Description

Изобретение относитс к технологии разделки электрических кабелей и может быть использовйно в электротехнической промЕзШшенностй и при переработке вторичного сырь в цветной . металлургии на участках шихтоподготовки .The invention relates to the technology of cutting electrical cables and can be used in electrical engineering and in the processing of secondary raw materials in color. metallurgy in areas of preparation.

Известен способ сн ти металлической оболочки кабел , согласно которому оболочку кабел прорезают в продольном направлении с двух противоположных сторон, раздел ют ее на две части, пропуска кабель между двух роликов, один из которых имеет выпуклую, а другой - вогнутую поверхность . . Оболочка кабел згикимаетс между роликами и ст гиваетс с кабел при вращении роликов, при этом токоведущие металлические жилы освобождаютс от оболочки Ц .A known method for removing a metal cable sheath, according to which the cable sheath is cut in the longitudinal direction from two opposite sides, is divided into two parts, the cable passes between two rollers, one of which has a convex and the other a concave surface. . The cable sheath is zigmated between the rollers and pulled off the cable as the rollers rotate, and the current-carrying metal wires are released from the sheath C.

Однако известное техническое решение не обеспечивает послойное разделение оболочки на отдельные материалы .However, the known technical solution does not provide layer-by-layer separation of the shell into individual materials.

.Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс станок дл разделки электрических кабелей . в основу работы которого заложен технологический процесс заключающийс в томThe closest to the invention in technical essence and the achieved result is a machine for cutting electrical cables. which is based on the technological process consisting in

что кабель деформируют до получени овальной формы, прорезают оболочки с двух противоположных сторон в плос- . кости большой оси овсша и отдел ют токоведущие жилы от стальной брони и металлической трубы 21.that the cable is deformed to an oval shape, the sheaths are cut from two opposite sides into a flat surface. the bones of the major axis of the oats and separate the current-carrying conductors from the steel armor and the metal pipe 21.

Однако этот способ не обеспечивает послойное разделение защитного покрыти кабел . Ввиду того, что защит10 ное покрытие, как правило, содержит двойное сТсШьное покрытие, металлическую трубу из свинца или алюмини , то переработка оболочки требует их разделени по видам материалов, в However, this method does not provide a layer-by-layer separation of the cable protective coating. Due to the fact that the protective coating, as a rule, contains a double wrap, a metal pipe made of lead or aluminum, the processing of the casing requires their separation according to the types of materials

15 частности разделение от стали, осуществление которого сопр жено с трудност ми , вызванными завальцованием кромок реза половинок оболочки. Все это усложн ет технологию.15, in particular, separation from steel, the implementation of which is associated with the difficulties caused by rolling the cut edges of the shell halves. All this complicates technology.

Цель изобретени - упрощение технологии .The purpose of the invention is to simplify the technology.

Поставленна цель достигаетс тем, что перед отделением токов дующих жил от стальной брони и металличес25 кой трубы стальную броню сдвигают с металлической трубы и сплющивают кабель, располага токоведущие жилы в один р д.The goal is achieved by the fact that, before separating the currents of blowing veins from steel armor and metal pipe, steel armor is shifted from the metal pipe and flattens the cable, having current-carrying conductors in one row.

Claims

30 is carried out as follows. The cable in the armored protective sheath is deformed to obtain an oval shape. In this case, the difference in the lengths of the major and minor axes of the oval should be at least two times the thickness of the protective sheath of the cable to be cut. the shell, without touching the conductor. Simultaneously with the deformation of the cable shell, the protective sheath is cut through to the current-carrying veins in the plane of the major axis of the oval. Steel bronze under the influence of its elastic forces is partially exfoliated from the metal pipe of the protective sheath. Partially flaking steel armor shears are shifted along the cable axis at a speed exceeding the cable feed rate for deformation and penetration, for example, 1.5 times or more by contact with a moving movable surface .. Due to the applied friction forces, these half sheaves are separated from the metal pipe of the protective shells and discarded forward, i.e. A twisted steel wire separates from the cable sheath. In order to facilitate the separation of the cut twisted steel armor, it is advisable to heat the cable surface to 35-40 ° C, for example, by blowing, with hot air. The metal pipe with live conductors that is free from steel armor and flattened to the wires is flattened, having current conductors in one row. At the same time, straightening of the pipe strips into flat tapes covering the flat C of the tokoedukadih veins on both sides occurs. The strips are separated from the cores by mechanical means. This method ensures the separation of the cable's protective sheath for non-ferrous metals and non-ferrous metals, therefore there is no need for metallurgical separation. Claims The method of cutting electrical cables is predominantly in an armored protective sheath, including the deformation of the cable to an oval shape, cutting the shell from two opposite sides in the plane of the major axis of the oval and separating the conductor from the steel GpoKK and the metal pipe, , before separating the current-carrying veins from the steel armor and the metal pipe, the steel armor is shifted from the metal pipe and flattens the cable, with the current-carrying wires one row.
