| 中文摘要: |
| 管子组件加工过程中经常出现漏气和扩口裂纹问题， 为了解决此类问题， 对不锈钢细管扩口工艺进行研究， 通过管端壁厚计算、 扩口力的计算及扩口应力的理论分析， 为管子组件扩口工艺提供理论依据； 有效避免了管子组件压力试验漏气及零件扩口裂纹问题， 不锈钢管材供应状态及平管嘴口部转角对管子组件的成形影响较大。 |
| 英文摘要: |
| Tube component leakage and flaring crack often appear in the manufacturing process. In order to solve such problems， in this paper， the flaring process of stainless steel tube was studied. Through the pipe wall thickness calculation， the calculation of the force of flaring and the analysis of the flaring stress theory， this paper provided theoretical basis for flaring tube component technology. These theories in this paper effectively avoided the air leakage of pipe components in the pressure experiment and the flaring crack of parts， the final conclusion showed that stainless steel pipe supply condition and flat nozzle mouth corner r had a great influence on the forming of pipe components. |
