Abstract
The utility model relates to a convexity adjustment deivce of a twenty-high rolling mill. The convexity adjustment deivce comprises a B roll mandrel, a C roll mandrel and backing bearings and is characterized in that inner eccentric rings, outer eccentric rings and saddle rings are respectively sleeved on the B roll mandrel and the C roll mandrel sequentially from inside to outside. Needle rolling bearings are respectively arranged between the inner eccentric rings and the outer eccentric rings and between the outer eccentric rings and the saddle rings, and eccentric saddles are arranged on the saddle rings. Sector gear sheets are connected onto the outer eccentric rings of the B roll mandrel and the C roll mandrel, a hydraulic oil cylinder is arranged on the vertical intersecting line of the symmetrical centerlines of the B roll mandrel and the C roll mandrel, a two-sided rack meshed with the sector gear sheets connected onto the outer eccentric rings of the B roll mandrel and the C roll mandrel is arranged at the end of a hydraulic rod of the hydraulic oil cylinder, and a displacement sensor is arranged on the hydraulic oil cylinder. The convexity adjustment deivce has the advantages that eccentricity of the eccentric rings is large, a B roll and a C roll are double-eccentric, and a hydraulic system is fast in response, short in check time and high in sensitivity.
Description
Technical field
The utility model relates to a kind of convexity adjusting apparatus of mill, belongs to the steel rolling equipment field.
Background technology
1-2-3-4 type symmetric arrangement (as shown in Figure 1) is up and down pressed by the roller system of mill, two working rolls are supported on respectively on two first intermediate rolls up and down, the latter is supported on again on 3 second intermediate rolls, and second intermediate rolls is supported on again on outermost 4 backing rolls.Usually be live-roller with 4 rollers in the second intermediate rolls outside, each roller adopts English alphabet A～T to indicate in proper order in the roller system.The convexity guiding mechanism all need be joined by the roller of mill system, and older convexity guiding mechanism is adjusted position at each and one cover hydraulic motor, worm-gear speed reducer are installed are driven two-sided tooth bar and move up and down and adjust roll shape.This hydraulic radial roll shape guiding mechanism adopts button and mechanical indicator to adjust, and the commanded response speed of system is slower, and correction time is longer, and sensitivity is lower, is difficult to satisfy present production operation quality.And the axial convexity guiding mechanism of morning can not be adjusted in the operation of rolling, can only adjust in advance before rolling.
Summary of the invention
The purpose of this utility model provides a kind of by regulating the axis shape of B, C roller, realize the function that the mill convexity is regulated, thereby better control the template of band, can obtain the convexity guiding mechanism of mill of the band of straight template and broad ways consistency of thickness.
The purpose of this utility model realizes in the following manner:
The utility model comprises B roll centre axle, C roll centre axle and be sleeved on B roll centre axle and C roll centre axle on back lining bearing, it is characterized in that: on B roll centre axle and C roll centre axle, be with interior eccentric hoop from inside to outside successively, outer eccentric hoop, the saddle ring, interior eccentric hoop and outside between the eccentric hoop, between outer eccentric hoop and the saddle ring needle bearing is housed, be provided with eccentric saddle at the saddle ring, outer eccentric hoop at B roll centre axle and C roll centre axle is connected with the sector gear sheet, be provided with hydraulic jack with the line that intersects vertically of B roll centre axle and C roll centre axial symmetry center line, the hydraulic pressure rod end of hydraulic jack is provided with simultaneously the two-sided tooth bar of the sector gear sheet engagement on the outer eccentric hoop with B roll centre axle and C roll centre axle, is provided with displacement transducer at hydraulic jack.
The utility model has the advantages that:
Strengthened the offset of eccentric hoop, B, C roller are two eccentric, outer eccentric hoop is connected with the sector gear sheet, realized that by double cog bar driven gear sheet outer eccentric hoop rotates, when the outer eccentric hoop corner (adjustment amount) of eccentric saddle not simultaneously, will change B, C roll axis shape, realize the radially function of convexity adjusting, and the hydraulic system response speed is fast, and proof time is short, and is highly sensitive.
Description of drawings
Fig. 1 is that the roller system of mill forms schematic diagram;
Fig. 2 is structural representation of the present utility model.
Among the figure: 1-interior eccentric hoop; 2-back lining bearing; 3-pin; 4-outer eccentric hoop; 5-needle bearing; 6-sector gear sheet; 7-C roll centre axle; 8-saddle ring; 9-two-sided tooth bar; 10-hydraulic jack; 11-displacement transducer; 12-eccentric saddle; 13-B roll centre axle.
The specific embodiment
With reference to accompanying drawing, the utility model comprise B roll centre axle 13, C roll centre axle 7 and be sleeved on B roll centre axle and C roll centre axle on back lining bearing 2, mounted component is identical on B roll centre axle 13 and the C roll centre axle 7, eccentric hoop 1, outer eccentric hoop 4, saddle ring 8 on B roll centre axle and C roll centre axle, being with successively from inside to outside, interior eccentric hoop and outside between the eccentric hoop, between outer eccentric hoop and the saddle ring needle bearing 5 is housed, can reduce pivoting friction; Be provided with eccentric saddle 12 at the saddle ring, outer eccentric hoop at B roll centre axle and C roll centre axle is connected with sector gear sheet 6 with pin 3, be provided with hydraulic jack 10 with the line that intersects vertically of B roll centre axle and C roll centre axial symmetry center line, the hydraulic pressure rod end of hydraulic jack is provided with simultaneously the two-sided tooth bar 9 of the sector gear sheet engagement on the outer eccentric hoop with B roll centre axle and C roll centre axle, is provided with displacement transducer 11 at hydraulic jack.Hydraulic cylinder drives two-sided tooth bar and the engagement of sector gear sheet, forms radially convexity guiding mechanism.
Its principle is:
The convexity adjustment drives two-sided tooth bar by hydraulic jack and moves up or down, and the sector gear sheet that two-sided tooth bar drives on B, the C roller simultaneously rotates, and the sector gear sheet is fixed on the outer eccentric hoop by pin, thereby the outer eccentric hoop of outermost layer backing roll B, C is rotated.Because outer eccentric hoop and frame semicircle orifice are eccentric, therefore elastic bending deflection takes place in a certain position on the backing roll axle, thereby the corresponding back lining bearing position of backing roll is changed, just can make the alteration of form of working roll appropriate section by intermediate calender rolls, reach the purpose that convexity is adjusted.Because the frictional resistance of the outer eccentric hoop of the inside and outside needle bearing that all is equipped with of eccentric hoop, so rotation outside is very little, so fine adjustment flexibly can be done by this mechanism in the operation of rolling.Outer eccentric hoop offset can reach 2mm, and the convexity amount of eccentric saddle is that the offset of B, C spring bearing can reach 0～720 μ m, has improved the template control ability.Owing to can carry out independent or several adjustment simultaneously to each back lining bearing, therefore can obtain the required various roll shapes of rolling mill practice.
