Description

Bending riveting die structure in progressive die

Technical Field

The utility model relates to the technical field of progressive dies, in particular to a progressive die inner bending riveting die structure.

Background

The continuous die is a cold stamping die which adopts a strip-shaped stamping raw material in one stamping stroke of a press machine and simultaneously completes a plurality of stamping processes by using a plurality of different stations on a pair of dies, and the material strip moves once at fixed intervals every time the dies complete stamping until the product is completed. In the existing progressive die operation, each station can only finish one process, and as a result, the processing needs to be performed at different stations. Some work operations are performed even by a plurality of devices. If a certain part of the product is required to be bent, the bent part is required to be riveted. The bending operation is generally performed through one station, and after the bending operation is completed, the bending operation is transferred to the next station, and then riveting is performed, or the bending operation is performed on one device, and after the bending operation, the riveting operation is performed by changing the bending operation into another device. However, these two working methods have a large number of working steps, long working time and low productivity.
