The specific embodiment
As Fig. 1, shown in 2, present embodiment comprises that the plain-barreled roll roller is 1,2 up and down, and the edger roll roller is 3,4, transmission side and fore side memorial archway 5,6, the horizontal yoke 7,8 of transmission side and fore side.
As Fig. 1, shown in 2, horizontal roller 1,2 is rolling bearing up and down, bears radial rolling power by four row cylindrical roller bearings, and thrust bearing bears axial force.Have two wing plates (importing and exporting direction respectively at rolled piece) near collars one side on the fore side bearing block of last horizontal roller 1 and following horizontal roller 2, it leans against on the inner surface of 6 two columns of fore side memorial archway by the self-alignment pad.On the fore side bearing block away from collars one side have two up and down straight-through skewed slots (rolled piece import and export direction each one), four hydraulic cylinders are housed on the outer surface of 6 two columns of fore side memorial archway, the plate that drives four band inclined-planes respectively inserts in the skewed slot of bearing block, thereby horizontal roller 1,2 is fixed on the memorial archway up and down.
Be provided with worm screw-screw pair mechanism in the fore side bearing block of last horizontal roller 1, can be used for adjusting the position of roll, and then realize that the collars position of horizontal roller 1,2 is adjusted up and down with respect to bearing block.Last horizontal roller 1 keeps its balance by last horizontal roller balanced controls 11.Last horizontal roller balanced controls 11 are fixed on the top of transmission side memorial archway 5, realize the upward balance of horizontal roller 1 by two bearing blocks that hydraulic cylinder drive " shoulder pole formula " equalizer bar hooks.Two covers of last horizontal roller are depressed mechanism 20 and are installed in respectively on the crossbeam on fore side and the transmission side memorial archway 5,6, and single movement realizes going up the adjustment of horizontal roller 1 position.
Following horizontal roller 2 is motionless with respect to the position of bearing block; Two covers of following horizontal roller 2 press mechanism 21 and are installed in respectively on the crossbeam under fore side and the transmission side memorial archway 5,6, and single movement is realized the adjustment of horizontal roller 2 positions down.
As Fig. 1,2,3, shown in 4, the bearing of edger roll 3,4 is the circular cone roller bearing, and bearing places within the collars, and mandrel is fixed on the edger roll case, and the roll-force of edger roll is by the edger roll case, and edger roll screw-down 16,18 reaches transmission side and the horizontal yoke 7,8 of fore side.Depressing of each edger roll 3,4 adopts a fluid motor-driven two cover worm gear-screw pair mechanisms to realize that screw pair places among the horizontal yoke 7,8.The balance of each edger roll by one place among the horizontal yoke, hydraulic cylinder between two side pressure screw pairs finishes.
Transmission side and fore side memorial archway 5,6 are installed on the rail chair 14, and it is bolted to connection with transmission side and the horizontal yoke 7,8 of fore side respectively.Respectively have four through holes on the column of fore side and transmission side memorial archway 5,6, four memorial archway cylinder lever connecting rods 9 stretch into wherein respectively, and fixedly connected with transmission side memorial archway 5.It is fastening by hydraulic nut 10 that memorial archway cylinder lever connecting rod 9 passes an end of fore side memorial archway 6, and have certain pretightning force, thereby two memorial archways are linked together securely, and the rigidity of milling train on edger roll rolling direction is guaranteed.
Present embodiment is done following improvement on the basis of above-mentioned prior art:
As shown in Figure 1, one guide and guards 24, it is installed in up and down, and the plain-barreled roll roller is 1, on 2, guide and guards 24 also obtains adjusting thereupon when carrying out the roll gap adjustment, the i.e. up and down opening degree of guide and guard servo-actuated along with the roll gap adjustment of horizontal roller 1,2 up and down in the operation of rolling, guide and guards 24 is changed with roller system during roll change.The roller replacing operation time is shortened in dismounting on line, and can the be online outer adjustment of carrying out guide and guard.
As Fig. 1, shown in 5, also comprise a roll change buggy 12, this roll change buggy 12 comprises car body, wheel and eight backstays (each four of fore side and transmission sides), wheel rail is divided into machine inner orbit 25 and machine outside track 26, and machine outside track 26 maintains static, and machine inner orbit 25 is by the Driven by Hydraulic Cylinder liftable.During steel rolling roll change buggy 12 at random inner orbit 25 drop to low level, bottom roll bearing block and dolly break away to be sitting in and press on the screw.Roll change buggy 12 is raised up to the roll change position during roll change, four backstays on the dolly 12 pass down two bearing blocks of horizontal roller 2 respectively, and with its location, this moment, the top of eight backstays then withstood in the groove of bottom of edger roll case (four detents are arranged at each edger roll case bottom).The bottom surface of last horizontal roller 1 bearing block has the location to cooperate with the end face of edger roll case, so up and down the plain-barreled roll roller be 1,2 and the edger roll roller be 3,4 all to place on the roll change buggy 12, and be positioned to as a whole, can move horizontally along the roll axis direction at rail chair 14, can realize the integral replacing of roller system when making roll change, shorten the time of roller replacing operation.
As Fig. 3, shown in 4, a roll change travelling platform 15 is arranged at rail chair 14 stage casings, and it can be along moving horizontally perpendicular to the roll axis direction; The station that is provided with before and after roll change travelling platform 15 has two, one is used to place the roller of changing, and another is used to place the roller of changing.
As Fig. 1,2,3, shown in 4, a roll change drive unit 13 comprises a hydraulic cylinder, the axis normal of hydraulic cylinder is used to drive roll change buggy 12 and operation survey memorial archway in rolling line.The cylinder head of hydraulic cylinder and cylinder tail respectively have a ram 131,132, and ram 131,132 can slide on rail chair 14, and ram 131 is fixedlyed connected with fore side memorial archway 6, and fore side memorial archway 6 and roll change buggy 12 are connected by bearing pin.
As Fig. 1, shown in 2, transmission side memorial archway 5 normally is fixed on the rail chair 14, and fore side memorial archway 6 is fixedlyed connected with ram 131, under the drive of roll change drive unit 13, can move, realize separating of transmission side and fore side memorial archway with closed in rail chair 14 upper edge roll axis directions.Have fixedly shifting block on the rail chair 14, ram 132 is provided with the adjustable tumbler pusher dog of direction, and the toppling direction of tumbler pusher dog is different when separating with closed memorial archway, can both block shifting block on the rail chair 14 with the tumbler pusher dog on the assurance ram 132.
Also be provided with four positioning sleeves 23 between transmission side memorial archway 5 and the fore side memorial archway 6, be contained in respectively on four memorial archway cylinder lever connecting rods 9, when memorial archway was closed, two end faces of positioning sleeve 23 support respectively at the inboard of two memorial archways and with this guaranteed the centre-to-centre spacing of two memorial archways.
Because transmission side memorial archway 5 and fore side memorial archway 6 can separate when roll change, flat edger roll is to pass in and out from the window of fore side memorial archway 6, as long as the width of memorial archway window is suitable for the width of roll chock like this, under the identical prerequisite of dimension of roller, the memorial archway of present embodiment is much smaller than the common memorial archway of driving yoke formula universal mill.
