(54) РАБОЧАЯ КЛЕТЬ СТАНА КОСОЙ ПРОКАТКИ ТРУБ(54) WORKING STICK KOSA ROLLING PIPE

1one

Изобретение относитс  к области трубопрокатного производства.The invention relates to the field of pipe production.

Известны станы, рабочие клети которых имеют стшшну, рабочие валки с ос ми, размещенными в горизонтальной нлоскости , и направл ющие диски, закрывающие сверху и снизу очаг деформацш 1 .Mills are known, whose working stands are scrolled, work rolls with axes placed in a horizontal plane, and guide discs covering the deforming center 1 above and below.

Износ дисков требует своевреме1шой их смены. Однако наличие привода вращени  дисков и монтаж их сверху и сгшзу от оси прокатки делает эту операцию продолжительной по времени и трудоемкой .Worn discs require timely replacement. However, the presence of a drive for rotating the discs and mounting them from above and from the rolling axis makes this operation time consuming and laborious.

Известна рабоча  клеть стана косой прокатки труб, имеюща  станину, в которой смонтированы диаметрально противоположно два рабочих валка и два приводных в сьемных корпусах направл юид}х диска 2.A working stand of an oblique rolling tube mill is known, having a frame in which two working rolls and two drive rolls in detachable bodies of the disk} x 2 are diametrically opposed to each other.

Смену направл ющих дасков осуществл ют заменой корнусов, что несколько облегчает смену верхнею диска, ни требует много времени на смену нижнего.The change of guide dusks is carried out by replacing the corns, which somewhat facilitates the replacement of the upper disk, nor does it take much time to change the lower one.

На фиг. 1 изображена предложе1ша  рабоча  клеть, поперечный разрез; на фиг. 2 - то же, горизонтальный разрез на высоте направл ющих дисков.FIG. 1 shows the proposed working stand, cross section; in fig. 2 is the same horizontal incision at the height of the guide discs.

Клеть включает сташшу 1, размещенные в ней диаметрально противоположно верхний 2 и нижний 3 приводные рабочие валки и направл ющие приводные диски 4, вертикальный вал 5 каждого из которых установлен на поворотном относительно вертикальной оси 6, закрепленной на станине в эксцентпиковой втулке 7, рычаге 8, свободный конец которого благодар  регулировочному винту 9, накидной скобе 10 с Щ1линдром 11 прижаты к ста1шне с возможностью регулировани  зазора . На рычагах смонтированы приводы вращели  12 направл Ю1цих дисков.The cage includes scrap 1, placed in it diametrically opposite the upper 2 and lower 3 drive work rolls and guide drive discs 4, the vertical shaft 5 of each of which is mounted on a rotary relative to the vertical axis 6 fixed to the frame in the eccentric bushing 7, the lever 8, the free end of which, thanks to the adjusting screw 9, the cap strap 10 with the cylinder 11, is pressed to the station with the possibility of adjusting the gap. The levers mounted drives rotated 12 directional disks.

Рабоча  работает следующим образом.Working works as follows.

При прокатке задают заготовку 13 в клеть и деформируют на оправке 14 валками 2 и 3, вращаюишмис  в одну сторону, и расположе1шыми в окнах статшы 1 нш1равл ющ 1ми дисками 4, которые привод тс  во Bpauienne приводом 12 через зубчатые передачи.When rolling, the workpiece 13 is set into a cage and deformed on the mandrel 14 by the rollers 2 and 3, rotated in one direction, and placed in the windows of the stats 1 and 1 disks 4, which are driven in Bpauienne by the drive 12 through gears.

Дл  замены направл ющих дисков 4 цилиндры 11 ст гиваютс  назад, скобы 10 поворачиваютс  таким образом, что рычаги 8 поворачиваютс  в эксцентриковых втулках 7 и даски выступают из окон станины, к ним обеспечиваетс  свободный доступ.In order to replace the guide discs 4, the cylinders 11 are retracted, the brackets 10 are rotated so that the levers 8 rotate in the eccentric bushings 7 and the plates protrude from the windows of the frame, and they are freely accessible.

Расположение валков друг над другом, а дисков справа и слева значительно упрощает смену последних, а поворотные рычаги обеспечивают доступность и наладку.The arrangement of the rolls one above the other, and the discs on the right and left greatly simplifies the change of the latter, and the pivoting levers provide accessibility and adjustment.
