加工图1所示的轴承盖零件,常用的方法是冷冲压。采用冲压工艺需专门设计、制造落料、冲孔拉延两套冲模。这样不仅周期长,而且费用高,对单件批量小的生产单位来说是不经济的办法。针对这一情况,二汽车箱分厂车工李盛桓专门制做了一套在车床上加工轴承盖的胎具。零件制做过程如下:先根据零件展开尺寸剪切板料。将剪得的板料放入图2所示磁铁5与本体2之间, Machining the bearing cap parts shown in Figure 1, the common method is cold stamping. The use of stamping process to be specifically designed to create blanking, punching two sets of drawing die. This will not only be long-term but also costly, which is not an economical solution to small batch production units. In view of this situation, the second car box factory workers Li Shenghuan specialized system made a set of processing in the lathe bearing cover of the car. Part manufacturing process is as follows: First, according to the size of parts to cut the sheet size. Will cut the sheet into the magnet 2 shown in Figure 2 and the body 2,
