Abstract

The invention relates to rolling equipment and is intended for use primarily in workshops where widebands are dispersed into narrow ones, as well as in the workshops of machine-building enterprises. The purpose of the invention is to improve the quality and improve working conditions. The tapes before winding on the drum are fed to the centering roller and placed between the separating disks 1. Under the action of the winding tapes, the centering roller rotates. The edges of the belts contact and rub against the side surfaces of the separating discs 1. The radially directed depressions 6 and the protrusions 7 which are formed on the lateral surfaces alternately come into contact with the edges of the belt. The forced vibrations of the separating disk are directed along its axis. In contact with the edge of the tape, inserts of copper-containing material transfer copper atoms to the edges of the tape by rubbing. From the edges of the tape, copper atoms are transferred by rubbing onto the protrusions of the side surfaces of the separating discs. In the course of the belt movement, this ensures frictionless wear on the contact surfaces due to the effect of selective transfer. Elastic noise-absorbing elements (rubber rings) allow the separator discs to oscillate while simultaneously absorbing. 3 il.

Description

The invention relates to rolling equipment and is intended for use mainly in workshops where wide ellies are dispersed into narrow ones with a winder of a slitting unit wound on a drum, and also in workshops of machine-building enterprises where strips of slit metal are used.

The aim of the invention is to improve the quality and improve the conditions

FIG. 1 shows a centering roller, a general view; in fig. 2 - separation disc; in fig. 3 - separator disk, expanded section.

The centering roller contains separating discs 1 fixed on axis 2 mounted rotatably in supports 3. Alternate radially directed depressions 6 and protrusions 7 are arranged on side surfaces A and 5 of each disk 1. Converse edges 6 on lateral surface 4 are located opposite projections 7 on the lateral surface 5. In the radial direction, the disks are fixed on the axis through elastic noise absorbers made in the form of rings 8, and in the axial direction - through elastic noise-absorbing elements in the form of rings 9. In the depressions 6 on the side The surfaces 4 and 5 of the separating discs 1 are placed with inserts 10 of copper-containing material.

FIG. 1 also shows the separable tapes 11.

Centering roller works in a specific way.

The belts 11 before winding on the drum coiler to prevent overwhelming and displacement from the axis of the winding are fed to the centering roller, where they are placed between the separating discs 1. Under the action of the belts reeled on the coiler, the centering roller rotates and the edges of the belts 11 contact and rub the side separating disc surfaces 1. Radially directed depressions and protrusions formed on side surfaces alternately come into contact with

the edges of the tape, thereby creating forced oscillations of the separating disk, directed along its axis. In this case, the contact of the edge of the tape and the side surface of the disk is made periodically. In contact with the edge of the tape, the insert 10 of copper-containing material transfer copper atoms to the edges of the tape by rubbing. From the edges of the tape, copper atoms are transferred by rubbing onto the protrusions of the side surfaces of the separating discs. During the movement of the tape, atoms are interchanged between the protrusions of the separating disks and the edges of the tape, thereby ensuring wearless friction on the contact surfaces due to the effect of selective transfer.

Elastic noise-absorbing elements - rubber rings 8 and 9 allow the separator discs to oscillate while simultaneously absorbing.
