Abstract

The invention discloses a production method of an aluminum alloy base material for a 5052 alloy door plate, and relates to the technical field of aluminum alloy production. The method comprises the following steps that an aluminum alloy finished product is prepared from the following raw materials, by mass, less than 0.10% of Si, less than 0.35 of Fe, less than 0.10% of Cu, less than 0.10% of Mn,2.30-2.60% of Mg, 0.15-0.35% of Cr, 0.01-0.05% of La+Ce, less than 0.10% of Zn, the total content of impurities is below 0.15%, and the balance is Al; the aluminum alloy finished product is subject toannealing treatment, under the protection of inert gas, the temperature is controlled to be 300-320 DEG C in a box-type furnace, and the aluminum alloy finished product keeps warm for 2-4 hours and then cooled with the furnace at the speed of 20-40 DEG C per hour; and the aluminum alloy finished product is subject to stretching bending straightening treatment. According to the production method,the problem that an existing door-used aluminum alloy base material is prone to wrinkling after stamping is solved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy production, in particular to a production method of a base material for an aluminum alloy door panel. Background technique [0002] With the rapid development of science and technology and industrial economy, the demand for aluminum alloy structural parts is increasing, such as the processing of aluminum alloy doors and windows. The aluminum alloy door is a door frame component made of surface-treated aluminum alloy profiles, and then assembled with connectors, sealing materials and hardware accessories. my country's construction industry has developed rapidly in recent years, and the market demand for building door panel materials has gradually increased. Aluminum alloy has the characteristics of light weight, medium strength, easy forming, and corrosion resistance. At the same time, compared with traditional wooden door panels, aluminum alloy door panels have the advantages of fire resis...
