冲裁力与压力中心计算机辅助设计 摘要：计算机辅助设计（CAD）技术起步于上世纪50年代后期，经过半个多世纪的发 展，冃前国内外已研发出许多通用的CAD软件。冲裁模的压力屮心计算是否准确对于 模具结构设计非常重要。随着计算机辅助设计技术（CAD）的进步，使用计算机自动 计算冲裁件冲裁力和压力屮心，已经口益成为冲压模具设计的必然趋势。在本文屮， 研究了基于VB环境下的压力屮心CAD系统的开发，对其方法、过程及手段，进行系 统的、全面的研究和阐述，对系统的正常运行提供了指导，不仅可以提高设计效率和 设计质量，并能进一步开发CAM系统，满足市场的需求，适应时代的发展。 本文完成的主要任务有： 1 ?阐述了 CAD技术的基本理论，包括其概念、原则等。 介绍了压力屮心CAD系统的设计理念、原理、过程和一些关键技术，并进行分 析； 利用AutoCAD辅助法，完成压力屮心CAD系统设计。 关键词：CAD,压力屮心，设计，系统 Blanking Force and Center Of Pressure Computer Aided Design Abstract： Computer aided design (CAD) technology started in the late 1950 s, after more than half a century of development, many general CAD software have been developed at home and abroad, whether The precision of center of pressure calculation of blanking die is very important to the design of die structure. As CAD technology progresses, using the computer to automatically calculate blanking part blanking force and center of pressure has increasingly become an inevitable trend of stamping die design. This paper was focused on the research of the center of pressure of CAD system based on VB environment, with the aim to provide guidance for the normal operation of the system. A systemic overview on the method and process and method was carried out.lt is not only improving the design efficiency and quality, but also further development of CAM system, which meet the demand of the market and consistent with the development of modern technology. Main tasks of this paper are: This paper expounds the basic theory of CAD technology, including its concept, principle, etc; This paper introduces the pressure center of CAD system design idea, principle, process and some key technologies, and analyzed; The design of the pressure center CAD system is completed by AutoCAD assistant method.
