Предлагаемый способ касаетс переработки армированных материалов путем намотки .The proposed method relates to the processing of reinforced materials by winding.
Известен способ изготовлени полых изделий , заключающийс в одновременной намотке на оправку уточных и основных нитей и нанесени на них св зующего. Однако таким способом можно получить только пилиндрические издели .A known method of making hollow articles involves the simultaneous winding of weft and base yarns on a mandrel and the application of a binder onto them. However, this way you can only get pilinstic products.
Целью предлагаемого способа вл етс получение изделий с криволинейным профилем . Это достигаетс тем, что уточные нити свободно укладывают на основные, закрепл только те, что наматываютс в точках изменени кривизны образующей оправки, а нанесение св зующего осушес вл ют после придани уточным нит м кривизны образующей оправки.The aim of the proposed method is to obtain products with a curvilinear profile. This is achieved by the fact that the weft yarns are loosely laid on the main ones, which are fastened only to those that are wound up at the points of change in the curvature of the forming mandrel, and the application of the binder is dried after the weaving yarns have the curvature of the forming mandrel.
На чертеже изображена технологическа схема процесса.The drawing shows a process flow diagram.
Способ осуществл ют следующим образом .The method is carried out as follows.
С установленных на щпул рнике 1 боби 2 сматывают нити основы 3 и закрепл ют их на оправке 4, Нити утка 5 сматываютFrom the mounted on shnipul rnike 1 bobi 2 wind the warp threads 3 and fix them on the mandrel 4, the weft threads 5 are wound
с бобины 6 и укладывают свободно на основные нити 3 нитеукладчиком 7 аналогично прокладке утка на бесчелночных ткапкпх станках.from the reel 6 and laid freely on the main thread 3 threading 7 similar to laying a duck on shuttleless machines.
В заданных точках, определ емых конфигурацией издели (форма 8 образующей оправки), уточные нити 5 вход т в зев основных нитей 3, образу переплетени . Количество уточных нитей 5 и плотность их укладки также определ етс расчетом из условий эксплуатации издели . Нити основы 3, наматыва сь с посто нным ;iaт жением на оправку 4, перемещаютс с различными линейными скорост ми, заг- с щими от радиуса оправки 4. Вследствие этого скорост;ь перемещени нити 5 по длине различна, и она в процессе перехвщени принимает форму образующей 8 оправки 4.At specified points determined by the configuration of the product (shape 8 forming the mandrel), the weft yarns 5 enter the shed of the main yarns 3 to form an interlacing. The number of weft threads 5 and the density of their laying is also determined by calculation from the operating conditions of the product. The warp threads 3, being wound with a constant; by pressing on the mandrel 4, move at different linear velocities that are sublimated by the radius of the mandrel 4. As a result of this speed, the strand 5 moves along the length is different, and in the process of interleaving it receives form forming 8 mandrels 4.
Полученное таким образом полотно поступает в пропиточное устройство 9, где на него наноситс св зующее, и формируетс изделие на оправке 4.The web thus obtained enters the impregnating device 9, where a binder is applied to it, and a product is formed on the mandrel 4.
