Abstract:
1. A wheel rim roll forming apparatus comprising: an inner roll assembly adapted to support a flared wheel rim preform thereon, the inner member including an outer surface having a predetermined profile and defining a centerline of the apparatus; an upper roll member supported relative to the inner roll assembly, the upper roll member having an inner surface having a predetermined profile adapted to engage the flared wheel rim preform to produce a partially formed wheel rim having a desired profile; a pair of axially adjustable guide ring assemblies operatively supported by the inner roll assembly and operatively disposed adjacent an associated end of the flared wheel rim preform, wherein each of the guide ring assemblies includes a generally cylindrical guide ring having a plurality of spaced apart bores formed through an outer peripheral flanged portion thereof and a releasable actuator adapted to be operatively disposed in a selected one of the plurality of bores; and a lateral ring secured to each one of the guide ring assemblies, the lateral rings adapted to engage flanged ends of the wheel rim preform; wherein the guide ring assemblies are axially adjustable by releasing the actuators from engagement in a selected one of the plurality of bores and moving the guide rings assemblies by one of a rotational or axial movement to a desired position.
