摘要： An indirect extrusion press including a die assembly having a loose die detachably mounted on a die stem and axially movable relative to a billet container for extruding a billet through a die hole, and a die handling mechanism for transferring the die assembly between the press center and a position outside the press machine, the indirect extrusion press including a reduced diameter portion provided in the rear end portion of the die stem and defining a stepped wall portion; a loose die detachably mounted on the end face of the reduced diameter portion; and a detachable cleaning ring loosely fitted on the reduced diameter portion of the die stem in abutting engagement with the stepped wall portion and in axially spaced relation with the loose die, the cleaning ring being in sliding engagement with the inner periphery of the billet container in the extruding phase of the press operation to remove container shells. The press may further include as part of the die handling mechanism a chuck member for releasably gripping the loose die and cleaning ring and movable for transferring the die and ring in spaced relation between the press center and a retracted position outside the press machine, and a knocking member movable into the space between the loose die and cleaning ring at the retracted position to knock off container shells from a gap between the loose die and the cleaning ring.

摘要： 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.
