Description

В патенте № 122423 описан способ производства асбестоцементных трубчатых изделий с внешними ответвлени ми, например отводов , тройников и т. п. фитингов, путем вьшрессовки их изнутри в формах эластичным сердечником, выполненным в виде резинового мешка. По этому способу заготовку дл  издели  из листового асбестоцемента формуют на предварительно напр женном сердечнике, накладыва  на него соответствующий слой исходного материала. Затем заготовку укладывают в форму и повышением в полости сердечника давлени  упругой среды ведут прессование заготовки с доведением ее до требуемой размерности и плотности готового издели .Patent No. 122423 describes a method for the production of asbestos-cement tubular products with external branches, such as bends, tees, and fittings, by cutting them from the inside into forms with an elastic core made in the form of a rubber bag. In this method, the blank asbestos cement product is molded onto a prestressed core, applying a suitable layer of raw material on it. Then, the preform is placed in a mold, and by increasing the pressure of the elastic medium in the cavity of the core, the preform is compacted to the required dimension and density of the finished product.

Предложение улучшает способ производства асбестоцементных трубчатых изделий с ответвлени ми за счет облегчени  укладки заготовки В форму и извлечени  сердечника из издели  без их повреждений.The proposal improves the method of producing asbestos-cement tubular products with branches by facilitating the laying of the billet into the mold and removing the core from the product without damaging them.

Достигаетс  это тем, что на концевые части сердечника надевают упругие эластичные колпаки с продольными канавками на их внутренних цилиндрических стенках, предназначенными дл  удалени  воздуха из полости колпака, и уменьшают диаметр концевых частей сердечника.This is achieved by the fact that elastic end caps with longitudinal grooves on their inner cylindrical walls, designed to remove air from the cap cavity, are put on the end portions of the core and reduce the diameter of the end portions of the core.

На чертеже показана концева  часть сердечника в продольном разрезе.The drawing shows the end portion of the core in a longitudinal section.

Концева  часть сердечника состоит из раздуваемого резинового сердечника /, на конец которого надевают упругий эластичный колпак 2 с бортом 3. Уменьшение диаметра концевой части сердечника достигаетс  тем, что внутренний диаметр колпака имеет размер меньший внутреннего диаметра издели , а внешней поверхностью колпака образуетс  раструб издели .The end portion of the core consists of an inflatable rubber core /, at the end of which a resilient elastic cap 2 with a side 3 is put on.
