Description

Surface cleaning device for plate and strip

technical field

The utility model relates to a cleaning device for the surface of a plate and strip, in particular to a cleaning device for the surface of a plate and strip with a roller center offset.

Background technique

In order to reduce the rolling torque and reduce the surface humidity of the rolls in the cold rolling mill, process lubricants must be used. However, the residual lubricating fluid on the surface of the plate and strip must be cleaned in the finished coil, otherwise slip bands are likely to occur during coiling, and the residue of lubricating fluid after annealing will pollute the surface of the plate and strip and affect product quality. Therefore, a degreasing and cleaning device must be installed before and after the rolling mill. Although some multi-roller degreasing devices currently used have better degreasing and cleaning effects, the strip needs to be bent and deformed many times during the degreasing and cleaning process, which may cause permanent deformation of the strip and affect product quality.

Utility model content

Aiming at the problem that the existing multi-roller degreasing device easily causes permanent deformation of the plate and strip, the utility model provides a center-offset surface cleaning device for the plate and strip. The device includes a lower roller and an upper roller which are parallel to each other and respectively arranged on the lower support and the upper support. The centers of the upper rollers and the lower rollers are offset to some extent in the horizontal direction.

The technical scheme of the utility model is realized in the following way: the surface cleaning device of the plate and strip, which includes an upper roller and a lower roller, and is characterized in that the upper roller is fixed into one body with the hydraulic oil cylinder through the upper bracket, and the upper bracket is installed on the On the guide column of the frame, the upper bracket can slide up and down along the guide column through the drive of the hydraulic cylinder; the lower roller and the lower bracket are fixed together, and the lower roller and the lower bracket are fixed to the frame through the adjustment bolt of the reduction amount Together; the upper roller and the lower roller are parallel to each other; the center of the upper roller and the center of the lower roller have a certain degree of deviation in the horizontal direction.

The main feature of the utility model is that the upper roll and the lower roll are parallel to each other, the center of the upper roll and the center of the lower roll have a certain degree of deviation in the horizontal direction, and only the strip is cleaned during the cleaning process. One-time bending can increase the friction between the upper roller, the lower roller and the strip to achieve a good degreasing and cleaning effect, and at the same time prevent the permanent deformation of the strip.

The technical solutions of the present utility model will be further described in detail through the drawings and embodiments below.

Description of drawings

Fig. 1 is the structural representation of the utility model strip material surface cleaning device;

Fig. 2 is a sectional view of the utility model strip surface cleaning device;

In the figure: 1. Upper roller; 2. Upper bracket; 3. Hydraulic cylinder; 4. Lower roller; 5. Lower bracket; .

Detailed ways

As shown in Figure 1 and Figure 2, the frame 6 is respectively installed in the front and rear of the rolling mill, the upper roll is connected with the hydraulic cylinder 3 through the upper bracket 2; the lower roll 4 is fixed with the lower bracket 5, and the lower roll The lower bracket is fixed together with the frame 6 through the reduction adjustment bolt 7, and the cleaning effect can be controlled by adjusting the deformation of the strip between the upper stick device and the lower stick device through the reduction adjustment bolt 7.

As shown in FIG. 2 , the center of the upper roll 1 and the center of the lower roll 4 deviate to some extent in the horizontal direction. The distance between the center of the upper roll 1 and the center of the lower roll 4 in the vertical direction is smaller than the sum of the radii of the upper roll 1 and the lower roll 4 .

The working process of the utility model is that when the belt is threaded, the upper roller 1 is lifted by the hydraulic cylinder through the upper bracket 2, and it is pressed down during work, forcing the plate and strip to produce bending deformation between the upper roller and the lower roller. It can be adjusted according to strips of different materials and thicknesses to achieve a better cleaning effect. At the same time, since the strip is only bent once during the cleaning process of the strip, it can effectively prevent the strip from being permanently damaged. out of shape.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be The new technical solution shall be modified or equivalently replaced without departing from the spirit and scope of the technical solution of the present utility model.
