1、 1 毕毕 业业 设设 计计 说说 明明 书书 题 目 端盖落料拉深冲孔复合模设计 系 别 机械电子工程系 专 业 机械设计与制造 班 级 姓 名 学 号 指导教师 日 期 2 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。本文针对端盖的冲裁工艺 性和拉深工艺性，分析比较了成形过程的三种不同冲压工艺（单工序、复合工序和连续工 序） ，确定用一幅复合模完成落料、拉深和冲孔的工序过程。介绍了端盖冷冲压成形过程， 经过对端盖的批量生产、零件质量、零件结构以及使用要求的分析、研究，按照不降低使 用性能为前提， 将其确定为冲压件， 用冲压方法完成零件的加工， 且简要分析了坯料形状、 尺寸，排

2、样、裁板方案，拉深次数，冲压工序性质、数目和顺序的确定。进行了工艺力、 压力中心、模具工作部分尺寸及公差的计算，并设计出模具。还具体分析了模具的主要零 部件（如凸凹模、卸料装置、拉深凸模、垫板、凸模固定板等）的设计与制造，冲压设备 的选用，凸凹模间隙调整和编制一个重要零件的加工工艺过程。列出了模具所需零件的详 细清单，并给出了合理的装配图。通过充分利用现代模具制造技术对传统机械零件进行结 构改进、优化设计、优化工艺方法能大幅度提高生产效率，这种方法对类似产品具有一定 的借鉴作用。 关键词关键词：端盖；模具设计；复合模；拉深冲孔 3 ABSTRACT With Chinas industries
