畢業(yè)設(shè)計(jì)論文中型換熱片用沖壓模具設(shè)計(jì)

1、摘 要I摘 要本論文根據(jù)產(chǎn)品圖樣，分析沖裁件的形狀、特點(diǎn)、尺寸大小精度要求、表面質(zhì)量及所用材料等沖壓工世性，在此基礎(chǔ)上，分別設(shè)計(jì)復(fù)合模 及壓紋等單工序模具，實(shí)現(xiàn)流水線作業(yè)。流水線作業(yè)是本次設(shè)計(jì)的亮點(diǎn)所在。凸模采用成型加工或線切割，沖裁部分進(jìn)行熱處理，由螺釘固定，剛性推件，彈性卸料裝置橡膠的彈性把料板由下而上推出，隨上模的動(dòng)作而動(dòng)作，運(yùn)動(dòng)平穩(wěn)可靠且不易損壞模具，采用中間導(dǎo)柱圓形有利用安裝，且因安裝不當(dāng)而造成模具損壞，根據(jù)沖壓力選擇開式
