Description
Technical field
The utility model relates to the conveying roller that uses on a kind of rolling line, especially a kind of combination transfer roller.
Background technology
Usually, the running orbit of rolled piece is fixed on the rolling line, and the abrading section of rolled piece conveying roller is also fixing, and the worn-down conveying roller can cause surface quality defects such as backfin to a large amount of rail.
To the conveying roller of present integral type solid construction, the mode that solves the conveying roller wear problem is nothing more than three kinds: optimize conveying roller material, laser surface treatment, artificial weld deposit repairing.It is modal mode that the conveying roller fray is carried out artificial weld deposit repairing, treats to carry out repair welding when the abrading section degree of depth reaches 15mm～20mm, if quality of welding repair is poor, the conveying roller after the soldering is frequent scratch rolled piece also; In addition, because the time-consuming length of soldering, in maintenance, maintenance intervals, most conveying roller can't obtain actv. and safeguard that maintenance effects is undesirable, and a large amount of rolled pieces is caused surface quality defect, want the maintenance effects that reaches desirable, can impact the normal production cycle again, be difficult to satisfactory to both parties.In addition, the general employed conveying roller barrel length of rolling line is much wideer than the rolled piece width, even take all factors into consideration rolled piece out-of-position situation, actual greatest wear width also is the small part of conveying roller barrel length, if delay the conveying roller wearing and tearing to optimize conveying roller material or laser surface treatment, waste is largely arranged, increased unnecessary cost.
The utility model content
In order to overcome the deficiency of existing rolled piece rollgang maintenance expense duration, technical problem to be solved in the utility model provides a kind of combination transfer roller of being convenient to safeguard and safeguard the time spent weak point.
The technical scheme that its technical matters that solves the utility model adopts is: the combination transfer roller, comprise roll shaft, and described roll shaft outside is with one section collars that removably connects with roll shaft.
Described collars is formed by two bearing shell spellings.
One end of described bearing shell is positioned at the annular positioning groove that is provided with on the roll shaft, and the other end of bearing shell is fixed by the baffle ring that is connected on the roll shaft, and each bearing shell is connected with the roll shaft key.
Described baffle ring end is provided with groove, and described bearing shell two ends respectively are provided with boss, cooperates with described groove and described annular positioning groove inclined-plane respectively.
Described baffle ring is threaded with roll shaft.
The beneficial effects of the utility model are: by the collars that overcoat is set in the conveying roller abrading section, solve conveying roller surface abrasion problem, both saved the roller consumption, can improve the rolled piece surface quality again, effectively raise the service efficiency of conveying roller, shortened the upkeep operation time greatly, and reduced maintenance cost greatly.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1～shown in Figure 10, combination transfer roller of the present utility model comprises roll shaft 1, and described roll shaft 1 outside is with one section collars 3 that removably connects with roll shaft 1.The length of considering conveying roller actual wear section is generally shorter with respect to whole barrel length, therefore, the utility model utilize one section be enclosed within that roll shaft 1 exterior collars 3 bears and rolled piece between frictional loss, simultaneously, removably connect between collars 3 and the roll shaft 1, behind severe wear, can change the collars 3 of same specification quickly and easily, shorten safeguarding the time spent of conveying roller, influence of rolled Production Line cycle not, simultaneously, collars is carried out material optimization or cost is more saved in surface treatment, can guarantee the rolling quality of rolled piece equally.
As Fig. 1 and Fig. 8, Fig. 9, shown in Figure 10, for make, easy for installation, described collars 3 should adopt split-type structural, generally collars 3 can be decomposed into by two bearing shell 5 spellings to form.
As figure～shown in Figure 10, in order to ensure the axial restraint of bearing shell and radially fixing, make Assembly ﹠Disassembly convenient simultaneously, annular positioning groove 6 can be set on roll shaft 1, one end of described bearing shell 5 snaps fit onto earlier in this annular positioning groove 6, the other end of bearing shell 5 is fixing by the baffle ring 2 that is connected on the roll shaft 1 again, for avoiding the dynamic friction under in working order of bearing shell 5 and roll shaft 1 to cause unnecessary roller consumption, on bearing shell 5, be provided with keyway 9, and the keyway 8 that is complementary is set on the roll shaft 1, bearing shell 5 is connected by key 4 with roll shaft 1.
For further satisfying the operating mode of conveying roller, described baffle ring 2 ends are provided with groove 7, described bearing shell 5 two ends respectively are provided with boss 51,52, cooperate with described groove 7 and described annular positioning groove 6 inclined-planes respectively, further utilize the static friction on boss 51,52 surfaces to prevent dynamic friction under bearing shell 5 and roll shaft 1 are in working order, simultaneously, the inclined-plane cooperation also has the axial location effect, avoids bearing shell 5 to be subjected to displacement on roll shaft 1.
Consider easy to assemblyly, described baffle ring 2 can be threaded with roll shaft 1, and can be on baffle ring 2 radial hole that screws operation easy to process.
Embodiment:
The the 1st, the 2nd, the 3 three conveying roller behind the U1 milling train machine of certain universal rolling line is replaced by compound type conveying roller of the present utility model compares test.
After producing rolling 15 days, compound type conveying roller and other conveying roller wearing depth reach the degree of depth of 20mm, during the compound type conveying roller run well no abnormal phenomenon.
Collars on the 1st, the 2nd, the 3 three conveying roller behind the U1 machine is changed, as a comparison three existing integrated solid conveying rollers are then carried out artificial built-up welding soldering.
Through on-the-spot timing:
The time of changing behind the U1 machine collars on the 1st, 2, the 3 compound type conveying roller is respectively: 10min, 9.5min, 10.2min, total time are 29.7min.The time of carrying out artificial built-up welding soldering to 3 solid conveying rollers is respectively: 40min, 45min, 41min, total time is: 126min.As seen, the compound type conveying roller is changed the time of collars less than 1/4 of the former repairing time, the effect highly significant.
Estimate, after will having conveying roller now and all being replaced by the compound type conveying roller, can reduce the time that takies the very large soldering conveying roller of ratio in maintenance, the maintenance intervals, the operating rate of saving manually and actv. is improved this universal rolling line greatly.
