Изобретение относитс , в частности, к технологическому процессу извлечени  спрессованного порошкообразного материала из металлической оболочки.The invention relates in particular to a process for the extraction of a compressed powdered material from a metal shell.

Известен способ разрушени  цилиндрических тел, заключающийс  в раст жении их с одновременным местным нагревом. Такой способ не позвол ет разрушить оболочку дл  извлечени  из нее порошкообразного материала.There is a known method of destruction of cylindrical bodies, which consists in stretching them with simultaneous local heating. Such a method does not allow the shell to be broken to extract the powdered material therefrom.

В цел х устранени  указанного недостатка по предлагаемому способу оболочку раст гивают и одновременно нагревают по винтовой линии.In order to eliminate this drawback according to the proposed method, the shell is stretched and simultaneously heated along a helix.

На фиг. 1 изображено изделие со сплошной рболочкой, в которой находитс  спрессованвый материал, в исходном (зажатом) положении; на фиг. 2 показано изделие после разрыва оболочки.FIG. 1 shows a product with a continuous shell, in which the pressed material is located, in the initial (clamped) position; in fig. 2 shows the product after breaking the shell.

Изделие с перерабатываемой спрессованной массой 1, наход шейс  в оболочке 2, устававливают в зажимах 3 и 4 соосно с индуктором 5, соедин емым с источником тока высокой частоты. Один из зажимов (3) неподвижен, а другой (4) может вращатьс  вокруг своей оси и совершать поступательное движение вдоль нее.The product with the recycled pressed mass 1, which is in a sheath 2, is installed in clamps 3 and 4 coaxially with an inductor 5 connected to a high-frequency current source. One of the clips (3) is stationary, and the other (4) can rotate around its axis and perform translational motion along it.

После этого концы издели  зажимают и, прилага  к зажиму 4 осевую силу, в оболочкеAfter that, the ends of the product are clamped and, applying to the clamp 4 an axial force, in the shell

создают раст гивающее напр л ение нужной величины. Затем на необходимое врем  включают высокочастотный индуктор 5. При этом узкий по сок оболочки, наход щийс  под витками индуктора, нагреваетс , и в момент, когда напр жение в оболочке становитс  больше предела прочности, она разрываетс  (вскрываетс ) по винтовой линии со смещением кромок (см. фиг. 2). Осевое усилие подбираетс  таким, чтобы разрыв происходил при температуре , при которой металл обладает низкой прочностью и высокой пластичностью.create tensile stress of the desired size. Then, the high-frequency inductor 5 is turned on for the required time. At the same time, the narrow juice of the shell, which is under the turns of the inductor, heats up, and at the moment when the voltage in the shell becomes greater than the tensile strength, it breaks (opens) along the helix with edge shift ( see fig. 2). The axial force is chosen so that the rupture occurs at a temperature at which the metal has low strength and high ductility.

В случае необходимости оболочку можно раскрутить до любого нужного диаметра, а следовательно, любой величины зазора а между кромками (витками) оболочки, а также выпр мить в ленту шириной, равной шагу между витками индуктора.If necessary, the shell can be unrolled to any desired diameter, and therefore, any gap size and between the edges (turns) of the shell, as well as straightened into a tape with a width equal to the step between the turns of the inductor.

Предмет изобретени Subject invention

Способ разрушени  полых цилиндрических тел, заключаюшийс  в раст жении их с одновременным местным нагревом, отличающийс  тем, что, с целью разрушени  оболочки дл  извлечени  из нее порошкообразного материала, ее нагрев осушествл ют по винтовой линии.The method of destruction of hollow cylindrical bodies, which consists in stretching them with simultaneous local heating, characterized in that, in order to destroy the shell to extract the powdered material from it, it is heated along a helix.
