Abstract:
1. A device for removing fine blanking parts, which have been precision punched out from a blank, from a fine blanking tool of a fine blanking press having a frame, a ram, an ejector, and tool parts, the tool parts including an upper tool part and a lower tool part, said fine blanking tool being one of said tool parts, the device comprising: a direct drive fixed to a frame of the fine blanking press, the direct drive comprising a drive shaft, an arm, a bracket and a rapid-action coupling; and a cross slide coupled to said arm via the rapid-action coupling and bracket; and wherein said cross slide has a transverse movement relative to a working direction of the tool parts, so as to move into the working area between the upper and lower tool parts when one of the tool parts opens and so as to move out of the working area with one or more of the fine blanking parts when one of the tool parts closes; wherein the direct drive converts a rotating motion of the drive shaft into a linear motion of the cross slide so as to achieve said transverse movement, wherein the direction of the linear motion reverses, in dependence on a stroke of the ram, between a rear stop position and a front stop position of the cross slide in the working area; wherein the cross slide comprises a base plate and a parts plate, the parts plate movable between the front stop position and rear stop position while being guided on rails positioned on the base plate; and wherein the parts plate comprises a mask having a plurality of openings with contours and geometries corresponding to a geometry of said fine blanking tool and a cutting geometry of the fine blanking parts, said parts plate receiving into said plurality of openings the fine blanking parts pressed into said plurality of openings by said ejector so as to hold said fine blanking parts during a distance portion of said transverse movement for unloading the fine blanking parts from the fine blanking press.
