Description
Technical field
The utility model belongs to technical field of hydraulic equipment, relates to a kind of roll-bending cylinder of Krause mill roller.
Background technique
Roll-bending cylinder is one of important composition parts of mill roll bending device, for providing the bending roller force of continuous and effective to rolling mill roll, such that the life cycle of roll-bending cylinder is shorter, the piston rod of roll-bending cylinder and guide sleeve inner wall abrasion more serious.In addition, existing milling train in process of production, there is the comparatively large and frequent oil impregnate in roll-bending cylinder cylinder cap place of the forward and backward amplitude of fluctuation of roll-bending cylinder piston, if process not in time, meeting leakage of oil always, strengthens milling train servo-system fluid and consumes, and roller roughing leakage of oil, just inaccurate during bending system calculating bending roller force, influence zone steel rider type, causes product convexity and wedge shape not controlled.Therefore, the direction becoming these those skilled in the art and make great efforts how is solved the problems of the technologies described above.
Model utility content
For above shortcomings in prior art, the utility model provides a kind of roll-bending cylinder, this roll-bending cylinder not only reasonable in design, safe and reliable, and improves working efficiency, extends working life.
The utility model is achieved through the following technical solutions:
A kind of roll-bending cylinder that the utility model provides, comprise gray iron, cylinder bar and guide sleeve, one end of described cylinder body is closed and is formed cylinder bottom, the other end is the external part of cylinder bar and is connected with cylinder cap, described guide sleeve is arranged in cylinder body, and to be sheathed on cylinder bar and to be connected with cylinder cap, described guide sleeve is provided with the extension part stretching out direction to cylinder bar, be sequentially set with Sealing and dust ring from left to right in described extension part, described Sealing and dust ring are successively set in the corresponding groove of guide sleeve extension part inner via hole.
Further, the axial length of described guide sleeve extension part is determined according to the extending amount of cylinder bar work.
Further, described Sealing is set at least 2.
Further, the material of described guide sleeve is alloyed copper.
Further, described cylinder bar is solid cylinder bar.
Further, described Sealing is made up of polymer rubber material or metal-rubber material.
Further, described dust ring is lips dust ring.
Advantageous Effects of the present utility model is: the utility model is rational in infrastructure, safe and reliable, realizes the sealing between guide sleeve and cylinder bar, guiding and dust-proof, extends working life.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by specification below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is the utility model structural representation;
Fig. 2 is guide sleeve sectional view of the present utility model;
Reference character: 1-cylinder body, 2-cylinder cap, 3-cylinder bar, 4-guide sleeve, 5-Sealing, 6-dust ring.
Embodiment
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail; Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
As shown in the figure, a kind of roll-bending cylinder that the utility model provides, comprise cylinder body 1, cylinder cap 2, cylinder bar 3 and guide sleeve 4, one end of described cylinder body 1 is closed and is formed cylinder bottom, the other end is the external part of cylinder bar 3 and is connected with cylinder cap 2, described guide sleeve 4 is arranged in cylinder body 1, and to be sheathed on cylinder bar 3 and to be connected with cylinder cap 2, described guide sleeve 4 is provided with the extension part stretching out direction to cylinder bar 3, described extension part from left to right order in be provided with Sealing 5 and dust ring 6, described Sealing 5 and dust ring 6 are successively set in the corresponding groove of guide sleeve 4 extension part inner via hole, the extending amount that the axial length of described guide sleeve 4 extension part works according to cylinder bar 3 is determined, described Sealing 5 is set at least two.
Concrete, the utility model in use, because guide sleeve 4 is provided with outside extension part, therefore do not reducing under the movement travel of cylinder bar 3 in cylinder body 1, add the length of guide sleeve 4, and then the swing reduced in cylinder bar 3 movement process in the radial direction thereof, enhance the working life of Sealing 5 and dust ring 6; Meanwhile, be also provided with at least two Sealings 5, roll-bending cylinder is not revealed, ensure that bending system calculates bending roller force accurate, ensure roll profile, coil of strip convexity and wedge shape are effectively controlled, and decrease fluid consumption, reduce cost, enhance the rolling power of milling train.
In the present embodiment, the material of described guide sleeve 4 is alloyed copper, is conducive to like this reducing the friction between cylinder bar 3 and guide sleeve 4, increases its life cycle.
In the present embodiment, described cylinder bar 3 is solid cylinder bar, ensure that the swing that can to effectively reduce in rolling process in the running of roll-bending cylinder cylinder bar 3 in the radial direction thereof, thus both reduced the damage of roll-bending cylinder Sealing 5 and dust ring 6, in turn ensure that the quality of rolled plate.
In the present embodiment, described Sealing 5 is made up of polymer rubber material, adopt polymer rubber Sealing, not only there is the elasticity of rubber, larger damping and frictional force can also be obtained to suppress cylinder bar 3 swing in the radial direction thereof, effectively can improve the impacting force of Sealing body to cylinder bar 3, thus reach the object strengthening airtight quality.Certainly, in various embodiments, the seal that metal-rubber material is made can also be adopted, like this special with extreme environment (high and low temperature, high pressure) there is the inherent characteristic of selected metal, have again and be similar to the same elasticity of rubber, under space environment, do not fear high and low temperature, and may characteristic be waited without aging.
In the present embodiment, described dust ring 6 is lips dust ring, can not only effectively prevent entering of dust dirt sand grains impurity, also prevent scratch greatly, and protection cylinder bar 3, extends the working life of roll-bending cylinder.Further, lips dust ring is continuous annular, can be easy to be loaded in the groove of guide sleeve 4.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of the technical program, it all should be encompassed in the middle of right of the present utility model.
