| 摘 要： | 薄壁管冷弯成形过程中最常见的缺陷有管坯内侧失稳起皱、外侧减薄破裂,为获得质量良好的某车用水冷管接头冷弯件,采用数值模拟方法分别研究了芯棒伸出量e、防皱块与管坯间隙c以及芯棒直径d等工艺参数对冷弯成形质量的影响.结果表明:随着芯棒伸出量e增大,管坯外侧壁厚减薄率γ增大,管坯内侧起皱趋势先减小再增大；随着管坯与防皱块的间隙...

| Abstract: | Inner wall wrinkle and outer wall thinning are the main defects occurred during thin-walled tube rotary bending.The influence of different processing parameters,such as the mandrel extension length e,the clearance between wiper die and tube c,and the mandrel diameter d on the forming quality were analyzed based on numerical simulation method to avoid the defects during tube rotary bending of automotive water-cooled tube.The results show that the larger the mandrel extension length e,the greater the thicknes... |
