Extrusion press with a billet scalper.

摘要

A billet scalper including a die assembly [7] with a scalping die [6], a pressing mechanism [8] with a stem member [12] in axial alignment with said scalping die [6] for pressing a billet [B] thereinto, and a chip ejector [18] located around the circumference of the scalping die (6) and movable axially back and forth beyond a free end face of said scalping die [6] to remove chips [17] there-from. The die assembly [7] including the scalping die [6] is movable between a position at the centre of the scalper and an outer withdrawn position to permit easy maintenance and service of the die assembly [7] including replacement and cleaning of scalping dies [6]. 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.
