Abstract：

According to the technical requirements and forming difficulties of support seat, the layout was designed with unilateral carrier feeding and pilots for distance fixing, and the process bending edge was designed at unilateral carrier to increase the stiffness of the strip, and the pilots were set up to confirm the feeding distance. Then the feeding detection device was installed in the feeding end to power off automatically when there was a feeding error so as to protect the dies and equipment and realize automatic production easily. Furthermore, the multi-position progressive die was designed with obverse structure, and the different material removal devices were installed to exclude the blanking scraps and workpieces from die without the artificial separation. At the same time, the wedge sliding block mechanism was designed to ensure to the punch of side-hole, guide needles were set in the blanking stations to ensure the stamping accuracy. Finally, the multiple bending and successive bending process were designed, and the additional shaping process was put up to reduce the springback and ensure the shape and dimension accuracy requirements of the support seat. The results of production show that the design of multi-position progressive die can meet the production requirements.
