Abstract
The invention relates to the technical field of roller repairing, in particular to a structure and a repairing method of a roller. The structure comprises a roller shaft and a roller body, wherein the roller body is provided with a roller core and a roller sleeve which is detachably arranged outside the roller core; after the roller sleeve is worn, the worn part is filled and leveled up and the welding is repaired; the weld joint is worn smooth; and because the diameter of the roller sleeve is less than that during installation, a new roller sleeve layer is rewrapped outside the roller sleeve. After the roller sleeve is worn, the roller sleeve can be disassembled and substituted by a new roller sleeve; and the structure and the repairing method have the advantages of prolonging the service life of the roller, repairing for several times, reducing the material cost and improving the working efficiency, along with simple operation, convenient disassembling and high practicability.
Description
Technical field
The present invention relates to the structure and the restorative procedure of technical field, the especially roll of roll reparation.
Background technology
The used restorative procedure of present most of roll is built-up welding, but built-up welding is easy to peel off, and the hardness of the roll after the built-up welding is inhomogeneous, and the restorative procedure of built-up welding can only be repaired twice, the roll that will more renew again, unusual waste material so, cost increases.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in the prior art, a kind of structure and restorative procedure of roll is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of roll, comprise roll mandrel and roll body, roll body have roller core and be enclosed within the roller core outside can dismounting roller shell.
The two ends of described roller shell are fixedly connected by welding.
The material of described roll is materials such as steel, cast iron.
The restorative procedure of roll, method step is: after the roller shell wearing and tearing, with fray fill and lead up, repair welding, weld is polished because the diameter that the diameter of roller shell can be when installing is little, wrap up the new roller shell of one deck again in the outside of roller shell.
The invention has the beneficial effects as follows: after the roller shell wearing and tearing of the present invention, roller shell can be removed, change new roller shell, simple to operate, easy disassembly takes technology among the present invention can prolong the service life of roll, can repeatedly repair, reduce the cost of material, improved operating efficiency, practical.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the side view of Fig. 1.
Among the figure: 1. roll mandrel, 2. roll body, 2-1. roller core, 2-2. roller shell.
The specific embodiment
The present invention is further illustrated with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of roll as depicted in figs. 1 and 2 comprises roll mandrel 1 and roll body 2, roll body 2 have roller core 2-1 and be enclosed within the roller core 2-1 outside can dismounting roller shell 2-2, the two ends of roller shell 2-2 are fixedly connected by welding, the material of roll is materials such as steel, cast iron.
The restorative procedure of roll, method step is: after the roller shell wearing and tearing, with fray fill and lead up, repair welding, weld is polished,, wrap up the new roller shell of one deck again in the outside of roller shell because the diameter that the diameter of roller shell can be when installing is little, new roller shell and old roller shell have been taked interference fit, new roller shell and can repeatedly repairing has improved the service life of roll, has saved cost.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (4)
1. a roll comprises roll mandrel (1) and roll body (2), it is characterized in that: roll body (2) have roller core (2-1) and be enclosed within roller core (2-1) outside can dismounting roller shell (2-2).
