Description
Technical field
The present invention relates to technical field of metallurgical equipment, in particular to a kind of device of 1800MPa fluid pressure.
Background technique
Metal hydrostatic extrusion is to force ingot blank to generate plasticity using the highly pressurised liquid being enclosed in extrusion cylinder around ingot blank and become
Shape and the Metal Forming method squeezed out from extrusion die die hole.Hydrostatic extrusion is a kind of by rubbing between metal ingot blank and tool
Resistance drop is wiped as low as the smallest ideal pressing method.The fluid pressure around hydrostatic extrusion ingot blank is up to 1200MPa at present.High pressure
The pressure of liquid can be forced the fluid into directly in extrusion cylinder with booster and be obtained, or compress the liquid in extrusion cylinder with pressure ram
Body obtains.For the hydrostatic extrusion of some difficult-to-deformation materials, the fluid pressure in extrusion cylinder needs to reach 1800MPa, for such as
This high super super-pressure needs safe reliable pressure method for building up and device.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a kind of 1800MPa fluid pressures
Device establishes the super superhigh pressure liquid pressure of 1800MPa by special sealing structure form and dedicated driving medium, in turn
Difficult-to-deformation material hydrostatic extrusion in extrusion cylinder is shaped, realizes the superplasticity processing of difficult-to-deformation material.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of device of 1800MPa fluid pressure, including extrusion cylinder 3,3 side of extrusion cylinder and master cylinder 8 are by squeezing
Compression bar 6 is connected, and master cylinder 8 is internally provided with the main plunger 7 that pressure ram 6 connects, and is provided on the extrusion cylinder 3 for injecting
At the injection liquid of driving medium 5, super super-pressure check valve 4, the setting of 3 other side of extrusion cylinder are provided at the injection liquid
There is mold 1, is provided with blank 2 between the mold 1 and check valve 4.
The driving medium 5 keeps preferable characteristics of liquids at 1800MPa, and driving medium 5 is hydrostatic medium.
The extrusion cylinder 3 is steel wire winding prestressing force extrusion cylinder.
O-ring seal 9 and triangular form copper sealing element 10, O-ring seal 9 and triangular form copper are provided at the mold 1
Sealing element 10 is horizontally disposed, and O-ring seal 9 is for adapting to inclined-plane at mold 1.
O-ring seal 9 and triangular form copper sealing element 10 are provided at the pressure ram 6, triangular form copper sealing element 10 is
Two, the acute angle of triangular form copper sealing element 10 is oppositely arranged, and O-ring seal 9 is located at the opening between triangular form copper sealing element 10
Place.
Beneficial effects of the present invention:
The present invention injects dedicated driving medium 5 in extrusion cylinder 3, injects and is equipped with super super-pressure check valve 4 at liquid,
Mold 1 while and when pressure ram 6 be respectively disposed with special sealing, super super-pressure can be sealed, master cylinder 8 is compressed by pressure ram to be squeezed
Liquid in pressure cylinder generates the fluid pressure for being up to 1800MPa, and difficult-to-deformation material is carried out by mold at such high pressures
Superplastic extrusion forming, becomes the hydrostatic extrusion product of high-quality.
The present invention is being squeezed using special driving medium, super super-pressure check valve, super superhigh pressure sealing and supercharging device

Support.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Dedicated driving medium 5 is injected in extrusion cylinder 3 as shown in Figure 1:, master cylinder 8 compresses extrusion cylinder 3 by pressure ram 6
Interior liquid generates the fluid pressure for being up to 1800MPa;Driving medium 5 (5) injection, inject liquid at be equipped with super super high-pressure single to
Valve 4;The driving medium 5, it is characterized in that keeping preferable characteristics of liquids at 1800MPa;In 1 side of mold and pressure ram 6
While being respectively disposed with special sealing O-ring seal 9 and triangular form copper sealing element 10.
The working principle of the invention:
The master cylinder 8 of extruder pushes main plunger 7 to advance under the operating pressure of working media, and main plunger 7 passes through pressure ram 6
Extruding force is acted on into hydrostatic medium 5, so that steel wire winding prestressing force extrusion cylinder 3 forms booster, has O-shaped sealing in front and back end
Circle 9 and 10 mating reaction of triangle copper sealing element, copper sealing element is deformed under the effect of superelevation fluid pressure, is played sealing and is made
With blank 2 of the end Jing Guo working process is held out against to fit closely on mold 1 in initial pressure by check valve 4 seals hydrostatic
Medium.Pressure of 3 tube filler of prestressing force extrusion cylinder of steel wire winding by steel wire winding layer, when can offset hydrostatic extruder extruding
Extrusion cylinder 3, to the power of the tangential direction of tube filler, is enabled steel wire winding prestressing force extrusion cylinder 3 to work super by hydrostatic medium
Under high pressure hydrostatic pressure medium.
