Description

【Technical field】: [0001] The invention relates to a method for manufacturing auto parts materials, in particular to a method for manufacturing high-strength aluminum alloy wheel rim materials for automobiles. 【Background technique】: [0002] The rim is the part that fixes and installs the tire in the wheel. It belongs to the automobile security parts. The rim structure has two-piece, three-piece, four-piece, five-piece, etc., and the most commonly used ones are two-piece and three-piece. Rims can be divided into steel rims and aluminum alloy rims according to their manufacturing materials. At present, steel rims are commonly used at home and abroad. These steel rims are manufactured by section steel processing or plate rolling. The material grades are 12LW-GB11262-89, BG380CL, etc., among which the tensile strength of the 12LW-GB11262-89 material is σ b It is 355~470MPa, elongation>30%. Compared with steel rims, aluminum alloy rims have absolute advantages in terms of ...
