ABSTRACT:
The turret punch press has a body frame (3); a ram (51) for striking a punch (41) to punch out work (W) in cooperation with a die (35); an upper turret (39) rotatably mounted on the body frame and having a plurality of punches (41), any desired punch being selectively located at a punch area (A1); and a lower turret (33) also rotatably mounted on the body frame and having a plurality of dies (35), any desired die mated with the desired punch being selectively located at the same punch area (A1). In particular, the upper turret (39) is formed smaller in diameter than the lower turret (33), and further the upper turret (39) is dislocated eccentrically from the lower turret (33) toward the punch area (A1) to provide an open die exchange area (A2) over a part of the lower turret (33). Or else, the upper turret (39) is formed with a cutout portion (53) to provide an open die exchange area (A2) over a part of the lower turret (33) when the upper turret is disposed concentrically on the upper turret (39). In addition, since a first die delivery device (85) is disposed on the body frame (3) and at the die exchange area (A2) to minimize the load applied to the die exchange arm (65), the die (35) can be moved by the die exchange arm to and from a die mount hole (37) of the lower turret (33) at high die exchange speed and precision, thus improving the die exchange efficiency.
