摘要
通过对曲面零件带筋拉深中筋的成形过程的分析 ,推导了拉深筋的成形力公式 ,并且进行了试验验证 .同时 。
On analysis of the forming of drawbead during the drawing of parts with bead,the formula for forming force of the drawbead has been deduced,and is checked by experiment.At the same time,the formula for the minimum blank holder force has also been derived which ensures that the blank holder will not be lifted during the drawing of parts.
