内容記述 | Tests were perfomed on the wearing and tearing of double-edged rectangular punches and on the shearing of 0.25 mm thick Kovar sheets by using the punches. Ten rectangular punches with the slenderness ratio ranging from 8.7 to 80.7 were used in the experiment. The wearing and tearing of the cutting edges and the bending and breakage of the punches were examined. The unbalanced side shearing force which produced local abnormal wears, breakages, and other defects of the punches and their edges maight have been caused by scraps remaining on the die face, the uneven wears on the cutting edges, and the local uneveness in tool clearance and work material. Such abnormal wear and breakage can be prevented by making a smaller clearance between the blank holder and the punch than that of the clearance between the punch and die. By observing the defective edges of the punches and the dies using an X-ray microanalyser, it has been made clear that particles of the work material have adhered to the side suface of the tools. From this observation it can be conclude that the tool wear in this case belongs to the adhesive wear. | |||||||||
