Работа устройства. Включением ла зерного прибора 1 , фикс атора геометрической оси, образуетс горизонтальный луч толщиной 0,3-2,0 мм, который проектируетс строго по оси калибров на п тно 4 экрана 3. За/гем 5, поверхность которых соответствует профилю калибра клетей, устанавливают в калибр и регулируют положение последних так, чтобы луч лазера прошел через их отверсти и полностью спроецирбвалс на п тне . При этом калибр будет установлен в требуемом положении. Если стан имеет несколько клетей, то калибр валков второй клети и всех последующих настраиваю аналогично. .The operation of the device. By turning on the laser device 1, a fixed axis of the geometric axis, a horizontal beam with a thickness of 0.3-2.0 mm is formed, which is designed strictly along the axis of the calibers on the 4th screen of screen 3. For / hem 5, the surface of which corresponds to the profile of the stand gauge, in the caliber and adjust the position of the latter so that the laser beam passed through their holes and fully projected on the spot. At the same time, the caliber will be installed in the required position. If the mill has several stands, then the caliber of the rolls of the second stand and all subsequent ones are set up in the same way. .
Пример конкретного осуществлени An example of a specific implementation
Перед клетью стана устанавливают лазерный прибор ЛГ-56, снабженный коллиматором дл фиксйровани луча лазера на экран в виде рубинового п тна диаметром 0,5-2,0 мм, трубу за.крепл ют на трубе прецизионного нивелира НА-1 при помощи Двз призм с возможностью регулировки их припомощи микрометрического винта. Углова расходимость луча лазера,снабженного коллиметром с 12-кратным увеличением, составл ет 50 угловых секунд, что даже, на рассто нии 50 м обеспечивает видное п тно диаметром 2 мм. Диаметр рубинового п тна на экране 3, установленном за клетью, не превышает 1 мм. После точной фокусировки луча лазера на п тно 4 экрана в вал кйклети стана устанавливают и закрепл ют шаблон 5 в строго горизонтальном положении. Регулировку :положени калибра ведут до тех пор, йбка луч лазера не проходит через отверстие шаблона и не совпадает С п тном экрана.In front of the mill stand, an LG-56 laser device, equipped with a collimator for fixing the laser beam to a screen in the form of a ruby spot with a diameter of 0.5-2.0 mm, is fastened to the tube on the NA-1 precision level tube using Dvr prisms the ability to adjust them using micrometer screw. The angular divergence of the laser beam, equipped with a 12-fold magnification collimeter, is 50 arc-seconds, which even at a distance of 50 m provides a visible spot with a diameter of 2 mm. The diameter of the ruby spot on the screen 3 installed behind the cage does not exceed 1 mm. After a precise focusing of the laser beam on the point 4 of the screen into the shaft of the cycle, the template 5 is mounted and fixed in a strictly horizontal position. Adjustment: the position of the gauge is maintained until the laser beam passes through the pattern hole and does not match the screen spot.
Наружна поверхность шаблона соответствует профилю калибра настраиваемьтх валков, а по его центральной оси, совпадающей с осью калибра , имеетс сквозное отверстие, равное или большее диаметра луча ла;зера на допускаемое отклонение прфил калибра.The outer surface of the template corresponds to the gauge profile of the adjustable rolls, and along its central axis, which coincides with the axis of the gauge, there is a through hole equal to or greater than the beam diameter; this corresponds to the permissible deviation of the gauge profile.
Применение предложенного технического решени приводит к сокращению времени настройки валков в 3-4 раза и снижениютрудозатрат на 20%.The application of the proposed technical solution leads to a reduction in the setting time of the rolls by 3-4 times and reducing labor costs by 20%.
