As the foundation of the automobile industry, auto parts are necessary factors to support the sustainable and healthy development of the automobile industry. In the process of auto parts processing, the sheet metal needs to be bent to form a bent product of a specific shape. Stamping machines are often used to stamp and bend plate parts.

[0003] There are many existing technologies for bending automotive parts, such as:
