Embodiment Construction

[0021] The present invention will be further described below in conjunction with drawings and embodiments.

[0022] Such as Figure 1-Figure 3 As shown, the water-cooled fixture for high-temperature fatigue test of metal plate samples of the present invention mainly includes: chuck 1, groove 2, hole 3, bolt 4, extension shaft 5, wrench 6, external thread 7, water cooling device 8, internal thread 9. Water hole 10, spare cap 11, nut 12, etc. The specific structure is as follows:

[0023] There is a slot 2 in the center of the chuck 1, holes 3 are drilled symmetrically on both sides of the chuck 1 to place the bolt 4, the chuck 1 is connected with an extension shaft 5, and a wrench 6 is processed on the extension shaft 5. The function of the wrench 6 is to facilitate placement Wrench, external thread 7 is processed at the end of the extension shaft 5, internal thread 9 is processed at the end of the water cooling device 8 to connect the extension shaft 5, and a water hole 10 is...

Abstract

The invention relates to material testing equipment, in particular to a water-cooled jig for high-temperature fatigue testing of metal plate samples. The fixture is equipped with a chuck, an extension shaft and a water cooling device. There is a groove in the center of the chuck for placing a plate sample. The bolts pass through the holes on the chuck and clamped with the nuts; the extension shaft is connected with the water cooling device through threads, and the water cooling device is provided with a water hole for cooling water. The invention solves the problems of clamping ability and cooling effect of existing fixtures, not only can realize the axial fatigue test of metal plate samples under high temperature environment, but also can ensure the clamping force under high temperature and has good water cooling effect .

Description

technical field [0001] The invention relates to material testing equipment, in particular to a water-cooled jig for high-temperature fatigue testing of metal plate samples. Background technique [0002] Fatigue testing plays an important role in evaluating the structural integrity of metal components. In a high temperature environment, metal materials are usually processed into threaded rod-shaped specimens for fatigue tests. The fatigue test technology for rod-shaped specimens is now mature, but for brittle materials that are not suitable for processing threads and metal materials that are not suitable for processing into rod-shaped samples due to the small size of the original ingot, it is necessary to process the material into a plate-shaped test piece. Perform fatigue test. For ordinary plate-shaped specimen fixtures, when in a high-temperature environment, the stress relaxation caused by creep will reduce the clamping force of the bolts and cause clamping failure. In...
