油泵壳体的冲压模具设计.rar

摘要
本次设计的题目是油泵壳体的模具设计。通过对制件的工艺分析,确定了模具的工艺方案。共分为两次拉深和一次冲孔翻边。本说明书主要阐述了油泵壳体的第一次拉深和冲孔翻边模具设计的基本过程及主要计算数据。
全篇共分为三章。第一章是设计油泵壳体模具的工艺方案的确定,主要根据所给制件特点加以分析,设计出合理的模具,这里共设计出两套模具。第二章是落料拉深复合模的设计,其中包括一些典型结构的选择和一些非标准零件的设计。第三章是冲孔翻边复合模的设计,包括各种模具零件的选择和一些零件尺寸的计算。第一套模具是典型的结构,第二套模具则根据制件工艺要求进行了部分创新。
鉴于本人的水平所限,在设计中肯定有不足之处存在,也会有很多错误出现,恳请评阅老师和各位读者包涵并且批评指正。

Abstract
The topic designed this time is the mold design of the shell of an oil pump. Through analysing to the craft which makes one , have confirmed the craft scheme of the mould. Divide it in order to draw and wash hole turn-ups with once deeply twice altogether. Manual this explain oil pump shell draw dark washing hole basic course , turn-ups of mold design and mainly calculating the datum for the first time mainly.
The whole one is divided into three chapters altogether. Chapter one the sureness of craft scheme of designing shell mould of the oil pump, the main foundation gives and makes a characteristic to analyse , design the rational mould, design two sets of moulds altogether here. Chapter two the blanking draws the design of the plex mould , including some choices of typical structure and the designs of some non-standard parts. Wash hole turn-plex design of mould , include various kinds of mould choice and some part calculation of size of part. The first set of moulds is the typical structure, the second set of moulds has innovated partly according to making a technological requirement.
Seeing that my level restricts, must there are weak points to exist in the design, a lot of mistakes will appear too , will earnestly ask to read and appraise the teacher and every reader and forgive and make ment.

第一章工艺方案的确定
(一)油泵壳体的工艺分析
油泵壳体属于圆筒阶梯拉深件,工件材料为08 AL,,结构简单。特点是工件要求精度不高,经过两次拉深,冲孔翻边即可。制件结构对
