不久前,我们接受了锻造如图1所示的齿套零件的任务。由于批量小,我厂又缺乏扩孔机、压力机和摩擦压力机等设备,不可能采用闭式模锻。只好在自由锻锤上锻造,考虑到采用合模锻造或开式模锻,都需要增加去飞边工序,同时也浪费材料,为此,我们设计了无飞边镶块锻 Not long ago, we accepted the task of forging the toothed part shown in Figure 1. Due to the small batch, I plant the lack of reaming machines, presses and friction presses and other equipment, it is impossible to use closed die forging. Had to forging in the free forging hammer, taking into account the use of mold forging or open die forging, need to increase the flash process, but also a waste of materials, for which we have designed without flash insert forging
