Description

A kind of cubic hydraulic press hinge beam cylinder base oil circuit mechanism
Technical field
This utility model belongs to cubic hydraulic press equipment manufacturing technology field, relates generally to a kind of cubic hydraulic press hinge Chain beam cylinder base oil circuit mechanism.
Background technology
Bottom hinge beam, oil circuit mechanism is building block important in cubic hydraulic press, and the operation synthesis action of press is By oil circuit mechanism fuel feeding bottom hinge beam, hydraulic oil promotes piston to move extruding pyrophyllite block and completes work, oil circuit mechanism On rear stifled and three-way valve block, cone blocking be then important oil circuit parts;Operating pressure >=the 80Mpa of hydraulic press, due to building ring The hyperpressure in border, is sealed with strict demand to hydraulic tube piece and hydraulic valve piece, simultaneously as material stifled after rear stressed member Performance and version also have strict restriction.Rear stifled, three-way valve block in cubic hydraulic press oil circuit mechanism in currently available technology With the structure of cone blocking, the raising meeting operating pressure is had the biggest restriction, is primarily present following problem:
1, rear stifled design with hinge beam back plane and two kinds of forms of working cylinder back plane are installed, after being installed on hinge beam Plane form because of hinge beam be cast member, there is the casting flaws such as loose, the pore of casting, there is leakage of oil under high pressure conditions, ooze Oil phenomenon, causes hinge beam scrappage higher, adds that the hinge beam product manufacturing cycle is long, cause cost to increase;It is installed on work Cylinder back plane form, because working cylinder is stress workpiece, bottom is carried out multiple location machining, under supertension state, with Stress-number of cycles to increase and the change of working environment, working cylinder shortens rapidly actual life, causes equipment fault.
2. piston pressure promote under be easy to move to extreme position, in prior art, bottom working cylinder be one whole Plane, piston is too small with working cylinder bottom gap, when producing adhesive, causes working cylinder function of increasing pressure to be lost, and hydraulic coupling can not push away Dynamic piston moves.
3, three-way valve block internal seal structure of the prior art uses oil sealing sealing or rubber sealing, uses above-mentioned sealing Time, black box connects tension and causes oil sealing or cushion rubber deformation, ruptures, and when being in environment under high pressure, powerful pressure has punching Hitting property and mobility, can make the broken thing of oil sealing or cushion rubber enter hydraulic circuit, cause the faults such as oil circuit blocking, card valve.
Summary of the invention
For the problem in the presence of prior art, this utility model devises a kind of cubic hydraulic press hinge beam cylinder body Bottom oil circuit mechanism, mentality of designing of the present utility model is: 1, change the rear bridging structure in oil circuit mechanism, stifled as independent after making Oil circuit mechanism directly fuel feeding in working cylinder, simultaneously at rear stifled circumferencial direction design twice step to improve at superelevation pressure ring The hinge beam of safety stifled after under border and solution casting is easily generated Lou, the problem of permeability;2, by liquid in prior art Force feed pipeline seals and is changed into the double tapered face seal of wedge angle of metal tubes by the mode of oil sealing sealing or seal with elastometic washer, improves hydraulic pressure Oil pipe line is pressure, compressive property, reduces the equipment fault produced because of oil circuit, valve member blocking;3, the length of cone blocking, same phase are changed Length and size with cone blocking mating holes on stifled and three-way valve block after the increasing answered, and reduce fit clearance, to solve to install The easy deflection of cone blocking in journey, the problem installing operating difficulties.
For achieving the above object, the concrete technical scheme that this utility model is taked is: a kind of cubic hydraulic press hinge Chain beam cylinder base oil circuit mechanism is mainly made up of rear stifled, cone blocking, three-way valve block, connecting bolt;Wherein;At rear stifled circumferential body On be respectively equipped with twice resistance to compression step;After get lodged in the rigging position on hinge beam and working cylinder to first resistance to compression step;Rear stifled The face contacted with working cylinder is provided with spill and holds oil groove;After being provided with at the rear stifled rear end hydraulic oil pipeline input mouth of pipe, stifled guiding is fixed Hole, position, is designed with two wedge angles of step in rear stifled guide-localization hole;For rear stifled close with hydraulic oil pipeline on threeway valve member The cone blocking of envelope uses metal tube to make, and the two ends of cone blocking are designed to double wedge angle type conical surface, and the circumference of cone blocking is processed into spigot surface; It is provided with threeway guide-localization hole, threeway guide-localization hole with rear stifled hydraulic oil pipeline input mouth of pipe opposite position on threeway valve member Inside it is designed with two wedge angles of step that the double wedge angle type conical surfaces with cone blocking mate;The spigot surface of cone blocking is at the spinning of connecting bolt Under power effect, threeway guide-localization hole running fix on rear stifled guide-localization hole and threeway valve member, its cone blocking two ends double The wedge angle type conical surface respectively with two step wedge angles in rear stifled guide-localization hole and two steps in threeway guide-localization hole Closely fit after formula wedge angle centering centering, it is achieved oil circuit seals.
A kind of cubic hydraulic press of the present utility model hinge beam cylinder base oil circuit mechanism provides the benefit that: by right The optimization design of oil circuit mechanism, stifled as independent oil path mechanism directly fuel feeding in working cylinder after making;At rear stifled circumferencial direction The twice step of upper design, safety stifled after improve under ultra-high voltage environment, solve hinge beam be easily generated Lou, the asking of permeability Topic;By increasing the design holding oil groove in rear stifled working cylinder direction, solve piston movement to working cylinder after extreme position with after The stifled adhesive problem produced;Use the cone blocking of double wedge angle type conical surfaces in metal tubes to seal, instead of oil sealing sealing and rubber Circle seals, and improves that hydraulic oil pipeline is pressure and crushing resistance, decreases the equipment fault produced because of oil circuit, valve member blocking.This reality Novel by new design, simple in construction, effectively raise cubic hydraulic press device fabrication quality, greatly improve Production efficiency.
