轴承座冲压模具设计
摘要
本课题的主要内容是设计一副生产轴承座的级进模，包括拉深、冲孔和落料。模具中采用先拉深，再冲孔，落料。由于该模具的凸模较多，工件的精确定位是模具设计的重点，为了保证制件的精度，选用工件上冲孔后留下的Φ8.8孔作为导正销孔，在落料凸模上设置导正销进行导正。模具采用弹压卸料，下出件方式，提高了工作效率。材料的利用率为75.71%，材料的利用率较高，节省了材料，提高了经济效益。
但是由于制件的尺寸较大，导致模架尺寸也相应较大，给冲压设备的要求较高，且级进模对模具的导向精度要求高，冲压时难免出现废品。另模具的制造成本也比较高，给模具的大量生产带来困难。通过不断的实践以后可以改善以上出现问题，使模具能够得到普遍应用。
