| Abstract: | On analysis of the forming of drawbead during the drawing of parts with bead,the formula for forming force of the drawbead has been deduced,and is checked by experiment. At the same time,the formula for the minimum blank holder force has also been derived which ensures that the blank bolder will not be lifted during the drawing of parts. |
