A press drawing method includes a first step for moving an upper mold 10e from a top dead center to a fracture position and applying a predetermined strain to a part of a plate material 1 to be drawn, causing the plate material 1 to fracture at a fracture part 4, and a second step for moving the upper mold 10e from the fracture position to a bottom dead center, thus completing the drawing process. |
