摘　　要：以AA6016变形铝合金为研究对象,对其采取了不同的热处理,得出冲压成形性能最佳的固溶和时效处理方式,并研究了拉深速度和压边力等工艺参数对板料成形性能的影响。结果表明,AA6016铝合金冲压成形性能最佳热处理方式为540℃保温40 min的固溶处理及160℃预时效10 min处理,可提高其成形极限,改善AA6016铝合金的成形性能;室温拉深时当拉深速度为3 mm·min-1,压边力大小为1.2 N·mm-2时,拉深成形性能良好,可以得到极限拉深比为1.7,为AA6016铝合金在汽车车身方面的应用提供了理论依据。The solid solution and aging treatment for the optimal stamping properties of the AA6016 deformation aluminum alloy were carried out by using different heat treatment processes,and the effects of drawing speed,blank holder force and other parameters on the formability of sheet metal were studied. The results show that the solid solution treatment heat preservation for 40 min at 540 ℃ and pre-aging at 160 ℃ for 10 min is the best heat treatment mode for the stamping formability of AA6016 aluminum alloy,which can effectively improve the forming limit and the formability of AA6016 aluminum alloy; at room temperature,when the drawing speed is 3 mm·min^-1 and the blank holder force is 1. 2 N·mm^-2,a better drawing performance can be obtained,and the limit drawing ratio is 1. 7,which provides a theoretical basis for the application of AA6016 aluminum alloy in automobile body.
