減速電機1315轉(zhuǎn)子片沖孔復合模具設(shè)計
摘要
本次針對轉(zhuǎn)子片，系統(tǒng)地進行了一副落料、沖孔的復合模設(shè)計。在模具設(shè)計過程中，綜合運用已學知識和自主創(chuàng)新來進行設(shè)計和計算。本設(shè)計完整地進行了制件的工藝性分析和模具設(shè)計的各項內(nèi)容，從形狀工藝性分析、尺寸和精度工藝性分析、結(jié)構(gòu)工藝性分析等方面對沖壓件進行了系統(tǒng)的沖壓工藝性分析；在模具設(shè)計方面，主要進行了沖壓零件總體工藝方案的確定和排樣設(shè)計、工藝計算、工作部分參數(shù)計算、工作力的計算、模具總體結(jié)構(gòu)設(shè)計和主要零部件設(shè)計及主要零部件的加工工藝。
該落料沖孔復合模為倒裝式復合模，并采用了少廢料排樣中的直排形式，節(jié)省材料的浪費，結(jié)構(gòu)簡單。可以直接利用壓力機的打桿裝置進行推件，操作簡單。采用彈性橡膠作為壓料裝置，壓邊力較為均勻。

Abstract
For the cover of this, the system carried out a blanking, punching of the compound die design. The design completely include the process of analysis and all the content of mold design. From the shape of analysis, size and accuracy of analysis, structure of analysis to analyze the system of stamping process; In the part of mold design, the main components include determing the overall stamping process, process and layout design plans, Technology Calculation, the calculation of some parameters, The calculation of work force, overall structural design and the main components design.
The blanking die for the fall in compound punching loading composite mold, and uses less waste in the vertical layout format, saving materials, waste, simple structure. You can directly use the press to push device of playing the rod pieces, easy to operate. Adopt a flexible rubber as a pressing device, the pressure side where more evenly.
