Abstract
PURPOSE: To produce pulleys of special shape without largely modifying the standard production facility, by performing preliminary and final forming by pressing a roller of specified shape to the peripheral wall of cup-shaped material which is supported and rotated between two rotary molds of specified shape.
CONSTITUTION: A metal cup-shaped material 1 is supported by rotary molds for preliminary forming 2, 3 in the stepped part 1a and opening part 1b thereof, which are rotated together integrally, and while shortening the interval between the molds 2, 3, a roller for preliminary forming 4 is pressed against the peripheral wall 1c. By narrowing the gap between a tapered forming face 2a and a concave relief part 4a which is approximately parallel thereto, the stepped part 1a of the material is pressed with the end part of the forming face 2a, and the peripheral wall 1c is drawn outside in a slender form. Next, the preliminary forming 5 is similarly supported by rotary molds for final forming 6, 7 and rotated to press against a final forming roller 8. Thus closely contacting the grooved part 5d and drawing part 5e to the forming faces 8a, 8b, respectively, V-grooved square hollow double wall is formed.
