本论文主要介绍了螺母板支座的冲压工艺分析，冲压方案的确定及最佳工艺方案的选择，在保证冲压件满足各种性能要求的前提下使其具有最大的经济性； 本文对零件进行了工艺分析和必要的工艺计算。该工件的成型包括落料、冲孔及弯曲三个工序。经分析比较确定最终的工艺方案为：落料冲孔工序复合、冲孔、弯曲。根据确定的工艺方案，最终设计出了落料拉深复合模、冲孔模、弯曲模三套模具，并用 CAD 完成了装配图和零件图的绘制。关键字：冲压；落料；冲孔；弯曲；模具设计 Nut Plate Bearing Stamping Process and Design of the Die ABSTRACTThis paper introduced the analysis of the stamping process of the nut plate bearing, determination and selection of the best stamping technology program. Under the premise of ensuring stamping parts to meet a variety of performance requirements, greatest economic can be got. Process analysis and necessary calculation were made,the results showed that blanking, punching and bending processes should be done to obtain the workpiece.After analysis and comparision ,the best of all kinds of possible stamping schemes listed is:compound process of blanking and punching, punching,bending. In accordance with the established technology program,three sets of dies were completed in this paper : compound die of blanking and punching, punching die,bending die.At last ,AutoCAD drawing software was used to finish some pieces of 2D assembly-die drawings and detail drawings.Key Words : stamping, blanking, punching, bending, mold design 1 前 言 板料成形通常称为冲压或冷冲，即在室温下，利用安装在压力机上的冲压模具（冷冲模、冲模）对材料（板料、条料或带料）施加压力，使其产生分离或发生塑性变形，从而获得所需形状和尺寸、具有一定力学性能的零件的一种压力加工方法。 冲压模具是指在冷冲压加工中，将材料（金属或非金属）加工成零件（或半成品件）的一种特别工艺装备。冲压成型加工必须具备相应的模具。模具是技术密集型产品，其制造属于单件小批量生产具有难加工、精度高、...
