Description

Изобретение относитс  к устройствам дл  нагрева толстостеннных труб токами высокой частоты при стыковой сварке с помощью петлеобразного индуктора.The invention relates to devices for heating thick-walled pipes with high-frequency currents during butt welding using a loop-like inductor.

Известные устройства подобного рода, индуктор которых вводитс  в зазор между торцами труб, не обеспечивают возможности быстрого , удалени  индуктора из стыка между трубами.The known devices of this kind, the inductor of which is introduced into the gap between the ends of the pipes, do not provide the possibility of quickly removing the inductor from the junction between the pipes.

В описываемом устройстве этот недостаток устранен благодар  тому, что индуктор выполнен поворотным на эксцентрично расположенной оси, удерживаетс  в зазоре между трубами собачкой и может быстро выводитьс  из зазора пружиной при нажатии педали, освобождающей Собчаку и выключающей ток.In the described device, this disadvantage is eliminated due to the fact that the inductor is pivoted on an eccentrically located axis, is kept in the gap between the pipes by the pawl and can be quickly removed from the gap by a spring when the pedal is pressed, which releases Sobchak and turns off the current.

На чертеже приведена принципиальна  схема предлагаемого устройства.The drawing shows a schematic diagram of the proposed device.

Процесс сварки производитс  в этом случае в следующем пор дке.The welding process is performed in this case in the following order.

Свариваемые детали 1 зажимают в прессе одну против другой так, чтобы между ними был равномерный зазор.The parts to be welded 1 clamp one against the other in the press so that there is a uniform gap between them.

В этот зазор ввод т петлеобразный индуктор 2 так, чтобы рассто ние между торцами и введенным индуктором было 2-3 мм. Введенный в зазор индуктор поворачиваетс  на оси,, раст гивает пружину 4 и: закрепл етс  собачкой 5. Собачка 5 соединена с пусковой педалью пресса И при включении пресса приводитс  в действие.A loop-shaped inductor 2 is introduced into this gap so that the distance between the ends and the injected inductor is 2-3 mm. The inductor inserted into the gap rotates on the axis ,, stretches the spring 4 and: is fixed by the pawl 5. The pawl 5 is connected to the starting pedal of the press.

Когда после включени  тока в цепь индуктора 2 торцы деталей / нагреютс  до сварочной температуры, включают пресс. При этом собачка 5 мгновенно освобождает защелку 6 и индуктор под действием заведенной пружины 4 выходит из промежутка нагретыми поверхност м ,и. В этот же момент включают ток, после чего торцы свариваемых деталей сдавливаютс  прессом.When, after switching on the current in the inductor circuit 2, the ends of the parts / are heated to the welding temperature, a press is turned on. At the same time, the dog 5 instantly releases the latch 6 and the inductor under the action of the actuated spring 4 leaves the gap between the heated surfaces, and. At the same time, the current is turned on, after which the ends of the parts to be welded are compressed by a press.
