Die-set Development of Multi-action Forward Extrusion for Hole-flanging
碩士 === 南台科技大學 === 機械工程系 === 93 === Wall thickness and flange height are restricted by the formation limit of metal blank during hole flanging operation. Wall thickness decreases and necking and/or fracture occur before the flange reaches the desired height in the process of drawing, and consequently...
