摘要：

基于DEFORM3D和UG/CAD的模具设计方法，针对数码分段开关外壳在单工序模具生产过程中高成本、低生产效率的问题，提出了使用多工位级进模具代替单工序模具的设计方案。分析了数码分段开关外壳件的冲压工艺性能，并对产品的排样方案进行了设计，以及对关键部件进行了设计与计算，设计出了一副将冲孔、切断、落料和弯曲集于一体的多工位级进模具，并说明了模具的具体工作过程。此副模具采用弹性卸料装置进行卸料，提高了生产效率。基于Deform3D进行数值模拟仿真分析，结果表明：该模具的工艺方案、排样和模具结构设计合理。实践证明，该级进模的结构紧凑、合理，便于加工维护，能够保证零件的成形质量并满足生产效率的要求。

Based on the die design method of Deform-3D and UG/CAD, for the problems of high cost and low production efficiency in the single-process die production process of digital sectional switch shell, a design scheme of using multi-position progressive die instead of single-process die was proposed, and the stamping technological property of the digital sectional switch shell was analyzed. Then, the layout plan of product was designed, and the key parts were designed and calculated. Furthermore, a multi-position progressive die including punching, cutting, blanking and bending was designed, and the specific working process of die was explained. In addition, the elastic unloading device was used to discharge, and the production efficiency was improved. The numerical simulation analysis based on Deform-3D shows that the process plan, layout and die structure design of this die are reasonable. The experiment shows that the progressive die has a compact and reasonable structure, which is easy to manufacture and maintain, and it can meet the requirements of forming quality and production efficiency for part.
