Background technology
Develop rapidly along with space flight and aviation, automobile and electron trade, requirement for combination properties such as metal material high strength, lightweight, thermotolerances is more and more higher, various novel magnesium alloys, aluminium alloy, titanium alloy material arise at the historic moment, and the mechanical behavior under high temperature test of these novel alloys just becomes them and enters the important step that must carry out before the application.At present, high temperature tension test is comparatively ripe in metal material mechanics performance test field, and application surface is also wide, but high temperature compressed test is owing to only limit to the demand of above novel alloy material, its proving installation and imperfection.Possess the laboratory of high temperature tension test appointed condition for those, as long as develop the special-purpose high temperature compression verification anchor clamps of a cover coupling high temperature tension test machine and high temperature furnace at present, can carry out the high temperature compressed strength test of alloy material.Can save the expense of the high temperature compressed pilot system of special buying.
China utility model patent CN201220257563.5 " a kind of anchor clamps for test compound material at high temperature compression strenght " discloses a kind of anchor clamps for test compound material at high temperature compression strenght, it is characterized in that comprising seaming chuck, the seaming chuck cushion block, clamp body, the clamp body cushion block, the zigzag trapezoid block, these anchor clamps can be fixed the compression sample well, also can prevent splashing of sample behind the fail in compression, but this device also must assist platen up and down and the high temperature furnace of conventional compression clamp to realize compression experiment, more loaded down with trivial details, and the size of these anchor clamps requires than higher for the high temperature furnace inner wall space, is difficult to the dissimilar high temperature furnace of coupling.
Summary of the invention
The purpose of this utility model is exactly to overcome the defective that the high temperature compressed test fixture of current material exists, and a kind of material at high temperature compression strenght test fixture of simple in structure, function admirable is provided.
For achieving the above object, the material at high temperature compression strenght test fixture that the utility model is designed, comprise last platen and following platen for testing machine compression sample, its special character is: described upward platen suspends by last platen extension rod and is fixed on testing machine crossbeam below, described platen down is fixed on the tester base by adding high-base, described pass when going up platen and the work of following platen high temperature furnace up and down the opening of two ends setting stretch in high temperature furnace, move in tester base in opposite directions by the testing machine crossbeam, make the motion of the downward platen of platen, thereby finish high temperature compressed to sample.
Further, described following platen pressure-bearing plane extension is provided with annular enclosing, forms enclosure space when described last platen presses down and between the annular enclosing.Like this, can prevent that metal material from splashing at compressed sample fragment when causing destroying injures high temperature furnace inwall insulating brick, heating element or thermopair.
Further, the described platen extension rod top of going up is connected with the holder that testing machine crossbeam below arranges by latch, and the described platen extension rod bottom of going up is connected with last platen by latch.Like this, can replace with platen easily and go up the platen extension rod according to test situation.
Further, the described high-base that adds is the hollow cylinder structure, and described platen bottom down is provided with fixed bar, and described fixed bar is inserted in the hollow cylinder that adds high-base, and locatees by latch.Like this, can be according to platen fixed position under the test situation adjustment.
Further, described platen and the following platen employing exotic material Cr of going up
25Ni
18Make.Can guarantee that like this compression clamp carries out compression test under 1100 ℃, be fit to the compression test of most high temperature alloys.
Advantage of the present utility model is: designed material at high temperature compression verification anchor clamps are by arranging the platen extension rod and adding high-base, platen and following platen can compress in the sample of shorter size on having guaranteed, increased distance between testing machine crossbeam and the tester base, high temperature furnace can be arranged between testing machine crossbeam and the tester base, and last platen and following platen can stretch into high temperature furnace compression sample, have guaranteed test effect; In order to prevent that the compressed destruction of sample from causing the sample fragment to splash and injuring high temperature furnace inwall insulating brick, heating element or thermopair, extension arranges annular enclosing on following platen pressure-bearing plane, forms enclosure space when platen is pressed down and between the annular enclosing.The utility model is simple in structure, use safety, improvement cost is cheap, can be used as anchor clamps and is widely used in the Mechanics Performance Testing at high temperature of various metal materials.
Description of drawings
Fig. 1 is a kind of structural representation of material at high temperature compression strenght test fixture.
Each parts label is as follows among the figure: go up platen 1(wherein: go up platen extension rod 1.1); Following platen 2(is wherein: annular enclosing 2.1, fixed bar 2.2); Testing machine crossbeam 3(is wherein: holder 3.1); Add high-base 4; Tester base 5; High temperature furnace 6; Latch 7; Sample 8, testing machine screw mandrel 9.
