1、轴承盖落料、拉深、冲孔复合模28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
2、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；生产效率全套图纸，加28ABSTRACTIntroducedtocarrythebearingcovercoldhurtletopresstotakeshapetheprocess,passbytothebatchquantityproduction,sparepartsquantity,thesparepartsstructureandusagerequestofcarrythebearingcoverofanalysis,study,accord
