XX 学院 毕业设计论文摘要摘要随着中国工业不断地发展，模具行业也显得越来越重要。本次毕业设计的任务是盖冒垫片冲压工艺分析和模具的具体结构设计。通过查阅了相关文献资料，对接触片零件进行工艺性分析，选择并确定符合于给定条件的最优工艺方案，及进行了工艺与设计的有关计算，如：选择基本工序，确定其顺序、工序数目及工序组合形式。介绍了主要零部件的设计理念，详细剖析了设计过程中一些思路，以及某些非标准零件的使用特点。阐述了复合模的设计要点, 使产品质量达到设计要求。然后以此为基础，设计出冲压模具主要零件的结构。并在设计中，介绍了零件的排样图、定位设计、冲裁力的计算和压力中心的计算。 关键词：盖冒垫片 模具设计 复合模 冲压工艺With the continuous development of Chinese industry, the mold industry has become increasingly important. The graduation projects mission is to take cover gasket stamping process analysis and design of the specific structure of the mold. By consulting the relevant literature, parts of the contact plate process analysis, selection and determine the conditions found at the given optimum solution, and carried out the calculation and design process, such as: choice of basic processes, determine their order, the number of processes and process combinations. Introduced the main components of the design concept, detailed analysis of the design process, some ideas, and some non-standard parts to use features. Describes the design features of the composite model, so the product quality to meet the design requirements. Then this basis, design the structure of the major parts stamping die. And in the design, the layout of parts described map, locate the design, calculation and blanking force center of pressure calculations.Keywords: Take cover gasket Mold Design Compound Die Stamping processXX 学院 毕业设计论文XX 学院 毕业设计论文3目录目录1 绪论.51绪论.11.1 冲压的概念、特点及应用.11.2 冲压的基本工序及模具.21.3 冲压技术的现状及发展方向.32工件工艺性分析.102.1 拉深工艺及拉深模有设计.102.2 有凸缘圆筒形件的拉深方法及工艺计算.112.3 宽凸缘圆筒形件的工艺计算要点.122.4 拉深凸模和凹模的间隙.132.5 拉深凸模，凹模的尺寸及公差.132.6 凹模圆角半径.152.7 凸模圆角半径.153冲裁工艺及冲裁模具的设计.173.1 凸模与凹模刃口尺寸的计算.173.2 凸、凹模刃口尺寸的计算方法.173.2.1 落料.183.2.2 冲孔.193.2.3 凹模洞的类形.193.2.4 凹模的外形尺寸.194模具的其它零件.224.1 模架.224.2 模柄.234.3 卸料板.244.4
