Description

Technical Field

[0001] The utility model relates to the field of stamping dies, in particular to a forming die for an automobile fender. Background Art

[0002] The fender has different molding methods according to different materials. According to market demand, our company has designed a fender made of metal. The fender of this material is generally processed and manufactured by sheet metal technology.

[0003] In the process of manufacturing fenders using sheet metal technology, the semi-finished fenders need to be punched out to form a contour, that is, the pre-pressed fenders are punched out by a stamping die to cut off excess material on the semi-finished fenders.

[0004] The fender is usually placed on the punch of the stamping die for punching. The punch is provided with a notch structure, which often cooperates with the punch in the die to punch the waste. Therefore, the notch structure is a vulnerable structure on the punch. However, in the traditional stamping die for punching fenders, the notch structure is opened on the convex plate. Once the notch is excessively worn, the entire convex plate needs to be repaired, which will affect the manufacturing period of the fender and even cause the fender to be unable to be delivered on time. More importantly, if the notch part cannot be repaired, the entire convex plate will be scrapped, resulting in waste of materials and increased costs. Summary of the invention
