Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a combined automotive parts stamping die. Background Technology

[0002] Stamping dies are key process equipment used for forming and processing metal sheets. They apply external force to the sheet metal through a press and a die, causing it to undergo plastic deformation or separation, thereby obtaining parts of the required shape and size. Dies typically consist of an upper die, a lower die, a guiding device, and a positioning mechanism. They are characterized by high efficiency, high precision, and mass production capabilities, and are widely used in industries such as automobiles, electronics, and home appliances. They can produce a variety of products, from simple stamped parts to complex cover parts. Their design and manufacturing level directly affects the quality of stamped parts and production costs.

[0003] In the existing technology, the support frame of the battery pack usually adopts a square tube metal structure, which is mainly used to support the weight of the battery and prevent external impacts. However, metal sheets usually cannot be directly made into square tubes through stamping process. In its manufacturing process, the sheet is often first sent into a mold to be stamped into a U shape, and then sealed into a round tube through welding process. Then, the workers transfer the round tube material to another mold to be stamped into a square tube. The whole process is relatively complicated and increases the workload of the workers.

[0004] Therefore, this utility model provides a combined automotive parts stamping die to solve the above problems. Utility Model Content
