基于现代设计方法和计算机信息技术 ,开发了基于功能 -结构映射、支持自上而下整体设计的客车件冲裁模CAD系统。介绍了系统的总体结构、模具设计功能树的建立思想和层次化部件装配模型的特点 ,阐述了模具结构设计过程中不同层次上设计信息的处理方法 ,并通过一功能元件的设计实例说明了基于该系统的冲模设计过程。
Based on the modern design method and the computer information technology, a CAD system for passenger car blanking die based on function-structure mapping and top-down overall design was developed. The general structure of the system, the idea of building the function tree of the mold design and the characteristics of the hierarchical assembly model are introduced. The design information processing methods at different levels of the mold structure design are expounded. The design example of a functional element shows that the design method based on The system of die design process.
