1、摘要本設(shè)計(jì)題目為銅片沖孔落料級(jí)進(jìn)模模設(shè)計(jì)，體現(xiàn)了沖孔落料類零件的設(shè)計(jì)要求、內(nèi)容及方向，有一定的設(shè)計(jì)意義。通過對(duì)該零件模具的設(shè)計(jì)，進(jìn)一步加強(qiáng)了設(shè)計(jì)者沖裁模設(shè)計(jì)的基礎(chǔ)知識(shí)，為設(shè)計(jì)更復(fù)雜的沖裁模具做好了鋪墊和吸取了更深刻的經(jīng)驗(yàn)。本設(shè)計(jì)運(yùn)用沖壓工藝及模具設(shè)計(jì)的基礎(chǔ)知識(shí)，首先分析了工件的工藝要求，為選取排樣的類型做好了準(zhǔn)備；然后估算了板料的選取，便于導(dǎo)尺的寬度及確定排樣的方法；最后分析了工件的特征，確定模具的設(shè)計(jì)參數(shù)、設(shè)計(jì)要點(diǎn)及自動(dòng)漏料裝置。本工件為薄板的沖孔落料見，且工件的料厚較薄，所以在選取壓力機(jī)是不宜過大
2、，材料上說銅料的屈服強(qiáng)度也沒有鋼料的大，工件的尺寸較小設(shè)計(jì)時(shí)必須考慮設(shè)計(jì)一個(gè)能在沖孔落料時(shí)的剪切力小于材料的屈服強(qiáng)度以免沖裁力過大沖出廢件。關(guān)鍵詞：沖裁模沖裁極限強(qiáng)度24AbstractBlankandPrerceGrogressiveDiesThisdesigntopichurtlesboretofalltoanticipateclasstoenteramoldmolddesignforthecopper,bodynowthebluntborefalltoanticipateatypeofspare
