Abstract
A cutting device for a direct extrusion press is intended to shear the residue remaining in the press cylinder after extrusion of the useful part of the billet to separate the residue from the extruded product. The device comprises a plane blade which is displaceable in a direction perpendicular to the extrusion axis between operative and inoperative positions and is guided in its displacement by guide means and displaced by drive means both of which are mounted on the slide block of the press.
Claims5
A cutting device for a press for the direct extrusion of metal billets, the press comprising a longitudinally movable cylinder for receiving a billet, and a bed in which a transversely displaceable slide block is mounted, the slide block carrying a die, said cutting device being arranged to shear the residue remaining in the cylinder after extrusion of the useful part of a billet, to separate the residue from the extruded product, and comprising:
- a plane blade which is displaceable in a direction perpendicular to the axis of extrusion between an inoperative position away from the die and from the product during extrusion and an operative position in which cutting takes place when the cylinder has been moved away from the die at the end of an extrusion operation;
- guide means for guiding said blade in its displacement;
- drive means for displacing said blade and for applying a cutting force to said blade;
- and
- wherein said guide means and said drive means are mounted on the slide block, end parts of said guide means being disposed near the die to guide said blade perfectly during the cutting operation.
