Production of a one-part, cylindrical wheel rim mold having an annular section with a starting material thickness and an annular section with an end material thickness

摘要

Production from a starting cylinder (10) of a one-part, cylindrical wheel rim mold having at least one first annular section with a starting material thickness (a) and at least one second annular section with an end material thickness (b, c) different to the starting material thickness comprises partially heating the starting cylinder in the region of an annular zone and heat-molding the heated annular zone by introducing an axial force (Z). An independent claim is also included for a wheel rim for vehicle wheels. Preferred Features: The starting cylinder is made of a strip material having constant starting material thickness.
