The utility model has few moving secondary links, reliable use and convenient maintenance; hydraulic operation is adopted, so that the response is quick and the sensitivity is high; and the adjusting precision of the rolling line of the rolling mill is high and the quality of rolled pieces can be effectively ensured.
Description
Technical field
The utility model relates to a kind of stepless adjusting apparatus of rolling mill roll line, the roll line stepless adjusting apparatus that especially uses on the band and strip rolling mill.
Background technology
Milling train in use, roll constantly wearing and tearing diminishes, thereby causes that the roll line between the upper working rolls and lower working rolls changes, and influence drive control precision, rolled piece quality, serious possibly can't be finished rolling work.At present, the roll line adjusting device that milling train uses generally adopts motor reducer or hydraulic motor to be used as power, and drives screw mandrel by the trapezoidal thread secondary motion, the purpose that the wedge plate relatively moves about reaching.This traditional roll line adjusting device, complex structure, manufacturing cost height; The trapezoidal thread pair is out of order easily, and difficult in maintenance; The adjustment link is more, and mechanical clearance is difficult to eliminate fully, thereby it is low to adjust precision.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of stepless adjusting apparatus of rolling mill roll line is provided, and the kinematic pair link is few, uses reliably easy to maintenance; Hydraulic operation is finished, and response speed is fast, highly sensitive; The adjustment precision height of rolling mill roll line can effectively guarantee the rolled piece quality.
According to the technical scheme that the utility model provides, stepless adjusting apparatus of rolling mill roll line adopts goes up the bottom that wedge is connected lower support roller group, and backing plate is installed on the window base plane of framework memorial archway, and following wedge places on the backing plate; Hydraulic jack is connected with following wedge by Connection Block, and hydraulic jack is installed on the cylinder pedestal, and mangneto formula displacement transducer is built in the afterbody of hydraulic jack; Wedge moved under hydraulic jack drove, by the inclined-plane relative motion of upper and lower wedge.
The described upward wedge and the inclined-plane of following wedge and the angle of horizontal plane are between 4 °～8 °.
Described upward wedge, following wedge, backing plate all adopt 42CrMo superior alloy steel material to make.
Described mangneto formula displacement transducer can place the hydraulic jack outer surface.
Described cylinder pedestal is installed on ground or the steel platform.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; The kinematic pair link is few, uses reliably easy to maintenance; Hydraulic operation is finished, and response speed is fast, highly sensitive; The adjustment precision height of rolling mill roll line effectively guarantees the rolled piece quality.
Description of drawings
Fig. 1 is the scheme of installation of roll line stepless adjusting apparatus.
Fig. 2 is the structural representation of roll line stepless adjusting apparatus.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 2, comprise framework memorial archway 1, lower support roller group 2, roll line stepless adjusting apparatus 3, positioning guide rail 4, go up wedge 5, wedge 6, backing plate 7, Connection Block 8, hydraulic jack 9, cylinder pedestal 10 and mangneto formula displacement transducer 11 etc. down.
Among Fig. 1, roll line stepless adjusting apparatus 3 is located on the window base plane of framework memorial archway 1, and positioning guide rail 4 is installed in the both sides of roll line stepless adjusting apparatus 3, guarantees that wedge 6 shift positions are correct down.Roll line stepless adjusting apparatus 3 comprises wedge group, driving mechanism, positioning guide rail, detecting element.
Described wedge group is made of last wedge 5, following wedge 6, backing plate 7, and last wedge 5 is connected the bottom of lower support roller group 2, and backing plate 7 is fixed on the base plane of framework memorial archway 1 window, and following wedge 6 places on the backing plate 7.Last wedge 5, following wedge 6, backing plate 7 all adopt the 42CrMo superior alloy steel to make, their the surperficial via nitride that is in contact with one another is handled, has very high intensity and hardness, effectively delay the wearing and tearing of cammed surface, improved the allowable stress of contact, when guaranteeing that roll line is adjusted precision, prolonged the service life of wedge.
Among Fig. 2, the described upward wedge 5 and the inclined-plane of following wedge 6 and the angle of horizontal plane are 5 °, and backing roll group 2 is subjected to the time spent of doing of big roll-force instantly, and the inclined-plane that is in contact with one another of two wedges has auto-lock function, guarantee that lower support roller group 2 can not produce additional axial force when rolling, safe and reliable.
Described driving mechanism is a hydraulic jack 9, and hydraulic jack 9 is installed on the cylinder pedestal 10, and cylinder pedestal 10 is installed on the ground.Hydraulic jack 9 is connected with following wedge 6 by Connection Block 8, and mangneto formula displacement transducer 11 is built in the afterbody of hydraulic jack 9, by detecting the amount of movement of hydraulic cylinder piston rod, determines the lifting distance of lower support roller group 2.Wedge 6 moved under hydraulic jack 9 drove, and by the inclined-plane relative motion of upper and lower wedge, reached the purpose of stepless lifting lower support roller group 2, simultaneously by the detection of dynamic of mangneto formula displacement transducer 11, guaranteed the accurate adjustment position of roll line.
