公称压力在100吨以下的中小型机械压力机,是工业部门最基本、最常见的板料加工设备,量大面广,通用性强。目前,国内制造这类压力机的专业厂与兼业厂多达百余家。但是,从50年代初国内开始制造这类压力机至今,在造型、结构及主要技术性能方面均无大的改进。我们多年来从事新建厂工艺设计与老企业技术改造的实践以及近年来 Nominal pressure of 100 tons in the following small and medium-sized mechanical presses, the industrial sector is the most basic and most common sheet metal processing equipment, a large amount of large, versatile. At present, the domestic manufacture of such presses professional factory and part-time factory as many as 100. However, since the beginning of manufacturing such presses in China in the early 1950s, no major improvements have been made in terms of shape, structure and main technical performance. We have been engaged in the design of new plant technology and the technological transformation of old enterprises for many years and in recent years
