Background technology
The multi-roll mill of present rolling mill for hot rolled planks and strips from simple two-roller mill to complexity, of a great variety.For increasing the rigidity of milling train, the diameter of the diameter of roll, especially backing roll is increasing, its objective is the raising mill stiffness, reduces the distortion of roller system.And realize the sheet material precision of standard-required by the roll shape of complexity.Bring so a lot of disadvantageous problems: 1, the backing roll diameter is excessive, causes backing roll weight large, has increased the consumption of roll; 2, backing roll is excessive, the very large problem of bringing for the manufacturing of roll, and cost also significantly raises simultaneously; 3, along with the growth of roll length, the amount of deflection at roll center increases; 4, for reaching standard-required, need to adopt the complicated control devices such as various roll shapes and string roller, roller jointly to realize.
The utility model content:
The purpose of this utility model is exactly the problem that exists for solving above-mentioned prior art, and a kind of six-high cluster mill that reduces roll bending by the segmentation supporting way is provided.
The technical scheme that adopts is:
A kind of six-high cluster mill, comprise frame, press down system, bascule, locking device, it is upper that segmentation is supported, lower roll system forms, described press down system is depressed mechanism by two covers and is formed, be installed in the housing cap, on described, lower roll system is installed between frame, and give axial locking by locking device, on, be equiped with bascule between lower roll system, it is characterized in that described upper roller system is by upper press cover, two backing rolls and a working roll form, upper press cover and two backing rolls consist of the upper supporting system that segmentation is supported, described lower roll system is comprised of two backing rolls and a working roll and a lower bottom base, and lower bottom base and two backing rolls consist of the lower support system that segmentation is supported.
Above-mentioned backing roll is an elongated roll mandrel, N group filmatic bearing is installed on the axle, the outside, outer ring of filmatic bearing is equipped with wear-resistant sleeve, backing roll is installed in the supporting roller bearing seat, backing roll is connected with upper press cover by the gap between the adjacent filmatic bearing on the roll mandrel, upper press cover is identical with the lower bottom base structure, be a trapezoidal shape entity, the bottom of upper press cover is provided with two arc grooves parallel with roll axis, there is quantity not wait in each groove, the ribs that the position is staggered, the width of ribs is B, the width of ribs is determined according to the size of roll-force, the filmatic bearing of the backing roll of installing in the quantity of the ribs in each groove and this groove is counted N and is adapted, its quantity is N+1, the length Z of the filmatic bearing of the backing roll of installing in the distance L between the ribs in each groove and this groove adapts its distance L=Z+B+10～20mm.The structure of lower bottom base is identical with upper press cover.
A plurality of ribs in the upper press cover act on the gap between the adjacent filmatic bearing of roll mandrel, make between backing roll and the upper press cover and have formed multi-point support.The length of each supporting section has become the 1/N of backing roll length, and the roll-force in each segmentation also becomes the 1/N of the suffered roll-force of backing roll, can get thus, and the amount of deflection in each segmentation of backing roll is the N of the backing roll amount of deflection of two end supports
-4Doubly.The roller diameter of backing roll is footpath outside the wear-resistant sleeve, and its diameter is in working diameter D ± 100mm scope, and concrete size should can parameter decide by power.
A plurality of ribs interlaced arrangement in above-mentioned upper press cover and the lower bottom base act on the gap between the adjacent filmatic bearing of roll mandrel, make to consist of segmentation between backing roll and the upper press cover and support.
The filmatic bearing of two backing rolls in the above-mentioned upper and lower roll system is staggered installation of, in the length range of the gap of the adjacent filmatic bearing of one of them backing roll corresponding to the filmatic bearing of another root backing roll.
The utlity model has following advantage:
1, adopts two backing rolls of assembling form and support system that gland makes up to form to replace huge backing roll, solved thoroughly with the poor problem of plate.
2, adopt this structure, the control system of milling train is greatly simplified, equipment investment is significantly reduced.
3, adopt the milling train of this structure, can improve rolling accuracy without roller, string roller and complicated control device, make the lateral error of sheet material less than 10 μ m/m.
4, adopt the milling train of this structure, be applicable to the rolling 1000mm-5000mm roll coil of strip and medium-thick plate.
