ел Изобретение относитс  к переработке отработанных резинотехнических изделий и может быть использовано при пepepaбoт ке изношенных шин на регенераторных завоаах. Известен способ извлечени  металлических сераечников изизношенных покрышбк путем отделени  борта от покрышек, срезани  сло  резины с одной из сторон борта до сердечника и отделени  сердечника с другой части борта раздиром l Недостатком этого способа  вл етс  низка  производительность труда, так как вначале срезают слой резины, а затем уже отдел ют сердечник разциром. Наиболее близкими из известных  вл етс  способ извлечени  металлической арматуры из изношенных покрышек, при котором нагревают металлическую, арматуру до температуры оплавлени  блиале-. жаших к ней слоев резины и отдел ют ее от резины 2 . Недостатком даннаго способа  вл етс  также низка  производительность труда, так как процесс отделени  резины от арматуры составл ет 3-4 мин. Кроме того, способ сложен в осуществлении вследствие того, что нагрев производит в высокочастотном электромагнитном поле, создаваемом питаемым электрическим током индуктором, снабженным высокочастотным преобразователем. Целью изобретени   вл етс  повышени эффективности процесса извлечени  металлической арматуры, Поставленна  цель достигаетс  тем, что согласно способу извлечени  металлической арматуры из изношенных покрышек , при котором нагревают Kfeталлическую арматуру до температуры оплавлени  близлезащих к ней опоев резины и отдел ют ее от резины, переа нагревом осуществл ют зажим и оановременное наарезание покрышки с внешней и внутреннейi. сторон ее бортов до металическо туры посредством токосъемных захватов, а отделение арматуры от слоев резины производ т путем ее вырыва вышеуказанными захватами. Данный способ уменьшает врем  процесса удалени  металлических сердечников из изношенных покрышек в 9 раз, что позволит повысить производительность труда и эффективность процесса. На фиг. 1 показано устройство дл  осуществлени  предлагаемого способа; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - покрышка с токосъемными захватами . Способ осуществл етс  следующим образом . В изношенной пневматической шине 1 с одной стороны (или с двух сразу) зах- . ватывают в трех местах бортовое коль цо 2 токосъемными захватами 3, которые надрезают резинат до контактировани  с металлической арматурой (сердечником) 4, и захватывает ее. Подают напр жение: на трехфазный трансформатор 5 -и током вторичной обмотки нагревают мет,алличес- кий сердечник 4 через токосъемные захв ы 3 до температуры, при которой происходит оплавление близлежащих слоев резины. После нагрева металлический сердечник 4 вырывают из покрышки то- косъемными захватами 3. П р и м е р. В изношенной пневматической автомобильной шине, ТОСТ 4754- 74, с одной стороны захватывают в трех местах бортовое кольцо 2 токосъемными захватами 3, изготовленными из стали 40Х, которые нацрезаютч резину до контактировани  с металлическим сердечником 4. От вторичной обмотки трехфазного трансформатора 5 током в 1ОООА (напр жение 1ОВ) через токосъемные захваты 3 нагреваетс  металлический сердечник 4 в течение 10с. После нагрева сердечника 4 он легко вырываетс  токосъемными еахватами 3, Предлагаемый способ извлечени  металлической , арматуры по сравнению с известным прост в осуществлении и позвол ет повысить производительность тру- да на 8О %, а следовательно и эффективность йроцесса извлечени . .The invention relates to the recycling of used rubber products and can be used to recycle worn tires on regenerator plants. There is a known method of extracting metallic grayish from worn tires by separating the bead from the tires, cutting the rubber layer from one side of the bead to the core and separating the core from the other part of the bead tear. The disadvantage of this method is low productivity, since first the rubber layer is cut off and then the core is already separated by razir. The closest known is a method of extracting metallic reinforcement from worn tires, in which the metallic reinforcement is heated to the melting temperature of the blended. layers of rubber attached to it and separating it from rubber 2. The disadvantage of this method is also low labor productivity, since the process of separation of rubber from reinforcement is 3-4 minutes. In addition, the method is difficult to implement due to the fact that the heating produces in a high-frequency electromagnetic field created by an inductor powered by an electric current and equipped with a high-frequency converter. The aim of the invention is to increase the efficiency of the process of extracting metal reinforcement. The goal is achieved by the method of extracting metallic reinforcement from worn tires, which heat the metallic reinforcement to the melting temperature of the adjacent rubber opodes and separate it from the rubber, heating it clamping and cutting the outer and inner tires into time. the sides of its sides to metal rounds by means of collector clamps, and the separation of reinforcement from rubber layers is carried out by tearing it out with the above-mentioned grippers. This method reduces the process of removing metal cores from worn tires by a factor of 9, which will increase the productivity and efficiency of the process. FIG. 1 shows a device for carrying out the proposed method; in fig. 2 shows section A-A in FIG. one; in fig. 3 - tire with current collector grippers. The method is carried out as follows. In a worn pneumatic tire 1 on one side (or two at once) zakh-. the side ring 2 is collected in three places with current-collecting grippers 3, which incise the resins before contact with the metal armature (core) 4, and captures it. Voltage is applied: to the three-phase transformer 5 - and the current of the secondary winding is heated by meth, the allic core 4 through current-collecting grippers 3 to the temperature at which the melting of the adjacent rubber layers occurs. After heating, the metal core 4 is pulled out of the tire with a pull-on clamps 3. EXAMPLE 3. In a worn-out pneumatic automobile tire, TOAST 4754-74, on one side, in three places, the bead ring 2 is collected by current-collecting clamps 3 made of 40X steel, which cut rubber before contact with the metal core 4. From the secondary winding of the three-phase transformer 5 with 1OOAA current ( the voltage IOV) through the collector clamps 3 the metal core 4 is heated for 10 s. After the core 4 is heated, it is easily pulled out by current-collecting grips 3. The proposed method of metal extraction, fittings as compared with the known one is simple to implement and allows labor productivity to be increased by 8O% and, consequently, the efficiency of the extraction process. .
