1、畢業(yè)設(shè)計(jì)(論文)題目后蓋沖壓模設(shè)計(jì)系別機(jī)械工程系專業(yè)班級(jí)機(jī)械工程及自動(dòng)化專業(yè)09K5班學(xué)生姓名指導(dǎo)教師二○一三年六月華北電力大學(xué)科技學(xué)院本科畢業(yè)設(shè)計(jì)(論文)后蓋沖壓模設(shè)計(jì)摘要沖壓加工技術(shù)始于18世紀(jì)末至19世紀(jì)中期,因?yàn)楫a(chǎn)業(yè)革命促成了動(dòng)力制造技術(shù)的發(fā)展,以機(jī)械化方式來加工金屬板就逐漸成為主流。隨著技術(shù)的不斷進(jìn)步,以及大量生產(chǎn)的需要,沖壓加工技術(shù)不斷的再改進(jìn),其發(fā)展進(jìn)步遠(yuǎn)比往昔更為迅速驚人。本文的主要內(nèi)容是構(gòu)建一個(gè)后蓋沖壓模具的工藝過程。通過對(duì)沖壓模具技術(shù)的了解、應(yīng)用,對(duì)沖壓件結(jié)構(gòu)形狀、批量大小和精度要求、進(jìn)行必要的工藝分析
2、及計(jì)算。主要包括對(duì)沖壓件的工藝分析,確定沖壓件生產(chǎn)的工藝方案,確定模具類型及結(jié)構(gòu)形式,選擇沖壓設(shè)備,繪制模具裝配圖和零件圖等。通過查文獻(xiàn)資料學(xué)會(huì)合理地選擇模具結(jié)構(gòu),正確地確定模具工作零件的結(jié)構(gòu)形狀、尺寸及其技術(shù)要求,使設(shè)計(jì)的模具制造工藝性良好,價(jià)格便宜,充分利用沖壓成型的特點(diǎn),設(shè)計(jì)制造出能優(yōu)質(zhì)、安全、高效生產(chǎn)地,使用壽命長(zhǎng)地模具,盡量減少后續(xù)加工。關(guān)鍵詞:沖壓技術(shù);沖壓模具;工藝分析;高效生產(chǎn)II華北電力大學(xué)科技學(xué)院本科畢業(yè)設(shè)計(jì)(論文)DESIGNOFSTAMPINGDIEFORCOVERAbstractStampingt
