| Abstract: | By the equal area assumptions before and after metal plastic deformation, two traditional formulas are derived a-bout a tapered necking blank calculation from the geometrical and mathematical considerations. Two new calculation formulas of cone type necking blank are established by contrastive calculation of the practical example and analysis and comprehensive in-duction based on the constancy of volume in the principle of metal plastic forming. |

| Keywords: | cone type necking blank equal area constancy of volume thickness coefficient |
