摘要

对不锈钢薄壁管件在成形过程中的壁厚分布进行了研究。对某客车用接头的弯曲和液压成形过程进行了仿真和实验分析。目的是分析工艺参数对壁厚分布的影响。利用Auto Form软件对弯曲过程进行模拟,研究相对弯曲半径(管件弯曲中性层的相对弯曲半径与管径之比)对壁厚分布的影响。随后,在不同的内压加载条件下进行了液压成形模拟。结果表明:随着相对弯曲半径的增大,管件的最大减薄速率和最大增厚速率均逐渐减小;根据仿真结果,确定了最优弯曲工艺参数为初始管径为62 mm,弯曲半径为95 mm。通过液压成形有限元模拟,对比了30 MPa、40 MPa和50 MPa的内压力,确定了40 MPa为最优成形压力。根据仿真得到的最优参数进行了薄壁管件的加工,并通过实验验证了优化参数的正确性。实验结果与仿真结果吻合较好,最大误差为2.27%。最终成形的零件符合各项要求,无任何故障。

Bending-hydraulic forming stainless steel thin-walled tube fittings wall thickness distribution law research
A study was conducted to examine the distribution of wall thickness in stainless steel thin-walled tube fittings during the forming process. The research included simulation and experimental analyses of the bending and hydroforming processes of these fittings used in a passenger car. The goal was to analyze how process parameters affect the distribution of wall thickness. Auto Form software was utilized to simulate the bending process and investigate the impact of relative bending radius (Relative bending radius for the tube fittings bending neutral layer of the ratio of the radius and diameter of the tube) on the wall thickness distribution. Subsequently, hydroforming simulations were performed under varying internal pressure loading conditions. The findings revealed that as the relative bending radius increased, both the maximum thinning rate and maximum thickening rate of the tube fittings gradually decreased. Based on the simulation outcomes, the optimal bending process parameters were determined to be a 62 mm initial tube diameter and a 95 mm bending radius. Through finite element simulations of hydroforming, internal pressures of 30 MPa, 40 MPa, and 50 MPa were compared, with 40 MPa identified as the optimal pressure for forming. The thin-walled tube fittings were then manufactured based on the optimal parameters obtained from the simulation, which were validated through experimentation. The experimental results closely matched the simulation results, with a maximum error margin of 2.27 %. The final formed parts met all requirements without any failures.
