Technical Field

[0001] This utility model relates to the field of aluminum substrate testing technology, specifically an aluminum substrate tensile strength testing device. Background Technology

[0002] Aluminum products are manufactured from aluminum and other alloying elements. They are usually first processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then manufactured through processes such as cold bending, sawing, drilling, assembly, and coloring. The main metallic element is aluminum, and some alloying elements are added to improve the performance of aluminum materials. Aluminum processed products are widely used in aerospace, construction, transportation, electrical, chemical, packaging and daily necessities industries, etc., and its output ranks second only to steel among metal materials. Aluminum substrate generally refers to aluminum alloy materials without surface treatment.

This novel device, through the function of the limiting components, simultaneously limits the aluminum substrate body and, in conjunction with the magnifying detection structure, can quantify minute thickness changes of the pressurized aluminum substrate body. Furthermore, through the structural characteristics of the pressurizing device, it can be adapted to aluminum substrate bodies of different thicknesses, and for aluminum substrate bodies of the same thickness, the pressure can be adjusted according to processing requirements.

[0004] However, this device has the following shortcomings: while it can perform compressive strength testing on aluminum substrates, the testing can only detect the structural strength in the vertical direction and cannot detect the structure in the horizontal direction, thus limiting its effectiveness.
