Description
Изобретение касаетс усовершенствовани индуктора дл индукционного нагрева кромок вырубных штампов и тому подобных изделий токами высокой частоты.The invention relates to an improvement in the inductor for the induction heating of the edges of punch dies and the like with high frequency currents.
Сущность изобретени по сн етс чертежом.The invention is illustrated in the drawing.
Устройство состоит из плиты /, разделенной радиальными прорезами 2 на сектора, электрически -соедин емые контактами 3, скольз щими вдоль прорезов.The device consists of a plate / divided by radial slits 2 into sectors electrically connected by contacts 3 sliding along the slits.
Подвижные контакты устанавливаютс соответственно конфигурации нагреваемого издели 4, которое устанавливаетс на плиту и изолируетс от последней тонким слоем изол ции (например, слюды).The movable contacts are installed according to the configuration of the heated product 4, which is installed on the plate and is insulated from the latter by a thin layer of insulation (for example, mica).
В таком устройстве ток высокой частоты будет протекать в основном по внутренним, обращенным друг к другу поверхност м секторов. Это объ сн етс тем, что индуктивное сопротивление внешнего контура всегда больше сопротивлени внутреннего контура, так как коэфициент самоиндукции контура с током пропорционален его диаметру.In such a device, the high frequency current will flow mainly along the inner, facing each other surfaces of the sectors. This is due to the fact that the inductive resistance of the external circuit is always greater than the resistance of the internal circuit, since the coefficient of self-induction of the circuit with the current is proportional to its diameter.
Если на поверхность секторов через тонкую изол ционную прослойку наложить замкнутый контур (например , вырубной штамп 4), то наименьшее кажущеес сопротивление , вследствие вли ни индуктивности вторичного контура, а следовательно , и наибольша концентраци тока будет иметь место непосредственно по контуру наложенного штампа.If a closed circuit is imposed on the surface of the sectors through a thin insulating layer (for example, a die 4), the least apparent resistance due to the influence of the secondary circuit inductance and, consequently, the greatest concentration of current will take place directly along the contour of the imposed stamp.
Режуща часть штампа, изолированна от плиты тонким сдоем слюды, нагреваетс в течение короткого времени, не вызыва прогрева внутренних слоев штампа.The cutting part of the stamp, isolated from the plate by a thin mica mica, is heated for a short time without causing the internal layers of the stamp to warm up.
Предмет изобретени Индуктор дл индукционного нагрева кромок вырубных штампов и тому подобных токам1И высокой частоты, отличающийс тем, что, с целью использовани одного и того же аппарата дл нагрева режущих частей изделий различных конфигураций, он выполнен в виде плиты, составленной из нескольких металлических (преимущественно медных) секторов, разделенных радиальными прорезами и электрически соедин емых скольз щими вдоль этих прорезов контактами , которые устанавливаютс соответственно конфигурации нагреваемого издели , накладываемого на плиту с тем, чтобы обеспечить протекание тока в секторах по пути, определ емому конфигурацией издели .The subject of the invention is an inductor for induction heating of the edges of punch dies and the like of high frequency currents, characterized in that, in order to use the same apparatus for heating the cutting parts of products of various configurations, it is made in the form of a plate composed of several metal (mainly copper ) sectors separated by radial slots and electrically connected by sliding along these slots contacts, which are set according to the configuration of the heated product, superimposed on the plate in order to ensure the flow of current in the sectors along the path determined by the configuration of the product.
