Description

Изготавливают деталь «вал-бочка из жаропрочного сплава на хром-никелевой основе ЭЙ 437БУ. Деталь представл ет собой стакан с двум  торцовыми фланцами высотой 820 мм, внутренний диаметр стакана - 320 мм, наружный - 400 мм, наружный диаметр верхнего фланца - 430 мм, нижнего фланца - 456 мм.Make the item "shaft-barrel of heat-resistant alloy on a chromium-nickel base YO 437BU. The part is a cup with two end flanges with a height of 820 mm, an inside diameter of the glass — 320 mm, an outer diameter — 400 mm, an outer diameter of the upper flange — 430 mm, and a lower flange — 456 mm.

В качестве исходной заготовки используют штангу диаметром 300 мм, длиной 690 мм и весом 400 кг. Заготовку подвергают нагрепу до ИбОС и производ т высадку нижнего фланца до диаметра 440 мм, что составл ет 0,97 диаметра нижнего фланца детали.As the source of the workpiece using a rod with a diameter of 300 mm, a length of 690 mm and a weight of 400 kg. The billet is subjected to heating up to IBOS and the lower flange is set up to a diameter of 440 mm, which is 0.97 of the diameter of the lower flange of the part.

Затем заготовку с высаженным фланцем подогревают до 1140°С, запрессовывают в обойму из стали 3, подогретую до 400°С, т. е. до температуры на 350°С ниже нижнего предела ковочных температур материала обоймы , и высаживают верхний фланец.Then, the billet with an upset flange is heated to 1140 ° C, pressed into a steel 3 case, heated to 400 ° C, i.e., to a temperature 350 ° C below the lower limit of the forging temperature of the material of the cage, and the upper flange is planted.

Обойму с заштампованной заготовкой нагревают до 1100°С и производ т образование полости стакана обратным выдавливанием.The clip with the stamped billet is heated to 1100 ° C and the formation of the cavity of the glass is carried out by reverse extrusion.

Способ обеспеЧИвает высокое качество изделий из труднодеформированных сплавов, поскольку исключаетс  возможность искажени  формы и разрушение заготовки в процессе деформнровани . Способ не требует применени  разъемных матриц, что ведет к упрощению используемого оборудовани  и инструмента .The method ensures high quality of products from hard-wrought alloys, since the possibility of shape distortion and destruction of the workpiece during the deformation process is eliminated. The method does not require the use of detachable matrices, which leads to a simplification of the equipment and tools used.
