| 摘 要： | 通过石油井下钻具接头螺纹冷滚压工艺的研究可以证明冷滚压可大大地提高接头的疲劳强度.我们经一年的研究,找出了滚压力与残余应力的关系曲线,进而推得冷滚压的最佳参量,其结果与美国 CHRISTENSEN 公司和 SMITH 公司的研究结论基本一致.

| Abstract: | This article proves that rolling operation can largely enhance fatigue strength through the research on the cold rolling operation of thread root of the drilling tool joint.The key to the use of this operation lies in finding the best rolling pressure.We hare found a pressure-remanent stress relation curve and worked out the best rolling,pressure by thls curve after one year,s research.The result is almost the same with that of the CHRISTENSEN corp and the SMITH Corp of the United States. |
