目前有不少单位195型柴油机曲轴采用球墨铸铁铸造而成,在满足其工艺性能要求的情况下,材料是以铁代钢,而制造工艺方面比胎模锻造简单,并且生产效率高,对于小厂来讲更易上马。但是,由于有不少单位没有掌握此项技术,仍然采用锻造曲轴。为了互通情报,现把我厂在胎模锻造曲轴方面的点滴改进介绍如下。我厂只有一吨夹杆锤和750公斤空气锤,曲轴在上述设备上进行胎模锻造。旧 At present, many units of 195 diesel engine crankshaft cast from ductile iron, to meet the requirements of its process performance, the material is made of iron steel, and manufacturing process than forging simple, and high production efficiency, for small In terms of plant easier to launch. However, as many units do not have this technology, they still use forged crankshafts. In order to exchange information, now I plant in the mold forging crankshaft bit by bit improvement described below. I plant only a ton of clamp hammer and 750 kg air hammer, crankshaft in the above equipment for tire forging. old
