Abstract
The invention relates to a rolling frame consisting of four support columns (1) that are anchored in a fixed manner to a base plate (6) and that contain axially fixed, rotatably mounted tractive spindles (3), whose upper and lower ends are provided with threads running in opposite directions, which receive the upper and lower crossmembers (4, 5) and by means of which the sets of rollers can be adjusted in opposite directions in relation to one another. The support columns (1) simultaneously guide the roller mountings (2) and receive bending blocks. The rolling frame also consists of a short-stroke setting cylinder (7), which is positioned between the lower reinforcing roller mounting (8) and the lower crossmember (5) and exerts a rolling force.
Description
Technical field
The present invention relates to a kind of mill stand and a kind of method of adjusting mill stand for Rolling Production.
Mill stand generally comprises two rolling-mill housing, and it has an adjustable roll adjusting device and an auxiliary adjusting device so that reach constant mill train axis.The framework window contraction when applying roll-force that is limited in owing to structure.Different gaps appears between rolling-mill housing and roll installed part in framework window when different roll-forces.
Background technology
By the known a kind of general mill stand of DE 21 44 511 B2, comprise the installed part that an edger roll that seals is used with framework and horizontal roller, they are bearing on entablature and the sill.Each crossbeam passes tie-bar and is interconnected to, thereby makes them and make each horizontal roller can be concentric with rolling axis or the adjustment of mill train axis, and wherein tie-bar passes framework and axial restraint and is rotatably supported in wherein.
According to the known a kind of mill stand of DE 697 12 772 T2, it comprises four pillars, each pillar and the firm grappling of a base plate and the tie-bar of the rotatable supporting of axial restraint guiding is set therein, its top and bottom are provided with reverse screw thread, each screw thread is installed crossbeam and sill, and can borrow it oppositely to adjust complete roll mutually.Each pillar is used as the guide rail of roll installed part simultaneously, short stroke is set between lower support roll assembly and sill adjusts cylinder, in order to apply roll-force.
Patent documentation US 4 712 416 A disclose a kind of cluster mill support, and it has the horizontal-shift of work roll.
Summary of the invention
The objective of the invention is to, a kind of new design principle of mill stand is provided, it does not have other servicing unit always can be transferred to a constant mill train axis again.
Reach this purpose according to the present invention by following combination of features:
Mill stand, comprise four columns, each column and the firm grappling of a base plate and respectively each tie-bar of the rotatable supporting of axial restraint guiding is set in these pillars, its top and bottom are provided with reverse screw thread, each screw thread is installed crossbeam and sill, and can borrow these screw threads oppositely to adjust complete roll mutually, wherein each column is used as the guide rail of roll installed part and the bearing of bending part simultaneously, and comprise that one is provided with short stroke and adjusts cylinder in order to apply roll-force between lower support roll assembly and sill, wherein the setting that separates in pillar reaches separating to the power transmission of the roll and the guide rail of roll installed part with the roll installed part by tie-bar.
This purpose reaches by a kind of method with adjustment mill stand of the described feature of claim 5 in addition.
Draw further by all dependent claims and to constitute.
Functional mode of the present invention is, via right-hand thread and left-hand thread make opposed each parts equably (or unevenly) move in opposite directions or away from each other mutually.Simultaneously the function of the transmission of roll-force is separated with the function of " guide rail of roll installed part ", the window that no longer goes out the phenomenon rolling-mill housing whereby shrinks such shortcoming.Go back the tendency of appreciable impact " buzzer " whereby.
Description of drawings
Below will be by description of drawings the present invention, wherein this illustrates the diagrammatic side view of the mill stand of part section.
The specific embodiment
This structure consists essentially of the column 1 of four welding, and it bears the installation of guide rail He each tie-bar 3 of each roll installed part 2.Each tie-bar 3, it transmits roll-force via lower and upper cross-member 4 and 5, and lower and upper cross-member is moved mutually in opposite directions or away from each other.Each column 1 and basis, that is base plate 6 casts in together and via foundation bolt and fixes.Realize the design of rigidity by each roll installed part 2 by load to be estimated.It is in place that each tie-bar 3 utilizes its right-hand thread and left-hand thread to move in the mill stand of stand under load not.Just adjust cylinder 7 adjustment roll-forces and under mode of operation, import each pull bar as mentioned above then via crossbeam via a short stroke.Roll-force by maximum to be estimated realizes this design.Guarantee self-locking in the Rolling Production by the little helical pitch of screw thread, the brake in wherein driving via control in addition can guarantee the position.In the entablature 4 that is opposite to short stroke adjustment cylinder 7, one additional less adjustment cylinder (not shown) can also be installed for the less power of depressing.
Each tie-bar 3 drives via four synchronous independent transmissions or via a synchronous operated drive unit with machinery.Upper and lower crossbeam 4 and 5 moves in opposite directions or away from each other according to turning to mutually of tie-bar.In this case, Aw always can be transferred to the mill train axis when each identical roller diameter (Stw, Zw, Aw).
Whole parts are production parts of being convenient to process.Another advantage is the little weight of each separate part that is used to assemble.
Claims (5)
