利用纯铝1060圆坯,改变旋轮与芯模之间的间隙,旋压成形获得曲母线型零件,研究了间隙对径向应变和厚度的影响,并进行了缺陷分析。结果表明:间隙大小对工件成形质量有直接关系。当间隙值较大时,工件容易起皱;当间隙值较小时,工件易破裂。 The pure aluminum 1060 round billet was used to change the gap between the rotating wheel and the mandrel. The curved part was obtained by spinning. The effect of the gap on the radial strain and thickness was studied and the defect analysis was carried out. The results show that the gap size is directly related to the quality of workpiece forming. When the gap value is large, the workpiece is easy to wrinkle; when the gap value is small, the workpiece is easy to break.
