通过实验测试了焊接毛坯冲压成形 (弯曲、拉深 )过程中产生的残余应力 ,并对实验结果进行了分析。通过分析得出了对焊接冲压成形加工复合化技术工艺实践有指导意义的结论。 The residual stress produced during stamping (bending and drawing) of the blank is tested by experiments and the experimental results are analyzed. Through the analysis, it is concluded that the composite technology of the stamping forming process has guiding significance.
