我厂在制造铝容器时,对如图1所示的铝容器下部的球鼓的成型,过去是采用人工锤打的办法,不但劳动条件差、强度大,而且效率低、质量差。后来我们在铝封头爆炸成型的基础上,大胆尝试,经过几次试验,终于用爆炸法代替了手工操作。其优点是:1.操作工艺简便,容易掌握:仍将原手工操作用的铸铁下胎垫在容器 I plant in the manufacture of aluminum containers, as shown in Figure 1 below the aluminum container forming the ball drum, the past is the use of artificial hammering approach, not only poor working conditions, strength, and low efficiency, poor quality. Later, on the basis of explosion molding of aluminum head, we tried boldly and after several tests, we finally replaced the manual operation with the explosion method. Its advantages are: 1. The operation process is simple, easy to grasp: still the original hand-operated cast iron under the tire in the container
