Description
В ОСНОВНОМ патенте № 122423 описан способ производства асбсстоцементных трубчатых изделий с внешними ответвленн ми, например отводов , тройников и т. п. фитингов, путем выпрессовки их изнутри в формах , с применением эластичного сердечника, выполненного в виде резинового мешка, размеры которого мен ют введением в его полость среды под давлением. По этому способу заготовку дл издели из листового асбестоцемента формуют на предварительно напр женном сердечнике, который после наложени на него соответствующего сло исходного материала укладывают в форму и повышением в его плоскости давлени упругой среды ведут прессование заготовки с доведением ее до требуемой размерности и плотности готового издели . Дл придани оконечност м сердечника относительной жесткости на ни.х надевают упругие эластичные втулки с фланцами на торцах.The main patent No. 122423 describes a method for the production of asbestos-cement tubular products with external branches, for example bends, tees, etc. fittings, by pressing them out from the inside in forms using an elastic core, made in the form of a rubber bag, the dimensions of which change by insertion in his cavity of the medium under pressure. According to this method, the blank asbestos cement product is molded on a prestressed core, which, after applying a suitable layer of raw material onto it, is placed into a mold and, by increasing the pressure of the elastic medium in its plane, press the blank to bring it to the desired dimension and density of the finished product. In order to impart to the ends of the core of relative rigidity, elastic elastic sleeves with flanges on the ends are put on the Nx.
Описываемое изобретение вл етс развитием указанного выше способа и имеет целью облегчить операции укладки в форму сердечника и извлечени его из полости отформованного издели путем уменьшени диаметра концевых частей сердечника. Достигаетс это тем, что на предварительно надетые на них эластичные втулки надевают упругие эластичные колпаки с продольными канавками на их внутренних цплиндрн ческих стенках.The described invention is a development of the above method and is aimed at facilitating the operations of stacking in the shape of the core and removing it from the cavity of the molded product by reducing the diameter of the end portions of the core. This is achieved by the fact that elastic bushings previously put on them are put on elastic elastic caps with longitudinal grooves on their inner cylindrical walls.
На чертеже в разрезе изображена концева часть сердечника при прессовании издели .The drawing in section shows the end portion of the core during extrusion of the product.
Дл уменьшени диаметра концевой части сердечника /на нее надевают втулку 2, наружный диаметр которой соответствует внутреннемуTo reduce the diameter of the end portion of the core /, a sleeve 2 is put on it, the outer diameter of which corresponds to the inner
диаметру формуемого издели . На втулку 2 надевают колпак 3, который образует раструб издели . Колпак имеет на своих внутренних цилиндрических стенках нродольлыс канавки дл выхода из по. ости колпака воздуха при надевании его на втулку.diameter of the molded product. On the sleeve 2 put on the cap 3, which forms the socket of the product. The cap has on its inner cylindrical walls nrodolllyz grooves to exit from. awnings of an air cap when putting it on the sleeve.
