Description
ны рычаги 11 и 12, которые соединены с валами 3 и 4 посредством шпонок 13 и 14here are levers 11 and 12, which are connected to shafts 3 and 4 by means of keys 13 and 14
Оси 15 рычагов 11 и 12 совпадают с большими ос ми эксцентриков 5 и 6, Эти оси вместе с линией, соедин ющей оси вра щени валов 3 и 4, образуют приблизительно пр мой угол.The axes 15 of the levers 11 and 12 coincide with the large axes of the eccentrics 5 and 6. These axes, together with the line connecting the axes of rotation of the shafts 3 and 4, form an approximately right angle.
Оба рычаГа 11 и 12 соединены друг с другом резьбовой т гой, у которой часть 16 снабжена поршнем, а часть 17 - цилкндром . Обе части имеют резьбовые участки , ОД1Ш - с правой, другой с левой резьбой , наход щиес в зацеплении с соответствующей внутре1-шей резьбой ползунов 18 и 19, которые с помощью болтов 20 и 21 закрепл ютс с возможностью поворота в рычагах. Часть 17 т ги снабжена буртом, который с обеих сторон прилегает к стационарному опорному кронштейну 22 и тем самым фиксируетс в аксиальном направлеНИИ 4 С помощью подаваемой через отверстие 2 3 рабочей жидкости поршень удерлшваетс в рабочем положении. Рабоча жидкость с помощью приводимого от электродвигател 24 насоса 25 подаетс через обратный клапан 26 по трубопроводу, соединенному с гидроаккумул тором 27.Both levers 11 and 12 are connected to each other by a threaded rod, in which part 16 is provided with a piston, and part 17 is provided with a cylinder. Both parts have threaded sections, OD1Sh - with the right, the other with the left thread, which are in engagement with the corresponding internal thread of the sliders 18 and 19, which are fixed with the possibility of turning in the levers with the help of bolts 20 and 21. Part 17 of the tire is provided with a shoulder, which is on both sides adjacent to the stationary support bracket 22 and thereby fixed in the axial direction. 4 With the help of the working fluid supplied through the opening 2 3, the piston is kept in the working position. The working fluid is driven by the electric motor 24 of the pump 25 through the check valve 26 through a pipeline connected to the hydraulic accumulator 27.
Давление рабочей жидкости устанавливаетс соответственно максимально допускаемому усилию прокатки посредством регулирующего клапана 28.The pressure of the working fluid is set according to the maximum allowable rolling force by means of a control valve 28.
Корпуса 9 и 10 с помощью цапфы 29 фиксируютс в продольном отверстии 30 станины 2 в горизонтальном направлении. iTO исключает возмоншость их качательного движени .The bodies 9 and 10 are fixed by means of the axle 29 in the longitudinal opening 30 of the bed 2 in the horizontal direction. iTO excludes the possibility of their swinging movement.
Устройство работает следующие/ образом.The device works as follows / manner.
При врацдении частей 16 и 17 т ги в правом или левом направлении с помощью шарнирного вала 31 от электродвигател (на чертеже не показан) рычаги 11 и 12 поворачиваютс до тех пор, пока валки не займут свое необходимое рабочее положение До тех пор, пока рабоча жидкость воздейст вует на поршень, часть 16 т ги и рычаг 12,.а гем самым таюке и нижний валок 32 удерживаютWhen parts 16 and 17 tons are driven in the right or left direction with the help of the articulated shaft 31 from the electric motor (not shown), the levers 11 and 12 rotate until the rolls take up their required working position. It acts on the piston, a part of 16 tons of gi and a lever 12,. a hem to the most taju and the lower roller 32 hold
с в установленном положении. Если усилие прокатки превышает допускаемую величину, открываетс регулирующий клапан 28, Благодар этому давление в цилиндре уменьшаетс . При этом часть 16 т ги перемещаес в направлении, указанном стрелкой, благодар чему рычаг 12 поворачиваетс , и нижний валок 32 удал етс от верхнего валнка 33. Таким образом можно устанавливать допускаемое усилие прокатки и надежно исключить возможность перегрузки всех деталей стана.with in the set position. If the rolling force exceeds the permissible value, the control valve 28 is opened. Due to this, the pressure in the cylinder decreases. At the same time, a portion of 16 tons is displaced in the direction indicated by the arrow, whereby the lever 12 rotates and the lower roller 32 moves away from the upper shaft 33. In this way, the permissible rolling force can be established and reliably exclude the possibility of overloading all the mill parts.
В рамках изобретени можно модифицировать устройство так, что возможно регулирование радиального положени только одного валка относительно другого. В этом случае верхний валок устанавливаетс стационарно , причем тогда шарнирный вал 31 непосредственно соедин етс с цилиндром, а необходимость в рычаге 11 и ползуне 19 отпадает.In the framework of the invention, it is possible to modify the device so that it is possible to adjust the radial position of only one roll relative to the other. In this case, the upper roller is installed stationary, and then the hinge shaft 31 is directly connected to the cylinder, and the need for a lever 11 and a slider 19 is no longer necessary.
