Abstract

Предлагается способ формирования облицовки кумулятивного заряда посредством литья под давлением, при этом составляющие материала облицовки включают порошковый металл и органическое связующее вещество. Компоненты смеси для формования облицовки смешивают, после чего перерабатывают в устройстве для литья под давлением, а затем выталкивают из него в пресс-форму, в которой облицовке придается нужная форма. Связующее вещество детали в форме облицовки подвергается разрыву связей как механическим, так и химическим путем. Механический путь разрыва связей предусматривает нагрев, а химический - обработку детали в форме облицовки раствором для растворения и удаления из нее компонентов связующего вещества. Способ формирования облицовки кумулятивного заряда не включает спекания. При применении настоящего способа могут также использоваться необработанные заготовки, производимые в устройстве для литья под давлением, которые не подверглись разрыву связей. Настоящий способ может также быть использован для формирования оболочки кумулятивного заряда, который может включать добавочный этап спекания.
