Abstract
The utility model discloses an end cap of a bending cylinder. The end cap adopts the structure that an O-shaped ring groove is designed on the excircle body of an integrated circular end cap body, a guiding ring groove, a tetrafluoro shaft sealing groove, a tetrafluoro shaft forward sealing groove, a tetrafluoro shaft reverse sealing groove and a dual-lip dust seal are sequentially designed from the small end of a through-hole in the end cap body. The end cap of the bending cylinder has the advantages of reasonable design and reliability in use, and improves the production efficiency.
Description
Technical field
The utility model relates to a kind of end cap, and particularly a kind of roller cylinder end cap is applicable to six roller reversing rolling mills.
Background technology
At present, the design of six roller reversing rolling mill roller cylinder end caps is single, can not satisfy need of work; Make the operating mode of six roller reversing rolling mill roller cylinders become abominable, after after a while, guiding reaches to prevent dust slight breakage can take place; When rolling belt steel thickness when being thinned to thick sudden change, working roll drives the roller cylinder piston rod and bounces back suddenly, makes roller cylinder rod chamber produce vacuum; Just there are some emulsions to be drawn onto in the roller cylinder rod chamber, and get back in the fuel tank with hydraulic oil.This process takes place repeatedly, and the emulsion in compensating cylinder and the roller cylinder Hydraulic Station is just more and more, removes very trouble, has brought inconvenience to production.
Summary of the invention
The utility model problem to be solved is, overcomes the deficiency of prior art, and a kind of roller cylinder end cap is provided.This end cap is not only reasonable in design, uses reliably, and has improved operating efficiency.
The technical scheme that the utility model adopts is: a kind of roller cylinder end cap is by being designed with O shape ring recess on the outer circle of the round end cap body that is made into one, and end cap body inner via hole is designed with guiding annular groove, tetrafluoro sealing groove, tetrafluoro axle forward seal groove, the reverse seal groove of tetrafluoro axle, lips dust ring in proper order and constitutes from microcephaly's end.During use, the utility model is connected into former position, can reliably use, realize the better seal effect.
The beneficial effect of the utility model is, and is rational in infrastructure, uses reliably, realizes the sealing between end cap and cylinder barrel, guiding and dustproof, and production cost has been practiced thrift in the sealing of piston rod, has improved production efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Accompanying drawing number is: 1, O shape ring recess, 2, the guiding annular groove, 3, tetrafluoro sealing groove, 4, tetrafluoro axle forward seal groove, 5, the reverse seal groove of tetrafluoro axle, 6, the dustproof ring recess of lips, 7, the end cap body.
The specific embodiment
With reference to Fig. 1; A kind of roller cylinder end cap is by being designed with O shape ring recess 1 on the round end cap body 7 outer circles that are made into one, and end cap body 7 inner via holes are designed with the reverse seal groove of guiding annular groove 2, tetrafluoro sealing groove 3, tetrafluoro axle forward seal groove 4, tetrafluoro axle 5, lips dust ring 6 in proper order and constitute from microcephaly's end.During use, the utility model is connected into former position, can reliably use, realize the better seal effect.
The employing of the utility model realizes the sealing between end cap and cylinder barrel, guiding and dustproof, the sealing of piston rod.
