Abstract
PURPOSE: To provide a cut-off pipe of high accuracy in inside and outside diameters and shape, by shearing off a pipe while gradually expanding it and by thereafter effecting restrictive ring rolling on the pipe.
CONSTITUTION: A cutting-off die 10 and an outside diameter correcting die 15 are fitted in a first main shaft 11. A pipe 12 is then set. A mandrel 13 supported by a second main shaft 14 is inserted into the pipe 12. The second main shaft 14 is elevated perpendicularly to its axis by the rotation of the first main shaft 11. The pipe 12 is sheared off by the die 10 and the mandrel 13. The sheared-off pipe 12' is expanded. The inside and outside diameters of the pipe 12' are corrected by the die 15 and the mandrel 13.
