Abstract
The invention discloses a high-reliability cylinder cover comprising a cylinder cover body and a seal ring. The seal ring is disposed below the cylinder cover body. The cylinder cover body is made by melting, by weight, 75 to 84% of forged steel and 16 to 25% of nickel at high temperature; the seal ring is made by melting, by weight, 64 to 72% of polyvinyl chloride plastic and 28 to 36% of ethylene propylene rubber. The high-reliability cylinder cover made in the above way has the advantages that mechanical properties of the cylinder cover body such as physical strength are greatly improved, the cylinder cover body never wears in long-term usage, the seal ring is excellent in corrosion resistance, wear resistance and sealing performance, and the high-reliability cylinder cover is effective.
Description
Technical field
The present invention relates to Hydraulic Field, particularly a kind of high reliability oil cylinder cover.
Background technique
Oil cylinder refers generally to oil hydraulic cylinder, and hydraulic energy is changed into mechanical energy, does the hydraulic actuator of straight reciprocating motion (or oscillating motion) by oil hydraulic cylinder.Its structure is simple, reliable operation.When realizing to-and-fro motion with it, can speed reducer be removed from, and there is no drive gap, stable movement, therefore be used widely in the hydraulic system of various machinery.Oil cylinder cover is as a power element, a stronger mechanical strength is needed to support in use, otherwise easily occur damaging, change frequently and improve cost, and in order to ensure a good sealing, then needing to add seal ring on oil cylinder cover, the quality of seal ring have impact on the using effect of oil cylinder equally, therefore, a good seal ring is prerequisite equally.
Summary of the invention
The technical problem that the present invention mainly solves is to provide each side physical properties such as a kind of mechanical strength of oil cylinder cover body and greatly improves, enable oil cylinder cover body stand long use not wear and tear, the corrosion resistance of seal ring, wear resistance, sealability are excellent, and using effect is good.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of high reliability oil cylinder cover, comprise: oil cylinder cover body and seal ring, described seal ring is arranged on the below of described oil cylinder cover body, described oil cylinder cover body is formed by forged steel and nickel high-temperature fusion, according to weight percentage proportioning: the content of described forged steel accounts for 75-84%, the content of described nickel accounts for 16-25%, described seal ring is formed by igelite and ethylene propylene rubber melting, according to weight percentage proportioning: the content of described igelite accounts for 64-72%, the content of described ethylene propylene rubber accounts for 28-36%.
In a preferred embodiment of the present invention, in described oil cylinder cover body, the concrete proportioning of composition is: the content of described forged steel accounts for 76%, and the content of described nickel accounts for 24%.
In a preferred embodiment of the present invention, in described seal ring, the concrete proportioning of composition is: the content of described igelite accounts for 65%, and the content of described ethylene propylene rubber accounts for 35%.
In a preferred embodiment of the present invention, the thickness of described seal ring is 1-3mm.
The invention has the beneficial effects as follows: the present invention can make each side physical properties such as the mechanical strength of oil cylinder cover body greatly improve, and enable oil cylinder cover body stand long use not wear and tear, the corrosion resistance of seal ring, wear resistance, sealability are excellent, and using effect is good.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Embodiment 1:
A kind of high reliability oil cylinder cover, comprise: oil cylinder cover body and seal ring, described seal ring is arranged on the below of described oil cylinder cover body, described oil cylinder cover body is formed by forged steel and nickel high-temperature fusion, according to weight percentage proportioning: the content of described forged steel accounts for 76%, the content of described nickel accounts for 24%, and described seal ring is formed by igelite and ethylene propylene rubber melting, according to weight percentage proportioning: the content of described igelite accounts for 65%, the content of described ethylene propylene rubber accounts for 35%.
