中文摘要：针对铝合金、铜合金等有色金属薄板在弯曲成形过程中表面容易划伤、产生塑性压痕，以及弯曲模具不可加工厚度不一的问题，通过分析影响板料弯曲成形工艺的主要因素，提出了采用将材料流入方式由滑动变为滚动成形的策略，并给出了具体的模具结构和设计要点。
英文摘要：Aimming at the problems of surface quality for U- type stamping bending forming of aluminum alloy, titanium alloy and other nonferrous sheet metal, such as surface contact impression, surface scratch and difficultly processing different thickness sheet metal, by analyzed the influence factors of sheet metal bending forming, the new strategy was put forward adopted rolling inflow method instead of sliding inflow. The concrete die structure and corresponding design keypoints were presented.
