在日产货车百辆运动中,我们结合改进工具,把双边作业应用到各个工序上(从下料到切头),结果大大地提高了生产效率。目前它还只用在轴箱耳螺栓(如图1)上,提高生产效率1倍多,今后我们准备把它推广到其他锻件上。轴箱耳螺栓双边作业是在1/4吨蒸汽锤 In the one-day campaign of 100 trucks, we used improved tools to apply bilateral operations to each process (from loading to cutting), resulting in a dramatic increase in production efficiency. At present it is only used in the axle box studs (Figure 1), to improve production efficiency more than doubled in the future we are ready to promote it to other forgings. Billet bolts Bolt bilateral operation is in 1/4 tons of steam hammer
