苏联机床与工具制造业中,进行了很多技术革新,在节约金属、提高劳动生产率和降低产品成本等方面有很大的效果。 锻压和热处理工艺亦有很大的发展。 一、锻压生产 1.滚锻 滚锻系金属在热状态时用滚锻模锻成要求的零件毛坯(图1)。 滚锻模系按各种不同零件的形状进行设计的。滚锻 In the Soviet machine tool and tool manufacturing industry, many technological innovations have been made, with great effects in saving metals, improving labor productivity and reducing product costs. Forging and heat treatment process also has great development. First, the forging production 1. Roll Forging Roll forging Department of metal in the hot state with forging die forging into the required parts rough (Figure 1). Forging dies are designed according to the shape of the various parts. Roll forging
