METHOD OF MANUFACTURE OF WROUGHT-STEEL WHEELS Russian patent published in 1997 - IPC

Abstract RU 2080200 C1

FIELD: plastic metal working, particular, hot forging and rolling of railroad wheels. SUBSTANCE: in course of rolling the outer surface of wheel rim is formed to obtain the profile of finished configuration. During rim sizing in width, the side surface from the inner side is made at angle to side surface of rim from the outer side with direction of metal flow towards rim outer surface. Machining of rim side surface from the inner side is also made at the same angle. The offered method provides for manufacture of wheels with increased diameter of rim with preservation of the mass of initial blank. EFFECT: higher efficiency. 1 dwg
