Description

A kind of degreasing unit

Technical field

The present invention relates to the cold-rolling mill technical group field, be specifically related to a kind of degreasing unit.

Background technology

In cold rolling unit,, reduce roll torque, reduce roller surface humidity in order to improve rolling mill speed and stability; Different materials is adopted the different processes lubricating fluid, and this is the needs of rolling mill practice, but in the finished product volume, must remove the residual lubricating fluid of strip surface clean; Otherwise; Be prone to produce sliding band when take-up, the residue of annealing back technological lubrication liquid will pollute strip surface, influence product quality.Therefore, the quality of deoiling effect directly has influence on milling train whether ordinary 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-type degreasing unit 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 big, is difficult to reach the quality requirement of high accuracy cold-rolled products.

Summary of the invention

In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of degreasing unit, performance is safe and reliable, online oil removing.

In order to achieve the above object, the technical scheme taked of the present invention is:

A kind of degreasing unit 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-type degreasing unit frames 3, and front-seat air knife 2 is installed in the front portion of five roll-type degreasing unit frames 3; Go up to remove oiling roller 4 and remove the bearing block of oiling roller 5 through separately down and be installed in the five roll-type degreasing unit frames 3; Driving first hoist cylinder 6 that removes oiling roller down is connected with the bearing block that removes oiling roller 5 down; The first rack-and-pinion lazy-tongs 1 are through gear and the tooth bar engagement that removes down on the oiling roller 5 two end axles bearings, and final vacuum cutter 7 is installed in the rear portion of five roll-type degreasing unit 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 and passes through separately bearing fixing on 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 second hoist cylinder 12 of crowded oiling roller is connected with the bearing block of backing roll 9 under driving, and the second rack-and-pinion lazy-tongs 11 are through the engagement of the tooth bar on gear and the following backing roll 9 two end axles bearings.

Beneficial effect of the present invention is: it is safe and reliable that this combined oil removing device has performance, 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 a structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is done detailed description.

With reference to accompanying drawing, a kind of degreasing unit 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-type degreasing unit frames 3, and front-seat air knife 2 is installed in the front portion of five roll-type degreasing unit frames 3; Go up to remove oiling roller 4 and remove the bearing block of oiling roller 5 through separately down and be installed in the five roll-type degreasing unit frames 3, drive first hoist cylinder 6 that removes oiling roller down and be connected except that the bearing block of oiling roller 5 down, final vacuum cutter 7 is installed in the rear portion of five roll-type degreasing unit 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 and passes through separately bearing fixing on 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 driving down, second hoist cylinder 12 of crowded oiling roller is connected with the bearing block of backing roll 9.

Operation principle of the present invention is:

Front-seat air knife 2 blow devices in the five roll-type degreasing units; Compressed air is got into the air knife high pressure chest through air inlet; Air communication is narrow excessively, just form the high pressure draught thin slice of an equilibrium behind the thin thin nozzle at front-seat air knife 2 length directions, earlier most of residual emulsion and the ROLLING OIL of strip surface purged.Band is through five roller degreasing units then; Remove oiling roller 5 down and drive its up-down through first hoist cylinder 6, the first rack-and-pinion lazy-tongs 1 mesh through gear and the tooth bar that removes down on the oiling roller 5 two end axles bearings, guarantee to remove down oiling roller 5 two ends and go up and down synchronous; Press simultaneously during work; Force band to remove oiling roller 4 and remove the flexural deformation that produces the type of falling W between the oiling roller 5 down last, the big I of deflection is adjusted according to the band of different materials, different-thickness, to realize best deoiling effect.Band blows remaining emulsion and ROLLING OIL off through final vacuum cutter 7 blow devices at frame rear portion more then.

Last band is again through squeezing the oiling roller device; Pony roll directly squeezes oiling roller 10 and two backing rolls 9 and passes through separately bearing fixing on 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 big flexural deformation of generation in the oil removing process of oiling roller 10.Following backing roll 9 drives its up-down through second hoist cylinder 12; The second rack-and-pinion lazy-tongs 11 are through the engagement of the tooth bar on gear and the following backing roll 9 two end axles bearings; Press simultaneously when guaranteeing backing roll 9 two ends work down; Guarantee that pony roll directly squeezes oiling roller 10 and fully contacts with band, remove last one deck oil film attached to strip surface with this.
