Description

A kind of combined oil removing device

Technical field

The utility model relates to the cold-rolling mill technical group field, is specifically related to a kind of combined oil removing device.

Background technology

In cold rolling unit in order to improve rolling mill speed and stability, reduce roll torque, reduce roller surface humidity, different materials is adopted different technological lubrication liquid, and this is the needs of rolling mill practice, but must remove the residual lubricating fluid of strip surface clean in the finished product volume, otherwise, easily produce when take-up sliding band, the residue of technological lubrication liquid will pollute strip surface after the annealing, affect product quality.Therefore, whether normally the quality of deoiling effect directly has influence on milling train production and product quality.For this reason before the machine of milling train, behind the machine (reversable mill) degreasing unit must be set, general roll oil-removing apparatus is the roll-type oil removing, and perhaps independent air knife purges, and deoiling effect is poor, the residual lubricated liquid measure of strip surface is large, is difficult to reach the quality requirement of High Precision Cold product.

Summary of the invention

In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of combined oil removing device, and performance safety is reliable, online oil removing.

In order to achieve the above object, the technical scheme taked of the utility model is:

A kind of combined oil removing device comprises that five roller degreasing units, three roller oil squeezing devices and base 13, five roller degreasing units and three roller oil squeezing devices are installed on the base 13.

Five roller degreasing units comprise that the first rack-and-pinion lazy-tongs 1, the first rack-and-pinion lazy-tongs 1 are installed in the five roll oil-removing apparatus frames 3, and front-seat air knife 2 is installed in the front portion of five roll oil-removing apparatus frames 3; Upper except oiling roller 4 be installed in the five roll oil-removing apparatus frames 3 except the bearing block of oiling roller 5 by separately down, driving lower the first hoist cylinder 6 except oiling roller is connected with lower bearing block except oiling roller 5, the first rack-and-pinion lazy-tongs 1 are by gear and the lower tooth bar engagement that removes on the oiling roller 5 two end axles bearings, and final vacuum cutter 7 is installed in the rear portion of five roll oil-removing apparatus frames 3.

Three roller oil squeezing devices comprise that pony roll directly squeezes oiling roller 10, pony roll directly squeezes oiling roller 10 and two backing rolls 9 bearing by separately and is fixed on the bearing block, bearing block is fixed on 8 li of three roller oil squeezing device frames, the second rack-and-pinion lazy-tongs 11 are installed in the three roller oil squeezing device frames 8, the second hoist cylinder 12 that drives lower crowded oiling roller is connected with the bearing block of backing roll 9, and the second rack-and-pinion lazy-tongs 11 mesh by the tooth bar on gear and the lower backing roll 9 two end axles bearings.

The beneficial effects of the utility model are: this combined oil removing device has that performance safety is reliable, and deoiling effect is effective, can be used for the cold rolling unit of different materials, different-thickness strip, and the strip surface resid amount can reach more satisfactory effect after the oil removing.

Description of drawings

Accompanying drawing is structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail.

With reference to accompanying drawing, a kind of combined oil removing device comprises that five roller degreasing units, three roller oil squeezing devices and base 13, five roller degreasing units and three roller oil squeezing devices are installed on the base 13.

Five roller degreasing units comprise that the first rack-and-pinion lazy-tongs 1, the first rack-and-pinion lazy-tongs 1 are installed in the five roll oil-removing apparatus frames 3, and front-seat air knife 2 is installed in the front portion of five roll oil-removing apparatus frames 3; Upper except oiling roller 4 be installed in the five roll oil-removing apparatus frames 3 except the bearing block of oiling roller 5 by separately down, drive lower the first hoist cylinder 6 except oiling roller and be connected with the lower bearing block that removes oiling roller 5, final vacuum cutter 7 is installed in the rear portion of five roll oil-removing apparatus frames 3.

Three roller oil squeezing devices comprise that pony roll directly squeezes oiling roller 10, pony roll directly squeezes oiling roller 10 and two backing rolls 9 bearing by separately and is fixed on the bearing block, bearing block is fixed on 8 li of three roller oil squeezing device frames, the second rack-and-pinion lazy-tongs 11 are installed in the three roller oil squeezing device frames 8, and the second hoist cylinder 12 that drives lower crowded oiling roller is connected with the bearing block of backing roll 9.

Operation principle of the present utility model is:

Front-seat air knife 2 blow devices in five roll oil-removing apparatus, compressed air is entered the air knife high pressure chest through air inlet, air-flow just forms the high pressure draught thin slice of an equilibrium at front-seat air knife 2 length directions after by narrow, thin thin nozzle, first most of residual emulsion and the ROLLING OIL of strip surface is purged.Then band is through five roller degreasing units, drive its lifting except oiling roller 5 by the first hoist cylinder 6 down, the first rack-and-pinion lazy-tongs 1 are by gear and the lower tooth bar engagement that removes on the oiling roller 5 two end axles bearings, synchronous except oiling roller 5 two ends liftings under guaranteeing, press simultaneously during work, force band removing oiling roller 4 and lower flexural deformation except producing the type of falling W between the oiling roller 5, the large I of deflection is adjusted according to the band of different materials, different-thickness, to realize best deoiling effect.Then band blows remaining emulsion and ROLLING OIL off by final vacuum cutter 7 blow devices at frame rear portion again.

Last band is again through squeezing the oiling roller device, pony roll directly squeezes oiling roller 10 and two backing rolls 9 bearing by separately and is fixed on the bearing block, four backing rolls adopt segmentation to support, back lining bearing is installed, prevents that with this pony roll from directly squeezing pony roll footpath large flexural deformation of generation in the oil removing process of oiling roller 10.Lower backing roll 9 drives its lifting by the second hoist cylinder 12, the second rack-and-pinion lazy-tongs 11 mesh by the tooth bar on gear and the lower backing roll 9 two end axles bearings, press simultaneously when guaranteeing the work of lower backing roll 9 two ends, guarantee that pony roll directly squeezes oiling roller 10 and fully contacts with band, remove the last one deck oil film that is attached to strip surface with this.
