Abstract
The utility model discloses a segmented roller of a continuous casting machine. A shaft shoulder is used as transition between a roller body and a shaft neck, a smooth curved surface of an axial indent is used as transition between the outer circle of the shaft shoulder and the end face of the roller body, the shaft shoulder with the diameter larger than that of the shaft neck is arranged on the transition part between the segmented roller body and the shaft neck so as to ensure that the shaft neck is gradually transitioned to the end face of the roller body and avoid the occurrence of stress concentration, thereby enhancing the capability of the transition part between the segmented roller and the shaft neck on bearing torque and vertical load, prolonging the service cycle of the segmented roller, avoiding frequent fracture during use, guaranteeing the long-term smooth running of the production and saving production cost.
Description
Technical field
The utility model relates to a kind of conticaster auxiliary equipment component, particularly a kind of conticaster metamerism roller.
Background technology
High-temperature molten steel continuously is cast into the production process with certain section configuration and certain size specification strand is called continuous casting steel machine.Finish the required equipment of this process the continuous casting complete set of equipments, comprise the steel equipment that waters, conticaster body equipment, cutting zone equipment, dummy bar collection and conveying equipment.
The conticaster metamerism roller is to be used in casting blank solidification end, for improving the bending resistance of roller, reduces the harmful effect of casting blank deformation to slab quality, and general conticaster adopts thin roller to gather and two metamerism rollers.
Directly smooth transition surface transition between the metamerism roller body of roll and the axle journal by concaving in week, because the transition structure of the axle journal and the body of roll is unreasonable, the transition position gradient is relatively large, have than obvious stress and concentrate, owing to bear bigger radial load, cause the transition position of the axle journal and the body of roll frequently to rupture during use.
Therefore, need improve, increase the ability that metamerism roller bears moment of torsion and vertical load existing metamerism roller, thereby the life cycle that can prolong metamerism roller, avoid in use frequently rupturing, thereby guarantee that the long period of producing carries out smoothly.
The utility model content
In view of this, the utility model provides a kind of conticaster metamerism roller, increases the ability that metamerism roller bears moment of torsion and vertical load, thereby the life cycle that can prolong metamerism roller, avoids in use frequently rupturing, thereby guarantees that the long period of producing carries out smoothly.
Conticaster metamerism roller of the present utility model comprises the body of roll and axle journal, and by shaft shoulder transition, shaft shoulder cylindrical and end surface of roll are by the smooth surface transition of axial indent between the described body of roll and the axle journal.
Further, the cross section molded lines of described smooth surface is followed successively by arc section I, arc section II that fuses and the straightway that tilts to body of roll cylindrical from the inside to the outside by shaft shoulder cylindrical to end surface of roll, and described straightway and arc section II are tangent;
Further, the radius of described arc section I is greater than the radius of arc section II;
Further, the angle of described straightway and axis is 30 °.
The beneficial effects of the utility model: conticaster metamerism roller of the present utility model, transition position is provided with the shaft shoulder of diameter greater than axle journal between the metamerism roller body of roll and the axle journal, make axle journal progressively transit to end surface of roll, avoiding occurring stress concentrates, thereby increasing the ability that metamerism roller and axle journal transition position bear moment of torsion and vertical load, the life cycle that can prolong metamerism roller is avoided in use frequently rupturing, thereby guarantee that the long period of producing carries out smoothly, saves production cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Accompanying drawing is a structural representation of the present utility model, as shown in the figure: the conticaster metamerism roller of present embodiment, comprise the body of roll 1 and axle journal 2, by the shaft shoulder 3 transition, the shaft shoulder 3 cylindricals and the body of roll 1 end face are by the smooth surface transition of axial indent between the described body of roll 1 and the axle journal 3.
In the present embodiment, the cross section molded lines of described smooth surface is followed successively by arc section I 4, arc section II 5 that fuses and the straightway 6 that tilts to the body of roll 1 cylindrical from the inside to the outside by the shaft shoulder 3 cylindricals to the body of roll 1 end face, and described straightway 6 is tangent with arc section II 5;
In the present embodiment, the radius of described arc section I 4 is greater than the radius of arc section II 5; Make transition position circular arc radius gradually descending, strengthen the ability of axle journal and transition position junction torque resistant and moment of flexure, and further reduce stress and concentrate, thereby improve the external force resistance ability of metamerism roller integral body.
In the present embodiment, described straightway 6 is 30 ° with the angle of axis.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
Claims (4)
