摘要： 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.

摘要： A flow-forming method and apparatus, in which a blank is placed on a rolling mandrel of a flow-forming machine, the blank is rotated relative to at least one flow-forming roll, the at least one flow-forming roll is infed radially and/or axially relative to the blank, and the blank is axially lengthened by the flow-forming roll and flow-formed to a workpiece. The method and apparatus compensate dimensional variations of the blank by working at least one compensating area into the workpiece, determining, before and/or during flow-forming, geometrical data of the blank and/or workpiece with a measuring device, obtaining a desired final geometry of the workpiece by individually calculating the geometrical parameters of the at least one compensating area as a function of the geometrical data determined, and controlling the infeed of the flow-forming roll in accordance with the calculated geometrical parameters of the compensating area, so that a workpiece with the desired final geometry can be formed independently of dimensional variations of the blank.
