我厂钢球冷镦模具 (以下称冷镦模 )的材料为ＧＣｒ1 5轴承钢 ,加工一定数量的钢球后 ,冷镦模的工作部分出现变形 ,不能正常使用的冷镦模 ,作为废钢处理。为降低生产成本 ,开展了钢球冷镦模再利用的探索。一副冷镦模包括切料模、切料刀板、冲模和压模 ,再利用的修复分述如下。1 Cold-heading steel ball mold factory (hereinafter referred to as cold heading die) for the GCr1 5 bearing steel, after processing a certain number of steel balls, the cold heading die part of the work of deformation, can not be used normally cold heading die, as scrap processing . In order to reduce production costs, the steel ball cold heading die reuse exploration. A cold heading die including cutting die, cutting blade, die and die, the reuse of the repair points are as follows. 1
