8、定該工件包括落料沖孔兩個(gè)基本工序，可有以下三種工藝方案：-13-方案一：先落料，后沖孔。采用單工序模生產(chǎn)。方案二：落料—沖孔復(fù)合沖壓。采用復(fù)合模生產(chǎn)。方案三：沖孔—落料級(jí)進(jìn)沖壓。采用級(jí)進(jìn)模生產(chǎn)。方案一模具結(jié)構(gòu)簡(jiǎn)單，但需要兩道工序兩套模具，成本高而生產(chǎn)效率低，難以滿足大批量生產(chǎn)要求。方案二只需一套模具，工作精度及生產(chǎn)效率都比較高，但制造難度大，并且沖壓成品件留在模具上，清理模具上的物料影響沖壓速度，操作不方便。方案三也只需要一副模具，生產(chǎn)效率高，操作方便，設(shè)計(jì)簡(jiǎn)單，由于
