Description

Предметом изобретени   вл ете  способ изготовлени  стальной пустоте .той лонастн воздушного вннта нз Т-образной заготовки с переменным вдоль длины сечением.The subject of the invention is a method for manufacturing a steel void. This is a lonest air inlet of a n-shaped T-shaped workpiece with a variable section along the length.

Известен способ изготовлени  из Т-образного проката лонжеронов лопасти воздушного випта с последующей припайкой к ним обшивкп.A known method of making the spars of an air-borne blade spar from the T-bar, followed by soldering to them of the sheathing.

Описываемый ниже способ отличаетс  от известного тем, что из Т-образного проката штампуетс  не .юи/керон, а вс  .топасть бечлонжеронного типа, причем ее перо не нуждаетс  в последуюш,ей механической обработке, что способствует упрощению конструкпии и производства лопасти.The method described below differs from the well-known in that the T-bar is not stamped with U.I./Keron, but instead is stamped, and its feather does not need to be machined, which simplifies the design and manufacture of the blade.

Н  фиг. 1 и 2 лопасть показана в различных стади х ее изготовлени .H FIG. 1 and 2 blades are shown in various stages of their manufacture.

Заготовкой лопасти служит Т-образный прокат /, имеющий по дли:ге переменное сечение.The blank of the blade is a T-shaped bar /, which has a variable cross-section along its length.

Первый этан обработкн заключаетс  в разметке и обрезке заготовки , после чего заготовка поступает на гидропресс дл  штамповки, причем средн   полка заготовки образует переднюю кромку 2, а концы - нижнюю 3 и верхнюю 4 поверхности.The first ethane is processed in the marking and cutting of the workpiece, after which the workpiece enters the hydraulic press for stamping, with the middle shelf of the workpiece forming the front edge 2 and the ends - the bottom 3 and the top 4 surfaces.

Второй этап состопт из следуюидих операций: рслпковой электросварки задней кромки, атомно-водородной сварки комлевой части, сн ти  сварочных напр жений в печи, высадки задней кромкп, подгонки кромок но шаблонам и фрезерованию передней под кармап дл  антнобледенительиого нагревательного элемента.The second stage consists of the following operations: rear edge electric welding, atomic-hydrogen welding of the butt part, relieving welding stresses in the furnace, landing the rear edge, adjusting the edges of the templates and milling the front part of the anti-icer heating element.

TpeTHit этап состоит из термообработки с одновременной закруткой лонасти в штампе и окончательной ее штамповки.TpeTHit stage consists of heat treatment with simultaneous spinning of lonasti in the stamp and its final stamping.

П з е д м е т изобретени The invention

Способ изготовлеин  стальной пустотелой лопасти воздушного винта безлонжеронного типа, отлпч а 0 ш и и с   тем, что, с целью упрощени  конструкцин и производства , в качестве исходиой заготовки примен ют Т-образный прокат переменного по длине сечени , из средней полки которого образуют переднюю кромку лопасти, а две других полки загибают в штампе, образу  нижнюю и верхнюю повстхиости лопасти.A method for manufacturing a steel hollow blade propeller of a sparless type, excellent and so that, in order to simplify construction and production, T-shaped rolling of variable length section is used as an outgoing billet, from the middle shelf of which form the leading edge the blades, and the other two shelves are folded in the stamp, forming the lower and upper portions of the blade.
