Abstract
PURPOSE: To obtain the wheel which is ideal in terms of strength and accuracy by coupling the disc to be integrated with rims to a hub mounting flat plate and circular truncated-cone-form members and using said circular truncated-cone-form members made by the specific process.
CONSTITUTION: To produce the circular truncated-cone-form members, a cylindrical blank 10 is depressed and curved to the inside diameter direction along the circumferential direction at its central part by a roll-forming device. The portions extended upward from the central axial line G-G of the cylindrical stock 10 become thinner as they go further from the axial center and the portions formed in the axial center direction become thicker as they go closer to the axial center. This is bisected along the cutting line (e) to obtain circular truncated-cone-form members 10a, 10b. A circular stock 10c is press-formed in the arrow direction. The portions extended outward become thinner as they go furhter from the axial center and the portions formed at the axial center become thicker as they go closer to the axial center, whereby a truncated-cone-form part 10d is obtained. These truncated-cone- form members and hub mounting flat flate are coupled to constitute the disc.
