[China Aluminum Industry Network] aluminum alloy reducer material knowledge: A classification of aluminum alloy profiles According to incomplete statistics, the current use of aluminum alloy profiles around the world in more than 13000kt / a, specifications of the species up to 5000 () more than. The scientific classification of aluminum alloy profiles is conducive to the scientific and rational selection of production processes and equipment, the correct design and manufacture of tooling, and the prompt handling of the technical problems and production management of the extrusion plant.
According to the purpose of use or use according to use or use characteristics, aluminum alloy reducer material aluminum alloy profiles can be divided into general profiles and special profiles. Special profiles can be divided into:
(1) Aerospace aviation profiles: such as integral ribs, I-beams, wing girders, comb profiles, hollow beam profiles, etc., are mainly used as force structural components for aircrafts, spacecrafts, and other spacecraft, as well as helicopter heterotypics. Hollow rotor girders and 'runway plates'.
(2) Profiles for vehicles: Mainly used as important stress components and decorative parts for high-speed trains, subway trains, light rail trains, double-decker buses, luxury buses, and trucks and special vehicles.
(3) Profiles for warships and weapons: Mainly used for the overall structure of ships, naval vessels, aircraft carriers, motorboats, speedboats, hydrofoil superstructures and decks, partitions, floors, tanks, armored vehicles, and personnel carriers. Force components, shells of rockets and medium and long-range missiles, shells of torpedoes, water bodies, etc.
(4) Profiles for electrical and electronic appliances, household appliances, post and telecommunications, and air-conditioner radiators: mainly used as housings, heat-dissipating components, etc.
(5) Profiles for energy industries such as petroleum, coal, and electricity, and machinery manufacturing industry: Mainly used as piping, brackets, mine carriages, transmission grids, busbars, and motor housings and various mechanical components.
(6) Profiles for transportation, containers, reefer containers, and roads and bridges: Mainly used for packing boards, springboards, container frames, frozen profiles, and bridge decks.
(7) Profiles for civil construction and agricultural machinery: such as doors and windows for windows and doors of civil buildings, decorative parts, fences and large building structures, glass and aluminum alloy curtain wall profiles, and agricultural irrigation device parts.
(8) other uses of profiles: such as sports equipment, diving boards, furniture structure profiles. b According to the characteristics of shape and size change Aluminum alloy reducer material according to shape and size change characteristics, profiles can be divided into constant profile profiles and variable profile profiles.
Constant section profiles can be divided into general solid profiles, hollow profiles, wall profiles and building doors and windows profiles, as shown in Figure 1 to Figure 7; variable profile profiles can be divided into stage variable sections and gradient section profiles, as shown in Figure 1-8. Show.
The design principle of aluminum alloy profile section The aluminum alloy reducer material is produced by the extrusion method. It is a method to save metal and produce high efficiency. However, it is influenced by many factors, and it must be taken into consideration when designing the profile section. The possibility of extrusion. The following discusses several major factors in profile section design.
