Abstract
A billet scalper including a die assembly with a scalping die, a pressing mechanism with a stem member in axial alignment with the scalping die for pressing a billet thereinto, and a chip ejector located around the circumference of the scalping die and movable axially back and forth beyond a free end face of the scalping die to remove chips therefrom. The die assembly including the scalping die is movable between a position at the center of the scalper and an outer receded position to permit easy maintenance and service of the die assembly including replacements and cleaning of scalping dies. In a preferred form, the scalper is constructed integrally with an extrusion press to perform the billet scalping operation in timed relation with the extruding operation to shorten the time of press cycle.
