[0045] Subsequently, during the testing process, the resistance wire inside the heating ring 6 was energized and heated evenly, providing a stable high-temperature environment for the composite material body placed in the central area, ensuring the accuracy of the high-temperature resistance test. Simultaneously, the positioning inclined plate 17 at the bottom of the placement dish positioned and fixed the composite material body, preventing displacement during the high-temperature test and ensuring the reliability of the test results. After the composite material body reached the rated heating time, the motor 2 was restarted to rotate in the reverse direction. The output of the motor 2 drove the second threaded screw 15 to rotate, and the second threaded sleeve 16 moved along the first guide post 8 under threaded transmission. This movement was achieved through the inclined plate 17, the second guide sleeve 19, and the fixed... The fixed frame 7 drives the sealing door 4 to open automatically along the door groove 5, avoiding manual contact with the high-temperature area and improving the safety of equipment use. At the same time, the first helical gear 12 on the second threaded screw 15 meshes with the second helical gear 14, causing the first threaded screw 10 to rotate. Under the guidance of the second guide column 9, the first threaded sleeve 11 drives the placement dish to rise smoothly to the outside of the heating ring cover 6 through the bending column 20, which facilitates the operator's work of taking the composite material body. The whole process is realized through automated control, reducing human operation error, improving detection efficiency, and further ensuring the safety of operators, demonstrating the advantages of high equipment safety performance and convenient operation.
