Abstract
PURPOSE: To simply form the taper pipe provided with high accurate spiral groove at inner surface, by applying the drawing work to the pipe blank after forming the spiral groove at inner surface of the pipe end.
CONSTITUTION: The spiral groove 2 in suitalbe pitch and length is formed at the inner surface of the end of the pipe blank 1 by the cutting work or the plastic work; after that, the end of the pipe blank 1 in the same length as that of the spiral groove 2 is subjected to the drawing work; hereby, the taper pipe 3, provided with the spiral groove 2' in about constant depth at the inner surface of the end of the pipe 1', is formed. Since this forming method jointly uses the cutting work or the plastic work and the drawing work, the spiral groove 2' is simply formed at the inner surface of the taper pipe 3 which hereby becomes suitable for the mass production.
