Effect of Tool Shape on Galling Behavior in Plate Shearing

Abstract:

Finish blanking is one of the precision shearing processes and it has some features such as the formability of a high ratio of the burnished surface, lower surface expansion ratio of the burnished surface. The purpose of the present work is to clarify the effect of the tool shape in finish blanking on galling behavior. A high-tensile-strength-steel plate with a thickness of 6mm is used in the present paper. The edge shape of punch is changed while the clearance is kept to 12%t. Galling is observed except for the PW punch with the edge angle of 30 degrees at the first shearing operation. In the case of the PW punch with the edge angle of 30 degrees, galling cant be found clearly even when the shearing number increases until 20. The burnished surface has a glossy part with the clean metal for the punches except for the PW punch with the edge angle of 30 degree. It is found that the glossy part is generated after fracture occurs at the punch edge and then causes galling.
