摘要：

根据接线固定支架的结构特点、技术要求和材料的性能，对两种不同的接线固定支架成形排样进行了分析、比较，对生产中可能出现的问题提出了解决办法，最后提出了合理的排样，其有利于材料成形控制；在此基础上，设计了接线固定支架多工位级进模，采用了燕尾槽组合成形凸模结构，解决了接线固定支架多工位级进模的自动卸料难点；针对接线固定支架多工位级进模的结构特点，提出了此类级进模设计及制造时应注意的事项。通过企业生产证明, 此接线固定支架多工位级进模在生产时送料顺畅、自动卸料方便、模具寿命长，产品完全达到了用户要求。

According to the structural characteristics, technical requirements and material performance of wiring fixing bracket, the layouts of two different wiring fixing brackets were analyzed and compared, and the solutions to problems that might arise in the production were proposed. Finally a reasonable layout was put forward, which was conducive to control the material forming. On this basis, a multi-position progressive die for wiring fixing bracket was designed, and the forming punch structure of dovetail groove combination was adopted to solve the difficulty of automatic unloading in the multi-position progressive die for wire fixing bracket. Furthermore, according to the structure characteristics of the multi-position progressive die for wire fixing bracket, the attention points in the design and manufacture of such progressive die were put forward. The production of enterprise shows that the multi-position progressive die of wire fixing bracket has smooth feeding, convenient automatic unloading and long die life, and the products completely meet the requirements of users.
