根据某V型支撑板翻边件的几何特点,制定了对称双件翻边的成形方案,并利用数值模拟手段对方案进行了评估。发现局部翻边区域由于板料伸长率过大,容易出现破裂现象,同时底部区域因为成形中不均匀拉力的作用发生材料聚集,最后引起受压失稳而起皱,结论得到了试验结果的验证。结合数值模拟,提出了零件工艺性的改善措施,获得了合格的零件。 According to the geometrical characteristics of a V-shaped support flange, the forming scheme of the symmetric double flange was established and the scheme was evaluated by numerical simulation. It is found that the local flanging area is prone to rupture due to the excessive elongation of the sheet material, and the material aggregation occurs in the bottom area due to the non-uniform tensile force during forming, which eventually leads to buckling under pressure and buckling. verification. Combined with the numerical simulation, the improvement measures of the parts’ craftsmanship are proposed and the qualified parts are obtained.
