本文介绍了高速工具钢拉刀辊锻成形工艺,特别是完成了超硬高钴M42高速钢拉刀辊锻成形,进而为其它类型高速钢拉刀锻造提供了新的途径.辊锻工艺所控制的碳化物组织不均匀性、工艺塑性、加工余量和锻件表面质量等方面,都优于传统自由锻造工艺,而且它又具有明显的经济效益. In this paper, the high-speed tool steel broach roll forging process is introduced, especially the super-hard high-cobalt M42 high-speed steel broach roll forging forming, and thus for the other types of high-speed steel broach forging provides a new way. Of the carbide heterogeneity, plastic processing, machining allowance and forging surface quality, are better than the traditional free forging process, but it also has obvious economic benefits.
