Изобретение относитс к области изготовлени изделий из пресс-крошки.This invention relates to the manufacture of press crumbs.
Известны способы изготовлени изделий из пресс-крошки, например роликов ленточных конвейеров, путем формовани пресс-крошки в пресс-форме.Methods are known for manufacturing articles from press chips, such as belt conveyor rollers, by molding the press chips in a mold.
Цель изобретени -увеличение срока службы роликов и повышение производительности труда.The purpose of the invention is to increase the service life of the rollers and increase productivity.
Дл этого формование пресс-крошки в пресс-форме под давлением 500-700 кг/см и температуре 150-180°С производ т одновременно с сырой резиной, которую предварительно закладывают в пресс-форму и располагают на ее периферии.For this, the molding of the crumb in the mold under a pressure of 500-700 kg / cm and a temperature of 150-180 ° C is carried out simultaneously with raw rubber, which is pre-laid in the mold and placed on its periphery.
Способ осуш,ествл ют следуюш,им образом.The method of drying is as follows.
В матрицу формы закладывают сырую резину и располагают ее на ее периферии, а во внутрь закладывают древесную пресс-крошку . Форму закрывают и производ т формование ролика под давлением 500-700 кГ/см и температуре 150-180°С.Raw rubber is placed in the mold matrix and placed on its periphery, and a press crumble is placed inside. The mold is closed and the roller is molded under a pressure of 500-700 kg / cm and a temperature of 150-180 ° C.
При этом происходит вулканизаци наружного сло , полимеризаци древопресс-крошкиWhen this occurs, the vulcanization of the outer layer, the polymerization of wood-crumb
и соединение сло резины с остовом ролика, состо ш;его из древесной пресс-крошки. Процесс происходит одновременно, так как сыра древесина вулканизируетс и древесна пресскрошка полимеризуетс при одинаковых значени х давлени и температуры.and the connection of a layer of rubber with the skeleton of the roller, consisting of it from woody press chips. The process takes place at the same time, as the cheese of the wood is vulcanized and the wood powder is polymerized at the same pressure and temperature values.
Ролики, изготовленные предложенным способом , легко можно реставрировать, так как на наружный слой резины легко накладывать сырую резину и вулканизировать в формах до наружного размера.The rollers made by the proposed method can be easily restored, since it is easy to apply raw rubber on the outer rubber layer and vulcanise it in forms to the outer size.
Предмет изобретени Subject invention
Способ изготовлени изделий из древесной пресс-крошки, например роликов ленточных конвейеров, путем формовани пресс-крошки в пресс-форме, отличающийс тем, что, с целью увеличени срока службы роликов и повышени производительности труда, формование пресс-крошки в пресс-форме производ т под давлением 500-700 кг/см и при 150-180°С одновременно с сырой резиной, которую предварительно закладывают в пресс-форму и располагают на ее периферии.A method of manufacturing wood press crumb products, such as belt conveyor rollers, by molding the press crumb in a mold, characterized in that, in order to increase the service life of the rollers and increase labor productivity, the press crumb is molded under pressure of 500-700 kg / cm and at 150-180 ° C simultaneously with raw rubber, which is pre-laid in the mold and placed on its periphery.
