| 摘 要： | 作为非回转对称成形试验研究的一部分,进行了大量的矩形盒拉深试验。指出纯铜薄板的各向异性对矩形盒拉深成形性的影响不十分显著。增大凸模形状参数rc/w,成形中法兰短边和曲边材料向凹模口的流入速度减小,曲边变形加工度增大,是使成形极限降低的原因之一。rc/w=0.1附近,极限成形高度hmax最大。

| Abstract: | A lot of experiments of rectangular case drawing are perfomed as a part of strudies of non-rotative symmetrical drawing forming experiments.It's pointed out that the effect of the anisotropy of fine copper on the drawing forming property of rectangular case isn't remarkable.Increasing punch shape parameter r_c/w results in the decrease of the velocity of material of flange short side and corner flowing into die edge,thus enhancing the forming machining degree of corner.It's one of the reasons that the forming limit is decreased.The maximal forming height is achieved when r_c/w is close to 0.1. |

| Keywords: | rectangular case flange straight sides and corner side deformation work |
