A kind of surface oil removing device for high-speed reversible cold rolling strip
The utility model belongs to stainless steel band processing technique field, is particularly applied in and removes a kind of surface oil removing device for high-speed reversible cold rolling strip that strip surface remains various lubricating fluid.
In cold-strip process, degreasing unit is widely used in all kinds of cold mill complex, and band is after milling train, and surface can remain a certain amount of lubricating fluid, and the lubricating fluid residual when strip surface is too much, makes very easily to break away during band high-speed rolling, causes broken belt accidents caused; And can produce oil mark after strand-anneal(ing), reduce product quality, the impact especially caused when producing ultra-thin strip is particularly evident; Although existing pony roll footpath, the roll oil-removing apparatus of multi-point support, to a certain extent, overcome surface quality of strips defect, but complex structure, and maintenance difficulties is large, manufacturing cost is high, and owing to there is gap between strip side portion and roller, practical effect is not very good.
Summary of the invention
In order to overcome the deficiency in background technology, the utility model provides a kind of high speed reversible strip surface oil removal device for cold rolling mill, and structure is simple, and easy to maintenance, processing cost is low, and solves the undesirable problem of existing degreasing unit deoiling effect.
In order to realize described goal of the invention, the utility model adopts following technical scheme:
A kind of high speed reversible strip surface oil removal device for cold rolling mill, comprise support, the guide plate of oil removing base is installed, lower guide plate and upper guide plate are each passed through the guide rod correspondence being fixed on support both sides and arrange, lower guide plate, upper guide plate are equipped with sliding bearing and can slide up and down along guide rod, and being floated by Floatable supporting mechanism bottom hydraulic cylinder is arranged on support.
Described hydraulic cylinder is separately positioned on fore side and the transmission side of cold-rolling mill, hydraulic cylinder bearing is fixedly connected with guide plate, the cylinder body of hydraulic cylinder is fixedly connected with lower guide plate, corresponding lower guide plate, upper guide plate is provided with dovetail groove, and lower oil removing base and the upper oil pipe that removes are arranged on lower guide plate and upper guide plate respectively by dovetail groove.
Described oil removing base is provided with U-lag, down except oil rubber hose and the upper oil rubber hose that removes are arranged in the U-lag of lower oil removing base and upper oil removing base respectively, down except oil rubber hose and the upper uniform groove of outer surface except oil rubber hose, cross section is convex arc shape, and its inside is provided with small-bore cavity.
Described Floatable supporting mechanism is spring supporting seat, includes, nut, screw rod, spring, bolt, and spring housing is located on the screw rod below nut, by the position of bolt adjusting screw(rod)
Owing to adopting technical scheme as above, the utility model produces following good effect:
1, bottom driving hydraulic cylinder, Floatable supporting mechanism is provided with, when in degreasing unit, band passes through, support degree is changed by the nut above adjusting screw(rod), accurate control is upper and lower except oil rubber hose and the docile degree of band steel, uniform stressed, trackability is good, only needs less clamping force just can reach good deoiling effect, and obviously can increase the service life of sebific duct.
2, upper and lower except oil rubber hose be Special diameter 20mm sebific duct, wear-resistant, good springiness, the dark water conservancy diversion groove of the uniform 2mm of sebific duct outer surface, cross section is convex arc shape, and center arranges 4mm small-bore cavity, and therefore sebific duct not easily piles up impurity and dirt, not easily large scuffing is caused to steel strip surface, and change conveniently.
3, upper and lower oil removing base can overallly from the dovetail groove of upper and lower guide plate respectively be extracted out together with the upper and lower oil rubber hose that removes, easy to maintenance, low cost of manufacture.

Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention in the utility model is described in further detail:
Composition graphs 1, Fig. 2, the surface oil removing device for high-speed reversible cold rolling strip of the present embodiment comprises support 1, is fixed on the guide rod 8 of support both sides, is provided with the guide plate of oil removing base, and guide plate can be divided into guide plate 3 and lower guide plate 2, their corresponding settings; Lower guide plate 2 and upper guide plate 3 are each passed through guide rod 8; Because lower guide plate 2 and upper guide plate 3 corresponding guide rod 8 side are equipped with sliding bearing, can slide up and down under the driving of hydraulic cylinder 10 along guide rod 8, being floated by Floatable supporting mechanism bottom hydraulic cylinder is arranged on support 1.The hydraulic cylinder 10 driving guide plate to move up and down is set respectively at the fore side of high speed reversible cold-rolling mill and transmission side, hydraulic cylinder bearing 9 is fixedly connected with guide plate 3, the cylinder body of hydraulic cylinder 10 is fixedly connected with lower guide plate 2, when hydraulic cylinder 10 works, the corresponding guide plate arranged is together with oil removing base and be installed in oil removing base U-lag except the overall close to each other or separation along guide rod 8 of oil rubber hose; Oil removing base can be divided into lower oil removing base 4 and upper oil removing base 5 accordingly, except oil rubber hose can be divided into lower to oil rubber hose 6 and upper except oil rubber hose 7.
Composition graphs 3, Fig. 4, Fig. 5 oil removing base are provided with U-lag, except oil rubber hose 6 and the upper oil rubber hose 7 that removes are arranged in the U-lag of lower oil removing base 4 and upper oil removing base 5 respectively correspondingly, down except oil rubber hose 6, above except oil rubber hose 7 all adopts special except oil rubber hose, there is the advantages such as wear-resistant, good springiness.The upper and lower uniform water conservancy diversion groove of outer surface except oil rubber hose, cross section is convex arc shape, not easily accumulation impurity and dirt, and its inner cavity design adopting small-bore, is more convenient for embedding in the U-lag of oil removing base, and changes conveniently, namely replaceable online.
Composition graphs 6, Fig. 7, lower guide plate 2, the one side that upper guide plate 3 is relative is provided with dovetail groove, and lower oil removing base 4 and upper oil removing base 5 are firmly arranged on lower guide plate 2 and upper guide plate 3 respectively by dovetail groove, is convenient to overall extraction out, easy to maintenance.
Composition graphs 1, Fig. 2, Fig. 8, band is through after cold-rolling mill, first hydraulic cylinder 10 works, the guide plate that correspondence is arranged and the oil removing base installed successively, except oil rubber hose is overall close to each other along guide rod 8, make, down except oil rubber hose is resisted against band upper and lower surface with certain pressure, by the nut above regulating spring supporting seat 11 screw rod, support degree can be changed, in accurate control, down except oil rubber hose be close to after working face and unit roll line registration, on so just can effectively improving, down except oil rubber hose and steel band upper and lower surface uniform contact and stressed, improve the docile degree except oil rubber hose and steel band.Residual lubricating fluid unnecessary for strip surface is removed by the mode through contacting with band, extruding, thus effectively improves the deoiling effect producing ultra-thin strip product.
In sum, above description is preferred embodiment of the present utility model, certainly, is not limited to this.Namely every simple equivalence change done according to the utility model claim and description with modify, all should still belong in scope that the utility model patent contains.
