Butt shear with butt knocker

In an extrusion press wherein a butt dislodging means is movable transversely with respect to the extrusion axis of the press to dislodge the butt of a metal billet from the face of an extrusion die subsequent to an extrusison operation, said butt dislodging means comprising:

• guide means carried by said press;
• a slide carried on said on said guide means for selective reciprocal movement along said guides transversely of the extrusion axis of said press;
• a shear blade carried by said slide for movement with said slide along a shear plane that is coincident with the face of such a die for shearing such a butt from the face of such an extrusion die;
• and
• elongated butt knockoff means carried by said slide and including an elongated member which is selectively movable with respect to said slide along a line of motion which passes in proximity to said shear blade and converges with said shear plane.

In an extrusion press for the extrusion of aluminum forms from aluminum billets, a billet butt removal apparatus comprising:

• a slide carried by guides for reciprocal movement perpendicularly to the axis of extrusion of such an extrusion press;
• first motive means for selectively moving said slide along said guides;
• said slide including a forward end portion which is selectively movable into and out of an overlapping relationship with the extrusion axis of such press upon actuation of said first motive means;
• a shear blade carried by said forward end portion for movement therewith along a shear plane;
• means for positioning a die and an attached butt end of a billet with the interface therebetween on said shear plane;
• a butt knocker means carried by said slide and movable in concert therewith;
• said butt knocker means including an elongated member which extends on an axis in converging relationship with said shear plane;
• and
• said butt knocker means including second motive means which is cooperable with one end of said elongated member to propel said elongated member on said axis for selectively moving the opposite end of said elongated member into proximity with said shear plane.
