Abstract: An apparatus and a method for producing a one-part vehicle wheel are provided, in which a substantially disk-shaped, undercut-free preform is cast. Immediately after casting the preform is conveyed to a flow-forming machine, whilst maintaining a residual heat and is fixed therein. The circumferential area of the fixed preform 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.

Abstract: The invention relates to a method and a flow-forming machine for inserting a groove in a cylindrical, thin workpiece. The workpiece is rotated relative to at least one spinning roller. The spinning roller is provided with a profile corresponding to the groove to be shaped. The spinning roller is radially infed to the workpiece and the groove is shaped. A particularly precise forming of the groove is brought about in that simultaneously with the radial infeeding of the spinning roller and the shaping of the groove, the workpiece is axially upset by means of at least one punch.

Abstract: A gear part and method is provided for forming a gear part, in which a circular blank-like workpiece is fixed in a flow-forming machine in a radially inner area, the circular blank-like workpiece is rotated, at least one roller is infed and the roller is substantially radially moved inwardly, in which during the radial moving in workplace material flows radially, so that the workplace wall thickness is reduced in this area, in a central area of the workplace a boss is formed and during radial moving in the roller is increasingly axially infed. The method also relates to forming a gear part in which the circular blank edge is thickened by at least one forming roller, the shaping of the circular blank edge taking place through the contour of gripping jaws and/or the forming roller and the cross-section of the circular blank edge in formed in an approximately rectangular manner.
