Description
Technical Field
The utility model relates to a steel rolling field, in particular to under bracing roller export cutting board device for finish rolling.
Background
Most hot rolling lines currently employ oil-water mixtures sprayed onto the rolls to extend the roll life and reduce power consumption. The existing lower supporting roller lubricating device has unsatisfactory lubricating effect.
The hot rolling strip steel rolling process uses a large amount of cooling water to reduce the temperature of the working rolls, and in order to prevent the cooling water from being retained on the surface of the strip steel, an inlet side and an outlet side of each finish rolling stand are provided with an upper lower water cutting plate and a lower water cutting plate, and the lower water cutting plates are used for guiding away most of finish rolling supporting rolls and roller cooling water of the working rolls from two sides. The existing water cutting plate has unsatisfactory water sealing effect.
Disclosure of Invention
The utility model aims to solve the technical problem that a lower support roll export cutting board device for finish rolling is provided, improves and seals the water effect, improves backing roll water-cooling homogeneity, reduces the lower support roll surface and remains the water yield, helps hot rolling oil to adsorb the backing roll surface.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a lower support roll export water cutting plate device for finish rolling, the water cutting plate device is fixed on the backing roll crossbeam, the on-line screen storage device comprises a base, the water cutting plate, water cutting plate clamp plate, spring advancing mechanism, base and backing roll crossbeam rigid coupling, centre gripping water cutting plate between base and the water cutting plate clamp plate, and by fastening bolt connection, arrange a plurality of rectangular holes on the water cutting plate, fastening bolt passes the rectangular hole of water cutting plate, be equipped with spring advancing mechanism on the base, the rear side and the spring advancing mechanism butt joint of water cutting plate, the front side of water cutting plate is equipped with the inclined plane top and leans on the roll surface of backing roll under.
The spring propelling mechanism comprises an arched spring strip which is fixed on the base through a pin.
The cross section of the water cutting plate is L-shaped.
The water cutting plate is made of a phenolic cloth plate.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses the spring advancing mechanism of cutting water board structure through cutting water board rear end continuously applies elasticity, and the laminating power between automatic moderate degree regulation cutting water board and backing roll surface realizes cutting water board and the seamless butt joint of backing roll surface, and the cutting water board remains the laminating state with the backing roll surface all the time. The water sealing effect is improved, the water cooling uniformity of the supporting roller is improved, the residual water quantity on the surface of the lower supporting roller is reduced, hot rolling oil is favorably adsorbed to the surface of the supporting roller, and the cooling and lubricating effect of the process is further improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the base and the water cutting plate.
Fig. 3 is a schematic structural view of a pressing plate of the water cutting plate.
In the figure: the device comprises a supporting roll beam 1, a base 2, a water cutting plate 3, a water cutting plate pressing plate 4, a spring propelling mechanism 5, a strip hole 6, an arched spring strip 7, a pin 8 and a fastening bolt 9.
Detailed Description
The following further describes the embodiments of the present invention with reference to the attached drawings:
referring to the figures 1-3, the lower supporting roller outlet water cutting plate device for finish rolling is fixed on a supporting roller beam 1 and comprises a base 2, a water cutting plate 3, a water cutting plate pressing plate 4 and a spring propelling mechanism 5, wherein the base 2 is fixedly connected with the supporting roller beam 1, and the cross section of the water cutting plate pressing plate 4 is L-shaped. The water cutting plate 3 is clamped between the base 2 and the water cutting plate pressing plate 4 and is connected by the fastening bolt 9, and the water cutting plate 3 is made of a phenolic cloth plate. A plurality of elongated holes 6 are arranged in the water cutting plate 3, and fastening bolts 9 are inserted through the elongated holes 6 of the water cutting plate 3.
The base 2 is provided with a spring propelling mechanism 5, the spring propelling mechanism 5 comprises an arched spring strip 7, and the arched spring strip 7 is fixed on the base 2 through a pin 8. The rear side of the water cutting plate 3 is connected with the bow-shaped spring strip 7 in a propping way, and the front side of the water cutting plate 3 is provided with an inclined plane which leans against the roller surface of the lower supporting roller.
The device prevents water on the water cutting plate from spraying to the surface below the surface of the supporting roller, so that hot rolling oil is favorably adsorbed to the surface of the supporting roller, and the process lubrication effect is improved; meanwhile, a water film is formed at the contact position of the water cutting plate and the roller surface of the supporting roller, so that the process cooling uniformity of the supporting roller is improved;
the device is followed the backing roll and is got off the machine down, makes things convenient for the off-line to dismantle the adjustment, does not occupy the unit rolling production time, and then improves production efficiency, reduces personnel's operation safety risk.
Above utility model, to the ordinary technical personnel in this technical field, can also be right without deviating from the principle of the utility model, these improve and decorate and also fall into the protection scope of the utility model claims. The above description is only the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the concept of the present invention within the technical scope disclosed in the present invention.
