1、哈爾濱理工大學(xué)學(xué)士學(xué)位論文沖孔落料連續(xù)模設(shè)計(jì)及三維CAD實(shí)體動(dòng)畫仿真摘要連續(xù)模，又稱為多工位連續(xù)模、級(jí)進(jìn)模、跳步模，它是在一副模具內(nèi)，按所加工的工件分為若干等距離的工位，在每個(gè)工位上設(shè)置一個(gè)或幾個(gè)基本沖壓工序，來(lái)完成沖壓工件某部分的加工。被加工材料，事先加工成一定寬度的條料，采用某種送進(jìn)方法，每次送進(jìn)一個(gè)步距。經(jīng)逐個(gè)工位沖制后，便得到一個(gè)完整的沖壓工件。在一副級(jí)進(jìn)模中，可以連續(xù)完成沖裁、彎曲、拉深、成形等工序。一般來(lái)說(shuō)，無(wú)論沖壓零件形狀怎樣復(fù)雜，沖壓工序怎樣多，均可用一副級(jí)進(jìn)模沖制完成。本設(shè)計(jì)為沖孔、落料兩工位級(jí)進(jìn)沖裁模。首先，分析工件的尺寸及精度要求等個(gè)方面的
2、信息和要求，確定排樣圖和模具型式及總體結(jié)構(gòu)方案。然后根據(jù)工件分別計(jì)算和設(shè)計(jì)各2D零件草圖及修改、檢驗(yàn)、校核。接著，設(shè)計(jì)擋料裝置及定位裝置，由于本設(shè)計(jì)工件的精度要求不高且生產(chǎn)為中、大批量故采用自動(dòng)擋料裝置和定位銷裝置即可滿足要求。最后，檢驗(yàn)無(wú)誤后，用Pro/E軟件生成3D實(shí)體進(jìn)行動(dòng)畫仿真，以校驗(yàn)該設(shè)計(jì)的合理性及正確性。關(guān)鍵詞 連續(xù)模具；沖裁模；模具設(shè)計(jì)；仿真動(dòng)畫；Pro/E-II-哈爾濱理工大學(xué)學(xué)士學(xué)位論文PunchingcutMulti-positionprogressivemoldDesignAnd3D-CADAnimationSimulationAbstra
