Abstract: A road wheel for a track laying vehicle is made by initially roll pressing and projection drawing a planar disk of temperable steel into a blank having a cylindrical portion, a planar hub portion and an intermediate portion bridging the hub and peripheral projection. Prior to machining at least of the intermediate portions, the blank is tempered and thereby increased in size. The blank is reshaped following the tempering and prior to machining to the original blank shape and is then machined.

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.

Abstract: A method of manufacturing vehicle wheels from a disc blank, in which the wheel has rim portions of uniform thickness and different lengths. The wheel is made by spin forging the edge portion of the disc to form an angled portion, splitting the disc into two split portions one of which has the angled portion joined at its end and forming the split portions into a desired rim configuration. A groove may be formed on the periphery of the angled portion to precisely fix the location of the split.

Abstract: The invention provides a rolling forming method of wheel disc, which comprises the following steps: (1) Baiting a circular blank; (2) placing the circular blank in a cavity of a rolling explorator and adopting at least two rolling wheels symmetrically arranged along the circumferential direction of the rolling explorator to perform planar synchronous staggered rolling on the circular blank in the cavity of the rolling explorator; (3) performing trimming and sizing; and (4) stretch forming. The rolling forming method of wheel disc of this invention can precisely form various geometric sections with gradual deformation. The formed product has a uniform mass in the axial direction and the circumferential direction, and has a high dynamic balance precision. The invention can make the blank deform precisely, enhance the production efficiency, and reduce the cost, therefore the invention has good application and popularization prospect.

Abstract: A metal forming method is used for manufacturing vehicle wheels. The invention comprises manufacturing of a wheel block comprising a central part and initially formed rim; drawing of the rim by hot rolling to obtain a wheel profile that approximates a finished wheel, and a final wheel treatment process. The rolling is conducted from either side of the wheel block, which may comprise any granular microstructure. Rolling temperature-strain rate conditions correspond to the microstructure. For a coarse-grain microstructure, the rim includes a shoulder with a thickness greater than that of the finished wheel, and thickness differences transform the microstructure into a recrystallized and/or polygonized microstructure. For a fine-grain microstructure, the rim includes a shoulder or flange with a thickness close to a thickness of a finished wheel. For mixed microstructures, the rim includes a shoulder and has a thickness greater or equal to a finished wheel.

Abstract: The invention relates to a method for forming a hub disk, in which a circular blank-like workpiece is placed in a flow-forming machine and fixed with at least one overarm support, an area of the outer contour of the overarm support corresponding to an area of the inner contour of a hub to be formed, the circular blank-like workpiece is rotated, at least one roller is infed and substantially radially moved in, a material flow taking place on the workpiece, and the radial moving in of the roller is ended when the distance between an area of the outer profile of the roller and the overarm support corresponds to the desired thickness of the hub wall and during the infeeding of the roller the workpiece is initially contacted by a cutting or separating edge of the roller and the material flow along the roller and therefore the axial length of the hub is limited by the roller geometry. The invention also relates to a roller for use in forming a hub disk, the outer circumference of the roller having a cutting edge, with which it initially contacts a workpiece to be formed, and a circumferentially positioned projection spaced from the cutting edge is provided for limiting the axial material flow.

Abstract: A method of making one-piece vehicle wheels and the like includes providing a generally circular blank from sheet stock. The blank is preferably preformed with a center portion in the final shape of the disc portion of the wheel, and a peripheral portion for spin shaping the final shape of the rim portion of the wheel. The preformed blank is positioned between an outer mandrel and an inner mandrel having a fixed outboard surface, and an inboard shaping surface which conforms to the final shape of at least a portion of the rim well and the inboard bead seat and flange. An inboard section of the blank peripheral portion is spin formed against the inboard shaping surface of the inner mandrel to form the final shapes of at least a portion of the rim well and the inboard bead seat and flange. An outboard section of the blank peripheral portion is spin formed by engaging the same with a forming roller while the associated portion of the blank peripheral portion remains spaced apart from and unsupported by the fixed outboard surface of the inner mandrel to form the final shape of the outboard bead seat.
