Abstract
A press of improved moldability and operation efficiency, including an upper movable die having a concave bottom surface, a lower, stationary arc having a convex top surface conforming to the concave bottom surface of the upper die, a blank holder arranged around the lower die for vertical sliding movement, and a blank support lever arm pivotally mounted on top of the blank holder. The blank holder is normally held raised by cushion means in such a position that its top surface is lower than the crest of the convex top surface of the lower die. The blank support lever arm is normally biased to a horizontal position to support a blank in a horizontal position in co-operation with the crest of the lower die and is tilted down by the upper die in downstroke movement out of its path, allowing the blank to be pressed down.
