1、軸承蓋落料、拉深、沖孔復(fù)合模28摘要介紹了軸承蓋冷沖壓成形過程，經(jīng)過對軸承蓋的批量生產(chǎn)、零件質(zhì)量、零件結(jié)構(gòu)以及使用要求的分析、研究，按照不降低使用性能為前提，將其確定為沖壓件，用沖壓方法完成零件的加工，沖壓基本工序為：落料、拉深、沖孔，然后根據(jù)對工序的初步計算，確定工序數(shù)目，如沖壓次數(shù)，拉深次數(shù)，對工序順序的安排，一般根據(jù)各工序的變形特點，質(zhì)量要求來確定，由于本工件為帶孔的落料、拉深件，因此先落料，再拉深，最后沖孔，根據(jù)生產(chǎn)批量和條件（沖壓加工條件和模具制造條件）確定工序組合，因為生產(chǎn)批量大，所以將各個工序組合在一起，并用復(fù)合模沖壓，這樣就提高了產(chǎn)品的生產(chǎn)率。通過充分利用現(xiàn)代模具制造技術(shù)對傳
