Abstract

PURPOSE: To effectively utilize a frictional holding effect at the central wall part to deeply draw a sink, by forcing a working oil under pressure into a space between a blank holder and a blank while exhausting said oil from the bottom of a punch.
CONSTITUTION: A blank 7 is mounted on a die 1 and clamped with a blank holder 6. When a working oil under pressure is forced into a space between the blank holder 6 and the blank 7 from the bottom of punches 5a, 5b to add a hydraulic pressure, the drawing of the flange part of blank 7 begins while expanding the blank 7. The punches 5a, 5b are forced into the die with a prescribed force F1 against a prescribed force F2 of blank supporting plates 14a, 14b while increasing the hydraulic pressure P1. When the pressure P1 reaches a prescribed pressure, the working oil between the punch bottom and the blank 7 is exhausted through escaping paths 11a, 11b and a relief valve 9. When the forming is advanced, feeding of the working oil is stopped, and the forming is completed after lowering the punches 5a, 5b to a prescribed position.
