Description
Изобретение относитс к обработке металлов давлением, а именно к способам изготовлени изделий из алюминиевых сплавов .The invention relates to the processing of metals by pressure, in particular to methods for the manufacture of products from aluminum alloys.
Известен способ изготовлени изделий из алюминиевых сплавов, включающий предварительное деформирование заготовки при температуре 200--300°С и последующую гор чую штамповку {. A known method of manufacturing products from aluminum alloys, including the preliminary deformation of the workpiece at a temperature of 200--300 ° C and subsequent hot stamping.
Однако необходимость приложени значительных усилий на последнем переходе штамповки снижает экономичность процесса изготовлени изделий.However, the need to make significant efforts at the last transfer of stamping reduces the efficiency of the process of manufacturing products.
Дл повышени экономичности процесса предварительное деформирование заготовки осуществл ют изотермической объемной штамповкой со скоростью деформировани I -10 мм/сек.To increase the efficiency of the process, the preliminary deformation of the workpiece is carried out by isothermal forging with a deformation rate of I-10 mm / s.
Скоростной интервал деформировани обуславливаетс оптимальными услови ми в отношении формировани мелкозернистой сверхпластичной структуры, необходимой дл последующей штамповки, и выбираетс экспериментально.The speed warping interval is determined by the optimal conditions for the formation of a fine-grained superplastic structure necessary for subsequent stamping, and is chosen experimentally.
Пример конкретной реализации способа.An example of a specific implementation of the method.
Провод т штамповку панели с лучевыми ребрами размером 8(Ю х 4(Ю 16 мм изIt conducts the stamping of a panel with radial fins of size 8 (U x 4 (U 16 mm from
заготовки в виде плиты толщиной 40 мм. Материал заготовки - алюминиевый сплав Д20.blanks in the form of a plate 40 mm thick. Preparation material - aluminum alloy D20.
Вначале провод т предварительное деформирование заготовки в заготовительном штампе в изотермических услови х при температуре ЗбО°С со скоростью деформировани 7 мм/сек при степени деформации 20%.Initially, pre-deformation of the workpiece is carried out in a blank die under isothermal conditions at a temperature of 0.20 ° C at a deformation rate of 7 mm / s with a degree of deformation of 20%.
Затем заготовку подогревают до температуры 480°С и осуществл ют штамповку в изотермических услови х со скоростью деформировани 2 мм/сек.The billet is then heated to a temperature of 480 ° C and stamped under isothermal conditions at a deformation rate of 2 mm / s.
При этом за счет соблюдени указанных условий удельное усилие на окончательной штамповке составл ет 15 кг/см, что в 2- 2,5 раза ниже удельного усили по известной технологии.At the same time, due to the observance of the indicated conditions, the specific force at the final stamping is 15 kg / cm, which is 2 to 2.5 times lower than the specific force according to known technology.
Предложенный способ позвол ет осуществить качественное изготовление изделий из алюминиевых сплавов при повышенной экономичности процесса.The proposed method allows high-quality manufacturing of products from aluminum alloys with an increased process efficiency.
