在分析筒形件强力旋压成形特点及其变形规律的基础上,对铝合金轮毂强旋成形工艺、缺陷成因进行了研究,分析旋轮形状、旋轮进给率、壁厚减薄率、多旋轮之间的错距等工艺参数对成型改善的影响,对表面失稳、旋裂、折叠、表面起皱、贴模性不好等缺陷的成因进行了分析。对铝合金轮毂的强旋加工、优化工艺参数提供有效方法和可靠依据。 On the basis of analyzing the forming characteristics and deformation rules of cylindrical spinning, the strong spin forming process and the cause of defects of the aluminum alloy wheel hub were studied. The shapes of the rotating wheel, the feed rate of the rotating wheel, the thinning rate of the wall thickness, The error between multi-roller and other process parameters on the improvement of molding, the instability, spin-splitting, folding, surface wrinkling, die-casting and other defects of the causes were analyzed. The aluminum alloy wheels strong spin processing, optimization of process parameters provide an effective method and reliable basis.
