Technical Field

[0001] The utility model relates to the technical field of stamping dies, and more specifically, to a sheet metal stamping die for automobile stamping parts. Background Art

[0002] Automotive sheet metal stampings are sheet metal parts used in the automotive industry, manufactured through a stamping process. They are usually made of metal sheets through processes such as punching, bending, stretching or pressing to meet specific needs in automotive manufacturing.

[0003] Automotive sheet metal parts are important components in automobile manufacturing. The production of automotive sheet metal parts mostly requires the use of die stamping to obtain the required sheet shape. The relevant automotive sheet metal stamping dies directly affect the quality of the product. Although the production process of existing automotive sheet metal stamping dies is becoming more and more mature, in actual production and use, after the stamping die is completed on the sheet metal parts, the sheet metal parts are easily embedded in the inside of the lower die due to the strong pressure of the pneumatic cylinder, which makes it inconvenient to remove them. The operator needs to use tools to remove the sheet metal parts from the lower die. This method not only increases the workload of the operator, but also reduces the processing efficiency, so it needs to be improved. Utility Model Content
