Description

относительно конусных роликов 5, сжима  пружину 3 упором 8.relative to the tapered rollers 5, compressing the spring 3 by the stop 8.

После захода вальцовки в трубу на необходимую глубину переключают привод на обратный ход, вслед за тем плавающий конусный стерлсень 4 зат гиваетс , и вальцовка начинает развальцовывать трубу. Полное зат гивание плавающего конусного стержн  4 закончитс  тогда, когда калибрующа  часть конусных роликов 5, перемеща сь вместе с корпусом 1 в трубе, войдет в зону трубной доски. Дальнейщее зат гивание плавающего конусного стержн  4 ограничиваетс  соответствующим положением в корпусе 1 резьбового толкател  6. Диаметр окружности расположени  конусных роликов 5 сохран етс  неизменным в процессе вращени  вальцовки до окончани  вальцовани  и выхода ее из трубы.After rolling into the pipe to the required depth, the drive is switched to reverse, then the floating tapered rod 4 is tightened, and the rolling begins to flare the pipe. Full tightening of the floating cone rod 4 will end when the calibrating part of the tapered rollers 5, moving together with the body 1 in the pipe, enters the area of the tube plate. Further tightening of the floating cone rod 4 is limited to the corresponding position in the housing 1 of the threaded plunger 6. The diameter of the circumference of the tapered rollers 5 remains unchanged during the rolling operation until the end of the rolling and its exit from the pipe.

Настройка вальцовки дл  получени  необходимого размера внутреннего диаметра трубы после развальцовки устанавливаетс Adjusting the rolling to obtain the required size of the inner diameter of the pipe after flaring is established

с помощью резьбового толкател  б вворачиванием или выворачиванием его из корпуса 1 с последующи.м фиксированием винтом 7. using a threaded pusher b by screwing it in or turning it out of body 1, followed by fixing the screw 7.
