Abstract Industrial metal spinning depends on costly trial-and-error when introducing new products. However, a recently developed flexible spinning setup allows a new form of process operation similar to raising by hammering: two rollers on either side of the rotating workpiece apply a couple to deform it locally whilst moving towards its edge. This paper presents this configuration for the first time and develops and verifies an upper bound yield-line model to design stable tool-paths that avoid wrinkling. Raising by spinning is shown to be feasible and more stable than conventional spinning, paving the way for automatic production of deep axisymmetric shapes.

通过旋转提高

摘要 工业金属旋压在推出新产品时依赖于代价高昂的反复试验。然而，最近开发的灵活旋压装置允许采用类似于锤击提升的新工艺操作形式：旋转工件两侧的两个辊子施加一对辊子使其局部变形，同时向其边缘移动。本文首次介绍了这种配置，并开发和验证了上限屈服线模型，以设计避免起皱的稳定刀具路径。与传统旋压相比，旋压提升是可行且更稳定的，为自动生产深轴对称形状铺平了道路。
