Description

(51) ШПИЛЬКА(51) STICKER

тор, состо щий из медной трубы 1, верхнего токоподвода 2 и нижнего посеребренного медного скольз щего электроконтакта 3 с плоской пружиной 4. В полость медной трубы 1 помещена еще одна труба 5. Индуктор в отверстии шпилькисо стороны верхнего токоподвода дистанционируетс  изол ционной втулкой 6, а с другой стороны неносредственно штепсельным контактом 3. Заглушка 7 служит базой дл  измерени  выт жки шпильки.A torus consisting of a copper pipe 1, an upper current supply 2 and a lower silver-plated copper sliding electrical contact 3 with a flat spring 4. Another pipe 5 is placed in the cavity of the copper pipe 1. The inductor in the stud hole of the upper current lead is spaced by an insulating sleeve 6, on the other hand, it is not directly connected with the plug contact 3. The plug 7 serves as a base for measuring the hairpin drawing.

Электрический ток 4500-5000 А промышленной частоты 50 Гц напр жением 4,6-4,8В, подводимый к индуктору через верхний токоподвод и пижний штепсельный контакт, позвол ет производить разогрев до 500°С шпильки М72 длиной 350 мм с осевым отверстием диаметром 13,5 мм за 3,5 мин.An electric current of 4500-5000 A at an industrial frequency of 50 Hz with a voltage of 4.6-4.8 V supplied to the inductor through the upper current lead and the pinch pin contact allows heating up to 500 ° C of a M72 stud with a length of 350 mm and an axial orifice diameter of 13, 5 mm in 3.5 minutes

Так как в процессе разогрева тепло выдел етс  непосредственно в теле шпильки, а индуктор водоохлаждаемый, «выбег температуры после отключени  электронагревател  отсутствует . Изменением температуры разогрева шпильки можно получить усилие зат га свыше 150 т.Since in the process of heating, heat is released directly in the body of the stud, and the inductor is water-cooled, "the temperature run out after the electric heater is turned off." By changing the temperature of heating the studs, you can get a force of more than 150 tons of hectares.
