Description
Technical field
This utility model relates to sinking roller, particularly a kind of sinking roller.
Background technology
Sinking roller is one of visual plant of galvanization production line, the corrosiveness of zinc liquid is received in hot galvanizing line production process, simultaneously under strip tension effect, sinking roller can be by certain frictional force, so being easy to that sinking roller axle journal slipper wear damage occurs, decrease the service life of sinking roller.Sinking roller is during using; in order to improve the zinc adhesive force in steel strip surface; a small amount of aluminium alloy element can be added in zinc liquid; in roller operation process, zinc liquid is often deposited in the middle of roller, and zinc liquid comes in contact with roller, produces zinc-iron alloy too and is attached to roller surfaces; after using for a long time; can constantly increase due to zinc-iron alloy and pile up, making strip steel produce arch bag, projection, thus have a strong impact on the product quality of galvanized sheet.Thus prior art is had to the sinking roller of frequently changing dry slag, not only resulting in a large amount of of spare part consumes and the wastes of resource, and affects production, increases labor intensity.
Utility model content
This utility model is for the deficiencies in the prior art, it is provided that a kind of sinking roller, to solve problems of the prior art.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of sinking roller, it is characterized in that: include roll body and roll shaft, described roll shaft is arranged in roll body, it is provided with fixed block between described roll body and roll shaft, described fixed block is provided with projection, described roll shaft is provided with the first groove, described fixed block lower end is arranged in the first groove, described roll body is provided with the second groove, described projection is arranged in the second groove, described roll body outer surface is provided with the helicla flute of contrary rotation direction, described helicla flute includes the first helicla flute and the second helicla flute, described first helicla flute is arranged on the second spiral fluted upper end, described first helicla flute is trapezoid spiral groove, described second helicla flute is V-type helicla flute.
As a kind of improvement of the present utility model, described roll body is tubular, and its two ends external diameter is less than middle body external diameter.
Owing to have employed above technology, this utility model compared with the prior art, has the advantage that as follows:
This utility model is a kind of simple in construction, a kind of sinking roller safe and reliable, easy to use, with low cost, this utility model is provided with fixed block, can effectively prevent sinking roller meeting because of frictional force, sinking roller axle journal slipper wear damage, effectively extend the service life of sinking roller, this utility model is provided with first groove corresponding with fixed block and the second groove, can strengthen fixed block is fixed, effectively prevent fixed block to be moved；This utility model central roll external surface is provided with the helicla flute of contrary rotation direction, can quickly be flowed out by the zinc liquid on sinking roller surface, prevent zinc liquid from piling up, effectively extend the service life of sinking roller, reduce use cost；In this utility model in helicla flute, upper end is trapezoid spiral groove, and lower end is V-type helicla flute, zinc liquid can be made quickly to fall in helicla flute, thus accelerate the flowing of zinc liquid.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of sinking roller；
Fig. 2 is spiral fluted structural representation；
In figure: 1, roll body, 2, roll shaft, 3, fixed block, 4, projection, the 5, first groove, the 6, second groove, 7, helicla flute, the 8, first helicla flute, the 9, second helicla flute.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with this utility model.
Visible in conjunction with accompanying drawing, a kind of sinking roller, including roll body 1 and roll shaft 2, described roll shaft 2 is arranged in roll body 1, it is provided with fixed block 3 between described roll body 1 and roll shaft 2, described fixed block 3 is provided with projection 4, described roll shaft 2 is provided with the first groove 5, described fixed block 3 lower end is arranged in the first groove 5, described roll body 1 is provided with the second groove 6, described projection 4 is arranged in the second groove 6, described roll body 1 outer surface is provided with the helicla flute 7 of contrary rotation direction, described helicla flute 7 includes the first helicla flute 8 and the second helicla flute 9, described first helicla flute 8 is arranged on the upper end of the second helicla flute 9, described first helicla flute 8 is trapezoid spiral groove, described second helicla flute 9 is V-type helicla flute.
Described roll body 1 is tubular, and its two ends external diameter is less than middle body external diameter, and roll body 1 outer surface is to be tilted to two ends by centre, can accelerate the flowing of zinc liquid, effectively prevent roller zinc liquid in operation process to be deposited in the middle of roller.
It is provided with fixed block 3 between roll body 1 and roll shaft 2, can effectively prevent sinking roller from can effectively extend the service life of sinking roller because frictional force, dip-roll 2 neck slipper wear damage；Roll body 1 and roll shaft 2 are provided with first groove 5 and second groove 6 corresponding with fixed block 3, can strengthen fixing fixed block 3, effectively prevent fixed block 3 to be moved；Roll body 1 outer surface is provided with the helicla flute 7 of contrary rotation direction, can quickly be flowed out to two ends by centre by the zinc liquid on sinking roller surface, prevent zinc liquid from piling up, effectively extend the service life of sinking roller, reduce use cost；The upper end of helicla flute 7 is trapezoid spiral groove, and lower end is V-type helicla flute, zinc liquid can be made quickly to fall in helicla flute 7, thus accelerate the flowing of zinc liquid.
Above-described embodiment is only optimal technical scheme of the present utility model; and it is not construed as restriction of the present utility model; the technical scheme that protection domain of the present utility model should be recorded with claim; it is protection domain including the equivalents of technical characteristic in the technical scheme that claim is recorded; equivalent the most in this range is improved, also within protection domain of the present utility model.
