ABSTRACT:
In a punching machine, a yoke is supported on an eccentric section of the crankshaft. The yoke is designed to counterbalance the rotating forces. Both ends of the yoke are pivotably connected to connecting rods. Both connecting rods are pivotably connected, in turn, to a vertically-guided counterbalancing weight to counterbalance the oscillating forces.
