| Abstract | In this research work,damage ofpunch/die tools in a steel wire rod shear cutting was investigated.The tools (punch and die)usedin a steel wire rod(JIS SCM420)cutting ranging from 50,000 to 150,000 cutting shots were collected fortheinvestigation. Experimental results showedthat the main damage of the tools at the sheared zone was tool edge chipping. The edge of the die was chipped severely when passing 150,000 cutting shots. To investigate the cutting characteristics of the wire rod by the damaged tools, the tools were applied for a shear cutting test using a developed shearcuttingtool holder. It was found that the damage of the tools did not remarkably affect the cutting load resistance of the wire rod. However, when cutting the wirerod with the higher-cutting-shot tools, the quality of the sheared edge deteriorated. Namely, the sizes of the rollover and the burr at the sheared edges of the wire rod tended to increase. |
