摘　　要：通过对DXF文件结构及内容、二维冲裁件图形几何信息及拓扑关系的分析,研究了从DXF文件中获取图形数据的方法和基于UG平台的冲裁模CAD系统的二维图形信息在计算机内的存储结构及其信息识别方法,并根据其数据结构特征,构造出了一种二维图形的数据模型,运用C语言直接对文件进行数据提取,然后按照一定的算法识别提取出的数据,构建起冲裁件的几何模型,为冲裁模工艺可行性分析、工艺设计和优化排样提供了必要的信息。Through the analysis of the structure, content of DXF files and the analysis of the geometric information and topological relationship of 2D blanking part, an investigation on the method of the storage organization of the 2D blanking drawings, the extraction and reorganization of it＇ s information in the computer is conducted based on UG platform, and meanwhile, a data model is constructed to save the 2D drawing information, the use of C language directly extract data of the document, and then in accordance with a certain algorithms identify extract data, and build a geometric model of blanking part, which provides the necessary information for the later blanking technology feasibility analysis, the blanking technology design and the optimal blank layout of blanking dies.
