摘要：本次毕业设计的内容是用模具生产固定托架，并且制定出相关的工艺路线，设计出生产所用模具。主要工序有落料、拉深、冲孔、切边。在设计模具之前应注重实际。所以在我查阅了许多资料与文献和对产品零件的外形尺寸的理解与分析下终于筛选出来冲压模具。冲压模具的设计不仅考虑了经济性、与设计的成本还有设计的复杂性与工艺的深浅性。更方便了对产品毛坯的展开尺寸计算。通过对模具的主要零件图的的尺寸大小，和详细的零件结构设计，最后总汇出总装配图，使其相得益彰。40976
毕业设计内容是：托架零件成型工艺及复合模设计。毕业设计不仅仅对我是一个考验更是对我的能力和在大学四年中所学知识的一个考核表。他不仅仅能磨练我的CAD，UG水平，更能锻炼我的查阅参考文献与资料的能力，与老师交流的能力等。这次毕设让我学到了很多。
最后，感谢一下付泽民老师的帮助与教导，因为他不厌其烦的教导，才能让我顺利的完成这次毕设，毫无遗憾的走上社会。谢谢老师，也谢谢学校。

Forming process and design of compound die for bracket parts
Abstract: the content of this graduation project is to use the mold to produce the fixed bracket, and to make the related craft route, and design the mould for the production. The main processes are blanking, drawing, punching, cutting edge. Prior to the design of the mold should pay attention to the actual. So I consulted a lot of information and literature and the analysis of the shape and size of the product part of the understanding and analysis finally screened out stamping die. The design of stamping die not only considers the economy, but also the cost of the design and the complexity of the design and the depth of the process. It is more convenient to calculate the size of the product. The size of the mold parts drawing, and detailed structure design of parts and final confluence a total assemble diagram, bring out the best in each other.
My graduation design content is: the bracket parts forming process and the compound mold design. Graduation design is not only a test of my ability and the ability of the University in four years to learn the knowledge of a test table. He can not only hone my UG, CAD level, but also to exercise my ability to consult the literature and information, the ability to communicate with the teacher, etc.. This time I learned a lot.
Finally, thanks to a Fu Zemin teacher to my help and teach, for his tireless teachings, can let me smooth completion of the complete set, no regrets go society. Thank you, teacher, thank you for your school.
Key words: blanking; drawing; cutting edge; punching; compound die; Technology
