锻造生产是利用金属的塑性,在高温高压下,使金属变形成为所需要的形状,改善金属的组织,以获得优良的机械性质,并且使金属滑耗降低到最低程度。根据这个要求,我厂改进了单缸汽油机曲轴的初锻工作,现在将它的经过情形介绍如下,供大家参致。 Forging is the use of metal plasticity, under high temperature and pressure, the metal deformation into the desired shape, improve the metal organization, in order to obtain excellent mechanical properties, and to minimize metal sliding loss. According to this request, our factory improved the preliminary forging work of single-cylinder gasoline engine crankshaft, and now it will be introduced as follows for your reference.
