Description
Широко известны электрические нагревательные устройства индукционного типа, в которых нагреваемое изделие образует вторичную обмотку трансформатора. Предметом насто щего изобретени вл етс способ извлечени из таких приборов нагретых изделий.Electric induction type heating devices are widely known, in which the heated product forms the secondary winding of a transformer. The subject of the present invention is a method for extracting heated products from such devices.
Согласно изобретению, дл облегчени извлечени издели , из нагревательного прибора, используютс электродинамические усили , возникающие между первичным током в неподвижной катущке прибора и вторичным током, возбужденным в изделии.According to the invention, in order to facilitate the removal of the product from the heater, electrodynamic forces arising between the primary current in the fixed coil of the device and the secondary current excited in the product are used.
Сущность изобретени по сн етс прилагаемым чертежом.The invention is illustrated in the accompanying drawing.
На фиг. 1 изображен поперечный разрез нагревательного прибора индукционного типа дл местного нагрева изделий; на фиг. 2 - вид этого прибора сверху.FIG. 1 shows a cross-section of an induction type heater for local heating of products; in fig. 2 is a top view of this device.
Прибор представл ет собою электромагнит переменного тока с магнитопроводом / и обмоткой 2, питаемой однофазным током нормальной (или иной) частоты. The device is an AC electromagnet with a magnetic core / and a winding 2 fed by a single-phase current of normal (or other) frequency.
Подлежащее нагреву изделие 4 вводитс через кольцег-ую щель в магнитопроводе / и образует как бы вторичную обмотку. При питании обмотки 2 переменным током вторичный ток проходит главным образом по цилиндрической части издели , производ местный нагрев; часть издели вне магнитопровода не нагреваетс .The product 4 to be heated is introduced through a ring-shaped slot in the magnetic core / and forms a sort of secondary winding. When the winding 2 is supplied with alternating current, the secondary current passes mainly through the cylindrical part of the product, producing local heating; the part of the product outside the magnetic circuit is not heated.
Дл защиты первичной обмотки от нагревани лучистой теплотой ус,т.анавливаетс экран 3 из теплоизол ционного материала.In order to protect the primary winding from being heated by radiant heat, the screen, the screen 3 of the heat insulating material, is set off.
Вследствие несимметричного расположени первичной обмотки и издели при прохождении тока возникают электродинамические усили , стрем щиес вьполкнуть изделие из прибора; поэтому изделие 4 при нагреве удерживаетс прижимом 6, укрепленным на каркасе 5 и снабженным ручкой с защелкой 7.Due to the asymmetrical arrangement of the primary winding and the product, as the current passes, electrodynamic forces arise that tend to push the product out of the device; therefore, the product 4 is held by the clamp 6, which is fixed on the frame 5 and provided with a handle with a latch 7, when heated.
По окончании нагрева ток выключают, прижим 6 отвод т в сторону и кратковременно включают ток, в результате чего изделие 4 выталкиваетс из прибора. At the end of heating, the current is turned off, the clamp 6 is retracted to the side and briefly switches on the current, as a result of which the product 4 is pushed out of the device.
