Abstract
The present invention provides a kind of air-cooled roller-way on-line maintenance method of wire rod, and step is as follows：The bearing block at air-cooled roller-way journal wear position is removed, using cutting of cutting knife except abrasion axle journal, and leaves reserved axle journal；The face of cutting off for reserving axle journal is polished using sanding machine；Neck bush is attached on reserved axle journal, electric welding reinforcing is carried out after being installed in place；Electric welding knocks out the dregs of a decoction after reinforcing, and new bearing block is attached on neck bush；Pedestal base is positioned over below new bearing block, loads flat key, new bearing block is fastened using bolt.The present invention instead of the maintenance mode for changing whole roller-way, and maintenance mode is more simple, more easy to operate；Repeatedly same position can be changed；The continuity of production has been ensured while maintenance personal's labor intensity is reduced, has improved production efficiency.
Description
Technical field
The invention belongs to maintenance technology field, and in particular to a kind of air-cooled roller-way on-line maintenance method of wire rod.
Background technology
High-speed rod coils the air-cooled important ring as quality after Laying head is gone out, and decision is played to the performance of product
The influence of property.The country is generally using by an active roller-way at present（Motor drives）Driven by sprocket wheel, chain some
Driven roll, so as to realize the movement of coiling, blower fan is provided with the lower section of roller-way, changes the property of product by controlling air quantity
Can, the requirement of client is finally reached, this technology has tended to be ripe.And for roller-way itself, its both ends is using axle
Bearing（Include bearing, referred to hereinafter as bearing block）It is fixed, using key connection between bearing and roller-way axle journal, used with online
The axle journal surface wear with bearing touch certainly will occurs so as to cause roller-way to rock in the lengthening of time, for a long time in the feelings of insufficient lubrication
It can even cause axle journal to be broken under condition, have a strong impact on the production order.In order to avoid it is such the occurrence of, can only use to axle journal
The roller-way of abrasion carries out the maintenance mode of offline replacing, and it is relatively complicated to change whole roller-way step, while in maintenance process
The potential safety hazard of lifting operation be present.
Therefore, the maintaining method for a kind of air-cooled roller-way of wire rod being developed to solve problem above is those skilled in the art
Institute's urgent need to solve the problem.
The content of the invention
In order to solve the above problems, the present invention provides a kind of air-cooled roller-way on-line maintenance method of wire rod.
In order to achieve the above object, the present invention provides following technical scheme：
A kind of air-cooled roller-way on-line maintenance method of wire rod, step are as follows：
（1）The bearing block at air-cooled roller-way journal wear position is removed, using cutting of cutting knife except abrasion axle journal, and leaves reserved axle journal；
（2）The face of cutting off for reserving axle journal is polished using sanding machine；
（3）Neck bush is attached on reserved axle journal, electric welding reinforcing is carried out after being installed in place；
（4）Electric welding knocks out the dregs of a decoction after reinforcing, and new bearing block is attached on neck bush；
（5）Pedestal base is positioned over below new bearing block, loads flat key, new bearing block carried out using bolt tight
Gu.
Preferably, step（1）In reserve axle journal length be 1~3cm.
Preferably, step（1）Middle cutter is welding knife.
Preferably, step（2）Middle polishing, which need to be polishing to, cuts off face impulse- free robustness.
Preferably, step（4）The middle knockout dregs of a decoction need to be knocked out to the full no rosin joint of weld seam, cracking phenomena.
Preferably, step（5）In bolt be M12 bolts.
Preferably, step（1）In reserve axle journal length be 2cm.
Preferably, step（5）It is middle new bearing block is fastened using bolt before also need position to air-cooled roller-way
Put and be adjusted.
The present invention compared with prior art, instead of the maintenance mode for changing whole roller-way, maintenance mode is more simple, more
It is easy to operate；Repeatedly same position can be changed；The continuous of production has been ensured while maintenance personal's labor intensity is reduced
Property, improve production efficiency.
Brief description of the drawings
Fig. 1, the air-cooled roller-way of middle wire rod of the invention structural representation；
The air-cooled roller-way of wire rod cuts off the structural representation after abrasion axle journal in Fig. 2, the present invention；
Structural representation after the air-cooled roller-way of wire rod is safeguarded in Fig. 3, the present invention.
Embodiment
Technical scheme provided by the invention is described in detail below with reference to specific embodiment, it should be understood that following specific
Embodiment is only illustrative of the invention and is not intended to limit the scope of the invention.
A kind of air-cooled roller-way on-line maintenance method of wire rod, step are as follows：
（1）Such as Fig. 1, the bearing block at the air-cooled journal wear position of roller-way 1 is removed, cuts off abrasion axle journal using welding knife, and leave
Such as Fig. 2 reserved axle journal 2, the length for reserving axle journal 2 is 2cm.
（2）The face of cutting off for reserving axle journal 2 is polished using sanding machine, until cutting off face impulse- free robustness；
（3）Such as Fig. 3, neck bush 3 is attached on reserved axle journal 2, electric welding reinforcing is carried out after being installed in place；
（4）Electric welding knocks out the dregs of a decoction after reinforcing, until the full no rosin joint of weld seam, cracking phenomena, and new bearing block 4 is installed
To neck bush 3；
（5）Pedestal base 5 is positioned over to the new lower section of bearing block 4, loads flat key, the position of air-cooled roller-way is adjusted,
New bearing block 4 is fastened using M12 bolts.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned embodiment, in addition to
Formed technical scheme is combined by above technical characteristic.
