Abstract
Through analysis of the structure characteristics and stamping technology of the rectangular parts with thin deep cylinder, the drawing progressive die is designed. Key problems such as the deep rectangular forming, wrinkles in the small fillet area and crack are solved. The process involving transition from the circular tube to an oval tube and then the transition from oval to rectangular tube is applied. Using the combination of drawing and extrusion methods, reasonable choice of workpiece materials and drawing coefficient, and the problem is solved. Product quality is stable and the die is endurable.关键词
