The specific embodiment
The structure of work roll shifting device of the present invention can be referring to Fig. 8, comprise a fixed block 5, described fixed block 5 is installed on the body of equipment, one end of fixed block 5 connects an end of a traversing cylinder 6, an other end and a movable block 7 of traversing cylinder 6 fix, described movable block 7 is positioned at a side of described fixed block 5 and described traversing cylinder 6, is not connected the bearing block of working roll on the described movable block 7 with a side of described traversing cylinder 6 contacts with described fixed block 5.
The situation that work roll shifting device of the present invention is installed on the equipment can be referring to shown in Figure 9, the bearing block outside of described working roll 3 is provided with groove, being vertically installed with the working roll locking device 8 that protrude the termination on the described movable block 7, matches with described groove in the termination of described working roll locking device 8.Can lock working roll 3 like this and move, make device more reliable with movable block 7.
As Fig. 8, Fig. 9 with shown in Figure 10 as described in movable block 7 with as described in working roll 3 bearing block by direction with as described in the vertical roller cylinder 9 of traversing cylinder 6 directions be connected, one end of described roller cylinder 9 is connected on the described movable block 7, and the other end connects the bearing block of described working roll 3.
As shown in figure 11, the termination of the end that described traversing cylinder 6 is connected with described fixed block is provided with a diameter and becomes big prominent 10 suddenly, described prominent 10 outer surface is a sphere, described fixed block and traversing cylinder 6 junctions are provided with accommodation section 11, the bore of described accommodation section 11 openends is less than described prominent 10 diameter, the inner surface of described accommodation section 11 is a sphere, described prominent 10 is comprised in the described accommodation section 11, and described prominent 10 outer surface cooperates with the internal surface gaps of described accommodation section 11.When equipment work makes,, therefore may produce some deformation because working roll bears very big stress.Between fixed block and traversing cylinder, be provided with said mechanism, make traversing cylinder and fixed block universal hinging,, can play the effect that buffering connects, thereby improve the performance and the life-span of equipment when deformation takes place because of stressed at working roll or other parts.
Working roll moving device provided by the present invention, the action of the traversing and roller of the roller of can finishing the work at work is to improve the plate shape of rolled plate.As shown in figure 12, when the piston of traversing cylinder is moved, on the axial direction of working roll, carry out horizontal moving with driving working roll 3.In practical operation, because the width of rolling steel plate 2 can not be total identical with the width of working roll 3, therefore, after working long hours, if just carry out the rolling of steel plate with the single position of working roll, it is inhomogeneous to cause working roller abrasion to consume, and when reprocessing the steel plate of other specification, will cause the inhomogeneous of steel plate rolling quality.Used Working roll moving device provided by the present invention, because working roll can laterally move, so just can control the uniformity of working roller abrasion by such moving, not only prolong the service life of working roll, can also improve the crudy of different size steel plate.
In the process of steel plate rolling, owing to be subjected to various stress influence, the phenomenon that both sides upwarp can take place in steel plate.Working roll moving device provided by the present invention also has the function of roller.As shown in figure 13, can so that working roll when rolling, by the roller cylinder two ends of working roll 3 are applied the power on the vertical direction, make the working roll in the vertical direction that a bending take place, the pressure that is subjected in the middle of thereby the pressure that feasible steel plate 2 both sides that are rolled are subjected to is greater than, and then solved the problem that the steel plate both sides upwarp.
