.

[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content
