摘　　要：对连拉机组和盘拉机组所用的模具及润滑等拉拔条件进行了比较系统的分类研究,对一些不足之处进行了持续改进,使碳合结钢、合工钢、轴承钢连拔产品的拉拔精度普遍达到h10级,部分产品甚至达到h9级的要求。This paper systematically studied drawing conditions including lubrication and die arrangements installed on continuous drawing benches and coil drawing benches. Improvements were made to eliminate defects and shortcomings through the process flow, which made the drawing precision of carbon structural steel, alloy tool steel and bearing steel reach hlO, or even h9.

关 键 词：模具 拉拔条件 拉拔精度
