摘要：

针对一种微型电机外壳，分析了其结构特征和冲压工艺性，设计了包括拉深、冲孔、翻边、扩孔、切边、落料等17个工位的级进冲压工艺方案，采用了中间载体的排样形式和可变形的搭边方式，设计了由7个模块组成的倒装、镶拼式级进模结构。试冲结果表明：所采用的可变形搭边方式的材料利用率为83.4%，不仅提高了材料利用率、降低了生产成本，而且提高了材料流动性，在保证精度的基础上，更有利于制件的拉深变形；所采用的镶拼式模具结构具有较好的互换性，便于修配；采用吊楔结构完成冲孔和分离工序，模具整体结构紧凑。设计的搭边方式、排样方案和级进模结构合理、可行，能够满足实际生产的需要。

For a micro motor housing, its structure characteristics and stamping technology were analyzed, and a progressive stamping process scheme was designed with seventeen steps including deep drawing, punching, flanging, reaming, trimming, blanking, etc. Then, the layout method with intermediate carrier and the deformable lap edge form were adopted, and the progressive die structure composed of seven modules which were ejection port and insert type was designed. The test results show that the material utilization rate of deformable lap edge method is 83.4%, which not only improves the material utilization rate, reduces the production cost, but also improves the metal fluidity, and it is more conducive to deep drawing deformation of part on the basis of ensuring precision. Furthermore, the insert die structure has good interchangeability and is easy to repair, and the hanging wedge structure is adopted to complete the punching and blanking processes so that the die has a compact structure. In addition, the designs of deformable lap edge, layout scheme and progressive die structure are reasonable and feasible to meet the requirements of actual production.
