Abstract
A kind of cantilever furnace roller, comprise roll shaft, stop nut, described roll shaft left end is arranged with roller, and roller is fastened on roll shaft by stop nut, and roller right-hand member is located by the preset pieces be welded on roll shaft, and roll shaft left end is welded with silently in hole.The utility model is rational in infrastructure, is convenient to repair, and improves work-ing life, reduces production cost.
Description
Technical field:
The utility model relates to a kind of parts of steel rolling continuous annealing furnace, refers more particularly to a kind of cantilever furnace roller.
Background technology:
In metallurgical industrial furnace, metal pipe material, bar adopts furnace roller to carry in continuous annealing furnace, carrying, at present, furnace roller on market is by the body of roll, roll neck, spindle nose formed, roll neck is welded on spindle nose, body of roll two ends are welded on two roll necks, in order to ensure the mechanical property of furnace roller, therefore the furnace roller body of roll, roll neck material all employ Langaloy, except controlling the chemical composition of material, to working accuracy, weldprocedure, detect to wait and all carried out strict control, but in actual use, there is the body of roll and roll neck welding seam failure cracking, very cause the phenomenon of disengaging, whole furnace roller cannot be used, cause the waste of material, add the labour intensity of maintenance cost and workman.
Summary of the invention:
The purpose of this utility model is to provide a kind of rational in infrastructure, is convenient to repair, and can improve work-ing life, reduce the cantilever furnace roller of production cost.
The purpose of this utility model is achieved in that a kind of cantilever furnace roller, comprise roll shaft, stop nut, it is characterized in that: described roll shaft left end is arranged with roller, roller is fastened on roll shaft by stop nut, roller right-hand member is located by the preset pieces be welded on roll shaft, and roll shaft left end is welded with silently in hole.
Described roll shaft left end is provided with the Rolls Position shaft shoulder.
Described stop nut adopts the mode of connection of welding with roller.
Described stop nut adopts the mode of connection of welding with roll shaft.
Described preset pieces is set to four, and uniform vertical is welded on roll shaft, drives roller to rotate.
Described roll shaft is set to tubular shaft.
The utility model is rational in infrastructure, is convenient to repair, and improves work-ing life, reduces production cost.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
In figure 1, roll shaft, 3, preset pieces, 4, roller, 6 silently, 7, stop nut.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, a kind of cantilever furnace roller, comprises roll shaft 1, stop nut 7, it is characterized in that: described roll shaft 1 left end is arranged with roller 4, roller 4 is fastened on roll shaft 1 by stop nut 7, and roller 4 right-hand member is located by the preset pieces 3 be welded on roll shaft 1, is welded with silently 6 in roll shaft 1 left end hole.Described roll shaft 1 left end is provided with the Rolls Position shaft shoulder.Described stop nut 7 adopts the mode of connection of welding with roller 4.Described stop nut 7 adopts the mode of connection of welding with roll shaft 1.Described preset pieces 3 is set to four, and uniform vertical is welded on roll shaft 1, drives roller 4 to rotate.Described roll shaft 1 is set to tubular shaft.
During concrete enforcement, first on roll shaft, four preset pieces uniform vertical are welded on roll shaft, from roll shaft left side cover upper roller, four grooves of roller right side are stuck on four preset piecess, after tightening by stop nut, by nut and roll shaft and roller welding, prevent nut loosening; By silently welding together with roll shaft in roll shaft hole, water-cooled tube is installed in hole and carries out circulating cooling.The utility model in use, difficult drop-off, cracking, long service life, once welding seam failure cracking, whole furnace roller can not be made to use, again can continue after welding to use, there will not be the phenomenon of bearing seizure, the waste of material can not be caused, fall and lacked maintenance cost.
