Description
Technical field
The utility model relates to a kind of specific purpose tool removing hot straightening machine supporting roller bearing, belongs to thermal straightening machine maintenance of equipment technical field.
Background technology
In steel plate rolling is produced, the effect of thermal straightening machine is aligned steel plate.The straightening operation parts of thermal straightening machine are upper and lower roll systems, and upper and lower roll system is made up of roller box, backing roll and working roll respectively, and upper roller system has 32 backing rolls and 4 working rolls, and there are 32 backing rolls and 5 working rolls in lower roll system.Every root backing roll is fitted with two cover sealings and two cover bearings, after a certain period of use time, and sealing meeting Natural Damage, but back-up roll bearing still can use.Needing when changing sealing to remove bearing, owing to lacking the instrument of special dismounting back-up roll bearing at present, therefore can cause bearing damage in various degree in demolishing process.The upper and lower roll system of a thermal straightening machine uses 128 cover sealings and 128 cover bearings altogether, if the intact of bearing can be kept when changing sealing as far as possible, enabling bearing continue to use, will a large amount of bearing spare parts be saved, reduce maintenance cost, be therefore necessary to improve existing dismounting bearing mode.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of instrument removing hot straightening machine supporting roller bearing, this instrument can reasonably remove hot straightening machine supporting roller bearing, bearing is avoided to damage in unloading process, ensure that dismounting rear bearing can continue to use, to reduce maintenance cost and production cost.
The technical scheme solved the problems of the technologies described above is:
A kind of instrument removing hot straightening machine supporting roller bearing, it comprises hydraulic jack, top board, connecting bolt, high pressure lubricator, top board is circular steel plate, the plate face of top board is relative with the end face of backing roll, connecting bolt is 3-4 bar, 3-4 bar connecting bolt is around backing roll circumference uniform distribution, the lower end of connecting bolt is connected with bearing gland, the upper end of connecting bolt is connected with top board circumference, the base of hydraulic jack is placed on the end face of backing roll, the push rod of hydraulic jack withstands on the lower surface center of top board, the oil fuel tube of high pressure lubricator is connected with bearing oil.
The instrument of above-mentioned dismounting hot straightening machine supporting roller bearing, described connecting bolt is 4, and 4 connecting bolts are uniform around the backing roll circle spacing 90 degree.
The beneficial effects of the utility model are:
Connecting bolt of the present utility model is connected top board with bearing gland, hydraulic jack is placed between top board and bearing gland, high pressure lubricator is connected with bearing oil, bearing inner race swell is made after high pressure lubricator oiling, utilize hydraulic jack jack-up top board, top board drives bearing gland and bearing to move, and finally bearing is extracted.The utility model structure is simple, easy to use, can not cause damage to bearing, and what greatly reduce bearing scraps quantity, has saved the expense of spare part, has reduced production cost, improve the economic benefit of enterprise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: hydraulic jack 1, connecting bolt 2, top board 3, bearing 4, bearing gland 5, high pressure lubricator 6, backing roll 7.
Detailed description of the invention
The utility model is made up of hydraulic jack 1, connecting bolt 2, top board 3, high pressure lubricator 6.
Show in figure, top board 3 is circular steel plate, and the plate face of top board 3 is relative with the end face of backing roll 7.The top board 3 of an embodiment of the present utility model adopts the steel plate of 300mm × 300mm × 20mm.
Show in figure, connecting bolt 2 is 4, and 4 connecting bolts 2 are uniform around backing roll 7 circle spacing 90 degree, and the lower end of connecting bolt 2 is connected with bearing gland 5, and the upper end of connecting bolt 2 is connected with top board 3 circumference.Connecting bolt 4 M16 × 320 bolts of an embodiment of the present utility model.
Show in figure, hydraulic jack 1 is located between top board 3 and bearing gland 5, the base of hydraulic jack 1 is placed on the end face of backing roll 7, the push rod of hydraulic jack 7 withstands on the lower surface center of top board 3, in hydraulic jack 1 action, the push rod of hydraulic jack 1 is by top board 3 upwards jack-up, and top board 3 drives bearing gland 5 to move up, thus band dynamic bearing 4 is upwards extracted.
Show in figure, the oil fuel tube of high pressure lubricator 6 is connected with bearing oil.During dismounting bearing 4, by bearing oil, oiling is carried out to bearing inner race with high pressure lubricator 6, make bearing inner race swell, decline with the tightness degree that coordinates of backing roll 7 circumference after bearing inner race swell, can avoid when at this moment driving bearing gland 5 to be extracted by bearing 4 by hydraulic jack 1 because bearing inner race coordinates closely with backing roll 7 and damage.
After using the utility model to remove hot straightening machine supporting roller bearing, what greatly reduce bearing scraps quantity, has saved the expense of spare part, has reduced production cost, improve the economic benefit of enterprise.
