Abstract
PURPOSE: To manufacture a metallic pipe having a truly round inner diameter and an optionally shaped outer diameter, by drawing a round pipe blank with an external die having an optionally shaped inner surface and a round column shaped internal die.
CONSTITUTION: The inner surface of an external die 1 is formed into an optional shape except a true round; an internal die 2 is formed into a round column shape and is attached to the tip of a mandrel 3. A round pipe blank 4 is chucked by a carriage 5 which is then withdrawn so as to pull the pipe blank 4 in the drawing direction; hereby, the outer diameter, that is the outer surface, of the pipe blank 4 is formed into such a desired shape as a hexagon, an octagon, etc., for example, by the inner sueface of the external die 1; at the same time, the inner diameter of the pipe blank 4 is always kept at a truly round shape by the round column shaped internal die 2; the desired metallic pipe is thus manufactured by the drawing process.
