Claims (1)

ПАТРУБКОВ лагают два графитовых электрода, зазор между которыми равен 10 мм. На электроды от сварочного трансформатора ТС-500 подают напр жение 30 В при силе тока 100 А Оправка нагреваетс  до 900°С за 2 мин. Формула изобретени  Устройство дл  изготовлени  крутоизогнутых патрубков, содержащее полую рогообразную оправку и нагревательный элемент, отличающеес  тем, что, с целью 8 82 обеспечени  нагрева заготовок из немагнитных материалов и регулировани  температуры в процессе формообразовани , оно снабжено двум  размещенными внутри оправки подвижными вкладыщами с гибкими металлорукавами, а нагревательный элемент выполнен в виде двух закрепленных на вкладышах электродов, соединенных с источником электрической энергии. Источники информации, прин тые во внимание при экспертизе 1. Авторское свидетельство СССР № 614847, кл. В 21 D 9/12, 1975.NOZZLE lags two graphite electrodes, the gap between them is 10 mm. A voltage of 30 V is applied to the electrodes from the welding transformer TC-500 at a current of 100 A. The mandrel heats up to 900 ° C in 2 minutes. Apparatus for making bent nozzles containing a hollow horn-shaped mandrel and a heating element, characterized in that, in order to 8 82 ensure heating of blanks of non-magnetic materials and temperature control during shaping, it is equipped with two movable inserts with flexible metal pipes placed inside the mandrel, and the heating element is made in the form of two electrodes attached to the inserts connected to a source of electrical energy.
