Abstract
PURPOSE: To prevent the impurities inclusion in the outer circumference of the thin walled large diameter pipe, by extruding the extrusion material toward the reversing die possessing the cavity to specify the outer diameter of the pipe, in order to extrude in the opposite direction to the advancing direction of the stem.
CONSTITUTION: The container 2 is parted toward the extrusion side of the container 2 from the reversing die 1 possessing the cavity 1A to specify the outer diameter of the extruded pipe, by a distance equal to the wall thickness of the pipe to be extruded. Then, the centers of the container 2 and the die 1 are aligned, and the extrusion material 3 (for example, the billet of copper, aluminum, etc.) held in the container 2 is extruded by the stem 5 through the dummy block 4 toward the die 1. Accordingly, the extrusion material 3 is extruded with a constant thickness by the clearance formed between the die 1 and the container 2, so as to change its direction at the wall of the die 1 oppositely to the advancing direction of the stem 5, and is extruded along the wall of the die 1. As a result, the extruded thin walled large diameter pipe product does not include the impurities like as oxides, etc., in its outer circumference.
