Abstract
The top and bottom ends of a pivoting lever, which is pivotable in the middle, are rotatably connected with a supporting component and a ram, respectively. A shuttle component is linked with the pivot point of the pivoting lever. The shuttle component drives the pivoting lever forcing it to pivot, and when the shuttle component reaches the midpoint of the stroke the pivoting is fully extended. The shuttle component is shuttled by way of a crank, utilizing a servomotor as the drive source. The ram drives the punching tool and is held by the frame in the way that it can readily make the up and down motion.
