Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal bending, in particular to a sheet metal bending and forming machine for a protective panel. Background Technique

[0002] In modern manufacturing, as an important industrial component, the quality and precision of the protective panel directly affect the performance and appearance of various equipment and products. Sheet metal bending and forming is one of the key processes for manufacturing the protective panel, and the sheet metal bending and forming machine is the core equipment to realize this process.

[0003] In the prior art, the common sheet metal bending and forming machines have obvious limitations. On the one hand, it is difficult for the common sheet metal bending and forming machines to adjust the bending width. In actual production, different protective panels often require different bending widths to meet specific design requirements, but most of the existing forming machines perform poorly in this regard and cannot flexibly adapt to the needs of different sizes, which limits their application in diversified production. On the other hand, the adjustment methods of some bending and forming machines that can adjust the bending width are complex. These forming machines may need to rely on cumbersome mechanical structures or complex control systems to adjust the width, which not only increases the operation difficulty but also reduces the production efficiency. Operators need to undergo special training to master these complex adjustment methods, and it is easy to make mistakes during the adjustment process, affecting the product quality. Therefore, we propose a sheet metal bending and forming machine for a protective panel to solve the above problems. Content of the Utility Model
