PURPOSE: To lower the height between the bottom face and parts output port of a parts manufacturing machine by the height of an elevating/driving means by disposing the elevating/driving means for the movable metal mold of a punching device above a transfer device, and connecting the elevating/driving means to the movable metal mold through a driving force transmitting means.
CONSTITUTION: The elevating/driving means 18 of a punching device 4 is disposed being spaced from the operating axis of a movable metal mold 17, utilizing a space above a transfer device 3 so as to elevate/drive the movable metal mold 17 intermittently by the elevating/driving means 18 through a driving force transmitting means 20. As a result, the height between the bottom face and parts output port 19 of a parts manufacturing machine can be lowered by the height of the elevating/driving means 18.
