ABSTRACT:
A hydraulic puncher includes a puncher body housing an actuator, a reciprocal ram shaft and a punch holder having one end rotatably connected to the end of the ram shaft. Punches are arranged in the other end of the punch holder. A C-shaped frame has an opening opened perpendicularly to the axis of the puncher body and one end integrally connected to the puncher body. A die holder has one end removably connected to the other end of the C-shaped frame and dies are connected to the other end of the die holder and each having holes for receiving the punches. A first connecting unit is provided for fixing the punch holder to the ram shaft so as to selectively cause the punch holder to extend toward the front side of and crosswise of the puncher. A second connecting unit is provided for fixing the die holder to the other end of the C-shaped frame so as to selectively cause the die holder to extend toward the front side of and crosswise of the puncher.
