Description

Способ выклейки обшивок на бакелитовой пленке представл ет ценность в смысле повышени  качества обшивок и упрош.ени  технологии их изготовлени .The method of pasting the casings on a bakelite film is of value in terms of improving the quality of casings and the simplification of their fabrication technology.

Бакелитова  пленка нашла широкое применение в изготовлении лишь плоских листов {авиафанеры), изготовление же изделий более сложных форм представл ет большие трудности , вследствие того, что уложить на пуансон подлежаший прессованию сухой шпон, обладаюший большой упругостью, ие П|редставл етс  возможным, а существуюш,ие пневмопрессы дл  этой цели не приспособлены .Bakelite film has found wide application in the manufacture of flat sheets (aviapans), but the manufacture of products of more complex shapes presents great difficulties, due to the fact that it is possible to put dry veneer with high elasticity on the punch that is pressed, and that it is possible , pnevmopressy for this purpose are not adapted.

Предлагаемый способ выклейки обшивок из шпона состоит в том, что полосам шпона при укладке их на пуансон придают необходимую форму, заранее зафиксировзнную в приспособлении.The proposed method for gluing veneer skins is that the veneer strips, when placed on the punch, are given the necessary shape, fixed in advance in the device.

Технологи  изготовлени  лобовой обшивки крыла самолета схематически может быть представлена следующим образом.The technology of manufacturing the frontal skin of an airplane wing can be schematically represented as follows.

На вспомогательном дерев нном шаблоне,  вл юш,емс  по форме дублером рабочего пуансона, производитс  фиксаци  формы скомплектованных полос шпона. Фиксаци  осуществл етс  методом контактной , дл  чего поверхность вспомогательного шаблона в местах резких переходов (малых радиусов ) нагреваетс  до требуемой температуры специальным устройством , а высушиваемый шпон в этих же местах (или весь) перед наложением на шаблон увлажн етс  до 30%,On the auxiliary wood template, which is made in the form of a double of the working punch, the shape of the assembled veneer strips is fixed. Fixation is carried out by the contact method, for which the surface of the auxiliary template in places of sudden transitions (small radii) is heated to the required temperature with a special device, and the dried veneer in the same places (or all) is moistened up to 30% before applying to the template

Процесс увлажнени  шпона и фиксаци  его формы занимают всего несколько минут.The process of moistening the veneer and fixing its shape takes only a few minutes.

Каждый слой зафиксированного по форме шпона в требуемой последовательности переноситс  на решетчатый легкий каркас, внешн   конфигураци  которого соответствует рабочему пуансону.Each layer of fixed veneer in the required sequence is transferred to a grating lightweight frame, the external configuration of which corresponds to the working punch.

Укладка на пуансон скомплектованного шпона с заранее приданной ему формой не представл ет трудности и дает возможность уложить его в плотный пакет с проложенной между сло ми бакелитовой цленкой.Laying the assembled veneer on the punch with the shape previously given to it does not present any difficulties and makes it possible to lay it in a tight package with a bakelite ruff laid between the layers.

Дл  предотвращени  возможных смешений шпон закрепл етс  в требуемом положении при помощи смоченных кусочков бакелитовой пленки, методом точечной склейки или другим доступным способом.To prevent possible mixing, the veneer is secured in the desired position with the help of wetted pieces of bakelite film, splicing method or other available method.

Запрессовка набранного таким образом плотного и хорошо облегающего пуансон пакета затрудненийPressing in a tight pack that is tight and well fitting

Предмет изобретени  Способ прессовани  фанерных изделий (например, обшивок крыльев самолетов и тому подобного) изThe subject of the invention is a method of pressing plywood products (e.g. aircraft wing skins and the like) from

слоев фанеры, склеенных бакелитовой пленкой, отличающийс  тем, что каждому слою шпона предварительно придают заданную форму издели , а затем накладывают слои один на другой, прокладыва между ними бакелитовую пленку, и: прессуют их обычным пор дком.layers of plywood glued with bakelite film, characterized in that each layer of veneer is preliminarily given a predetermined shape of the product, and then put layers one upon another, laying between them a bakelite film, and: pressing them in the usual order.
