Method for producing wheel disc molds on flow-forming machines, vehicle wheel with such a wheel disc mold and spinning chuck for flow-forming machines for producing corresponding wheel disc molds

摘要

The invention relates to a vehicle wheel having a wheel bowl 10, connecting flange 12, produced on a flow-forming machine by pressure rolling of a preferably metallic preform against a spinning chuck, a grooved bowl-shaped transition surface 33 provided with ventilation holes, and a bowl rim 14 for connecting the wheel bowl to a rim part. The invention also relates to the method for producing the wheel disc and to a spinning chuck for a suitable flow-forming machine. In order to improve the production of vehicle wheels with wheelsets produced by pressure rollers and thereby to allow weight reductions in the finished vehicle without additional, the production of the wheel-lengthening steps. are at the inside 16 or the outside of the ironed transition surface between adjacent ventilation holes, and / or between the ventilation holes at the edge of the bowl, and / or at the bowl edge in the axial extension of each vent hole at least one generated during spin forming zone 20 with accumulation of material and / or zone 15 Material reduction is formed.
