The purpose of the invention is to increase the durability of the dies. The method can be processed mainly alloys of titanium. Stamping is carried out with the presence of lubricant on the surfaces of the stamp or blank of a soot layer of a high degree of dispersion, such as DG-100. At the same time, the value of a soot layer on the workpiece is determined by the dependence a K (Zcon / Value), where K 0.15-0.7 mm is the thickness of the soot layer on the product; Zkon - the surface area of the manufactured part; Value - the surface area of the workpiece. In the process of spontaneous combustion of soot can be prevented by blowing an inert gas, such as argon, nitrogen, heated to the temperature of operation of the stamp. sl C
Description
Изобретение относитс к обработке металлов давлением, а именно к способам штамповки изделий в изотермических услови х или в услови х сверхпластичности, и может быть использовано при штамповке титановых, циркониевых, ниобиевых и других им подобных металлов в штампах из жаропрочных сплавов на никелевой или кобальтовой основе.The invention relates to the processing of metals by pressure, in particular to methods of forming articles under isothermal conditions or under superplasticity conditions, and can be used for stamping titanium, zirconium, niobium and other similar metals in dies of heat-resistant alloys on nickel or cobalt.
Цель изобретени - повышение стойкости штампов.The purpose of the invention is to increase the durability of the dies.
Способ штамповки заключаетс в следующем .The stamping method is as follows.
Заготовку или штамп покрывают слоем сажи высокой степени дисперсности, например , марки ДГ-100. При этом величину наносимого сло определ ют из выражени The blank or stamp is covered with a layer of soot of a high degree of dispersion, for example, DG-100 grade. The value of the applied layer is determined from the expression
а Кand K
ЗначValue
где К 0,15...0,7 мм - толщина сло сажи, оставшегос на детали после деформировани ;where K 0.15 ... 0.7 mm is the thickness of the soot layer remaining on the part after deformation;
SKOH - площадь поверхности заготовки;SKOH - the surface area of the workpiece;
Знач - площадь поверхности детали.Value is the surface area of the part.
Сажу на поверхность деталей можно наносить любым известным способом, например обмазкой суспензией сажи в воде или обсыпанием.Soot on the surface of the parts can be applied in any known manner, for example by coating with a suspension of soot in water or sprinkling.
Далее, заготовку нагревают и помещают в нагретый до температуры деформаций штамп, например до 1000°С, и деформируют ее в изотермических услови х со скорост ми , например, 0,5...50 мм/мин. После деформировани отштампованное изделие извлекали из штампа.Further, the billet is heated and placed in a stamp heated to the deformation temperature, for example, up to 1000 ° C, and deformed under isothermal conditions with speeds, for example, 0.5 ... 50 mm / min. After deformation, the stamped product was removed from the stamp.

Пример. Деформировали малогабаритную лопатку турбины из сплава ВТ9 в штампе, выполненном из никелевого жаропрочного сплава ЖС6У, Заготовка диаметром 11 мм и длиио 24 мм имела площадь поверхности 1848мм г. Готова лопатка с замком 4мм, средней толщиной пера 2 мм, высотой пера 49 мм и длиной 20 мм имела площадь поверхности 2280 мм. На основе этого толщина сло сажи на заготов- ке составл ла 0,5 мм. При этом использова- ли сажу ДГ-100, которую наносили окунанием заготовки в водную суспензию сметанной консистенции. Затем покрытую сажей заготовку устанавливали в штамп, выдерживали 5 мин дл выравнивани температур и деформировали со скоростью 20 мм/мин до получени готовой детали. После штамповки 100 деталей износ рабочей поверхности штампа равномерный без ка- верн.Example. The small-sized turbine blade from VT9 alloy in a stamp made of nickel heat-resistant alloy ZhS6U was deformed. The blank with a diameter of 11 mm and a length of 24 mm had a surface area of 1848 mm. The blade with a lock of 4 mm, an average pen thickness of 2 mm, a feather height of 49 mm and a length of 20 mm was prepared. mm had a surface area of 2280 mm. Based on this, the thickness of the soot layer on the workpiece was 0.5 mm. In this case, DG-100 carbon black was used, which was applied by dipping the billet in an aqueous suspension of sour cream consistency. Then, the soot-coated workpiece was placed in the die, held for 5 minutes to equalize the temperatures, and deformed at a speed of 20 mm / min to obtain the finished part. After punching 100 parts, the wear of the working surface of the stamp is uniform without caverns.
Способ штамповки кроме повышени стойкости инструмента может снизить окислительный износ за счет частичного окислени сажи, а также может способствовать The stamping method, in addition to improving tool life, can reduce oxidative wear by partially oxidizing soot, and can also contribute to
снижению затрат на материалы инструмента за счет использовани менее дорогих и менее дефицитных материалов.reducing tool material costs by using less expensive and less scarce materials.
