ABSTRACT:
Apparatus for forming cup-shaped metal containers from a metal blank by drawing and then redrawing the blank to its finished configuration is disclosed. The apparatus is intended for use in a double acting press having inner and outer rams which operate in relatively timed relationship. The means for performing the drawing operation are operatively associated with the outer ram and the means for performing the redrawing operation are carried by the inner ram. The drawing means are pneumatically activated and the redrawing means on the inner ram are telescopically received within the drawing means of the outer ram and carry peripheral radially extending shoulders thereon for engagement with the drawing means so that, for at least a portion of the travel of the inner ram, travel of the drawing means is retarded thereby controlling the timing of the actuation of the drawing means and reducing the stroke of the press required to accomplish the triple action drawing and redrawing function.
