研究了柱面多点分段成形时板材易于产生的缺陷及其产生原因。在分段成形后，试件能否与目标形状相吻合是衡量板材成形效果的重要标准。基于板材的变形规律，通过成形实验探讨了有重叠区与无重叠区的成形方法、影响区形变协调成形方法和多道分段成形方法。
The defects of the easy-to-produce plate when the multi-point cylinder is formed and the causes are also studied. After the segmentation is formed, the specimen can match the shape of the target is an important measure of sheet metal forming an important criterion. Based on the deformation law of sheet metal, the forming method with overlapping area and non-overlapping area, the coordinated deformation method of forming area in influence area and the multistage forming method are discussed through forming experiments.
