Abstract

The utility model relates to a cleaner for rolling the roller surface in steel plate rolling process, in particular to a non-contact roller face electromagnetic cleaner. A working roll is installed on a bearing seat. The utility model is characterized in that the electromagnetic cleaner comprises an electromagnet, a spring, a screw bolt and a nut. The electromagnet is in long shape. Each of the two ends of the electromagnet has a shoulder which is provided with a screw hole. The bearing seat is provided with a screw bolt which is coated by a spring. The two ends of the spring are connected with the bearing seat and the shoulders at the ends of the electromagnet. The screw bolt traveling through the shoulder is wrenched by the nut. An air gap exists between the electromagnet and the working roll. The air gap between the electromagnet and the working roll can be adjusted by a swiveling nut. Compared with prior art, the utility model has the advantages of simple structure, small volume, convenient operating and good effect on cleaning the iron dust on the roller surface of the roll.

Description

Contactless roll surface electromagnetism cleaner

(1) technical field

The utility model relates to the cleaning device of roll roll surface in the steel plate rolling process.

(2) background technology

Along with the continuous development of industries such as automobile and household electrical appliances, more and more high to the requirement of cold rolling textured steel sheet, original BST shot-peening texturing roller that adopts has not satisfied the demand in this market.Adopting more roller texturing method both at home and abroad at present is electric cremate texturing, i.e. EDT roll surface texturing technology.Though the textured steel sheet quality that adopts EDT electricity cremate roll surface texturing technology to produce obviously is better than shot-peening roll surface texturing technology, but, steel plate is in the operation of rolling, because the cleannes of milling train self, the difficult control of emulsion cleannes, coming off and being difficult to of rolled steel edges of boards portion burr removed immediately, especially the roll of EDT texturing is than the easier adhesiving metal impurity particle of its roll surface roughness peak of profile of shot-peening texturing, so after passing through milling train, because rolling effect, iron filings can be sticked on the roller surfaces firmly, caused the periodicity of surface of cold-rolled steel plate defective to occur, influence the production of the cold rolling textured steel sheet of high-quality, hindered EDT electricity cremate roll surface texturing The Application of Technology.Existing roll roll surface cleaning device generally all is to adopt contact, as " roll cleaning device " (China Patent No. 94114987) and " the milled sheet continuous cleaning and the lubricating arrangement of rolling mill roll " (China Patent No. 85105838), directly contact removal of contamination, but have easily the defective of damaging roll surface, not cleaning up with the roll roll surface.

(3) summary of the invention

The utility model has overcome the defective of existing contact roll roll surface cleaning device, and a kind of contactless roll surface electromagnetism cleaner is provided.This roll surface electromagnetism cleaner adopts contactless electromagnet structure, and the adjustable gaps of electromagnet and working roll is simple in structure, volume is little, and is easy to operate, and removing roll roll surface iron filings are effective.

The utility model is achieved in that a kind of contactless roll surface electromagnetism cleaner, comprise electromagnet, spring, bolt, nut, working roll is installed on the bearing block, it is characterized in that electromagnet is a strip, there is a convex shoulder at the electromagnet both ends, have screw on the convex shoulder, bolt is housed on the bearing block, spring housing is contained on the bolt, both ends of the spring connecting axle bearing and electromagnet end convex shoulder, the bolt that passes convex shoulder is by nut screwing clamping, and making between electromagnet and working roll has air gap, but the size of rotation nut regulating magnet and working roll air gap.

Above-mentioned contactless roll surface electromagnetism cleaner, described electromagnet is an arc surface in the face of the face of working roll; The external demagnetization connector lug that fills of electromagnet fills the demagnetization connector lug and connects the portable demagnetization power supply that fills.

Operation principle of the present utility model is that this roll surface electromagnetism cleaner adopts contactless electromagnet structure, the adjustable gaps of electromagnet and working roll, and electromagnet loads and unloads and clears up conveniently for filling the permanent-magnet material of demagnetization continuously.Can make roller surface cleaning, smooth, avoid producing Surface Defects in Steel Plate because of being involved in of iron filings.The utility model compared with prior art, and is simple in structure, volume is little, and is easy to operate, and it is effective to remove roll roll surface iron filings.

(5) specific embodiment

Provide embodiment of the present utility model below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of contactless roll surface electromagnetism cleaner comprises electromagnet 2, spring 5, bolt 4, nut 7.Working roll 1 is installed on the bearing block 6.Electromagnet 2 is the strip permanent-magnet material, and electromagnet 2 is in the face of the face of working roll 1 is an arc surface, makes that the working gas gap 3 of 1 of electromagnet 2 and working roll is even; There is a convex shoulder at electromagnet 2 both ends, have screw on the convex shoulder.Bolt 4 is housed on the bearing block 6, spring 5 is sleeved on the bolt 4, spring 5 two ends connecting axle bearings 6 and electromagnet 2 end convex shoulders, passing the bolt 4 of convex shoulder is tightened by nut 7, but the size of rotation nut 7 regulating magnets 2 and working roll 1 air gap 3, can in the 2-50mm scope, set air gap 3 positions arbitrarily, remove 1 iron filings of working roll with optimum efficiency.The electromagnet 2 external demagnetization connector lugs 10 that fill fill demagnetization connector lug 10 and connect the portable demagnetization power supply that fills, and electromagnet 2 makes loading and unloading and clears up more convenient for can fill the permanent-magnet material of demagnetization continuously like this.

Referring to Fig. 1, band steel 8 is in through working roll 1 cold rolling texturing process, a pair of electromagnet 2 absorption that the iron filings that cooling fluid or strip edge portion burr are brought into can be set at before working roll 1 is involved in the other contactless roll surface electromagnetism cleaner of two rollers are removed, and can avoid the Surface Defects in Steel Plate that causes because of being involved in of iron filings.
