弯曲翻边复合模具设计

The Composite Die Design of Bending Flanging

根据零件的结构特点及技术要求，围绕如何降低生产成本、提高工作效率、简化模具结构，通过多种工艺方案比较，制订了一套由落料、冲孔复合（两件合坯）-弯曲、翻边复合-冲侧孔-切断等工序组成的冲压工艺方案。对其所有工序进行了工艺计算，详细设计了难度较大的一副弯曲、翻边复合模具结构。说明了采用此工艺方案和模具结构，显著提高锁片零件的生产效率和产品质量。

In this paper, a set of punching program made up of the blanking, punching composite （two $ billet）, bending, flanging composite--blunt side hole--cutting process of stamping process program is designed according to the feature of the parts andtechnieal nequirement, with the center point to lower the productive cost, and improve the efficiency. Through the craft calculation, a set of difficult bending, side --turning--over model construction is designed detailed. By using this set of mold structure and craft, the product quality and productive efficiency are greatly improved.
