摘要：

根据支承座的技术要求和成形难点，设计了单侧载体送料加导正销定距的排样方式，在单侧载体上设置工艺弯边增大料带的刚度，设置导正销确定送料进距；在送料末端设置了送料检测装置，出现送料错误时会自动断电，保护模具和设备，便于实现自动化生产；支承座多工位级进模采用顺装结构，设置了不同的除料装置，以保证各冲裁废料和工件从模具中的排除，免于人工分离；设计了斜楔滑块机构，保证侧孔的冲裁；在冲裁工位设置了导正针，保证模具的冲压精度；采用逐次弯曲或多次弯曲的弯曲成形工艺，并增设了整形工序，以减少弯曲过程中的回弹，保证了支承座的形状和尺寸精度要求。生产结果表明，支承座多工位级进模的设计能满足生产要求。

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.
