Description
Technical field
A kind of supporting roller bearing seat of the easy disassembly when supporting roller of straightening machine needs repairing is the utility model is related to, is belonged to
Supporting roller of straightening machine equipment technical field.
Background technology
Withdrawal straightening machine is key equipment during Rolling production, and for improving Flatness of Hot Rolled Strip, it is bent to eliminate strip shape wave, wooden dipper
Deng flatness defect, the glacing flatness and strip shape quality of strip are improved, while improves hot-strip and breaks phosphorus effect, makes strip surface oxidation
Iron sheet crushes, and improves pickling efficiency.Withdrawal straightening machine roll system structure is made of two sets of bending units and a set of resistance straightening unit, shares five groups
Roller box, each group of roller box amount to 9 pairs by a working roll and two row（18）Support roller forms.Due to support roller roller, system is with two
Branch roller forms in series for one group, if the support roller that there is damage in roller system middle part needs replacing, by assembly technology
Limited, when replacement can only dismantle successively from side, adds workload, reduces efficiency.When new roller returns dress, it is necessary to new roller with
Old bearing block will carry out reconditioning, be equipped with, and can not ensure to reach the assembly precision required by technique so that support roller easily produces axis
To displacement, cause working roll axial float big, working roll " locking " phenomenon easily occurs, so that cold-rolling process can be caused
It is unstable, bring serious economic loss to enterprise.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of supporting roller of straightening machine bearing of dismounting easy to repair
Seat, this supporting roller bearing seat can quickly, precisely complete supporting roller of straightening machine dismounting, avoid supporting roller of straightening machine from producing axial
Displacement, produces the failure of pulling correcting machine working roller axial float, and then avoids that working roll " locking " phenomenon occurs, and ensures the steady of production
It is fixed to carry out.
Solving the technical solution of above-mentioned technical problem is：
A kind of supporting roller of straightening machine bearing block of dismounting easy to repair, it is by support roller top chock and support roller lower bearing
Seat composition, support roller top chock and support roller step have a semicircle axis hole of two same diameters respectively, in support roller
The semicircle axis hole of bearing block and support roller step two complete support roller axis holes of opposite composition respectively, axis in support roller
Two support roller shaft hole diameters of bearing and support roller step composition match with support roller diameter, support roller top chock
There is opposite bearing block mounting hole respectively with the both ends of support roller step, fixing bolt will be supported through bearing block mounting hole
Roller top chock and support roller step are with drawing bridge machine roller-way to be fixedly connected.
The supporting roller of straightening machine bearing block of above-mentioned dismounting easy to repair, the support roller top chock and support roller lower bearing
There are three location holes respectively in the opposite plane of seat, three location holes are located at support roller top chock and support roller lower bearing respectively
Between seat both ends and two support roller axis holes, positioning pin is smart by support roller top chock and support roller step through location hole
Determine position.
The supporting roller of straightening machine bearing block of above-mentioned dismounting easy to repair, two semicircle axis of the support roller step
There is location hole in hole centre position respectively, and positioning pin is opposite with the support roller after installation through location hole.
The beneficial effects of the utility model are：
Original solid box holder structure is changed to the split bearing block of opposite opened by the utility model, when each group of discovery
When abnormal conditions occurs in any a set of support roller in roller box, pointedly the bearing block of the support roller can be dismantled,
The other intact support rollers of dismounting and bearing block are avoided, realizes fast assembling-disassembling and the maintenance of supporting roller of straightening machine.
The utility model is simple in structure, easy to use, the accurate positioning of support roller top chock and support roller step,
Fit precision is high, effectively prevent the damage that roller system intact parts are caused during dismounting, accident rate reduces 90%, reduces standby
Product spare parts consumption, has saved cost.Every group of support roller disassembly efficiency was reduced to for 8 man-hours from original 48 man-hour, was adapted to give birth in cold rolling
Producing line promotes and applies.

Embodiment
Original solid box holder structure is changed to the split bearing block of opposite opened, split type bearing block by the utility model
It is made of support roller top chock 1, support roller step 2.
Shown in figure, support roller top chock 1 and support roller step 2 have the semicircle axis of two same diameters respectively
The semicircle axis hole 3 of hole 3, support roller top chock 1 and support roller step 2 is opposite respectively to form two complete support rollers
Two support roller shaft hole diameters that axis hole, support roller top chock 1 and support roller step 2 form are with supporting roller diameter phase
Match somebody with somebody.
Shown in figure, there is opposite bearing block installation at the both ends of support roller top chock 1 and support roller step 2 respectively
Hole 4, fixing bolt is through bearing block mounting hole 4 by support roller top chock 1 and support roller step 2 with drawing bridge machine roller-way to consolidate
Fixed connection., can be with specific aim to the support roller when finding that abnormal conditions occurs in any a set of support roller in actual use
Support roller top chock 1 and support roller step 2 dismantled, and without dismantling other bearing blocks.
Shown in figure, support roller top chock 1, support roller step 2 opposite plane on have three location holes respectively
5, three location holes 5 respectively positioned at support roller top chock 1 and 2 both ends of support roller step and two support roller axis holes it
Between, support roller top chock 1 and support roller step 2 are accurately positioned by positioning pin through location hole 5, have been reached in support roller
The high requirement of 2 accurate positioning of bearing block 1 and support roller step, fit precision.
Shown in figure, also there be location hole 5 in two semicircle axis hole centre positions of support roller step 2 respectively, fixed
Position pin is through location hole 5, and it is opposite with the support roller after installation not submerge location hole 5, avoids after support roller is installed and occurs
Axial float.
After the utility model is implemented, the dismounting of roll bearing seat can be supported with specific aim, is convenient for changing any portion of roller system
The bad support roller of bit loss.By to support roller top chock 1 and the increase assembling location hole 5 of support roller step 2, it can be ensured that branch
Roller top chock 1 and the high requirement of 2 accurate positioning of support roller step, fit precision are supportted, while in support roller step 2
Two semicircle axis hole centre positions increase location holes, positioning pin is opposite with the support roller after installing through location hole 5, avoids
The axial float occurred after support roller installation.The utility model is very big using playing the role of to cold rolling straightening device stabilization, compared with
Solves the bottleneck problem in supporting roller of straightening machine assembling process well.
