Description

Technical Field

[0001] The utility model relates to a stamping die, in particular to a multi-angle swing block forming structure. Background Art

[0002] Stamping die is a special process equipment that processes materials (metal or non-metal) into parts in cold stamping process. Figure 1 As shown, product 100 is a highly used automotive accessory requiring high dimensional stability. During the molding process, product 100 faces the following challenges: 1. The product's large shape, curved surfaces, and punched holes at the bends make positioning difficult and result in poor dimensional stability. 2. The complex shape of the product, including negative angles, interferes with the shape of the side edges 101 of product 100 after molding, resulting in the product clinging to the mold and making removal difficult. 3. The molding process lacks effective compression (the molding surface exhibits convex hulls and short straight segments), resulting in dimensional instability after molding and potentially damaging the dimensions of the preceding process.
