Abstract

Punching or piercing is among the oldest and most frequently used sheet metal forming process. The main
objective of this study is to increase the punch life. In this study effect of different punch shear on punch life is
evaluated experimentally on 30 tones Mechanical power press. In this study piercing process of ø20mm hole on 6 mm
thick flat strip of Low carbon steel AISI 1020 is carried out on 30 tones mechanical power press with flat bottom
punch. The main problem in this operation is punch broken frequently when using flat bottom (without shear) punch.
Which results in lower punch life and productivity. Hence there is need of designing a new punches with single shear,
double shear, and combined flat & double shear which gives higher punch life and productivity. Also the reason for
the breakdown has been analyzed and inspected by the method of Fish bone diagram.
