Abstract

The utility model discloses a wiping roller mounted on a wiping device in a rolling machine and specifically relates to an oil-scraping roller. The oil-scraping roller is composed of an oil-scraping roller shaft and an oil-scraping roller body, wherein the surface of the oil-scraping roller body has a shape of convex drum; the convex value at the center of a longitudinal cross section along horizontal position of the oil-scraping roller body is the maximum; and the convex value extending to two sides along the central part is gradually reduced till the convex value of two end parts is zero. The oil-scraping roller has the beneficial effects of being simple in structure, convenient in operation, and enabling surface of the oil-scraping roller body and a strip material to be uniform.

Description

Scrape oiling roller

Technical field

The utility model relates to a kind of wiper rolls on the wiper in the milling train that is installed in, and specifically is a kind of oiling roller of scraping.

Background technology

Sendzimir mill can produce a large amount of emulsion and ROLLING OIL on the surface of band when rolled strip, if a large amount of emulsions and ROLLING OIL are brought into coiling machine in strip surface, sliding band, the volume accident of collapsing take place easily in the coiling process; In addition because the particularity that silicon steel is produced; Rolling next operation is heat treatment; Steel strip surface blackout when if the remaining ROLLING OIL of strip surface too much can cause heat treatment; Cause defective even waste product, so sendzimir mill all is equipped with strip wiper in the gateway, wiper can clean strip surface and make its cleaning.

At present, mostly the oiling roller of scraping that is used for wiper is plain-barreled roll.But plain-barreled roll is in actual production process, during the wiping strip surface, when frizing roll shaft two ends are under pressure; After making plain-barreled roll and band contacting, because stress is concentrated plain-barreled roll generation deformation; Middle part perk and two ends press down makes to produce very big gap between the frizing body of roll and the band, causes the frizing effect not good enough.

The utility model content

The technical problem that the utility model will solve be to provide a kind of simple in structure, easy to operate, can effectively solve stress and concentrate and to cause the frizing body of roll to contact the uneven oiling roller of scraping with strip surface.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of oiling roller of scraping, to form by the frizing roll shaft and the frizing body of roll, and said frizing body surface is the cydariform of evagination; The frizing body of roll is maximum along the convex value of the central part of the longitudinal cross-section of horizontal level, extend convex value along central part to both sides and diminish gradually, to the convex value of two ends be zero.

Preferably, draw through inventor's experimental verification, when the maximum convex value of the frizing body of roll was 0.325mm, it was best with the applying degree of strip surface in the course of the work to scrape oiling roller, and stress distribution is even, the middle part can perk and two ends do not have the slit; According to the maximum convex value of the frizing body of roll is 0.325mm, and frizing body of roll horizontal direction radius is 700mm, obtains frizing body of roll convex value curvilinear equation formula Y=0.325-0.325 * X ²/ 490000; Said X is that any is apart from the horizontal range of central part arbitrarily on the frizing body surface, and Y is the corresponding convex value of this point.

The beneficial effect of the utility model:

1, only should show frizing body surface convex value, simple in structure;

2, do not change original band wiping process, simple to operate;

3, the frizing body of roll and strip surface fit tightly in the utility model, and the stress value at applying position is evenly distributed.

The specific embodiment

The set accompanying drawing elaborates to the specific embodiment of the utility model below.

A kind of oiling roller of scraping as shown in Figure 1 is made up of the frizing roll shaft 1 and the frizing body of roll 2.The frizing body of roll 2 surfaces are the cydariform of evagination; The frizing body of roll 2 is maximum along the convex value of the central part 3 of the longitudinal cross-section of horizontal level, is 0.325 millimeter; Extend convex value along central part 3 to both sides and diminish gradually, to the convex value of two ends 4 be zero.The convex value of the frizing body of roll 2 satisfies equation Y=0.325-0.325 * X ²/ 490000; Wherein X is that any some horizontal range apart from central part 3 is gone up on the frizing body of roll 2 surfaces, and Y is the corresponding convex value of this point.

In actual production process, scrape the oiling roller two ends and be under pressure the frizing body of roll 2 is contacted with strip surface, when pressure reaches 50～65MPa; The strip surface and the frizing body of roll 2 fit tightly; Stress distribution is even, does not have the obvious stress concentrated area, and the effect of scraping oiling roller cleaning band material this moment is preferable.

The above only is the preferred embodiment of the utility model, is not the utility model structure is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
