What will the application of precision parts processing in the aviation industry look like? as follows!
With the rapid development of the aviation industry, higher and higher requirements are placed on the semi-finished products of industrial aluminum profiles, especially for high-speed military and civil aircraft, which require the use of more complete semi-finished products, so as to make the structure of each component more reasonable and ensure better structural quality. Light, high strength and rigidity, while greatly reducing the number of components, reducing the cost of propeller assembly, joint and maintenance. Ensure a perfect and beautiful surface (good sealing, no seams, no deformation, etc.).
(1) Large-scale industrial aluminum profiles are particularly important structural parts on aircraft, and the profiles are required to have excellent mechanical properties. Therefore, aluminum profiles must be custom-made for industrial aluminum alloy profiles by extrusion of hard aluminum or super-hard aluminum alloys.
(2) Since industrial aluminum profiles are used as structural parts of key parts of aircraft, good comprehensive performance and uniform organization are required, especially for finished products. The coarse-grained ring defect in the quenched products after extrusion is difficult to avoid, and it is also one of the research topics of the specific gravity scale of Minde aluminum 868 profiles for which extrusion workers all over the world have struggled for decades with little success.
(3) For aluminum profiles such as cross-shaped girders and comb-shaped joint plates, on the one hand, their cross-sectional area is large, which often makes the extrusion deformation coefficient relatively small, and on the other hand, they must bear a large load in the lateral and height directions. Therefore, it is required to have high mechanical properties in the lateral and vertical directions. This contradiction is often an important reason for the scrapping of aluminum profiles.
