我厂广大职工高举“鞍钢宪法”伟大红旗,实行“工人、干部、技术人员”,“工厂、学校、科研单位”三结合,在一机部机电所、上海交通大学及其它兄弟单位的大力协助下,对凿岩机中的部分零件进行了冷温挤压工艺试验,得到了一些效果。通过实践证明,采用挤压工艺制造零件,具有节约原材料,生产效率高等优点,并且提高了零件的机械性能、加工精度和光洁度。 I plant a large number of workers held high the “Great Red Flag of the Ansteel Constitution”, the implementation of the “workers, cadres and technical staff” and “factories, schools, research institutes,” the three in a mechanical and electrical units, Shanghai Jiaotong University and other fraternal units of the strong assistance Under the rock drill part of the cold temperature extrusion process test obtained some results. Practice has proved that the use of extrusion manufacturing parts, with the advantages of saving raw materials, high production efficiency, and improve the mechanical properties of parts, machining accuracy and finish.
