摘 要
介紹了軸承蓋冷沖壓成形過(guò)程，經(jīng)過(guò)對(duì)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?yàn)椋郝淞稀⒗睢_孔，然后根據(jù)對(duì)工序的初步計(jì)算，確定工序數(shù)目，如沖壓次數(shù)，拉深次數(shù)，對(duì)工序順序的安排，一般根據(jù)各工序的變形特點(diǎn)，質(zhì)量要求來(lái)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?yàn)樯a(chǎn)批量大，所以將各個(gè)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(guò)充分利用現(xiàn)代模具制造技術(shù)對(duì)傳統(tǒng)機(jī)械零件進(jìn)行結(jié)構(gòu)改進(jìn)、優(yōu)化設(shè)計(jì)、優(yōu)化工藝方法能大幅度提高生產(chǎn)效率，這種方法對(duì)類(lèi)似產(chǎn)品具有一定的借鑒作用。

ABSTRACT
Introduced to carry the bearing cover cold hurtle to press to take shape the process, pass by to the batch quantity production, spare parts quantity, the spare parts structure and usage request of carry the bearing cover of analysis, study, according to not lower to use the function as premise, is certain in order to hurtle to press the piece, it uses to hurtle to press the method to complete the spare parts to process, hurtling to press basic work preface is: Fall to anticipate, pull deep, hurtle the bore, then according to the initial calculation of the work preface, make sure the work ordinal number eyes, if hurtle to press the number of times, pulling the deep number of times, to the in proper order arrangement of the work preface, general transform the characteristics according to each work preface, the quantity request to certain, because of in order to take the bore to fall to anticipate, pull the deep piece, this work piece so fall to anticipate first, then pull deeply, blunt bore of end, according to produce the batch quantity and condition( hurtle to press to process the condition and molding tools to make the condition)s to make sure the work that the preface combine, because of produce the batch quantity big, so combine each work preface together, counteract compound the mold hurtles to press, raising the rate of production of the product thus. Pass to make use of the modern molding tool manufacturing technique to carry on the structure improvement to the traditional machine spare parts well, excellent turn the design, the excellent chemical engineering skill method ability the significant exaltation produces the efficiency, this kind of method to similar the product has to certainly draw lessons from the function.
Key words: bearing cover; stamping; process; Production batch; Production efficiency
