Abstract

The utility model relates to a high precision stretch bending straightening unit, which overcomes the problems that an existing unit carries out stretch bending and straightening only through one 23 roller straightening machine, device accidents are easily generated, and strip flattening and remnant stress elimination are affected. The high precision stretch bending straightening unit comprises a first decoiler 1, a first steering roll 2, a first tension roll group 3, a stretch bending straightening machine 4, second tension roll groups 5 and 23, a roller straightening machine 6, a third tension roll group 7, an inspection skid 8, a steering roll 9 and a reeling machine 10.

Description

A kind of high accuracy stretch-bending straightening unit

One, technical field

The utility model relates to a kind of band stretch-bending straightening device, specifically is meant a kind of high accuracy stretch-bending straightening unit.

Two, background technology

Existing band is in the stretch-bending straightening process, the stretching of band and leveling are all finished on 23 roller straighteners, just must strengthen strap tension and increase cornerite for the relatively poor band of plate shape, machine utilization is increased, very easily causing the working roll roll breakage or the roller of 23 roller straighteners is equipment breakdowns such as heating, especially can when the higher thick band of production straightening intensity, take place, just must increase the pivot angle of straightener top working roll or the coincidence amount of working roll and increase cornerite, can have influence on the leveling of band and the elimination of residual stress thus, and thereby the higher thick band of intensity very easily causes roller system heating limit production speed, so the speed of production of home equipment can only reach about 60 meters of per minutes at present.

Three, utility model content

The purpose of this utility model provides a kind of high accuracy stretch-bending straightening unit, only carries out stretch-bending straightening by one 23 roller straightener to overcome existing unit, causes equipment breakdown easily and influences the band leveling and the problem of residual stress elimination.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of high accuracy stretch-bending straightening unit, comprise the uncoiler, first slewing rollers, the second jockey pulley group, 23 roller straighteners, the 3rd jockey pulley group, inspection desk, second slewing rollers and the coiling machine that set gradually, it is characterized in that: also comprise the stretching-bending straightener and the first jockey pulley group, wherein the stretching-bending straightener and the first jockey pulley group are arranged between first slewing rollers and the second jockey pulley group.

Compared with prior art, the utlity model has following advantage:

1, can improve the glacing flatness of plate shape, further eliminate residual stress, reduce the load of 23 roller straightener rollers system, reduce equipment breakdown, speed of production can reach about 100 meters of per minutes;

The band that 2, can adapt to the irregular variation of plate shape satisfies the needs of production high accuracy band fully.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model;

Among the figure, 1-uncoiler, 2-first slewing rollers, the 3-first jockey pulley group, 4-stretching-bending straightener, the 5-second jockey pulley group, 6-23 roller straightener, 7-the 3rd jockey pulley group, 8-inspection desk, 9-second slewing rollers, 10-coiling machine.

Five, the specific embodiment

Referring to Fig. 1, a kind of high accuracy stretch-bending straightening of the utility model unit is made up of the uncoiler 1 that sets gradually, first slewing rollers 2, the first jockey pulley group 3, stretching-bending straightener 4, the second jockey pulley group, 5,23 roller straighteners 6, the 3rd jockey pulley group 7, inspection desk 8, slewing rollers 9 and coiling machine 10;

The utility model has increased a stretching-bending straightener 4 and the first jockey pulley group 3 in original unit, because stretching-bending straightener 4 rollers are the intensity height, can bear very big tension force, make the plate shape that does not have rule to change reach straight requirement substantially, and then impose than small tension receiving coil by 23 roller straighteners 6, further eliminate residual stress, improve the glacing flatness of plate shape.This kind collocation mechanism of the present utility model, can reduce the load of 23 roller straighteners, 6 rollers system, reduce equipment breakdown, make speed of production reach about 100 meters of per minutes, also adapt to simultaneously the band of the irregular variation of plate shape, the stretch-bending straightening unit of this kind configuration has significantly improved the precision and the speed of production of band.

Claims (1)

1, a kind of high accuracy stretch-bending straightening unit, comprise the uncoiler (1), first slewing rollers (2), the second jockey pulley group (5), 23 roller straighteners (6), the 3rd jockey pulley group (7), inspection desk (8), second slewing rollers (9) and the coiling machine (10) that set gradually, it is characterized in that: also comprise the stretching-bending straightener (4) and the first jockey pulley group (3), wherein the stretching-bending straightener (4) and the first jockey pulley group (3) are arranged between first slewing rollers (2) and the second tension roller group (5).
