  • Patent number: 4080819
    Abstract: Press mounted apparatus is disclosed for shearing a blank from a metal sheet and for drawing the blank to a cup-shaped configuration. The apparatus includes a fixed annular drawing die mounted on the press bed and having a drawing surface extending radially from the die opening and terminating in a circular cutting edge, and a movable tool assembly mounted on the press slide and including a draw pad and a cutter member. The draw pad is mounted on the slide for reciprocating movement relative thereto and to the cutter member. The cutter member is cooperable with the cutting edge on the fixed die to sever a blank from a sheet of material therebetween, and the draw pad has a drawing surface opposite the drawing surface of the fixed die. The two drawing surfaces engage opposite sides of the blank, and the drawing surfaces are spaced apart a predetermined distance related to the thickness of the sheet material by opposed pins carried respectively by the draw pad and fixed tool assembly.
