内容简介：

摘 要介绍了轴承盖冷冲压成形过程，经过对轴承盖的批量生产、零件质量、零件结构以及使用要求的分析、研究，按照不降低使用性能为前提，将其确定为冲压件，用冲压方法完成零件的加工，冲压基本工序为：落料、拉深、冲孔，然后根据对工序的初步计算，确定工序数目，如冲压次数，拉深次数，对工序顺序的安排，一般根据各工序的变形特点，质量要求来确定，由于本工件为带孔的落料、拉深件，因此先落料，再拉深，最后冲孔，根据生产批量和条件（冲压加工条件和模具制造条件）确定工序组合，因为生产批量大，所以将各个工序组合在一起，并用复合模冲压，这样就提高了产品的生产率。通过充分利用现代模具制造技术对传统机械零件进行结构改进、优化设计、优化工艺方法能大幅度提高生产效率，这种方法对类似产品具有一定的借鉴作用。关键字：轴承盖；冲压；工序；生产批量；生产效率ABSTRACTIntroduced 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 l
