摘　　要：冷挤压工艺复杂,影响因素多,造成冷挤压工艺设计难度大。现有冷挤压工艺CAPP系统缺乏对工艺和模具的验证、优化手段。基于派生式设计方法,通过人机交互式手段,对冷挤压零件进行分类编码;通过编码检索得到冷挤压工艺和模具的初始设计;用有限元模拟和批处理技术,对冷挤压工艺设计进行数值模拟;基于模拟结果,判断工艺可行性,提出优化方案。将开发的冷挤压工艺CAPP系统应用于工厂实例,证明本系统大大减少了冷挤压工艺和模具设计开发时间,提高了设计效率和质量。Cold extrusion processing is complexity, and affected by many factors, which cause design difficulty. Many existed CAPP systems for cold extrusion lack the verification and optimization method of process and die design. The parts codes could be classified by variant method and user interface. The initial design of cold extrusion process and die was obtained by code retrieval. The numerical simulation of cold extrusion process was made by finite element method and batch method, which provided the feasibility of process evaluation and optimization. The developed CAPP system is applied to factory examples, which shows many advantages, such as, reducing the design time, improving the design efficiency and quality.
