[0002] Endurance strength testing machines are widely used in fields such as materials science and mechanical engineering to evaluate the endurance performance of materials in high temperature environments. This type of equipment can not only simulate actual working conditions, but also provide accurate data support to help researchers better understand the behavioral characteristics of materials, thereby optimizing product design and production processes.
[0003] Existing endurance strength testing machines usually adopt a single heating chamber design, heat the sample through a built-in heating wire, and use a hydraulic cylinder or other drive device to apply a continuous load to complete the endurance strength test. Common methods include but are not limited to: (1) a single heating chamber with a single detection component, which is suitable for testing simple samples; (2) multi-point temperature control, by setting up temperature control systems for different areas in the heating chamber to achieve local temperature regulation.

The design of a single heating chamber limits the testing environment for multiple specimens at the same time, resulting in low testing efficiency; therefore, how to improve the versatility of the testing machine has become an urgent problem to be solved.

[0021] By adopting the above technical solution, a flange is formed at one end of the flow equalizing plate, so that the flow equalizing plate can enter the heating chamber more smoothly. Specifically, the flange can smoothly transition along the material guide surface, reduce friction resistance, avoid jamming, and thus improve the sliding stability and operation convenience of the partition plate.

Specifically, a shaft body 63 parallel to the first axis is fixedly connected to the partition plate 41.

In the direction from the heating box 3 to the fixed seat 51, each The guide plate 7 is tilted toward the side away from the other guide plate 7, so that the distance between the two guide plates 7 in the third direction gradually decreases from the fixing seat 51 to the side of the heating box 3, and the end of the guide surface 71 close to the through hole 321 smoothly transitions with the inner wall of the through hole 321, so as to guide the equalizing plate 61 to smoothly enter the through hole 321; when the partition plate 41 is in an open position, the distance between the partition plate 41 and the end of the guide surface 71 away from the heating box 3 can allow the equalizing plate 61 in the outward expansion position to pass along the first direction; One end of the flow equalizing plate 61 away from the partition plate 41 is bent toward the first material opening 322 and buckled inward to form a flange 611 , so that the flow equalizing plate 61 can slide into the through hole 321 more smoothly along the material guiding surface 71 .
[0038] The implementation principle of a durability testing machine according to an embodiment of the present application is as follows: when the heating chamber 31 needs to be divided into two heating zones 311, the driving component pushes the partition plate 41 into the heating chamber 31, so that the heating chamber 31 is divided into two heating zones 311 by the partition plate 41; when the two heating zones 311 need to be merged, the partition plate 41 is moved toward the side of the fixed seat 51; after the adjustment is completed, the specimen is placed in the heating zone 311, and then the driving cylinder 23 drives the push plate 22 to be pressed down to test the specimen.
