Description
Technical Field
[0001] The utility model relates to the technical field of stamping dies, in particular to a two-sided chamfering structure of a washer progressive die. Background Art
[0002] Many stamping parts require through holes for stamping threads. When stamping such through holes, an internal chamfer needs to be set at the end. The function of this chamfer is to facilitate the subsequent tapping process. Originally, the step of setting the chamfer on the through hole was carried out after the through hole was stamped. Then, the stamping part was taken out and placed on a special lathe for subsequent processing.
[0003] Currently, during the processing of washer progressive dies in the market, it is often necessary to chamfer the coiled tape to improve the aesthetics and assembly performance of the product. However, traditional washer progressive dies have the following defects in two-sided chamfering processing:
[0004] 1. During the processing, the worker holds the coiled tape and places it on the lower die, and uses it in cooperation with the upper die to achieve chamfering of the coiled tape. Due to the lack of a limiting function, the coiled tape shifts during feeding, which will affect the chamfering effect of the coiled tape.
[0005] 2. After the chamfering of the coiled tape is completed, the excess stamping parts will fall below the device, which not only increases the labor intensity of the worker but also reduces the overall production efficiency. Summary of the Utility Model
