Description
Technical field
The present invention relates to a kind of rolling device, described rolling device has at least two work rolls, described work roll is bearing in rolling support by means of at least one work roll installed part respectively, wherein, in order to set the roll seam of expectation, at least one in work roll in described rolling support is with respect to another work roll, particularly vertically, adjustable, wherein, there is axial moving device, described work roll can move up at the axle of work roll with respect to rolling support by described axial moving device, wherein, described axial moving device has the operating element of the axis coaxle setting of the work roll moving with need, and, wherein, at least one work roll is connected in effective with bending apparatus, can apply bending moment to described work roll by described bending apparatus.
Background technology
By the rolling device of known a kind of this class of EP 1 436 104 B1.The roll device of the disclosure is furnished with axial moving device, thereby makes work roll move to desired axial location and to be fixed on there along its axial length.The axial moving device that is implemented as piston-pumping cylinder device of hydraulic pressure has piston, and described piston is fixed on supporting arm with one in its end, and described piston can be on rolling support vertically slides up and down with together with the installed part of work roll.
In addition, before known rolling device also there is bending apparatus, work roll can be subjected to bending moment by described bending apparatus.Described bending apparatus is supported between the installed part of work roll and the installed part of adjacent back-up roll.Instantly work roll is vertically when minute movement, and described bending apparatus is supported between the thickening part on the installed part of lower work roll and the crossbeam of rolling support.
Therefore, in the version by the known rolling device of EP 1 436 104 B1, the axial moving device being arranged on coaxially on work roll installed part that moves through of work roll is realized, and described axial moving device shifts out in the time changing work roll together with roll stacks from rolling support.Work roll-bending apparatus is implemented as " cantilevered ", and in described device, upper work roll-installed part is supported in the U-shaped accommodation section of upper back-up roll-installed part by bending and balance pumping cylinder.At this, described bending pumping cylinder can be arranged in work roll-installed part, or is alternatively arranged in back-up roll-installed part.
In this version, advantageously, arrange and can realize larger roll upward stroke (being for example 1200mm to the maximum) according to " cantilevered " of described upper work roll.This allows the thicker stick of rolling on such rolling support.In addition, described work roll-movement and bending apparatus can shift out in the time changing roll stacks from rolling support, and in described rolling support outside, it are safeguarded.Thus, for operator, can save in order to safeguard this device the downtime on equipment.
Due to the arranged concentric in roll stacks, axial moving device should not absorb any tilting moment that conventionally needs consideration in the mobile system being arranged on still on rolling support.This size to mobile device produces active influence, because the locomotivity needing is less.
But disadvantageously, during work roll is mobile vertically, the bending pumping cylinder of the upper back-up roll-installed part of described upper work roll group by being subjected to equalizing pressure is pushed in this version.Frictional force in this appearance produces tilting moment, and described tilting moment may make back-up roll-installed part tilt.When after moving at described work roll, support is imposed suddenly roll-force (" open rolling impact "), therefore can not get rid of following situation, on back-up roll bearing arrangement-contact oil drag bearing in the situation that-bearing insert and journal bush are local, may cause damage of the bearing because edge pushes this, or each bearing series is born too high load in the situation that using rolling bearing.
Also known a kind of bending apparatus, described device forms according to the form of " curved cover ".At this, relate to a kind of work roll-bending apparatus, in this bending apparatus, in hydraulic pressure block, be provided with so-called " curved cover ", described " curved cover " guaranteed in rolling support and in the case of high rolling upward stroke the good guiding of work roll-installed part and realized the movement to relevant work roll simultaneously.
For making device that work roll moves vertically be fixed on of two roll mill seat supports.At this, for each lateral bolster support member (" mobile hanger ") of relevant work roll-installed part is distributed a mobile pumping cylinder unit.Work roll-installed part is vertically arranged in described mobile pumping cylinder unit movably.
The advantage of this version is can realize until be approximately the rolling upward stroke of 550mm.In addition, do not have moment to be delivered in back-up roll bearing arrangement by applying described " curved cover " when the mobile working roll.In addition, advantageously, do not need the connection of additional medium pipeline because described bending apparatus and mobile device regularly pipe connect.
But in this design disadvantageously, because mobile device is arranged in bracket upright post and outside due to the power that requires described mobile device to occur in must being absorbed in the operation of rolling in the case of high rolling upward stroke, thus produced mobile device stretching, extension and heavy and expensive embodiment thus.
Summary of the invention
