薄壁铝合金整流罩成形工艺
Forming process of thin-walled aluminum alloy fairing
摘要
Abstract
To solve the problems of cracking,wrinkling,and low precision in aluminum alloy sheet metal parts formed at room temperature,and to achieve low-cost,high-precision forming of fairing components,a study was conducted on deep stretching and pressing forming processes of thin-walled,complex structural components made of low-plasticity,low-strength 2A11 aluminum alloy at room temperature.By combining field experiments and sheet metal forming principles,an analysis of the rubber pad forming process and steel die pressing forming for an aluminum alloy fairing with a wall thickness of 1.0-2.0 mm and a stretching ratio of 0.62 was performed.Through segmented forming and iterative parameter optimization,the influence of parameters such as stretching speed,pressurization rate,and lubrication conditions on the quality of the stretching process was investigated.The impact of the quenching process on the aluminum alloy pressing forming process was studied through heat treatment experiments.This research successfully achieved deep stretching forming of the aluminum alloy fairing with a wall thickness of 1.0-2.0 mm at room temperature,effectively suppressing wrinkling and cracking.Furthermore,the problem of cracking in the stiffeners during pressing was resolved by optimizing the solution heat treatment parameters(temperature:495-500 ℃,time:35-40 min).The results indicate that rubber pad forming combined with segmented parameter optimization significantly improves the forming quality of thin-walled aluminum alloy components,and precise control of the quenching process is key to achieving defect-free pressing of the fairing's stiffener surfaces.关键词
