Description

Устройство работает следующим образом .The device works as follows.

При отклонении полосы по толщине вследствие-увеличени  давлени  прокатки по вл ютс  гофры (на одной или обеих кромках. Во врем  прокатки осуществл ют регулировку профил  рабочих валков 21 и 22, котора  заключаетс  в том, что к кромке с гофрами перемещают конической концевой частью опорный валок первого р да до исключени  гофра. Управление синхронно работающими плунжерными гидроцилиндрами осуществл етс  реверсивным золотником -через обратные управл емые клананы. Синхронизаци  достигаетс  тем, что рабоча  жидкость, поступа  в полость , например, правого гидроцилиндра, перемещает его плунжер, опорный валок и нлунжер левого гидроцилиндра, вытесн   из его полости рабочую жидкость на слив через дроссель, регулирующий скорость перемещени  и создающий подпор иа сливе. При прекращении подачи рабочей жидкости полости плунжерных гидроцилиндров запираютс  обратными управл емыми клапанами , нри этом возможно как индивидуальное , так и попарное (верхн  , нижн   пары) перемещение опорных валков.When the strip deviates in thickness due to an increase in rolling pressure, corrugations appear (on one or both edges. During rolling, the profile of work rolls 21 and 22 is adjusted, which means that an anvil roll moves to the edge with corrugations by a conical end portion the first row to the exclusion of the corrugation. The synchronous working plunger hydraulic cylinders are controlled by a reversible spool through reverse controlled clans. Synchronization is achieved by the fact that the working fluid entering the cavity, For example, the right hydraulic cylinder, moves its plunger, support roll and hydraulic cylinder of the left hydraulic cylinder, displaces the working fluid from its cavity to drain through the throttle, which regulates the speed of movement and provides support to the drain This is possible both individually and in pairs (upper, lower pair) movement of the support rolls.
