摘要
分析了拉伸过程中压边力的变化规律,改进了弹性压边装置的结构,实现了弹性压边拉伸过程中压边力的恒定,并能调整压边力的大小,对中小型零件的拉伸过程有较好的改善。
The changing rules of blank holder pressure during the drawing were analyzed. The structure of the elastic blank holding device was improved. With that, the blank holder pressure was kept constant during the whole period of elastic blank holding drawing, and the value of the blank holder pressure could be adjusted.
