METHOD AND DEVICE FOR PRODUCING A ONE-PIECE VEHICLE 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.
