图1所示为我厂生产的1Cr18Ni9不锈钢杯形零件成,不仅生产效率低,劳动强度大,而且加工余量也大,浪费了不少材料。为了改变这种状态,我们于1980年初对该零件进行了热冲挤工艺试验。经过技术人员、工人师傅的共同努力,终于在560公斤空气锤上进行热冲挤工艺获得成功,并投入了批量生产。仅 Figure 1 shows the 1Cr18Ni9 stainless steel cup-shaped parts produced by our factory. Not only the production efficiency is low, the labor intensity is large, but also the machining allowance is also large, which istes a lot of materials. In order to change this state, we conducted a hot-extrusion test on the part in early 1980. Through the joint efforts of technicians and workers, the success of the hot impact extrusion process on the 560 kg air hammer was finally put into mass production. only
