Description
Крепление тонкостенных трубок в коллекторных досках, особенно радиаторов авиационных двигателей, путем обычной развальцовки их, не достигает цели, так как трубки, имеющие толщину стенки примерно 0,12-0,15 млг, рвутс при вальцовке.The fastening of thin-walled tubes in collector boards, especially of aircraft engine radiators, does not reach the goal by means of their usual flaring, since tubes having a wall thickness of about 0.12-0.15 milligrams tear when rolling.
Предлагаемый способ укреплени тонкостенных трубок в коллекторных досках, преимущественно радиаторов авиационных двигателей, заключаетс в том, что концы трубок ввод тс в кольцевые канавки, концентрично проточенные вокруг проходных отверстий коллекторной доски. Выступы последней , образованные при протачивании канавки, затем развальцовываютс изнутри, чем и создаетс надежное и прочное крепление, плотность которого обеспечена как при давлении внутри трубки, так и вне ее.The proposed method of reinforcing thin-walled tubes in collector boards, mainly aircraft engine radiators, is that the ends of the tubes are inserted into annular grooves concentrically machined around the through-holes of the collector board. The protrusions of the latter, formed when the grooves are pierced, are then flared from the inside, which creates a reliable and durable fastening, the density of which is ensured both at the pressure inside the tube and outside it.
На чертеже фиг. 1 изображает частичный разрез коллекторной доски при применении предлагаемого способа укреплени в ней тонкостенных трубок; фиг. 2-то же с введенными в нее трубками; фиг. 3-то же с применением монтажной промежуточной доски.In FIG. 1 shows a partial section of a collector board when applying the proposed method of strengthening thin-walled tubes therein; FIG. 2 - the same with the tubes inserted into it; FIG. 3 is the same with the use of mounting intermediate boards.
В коллекторной дойке 1 (фиг. 1) с проходными отверсти ми 2 со стороны вставки тонкостенных трубок делаютс соответствующей глубины выемки 3, диаметр которых равен наружному диаметру трубки. Затем концентрично вокруг проходных отверстий 2 протачиваютс кольцевые канавки 4, образующие кольцевые выступы 5. Внутрь канавок 4 вставл ютс концы трубок 6 {фиг. 2), а выступы 5 изнутри развальцовываютс , чем и создаетс уплотнение укреплени трубок, обеспечивающее плотность его как при давлении внутри трубки, так и давлении вне ее.In the collector milking 1 (Fig. 1) with through holes 2 on the side of the insertion of thin-walled tubes, the corresponding depth of the recess 3 is made, the diameter of which is equal to the outer diameter of the tube. Then, annular grooves 4, which form annular protrusions 5, are pierced concentrically around the through holes 2. The ends of the tubes 6 are inserted inside the grooves 4 {fig. 2), and the protrusions 5 are flared from the inside, which creates a seal that strengthens the tubes, ensuring its density both at the pressure inside the tube and at the pressure outside it.
Дл удобства сборки при больщом количестве трубок может быть применена монтажна промежуточна доска 7 (фиг. 3), снабженна отверсти ми по наружному диаметру трубок 6.For convenience of assembly, with a large number of tubes, a mounting intermediate board 7 (Fig. 3) may be used, provided with openings along the outer diameter of the tubes 6.
Заготовленна описанным способом коллекторна доска 1 собираетс вместе с доской 7 при помощи установочных трубок 8 и болтов 9. Трубки 6 набираютс по одной в нижней доске 1 через отверсти доски 7. Доска 7 жестко фиксирует расположение трубок 6, и когда все трубки набраны.The collector board 1 prepared in the manner described above is assembled together with the board 7 by means of mounting tubes 8 and bolts 9. The tubes 6 are assembled one at a time in the bottom board 1 through the holes of the board 7. The board 7 rigidly fixes the location of the tubes 6 and when all the tubes are assembled.
доска 7 покрываетс верхней коллекторной доской 10, в кольцевые канавки которой вход т концы трубок 6, выступающих из отверстий доски 7.Board 7 is covered with an upper collector board 10, in the annular grooves of which the ends of the tubes 6 protruding from the openings of the board 7 enter.
Предмет изобретени .The subject matter of the invention.
Способ укреплени тонкостенных трубок в коллекторных досках, преимущественно радиаторов авиационных двигателей, отличающийс тем, что концы трубок закрепл ют в кольцевых канавках 4, протачиваемых концентрично вокруг проходных отверстий 2 доски 1, путем развальцовки изнутри кольцевых выступов 5, образованных при протачивании канавок.A method of reinforcing thin-walled tubes in collector boards, mainly aircraft engine radiators, characterized in that the ends of the tubes are fixed in annular grooves 4, which are machined concentrically around the through holes 2 of board 1, by flaring the annular projections 5 formed during the piercing of the grooves.
