我厂生产的起重机液压传动系统需用许多种管路连接件。几年来这些零件一直用机加工方法制造,不仅占用了许多机床,消耗了许多钢材,而且质量不够稳定,因此一直是我厂生产中的一个关键。汽吊车间广大职工在党支部的领导下,总结了过去存在的差距,并向有关兄弟厂学习,经过充分讨论研究,确定用冷挤压工艺解决管
The hydraulic drive system for cranes produced by our factory requires many types of pipe connections. These parts have been manufactured by machining methods for several years. They not only occupy a lot of machine tools, consume a lot of steel, and are not stable enough in quality. Therefore, they have always been a key factor in our production. Under the leadership of the Party branch, the majority of the workers in the steam lift workshop summarized the gaps that existed in the past and learned from related brother factories. After thorough discussion and research, it was determined that the cold extrusion process would be used to solve the problem.
