SU1292890A1 - Arrangement for riffling rolled mill rolls - Google Patents

Abstract

The invention relates to tools for grooving rolls directly in the mill stands and allows for knurling barrel rolls. For this, the tool for corrugation is made in the form of plastic with a working relief surface, having the form of bars fixed on the elastic base of the device. The bars move independently in the radial direction relative to the rolls. This ensures that the load on the tool elements is equalized and the roll shape is copied. 3 il. ju co | c 00 co

Description

The invention relates to tools for applying riffles on rolls directly in the mill stands.

The purpose of the invention is to expand the technological capabilities of the device by providing grooved barrel rolls.

FIG. 1 shows a device for grooving rolls, general view; in fig. 2. - section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2

The device for grooving rolls consists of a housing 1, in the grooves 2 of which is placed a tool for grooves, made in the form of a set along the width

When grooved barrel rolls 8, i.e. rolls with a variable roll diameter over the barrel length, each of the bars 3 that make up the tool for corrugation moves in a vertical direction by a different size, i.e. the bar located under a large diameter roll 8, bends the elastic element 4 by a large amount due to the elastic element 6 located under it, which,

The bar 3, which is under a large diameter of the roll 8, has a greater degree of bonding between the flanks and a vertical displacement, which is -1 rf-cpe Jr с, д, .ссГр-;

Ment 4 placed the elastic elements 6 and 7. The 20th element 4.

The device is installed by a bridge crane on the roller table, is fed by the roller table to the rolls 8 and 9 and is positioned against the roll section to be grooved with the help of ruler handles. The device is then fed to the rollers 8 and 9, and the press mechanism of the mill is compressed between the rotating rollers — a straight pass is performed.

At the rear of the mill, the apparatus is moved with rulers along the roll barrel, and then the reverse pass is similarly performed.

Sequentially moving the device along the roll barrel, the entire surface of the rolls is grooved.
