ABSTRACT:
A punch press that provides an arrangement of a motor and a crank mechanism so that the motor does not project far from the side of a frame. The punch press includes a servo motor, a ram which drives a press tool, a crank mechanism which converts a rotating motion transmitted to a crank shaft into an elevating and lowering operation of the ram, and a drive transmitting mechanism which transmits rotation of the servo motor to the crank shaft while reducing rotation speed. The servo motor is next to the crank mechanism and its rotating axis is parallel to the axis of the crank shaft. The drive transmitting mechanism includes servo motor side gears joined to respective output shafts of the servo motor. The servo motor side gears respectively engage, directly or via intermediate gears, with crank side gears joined to the crank shaft.
