前 言
随着科学技术的发展需要，模具已成为现代化不可缺少的工艺装备，模具设计是机械专业一个最重要的教学环节,是一门实践性很强的学科，是我们对所学知识的综合运用，通过对专业知识的综合运用，使学生对模具从设计到制造的过程有个基本上的了解，为以后的工作及进一步学习深造打下了坚实的基础。
毕业设计的主要目的有两个：一是让学生掌握查阅查资料手册的能力，能够熟练的运用CAD进行模具设计。二是掌握模具设计方法和步骤,了解模具的加工工艺过程。
本书是落料冲孔拉深模设计说明书，结合模具的设计和制作，广泛听取各位人士的意见，经过多次修改和验证编制而成。为了达到设计的规范化,标准化和合理性，本人通过查阅多方面的资料文献，力求内容简单扼要，文字顺通，层次分明，论述充分。其中附有必要的插图和数据说明。 本书在编写过程中得到了老师的精心指导和同学们的大力帮助,在此表示衷心的感谢。由于本人是应届毕业生,理论水平有限，实践经验不足，书中难免有不当和错误的地方，敬请各位老师与广大读者批评指正。
