Abstract

PURPOSE: To draw into sufficient depth without redicing the thickness between plural draw forming parts, by placing a blank on the surface of a plurality of dies set in parallel arrangement, and moving necessary dies laterally while drawing by lowering the punch into each die.
CONSTITUTION: A blank 24 is placed on dies 12A, 12B which are seperated to the maximum spacing by means of springs 13A, 13B, and the blank 24 is held by holders 18A, 18B by means of springs 20A, 20B. Punches 21A, 21B are separated to the maximum spacing by means of the both holders and sheet bodies 19A, 19B, and are made to correspond to pressure chambers 15A, 15B respectively through the blank 24. In this state, an elevating body 22 is lowered, and the both punches are lowered to draw deeply. When drawing, the both dies resist the springs 13A, 13B and approach to each other, and the both punches also approach each other consequently. By this lateral motion, reduction of thickness of blank 24 between the both dies is prevented, and drawing operation ends when the both dies contact with each other.
