ABSTRACT:
An improved method is disclosed for producing a wheel rim for use in a vehicle wheel. The method includes the steps of: (a) providing a flat sheet of material; (b) forming the flat sheet into a hoop having a first predetermined axial length; (c) expanding the hoop to a predetermined inner hoop diameter; (d) flow spinning the hoop to produce a wheel rim preform having a second predetermined axial length greater than the first predetermined axial length, the wheel rim preform including opposed axial ends and a thinned axially extending intermediate portion located between the axial ends; (e) subsequent to step (d), flaring at least one axial end of the wheel rim preform; and (f) subsequent to step (e), subjecting the wheel rim preform to a series of roll forming operations to produce a finished wheel rim having at least one tire bead seat retaining flange, at least one tire bead seat surface, and a generally axially extending well.
