The specific embodiment
As shown in Figure 1, on a roll change buggy WW, laying by comprise horizontal roller HWO on one and once horizontal roller HWU horizontal roller to and be arranged on the bearing block LV of the vertical roller between them and the roll stacks that constitutes of the bearing block LU of horizontal roller HWU down.
These parts of roll stacks are locking mutually so overlappingly: (also see Fig. 2) on roll change buggy WW, laying each external strut and internal overarm support STA, STI.Outer strut STA be placed on down the both sides of horizontal roller HWU roll neck WZ and can unclamp and can change other bearing length strut STA the clamping plate HL that is fixed fix, and internal overarm support STI (also seeing Fig. 3) is inserted into down among the bearing block LU of horizontal roller HWU (Fig. 3), and its lower end is installed in and is loaded among the roll change buggy WW and removable bearing sleeve TH that have different support height goes up (Fig. 2,4).
The free upper end of strut STA, STI is charged in the guide groove FR of two downwardly facing openings, and the trend of described guide groove (not shown) is parallel to each other and the bottom surface of vertical roller bearing block LV is loaded in the described guide groove.
Among the interval slot SA (Fig. 5) on the upper surface of vertical roller bearing block LV, among that the supporting pin SB that packed into, the free end of pin are contained in a downwardly facing opening and the tank AA in last horizontal roller HWO bearing block LO bottom surface.In tank AA (Fig. 6) have one that bear spring force and can vertically move press piece DS, it has outstanding edge RB, a vertical end face SF down and a horizontally extending placed side AF (also seeing Fig. 7,8) is arranged behind edge RB.
As Fig. 9-shown in Figure 12, each depression stroke of vertical roller and position thereof are determined by the axial backing plate of bearing block and the block AS that releasably is installed in its guide groove FR.According to these positions, supporting pin SB is inserted in the interior corresponding slot SA of bearing block LV upper surface.
The roll stacks that is placed on the roll change buggy WW is moved in the unshowned framework memorial archway of universal frame, in this roll stacks, following horizontal roller HWU is connected with the bearing block LV interlocking of vertical roller with internal overarm support STI with outer strut STA and is connected with last horizontal roller HWO interlocking by supporting pin SB.In addition, vertical roller bearing block LV by also unshowned in framework memorial archway side guidance and upwards leave a bit of distance of free end in the bearing block LV guide groove FR of charging into of strut STA, STI, they can move freely and allow thus the motion of depressing of vertical roller bearing block LV subsequently in guide groove FR.In addition, as shown in Figure 7, last horizontal roller HWO and the piece DS that presses that is positioned in the tank AA of its bearing block LO are placed on the supporting pin SB that charges into tank AA with its placed side AF together.
Subsequently, when preparing to be rolled operation, last horizontal roller HWO has been lifted such degree by unshowned top roll balanced controls, and promptly vertical roller bearing block LV can move freely also with the supporting pin SB that is standing level below last horizontal roller HWO bearing block LO and can be brought into predetermined depressing position.If do like this, then go up horizontal roller HWO and can be reduced to as shown in Figure 8 rolling position.Here, insert supporting pin SB in the tank AA again with towards the ramp that presses piece DS and overcome spring pressure ground back pressure and press piece, be locked in one on the convex shoulder behind this inclined-plane up to it, this convex shoulder has the vertically-guided face, the front that presses piece DS just abuts on this spigot surface, as a result, press the front of piece DS and the spigot surface of supporting pin SB and be received in rolling middle the moving both vertically between last horizontal roller HWO bearing block LO and vertical roller bearing block LV that occurs.
By this structure, the whole depression stroke district of vertical roller may be used to rolling operation.This is to the hydraulic press down system particular importance, and in hydraulic press down system, the cylinder stroke is because positioning accuracy is former thereby must keep as far as possible for a short time.Owing in vertical roller, often increase the depression stroke district and under the situation that the distance of distance trunnion axis bearing remains unchanged and the roll change position that has nothing in common with each other at the vertical axis bearing must occur, so can come horizontal adjusting supporting pin and block under the horizontal adjusting abreast with it according to plate thickness by backing plate.The horizontal roll change position of following horizontal roller can obtain equilibrium by the backing plate under strut in roll change buggy.The different roll changes position of last horizontal roller can compensate by the backing plate under the supporting pin or by various supporting pin length.The differing heights of vertical roller bearing block can come balance by corresponding different backing plates simply.
