1、 编号： 毕业设计毕业设计说明说明书书 题 目：盒形件冲压工艺分析及复合模 设计 学 院： 机电工程学院 专 业： 机械设计制造及其自动化 学生姓名： 学 号： 指导教师单位： 机电工程学院 姓 名： 职 称： 讲 师 题目类型：理论研究 实验研究 工程设计 工程技术研究 软件开发 2014 年 5 月 24 日 摘 要 该套模具制造简单,但需要多套模具,效率低、流程路线太长,过程分离,更难保证零 件的精度和技术要求,并且过程自动化程度不高,生产成本也非常高,已经不能满足现代 机械加工的需求。所以为了解决这种问题,针对冲压工艺和矩形盒拉深过程,首先介绍了 盒形件冷冲压成形过程，通过对盒形件的批

2、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，等设计出三种不同的冲压工艺方案并且分 析和比较的形成过程包括单一过程,复杂的过程和持续的过程也就是我们常说的单工 序、复合工序和连续工序,最终确定用一套复合模完成落料、拉深、冲底面矩形孔，翻 边的工序过程。精加工冲压方法,力的计算,模具尺寸和公差,和设计模具。一份详细的 零件清单和所需的模具,并给出一个合理的装配图。给未来的设计提供了一个参考，借 鉴执笔的成效。 关键词：盒形件；拉伸；复合模；模具设计 Abstract The mold manufacturing is simple, but need more

3、sets of molds, low efficiency, process route is too long, the separation process, more difficult to guarantee precision parts and technology, and process automation degree is not high, the production cost is also very high, has been unable to meet the demand of modern machining. So in order to solve

4、 this problem, the stamping process and the deep drawing process of rectangular box, introduced the process of cold stamping parts box.So in order to solve this problem, in view of the stamping process and the rectangular box deep drawing process, cold stamping process, the box parts are introduced

5、through the quality of mass production of box parts, parts, parts structure as well as the use requirement analysis the box shaped parts of the mass production, quality components, parts structure and analysis, requirements of the study, in accordance with the use of performance is not reduced, will

6、 determine its stamping parts, three stamping process analysis and comparison of different process involves the formation of a single process, complex process and continuous process is what we often say that the single processes, complex processes and continuous processes, determined by a set of compound die blanking, drawing, punching bottom moment face process. Fine punching method, calculation of the forc
