摘要： 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.

摘要： The invention relates to a device and method for producing a one-piece vehicle wheel in which a substantially discoid, undercut-free blank is cast. Immediately after casting, the blank is transported to a pressure cylinder machine while maintaining residual warmth, and clamped therein. The clamped blank is split in the peripheral area and then configured by compressing and pressure-rolling to give an intermediate form with a wheel rim. The thickness of the wheel rim walls on the whole already corresponds to that of the completed vehicle wheel. The intermediate form is cooled and calibrated before undergoing final processing.

摘要： This invention relates to a unitary steel wheel as well as the apparatus and method of producing a unitary steel wheel. The unitary wheel comprises wheel rim and disc portions. In one embodiment, the unitary wheel of this invention further comprise a one-piece wheel of 5° and 15° dorp center rims, providing a generally circular steel blank from a sheet stock of pre-determined substantially uniform thickness. The bank preferably has a center hole having a predetermined size. The blank is performed in a spinning machine to a predetermined profile and shape. The perform is further spun and flow formed in a spinning machine, the perform being positioned between an outer roll and inner mandrel and held against a clamping plate. The inner mandrel comprises an outboard surface, which conforms to the predetermined inner diameter of the rim. The perform is further processed in the spinning machine to form a final shape and profile of the rim portion comprising a well, inner and outer flange portions, and inner and outer bead-seat portions.

摘要： The starting material in a thixotropic forming process for the manufacture of road wheels, fitted ultimately with pneumatic tyres, is an ingot (1) of rheocast metal alloy preheated to the semisolid state: the ingot is injected into a closed die (5) affording a cavity (7) in the shape of the wheel and equipped with independent thermoregulating circuits (6), routed and controlled in such a way as to maintain the wider passages (A) of the cavity at a temperature lower than that of the narrower passages (B); to ensure the die fills properly, the ingot (1) is injected at a variable and controlled velocity, correlated both to the rate at which the alloy spreads through the cavity (7) and to the geometry of the cavity itself, whereupon a pressure much higher than the injection force is applied to the solid-semisolid interface within the alloy, and sustained until full solidification is achieved.
