Abstract

The invention relates to rolling production, namely, devices for centering a moving strip. The purpose of the invention is to improve the accuracy of centering. A device for centering the moving strip 1 consists of centering rollers 2 mounted on both sides of the centering axis of the strip, and a deflection roller mounted behind them. Each roller 2 is mounted by the actuator 6 at a certain angle a to the plane of movement of the strip, and the magnitude of this angle is different for each roller, so that the upper forming rollers form a convex curved surface. When the strip deviates from the axis of the unit, one of its sides moves onto the rollers 2. A part of the strip is bent with the help of centering rollers and falls on the deflection roller with an offset. The tension of this part of the strip is higher, higher and the magnitude of the cohesive forces of the strip with the deflecting roller. Due to the increased adhesion of the displaced part of the strip with the deflecting roller and the rigidity of the strip, it gradually shifts to the axis of the aggregate. 5 il. (L

The invention relates to rolling production, and more specifically to devices for centering a moving strip, preferably thin, and can be used in continuous assemblies.

The purpose of the invention is to increase the accuracy of centering.

FIG. 1 shows the installation of the device in the line of the unit; in fig. 2 - the position of the strip at the time of centering; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a plan view; in fig. 5 is a view B in FIG. 3

The device for centering the moving strip 1 consists of centering rollers 2 mounted on both sides of the axis 3 centering the strip on moving frames 4, having the ability to move in the direction perpendicular to the direction of movement of the strip from the drive 5. Each roller 2 is equipped with a tilt drive 6, along The movement of the strip 1 is provided with a deflection roller 7.

The device works as follows.

Each roller 2 is installed by the actuator 6 at a certain angle a to the plane of movement of the strip, and the magnitude of this angle is different for each roller, so that the upper forming rollers 2 form a convex curvilinear surface (Fig. 5). The shape of this surface (i.e. the angles of inclination of the rollers 2) is determined by the mechanical properties of the centered strip.

The distance between the rows of the rollers 2 in the direction perpendicular to the movement of the strip 1 is established by the actuator 5 on the basis of the width of the strip so that its edges touch the rollers 2. be installed with a gap in relation to lane 1.

The strip moving in the assembly line along its axis 3 does not touch the rollers 2. When removed

the inclination of the strip from the axis 3 of the aggregate, one of its sides moves onto the rollers 2 and takes the shape corresponding to the convex curve formed by them, while

as the angle of inclination of the rollers 2 increases gradually, there is no strong deformation of the strip.

Upon further movement of strip 1 to deflecting roller 7, part of the strip is bent by means of centering rollers on roller 7 shifted to the axis of the aggregate, the tension of this part of the strip is slightly higher than the rest of the strip, therefore, more than the magnitude of the adhesion forces contact of this part

5 with roller 7 (Fig. 2). Due to the increased adhesion of the displaced part of the strip with the deflecting roller (in comparison with the rest of the strip) and the rigidity of the strip, it gradually shifts to the axis 3 of the aggregate.

When switching to another bandwidth of the frame 4, the drive 5 moves from the axis 3 of the unit.

The effect of using the proposed device is to improve the accuracy of strip centering.
