Description
Technical field
The utility model is related to fluid high-pressure field of sealing technology, more particularly to a kind of high-pressure dynamic seal device.
Background technology
Hydroforming technology is one of equipment light-weighted mainstream technology of parts, and its principle is to utilize high-pressure fluid,
Be placed on the hollow pipe fitting in closed cavity, the swollen shape for expanding into die cavity, with efficiently, energy-conservation, complicated bend and variable cross-section advantage,
Rapidly become automobile and other industries integrated design, the new technology of lightweight manufacture.
During expansion that pipe fitting is swollen, pipe end is in high pressure sealing state；Seal and release after the completion of swollen expansion.High frequency is sealed with unsealing, and is
One of key technology of internal high pressure forming.Existing end sealing has used multi-step, sealing ring, interference to match somebody with somebody based on fixed pattern
The means such as conjunction, frequently impact in production, rub, wear and tear, and cause sealing device into the conventional easily-consumed products often changed, come into operation
Soon just there is different degrees of leakage, this fixed pattern Sealing Technology, later stage repair, waste are big, and working environment is also poor after leakage.
The content of the invention
The present invention replaces fixed pattern to seal with dynamic sealing, the stability of end sealing when solving internal high pressure forming, reliably
Property technical barrier, easy to use, safety, long lifespan.
In order to reach foregoing invention purpose, the utility model proposes following technical scheme：
High-pressure dynamic seal device, it includes rubber moulding group, puncture tip, reed, drift boss, punch holder, shear thickening liquid, led
To head, central tube, sealing ring, punch holder side is designed with drift boss, during the center of punch holder and drift boss is affixed
Heart Guan Bingyu medium channel insertions；It is provided with the inside of multigroup aperture, aperture and is set with the outside of covering reed, aperture on the tube wall of central tube
Rubber moulding group, the Position Design that rubber moulding group presses close to aperture has the puncture tip for stretching into aperture；Guide head is sleeved on central tube；Rubber moulding group
Drift boss is close in one end, and the other end is close to guide head；Between rubber moulding group and guide head, concentric sealing ring is embedded with.
Described punch holder is integrated machine-shaping with drift boss.
Described drift boss, rubber moulding group, the external diameter of concentric sealing ring and guide head, the internal diameter phase with pipe fitting to be formed
Together, and for negative common difference gap coordinate.
It is processed into groove shape in the outer of described guide head.
Shear thickening liquid and excellent sealing are inoculated with described rubber moulding group.
The utility model has the advantages that design is simple, and it is easy to use, sealed with dynamic sealing instead of fixed pattern, solve interior height
The stability of end sealing, reliability engineering problem, easy to use, safety, long lifespan during pressing formation.
Brief description of the drawings
Fig. 1 is the schematic cross-sectional view that the utility model high-pressure dynamic seal device is arranged on pipe fitting one end.
Embodiment
Referring to the drawings, high-pressure dynamic seal device is by rubber moulding group 2, puncture tip 3, reed 4, drift boss 5, punch holder 6, shearing
Thickening fluid 7, guide head 10, central tube 11, sealing ring 12 etc. are constituted.
Punch holder 6 is with drift boss 5 with being processed for disjunctor.The center of punch holder 6, affixed central tube 11 and and medium
The insertion of passage 1.Central tube 11 is provided with the inside of multigroup aperture, aperture suit rubber moulding group 2, rubber moulding group 2 on the outside of covering reed 4, aperture
Press close to the position of aperture, there is the puncture tip 3 for stretching into aperture.Guide head 10 is sleeved on central tube 11.It is close to punching in one end of rubber moulding group 2
Head boss 5, the other end is close to guide head 10.Between rubber moulding group 2 and guide head 10, concentric sealing ring 12 is embedded with.Drift boss
5th, the external diameter of rubber moulding group 2, concentric sealing ring 12 and guide head 10, it is identical with the internal diameter of pipe fitting 9 to be formed, and between negative common difference
Gap coordinates.Groove shape is processed into the outer of guide head 10, play the guiding role.Fluid is entered or extracted out by medium channel 1.Punch holder
6 can be promoted by external force.
Implementation process is as follows：
Pipe fitting 9 is put into die cavity, upper mould 8 and the lower matched moulds of mould 13 and completes locked mode.External force is promoted before the device entirety of punch holder 6
Move.Guide head 10 enters pipe end until pipe fitting end face props up drift boss 5.
Gas in low-pressure fluid discharge pipe, the reverse compression under low-pressure fluid effect of guide head 10 are pumped into from medium channel 1
Concentric sealing ring 12 and adjacent rubber moulding group 2, produce bullet become sealing ring 12 and rubber moulding group 2 tightly touch the inwall of pipe fitting 9 and
The outer wall of central tube 11.Continue quickly to be pumped into high-pressure fluid to medium channel 1, reed 4 occurs elasticity and collapsed under high pressure, hit thorn
Point 3 is pierced into the shear thickening liquid 7 in rubber moulding group 2, and the shearing force that puncture tip 3 is produced in shear thickening liquid 7 makes shear thickening liquid 7
Instantaneously become hard solid-state from liquid.Now, rubber moulding group 2, sealing ring 12 have each served as good rigid and soft in pipe end
The sealing function of property.
Pipe fitting forming terminates, and pressure is decorporated.Reed 4 resets, and shear thickening liquid 7 loses shearing effect and becomes liquid again, close
Seal ring 12 restores to the original state, and returning to normal pressure gap from high pressure interference fit coordinates, and device integrally easily exits pipe end, into lower all one's life
The production cycle.
By the elastic deformation of sealing ring 12, the phase change transition of shear thickening liquid 7, complete gap and be coupled to interference fit
Invertible operation, abrasion and leakage without conventional seal techniques, it is not required that frequently repair, fully meet internal high pressure forming
The technological requirement of dynamic sealing.
