The utility model content
For overcoming the shortcoming of existing strip-mill strip bend roller connecting device, the utility model provides a kind of strip-mill strip bend roller connecting device, the adverse consequences of having avoided existing strip-mill strip bend roller connecting device structural disadvantages to produce effectively.
Technical solution of the present utility model is: a kind of strip-mill strip bend roller connecting device, comprise by string roller hydraulic cylinder, locking hydraulic cylinder, latch, move that seat, holder, pull bar, briquetting form two go here and there roller mechanism and by four roller mechanisms that the roller hydraulic cylinder is formed, be arranged in the both sides of upper and lower working roll bearing block; Described string roller mechanism is divided into fore side and transmission side two parts, and connects into integral body with pull bar, connects with working roll bearing block, frame respectively; Described roller hydraulic cylinder is located at by string roller Driven by Hydraulic Cylinder and does on the mobile seat of axial displacement; It is characterized in that: string roller hydraulic cylinder, both are separation members to move seat, and string roller hydraulic cylinder is bolted in and moves on the seat.
Described string roller hydraulic cylinder, locking hydraulic cylinder, latch are located at fore side.
The mobile seat of described fore side is connected with working roll bearing block locking by locking hydraulic cylinder, latch.
Be provided with alignment pin and bearing thereof between the mobile seat of described fore side and the frame.
Described mobile seat and working roll bearing block, the briquetting and the holder that are fixed on the frame are slidingly matched, and respectively the face of being slidingly matched is provided with slide plate.
Described roller hydraulic cylinder piston club head is spherical, with the working roll bearing block crimping.
Owing to adopted said structure, the utlity model has following beneficial effect:
1. in the string roller process, there is not relative displacement between roller hydraulic cylinder and the working roll bearing block, the roller hydraulic cylinder is not subjected to horizontal force action, be not easy to produce and leak, roller hydraulic cylinder long service life, workroll bearing and roller cylinder force invariant position, shaft strength is good, unbalance loading not, long service life.
2. difficulty of processing is little, and cost is low, and mounting or dismounting are convenient, for ease of maintenaince.
3. need only change the damage parts, needn't integral replacing, use cost reduces.
Describe the utility model in detail below in conjunction with embodiment and accompanying drawing.

The specific embodiment
Referring to Fig. 1 to Fig. 4:
The utility model is formed two string roller mechanisms by string roller hydraulic cylinder 9, locking hydraulic cylinder 10, latch 24, mobile seat 13, holder 19, pull bar 14, briquetting 15, the string roller mechanism is divided into fore side and transmission side two parts, connect into integral body with pull bar 14, be arranged in the both sides of upper and lower working roll bearing block 12 respectively.Form four roller mechanisms by eight roller hydraulic cylinders 11, be located at respectively on the mobile seat 13 of upper and lower string roller mechanism fore side and transmission side.
The roller hydraulic cylinder 11 of fore side, string roller hydraulic cylinder 9, locking hydraulic cylinder 10, all be located on this side shifting seat 13, moving seat 13 is " L " shape, have two orthogonal installed surfaces, the cylinder body of roller hydraulic cylinder 11 is directly processed on horizontal mounting surface, and string roller hydraulic cylinder 9 is installed on the vertical mounting surface.Piston rod and this side frame 3 of string roller hydraulic cylinder 9 are affixed, and roller hydraulic cylinder 11 piston rod heads are spherical, with this side shaft holder 12 crimping of working roll.Moving seat 13 is axially locked working roll bearing block 12 by the latch 24 that locking hydraulic cylinder 10 drives.Be provided with bearing 21 between this side shifting seat 13 and the frame 3, be provided with alignment pin 20 between bearing 21 and the mobile seat 13.
The roller hydraulic cylinder 11 of transmission side, its cylinder body are directly processed on this side shifting seat 13, and piston rod head is spherical, with this side shaft holder 12 crimping of working roll.
Two side shifting seats 13 are connected with the two ends of pull bar 14 respectively, and are slidingly matched with each self-corresponding working roll bearing block 12, briquetting 15, holder 19, and respectively the face of being slidingly matched is respectively equipped with slide plate 16,17,18,23; Both sides holder 19, briquetting 15 are fixed in respectively on the frame 3.
This device 6 and top backing up roll bascule 1, screwdown gear 2, frame 3, top backing up roll device 4, top working roll device 5, bottom working roll device 7, the lower support roller arrangement 8 common strip-mill strips of forming.
The course of work of this device 6 is:
After leading to pressure oil in the roller hydraulic cylinder 11, piston rod stretches out, compress upper working rolls and lower working rolls bearing block 12 respectively, make the backing roll generation flexural deformation to a certain degree in working roll, top backing up roll device 4 and the lower support roller arrangement 8 in top working roll device 5 and the bottom working roll device 7, adjustment pressure size, can adjust the degree of working roller bending distortion, thereby reach control panel shape, improve the purpose of strip shape quality.
After feeding pressure oil in the string roller hydraulic cylinder 9, driving mobile seat 13 moves axially on holder 19, because locking hydraulic cylinder 10, latch 24 are locked top working roll device 5, bottom working roll device 7 and are moving on the seat 13, so top working roll device 5 and bottom working roll device 7 also move axially.The direction of action that sets in advance because of upper and lower string roller hydraulic cylinder 9, thus upper and lower working roll axially move in opposite directions or oppositely, thereby improve the working roller abrasion situation, increase service life, prolong the replacement cycle, realize the milling train free rolling.
In the time of need not going here and there rolling system, fore side is moved the pin-and-hole that the locating hole 22 of seat on 13 aimed at bearings 21, insert alignment pin 20, make bend roller connecting device 6 and frame 3, can realize a roller, not go here and there rolling system in the axial locking location.
