Method and device for producing a one-piece vehicle wheel
Abstract:
An apparatus and a method for producing a one-part vehicle wheel are provided, in which a substantially disk-shaped, undercut-free pre-form is cast. Immediately after casting the pre-form is conveyed to a flow-forming machine, while maintaining a residual heat and is fixed therein. The circumferential area of the fixed pre-form is split and, by subsequent spinning and flow-forming, is constructed as an intermediate form with a rim, which already substantially has the wall thickness of the rim of the finished vehicle wheel. The intermediate form is cooled, sized, and undergoes a final end-working.
