第一机械工业部情报所《技术革新简报》第七十五期发表了《冷挤压的现状及发展中的问题》。文中论述了国内外冷挤压的现状,提出发展中的问题并介绍了新的冷挤压方法。现摘要介绍如下。冷挤压是压力加工中的一种先进工艺。冷挤压零件的精度能达到3级,表面光洁度能达到(?)6～(?)9。冷挤压生产率比切削加工要高几倍甚至几十倍,材料利用率达70％～80％以上。挤出的零件机械性能好。
The Seventy-fifth Issue of the Technical Innovation Bulletin issued by the First Machinery Industry Institute Intelligence Unit published the Current Situation and Problems in Cold Development. This paper discusses the current situation of cold extrusion at home and abroad, puts forward the problems in development and introduces a new cold extrusion method. The summary is as follows. Cold extrusion is an advanced process in pressure processing. Cold extrusion parts can reach the accuracy of 3, the surface finish can reach (?) 6 ~ (?) 9. Cold extrusion productivity than cutting several times or even several times, material utilization rate of 70% to 80%. Extruded parts have good mechanical properties.
