Description
Technical field:
The utility model belongs to steel making equipment technical field, and in particular to a kind of extension shaft for rolling mill support roller device.
Background technique:
There are biggish hidden trouble of equipment during the practical spindle of production for mill drive axis, and spindle is difficult, affects life
Roll change activity time is produced, reduces efficiency, while increasing maintenance worker's labor intensity, increases spare parts cost.So designing one kind
Convenient for roll change and the extension shaft for rolling mill support roller device that can reduce maintenance cost is very necessary.
Utility model content:
The purpose of the utility model is to provide a kind of convenient for roll change and can reduce the extension shaft for rolling mill support of maintenance cost
Roller arrangement guarantees the stability of spindle by the position of support roller device abutment shaft and the design of roll profile, easy to operate,
Labor intensity is reduced, efficiency is improved, reduces maintenance of equipment cost, securely and reliably, manufacturing cost is cheap, and it is economic and practical,
It is easy to promotion and application on a large scale.
The technical solution adopted in the utility model are as follows: a kind of extension shaft for rolling mill support roller device, the support roller device include
Roller, roll shaft, end cap, bearing and axle bed；The roller is mounted on roll shaft by bearing, and the end cap is mounted on by bolt
Roller both ends, the roll shaft are mounted on axle bed.
Further, the outer profile section of the roller is V-shaped, and roller is equipped with ladder axis hole, and roller both ends are equipped with
The connection screw thread hole of circumference uniform distribution.
Further, the V word angle in the V-shaped outer profile section of the roller is 146 degree.
Further, the end cap is equipped with the mounting hole of circumference uniform distribution, is equipped with convex edge on the inside of end cap.
Further, the axle bed is equipped with connecting hole.
A kind of convenient for roll change and it can reduce the extension shaft for rolling mill branch of maintenance cost the utility model has the beneficial effects that providing
Roller arrangement is supportted, upgrading adjustment is carried out by the position of support roller device abutment shaft, guarantees the stability of spindle, easy to operate, drop
Low labor intensity, improves efficiency, reduces maintenance of equipment cost, and securely and reliably, structure is simple, design rationally, manufacture at
This is cheap, economic and practical, is easy to promotion and application on a large scale.

Specific embodiment:
Embodiment one
Referring to each figure, a kind of extension shaft for rolling mill support roller device, the support roller device include roller 1, roll shaft 2, end cap 3,
Bearing 4 and axle bed 5；The roller 1 is mounted on roll shaft 2 by bearing 4, and the end cap 3 is mounted on 1 liang of roller by bolt
End, the roll shaft 2 are mounted on axle bed 5；The outer profile section of the roller 1 is V-shaped, and roller 1 is equipped with ladder axis hole 13,
1 both ends of roller are equipped with the connection screw thread hole 12 of circumference uniform distribution；The V word angle in the V-shaped outer profile section of the roller 1 is 146
Degree；The end cap 3 is equipped with the mounting hole 31 of circumference uniform distribution, is equipped with convex edge 32 on the inside of end cap 3；The axle bed 5 is equipped with connection
Hole 51；The axle bed 5, which is bolted, to be fixed on roller pedestal.Roll profile and overall structure form are improved, is guaranteed de-
The stability of axis.Improved extension shaft for rolling mill device, existing hidden trouble of equipment before eliminating equipment, while substantially reducing worker
Labor intensity reduces maintenance of equipment cost, while improving production roll change activity time.
Support roller before transformation, roller opening degree is big, during producing spindle, can not accurately connect in place, often
Secondary to add sleeper to support spindle every time by post work, there are severe compromises during connection；In addition front support roller is transformed
Assembly, copper sheathing rapid wear, while the frequent card resistance of roller, are rotated by post work using crowbar, there are severe compromises.Pass through
Redesign roll profile and overall structure form, guarantee de- axis stability and by the position of support roller device abutment shaft into
Row upgrading adjustment, guarantees the stability of spindle, completes the entire process of production replacement mill rolls in this way, while eliminating equipment
Existing security risk.
