Technical Field
The utility model relates to a red circle rolling mill field of short stress specifically is a quick prosthetic devices of short stress rolling mill axial dislocation roller.
Background
At present, a short-stress red ring rolling mill is used in a rolling line of a bar mill, and the short-stress red ring rolling mill is unstable in work all the time and mainly comprises the problem of roller dislocation; the main reason for the above is that the short-stress red ring rolling mill has a gap in the direction parallel to the pull rod and is unstable in the direction perpendicular to the pull rod; the reasons directly affect the rolled piece size and product quality.
At present, most of data mainly focus on improving the control precision of a fixed end of a short-stress rolling mill, and no relevant data is deeply described in the aspect of assembly and maintenance;
in conclusion, how to prevent the plastic deformation of the pull rod during rolling becomes a problem which needs to be solved urgently by researchers of the company, and the amount of the wrong roller is controlled within 0.35 mm.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to prevent the pull rod from plastically deforming during rolling;
in order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model relates to a short stress rolling mill axial staggered roll quick repairing device, which comprises a bearing seat; a pull rod is movably sleeved in the bearing seat; a copper nut is sleeved on the pull rod; an annular bulge which is abutted against the inner wall of the bearing seat is protruded on the copper nut; a shaft sleeve is arranged above the annular bulge and in a gap between the inner wall of the bearing seat and the outer wall of the copper nut; the shaft sleeve is sleeved on the copper nut;
conventional copper nut only has convex annular protrusion and offsets with the bearing frame inner wall, consequently has the clearance between copper nut and the bearing housing inner wall, works the back for a long time when copper nut, and the pull rod can take place elastic deformation at rolling in-process because the existence in clearance, leads to the appearance of wrong roller, for solving this problem, through being provided with the axle sleeve in clearance department, the axle sleeve fills out the clearance department of establishing at copper nut and bearing frame inner wall to can reduce the elastic deformation volume of pull rod.
In order to quickly replace the shaft sleeve, the utility model adopts the technical scheme that the upper end surface of the shaft sleeve is provided with a threaded hole;
screw rod precession screw hole for the screw rod lifts the screw rod this moment with the fixed of axle sleeve, breaks away from clearance department with the axle sleeve, the quick replacement axle sleeve of being convenient for.
The utility model has the advantages that: the utility model relates to a short stress rolling mill axial fault roll quick prosthetic devices through being provided with the axle sleeve between copper nut and bearing inner wall, prevents that the pull rod from taking place elastic deformation at rolling in-process, reduces the appearance of wrong roller.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1 and 3, the utility model relates to a short stress rolling mill axial staggered roll quick repairing device, which comprises a bearing seat 1; a pull rod 2 is movably sleeved in the bearing seat 1; a copper nut 3 is sleeved on the pull rod 2; an annular bulge 4 which is abutted against the inner wall of the bearing seat 1 is protruded on the copper nut 3; a shaft sleeve 5 is arranged above the annular bulge 4 and in a gap between the inner wall of the bearing seat 1 and the outer wall of the copper nut 3; the shaft sleeve 5 is sleeved on the copper nut 3;
conventional copper nut only has convex annular protrusion and offsets with the bearing frame inner wall, consequently has the clearance between copper nut and the bearing housing inner wall, works the back for a long time when copper nut, and the pull rod can take place elastic deformation at rolling in-process because the existence in clearance, leads to the appearance of wrong roller, for solving this problem, through being provided with the axle sleeve in clearance department, the axle sleeve fills out the clearance department of establishing at copper nut and bearing frame inner wall to can reduce the elastic deformation volume of pull rod.
As shown in fig. 3, in order to rapidly replace the shaft sleeve, the utility model adopts a threaded hole 8 formed on the upper end surface of the shaft sleeve 5;
screw rod precession screw hole for the screw rod lifts the screw rod this moment with the fixed of axle sleeve, breaks away from clearance department with the axle sleeve, the quick replacement axle sleeve of being convenient for.
As shown in figures 1-3, the utility model relates to a quick prosthetic devices of short stress rolling mill axial dislocation roller through being provided with the axle sleeve between copper nut and bearing inner wall, prevents that the pull rod from taking place elastic deformation at rolling in-process, reduces the appearance of dislocation roller.
In order to further explain the method for quickly repairing the short-stress red ring rolling mill axial staggered roller, the method comprises the following steps:
1. the fixing screw 10 above the transparent cover 6 is removed
2. The reasonable inner hexagonal is selected to remove the bolt 12 at the gland 11 to take down the gland 11
3. The stopper pin 13 engaged with the copper nut 3 is taken out using an extractor
4. The transparent cover 9 moves upwards along the axial direction of the pull rod 2, and a proper space is left
5. A specially-made copper nut fastening open spanner is stretched into a gap between the transparent cover 6 and the bearing seat 1 and is aligned to a bolt hole above the copper nut 3 to fasten the copper nut 3
6. Eliminating the gap between the copper nut 3 and the spherical pad 14, so that the pull rod 2, the copper nut 3 and the support seat 7 form a whole;
7. the stop pin 13 and the gland 11 are arranged in the bearing seat 1 and fixed by the bolt 12
8. A pair of cut shaft sleeves 5 are placed between the bearing seat 1 and the copper nut 3 so as to reduce the gap between the bearing seat 1 and the copper nut 3 on the pull rod 2 (the shaft sleeves 5 are made of wrought iron, the gap between the shaft sleeves 5 and the bearing seat 1 is 0.05mm, and 3 internal thread holes are processed on the end surface of the shaft sleeves 5 in order that the shaft sleeves 5 can be quickly taken out after being worn in future)
9. Because the transparent cover 6 is matched with the copper nut 3 for a long time, the conclusion is obtained through multipoint measurement collection and verification: the average abrasion is 0.15-0.2mm, and a copper gasket 9 with the thickness of 0.2-0.3mm is added between the copper nut 3 and the pressing block of the transparent cover 6, so that the transparent cover 6 is ensured to tightly press the copper nut 3.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
