[0002] Metal sheet is a flat product made of metal materials as the main raw material. It has excellent mechanical properties, corrosion resistance and decorative properties, and is widely used in construction, manufacturing, transportation, electronics, energy and other fields. Metal sheets can be made of different metal materials, such as aluminum, steel, copper, zinc, etc. These different metal materials have different characteristics and application ranges, so they are widely used in different fields. The manufacturing process of metal sheets is generally divided into raw material preparation, sheet rolling, surface treatment and cutting processing. In the raw material preparation stage, the required metal materials are selected and strictly inspected to ensure product quality. After the rolling process, the metal materials are continuously pressed and stretched to form metal sheets of the required size.

[0003] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket.

The coil is placed in the depression of the base shell, and the top of the depression is covered with a cover plate. When in use, the coil is energized by a wire, and after energization, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base.
