[0002] Aluminum alloy components, due to their lightweight, high strength, and excellent corrosion resistance, occupy an important position in various industries such as aerospace, automotive manufacturing, and building decoration. As key components, their quality and performance have a decisive impact on the safety and reliability of the final product. Especially in the core process of material quality control, tensile testing machines, as a key piece of equipment for evaluating the mechanical properties of aluminum alloy components, have gradually revealed significant limitations when handling aluminum alloy components of different shapes, sizes, and application requirements.

[0003] Specifically, aluminum alloy fittings refer to aluminum-based alloy products manufactured through specific processes, widely used in applications requiring high strength and lightweight design. To ensure these fittings can withstand the expected stress loads in actual use environments, tensile testing is an essential quality control step. Existing tensile testing equipment, such as the aluminum alloy solid bar tensile testing machine disclosed in utility model patent CN 116558965 A, while effectively avoiding damage caused by metal debris friction against the clamps and extending the equipment's lifespan, lacks testing capabilities under varying temperature conditions. This means it cannot perform tensile tests on aluminum alloy fittings at different operating temperatures, thus limiting the comprehensiveness and accuracy of the test results.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need an innovative tensile testing machine for aluminum alloy components. This equipment should be able to perform tensile tests under different temperature conditions to improve the comprehensiveness and reliability of test results, while better meeting specific production or usage needs and providing strong support for the sustainable development of related industries.

[0028] The heating module 3 is connected to the side wall of the test chamber 1 through a horizontal adjustment module, and the pressure sensing module 2 is connected to the top of the test chamber 1 through a vertical lifting structure.

[0029] First, the aluminum alloy component to be tested is placed in the clamping seat 4 between the mounting base and the pressure sensing module 2, and then firmly fixed using the clamping assembly.

Several movable rods 6 are connected to both sides of the mounting frame 7. Several sliding grooves 5, adapted to the movable rods 6, are formed on both sides of the inner wall of the test chamber 1. Specifically, the design of the heating module 3, including the mounting frame 7 and the heating plate 9 bolted to one side of the mounting frame 7, with several movable rods 6 connected to both sides of the mounting frame 7 and several sliding grooves 5 adapted to the movable rods 6 on both sides of the inner wall of the test chamber 1, allows the heating module 3 to be horizontally adjusted along the sliding grooves 5 using the movable rods 6. This allows for adjustment of the position of the heating plate 9 according to the specific size and position of the aluminum alloy fitting, ensuring uniform heating. Simultaneously, the design of the mounting frame 7 enhances the overall stability and adjustability of the heating module 3, improving the accuracy and reliability of the test results.

The drive motor 18 drives the bidirectional lead screw 17 to rotate, causing the two clamping plates 15 to move inward or outward synchronously, thereby firmly clamping aluminum alloy parts of different sizes, significantly improving the adaptability and operating efficiency of the equipment.

[0037] This solution includes the following workflow:

[0038] When using this aluminum alloy component tensile testing machine, the aluminum alloy component to be tested is first placed in the clamping seat 4 between the mounting base and the pressure sensing module 2, and then firmly fixed using the clamping assembly.

Then, the pressure sensing module 2 is moved by controlling the vertical lifting structure to apply tensile force to the aluminum alloy parts until they break or reach a predetermined stress value. Throughout the process, the tensile force data is recorded in real time by the pressure sensing module 2.

[0039] The beneficial effects of this design are as follows: First, the design of the mounting frame 7 and heating plate 9 of the heating module 3, as well as the moving rod 6 and slide 5, enables precise horizontal adjustment of the heating module 3, ensuring uniform heating and thus more accurately simulating temperature conditions in actual application environments.

The lifting cylinder 10 and guide rod 11 in the vertical lifting structure ensure the accuracy and stability of the pressure sensing module 2 during the application of tension, ensuring the reliability of the test data. In addition, the design of the bidirectional lead screw 17, clamping plate 15, and the crossbar 14 and slider 13 connected to its bottom inside the clamping seat 4, combined with the moving groove 12, enables automated centering adjustment of the clamping plate 15, allowing the two clamping plates 15 to move synchronously inward or outward, firmly clamping aluminum alloy parts of different sizes, significantly improving the adaptability and operational efficiency of the equipment.
