    Abstract: A method of manufacturing vehicle wheels from a disc blank, in which the wheel has rim portions of uniform thickness and different lengths. The wheel is made by spin forging the edge portion of the disc to form an angled portion, splitting the disc into two split portions one of which has the angled portion joined at its end and forming the split portions into a desired rim configuration. A groove may be formed on the periphery of the angled portion to precisely fix the location of the split.

    Abstract: A process for making an aluminum vehicle wheel. The process includes casting the body of the wheel from aluminum. The drop center of the wheel is shot peened to seal air-transfer holes and also to increase the fatigue strength thereof. Next, both the drop center and the face of the wheel are shot peened with a finer shot to thereby reduce the surface roughness of the drop center and the face.

    Abstract: A process and apparatus for making a metal annular member of precise tolerances. The workpiece is formed by welding sheet metal into a tube. The workpiece is presized by expanding it and plastically stretching it into a precise predetermined annular configuration adapted to closely fit a post element having a pair of spaced annular liquid seals mounted thereon. The post element and workpiece are positioned within an annular lower outer die. A cup-shaped upper outer die is placed over the lower die and is used to compress the post element to squeeze the liquid seals to expand them. Forming of the workpiece is accomplished by pumping liquid into the post element between the liquid seals forcing the workpiece to expand against the outer dies and the sheet metal at the end portions of the workpiece to feed into the part being formed from between the outer dies and the post element.

    Abstract: A polished steel wheel center with hub, outwardspreading spokes, and rim; the metal having substantially the same thickness throughout; the ratio of the center diameter to the hub height being substantially 5; the center having slots intermediate the outer areas of the spokes; the center having deeply recessed lug pockets intermediate the spokes; the terminus of the rim, the bottom of the lug recesses, and the bottom of the hub being in substantially the same plane; the slots being in a plane intermediate top and bottom of the hub. Method of forming an automobile wheel center comprising as a first step, prepolishing the stock; forming a deep draw in the blank; forming alternate spoke and lug pocket areas, the lug pocket areas being approximately in the same plane as the periphery of the blank; further forming the lug pockets to depress same below the plane of the peripheral plane of the blank while simultaneously reducing the height of the hub area; in a subsequent forming step, still further depressing the lug pockets below the plane of the periphery, and still further reducing the height of the hub area; forming lug bosses and stamping out the hub center; and piercing peripheral slots and lug holes.
