Abstract：

The shape and structure of auto filter rear bracket contain stamping process features, such as punching, flanging, coining, bending and cutting. The analysis of part structure, batch production and stamping process shows that the progressive die can meet part production requirement. In order to ensure part precision and stamping process continuity, the process cut was designed with the same angle as the cutting station, a located slot was designed in the corresponding position of die, and the layout scheme of piercing, punching, bending and shaping was determined. The rail with guide nail to positioning method was used, and the internal and external guide mechanism and the elastic stripper device for stripper and holder were designed to ensure the product accuracy. Finally, the die was made and the stamping test was carried out. The results show that the structure of ten-station progressive die is reasonable, which meets requirements of both dimension and precision.
