    摘要:

    为了解决0Cr17Ni7Al弹簧钢丝在拉拔过程中出现的残余应力问题及钢丝卷曲后的回弹现象,通过实验观测和有限元模拟相结合的方法,分析了拉拔工艺参数对残余应力及钢丝翘距的影响,并构建了残余应力与翘距之间的量化关系模型。结果表明:卷丝过程中丝圈轴向的塑性变形是翘距产生的主要原因,而残余应力的分布特征对翘距有显著影响;通过调整拉拔参数可以有效控制翘距;翘距与残余应力之间的关系模型准确度高达0.97。研究结果深化了对拉拔工艺中残余应力影响的理解,为钢丝的后续加工和应用提供了技术参考。

    Abstract:

    In order to solve the problem of residual stresses in the drawing process of 0Cr17Ni7Al spring steel wire and the rebound phenomenon after the wire curling, the effects of drawing process parameters on residual stresses and wire warpage were analyzed through a combination of experimental observation and finite element simulation. Subsequently, a quantitative relationship model between the residual stresses and warpage was constructed. The results indicate that the axial plastic deformation of the wire coil during the winding process is the primary cause of warpage, and the distribution characteristics of the residual stress have a pronounced impact on warpage. By adjusting the drawing parameters, the warpage can be effectively controlled. The accuracy of the relationship model between warpage and residual stress is as high as 0.97. The research result deepens the understanding of the influence of residual stress in the drawing process, and provides technical reference for the subsequent processing and application of the steel wire.
