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.

Изобретение относится к обработке металлов давлением, в частности к технологии изготовления цельнокатаных железнодорожных колес. Цель: разработка способа изготовления железнодорожных колес, позволяющего ограничить истечение в диск колеса центральной зоны заготовки объемом до 7500 см3 за счет образования центральной перемычки в процессе разгонки заготовки толщиной 0,17 - 0,33 от высоты осаженной заготовки, и диаметром, равным 0,9 - 1,1 диаметра отверстия ступицы. Формовку заготовки осуществляют при соотношении высоты рабочей части нижней и верхней полуоправок в пределах 0,6 - 0,8.The invention relates to the processing of metals by pressure, in particular, to the technology of manufacturing solid-rolled railway wheels. Purpose: to develop a method for manufacturing railway wheels, which makes it possible to limit the outflow into the disk of the wheel of the central zone of the workpiece with a volume of up to 7500 cm 3 due to the formation of a central bridge in the process of accelerating the workpiece with a thickness of 0.17 - 0.33 from the height of the deposited workpiece, and a diameter equal to 0, 9 - 1.1 of the diameter of the hole in the hub. The workpiece is formed at a ratio of the height of the working part of the lower and upper half-corrections in the range of 0.6 - 0.8.
