Abstract

FIELD: mechanical engineering; mining equipment. SUBSTANCE: outline of scraper conforms to outline of initial scraper and it is provided with pockets made for displacement of metal in amount equal to amount of metal lost by scraper as a result of wear. To make metal scraper first of all acceptable outline of wear is determined, then worn scraper is measured and its size is compared with acceptable outline of wear, then worn out scraper is heated to plastic deformation temperature and is placed between dies to form scraper with initial outline. EFFECT: enlarged operating capabilities. 4 cl, 6 dwg

Изобретение относится к скребку, применяемому в горном оборудовании, который выполнен из изношенного скребка, а также к способу получения такого скребка. Скребок имеет внешнюю конфигурацию, идентичную конфигурации первоначального скребка, и карманов, которые выполняют для вытеснения объема металла, по меньшей мере равного объему, утерянному в результате износа скребка. Для изготовления металлического скребка предварительно определяют приемлемый контур износа, измеряют изношенный скребок и определяют соответствие его контуру износа, затем нагревают изношенный скребок до определенной температуры штамповки, помещают скребок между штампами и формируют скребок с первоначальной внешней конфигурацией.The invention relates to a scraper used in mining equipment, which is made of a worn scraper, as well as to a method for producing such a scraper. The scraper has an external configuration identical to the configuration of the original scraper, and pockets, which are performed to displace a volume of metal at least equal to the volume lost as a result of wear of the scraper. For the manufacture of a metal scraper, an acceptable wear contour is preliminarily determined, a worn scraper is measured and its wear contour is determined, then the worn scraper is heated to a certain stamping temperature, the scraper is placed between the dies and the scraper is formed with the initial external configuration.
