Abstract

The invention discloses a method for producing an aluminum alloy plate. The method comprises the following steps of: preparing materials: uniformly mixing 0.4% of Si, 0.6% of Fe, 4% of Cu, 0.1% of Mn, 0.22% of Cr, 0.06% of Ti, 2% of Mg, 0.2% of Zn and the balance of Al; processing the prepared materials into a cast alloy ingot; heating and hot-rolling the cast alloy ingot to obtain a blank; cold-rolling the blank; carrying out intermediate annealing; cold-rolling; carrying out intermediate annealing; drawing and straightening; cold-rolling; thermally treating; and straightening and sharing to obtain the aluminum alloy plate with the preset thickness. According to the invention, a cold-rolling process is carried out in two steps, the intermediate annealing is carried out after the cold-rolling so as to eliminate work hardening and recover metal plasticity, and finally, the thermal treatment is carried out to increase the performance of the aluminum alloy plate to meet a requirement so as to obtain the qualified aluminum alloy plate, so that the finished product rate of the aluminum alloy plate is increased.

Description

technical field [0001] The invention relates to the technical field of sheet material processing for aviation, in particular to a production method of aluminum alloy sheet material. Background technique [0002] The aerospace industry is an industry that develops and produces spacecraft, space vehicles and their equipment and ground support equipment. It is an important part of the national defense science and technology industry, an important industry of the national defense industry, and one of the comprehensive high-tech industries. Due to the rigor of the aerospace industry, the quality requirements for the materials used are very high. Aluminum alloy sheets with a thickness of 0.3mm are often used in aerospace, but the existing aluminum alloy sheets with a thickness of 0.3mm cannot be produced. Instead, it is replaced by other alloy products, which is not conducive to the improvement of product performance. [0003] Existing methods for producing aluminum alloy sheets:...
