Description

A kind of cubic press concave bottom piston
Technical field
A kind of cubic press concave bottom piston is the utility model is related to, belongs to super-pressure synthesizing superhard material installation Technical field.
Background technology
Cubic press is mainly used in the superhard materials such as super-pressure diamond synthesis, cubic boron nitride, with pressure The development of machine equipment maximization, existing high pressure cylinder piston volume constantly increase, deadweight increase, cause piston to manufacture and assemble, pressure Machine adjustment is difficult, and piston hydraulic pressure seal support performance is poor, and the abrasion increase of seal, sealing effectiveness is deteriorated;Large-scale by six During the use of face toplap high-tension apparatus, in three piston packings among O-ring seal due to prolonged dry friction, Easy to wear, failure, influences sealing effectiveness;During the use of large-scale cubic press, the work between O-ring seal With working cylinder dry friction easily occurs for plug surface, causes working cylinder and piston failure.
Utility model content
The technical problems to be solved in the utility model is to overcome that prior art sealing is poor, accuracy of alignment is low, service life A kind of the defects of short, there is provided cubic press concave bottom piston.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme:
A kind of cubic press concave bottom piston, including piston, seal groove and connector, piston one end connection Have three O-ring seals, described in two of which between be equipped with oil storage tank in the middle part of O-ring seal, the piston rear end, which is provided with, is Spill mechanism, seal groove is cased with the O-ring seal, the piston is provided with anti-rotation component, and the piston other end is connected with The connector, is provided with keyway between the connector and the piston, the keyway side and set positioned at the internal piston There are some feather keys.
Preferably, some anti-rotation components are provided with the middle part of the piston, the anti-rotation component includes axially directed keyway and prevented Turn key.
Preferably, the antirotation keys are inserted in into the corresponding axially directed keyway.
Preferably, the oil storage tank is radial ringed groove.
The beneficial effect that the utility model is reached is:The concave bottom piston used in the utility model is not reducing piston sheet Under conditions of body intensity, rigidity, material is saved, the weight of piston is alleviated, the effective abrasion for reducing seal, is advantageous to set Standby installation and repairing and extra-high tension unit maximization;O-ring seal is designed with after twice oil storage tank, considerably increasing working cylinder Sealing property, reducing the fretting wear of piston and working cylinder inner surface, storage unit liquid separation presses oil twice oil storage tank in a pre-installation, Hydraulic oil has overflowed lubricant effect during piston movement, greatly reduces the abrasion of piston and cylinder body, ensures hydraulic system sealing; Built-in feather key and keyway, limit the rotation of piston, ensure that the centering of extra-high tension unit, while reduce pyrophillite Dust enters oil cylinder and causes the wear out failure phenomenon of sealing ring and piston;More convenient considerations, rational design, make it more than Possess the functions such as high-pressure tightness is good, accuracy of alignment is high, service life length.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and a part for constitution instruction, with this practicality New embodiment is used to explain the utility model together, does not form to limitation of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of concave bottom piston of the present utility model.
In figure:1st, piston;2nd, oil storage tank;3rd, spill mechanism;4th, seal groove;5th, anti-rotation component;6th, connector;7th, keyway; 8th, it is oriented to strong;9th, antirotation keys;10th, O-ring seal.
Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
As shown in figure 1, a kind of cubic press concave bottom piston, including piston 1, seal groove 4 and connector 6, it is living Fill in 1 one end and be connected with three O-ring seals 10, middle part is equipped with oil storage tank 2 between two neighboring O-ring seal 10, after piston 1 It is spill mechanism 3 that end, which is provided with, and O-ring seal is enclosed in seal groove 4, and piston 1 is provided with anti-rotation component 5, and the other end of piston 1 is connected with Connector 6, is provided with keyway 7 between connector 6 and piston 1, the side of keyway 7 and be provided with some feather keys 8 positioned at the inside of piston 1.
The middle part of piston 1 is provided with some anti-rotation components 5, and anti-rotation component 5 includes axially directed keyway and antirotation keys 9, prevents from living Plug rotates, and influences sealing effectiveness;Antirotation keys 9 are inserted in corresponding axially directed keyway, are easy to fix;Oil storage tank 2 is footpath To annular groove, it is easy to seal;
Specifically:As shown in figure 1, when the utility model uses:Spill mechanism 3 promotes hydraulic oil, and hydraulic oil is by sealing It can prevent hydraulic oil from revealing during groove 4, discharging liquid by extruding presses oil from oil storage tank 2 when O-ring seal 10 is slided, and reduces piston and work The fretting wear of cylinder inner surface, the middle part of piston 1 are provided with some anti-rotation components 5, and anti-rotation component 5 includes axially directed keyway and anti-rotation Key 9, prevents piston rotation, influences sealing effectiveness, and antirotation keys 9 are inserted in corresponding axially directed keyway, are easy to fix, storage Oil groove 2 is radial ringed groove, is easy to seal.
Finally it should be noted that:Preferred embodiment of the present utility model is the foregoing is only, is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic Carry out equivalent substitution.All any modification, equivalent substitution and improvements within the spirit and principles of the utility model, made etc., It should be included within the scope of protection of the utility model.
