一尽量采用模鍛工艺在成批生产情况下,尽可能利用模鍛工艺,如烏拉尔重机厂就有16台模鍛錘(0.5吨——7.5吨)。尽可能利用动力較小的設备做大鍛件。 1.分模鍛造法:可以用比原需压力少60～80％的設备。 6Ч23/30柴油机曲軸,原用9吨鋼錠,自由鍛,鍛件重4.8吨,零件淨重1吨;現用分段鍛造法,只用2.5吨鋼錠,鍛件重仅1.1吨。按模鍛计算,需28000吨的水压机,現用分段模鍛, A try to use forging process In the case of mass production, as much as possible the use of forging process, such as Ural Heavy Machinery Plant has 16 forging hammer (0.5 tons - 7.5 tons). Make use of smaller power equipment to forgings as much as possible. 1. Die forging method: you can use less than the original pressure of 60 to 80% of the equipment. Forged diesel engine crankshaft, original 9 tons of ingot, free forging, forging weight 4.8 tons, parts net weight 1 ton; now using segmented forging method, only 2.5 tons ingot, forging weight is only 1.1 tons. Press forging calculation, to be 28,000 tons of hydraulic press, the current segmented die forging,
