ABSTRACT:
An apparatus for punching a workpiece has a stationary frame, a longitudinally extending row of horizontally spaced and upwardly facing different dies fixed on the frame below a horizontally elongated punching station, at least one horizontal and stationary rail fixed on the frame, and a punch carriage displaceable horizontally along the rail above the station. A turret rotates about a horizontal turret axis on the carriage and carries a plurality of radially outwardly directed different punches angularly spaced about the turret axis. A positioning unit is operatively connected between the carriage and the frame for displacing the carriage through a plurality of positions in each of which the turret axis is above one of the dies. An indexing unit angularly displaces the turret about its axis through positions in each of which one of the punches is facing down in the station toward the respective die. An actuator vertically displaces the turret and its axis on the punch carriage when one of the punches is above and facing down in the station at the respective die and thereby punches a workpiece resting on the die.
