摘　　要：针对提升斜轧丝杠产品精度的需求,通过研究斜轧丝杠成形原理,在工厂之前使用的依靠经验和通过大量试轧丝杠并根据其试验检测得到的精度来确定轧制成形过程中相关参数方法的基础上,通过DEFORM-3D软件对轧制成形过程的有限元仿真,利用仿真总结出各参数对轧制丝杠的影响规律,在经过试验验证规律的正确性后,计算出了优化后的斜轧丝杠工艺参数,生产对应参数的轧制丝杠以验证精度的提升。该优化方法使用的轧制实验件少、过程简单成本较低,考虑到各生产环节对丝杠精度的影响,充分联系实际生产,获得的优化结果可靠性高,且该方法适用范围较广。工厂利用优化的后斜轧丝杠工艺参数生产后,斜轧丝杠的精度获得了明显提升,最高达P4级精度。In response to the demand for improving the accuracy of oblique rolling screw products,by studying the forming principle of oblique rolling screw,based on the previous experience used in the factory and the method of determining the relevant parameters in the rolling forming process through a large number of trial rolling screws and their accuracy detected through experiments,the finite element simulation of the rolling forming process was carried out using DEFORM-3D software,and the influence of each parameter on the rolling screw was summarized through simulation,After verifying the correctness of the rules through experiments,the optimized oblique rolling screw process parameters were calculated,and corresponding rolling screws were produced to verify the improvement in accuracy.This optimization method uses fewer rolling experimental pieces,has a simple process and lower cost.Considering the impact of each production link on the accuracy of the lead screw,and fully connecting with actual production,the obtained optimization results are highly reliable,and this method has a wide range of applications.The factory has significantly improved the accuracy of the oblique rolling screw by utilizing optimized process parameters,with a maximum accuracy of P4 level.
