摘　　要：提出了一种机械式的变压边力拉伸模结构 ,其压边力由弹簧或橡胶提供。在冲压拉伸过程中压边力可以随拉伸行程合理变化 ,能较好地满足拉伸工艺的要求。The author proposed a kind of mechanical drawing mould structure of varied edge-pressing force. The edge_pressing force was provided by spring or rubber. During the stamping and drawing, the edge_pressing force varied reasonably with the drawing stroke, well meeting the requirement of drawing technology.
