Paper Title:
Study on Working Hardening for the Sheet with Different Hardening Index by Fine-Blanking with Negative Clearance
  Abstract

The hardening layer of blanking boundary could enhance structure intensity and wear resistance of blanking work piece evidently. Therefore it could enhance fatigue strength and the working life of work piece greatly. This paper carried through fine-blanking with negative clearance processing experiment for the sheet with different hardening index and measured the blanking force and the punch stroke relations curves. The micro hardness of the blanking work pieces sheared surface were measured by Vickers Hardness instrument(MH-6), which obtained the relations curves of punch stroke and the micro hardness of the blanking work pieces. The level of working hardening were compared with different hardening index materials by fine-blanking with negative clearance, and the blanking work pieces working hardening were enhanced evidently by fine-blanking with negative clearance.
