摘　　要：以成形指针的模具零件为研究对象,对用不同材料Cr12MoV钢和7Cr7Mo2V2Si钢制作的小孔凸、凹模的磨损量和刃磨寿命进行了研究。结果表明:用7Cr7Mo2V2Si钢的模具零件比Cr12MoV钢的正常磨损阶段更长,模具零件的平均刃磨寿命可延长50%,具有明显的优越性。Taking the die parts for forming needle as research object, the wear extent and service life of the punch and matrix with different materials of Cr12MoV steel and 7Cr7Mo2V2Si steel were studied. The results showed that the service life of 7CrTMo2V2Si steel die parts was increased as much as 50% than Crl2MoV steel.
