Abstract
The invention discloses a rolling mill entrance band steel aligning and compressing device, wherein an upper guide plate frame is driven to move up and down to compress or release the band steels by an upper hydraulic cylinder. The band steels are aligned through a horizontal hydraulic cylinder which is mounted in a lower guide plate frame, wherein each of the lower guide plate frames at the work side and the transmission side is connected with a pull type displacement sensor; the lower guide plate frames at the work side and the transmission side move synchronously through a hydraulic servo system. The rolling mill entrance band steel aligning and compressing device is mounted at the entrance of a rolling mill stand and is used for aligning the central lines of the band steels to enter the rolling mill to the central line of rolling, so that the band steel are aligned; the band steels are compressed when the rolling mill stops running or an abnormal condition is occurred. The rolling mill entrance band steel aligning and compressing device changes the design through of the prior rolling mill entrance band steel aligning and compressing device and combines the rolling mill entrance aligning device and the band steel compressing device, and accordingly the space shortage at the entrance section of the rolling mill is relieved, the manufacturing cost is lowered, and the market competitiveness of the machine set is increased.

Technical field
The present invention relates to a kind of inlet of rolling mill centering of strip steel hold down gag.
Background technology
At present, domestic self-developing design, the inlet of rolling mill centering of strip steel hold down gag of manufacturing are form arranged apart, two single devices that centralising device with steel and hold down gag are arranged before and after being.In the course of work to steel to neutralization compress by centralising device and hold down gag, carried out respectively, 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 to change the mentality of designing of inlet of rolling mill centering of strip steel hold down gag, alleviate inlet of rolling mill section space ' anxiety " phenomenon.
Summary of the invention
Object of the present invention is exactly to design a kind of centering of strip steel hold down gag that is arranged in inlet of rolling mill side.This device is abandoned in single chassis in the past design concept arranged apart before and after centralising device and hold down gag, and centering of strip steel device and hold down gag are united two into one, and is 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: above in the charging aperture of frame, be provided with hydraulic cylinder, 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 the young and vestibule that vertical section is isosceles trapezoid of collar extension imperial palace, in the top, rear end of rear portion-upper guide plate frame of this vestibule, is provided with press strip and below front end, is provided with guide roller.Slide plate is fixed under upper guide plate frame.Below charging aperture, both sides are also provided with side gripper shoe.Fore side bottom guide frame and transmission side bottom guide frame are connected between described two gripper shoes through two sliding bars.Fore side bottom guide frame is respectively equipped with in transmission side bottom guide frame the hydraulic cylinder that two volumes equate, two horizontal piston bars are fixed on side gripper shoe relatively.Lower support frame is fixed on the below, position, middle of fore side bottom guide frame and transmission side bottom guide frame.Two centering wheels are fixed on fore side bottom guide frame and the transmission side bottom guide frame top at close side plate place separately symmetrically.
Adopted the present invention of above technical scheme to change 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 ' anxiety " phenomenon; reduce manufacturing cost, increase the market competitiveness of this unit equipment.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The present invention mainly consists of upper hydraulic cylinder, upper guide plate frame, guide roller, fore side lower support frame, transmission side lower support frame, side gripper shoe etc.In utilization, hydraulic cylinder drives upper guide plate frame to move up and down, and realizes the compression with steel or release.Utilize horizontal hydraulic cylinder built-in in bottom guide frame to realize the centering with steel, wherein the bottom guide frame of fore side and transmission side is respectively connected with stay-supported type displacement sensor, by Hydrauservo System, realizes being synchronized with the movement of fore side and transmission side bottom guide frame.
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.Be fixed on positioning sleeve 02 in frame upper piston rod 01 flexible played to guide effect.
In Fig. 2, Fig. 5, M is feedstock direction.Charging aperture is that collar extension imperial palace is young and vestibule that vertical section is 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 being 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 is crossed steel.
When upper piston rod 01 stretches out, upper guide plate frame 04 declines, and the slide plate 06 that is 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 with steel.
Fore side bottom guide frame 09 can slide along the axial of two guide posts 11 with transmission side bottom guide frame 10, guide post 11 is fixed in side gripper shoe 14, and two centering wheels 08 are fixed on fore side bottom guide frame 09 and transmission side bottom guide frame 10 top at close side plate 14 places separately symmetrically.
Fore side bottom guide frame 09 is all processed with hydraulic cylinder with transmission side bottom guide frame 10 inside, and piston rod 12 is fixed in side gripper shoe 14.Oil-feed and the oil return of control operation side bottom guide frame 09 and transmission side bottom guide frame 10 built-in hydraulic cylinder rodless cavities, can make it along guide post 11 to rolling centerline, move or deviate from rolling centerline, when fore side bottom guide frame 09 and transmission side bottom guide frame 10 move to rolling centerline, can realize the centering to threading band steel.Be fixed on fore side bottom guide frame 09, with the lower support frame 13 of the below, position, middle of transmission side bottom guide frame 10, the motion of hydraulic cylinder cavity played to position-limiting action.
Fig. 3 expresses extreme position that upper guide plate depresses and the extreme position of bottom guide centering.
Fig. 4 represents is the extreme position that the extreme position that lifts of upper guide plate and bottom guide are opened.
Whole device is positioned at and rolls machine set frame entrance side, and the band steel center line that will enter milling train is alignd with rolling centerline, realizes centering of strip steel function; Holddown belt steel when shutting down or the operation of rolling occurs abnormal conditions, realizes band steel substrate hold-down function.
