Description

Flexible roller surface wiping device

Technical Field

The utility model relates to a rolling mill technical field specifically is a flexible roll surface wiping arrangement.

Background

The plate rolling mill equipment is used for rolling a steel billet into a steel plate, and the lower working roll wiping device is used for cleaning the roll surface of a working roll, guiding away iron scales on the roll surface and ensuring the surface quality of the rolled steel plate. The original roller surface wiper is arranged at the lower part of the working roller, a spring is used as power, a wiping roller strip is tightly attached to the surface of the working roller by the spring force, and the roller surface of the working roller is wiped and cleaned by the close attachment. The following disadvantages exist in the design of the structure: the roll surface wiper is low in installation position, a groove is formed between the wiping roll strip and the water guide plate after installation, iron scales generated in the production process are easily accumulated in the groove, the accumulated iron scales are not easily washed away by water due to the small inclination angle of the water guide plate, the iron scales are adhered to a roll and are extruded to easily cause the pit defect on the roll surface, the bulge defect is generated on the surface of a steel plate during steel rolling, the surface quality of the steel plate is influenced, particularly the steel plate with high surface quality requirement is generated, the bulge defect or the pressed-in iron scales can be judged to be waste, and great economic loss is caused. Meanwhile, the defect of a pit on the surface of the lower roller can cause large grinding amount and low grinding efficiency of the roller, and the consumption cost of the roller is high.

Disclosure of Invention

The utility model aims at providing a flexible roller surface wiping arrangement in order to solve the problem that above-mentioned current roller surface wiping arrangement exists.

The utility model has the following concrete scheme: the utility model provides a flexible roll surface wiping arrangement, including the water deflector, a plurality of V-arrangement support is equipped with along length direction in the water deflector top, it is equipped with a position control device who is connected with the V-arrangement support to lie in every V-arrangement support below fixed on the water deflector, the V-arrangement support is last to be equipped with microscler through-hole with the water deflector contact one side, fastening bolt is used for the position of fixed V-arrangement support in the microscler through-hole, a microscler layer board that is equivalent with the roller length is equipped with to the upper end of all V-arrangement supports, a rubber skin is equipped with along the full length on the layer board, rubber skin.

Position adjusting device is equipped with the screw rod of a top contact V-arrangement support bottom including fixing the nut on the water guide board in the nut, makes the screw rod promote the V-arrangement support through rotatory screw rod.

Rubber skin is the rectangle, and the centre symmetry be equipped with two rows of through-holes, and bolt and nut are used for fixing rubber skin on microscler layer board in one of them row of through-hole is equipped with.

The contained angle of V-arrangement support is 110 ~ 150.

The working principle of the utility model is as follows: the position of the V-shaped support is adjusted through the position adjusting device, so that the top end of the rubber sheet is completely attached to the roller surface, and the iron oxide sheet is taken away from the roller surface when the roller works.

Compared with the prior art, the utility model has the following advantage: 1. the whole wear-resistant high-temperature-resistant rubber belt is adopted, so that gaps formed among sectional roller wiping strips can be effectively avoided, and the roller wiping rubber has certain flexibility, can be better attached to the roller surface of the roller with the existing roller shape, and has better wiping effect; 2. the inclination angle of the rubber sheet of the wiping roller is larger than that of the water guide plate, and the iron scale is easy to wash away by water, so that the iron scale is not easy to accumulate.
