The invention relates to a method for bi-directionally drawing flexible matter in plane, belonging to the experiment technique. It comprises following steps: (1) selecting drawing mold plate: the drawing mold plate is a round smooth stainless steel sheet with the thickness of 0.5-5mm and the diameter of 40-300mm; (2) cutting said drawing mold plate into 4 same parts: drawing a round on the center of drawing mold plate, and using vertical theory of plane geometry to confirm the quarter points of drawing mold plate and the round drawn on the flexible matter; (3) bi-directionally drawing the flexible matter in plane: first matching the quarter points of said drawn round and the drawing mold plate, then drawing flexible matter to match its round and the edge of drawing mold plate; (4) retracting drawn flexible matter: attaining the drawn flexible matter on the drawing mold plate, it will automatically retract to initial natural condition. The invention can realize uniform bi-directional drawing of flexible matter and controllably recover the flexible matter to natural condition. |
