Seamless bending processing technology for aluminum alloy sections

Abstract

The invention relates to a hardware bending technology, and in particular to a 90-degree seamless bending processing technology for aluminum alloy sections. According to the 90-degree seamless bending processing technology for the aluminum alloy sections, the aluminum alloy sections are bent into a right angle in the mode that one face of the mutual perpendicular two faces of the aluminum alloy sections is compressed along the deformation top point and the other face is stretched along the deformation top point. According to the 90-degree seamless bending processing technology for the aluminum alloy sections, an extrusion mode of enabling the bent parts of the aluminum alloy sections to be even in stress and deformation is adopted for formation, and then extrusion trimming is cut off; the characteristics that the materials of aluminum products are good in fluidity and malleability are utilized, the mode that formation is achieved through die extrusion in three steps is adopted, the 90-degree seamless bending effects of the aluminum alloy sections with good appearance, size and intensity can be achieved, reproducibility is good, and the high standard requirements of the aspects of the appearance, the size and the intensity of television outer frames, tablet personal computer outer frames, 3C consumption products and high-end decorative frames are met.

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. Invention content: [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. [0...
