摘要：PURPOSE:To offer a constricted portion forming machine able to form a constricted portion of narrow diameter at every constant distant position on a continuous slender raw material in small space by rotating a forming tool around the central axis of the raw material with a rotation mechanism while bringing the forming tool clo to the raw material with an approach and paration mechanism. CONSTITUTION:A ring body 45 is moved to one end as an unit by the operation of a slide mechanism. The movement of the ring body 45 is converted to a radial movement by the wedge effect of tilted planes 41, 48, and a roller 39 supported on a slide body 32 is moved also to approach a raw material S. At that time, the rotation of a sun gear is transmitted to a rotation block 13 through a pinion, a belt 64 and a pulley 63. Thereby the rotation block 13 is rotated around its axis with a constant velocity, and the slide body 32 and the roller 39 are rotated around the central axis of the raw material S. Then the roller 39 is pushed in the raw material S to deform it, and a constricted portion K of ring-shaped groove G of cross ction shaped like the charactor V can be formed.
