Description
Technical Field
The utility model relates to a steel rolling equipment technical field especially relates to a spacing protection device of working roll surface.
Background
In a heavy and medium plate mill, the clearance between the roll surface of a working roll and water cutting plates at two sides of the working roll is generally 2-3.5 mm. In the production process of the medium plate mill, the water cutting plate is impacted back and forth by the steel plate, so that the gap between the water cutting plate and the roll surface of the working roll is reduced, the water cutting plate can rub the roll surface when contacting the roll surface of the working roll, the roll surface of the working roll is scratched, roll marks are generated on the surface of the rolled steel plate directly, and the quality problem of the steel plate is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that, overcome prior art's shortcoming, provide a spacing protection device of work roll surface.
In order to solve the technical problem, the technical scheme of the utility model as follows:
the utility model provides a spacing protection device of working roll surface, includes the working roll and is located the cutting plate of working roll both sides, the cutting plate orientation the both ends of working roll one side all are provided with the stopper, just the stopper is located in the non-rolling district at working roll both ends, the stopper orientation one side of working roll with interval between the working roll surface is less than the cutting plate orientation one side of working roll with interval between the working roll surface.
As a work roll surface spacing protection device's an optimal selection scheme, wherein: the stopper orientation one side of working roll with the interval between the working roll surface with the difference of the tangent plate orientation one side of working roll with the interval between the working roll surface is 1.5 mm.
As a work roll surface spacing protection device's an optimal selection scheme, wherein: the limiting block is welded on the water cutting plate.
As a work roll surface spacing protection device's an optimal selection scheme, wherein: the limiting blocks are made of wear-resistant steel.
The utility model has the advantages that:
(1) the utility model discloses weld the stopper at the both ends of cutting water board, and this stopper is located the non-rolling district at work roll both ends, in the process that the clearance between cutting water board and the work roll surface reduces gradually, the roll surface of work roll can contact with the stopper earlier, makes the interval between the roll surface of work roll and the cutting water board can't further reduce, and the stopper is located the non-rolling district at work roll both ends, therefore the contact of stopper and work roll can not produce the influence to the rolling district roll surface of work roll, thereby the roll surface in the rolling district of work roll has effectively been protected;
(2) the limiting block of the utility model is made of wear-resistant steel, has good wear resistance and prolongs the service life of the limiting block;
(3) the utility model discloses still can weld the adjustment according to the thickness of the wearing and tearing condition of on-the-spot in service behavior and stopper.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without inventive labor.
Fig. 1 is a schematic structural view of a working roll surface limiting and protecting device provided by the present invention;
wherein: 1. a work roll; 2. a water cutting plate; 3. and a limiting block.
Detailed Description
In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
The embodiment provides a spacing protection device of 1 roll surface of work roll, including work roll 1, all install cutting board 2 in the both sides of work roll 1. All welded at the both ends of cutting water board 2 has stopper 3, and this stopper 3 all is located cutting water board 2 towards one side of working roll 1, and the stopper 3 is less than cutting water board 2 towards the interval between one side of 1 roll surface of working roll and the 1 roll surface of working roll 1 and the interval between one side of 1 roll surface of working roll and the working roll surface of working roll 1.
It should be noted that the length of the work roll 1 is generally greater than the width of the rolled steel sheet, for example, the length of the roll surface of the work roll 1 is 3500mm, and the width of the rolled steel sheet is less than 3300m, so that there are 100mm wide non-rolling regions at both ends of the work roll 1, and the non-rolling regions do not contact with the steel sheet during the operation of the work roll 1. The limiting blocks 3 arranged at the two ends of the water cutting plate 2 are respectively positioned in the non-rolling areas at the two ends of the working roll 1.
The medium plate rolling mill is in the production process, the water cutting plate 2 is impacted back and forth by the steel plate, the gap between the water cutting plate 2 and the roll surface of the working roll 1 can be reduced, the gap is in the reduction process, the roll surface of the working roll 1 can be contacted with the limiting block 3 firstly, the distance between the roll surface of the working roll 1 and the water cutting plate 2 can not be further reduced, the limiting block 3 is positioned in the non-rolling area at the two ends of the working roll 1, therefore, the contact between the limiting block 3 and the working roll 1 can not influence the roll surface of the rolling area of the working roll 1, and the roll surface of the rolling area of the working roll 1 is effectively protected.
Preferably, the difference between the distance between one side of the limiting block 3 facing the roll surface of the working roll 1 and the distance between one side of the water cutting plate 2 facing the roll surface of the working roll 1 and the roll surface of the working roll 1 is 1.5 mm.
In addition, the limiting block 3 is made of wear-resistant steel, so that the wear resistance is good, and the service life of the limiting block 3 is greatly prolonged. And can weld the adjustment to stopper 3 according to the wearing and tearing condition of on-the-spot service behavior and stopper 3, adjust the stopper 3 towards the interval between 1 roll surface of working roll 1 and the roll surface of working roll 1.
Therefore, the utility model discloses a welding stopper 3 at 2 both ends of cutting water board, avoided 1 roll surface of working roll and 2 inboard contacts of cutting water board and lead to the roll surface fish tail in 1 rolling district of working roll, effectively protected the roll surface in 1 rolling district of working roll.
In addition to the above embodiments, the present invention may have other embodiments; all the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
