Description
Technical field
The present invention relates to a kind of inlet of rolling mill centering of strip steel hold down gag.
Technical background
At present, domestic self-developing design, the inlet of rolling mill centering of strip steel hold down gag manufactured are form arranged apart, two single devices that the centralising device namely with steel and hold down gag are arranged before and after being.Performed by centralising device and hold down gag respectively compressing neutralization of band steel in the course of work, this design has tied up the limited space of inlet of rolling mill.When inlet of rolling mill overhaul of the equipments, this will bring inconvenience.This just requires the mentality of designing changing inlet of rolling mill centering of strip steel hold down gag, alleviate inlet of rolling mill section space ' nervous " phenomenon.
Summary of the invention
Object of the present invention is exactly to design a kind of centering of strip steel hold down gag being arranged in inlet of rolling mill side.This device abandon in the past in single chassis by design concept arranged apart before and after centralising device and hold down gag, centering of strip steel device and hold down gag are united two into one, are designed to a single devices.
For solving the problems of the technologies described above, the present invention proposes following technical scheme: a kind of inlet of rolling mill centering of strip steel hold down gag, it has following characteristics: be provided with hydraulic cylinder above in the charging aperture of frame, upper piston rod stretches out downwards through positioning sleeve, and the lower end of this upper piston rod is provided with ball head structure and is connected with upper guide plate frame.Charging aperture is that collar extension imperial palace is young and vertical section is the vestibule of isosceles trapezoid.Above the rear end of upper guide plate frame, be provided with press strip and be provided with guide roller below front end.Slide plate is fixed under upper guide plate frame.Collateral fagging is also provided with in the both sides, below of charging aperture.Fore side bottom guide frame and transmission side bottom guide frame are connected between described two collateral faggings through two sliding bars.Fore side bottom guide frame is respectively provided with the equal hydraulic cylinder of a volume respectively with in transmission side bottom guide frame, and two horizontal piston bars are fixed on collateral fagging relatively.Lower support frame is fixed on below the position, middle of fore side bottom guide frame and transmission side bottom guide frame.Two centerings wheel is fixed on the top at fore side bottom guide frame and transmission side bottom guide frame close collateral fagging place separately symmetrically.
The present invention that have employed above technical scheme changes the mentality of designing of inlet of rolling mill centering of strip steel hold down gag in the past, inlet of rolling mill centralising device and band steel hold down gag are united two into one, alleviate inlet of rolling mill section space ' nervous " phenomenon; reduce manufacturing cost, increase the market competitiveness of this unit equipment.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
The present invention is primarily of formations such as upper hydraulic cylinder, upper guide plate frame, guide roller, fore side lower support frame, transmission side lower support frame, collateral faggings.In utilization, hydraulic cylinder drives upper guide plate frame to move up and down, and realizes the compression to band steel or release.Utilize horizontal hydraulic cylinder built-in in bottom guide frame to realize the centering of band steel, wherein the bottom guide frame of fore side and transmission side is respectively connected with stay-supported type displacement sensor, realizes being synchronized with the movement of fore side and transmission side bottom guide frame by Hydrauservo System.
Upper hydraulic cylinder is that flange is fixed, is fixed on the top of frame 15 by ring flange.Upper piston rod 01 is connected with the spheric seat of upper guide plate frame 04 by bulb 03.Bulb mechanism is because being common mechanism, and the application does not illustrate.The flexible of positioning sleeve 02 pair of upper piston rod 01 be fixed in frame plays guide effect.
In Fig. 2, Fig. 5, M is feedstock direction.Charging aperture is that collar extension imperial palace is young and vertical section is the vestibule of isosceles trapezoid, is provided with guide roller 07 below the front end of this vestibule.
When upper piston rod 01 is retracted along positioning sleeve 02, it drives upper guide plate frame 04 to move upward.Press strip 05 on upper guide plate frame 04 afterbody is by the locating surface that is stuck in frame, as shown in phantom in Figure 2, and now liquid presses piston pole 01 is not retracted into limit position yet, along with upper piston rod 01 continues to retract, upper guide plate frame 04 tilts to upwarp, and plays guide plate effect when threading crosses steel.
When upper piston rod 01 stretches out, upper guide plate frame 04 declines, and the slide plate 06 being fixed on upper guide plate frame 04 compresses fore side bottom guide frame 09, transmission side bottom guide frame 10 and lower support frame 13, realizes the compression to band steel.
Fore side bottom guide frame 09 and transmission side bottom guide frame 10 can slide along the axis of two guide posts 11, guide post 11 is fixed on collateral fagging 14, and two centering wheels 08 are fixed on fore side bottom guide frame 09 with transmission side bottom guide frame 10 symmetrically separately near the top at collateral fagging 14 place.
Fore side bottom guide frame 09 and transmission side bottom guide frame 10 inside are all processed with hydraulic cylinder, and piston rod 12 is fixed on collateral fagging 14.The oil-feed of control operation side bottom guide frame 09 and transmission side bottom guide frame 10 Innerscoping cylinder rodless cavity and oil return, it can be made to move along guide post 11 to rolling centerline or deviate from rolling centerline, when fore side bottom guide frame 09 moves to rolling centerline with transmission side bottom guide frame 10, the centering to threading band steel can be realized.The motion of being fixed on the lower support frame 13 pairs of hydraulic cylinder cavitys below fore side bottom guide frame 09 and the position, middle of transmission side bottom guide frame 10 plays position-limiting action.
Fig. 3 indicates the extreme position of upper guide plate pressure and the extreme position of bottom guide centering.
What Fig. 4 represented is extreme position that upper guide plate lifts and the extreme position that bottom guide is opened.
Whole device is positioned at and rolls machine set frame entrance side, the band steel center line that will enter milling train is alignd with rolling centerline, realizes centering of strip steel function; The holddown belt steel when abnormal conditions appear in shutdown or the operation of rolling, realizes band steel substrate hold-down function.
