[0002] The mechanical properties of metallic materials at high temperatures directly affect their performance and reliability under extreme conditions. High-temperature tensile testing, as a crucial method for evaluating the high-temperature performance of materials, can obtain key mechanical parameters such as tensile strength, yield strength, elongation, and reduction of area under high-temperature conditions, providing a scientific basis for material research and development, quality control, and engineering applications. The core testing process for metallic materials includes multiple steps such as sample preparation, sample heating and holding, tensile testing, and test data acquisition. The tensile test is conducted using a high-temperature tensile testing machine.

[0051] Example 1

[0052] Please see Figure 1 , Figure 1This is a schematic diagram of a sample feeding device for high-temperature stretching of metallic materials. It includes a sample feeding assembly 1, a sample heating assembly 2, a sample stretching assembly 3, a post-fracture data sampling assembly 4, and a post-fracture sample packaging assembly 5. The sample feeding assembly 1 includes multiple parallel conveyor rails 17, preferably two parallel conveyor rails 17, designated as a first conveyor rail and a second conveyor rail. The first and second conveyor rails cooperate to improve sample flow efficiency. For example, each of the first and second conveyor rails has a sample box 12. When the sample box 12 on the first conveyor rail moves from the initial position 171 to the working position 172, the sample box on the second conveyor rail moves from the working position 172 towards the initial position 171. When there are urgent target samples requiring priority processing... The urgent target sample can be directly used as the next sample loading task on the transfer rail from the working position 172 to the initial position 171 without affecting the processing program of the currently recorded target sample. This not only completes the processing of the urgent target sample, but also reduces the probability of program running disorder and improves the efficiency and adaptability of sample flow. A first robotic arm 11 is provided at one end of the transfer rail 17, and the sample heating component 2 is located on one side of the transfer rail 17. A pull rod transfer component 6 is provided on the other side of the transfer rail 17 relative to the sample heating component 2. The installation positions of the sample heating component 2 and the pull rod transfer component 6 are adapted to the first robotic arm 11. That is, the sample heating component 2 and the pull rod transfer component 6 are both set along the end of the transfer rail 17 close to the first robotic arm 11.

[0053] In one embodiment, please refer to Figure 2 The conveyor rail 17 has an initial position 171 at the end furthest from the first robotic arm 11 and a working position 172 at the end closest to the first robotic arm 11. A sample box 12 that can slide along its length is mounted on the conveyor rail 17. A first sensor 15 and a second sensor 16 are respectively provided at both ends of the conveyor rail 17. The first sensor 15 is located at the end where the initial position 171 is located. The second sensor 16 is located at the end where the working position 172 is located. The first sensor 15 and the second sensor 16 include, but are not limited to, infrared sensors, pressure sensors, etc.

[0054] In one embodiment, please refer to Figure 2 The first scanning component 14 is also installed on the conveyor rail 17.

The second barcode scanning component 132 and the sample clamping mechanism 133 are both fixed on the second base 131. The second barcode scanning component 132 is located between the first robotic arm 11 and the sample clamping mechanism 133.

[0056] In one embodiment, please refer to Figure 3 and Figure 4 The first robotic arm 11 includes a first base 110, a first connecting rod 112, and a first clamping member 111. The first clamping member 111 is hinged to one end of the first connecting rod 112, and the other end of the first connecting rod 112 is fixed to the first base 110. The first clamping member 111 is used to clamp the target sample to be tested. The sample clamping mechanism 133 includes a first rotary motor 1331, a second clamping member 1332, and a first slide module 1333. The second clamping member 1332 is fixed to one end of the first slide module 1333, which is away from the first base 110, and is used in conjunction with the first rotary motor 1331. The second clamping member 1332 can rotate under the action of the first rotary motor 1331.

[0057] In one specific embodiment, please refer to Figure 4 The target sample is a metal sample with screws at both ends. The target upper pull rod 61 and target lower pull rod 62 in the pull rod transfer assembly 6 each have a thread at one end that matches the screw of the target sample. When the sample box 12 reaches the predetermined position, the second sensor 16 sends an indication signal to the controller. Based on this indication signal, the system controls the first robotic arm 11 to transfer the target upper pull rod 61 from the pull rod transfer assembly 6 to the second clamping member 1332 of the sample clamping assembly 133. The threaded end of the target upper pull rod 61 is away from the second clamping member 1332. Then, the first clamping member 111 of the first robotic arm 11 clamps the target sample from the sample box 12 onto the target upper pull rod 61. At the pull rod 61, the screw of the target sample is aligned with the thread of the target upper pull rod 61. The first rotary motor 1331 is controlled to drive the target upper pull rod 61 on the second clamping member 1332 to rotate, thereby connecting the target upper pull rod 61 with the target sample. Finally, the first robotic arm 11 is controlled to continue to clamp the target lower pull rod 62 from the pull rod transfer assembly 6 to the target sample, and the thread of the target lower pull rod 62 is aligned with the screw at the other end of the target sample. The first rotary motor 1331 is controlled to drive the target upper pull rod 61 on the second clamping member 1332 to rotate, thereby connecting the target lower pull rod 62 with the target sample, thus completing the loading of the target sample.

[0058] In one embodiment, please refer to Figure 5The sample heating assembly 2 includes a heating furnace 21, a heating base 22, and a conveying rail 23. The heating base 22 has multiple heating stations 220 for placing the heating furnace 21. The conveying rail 23 has a second robotic arm 24 that reciprocates along it. Figure 13 As shown, the second robotic arm 24 includes a second clamping member 241, a third base 243, and a second connecting rod 244. One end of the second clamping member 241 is hinged to the second connecting rod 244, and the other end of the second connecting rod 244 is fixed to the third base 243. The second clamping member 241 is adapted to the heating furnace 21. A second power supply 242 is also provided inside the second clamping member 241. The second power supply 242 is adapted to the second power supply hole 2114 on the heating furnace 21 so that the second robotic arm 24 can continuously supply power to the heating furnace 21 during the transfer of the heating furnace 21. By adding the second power supply hole 2114 on the heating furnace 21, the heating furnace 21 can still keep the target sample warm after it leaves the heating station 210. This ensures that when the number of heating furnaces is greater than the number of tensile testing machines in the high-temperature tensile testing of a large number of metal materials, the metal materials are kept warm during the transfer from the heating base to the tensile testing machine with the heating furnace, thus ensuring the experimental effect of large-scale application.
