Abstract
The utility model provides a change sealed device of finish rolling roll change pneumatic cylinder piston at machine, its device includes that the jar pole extends a section of thick bamboo, double-end long stud, nut, clamp plate. The method is to screw the double-end long stud bolt to the exposed head part of the cylinder rod; sleeving a cylinder rod extension cylinder on a cylinder rod, sleeving a pressing plate on a long stud and fixing the pressing plate by using a nut; adjusting the cylinder rod extending cylinder to be integrated with the cylinder rod, and tightening the nut at the moment; the joint of the cylinder rod extension cylinder and the cylinder rod is polished by fine sand paper and oilstone, so that burrs of a scraping hand are not needed, and the front seal of the hydraulic cylinder is prevented from being damaged during retraction; and opening the rear cover of the hydraulic cylinder, slowly ejecting the cylinder rod from front to back, and replacing the piston seal after the piston is completely exposed. Compared with the prior art, the beneficial effects of the utility model are that: the operation is simple, the used time is short, the hydraulic cylinder body does not need to be disassembled and assembled, the spare part cost is greatly saved, the accident handling time is reduced, and the effect after the operation is good.
Description
Technical field
The utility model relates to hot continuous rolling plant equipment, particularly a kind of device changing finish rolling roll change sealing piston of hydraulic cylinder at machine.
Background technology
Finish rolling roll change hydraulic cylinder is a vitals in mm finishing mill unit roll changing system, within approximately every 6 hours, will use once, push-and-pull weigh about 10 tons working roll turnover frame.Vibrations, the reason such as aging can cause finish rolling roll change hydraulic cylinder sealing often to damage.In hot continuous rolling production line, finish rolling roll change hydraulic cylinder is positioned at below finish rolling operating desk, whole hydraulic cylinder is often needed to disassemble during replacing, and it is carried out below finish rolling operating desk change, because cylinder body is huge heavy, therefore very inconvenient, the whole disassembly process that operates wastes time and energy, and often produces the very long activity duration.Whole cylinder body to be changed simultaneously, too increase maintenance cost.
Utility model content
The purpose of this utility model is to provide a kind of device changing finish rolling roll change sealing piston of hydraulic cylinder at machine, device is simple to operate, time less used, maximum advantage does not need dismounting cylinder body, greatly save spare part expense, decrease the accident treatment time, and respond well after operation.
For achieving the above object, the utility model realizes by the following technical solutions:
For changing the device of finish rolling roll change sealing piston of hydraulic cylinder at machine, comprise cylinder bar exntension tubs, double end long threaded rod, nut, pressing plate, described double end long threaded rod is screwed into finish rolling roll change hydraulic cylinder club head, cylinder bar exntension tubs are enclosed within the outside of cylinder club head and double end long threaded rod, pressing plate is buckled in the end of cylinder bar exntension tubs through double end long threaded rod, and pressing plate and cylinder bar exntension tubs and cylinder bar are fixed by nut driving on double end long threaded rod.
Compared with prior art, the beneficial effects of the utility model are:
This device is simple to operate, time less used, and maximum advantage does not need dismounting cylinder body, greatly saved spare part expense, decreases the accident treatment time, and respond well after operation.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 8, Fig. 9, Figure 10, for changing the device of finish rolling roll change sealing piston of hydraulic cylinder at machine, comprise cylinder bar exntension tubs 3, double end long threaded rod 4, nut 5, pressing plate 6, double end long threaded rod 4 is screwed into finish rolling roll change hydraulic cylinder bar 2 head, cylinder bar exntension tubs 3 are enclosed within the outside of cylinder bar 2 head and double end long threaded rod 4, pressing plate 6 is buckled in the end of cylinder bar exntension tubs 3 through double end long threaded rod 4, and nut 5 is screwed on double end long threaded rod 4 and pressing plate 6 and cylinder bar exntension tubs 3 is fixed with cylinder bar 2.
See Fig. 1-Fig. 7, adopt the device being used for changing at machine finish rolling roll change sealing piston of hydraulic cylinder to comprise the steps: the method that finish rolling roll change sealing piston of hydraulic cylinder is changed
1) pull down finish rolling roll change hydraulic cylinder cylinder head with inner hexagon spanner, moved to cylinder body side;
2) position detecting switch of cylinder bar is pulled down, and be placed on one side;
3) double end long threaded rod 4 is screwed into cylinder bar 2 head exposed;
4) cylinder bar exntension tubs 3 are enclosed within double end long threaded rod 4 and cylinder bar 2 head, pressing plate 6 are enclosed within double end long threaded rod 4, nut 5 is screwed on double end long threaded rod 4;
5) adjust cylinder bar exntension tubs 3, make it be integrated with 2 one-tenth, cylinder bar, now nut 5 is tightened, push down cylinder bar exntension tubs 3 by pressing plate 6, cylinder bar exntension tubs 3 are fixedly connected with cylinder bar 2;
With fine sandpaper, oilstone polishing cylinder bar exntension tubs 3 and cylinder bar 2 junction, note there is not the burr scraping hand, when preventing from retracting, damage the front sealing of finish rolling roll change hydraulic cylinder;
6) open the bonnet 8 of finish rolling roll change hydraulic cylinder, and clean out with the fluid of calico by outflow;
7) by cylinder bar exntension tubs 3, cylinder bar 2 is slowly ejected from front to back with jack, under chock is placed on piston, prevent piston from dropping suddenly and cylinder barrel damaged in collision surface;
8), after piston exposes completely, adjustment chock position and height, make piston seal 7 expose completely;
9) with the piston seal 7 that the tool changings such as screwdriver damage, around now attention keeps, operating environment is clean;
10) headed into by piston rod from back to front in cylinder chamber with jack, when noticing that observation heads into, whether sealing is intact;
11) clean the bonnet 8 of finish rolling roll change hydraulic cylinder with calico and recover its position;
12) the double end long threaded rod 4 of cylinder bar 2 head, nut 5, pressing plate 6 and cylinder bar exntension tubs 3 are pulled down;
13) cylinder bar position detecting switch is recovered;
14) cylinder head of finish rolling roll change hydraulic cylinder is recovered.
Through practice to 1700 Hot Line mm finishing mill unit, the utility model effectively achieve finish rolling roll change hydraulic cylinder sealing at machine quick-replaceable.Through tracking test, change the hydraulic cylinder works after sealing normal, sealing effectiveness is good.
