挤出平模头自动抛光技术研究

Study on Automatic Polishing Technology of Extrusion Dies

为了提高挤出平模头的工艺稳定性、产品的一致性及生产效率,本文对挤出平模头自动化抛光技术进行了初步研究。简要地介绍了课题研究的背景和意义;从抛光机理出发,针对挤出模具钢进行了可加工性试验研究;研究结果表明,采用化学机械抛光的方法加工所获得的加工表面能够达到平模头产品的粗糙度要求。最后,根据平模头的尺寸要求和工艺要求,研制出了一种能够实现大尺寸工件自动抛光的装置。

In this paper, in order to enhance process stability of extrusion dies, product consistency and improve production efficiency,a preliminary study has been investigated about automatic polishing technology of extrusion dies. This paper briefly described the research background and significance. A machinability about the steel of extrusion dies test based on polishing mechanism has been made. The text results show that the surface quality of workpiece manufactured by CMP can meet the demands of extrusion dies. Finial, according to the size and the technological requirments of extrusion dies, a kind of automatic polishing equipment is developed for big-size workpiece.
