Abstract: An improved method for fabricating a vehicle wheel from a one-piece sheet metal blank involves a nine station transfer die. In a first station, a sheet metal blank is drawn into a dish-shaped wall, a cylindrical outside wall, a first contour, and a first side wall. In the second station, the dish-shaped wall is reverse drawn to form a hub and an inside wall, and a valve hole is punched into the first contour. In the third station, the hub is flattened to be substantially perpendicular to an axial centerline of the partially fabricated wheel, and an outer peripheral edge of the first side wall is trimmed. In the fourth station, the inside wall is laterally formed so as to be in contact with the outside wall, and an outer peripheral edge of the first side wall is wiped over to form a flange. In the fifth station, a second contour is laterally formed. In the sixth station, a first offset and inner and outer hub-stiffening embosses are drawn into the hub. In the seventh station, a second offset is drawn in the hub, and a second side wall is laterally formed to complete a tire engaging rim. In the eighth station a center aperture and a plurality of wheel mounting holes are punched in the hub. Finally, in the ninth station, the center aperture and the wheel mounting holes are extruded, and a plurality of rim-stiffening embosses are laterally formed in the rim.

Abstract: A wheel made by extruding a wheel rim form from a light metal alloy, the rim having a first tire-retaining flange; cutting the rim form to a length longer than the desired wheel circumference; joining the ends of the rim form to make a rim hoop; circumpressing the rim hoop to the desired circumference; providing a center from a light metal; and, joining the rim hoop and the wheel center along the second side of the rim to form the wheel. A second tire-retaining flange is also provided, and may be fabricated either as an integral portion of the center that is joined to the rim hoop, or as an integral portion of the rim hoop for joining to the center.

Abstract: A method and apparatus for forming wheel rims using a wheel rim blank having a well center region with a diameter equal to the diameter of the well center of the finished wheel rim. Two female die halves form a cavity to confine the wheel rim blank and two male dies cooperate with the female die halves to flare the bead seat regions of the wheel rim blank. The bead seat regions of the wheel rim blank are subsequently contoured to final dimensions between two additional female die halves by two additional male dies.
