摘要
在我国,冷压模具的研究及制作技术与发达国家相比,起步比较晚,且该项技术多应用于铁矿领域中。在没有研发出分级机螺旋叶片冷压模具的时候,我国矿山领域使用的分级机螺旋叶片,或采用传统加热锤打成型的螺旋叶片,或从国外引进零件,传统方法制造效率低、环境恶劣,国外引进费用高、资金周转的时间长。通过对分级机螺旋叶片的分析,通过其制作的过程以及冷压模具形成以后所具有的优点对分级机螺旋叶片冷压模具的制作进行探究。
Compared with developed countries,the research and production technology of cold press mold in our country started relatively late,and this technology is mostly used in the field of iron ore.When there were no cold press dies for the spiral blades of classifier,which were used in the mining field in China,formed by traditional hot hammering,or imported spare parts from abroad.Traditional methods have low manufacturing efficiency and harsh environment.Foreign introductions get high cost and long period capital turnover.This paper analyzes the spiral blades of classifier,to explore the formation of the cold press dies of spiral blades,through the manufacturing process of spiral blades and the advantages of the cold press mold.
