Abstract:
This invention relates to a unitary steel wheel as well as an apparatus and method for producing a unitary steel wheel. The unitary wheel comprises rim and disc components. In one embodiment, the unitary wheel further comprises approximately a 50 taper bead-seat for flat or semi-drop cantar rims, produced from a generally circular steel blank. The blank preferably has a cantar hole of predetermined size. In a first step, the blank is initially placed in a spinning machina to form disk and rim portions of a predetermined profila and shape. The preform is further spun and flow formed in the spinning machine, to form a gutter, well, bead-Seat, and/or fixed flange. The preform is then forward and reverse spun to form the final profila and shape of the gutter, wall, bead-seat, and/or fixed flange.
