Abstract
PURPOSE: To eliminate the need for machining and finishing for removing the end of a blank by forming the hole parts of the dies and punch holder of a device of forming the end of a pipe joint having two threads of beadlike expanded parts from a tubular blank into the specific shape having no parallel portions.
CONSTITUTION: A pair of dies 1, 1' bisected in their diametral direction are inserted with a tubular blank 7 in their hole parts opened at their one end and a mandrel 6 supporting this end is inserted to the hole bottom side. Annular concave parts 4, 3 of a half bead shape opening in the end face and a perfect bead shape that follows this are formed in the hole parts. A punch 5 opposes to these and an annular concave part 4' of a half bead shape is formed to the above-mentioned end face of a punch holder 2 opposing to the dies and this connects to the concave part 4 on its end face side and its inside diameter side intersects with the outside circumference of the punch 5. The punch 5 is press-fitted into the blank 7 to bulge the elastic body 8 inserted in the blank in a diameter direction up to the bead part 3 and further the holder 2 press-contacts the dies to form two threads of bead-form expanded parts in the blank 7 by the perfect bead part consisting of the concave parts 4, 4'.
