1、吊耳加強(qiáng)板的沖壓工藝與沖模設(shè)計(jì)摘要:近年來,我國家電工業(yè)的高速發(fā)展對(duì)模具工業(yè),尤其是冷沖模具提出了越來越高的要求,2004年,冷沖模具在整個(gè)模具行業(yè)中所占比例已大大上升,據(jù)有關(guān)專家預(yù)測(cè),在未來幾年中,中國冷沖模具工業(yè)還將持續(xù)保持年均增長速度達(dá)到15%左右的較高速度的發(fā)展。沖壓成型是金屬成型的一種重要方法,它主要適用于材質(zhì)較軟的金屬成型,可以一次成型形狀復(fù)雜的精密制件。本課題就是將石化、化工、電力等行業(yè)的法蘭密封結(jié)構(gòu)中的墊片作為設(shè)計(jì)模型,將冷沖模具的相關(guān)知識(shí)作為依據(jù),闡述冷沖模具的設(shè)計(jì)過程。本設(shè)計(jì)對(duì)帶法蘭U型件進(jìn)
2、行的模具設(shè)計(jì),利用AutoCAD軟件對(duì)制件進(jìn)行設(shè)計(jì)繪圖。明確了設(shè)計(jì)思路,確定了沖壓成型工藝過程并對(duì)各個(gè)具體部分進(jìn)行了詳細(xì)的計(jì)算和校核。如此設(shè)計(jì)出的結(jié)構(gòu)可確保模具工作運(yùn)用可靠,保證了與其他部件的配合。并繪制了模具的裝配圖和零件圖。本課題通過對(duì)工件的沖壓模具設(shè)計(jì),鞏固和深化了所學(xué)知識(shí),取得了比較滿意的效果,達(dá)到了預(yù)期的設(shè)計(jì)意圖。關(guān)鍵詞:沖壓模具;沖壓成型;模具設(shè)計(jì)指導(dǎo)老師簽名:LugReinforcementstampingprocessanddiedesignStudentname:luoxianmingClas
