| description | FIELD: process engineering. ^ SUBSTANCE: invention relates to metal forming, particularly, to method of producing hollow fane vane from titanium alloy. To make aerodynamic surface on billet, its sections to be jointed to filler billet are made in the form of ledges with flat cross section, and sections not to be jointed to filler billet are made as slots. Note here that, at least, one part of slots surface opposite the ledges in package assembled for diffusion welding is made flat in cross section. Coat to resist jointing is applied on surface of billet sections not to be jointed. Filler and shell billets are assembled into package and welded by diffusion. Stiffness ribs are produced by super plastic forming. After diffusion welding, aerodynamic profile is made by deforming said billets. Vane pressure surface and back are formed. Vane root is twisted. ^ EFFECT: higher quality of vane, reduced labour input. ^ 2 cl, 10 dwg, 1 ex
Изобретение относится к области обработки металлов давлением, более конкретно к способам изготовления полой вентиляторной лопатки из титанового сплава. До придания аэродинамического профиля на поверхности заготовок обшивок участки, подлежащие соединению с заготовкой наполнителя, оформляют в виде выступов с плоской в поперечном сечении поверхностью, и соответственно участки, не подлежащие соединению с заготовкой наполнителя, оформляют в виде пазов. При этом, по крайней мере, часть поверхности пазов, противолежащую в собранном для диффузионной сварки пакете выступам, выполняют в поперечном сечении плоской. Осуществляют нанесение на поверхность участков заготовок, не подлежащих соединению, покрытия, препятствующего соединению, сборку заготовок обшивок и наполнителя в пакет, диффузионную сварку заготовок обшивок и наполнителя, формирование ребер жесткости сверхпластической формовкой. После диффузионной сварки заготовкам обшивок и наполнителя придают аэродинамический профиль путем приложения к ним деформирующей нагрузки, формируют корыто и спинку лопатки и осуществляют закрутку пера лопатки. Повышается качество лопатки при упрощении и снижении трудоемкости технологического процесса. 1 з.п. ф-лы, 10 ил. |
