本文对无模拉伸成形时的高频感应加热和喷气冷却过程进行了分析,研究了其工艺参数与拉伸温度场和拉伸力的关系。研究结果表明,随着加热和冷却装置移动速度的提、加热线圈与冷却喷嘴间距的减小,拉伸温度下降,拉伸力增大;变形程度对拉伸温度影响小,变形程度的增大使拉伸力下降。 In this paper, the process of high-frequency induction heating and jet cooling during die-less stretch forming was analyzed, and the relationship between process parameters and drawing temperature field and drawing force was studied. The results show that as the moving speed of the heating and cooling device is raised and the distance between the heating coil and the cooling nozzle is reduced, the stretching temperature is decreased and the stretching force is increased. The effect of the deformation degree on the stretching temperature is small and the degree of deformation is increased Tensile force decreased.
