Abstract
FIELD: plastic metal working. SUBSTANCE: proposed process of manufacture of railway wheels makes it possible to limit effusion of central zone of blank having volume up to 7500 cu.cm into disc of wheel due to formation of central strap in process of spread of blank having thickness 0.17-0.33 of height of upset blank and diameter equal to 0.9-1.1 diameter of hole of hub. Forming of blank is performed with relation of height of working part of lower and upper semi-mandrels within 0.6-0.8. EFFECT: enhanced quality of railway wheels.
