Abstract

An adjustable shear blade blanking press with an automatically centered blank pusher has a guide over which a strip of sheet material to be cut into blanks can be guided device extending a cross the guide transversely to the guide in a guide direction, at least two side by side shear blade direction and spaced in the guide direciton, the shear blade devices being pivotally mounted for adjustment of the positions thereof between a position perpendicular to the guide direction and a position at an angle to the guide direction and for adjustment toward and away from each other. A pusher is provided for pushing a cut blank laterally of the guide direction and is adjustably mounted on one side of the guide for reciprocal movement parallel to the guide direction. An automatic center mechanism is connected to the pusher and to the shear blade devices for shifting the position of the pusher to a location midway between corresponding one ends of said shear blade devices in response to the pivoting movement or longitudinal movement of the shear blade devices as the shear blade devices shift positions.
