PROCEDE DE FABRICATION DE ROUES, SANS ENLEVEMENT DE COPEAUX, NOTAMMENT DE ROUES DE VEHICULES AUTOMOBILES

摘要

Wheels, particularly for automotive vehicles, are made by first forming a disk-shaped blank, forging the same into a semi-finished wheel having a hub and a wheel disk surrounding the hub and having a peripheral rim provided with a cylindrical circumferential edge face, and then mounting the semi-finished wheel in a machine. The edge face is thereupon engaged with at least one pressure roller and split under application of pressure in direction inwardly of the edge face and towards the hub to obtain two unfinished flanges. The unfinished flanges are rollingly deformed in opposite directions axially of the hub and to the desired configuration to thereby obtain two finished wheel flanges.
