过去,我们在锻造10吨提引环芯轴(图1)时,打不出R62外形,是以气割做出来的。气割后有小裂缝,尺寸65处台阶也锻不出,造成很大圆角。下料重量达37公斤。后来,老工人李振元同志制造了一套工具,在原有的设备上锻出了质量好的锻 In the past, when we were forging a 10-ton index ring mandrel (Figure 1), we could not make the R62 profile and were made by gas cutting. Gas cutting small cracks, the size of the 65 steps can not be forged, resulting in a very large fillet. Cutting weight up to 37 kg. Later, the old worker Comrade Li Zhenyuan made a set of tools, forged the good quality forging on the original equipment
