Description
Изобретение относится к области обработки металлов· давлением, в частности к устройствам для индукционного нагрева заготовок при изготовлении изделий с удлиненной осью, например коленчатых валов.The invention relates to the field of metal processing · pressure, in particular to devices for induction heating of billets in the manufacture of products with an elongated axis, for example crankshafts.
Известно устройство для индукционного нагрева, содержащее основной цилиндрический индуктор с витками ne-|Q ременного шага и установленный соосно с нйм вспомогательный индуктор. £1] .A device is known for induction heating, comprising a main cylindrical inductor with turns of ne- | Q belt pitch and an auxiliary inductor installed coaxially with the thim. £ 1].
Недостатком известного устройства является большой расход электроэнергии и длительность нагрева заготовки. С целью повышения экономичности, в устройстве для индукционного .нагрева, содержащем основной цилиндрический индуктор с витками переменного шага и установленный соосно с ним вспомогательный индуктор, последний жестко соединен с основным индуктором, а обмотка основного индуктора выполнена с шагом, уменьшающимся в направлении к вспомогательному йндук-25 тору.A disadvantage of the known device is the high power consumption and the duration of heating the workpiece. In order to increase efficiency, in a device for induction heating containing a main cylindrical inductor with variable pitch coils and an auxiliary inductor installed coaxially with it, the latter is rigidly connected to the main inductor, and the winding of the main inductor is made with a step decreasing in the direction of the auxiliary inductor 25 torus.
На чертеже изображено устройство, общий вид.The drawing shows a device, General view.
Устройство содержит основной индуктор 1, вспомогательный индуктор 2,30The device comprises a main inductor 1, an auxiliary inductor 2.30
Жестко соединенный с основным. Нагреваемая заготовка, например коленчатый вал, содержит уже выкованную левую часть, состоящую из шатунной шейки 3 и двух щек 4, и цилиндрическую частьRigidly connected to the main. The heated billet, for example a crankshaft, contains an already forged left part, consisting of a connecting rod neck 3 and two cheeks 4, and a cylindrical part
5. Основной индуктор 1 пПотно охватывает цилиндрическую часть 5 заготовки. Вспомогательный индуктор 2 имеет внутренний· диаметр, определяемый размерами щек 4. На участке 6 основного индуктора витки более сжаты, чем на участке 7, в данном случае длина Участка 6 составляет примерно половину диаметра цилиндрической части 5 заготовки. .'5. The main inductor 1p sweat covers the cylindrical part 5 of the workpiece. The auxiliary inductor 2 has an inner diameter determined by the size of the cheeks 4. In section 6 of the main inductor, the turns are more compressed than in section 7, in this case, the length of Section 6 is approximately half the diameter of the cylindrical part 5 of the workpiece. . '
Необходимо, чтобы питание совпадало по фазе в обоих индукторах 1 и 2. Индуктор 2 нагревает щеку 4, но так как эта щека не может иметь слишком высокой температуры, питание индуктора 2 управляется независимо от питания индуктора 1. Если, например, оба индуктора 1 и 2 включены одновременно, то индуктор 2 отключается раньше индуктора 1, чтобы обеспечить заданное распределение температуры, в частности одинаковую температуру в кующейся части по обеим сторонам обрабо-It is necessary that the power supply is in phase in both inductors 1 and 2. Inductor 2 heats jaw 4, but since this jaw cannot have too high a temperature, the power of inductor 2 is controlled independently of the power of inductor 1. If, for example, both inductors 1 and 2 are turned on at the same time, the inductor 2 is turned off before the inductor 1 in order to ensure a predetermined temperature distribution, in particular the same temperature in the forging part on both sides of the processing
тайной части с диаметром меньшим, чем диаметр части 5 заготовки.secret part with a diameter smaller than the diameter of the part 5 of the workpiece.
Индукторы 1 и 2 могут быть покрыты теплоизоляционными обкладками и могут иметь отверстие 8 для пиромё^рйчёско-' го наблюдения. ’Inductors 1 and 2 can be coated with heat-insulating plates and may have a hole 8 for pyrometric observation. ’
Индукторы могут быть смонтированы на подвижной каретке.Inductors can be mounted on a movable carriage.
