Abstract
The utility model provides a cramping utensil for testing alloy material high temperature compression performance, belongs to test instrument and makes technical field, adoptions in pressure disk, go up high temperature cramping utensil, down high temperature cramping utensil and down the pressure disk constitute, the last aligning ring flange of going up the pressure disk has decurrent axial blind hole, the blind hole has the internal thread, it has the external screw thread to go up high temperature cramping utensil top, upward the high temperature cramping possesses and last aligning ring flange threaded connection, the lower aligning ring flange of pressure disk has ascending axial blind hole down, and insert down in the blind hole of aligning ring flange lower high temperature cramping utensil bottom, high temperature cramping utensil is under last high temperature cramping utensil down. During the use, the upper grip that will go up pressure disk and compression test equipment links to each other, and the direct facial features of going to the bottom with compression test equipment of lower pressure disk is inlayed, high temperature cramping utensil decline adjustment in, make the interval of upper and lower high temperature cramping between possessing be greater than the sample the height can, alloy material's under the high temperature condition compression test carries out afterwards. The utility model has the advantages of it is high temperature resistant, the test result accuracy is high.
Description
Technical field
This utility model belongs to test instrunment manufacturing technology field, is the cramping tool of a kind of beta alloy material at high temperature compression performance.
Background technology
Compression test is to measure material mechanical property test under axial static pressure effect, is one of the basic skills of alloy material mechanical test, and compressive property is the detection superplastic important method of alloy material.In order to realize the superplasticity of alloy material, high temperature compressed for this utility model fixture is used in conjunction with each other with compression test equipment, analyzes alloy material mechanical property at high temperature by test compression intensity and change.
The technology of existing associated compression test, it mostly is the pressure processing of sheet metal, rolling such as sheet material, the forging of metallic article, if appearance flexing failure phenomenon too early in high-temperature pressurizing process of the test, then increase the waste that alloy material is unnecessary, and also need to carry out high temperature compressed test repeatedly to having a strong impact on of eliminating that result of the test causes by too early flexing failure phenomenon, not only lost time but also added the number of times of test operation, test operation process had been caused the impact of a lot of inconvenience.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of cramping for beta alloy material at high temperature compression performance to be had.
It is to use the cramping that upper platen, upper high temperature clamp tool, lower high temperature clamps tool and pressing disc is constituted for beta alloy material at high temperature compression performance to have that the present invention solves the scheme of technical problem, upper platen is made up of upper centring ring flange and upper locating flange dish, upper centring ring flange is in upper locating flange tray bottom, both use, and bolt is fixing to be connected, upper centring ring flange has downward axial blind hole, blind hole has female thread, it is column that upper high temperature clamps tool, external screw thread is arranged at top, and upper high temperature clamps tool and threadeds with upper centring ring flange；Pressing disc is made up of center downward regulating ring flange and lower locating flange dish, center downward regulating ring flange is on lower locating flange dish, and both use, and bolt is fixing to be connected, and center downward regulating ring flange has axial blind hole upwards, it is column that lower high temperature clamps tool, and bottom is inserted in the blind hole of center downward regulating ring flange；Lower high temperature clamps tool and clamps the underface of tool at upper high temperature.
During use, upper platen is connected with the upper grip of compression test equipment, pressing disc is mutually the most embedding with the bottom surface of compression test equipment, to be connected firm time, by the manual operation screen being connected with compression test equipment, in adjustment, high temperature clamps tool decline, makes upper and lower high temperature clamp the height more than sample of the spacing between tool, carries out the compression test of alloy material under hot conditions subsequently.
Regulation of mental activities ring flange is fixing with locating flange dish employing bolt to be connected, by upper centring ring flange and center downward regulating ring flange position adjustment, it is possible to makes upper and lower high temperature clamp the dead in line of tool, improves the accuracy of result of the test.
Upper locating flange dish has the most through upper connecting hole, and lower locating flange dish has the most through lower connecting hole, is used for connecting water nozzle, forms cooling water recirculation system, stops heat to be delivered to compression test equipment.
Operationally, upper and lower high temperature clamps tool and will not deform under the high temperature conditions this utility model, has resistant to elevated temperatures advantage, and is difficult to be destroyed during work；It is small sample that upper and lower high temperature clamps the folded sample of tool, saves the utilization rate of alloy material；Localized contact at high temperature heating conditions lower clamp Yu sample can avoid causing bigger frictional force, the most just can obtain more real compressive strength, improve the accuracy of result of the test, and test is served the biggest help；Meanwhile, the generation flexing that can effectively prevent sample too early before obtaining its true compressive strength lost efficacy；Upper and lower platen is provided with the most through connecting hole, is used for connecting water nozzle, forms cooling water recirculation system, it is to avoid compression clamp causes the damage of parts owing to temperature is too high in high temperature compressed process of the test.
