摘要

  关于学校这次的毕业设计，我设计了垫片的冲孔落料复合模一套经过毕业设计的整个课题精心制作，对我所学的模具设计与制造所有知识得到了一个全面的复习，经过查询我们的教材还有我们学校图书馆里的和我这次毕业设计课题有关的书本，根据模具设计的相关流程进行一步一步的不折不扣制作，把我这次毕业设计的整个设计过程给很清楚的写在这份说明书上了。

  在这次设计垫片同样先进行了工艺的分析，工艺的计算，确定压力机型号，再将各主要零部件的设计表达出来。

  这次毕业设计垫片设计说明书的第一个部分是对我这次毕业设计课题的第一套模具，垫片坯料的冲孔落料复合模的工艺的分析，工艺的计算，主要零部件的设计。这次垫片设计说明书的工艺计算，主要垫片的设计。这都为选择冲压设备提供重要依据。也为本次模具设计的AutoCAD装配图，以及AutoCAD主要垫片图绘制提供了依据。

第一章 概述

1.1毕业设计的目的

1、在这次毕业设计中通过对毕业设计的课题制作，对我们在学校老师所教的专业知识和我们自己所自学的专业知识进行一个巩固。

2、在这次毕业设计中培养我们模具专业的学生在遇到问题时的分析能力和解决问题能力，还有能独立的完成对于模具设计的流程的熟练制作。

3、在这次毕业设计中对我们模具设计与制造专业的学生工作作风以及责任心还有安全意识得到较大跨度的一个提升。

1.2 毕业设计的要求

1、毕业设计的图纸图幅量：一共要最少3张零号的图幅工作量（其中最少要有1张零号装配图，剩下的不做要求）。

 2、图纸：最后答辩前上交的图纸必须用AutoCAD绘制，画图时要更具绘图标准去画，最后要交1份AutoCAD图纸和1份1：1打印出来的图纸。

 3、毕业设计说明书的字数要求：不少于20000字。

4、查看和毕业设计课题有关的各种资料，为顺利的完成毕业设计以及能顺利毕业做好充分的准备工作。

5、要求计算准确、结构设计合理、图面整洁，图样及标注符合国家标准。

20、要求编制的工艺规程符合生产实际。

7、设计计算说明书要求文字通顺，书写工整。
