摘要: 非API螺纹量规的成形磨削加工质量直接影响了油气井长期服役的安全性能,螺旋齿形结构,IT3~IT4级尺寸精度,其在极端服役环境下的抗疲劳性能与材料热处理状态和量规磨削加工质量密切相关。然而,螺纹量规材料磨削烧伤与磨削裂纹已成为制约量规高效成形磨削的瓶颈问题,严重降低了量规的耐磨损性能和使用寿命。为此,提出了基于量规的使役性能需求,来驱动量规材料的热处理和磨削参数优化,通过开展定量描述量规材料热处理与磨削加工性能之间的关系,来解决量规材料的磨削烧伤和磨削裂纹问题。结合热处理和平面磨削试验,结果显示优化的热处理工艺能够有效提升量规材料的磨削加工质量,同时也表明良好的热处理工艺和磨削加工参数相结合,是控制非API螺纹量规材料磨削性能的重要保障。

Abstract: Safety production of oil-gas well is directly affected by the forming grinding quality of non-API thread gauge. Spiral tooth, up to IT3~IT4 level of dimensional accuracy, fatigue resistance performance (up to 20 000 cycle time) under severe service condition, all of these requirements have close relation with the heat treatment and grinding processes which used in the machining of thread gauge. However, in the final grinding of thread gauge, surface defects on tooth such as grinding burn on the flange, grinding crack are often happened. These defects would significantly reduce the abrasion resistance and service life of the gauge. In order to solve this situation, based on favorable usability and service properties of the gauge, this topic proposed a method to optimize the heat treatment of die steel which is the workpiece material and grinding parameters in parallel. Studies involve quantitative description of the relationship between heat treatment of die steel and its grinding performance, the grinding burn and crack could be solved by this technique. Heat treatment and surface grinding experiments are carried out on die steel, the results show that the optimized heat treatment improves the grinding quality of the material effectively. It also indicated the combination of optimized heat treatment and grinding parameters was the necessary condition in grinding of gauge material.
