Technical Field
The utility model relates to a steel production accessory, in particular to a straightening device for controlling the upwarp of a thick-plate high-strength steel strip head at an outlet of a continuous pickling galvanizing unit.
Background
The head of the strip steel of the acid pickling galvanizing unit in the prior art is always warped when producing a thick plate of more than 3.0, particularly, the warping is more serious when producing high-strength steel with yield strength of more than 400MPa, the height of the warping is sometimes larger than the opening degree of a shearing machine, the steel is clamped at a flying shear part, even a production line shutdown accident is caused, and the production rhythm of a production line is influenced. Meanwhile, the warping of the belt head frequently impacts roller systems (a carrier roller and a winding steering roller) at an outlet, so that the roller systems are seriously abraded, and the roller period is shortened. In addition, the risk of roll marks and scratches is increased, and the product quality is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides a three-roller straightening device for improving the upwarp of a thick-plate high-strength steel strip head.
The technical scheme for solving the technical problem is as follows: the utility model provides an improve three-roller straightener that slab high strength steel strip head warped upwards which characterized in that: comprises a bracket, a connecting beam, a lifting hydraulic cylinder, a lifting roller and a fixed upper roller; the number of the supports is two, and the lower parts of the supports are fixed on the equipment base; the two brackets are fixedly connected through a connecting cross beam; the two fixed upper rollers are fixed on the bracket through bearing seats, two ends of each fixed upper roller are perpendicular to the direction of the rolling line, and the lower edge of the roller surface is consistent with the height of the rolling line; the lifting roller is parallel to the fixed upper roller, and the bearing seats at two ends are connected with the upper end of the lifting hydraulic cylinder.
The number of the connecting cross beams is four.
Compared with the prior art, the utility model has the following outstanding beneficial effects:
1. according to the utility model, by straightening the buckling defect of the strip head of the thick-plate high-strength steel, the strip steel keeps straight after being sheared by the flying shear, the steel clamping phenomenon of the outlet is reduced, the frequency of impact on the outlet roller system is reduced, the fault time is reduced, and the machine hour yield of the elevator is increased;
2. the abrasion of the outlet roller system is reduced, and the service cycle of the outlet roller is prolonged;
3. the device has low design cost, simple operation and convenient popularization.

FIG. 1 is a side view of the present invention.
Fig. 2 is a schematic front view of the present invention.
Detailed Description
The utility model is further described with reference to the drawings and the detailed description. In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the claimed embodiments. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
In the following embodiments, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; the connection can be mechanical connection, electrical connection or communication; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the embodiments of the present application can be understood by those skilled in the art according to specific situations.
It is to be understood that the terms "central," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," "end," "side," and the like are used in an orientation or positional relationship indicated in the drawings for convenience in describing the claimed embodiments and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the claimed embodiments.
As shown in fig. 1 and 2, an embodiment 1 of the present invention includes a support 1, a connecting beam 2, a hydraulic cylinder 3, a liftable roller 5, and an upper fixed roller 6.
The utility model is arranged between a No. 11 tension roller and an oiling machine of a continuous pickling galvanizing unit.
The two supports 1 are oppositely arranged, and the lower parts of the supports are fixed on the equipment base. The two supports are fixedly connected through the connecting cross beams 2, and in the embodiment, the number of the connecting cross beams 2 is four.
The two fixed upper rollers 6 are fixed on the bracket 1 through bearing seats at two ends, and can be integrally hoisted and replaced. The fixed upper roller 6 is fixed and vertical to the direction of a rolling line, and the lower edge of the roller surface is consistent with the height of the rolling line.
The lifting roller 5 is parallel to the fixed upper roller 6, and the bearing seats at the two ends are connected with the upper end of the lifting hydraulic cylinder 3. The lifting hydraulic cylinder 3 is used for controlling and adjusting the roller height of the lifting rollers 5, when the hydraulic cylinder retracts, the lifting rollers 5 are located at the low position and are not in contact with the strip steel, when the hydraulic cylinder extends out, and the roller surfaces of the lifting rollers 5 are higher than a rolling line, the strip steel 7 can be bent, and by combining the tension action of the strip steel 7, the position of the lifting rollers 5 is controlled, so that the thick strip steel 7 can be cut to be straight.
In order to increase the stability and the synchronism of the liftable roller 5, the embodiment 2 is optimized as follows:
a base is arranged between the bearing seat of the lifting roller 5 and the upper end of the lifting hydraulic cylinder 3, two ends of a connecting shaft are connected with the base, and two ends of the connecting shaft are respectively connected with a synchronous wheel 4 in a rotating mode.
The side wall of the inner wall of the support 1 is provided with a lifting guide rail 8, the synchronous wheels 4 are arranged in the lifting guide rail 8, and the synchronous wheels 4 can only move along the lifting guide rail 8 due to the limitation of the lifting guide rail 8 so as to achieve the effects of realizing the stability and the synchronism of the lifting rollers 5.
The synchronous wheels 4 and the lifting guide rails 8 are optimized to be a pair, and are arranged bilaterally or unilaterally.
It should be noted that the present embodiment is not described in detail, and is a technique known in the art.
While specific embodiments of the utility model have been described above for purposes of illustration, it will be apparent to those skilled in the art that various obvious changes can be made without departing from the spirit and scope of the utility model.
