| 摘 要： | 顶头形状设计是压力穿孔机理论研究的重要内容．减少穿孔力是相对提高穿孔机顶杆刚度．改善毛管偏心度的重要途径．根据压力穿孔过程中金属的变形特点．将变形区分成预穿孔区和穿孔延伸区．利用上限元法以最小穿孔力为目标．在穿孔延伸区中对顶头形状和变形锥长度进行了优化．确定了Ｋｏ的选取原则．中间实验验证了理论分析的正确性．

| Abstract: | In order to increase stiffness of piercing bar. Problems of decreasing piercing force are studied in the processes of press piercing. Some parameters of the piercing heads and piercing force are given by using UBE method. Calculating results are comparaed with the experiment results of industry production and good conclusions are obtained. |
