1、XX大學(xué)畢業(yè)設(shè)計(jì)題目機(jī)芯自停連桿的沖壓模具設(shè)計(jì)系別專(zhuān)業(yè)班級(jí)姓名學(xué)號(hào)指導(dǎo)教師日期33設(shè)計(jì)任務(wù)書(shū)設(shè)計(jì)題目:機(jī)芯自停連桿的沖壓模具設(shè)計(jì)設(shè)計(jì)要求:1.自停連桿工藝性分析及沖裁方案的確定;2.有關(guān)計(jì)算及模具設(shè)計(jì);3.模具制造工藝編制與裝配。設(shè)計(jì)進(jìn)度:第一周:收集資料第二周:主要設(shè)計(jì)計(jì)算第三周:結(jié)構(gòu)設(shè)計(jì)第四周:模具的整體設(shè)計(jì)第五周:撰寫(xiě)論文第六周:校核、修改、提交論文第七周:論文答辯指導(dǎo)教師(簽名):33摘要我本次設(shè)計(jì)的零件為錄音機(jī)機(jī)芯自停連桿。此工件采用的材料鋼10及厚度0.8mm保證了足夠的強(qiáng)度和剛度,該零件外形復(fù)雜,工序煩瑣,故設(shè)計(jì)成級(jí)進(jìn)模進(jìn)行沖裁,在沖裁中對(duì)
2、小凸模進(jìn)行保護(hù)。合理排樣、減小廢料。材料為優(yōu)質(zhì)碳素鋼,采用沖壓加工經(jīng)濟(jì)性良好。首先對(duì)零件進(jìn)行了工藝性分析,然后選級(jí)進(jìn)模作為該副模具的工藝生產(chǎn)方案,經(jīng)過(guò)計(jì)算分析完成該模具的主要設(shè)計(jì)計(jì)算,凸、凹模工作部分的設(shè)計(jì)計(jì)算,還有主要零部件的結(jié)構(gòu)設(shè)計(jì),。完成一系列的計(jì)算后,畫(huà)出總裝圖、凸凹模配合圖等設(shè)計(jì)模具必備的圖紙。完成模具設(shè)計(jì)的大部分程序。進(jìn)行沖壓設(shè)計(jì)就是根據(jù)已有的生產(chǎn)條件,綜合考慮影響生產(chǎn)過(guò)程順利進(jìn)行的各方面因素,合理安排零件的生產(chǎn)工序,最優(yōu)地選用,確定各工藝參數(shù)的大小和變化范圍,設(shè)計(jì)模具,選用設(shè)備等,以使零件的整個(gè)生產(chǎn)過(guò)程達(dá)到優(yōu)質(zhì),高產(chǎn),低耗,安全的目的。關(guān)鍵
