На чертеже изображено устройство дл .осуществлени предлагаемого способа .The drawing shows a device for implementing the proposed method.
Способ может быть осуществлен следующим образом.The method can be carried out as follows.
Резинотехнические издели 1 с металлической арматурой помещаиот в высокочастотное электромагнитное поле , создаваемое питаемым электрическим током индуктором 2, снабженным высокочастотным преобразователем 3. Температуру на контактирующей с резиной поверхности арматуры определ ют с помощью установленной в индукторе 2 металлической трубки 4 и термопар 5 и 6, расположенных соответственно внутри и снаружи металлической трубки. Включают высокочастотный преобразователь 3 на полную мощность при этом через индуктор 2 протекает максимальный высокочастотный ток, а в металлической арматуре изделий навод тс вихревые токи, которые ее нагревают. При этом масса арматуры по всей глубине прогреваетс неравномерно , так как индукционные токи высокой частоты н основном концентрируютс на поверхности металла,Rubber products 1 with metal fittings are placed in the high-frequency electromagnetic field created by an electric current-fed inductor 2, equipped with a high-frequency converter 3. The temperature on the rubber-contacting surface of the fittings is determined using the metal tube 4 and thermocouples 5 and 6 arranged in the inductor 2 and arranged accordingly inside and outside of the metal tube. The high-frequency converter 3 is turned on at full power while the maximum high-frequency current flows through the inductor 2, and eddy currents are induced in the metal fittings of the products, which heat it. At the same time, the mass of the reinforcement is unevenly heated throughout the depth, since high-frequency induction currents mostly concentrate on the metal surface,
Арматуру нагревают до приобретени контактирующей с резиной ее поверхностью заданной температуры, при которой происходит оплавление близлежащих слоев резины. При обработке изделий со стальной арматурой заданную температуру выбирают в пределах 350-400°С.The armature is heated until its surface is in contact with a predetermined temperature, at which the melting of the adjacent rubber layers occurs. When processing products with steel reinforcement, the set temperature is chosen in the range of 350-400 ° C.
При нагреве контактирующей с резиной поверхности арматуры до (температура определ етс по трубке 4) происходит автоматическое ограничение температуры в пределах 350400 0 с помощью высокочастотного преобразовател 3, которым ограничивают питающий ток индуктора и в систему управлени которого поступает сигнал отрицательной обратной св зи, снимаемый с термопары 6. Арматуру нагревгиот до заданной температуры по всему ее поперечному сечению при ограничении питаккцего тока индуктора вследствие увеличени сигнала, снимаемого с термопары 5.When heating the rubber-contacting surface of the reinforcement to (temperature is determined by tube 4), the temperature is automatically limited to 350,400 ° C by means of a high-frequency converter 3, which is limited by the inductor supply current and the control system receives a negative feedback signal taken from the thermocouple 6. The armature of heating to a predetermined temperature throughout its cross section while limiting the supply current of the inductor due to an increase in the signal taken from the thermocouple 5.

По сигналу термопары 5 отключаетс высокочастотный преобразователь 3. Одновременно подаетс напр жение на электромагнитный клапан 7, который открывает доступ охлаждающей воде к трубке 5. Трубка 5 охлаждаетс до первоначальной температуры и сигнал термопары б через систему управлени высокочастотным преобразователем отключает электромагнитный клапан 7. Индуктор опрокидывают и резина 8 и арматура 9, которые вследствие оплавлени уже не св заны друг с другом , высыпаютс на .поддон, установленный на транспортере 10. Металлическую арматуру 9 сортируют, охлаж- дают и отправл ют на дробеструйнуюThe 350-400 ° C reinforcement of the products 1 is heated over the entire cross section up to 350-400 seconds, and the rubber layers adjacent to the reinforcement are melted. The signal of thermocouple 5 turns off high-frequency converter 3. At the same time, voltage is applied to solenoid valve 7, which opens cooling water to tube 5. Tube 5 is cooled to its initial temperature and the signal of thermocouple b turns off solenoid valve 7 through the control system of high-frequency converter rubber 8 and reinforcement 9, which, due to melting, are no longer connected to each other, pour onto the pallet mounted on the conveyor 10. Metal reinforcement 9 is sorted, is cooled and is sent to shot blasting to
