減速電機(jī)1315轉(zhuǎn)子片沖孔復(fù)合模具設(shè)計(jì)
摘要
本次針對(duì)轉(zhuǎn)子片，系統(tǒng)地進(jìn)行了一副落料、沖孔的復(fù)合模設(shè)計(jì)。在模具設(shè)計(jì)過程中，綜合運(yùn)用已學(xué)知識(shí)和自主創(chuàng)新來進(jìn)行設(shè)計(jì)和計(jì)算。本設(shè)計(jì)完整地進(jìn)行了制件的工藝性分析和模具設(shè)計(jì)的各項(xiàng)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(duì)沖壓件進(jìn)行了系統(tǒng)的沖壓工藝性分析；在模具設(shè)計(jì)方面，主要進(jìn)行了沖壓零件總體工藝方案的確定和排樣設(shè)計(jì)、工藝計(jì)算、工作部分參數(shù)計(jì)算、工作力的計(jì)算、模具總體結(jié)構(gòu)設(shè)計(jì)和主要零部件設(shè)計(jì)及主要零部件的加工工藝。
該落料沖孔復(fù)合模為倒裝式復(fù)合模，并采用了少?gòu)U料排樣中的直排形式，節(jié)省材料的浪費(fèi)，結(jié)構(gòu)簡(jiǎn)單?？梢灾苯永脡毫C(jī)的打桿裝置進(jìn)行推件，操作簡(jiǎn)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.
KEY WORDS: Compound dies; Press mold; Blanking; Punching; Mold design
