Aluminium alloy section bar seamless bending machining process

Abstract

The invention relates to a hardware bending process, in particular to the process used for aluminium alloy section bar 90-degree seamless bending machining. The aluminium alloy section bar 90-degree seamless bending machining process is that two perpendicular surfaces of an aluminium alloy section bar are bent into a right angle by compressing one of the surfaces and stretching the other surface along deformation vertexes of the surfaces. According to the aluminium alloy section bar 90-degree seamless bending process, the aluminium alloy section bar is squeezed and molded adopting a squeezingmethod making force-bearing and deformation of bending portions of the aluminum alloy section bar be uniform, and then squeezed trimming is cut. By means of the aluminium alloy section bar fabrication90-degree seamless bending process, the characteristics of aluminium materials of being good in fluidity and ductility are utilized, a three-step mold squeezing molding method is adopted, the aluminium alloy section bar fabrication 90-degree seamless bending effect with the appearance, size and strength being all good can be obtained, furthermore, the reproducibility is quite good, and the high standard requirements for the aspects of the appearance, size and strength of television outer frames, flat computer outer frames, 3C consumption products and high-grade decorative frames can be fullymet.

Description

technical field [0001] The invention relates to a metal bending process, in particular to a process for 90° seamless bending of aluminum alloy profiles. Background technique [0002] Existing aluminum alloy profile aluminum frame, such as figure 1 As shown, it is generally assembled by four aluminum alloy profiles, and there will be an assembly seam at each corner of the assembly, which is very unsightly and difficult to control the size. The molded bending process is used for one-time molding. Wrinkles and cracks often occur at the bending place, and the product qualification rate is very low, especially for products with high requirements on size and appearance, such as TV frames and tablet PCs. Frames and 3C consumer products simply cannot meet the high standards of consumers. Contents of the invention [0003] The object of the present invention is to provide a process for 90° seamless bending of aluminum alloy profiles to overcome the deficiencies of the prior art. ...
