摘　　要：阐述无需模具的逐次塑性成形研究。半球头工具直接对紫铜管进行逐次塑性成形为例 ,通过控制工具的运动轨迹 。This article carries out a research on successive plastic formation without dies.By taking the successive plastic formation of copper pipes with semispherical_headed tools as an example,it explores its formation mechanism and optimum formation conditions by controlling the tools' motion traces.

关 键 词：逐次塑性成形 包络面 工具轨迹 成形极限 异型管件 紫铜管
