Abstract
The utility model relates to a rubber diaphragm for a hydraulic breaking hammer accumulator, which aims to solve the technical problems existing in the prior art of poor sealing effect and short service life and the like. The utility model comprises a sealing portion, a buffer portion and an impact portion, which is characterized in that a round of projections for increasing the sealing property are arranged on the sealing portion, the bottom surface of the impact portion is a concave arc surface, and the material of the rubber diaphragm is hydrogenated nitrile rubber. Owing to adopting the structure in the utility model, the projections of the sealing portion are arranged to greatly increase the sealing property of the rubber diaphragm. Additionally, as the hydrogenated nitrile rubber is highly saturated rubber, and the rubber diaphragm can not change high elasticity and sealing property in concentrated oil dense solvent for a long term. Therefore the utility model does not easy to be aging under high temperature condition for a long term, and can keep the high elasticity and high sealing property of rubber, and greatly increases service life.
Description
Technical field
The utility model relates to a kind of hydraulic breaking hammer accumulator diaphragm of rubber, specifically to having a kind of improvement of diaphragm of rubber now.
Background technology
At present, in the construction machinery of hydraulic breaking hammer one class, be to convert hydraulic pressure kinetic energy to impulse machine by accumulator can carry out work, should seal up the liquid that is generally nitrogen as the diaphragm of rubber in the accumulator of critical component strict leakproof, bear up to the operating temperature more than 100 ℃ again and subdue repeatedly, under HTHP, work again and again.What prior art adopted is mechanical diaphragm, composite diaphragm, polyurethane barrier film and General Purpose Rubber barrier film.Shortcomings such as above-mentioned diaphragm of rubber exists all that sealing effectiveness is poor, non-refractory, not anti-dense oil, not anti-dense solvent and application life are short.
Summary of the invention
The purpose of this utility model is in order to solve technical problems such as the sealing effectiveness that prior art exists is poor, application life is short, and a kind of diaphragm of rubber that can keep high resiliency, high leakproofness for a long time that provides.
In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of hydraulic breaking hammer accumulator diaphragm of rubber, comprise sealing, buffer part and shock resistance portion, it is characterized in that: described sealing is provided with the projection of a circle enhanced leaktightness, and the bottom surface of shock resistance portion is the arcwall face of indent, and the material of described diaphragm of rubber is a hydrogenated nitrile-butadiene rubber.
In further detailed structure of the present utility model, also has following technical characterictic: be embedded with the sheet metal that can improve its rigidity in the described shock resistance portion.
In further detailed structure of the present utility model, also have following technical characterictic: the thickness of described shock resistance portion is by the attenuation gradually of centre to both sides.
In further detailed structure of the present utility model, also have following technical characterictic: described projection is a hemispherical.
In further detailed structure of the present utility model, also have following technical characterictic: the radian of described shock resistance portion bottom surface is 2.5 °-60 °.
Compared with prior art, the utlity model has following advantage and good effect:
Because the utility model has adopted said structure, the setting of sealing projection has improved the sealing of diaphragm of rubber greatly, and in addition, because hydrogenated nitrile-butadiene rubber is high saturated rubber, it does not change high resiliency and sealing in the dense oil dense solvent midium or long term.Therefore the utility model is worked under hot environment for a long time and is difficult for wearing out, and keeps the high resiliency and the high leakproofness of rubber, has improved its its application life greatly.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 1-Fig. 5, the utility model diaphragm of rubber is bowl-shape, and it comprises a circle sealing 10 of upper end, a circle buffer part 20 of side, and the shock resistance portion 30 of bottom.The thickness of shock resistance portion 30 can be by the attenuation gradually of centre to both sides.Sealing 10 is provided with the hemispherical projections 11 of a circle enhanced leaktightness, and the bottom surface of shock resistance portion 30 is the arcwall face of indent, and its radian is 2.5 °-60 °, and the difference of radian size is applicable to the hydraulic breaking hammer accumulator of various different models.Can also vulcanize sheet metal 31 in the combination in the bottom surface of shock resistance portion 30 as required, to improve the rigidity of diaphragm of rubber.The material of this diaphragm of rubber is a hydrogenated nitrile-butadiene rubber.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
