Technical field
The present invention relates to clamping device, be specifically related to the clamping device that is used as electrode and contains cooling system under a kind of superhigh temperature.
Background technology
Superhigh temperature ceramics refers to that fusing point, higher than the class compound substance of 3000 degrees Celsius, mainly comprises boride, carbonide and nitride that hafnium, zirconium, tantalum etc. form.Such stupalith has good conduction, electric heating, and therefore the chemistry of high temperatures, mechanical property, and the stronger character such as inoxidizability are widely used in high-speed aircraft, reenter aerospace engineering etc.High-speed aircraft to reenter Mach number generally all very large, due to its in reentering process its front end and surface and air fiercely rub, thereby produce a large amount of Aerodynamic Heatings, make its surface temperature moment rise to several thousand degrees Celsius, thermal conductivity, fracture toughness, physical strength and the inoxidizability of therefore studying conductivity ceramics under superhigh temperature have important national defence meaning.The dynamic heat simulating tester Gleeble of series of U.S. DSI company research and development utilizes the electrical heating can transient heating test specimen, but heating-up temperature bans the sale of while surpassing 1800 degrees Celsius to China, so the fixture of the Gleeble selling to China can only be worked at the most under 1800 degrees Celsius.Industrial heating furnace can be heated to 2200 degrees Celsius, but has reached the heatable upper limit, and its heating cycle is long, generally wants two to three days, and test specimen, fixture and stove are heated together, and efficiency is very low, to fixture, requires high.Therefore autonomous research electric heating equipment is imperative, and fixture is pith in equipment.A kind of drawing by high temperature pipe material clamp is disclosed in CN102288482A, this high-temperature clamp comprises: an outer sleeve, a push rod, an inner sleeve, one group of clamping watt identical with gathering sill quantity, is mainly used in the tubular product sample that high temperature tensile properties detects .GB/T4338-2006.Though this device can at high temperature be worked, be only the fixture of a set of stretching tubing, do not possess electrode function, there is no cooling system.
Summary of the invention
Object of the present invention is exactly in order to overcome the deficiency of above-mentioned background technology, and the fixture that is used as electrode and contains cooling system under a kind of superhigh temperature is provided.
The fixture that is used as electrode and contains cooling system under superhigh temperature of the present invention, its material is tungsten-copper alloy, and fixture is comprised of four grip blocks, and each grip block has blasthole, apopore, fixed orifice, power supply access groove, every two grip blocks are one group, and two groups form a grasping system; Cooling system shape on grip block is " one " font or L-type, and fixed orifice is opened in the middle of grip block rounded, fixes, or open in surperficial semicircular in shape with hold-down support or sliding support, assembles mutually with sliding axle; The power supply access groove groove that is square, is connected with soft copper silk, and power supply is imported to fixture; The clamping face of one group of grip block clamps plate test coupon, be used for plate test coupon to stretch, or the clamping face of one group of grip block clamps mutually, is used for column type test specimen to compress.
Fixture of the present invention integrates clamping, electrode, cooling system function, designs simplification, and fixture is made by conductive material, and conductivity is high, has electrode function, and fixture is provided with cooling system, can adapt to extreme hyperthermal environments.
