轴挡(手推车砂挡)其成品规格如图1,材料为Ст15。原是用直径38公厘元钢在六角车床上进行切削加工。每台机床每班平均生产400个左右,故很难完成生产计划,而原材料的浪费也很严重。在大闹技术革命运动中,我们大胆的采用了先进的冷锻工艺来代替金属切削加工。 Axis block (trolley sand block) the finished product specifications shown in Figure 1, the material for Ст15. The original is 38 mm in diameter steel in the six-axis lathe for cutting. Each machine has an average production of 400 or so per class, so it is difficult to complete the production plan, and the waste of raw materials is also very serious. In the technical revolution movement, we boldly adopted the advanced cold forging process instead of metal cutting.
