Abstract

The utility model provides a bush type working roll balance cylinder block which comprises a cylinder block body. The bush type working roll balance cylinder block is characterized in that the two ends of the cylinder block body are provided with two cylinder barrels, a bush is arranged in each cylinder barrel and is located and compressed into the corresponding cylinder barrel through an end cover, static seals are arranged between the end covers and the cylinder block body, a piston rod is arranged in each bush, a movable seal and a dustproof ring are arranged between each piston rod and the corresponding end cover, and a static seal is arranged between each bush and the corresponding cylinder barrel. After the bush type working roll balance cylinder block is used for a long time, once the abrasion of the inner diameter of each bush exceeds standards, only the bush needs replacing, and the cylinder block does not need replacing, so that the time for maintenance is greatly reduced, the labor intensity of on-site workers is reduced, and working efficiency is improved.

Description

Bush type machine working roller balance cylinder piece
technical field:
The utility model relates to a kind of bush type machine working roller balance cylinder piece, belongs to technical field of hydraulic oil cylinder.
background technology:
The function of hydraulic cylinder is to convert hydraulic energy to mechanical energy.Hydraulic cylinder input be flow and the pressure of fluid, output be speed and power.Hydraulic cylinder is made up of cylinder barrel and cylinder cap, piston and piston rod, sealing device etc. substantially.Due in mill stand about the part (between housing screw and nut, bearing and roll neck) cooperatively interacting exists fit clearance, therefore the in the situation that of milling train zero load, the Gravitative Loads of each part, will cause between the screw thread of housing screw and nut, between working roll and roll surface and all have certain gap between roll neck and bearing.And this gap will inevitably produce strong impact phenomenon (mill speed is higher more serious) in the operation of rolling, consequently make the milling train correlated parts life-span reduce, roll gap changes, and rolled piece is nipped unfavorable; Also can cause between working roll and backing roll and occur skidding simultaneously, thereby cause that rolled piece produces the phenomenon on wave and scratch rolled piece surface, declines the quality of sheet material greatly.In order to eliminate in rolling Biting Course, because having the caused impact phenomenon in gap between relevant part in milling train, improve bite condition, prevent from producing skidding etc. between working roll and backing roll simultaneously, be almost all provided with bascule at all milling trains.Modal is exactly machine working roller balance cylinder, and the equilibrant force of its generation compresses upper working rolls and lower working rolls respectively with upper lower backing roll, and when avoiding rolling, top working roll contacts unstable vibrations with upper backup roll, guarantees rolling stability.Machine working roller balance cylinder has eight, and upper working rolls and lower working rolls compensating cylinder respectively has four, is oppositely arranged in pairs on four cylinder pieces.Oil cylinder in use for some time cylinder barrel will wear and tear, once wearing and tearing exceed standard and must change the reparation of rolling off the production line, because cylinder piece is heavier huge, liner plate, the plate of locking a door are also installed on cylinder piece, lock a door an edition oil cylinder, hydraulic oil pipe etc., and because construction space in frame is narrow and small, changing a cylinder block at least needs the time of 15 hours.Chinese patent CN200720012660.7 discloses a kind of " a kind of balance hydraulic cylinder of support works roller of rolling mill ", the self-defence piece of its design can not produce the stress of inclination, cause rigid connection the between piston rod and working roll bearing block, piston rod is no longer together all around swung with working roll bearing block in the time of steel rolling, piston rod stability under loading, extends service life of balance hydraulic cylinder greatly.Avoid working roll bearing block to form pit.The swing that the sphere of piece lower end of simultaneously defending oneself can compensation work roll bearing seat produces in the time of rolling, improve balance hydraulic cylinder stress.But it also there will be long problem of replacing time while changing cylinder block.
utility model content:
The purpose of this utility model is to provide a kind of bush type machine working roller balance cylinder piece for the problem of above-mentioned existence, and wearing and tearing are changed convenient, saves the maintenance replacing time, reduces the labour intensity of field worker, has improved operating efficiency.And can eliminate circular runout that roll seam the causes injury to piston rod, greatly extend the service life of piston rod.
Above-mentioned object realizes by following technical scheme:
Bush type machine working roller balance cylinder piece, comprise cylinder block body, the two ends of described cylinder block body are provided with two cylinder barrels, each described cylinder barrel the inside is provided with lining, described lining in described cylinder barrel the inside, is provided with static seal, described lining the inside installation piston rod between described end cap and described cylinder block body by end cap positioning compression, between described piston rod and described end cap, movable sealing and dust ring are installed, between described lining and described cylinder barrel, static seal are installed.
Described bush type machine working roller balance cylinder piece, described piston rod is hollow tubular, and described piston rod the inside is equipped with base, top and elastomer successively, and described base and the contact site of top are designed to hemisphere face.
Beneficial effect:
The utility model, after long-time use, once the wearing and tearing of the internal diameter of lining exceed standard as long as lining is changed, without changing cylinder piece, has been saved the maintenance replacing time greatly, reduces the labour intensity of field worker, has improved operating efficiency.Piston rod of the present utility model is hollow tubular, described piston rod the inside is equipped with base, top and elastomer successively, described base and the contact site of top are designed to hemisphere face, can eliminate circular runout that roll seam the causes injury to piston rod, greatly extend the service life of piston rod.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
In figure: the 4--base of 1-elastomer 2--end cap 3--top
5--piston rod 6--lining 7--cylinder block body 8--cylinder barrel
the specific embodiment:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1: bush type machine working roller balance cylinder piece of the present utility model, comprise cylinder block body 7, the two ends of described cylinder block body are provided with two cylinder barrels 8, each described cylinder barrel the inside is provided with lining 6, described lining passes through end cap 2 positioning compressions in described cylinder barrel the inside, between described end cap and described cylinder block body, static seal is installed, piston rod 5 is installed in described lining the inside, between described piston rod and described end cap, movable sealing and dust ring are installed, between described lining and described cylinder barrel, static seal are installed.Design must design when lining and prevent the strain of lining under hydraulic oil effect, thus the wall thickness of lining determined by design pressure and the lagging material of oil cylinder, lagging material is generally selected wear-resisting alloy steel.
Embodiment 2:
Bush type machine working roller balance cylinder piece described in embodiment 1, described piston rod is hollow tubular, and described piston rod the inside is equipped with base 4, top 3 and elastomer 1 successively, and described base and the contact site of top are designed to hemisphere face.
