Description
Technical field
A kind of alignment roller of Rolling production is the utility model is related to, belongs to roller bed equipment technical field.
Background technology
In Rolling production, on finished steel after cold bed, alignment roller table is progressively reached by cold bed stepping, first arrival pair
The finished steel of neat roller-way is fed forward by alignment roller table, at the same with cold bed stepping continue it is traversing by alignment roller table, so
Finished steel advances on the traversing side in alignment roller table top, is blocked when proceeding to cold bed end fixed dam by baffle plate, before stopping
Enter.The finished steel to halt only moves laterally, and every finished steel successively reaches baffle plate by this motor program and stopped
Advance, reach the purpose of alignment.
For steel when being conveyed on alignment roller table, the power for promoting steel to advance is the frictional force between drive roll and steel,
When producing screw-thread steel, because reinforcing bar horizontal bar rib presence can increase frictional force.During the use of alignment roller, due to steel
Continuous with alignment roller contacts, and particularly in rolled threaded steel, the roll surface of alignment roller can wear, after wearing, shadow
The alignment effect of steel is rung, so needing often to change alignment roller.The alignment roller worn can be carried out scrapping processing or carried out
Repair, directly scrap processing and considerably increase the production cost of enterprise, therefore the alignment roller of abrasion is repaired and usually looked forward to
The first choice of industry, to reduce the production cost of enterprise.
Because existing alignment roller is overall structure, the restorative procedure taken at present is the portion to abrasion by bead-welding technology
Divide and carry out repair welding, be then machined out repairing roll surface.But because alignment roller diameter is smaller, by the shadow of weld deposit process high temperature
Ring, the metabolies such as alignment roller easily bends in weld deposit process so that repairing failure.For this reason, it is necessary to existing right
Design is optimized in neat roller, can effectively to be repaired after wearing in alignment roller, extends alignment as much as possible
The reuse number of roller.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of steel rolling alignment roller being easily repaired, this alignment roller
Using split-type structural, it can easily be repaired upon wear, extend the service life of alignment roller, reduce the production of enterprise
Cost, improve the economic benefit of enterprise.
Solve above-mentioned technical problem technical scheme be：
A kind of steel rolling alignment roller being easily repaired, it includes mandrel, roll body, baffle ring, locknut, and roll body is by multiple annular rollers
Composition, the diameter of bore of roller and the external diameter of mandrel match, and roller is enclosed on mandrel, and the outer circumferential walls of roller are the work of roll
Make roll surface, baffle ring is multiple annulus, and the diameter of bore of baffle ring and the external diameter of mandrel match, and the outer circumference diameter of baffle ring is more than roller
Outer circumference diameter, baffle ring is enclosed on mandrel, multiple rollers and the spaced placement of multiple baffle rings, and locknut is arranged on one end of mandrel
By roller and baffle ring axial restraint.
There is a shaft shoulder the above-mentioned steel rolling alignment roller being easily repaired, one end of the mandrel, and the baffle ring on the outside of roller leans against the shaft shoulder
On, the other end of mandrel has screw thread, and the internal thread of locknut and the screw thread of mandrel match, and mandrel thread end is set with axle sleeve, axle
It is closely relative with the baffle ring on the outside of roller and locknut respectively to cover both ends.
The beneficial effects of the utility model are：
Alignment roller is designed as split-type structural by the utility model, and roll body is sleeved on mandrel, and roll body is by multiple roller groups
Into the roller for having abrasion to roll surface after alignment roller can be dismantled after use after a while is repaired.The utility model
Simple in construction, installation and removal conveniently, can individually be repaired to abrading section, avoid the tired of overall reparation alignment roller
Difficulty, reduce and repair difficulty and maintenance cost.The utility model can quickly and easily be changed to the alignment roller after abrasion
And reparation, roll body may be reused, the use cost of alignment roller can be effectively reduced.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is repair process schematic diagram of the present utility model.
Marked in figure as follows：Mandrel 1, roll body 2, roller 3, baffle ring 4, locknut 5, axle sleeve 6, reparation mandrel 7, chuck 8, top
Point 9, tip 10.
Embodiment
The existing overall roll structure that aligns is changed to split-type structural by the utility model, to be directed to abrading section
Repair.Alignment roller after improvement is made up of mandrel 1, roll body 2, roller 3, baffle ring 4, locknut 5, axle sleeve 6.
Fig. 1 shows that roll body 2 is made up of multiple annular rollers 3, and the external diameter of the diameter of bore and mandrel 1 of roller 3 matches,
Roller 3 is enclosed on mandrel 1, and the outer circumferential walls of roller 3 are the work roll surface of roll., can because roll body 2 uses multiple segmental structures
Individually repaired with the part to abrasion, avoid the difficult and inconvenient of overall reparation alignment roller.
Fig. 1 shows that baffle ring 4 is multiple annulus, and the external diameter of the diameter of bore and mandrel 1 of baffle ring 4 matches, outside baffle ring 4
All diameters are more than the outer circumference diameter of roller 3, and multiple roller 3 and multiple baffle rings 4 spacer sleeves are mounted on mandrel 1,
Fig. 1 shows that there is the shaft shoulder one end of mandrel 1, and the baffle ring 4 in the outside of roller 3 is leaned against on the shaft shoulder, and the other end of mandrel 1 has
Screw thread, the screw thread of the internal thread and mandrel 1 of locknut 5 match, and the end of thread of mandrel 1 is set with axle sleeve 6, the both ends of axle sleeve 6 respectively with
The baffle ring 4 and locknut 5 in the outside of roller 3 are closely relative.Locknut 5 is arranged on one end of mandrel 1 by roller 3 and the axial restraint of baffle ring 4.
In use for some time, the outer surface of roll body 2 can wear alignment roller, the abrasion of the roller 3 of diverse location
Degree makes a big difference, and can be repaired to wearing more serious roller 3, wearing slight roller 3 can continue to make
With.
Fig. 2 shows that repair process of the present utility model is as follows：
First, split type alignment roller is dismantled, the order of roller 3 of serious wear is sleeved on reparation mandrel 7, repaiied
It is identical with work mandrel 1 to be multiplexed the structure of mandrel 7, multiple rollers 3 are fixed on mandrel 6 by locknut 5.
Secondly, the mandrel 7 after suit roller 3 is fixed on built-up welder, completes to wear roller 3 by way of built-up welding
Repair outer surface.
After built-up welding, reparation mandrel 7 is placed on lathe, repair clamped respectively with chuck 8 with the both ends of mandrel 7 and
Held out against with top 9, Surface Machining is carried out to the roller 3 of heap postwelding with lathe.Roller 3 after completion of processing may be reused,
Because built-up welding is passed through in the outer surface of roller 3, case hardness increases, and wearability is good, it is ensured that the online long period of alignment roller
Use.
