本文利用激光诱导热成形技术对5A06铝合金交叉筋壁板进行圆柱面弯曲成型的过程中,根据交叉筋分布位置,对边缘区、筋部及网格区扫描时壁板的多道扫描变形进行实验研究,讨论扫描方式对壁板成形的影响。针对多道扫描过程中非期望变形的累积效应,提出一种扫描纵向加强筋的方法来减小自由端的纵向弯曲程度,并对交叉筋壁板圆柱面弯曲成型的多道扫描流程和扫描策略进行规划,通过成形试验检验策略的有效性。
In this paper, laser-induced thermoforming technology 5A60 aluminum alloy cross-ribbed wall cylinder bending process, according to the distribution of cross-rib, the edge of the area, the Department of grid and grid scanning multi-channel scanning of the wall deformation Experimental study to discuss the impact of scanning mode on the forming of siding. Aiming at the cumulative effect of undesired deformation during multi-pass scanning, a method of scanning longitudinal stiffeners was proposed to reduce the longitudinal bending of free ends. The multi-pass scanning process and scanning strategy of cylindrical curved forming of cross rib panels Planning, test the effectiveness of the strategy through the forming test.
