通常高盒形件多次拉深时,变形区内的变形沿周边的分布很不均匀,因此往往出现变形区圆角部分的横向堆聚和底部断裂现象。本文通过对高盒形件拉深时的变形分析提出了均匀变形的条件及中间工序合理过渡形状,并在此基础上给出了合理壁间距离公式及毛坯尺寸的确定方法。 Generally, the deformation of the deformation in the deformation zone is unevenly distributed along the periphery when the box-shaped member is frequently drawn several times. Therefore, the transverse accumulation and the bottom fracture of the corner portion of the deformation zone tend to occur. In this paper, the conditions of uniform deformation and the reasonable transitional shape of the intermediate process are proposed by analyzing the deformation of the high-box parts. Based on the above analysis, the formulas of reasonable distance between walls and the determination of the size of the blank are given.
