Description
Technical field
The invention belongs to the technical field of the quiet high-pressure installation of generation that uses in and the high-pressure science research synthetic at superhard material.
Background technology
High temperature and high pressure environment is to carry out artificial necessary condition of synthesizing superhard materials such as making diamond, cubic boron nitride (cBN) and the research of relevant high-pressure science.The large quiet high-pressure installation of cavity is the capital equipment that produces high temperature and high pressure environment.The correlation technique of this device is grown up last century by people such as Bridgman, and constantly is improved.Mainly contain at present top, two sides and polyhedron high-pressure installation.Wherein the maximum pressure that produces of Belt-type press is about 12Gpa; And the polyhedron press device comprises hexahedron pressure chamber device and the octahedra chamber device of pressing, and the maximum pressure of generation has larger difference.Different according to design principle, cubic hinge press can be divided into: the DIA cubic hinge press, and based on the cubic hinge press of belt type press framework, and the hinge type cubic hinge press.The DIA cubic hinge press and based on the cubic hinge press of top, two sides framework because complex structure, processing difficulties, with high costs, be mainly used in the HTHP at synchrotron radiation station at bit test, be rarely used in suitability for industrialized production synthesizing superhard material.The hinge type cubic pressure machine of China's independent research has hexahedron and presses the chamber, compact conformation, and processing and installation are relatively simple, and cost is also relatively cheap.This equipment has been widely used in China's China superhard material Industry at present, is the main production equipments that China becomes the superhard material great industry nation.In the prior art, press anvil (being top hammer) corresponding to the tungsten carbide (WC) of certain diameter, the designer is used for obtaining the synthetic cavity maximization in order to obtain enough large anvil face.Therefore, prior art can obtain maximum pressure and is about 7Gpa in equipment.This technology can not satisfy the needs of high-pressure science technical development.
In DIA cubic hinge press and the cubic hinge press based on top, two sides framework, adopt carbide alloy (WC) pressure anvil or diamond, cubic boron nitride sintered body as pressing anvil, the cavity maximum pressure can reach 15Gpa.And the secondary six take the belt type press framework as the basis-octahedron is pressed the quiet high-pressure installation in chamber.Adopt tungsten carbide (WC) as the octahedra compress cell material in the second level, chamber pressure can be up to 30Gpa.Because chamber pressure is higher, this technique device has been widely used in the world high-caliber quiet High-Voltage Experimentation chamber.Compare with hinge type cubic pressure machine technology, the DIA cubic press, based on the cubic pressure machine of top, two sides framework and the large quiet high-pressure installation of cavity of secondary six-octahedron, axial compressive force need to be converted to the pressure of six direction, complex structure, the shortcomings such as the pressure conversion efficiency is low, and price is very expensive, and maintenance cost is high, from the large quiet high-pressure installation of cavity of foreign procurement one cover secondary six-octahedron, amounting to needs RMB about 5,000,000.
In recent years, the quiet high-pressure installation of hexakisooctahedron (seeing Chinese patent ZL200710048839.2) based on hinge beam type cubic hinge press that professor He Duanwei grows up, chamber pressure can be up to 20Gpa.In this technology, they have adopted the two-stage supercharging unit material that is similar to based in slide block type six-octahedron in the framework of top, two sides equally, namely adopt two-stage supercharging to form the octahedra chamber of pressing and produce quiet high pressure.
Summary of the invention
The present invention wants the technical solution problem, for having now in the high pressure technique for generation of the deficiency that exists in the large quiet high-pressure installation of cavity, aim to provide a kind of simple in structure, pressure conversion efficient height, cost is low, high-efficiency low energy consumption, maintenance work are simple, for generation of the new device of large-cavity ultrahigh hydrostatic pressure.
Device for generation of quiet high pressure of the present invention, on the basis of cubic hinge press, by designing novel pressure anvil, reduce the anvil face size, optimize the physical dimension of pressing anvil, the corresponding material that is used for this pressure anvil of assembling of design forms the cubic apparatus large-cavity ultrahigh hydrostatic pressure device based on the cubic pressure mechanism rack.This device comprises synchronously driven six the pressure anvils of cubic hinge press, the steel loop that is used for six pressures of assembling anvils and the multistage cushion block that is used for transmission of pressure.Six materials of pressing anvils can be selected a kind of of tungsten carbide, diamond, cubic boron nitride polycrystalline sintered body, perhaps select a kind of in the composite of sintering preparation between them; Assembling presses the steel loop of anvil to adopt hard alloy steel; Multistage cushion block material comprises steel alloy and carbide alloy WC.The said large cavity of the present invention is mm
3The cavity of magnitude.
The concrete technical scheme of the present invention is:
A kind of device that produces large-cavity ultrahigh hydrostatic pressure, be based on the large-cavity ultrahigh hydrostatic pressure device of cubic pressure mechanism rack, structure comprises synchronously driven six the pressure anvils 1 of cubic hinge press, the steel loop that is used for six pressures of assembling anvils and the cushion block that is used for transmission of pressure, it is characterized in that, described pressure anvil 1, the length of side of its anvil face 2 are 1～6 millimeter; Described cushion block is the secondary cushion block that steel alloy cushion block 6 and tungsten carbide cushion block 5 consist of, and wherein tungsten carbide cushion block 5 is placed on and presses between anvil 1 and the steel alloy cushion block 6.That is, anvil 1 is pressed in 5 contacts of carbide alloy tungsten carbide cushion block.
