Abstract

Надається опис способу виготовлення колісних осей, зокрема для залізничних вагонів, з порожнистим тілом осі (1), яке утворює осаджені відносно потовщених опорних частин (2) шийки (3) для приймання коліс і має внутрішній діаметр шийок (3), менший відносно розширеного внутрішнього діаметра між опорними частинами (2), при цьому зовнішній профіль тіла осі (1) виконують шляхом кування. Щоб виключити з процесу виготовлення осей цикл обробки, пов'язаний зі зніманням стружки, пропонується порожнисту ковальську заготівку (8) з внутрішнім діаметром, який принаймні відповідає розширеному внутрішньому діаметру тіла осі (1), поступово кувати в осьовому напрямку, використовуючи ковальську оправку (13) з формувальною ділянкою (15) для розширеного внутрішнього діаметра тіла осі (1), перш ніж витягнути формувальну ділянку (15) для розширеного внутрішнього діаметра з одного кінця порожнистої ковальської заготівки (8), а ще не ковану частину ковальської заготівки (8) з меншим внутрішнім діаметром кувати за допомогою ковальської оправки (13) з формувальною ділянкою (14) для меншого внутрішнього діаметра ковальської заготівки (8).A description of a method for manufacturing wheel axles, in particular for railway wagons, with a hollow axle body (1), which forms deposited relative to the thick support parts (2) of the neck (3) for receiving wheels and has an inner diameter of the necks (3), smaller relative to the expanded inner diameter between the supporting parts (2), with the outer body profile of the axis (1) is performed by forging. In order to exclude from the process of manufacturing axes the machining cycle associated with chip removal, a hollow forging billet (8) with an inner diameter at least corresponding to the expanded internal diameter of the axis body (1) is gradually hammered in the axial direction using the forging (13). ) with a molding section (15) for the extended inner diameter of the axis body (1) before removing the molding portion (15) for the expanded inner diameter from one end of the hollow forging workpiece (8) and not yet forged parts forge a workpiece (8) with a smaller inner diameter forge with a forging mandrel (13) with a molding section (14) for a smaller internal diameter of the forge workpiece (8).
