Работа устройства осуществл етс следующим образом.The operation of the device is as follows.
После соударени с концентратором 2 волока 4, деформиру материал 6, движетс против хода волочени до полной остановки. В это врем усилие волочени измен етс от максимального значени до нул . Сигнал с датчика 8 измерител усили волочени поступает на вход усилител 5 и с его выхода на вход блока 10 управлени , который в момент, когда усилие волочени снижаетс до нулевого значени , лодает кратковременный импульс питающего напр жени на катущку 5 электромагнита , В остальное врем питающее напр жение на электромагнит не подаетс . Б результате волока 4, расположенна в обойме 5, мгновенно прит гиваетс к торцу концентратора 2 и, получив импульс силы Б направлении, противололожном направлению волочени , начинает деформировать материал. Дальще процесс повтор етс .After the collision with the concentrator 2, the portage 4, by deforming the material 6, moves against the course of the dragging to a complete stop. At this time, the drag force varies from maximum value to zero. The signal from the sensor 8 of the drag gain meter enters the input of the amplifier 5 and from its output to the input of the control unit 10, which, at the moment when the drag force drops to zero, lasts a short-term supply voltage pulse on the electromagnet roller 5, The electromagnet is not supplied. As a result, the die 4, located in the holder 5, is instantly attracted to the end face of the concentrator 2 and, having received an impulse of force B in the direction opposite to the direction of dragging, begins to deform the material. The process is repeated.
В результате уменьщени времени возврата волоки к торцу концентратора возрастает эффективность использовани энергии ультразвуковых колебаний. Это позвол ет увеличить скорость волочени на 20- 25% по сравнению с известным техническим рещением.As a result of a shorter return time to the end of the concentrator, the efficiency of using the energy of ultrasonic vibrations increases. This makes it possible to increase the dragging speed by 20-25% as compared with the known technical solution.

Сердечником электромагнита служит сам концентратор.The core of the electromagnet is the hub itself.
Наличие обоймы предотвращает разрушение волоки в момент соударени с концентратором .The presence of the cage prevents the destruction of the die at the time of the impact with the hub.
