Abstract：

The shape of car rear bracket is complex with the characteristics of punching, embossing, flanging and bending. The analysis of stamping process shows that a progressive stamping process is suitable for large-scale production and can guarantee the dimensional accuracy of the part. A nesting design of eighteen-position with single-row, oblique configuration and middle carrier was designed according to the characteristic of the part and the analysis the configuration type, carrier style and manufacture order. Based on the nesting design, punch and die structure of the progressive die and auxiliary structural parts, such as the punch of oblique edge blanking and the device preventing scrap floating using spring plunger, the assembly of the progressive die was completed at last. The result of the actual production shows that the eighteen-position progressive die is of high quality, structural reliability, and good efficiency, which meets the requirement of large-scale production.
