Description
Technical field
The utility model belongs to the changing rig of cold-rolling mill, is specially adapted to online various cold-rolling mills need change intermediate calender rolls and working roll the time, realizes lifting fast roll changing track in a kind of milling train of fast roll changing.
Background technology
At present, make cold-rolled steel sheet and develop into the cold continuous rolling that pickling and milling train constitute jointly production line from monovolume is rolling, in cold continuous rolling, adopt four-high mill and six-high cluster mill usually, they are to support respectively with bearing block on the frame, the lower support roller, on, following intermediate calender rolls, on, bottom working roll, wherein four-high mill is not installed, following intermediate calender rolls, because in cold-rolled process, these rollers are because of frayed, often need roll change, therefore be equiped with the fortune roller track that roll change is used in the frame outside, when the needs roll change, have to or by hand, or with lifting, the loop wheel machine tool promotes the required roll body that changes, and is carried to then on the fortune roller track.Not only taken a lot of work effort but also can not fast roll changing of the mode of this roll change especially in the associating unit, owing to wear very difficulty of band, and can not be shut down completely again during normal roll change, thereby can not adapt to normal streamline production, and influence the raising of production efficiency.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, project organization is reasonable and provide not only, can realize fast roll changing, be applicable to online roll change again, just reduce roll changing time widely, and having the production efficiency height, handling safety is used lifting fast roll changing track in a kind of very easily milling train.
The purpose of this utility model is to adopt following technical scheme to realize: lifting fast roll changing track in the milling train, comprise frame, top backing up roll, last intermediate calender rolls, top working roll, bottom working roll, following intermediate calender rolls, lower support roller and fortune roller track characteristic are: its structure is by last intermediate calender rolls roll change track, the hydraulic cylinder lowering or hoisting gear, top working roll roll change track, cylinder piece lowering or hoisting gear, bottom working roll roll change track, roll change track and lower support roller roll change track are formed in the middle of following, corresponding with last intermediate calender rolls top, parallel with the intermediate calender rolls longitudinal axis, installing on the frame of last intermediate calender rolls both sides parallel on intermediate calender rolls roll change track, be in installing hydraulic cylinder lowering or hoisting gear on the side, two ends of every outer roll change track of frame; The top working roll roll change track corresponding with the top working roll top, that installing parallels on the frame of top working roll both sides, the place, two sides that is in every roll change track on the frame installs cylinder piece lowering or hoisting gear; Corresponding with the bottom working roll bottom, parallel with the working roll longitudinal axis, the track of the bottom working roll roll change that installing parallels on the frame of bottom working roll both sides; Corresponding with following intermediate calender rolls bottom, the track of intermediate calender rolls roll change under symmetry installing on the frame of following intermediate calender rolls both sides; Corresponding with lower support roller bottom position, the track of symmetry installing lower support roller roll change on the frame below lower support roller bottom.
Described each hydraulic cylinder lifting, guider, form by track, hydraulic cylinder, connecting rod, gathering sill, guide post, install hydraulic cylinder on the side in the frame outside, an end of the external part articulated linkage of hydraulic cylinder piston rod, the other end of connecting rod are hinged on the bearing of frame; On the frame of hydraulic cylinder piston rod front the installing can make guide post import in it gathering sill.
Described each cylinder piece lowering or hoisting gear; Forms by cylinder piece, piston rod, cylinder cap, cylinder are stifled, be processed with the bar hole of matching with piston rod in the cylinder piece, at the end dress cylinder cap in bar hole, other end dress cylinder blocks up, and the external part of its piston rod is connected in the bottom surface of top working roll roll change track.
Principle of the present utility model and operation are described below: because four-high mill and six-high cluster mill are all to adopt hydraulic pressure to push to technology, realize online roll change, its bottom working roll, intermediate calender rolls and the just necessary decline of lower support roller down, therefore, bottom working roll, following intermediate calender rolls have been adopted independent roll change track separately respectively, its bottom working roll, following intermediate calender rolls are under the drive of pushing to hydraulic cylinder, just can drop on the roll change track separately, but wherein the bottom working roll of four-high mill drops on the track of bottom working roll; This moment bottom working roll, down the inner roll change track of the milling train of intermediate calender rolls just in time the fortune roller track with working roll, intermediate calender rolls is relative, but wherein the roll change track of the bottom working roll of four-high mill just in time the fortune roller track with working roll is relative.For last top working roll, because the requirement of online roll change, top working roll must rise, therefore lifting, the guiding hydraulic cylinder of work roll changing track have been installed in the bend pipe system of milling train, when the needs roll change, by hydraulic cylinder its roll change track and bearing block thereof are together lifted arrival roll change position, also play guide effect simultaneously.Same principle because cylinder piece lowering or hoisting gear has been installed on last centre, make intermediate calender rolls also have can lifting the roll change track.So, just reduce roll changing time widely.Combine the above technical measures of being taked, realize the purpose of this utility model.
Compared with prior art, the utility model not only project organization is reasonable, can realize fast roll changing, is applicable to online roll change again, just reduces roll changing time widely, and has the production efficiency height, and handling safety is used advantages such as very convenient.
