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.

Dependent claims

A turret punch press comprising:

a rotatable upper turret for detachable supporting a punch;
a rotatable lower turret for detachably supporting a die which processes a plate workpiece in collaboration with the punch;
a striker with vertical movement for striking a punch which has been indexed in a work position;
a plate positioning device for moving and positioning, in the X, Y directions, the plate workpiece, supported on a work table;
and
a tool changing device for detaching and changing the punch and die on the upper and lower turrets, respectively;
characterized by
a punch holder magazine, adjacent to the upper turret, for supporting a punch which is to be detached and changed at the upper turret;
a die holder magazine, adjacent to the lower turret, for supporting a die which is to be detached and changed at the lower turret;
wherein:
a punch changing position on the upper turret is below the punch holder magazine, a die changing position on the lower turret is above the die holder magazine, and 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, and a semicircular auxiliary table with a support member for supporting a plate workpiece is provided on the side of the lower turret.
