Description
Штамповка стальных дисков турбин в закрытых штампах известна и примен етс в промышленности, однако серьезным недостатком этого способа вл етс разрушение заготовкн нз жаропрочных сортов стали в процессе штамповки дисков.The stamping of steel turbine disks in closed dies is known and used in industry; however, a serious disadvantage of this method is the destruction of workpieces in heat-resistant steel grades during the process of stamping disks.
В описываемом способе указанный недостаток устранен тем, что перед Н1тамновкой в заготовке прон иваетс нентральное отверстие. Заготовка лгожет быть выполнена в форме по.того слитка или Kpyivioii поковки. Закрыты штамп состоит из приемника и пуа 1сона. При И1тамповке дисков нз особо хрупких сплавов с целью предупреждени разруптени заготовки в последнюю перед штамповко вставл етс втулка из пластичного материала.In the described method, this disadvantage is eliminated by the fact that a non-central aperture passes in front of the H1 alloy in the workpiece. The workpiece can be made in the form of a ingot or Kpyivioii forgings. The closed stamp consists of a receiver and a 1son switch. When I1 stamping the disks of especially brittle alloys, in order to prevent the workpiece from being disintegrated, a sleeve of plastic material is inserted into the last one before the stamping.
Технологически процесс гитамповки крупногабаритных дисков дл паровых и газовых турбгтн, а также дл реактивных двигателе - в закрытом штампе состоит в следующем .Technologically, the process of wiring for large-sized disks for steam and gas turbgs, as well as for jet engines - in the closed die is as follows.
Штамповка дисков осуигествл етс за один ход пресса при помоши закрытого приемника и пуансона. В качестве исходной за.готовки нсно .1ьзуетс no.ibiii слиток. При изготовле И1н дисков ста.тей, обладаюищх достаточным запасом пластнч юсти, в качестве 1 сходно1 1 заготовки исиользустс CH IOHIHOII с,1ито ч. этом приме етс следуюи1а технологи :The punching of discs is realized in one stroke of the press with the help of a closed receiver and a punch. As an initial preparation, it is clear that .1 is no.ibiii ingot. When fabricating I1n disks, articles that possess a sufficient supply of plastic plastics, as 1 similarly 1 billet and use CH IOHIHOII, 1 of which is used in the following technology:
а)отрубка прибыли и поддона н разрубка слитка на заготовки;a) cutting off profits and pallet n cutting the ingot into blanks;
б)осадка заготовки;b) draft of the workpiece;
в)П юип1вка отверсти ;c) Hole hole;
г)И та шовка в закрытом штампе .d) And that one is in a closed stamp.
иlтa иoвкe aтepиaл перемеи .аетс в радиальном наирав.теиии от периферии к цеитру. Если штамповка Ир01 ЗВОДИТСЯ ИЗ ОСОбо хруиких снлавов, то в центральное отверстие диска вставл етс втулка нз тластичного aтepиaлa, вслелств е чего создаю цнм с на внутренней поверхности дополп тельными сжимаю Ц ми напр жени и можно деформ ровать хрупкие сплавы без их разрун1е н . При этом снижаетс тpyдoe кocть изготовлени дисков. and the virus of the variable. in radial narav.teii from the periphery to the zeitra. If the stamping of IR01 IS BECOMING FROM THE SPECIAL CHRONIC LEVELS, then a bushing for the plastic material is inserted into the central hole of the disk, so that I create cnm with an compressive compressive stress on the inner surface and it is possible to deform brittle alloys without decomposing them. This reduces the hardness of disc production.
