Description
д т профилиразание пера и окончательную вальцовку.d t profiles the formation of the pen and the final rolling.
П р ,и м е р. В качестве материала в одном варианте берут сталь ЭП517, а в .другом варианте - титансвый сплаз ВТЗ-1. Полосы фасонного ромбовидного сечени подвергают натреву в расплаве солей BaiCl2 в течение 4 мин, а затем периодическому прокату и разделению на инди.Бидуальнь5е заготовки. После чего осуществл ют регламентированный наг .рев заготовок в воздуииной среде с лредзарительным натрезом щри 600° С i3 течение 8 мин и око.нчательном нагреве при 900° С в течение 4 мин, а затем провод т профилирование пера и формоБку замка.PRI and meer. In the quality of the material in one embodiment, steel EP517 is taken, and in the other version - titanium splaze VTZ-1. Strips of shaped diamond cross-section are subjected to natura in the molten salt of BaiCl2 for 4 min, and then periodically rolled and separated into indie. After that, a regulated heating of the blanks is carried out in air with a conventional cut of 600 ° C i3 for 8 minutes and extensive heating at 900 ° C for 4 minutes, and then the profiling of the pen and the lock are carried out.
Применение способа позвол ет получать после периодического проката кромки затотовок лопаток величиной 1 мм, тогда как при известнам .слоообе .получают кромку пера не менее ,2,5 мм и производ т дальнейшую обработку слесарной ручной доводкой.The application of the method makes it possible to obtain, after periodic rolling, the edge of the grinding of blades of 1 mm, whereas with a known layer, a feather edge is not less than 2.5 mm and is further processed by fitting.
Д ННый спосОб знагчителыно удешевл ет процесс, так «ак ретламентирован-ный натрев исключает нагрев в инертной среде (аргоне), что делает способ менее трудоемким.DIMENTAL METHOD makes the process very expensive, since the adopted batch eliminates heating in an inert medium (argon), which makes the method less labor intensive.
Применение фасонного ромбовидного сечени полосы позвол ет уменьшить удельные да1вле1ни, три лериодичеоком прокате на 30%, что приводит к меньшему износу рабочих частей Секторов вальцовочной оснастки.The use of a shaped diamond cross-section of the strip allows reducing the specific durations of three long-period rolled steel by 30%, which leads to less wear on the working parts of the rolling tool sectors.
Данный способ по сравнению с известными способами обеспечивает следук ш,ие преимушества: получение кромок заготовки .пера лопатки; снижение удельных давлений На р-абОчие части секторов вальцовочной оснастки; значительное удешевление процесса в целом.This method, in comparison with the known methods, provides the following advantages: the preparation of the edges of the workpiece blade; reduction of specific pressure On the p-abOchie part of the sectors milling equipment; a significant reduction in the cost of the whole process.
