Abstract
PURPOSE: To effectively manufacture the bellows pipe without damaging or deforming of pipe by expanding the pipe with the flexible rubber material and with the chuck type component which is combined with the above and drawing the chuck type component to the radial direction after then.
CONSTITUTION: The core metal 11 is inserted to the pipe body 10 which is formed with the expanded bead 9 of prescribed height and of mountain type cross section, and is made to the state of that the outer circumference of the core metal 11 is in contact with the bottom part of the valley part 9a of the expanded bead 9. The chuck type components 7a-7d which is divided around the axial center 6 is inserted in the valley part 9a of the expanded bead 9. The chuck type components 7a-7d is pressed to the pipe body 10 which is supported with the core metal 11 and also the pipe body 10 is pressed to the axial direction and is pressed respectively in contact with the recessed shape die 12 of cross section Ω type formed at both side of the chuck type component 7a-7d, the half of Ω type bead is formed respectively on the opposite side beyond the valley part 9a of the pipe body 10. The chuck type components 7a is moved to the Y direction and passed out. By moving the pipe body 10 by 1 pitch, the same process is repeated and the expanded bead 9 is formed to the perfect Ωtype bead.
