湘潭市锻造厂生产各种规格(φ40～120mm)的锻钢球,年产量达3000～4000 t。生产工艺是用1.2～1.3m长的圆钢或方钢经加热到锻造温度后,在100 t冲床上热切下料。下料模的上、下刀片是平刃口,用固定式的压料装置压料(实际未压着),由于间隙过大,刃口形状与坯料不匹配,剪切后的坯料, Forging factory in Xiangtan City, the production of various specifications (φ40 ~ 120mm) forged steel ball, the annual output of 3000 ~ 4000 t. Production process is to use 1.2 ~ 1.3m long round or square steel heated to forging temperature, the 100 t punch eagerly cut material. The upper and lower blade of the blanking die is a flat edge, which is pressed by a fixed pressing device (actually not pressed). Because the gap is too large, the shape of the cutting edge does not match the blank, and the cut blanks,
