Abstract
A turret punch press includes rotatable upper and lower turrets, a striker which is vertically movable for striking a punch, a plate positioning device for moving and positioning, in the X and Y directions, a plate workpiece supported on a work table, and a tool changing device, wherein a punch holder magazine and a die holder magazine supporting respectively a punch and a die to be installed on the upper turret and the lower turret to replace the punch and die in use, are provided adjacent to the upper and lower turrets. The punch changing position on the upper turret is below the punch holder magazine, and the die changing position on the lower turret is above the die holder magazine. The tool changing device is positioned on a vertical line between the punch and die changing positions so that the punches and dies can be changed by a direct linear operation.
