【摘要】：对工业纯铝1060板料进行单点增量成形极限实验研究,比较了圆锥形件各部位厚度的分布情况。实验发现,当成形角增大时,成形件上部会出现厚度严重变薄的减薄带,并且破裂容易出现在减薄带上,影响板料成形极限。用最大成形角表征单点增量成形过程中的成形极限,分析了不同参数对板料最大成形角的-影响,发现层间距会影响板料的最大成形角,而工具头周向进给速度对最大成形角的影响不大,不同形状的成形件其最大成形角也不相同。最后通过实验获得了1 mm厚度铝板的成形极限曲线(FLC)。
[Abstract]:A single point incremental forming limit experiment was carried out on industrial pure aluminum 1060 sheet metal, and the distribution of the thickness of each part of the conical part was compared. The experimental results show that when the forming angle increases, the thickness of the upper part of the forming part will be thinned seriously, and the fracture will easily appear in the thinning zone, which will affect the forming limit of sheet metal. The maximum forming angle is used to characterize the forming limit in the process of single point incremental forming. The influence of different parameters on the maximum forming angle of sheet metal is analyzed. It is found that the interval between layers will affect the maximum forming angle of sheet metal. However, the circumferential feed velocity of the tool head has little effect on the maximum forming angle, and the maximum forming angle is also different for different shapes of forming parts. Finally, the forming limit curve (FLC).) of 1 mm thick aluminum plate is obtained by experiment.
