摘要
关于学校这次的毕业设计，我设计了Z形弯曲件的冲孔落料,弯曲模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Z形弯曲件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Z形弯曲件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，Z形弯曲件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Z形弯曲件设计说明书的工艺计算，主要Z形弯曲件的设计。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Z形弯曲件图绘制提供了依据。

Abstract

School graduation on this design, I designed a Z-shaped bend pieces of punching blanking, bending modulus composite mold set through the entire subject of elaborate design graduate, I have learned to mold design and manufacture all knowledge is a comprehensive review, after our inquiry and our school library materials, and this time I graduated from design issues related books, according to the related die design process step by step to the letter were produced, the time I graduated from design The entire design process to clearly written on the instructions of this.
　 　 In this design, the first Z-shaped bend pieces of the same processes were analyzed to calculate the process to determine the types of presses, and then express the design of the major components.
　　  The Z-shaped bend pieces of graduate design design specification is the first part of my graduation project of this first set of molds, Z-bend analysis blank piece composite blanking die punching process, the calculation process, The main components of the design. The Z-shaped bent piece design specification process calculation, the main piece of design Z-bend. This will provide an important basis for the selection of stamping equipment. Also based views of AutoCAD assembly drawing die design, as well as major Z-shaped bend pieces AutoCAD drawing provided.

　　Keywords: stamping die, Z-shaped bend pieces
