Abstract:
1. A tooling assembly for forming a shell having a preselected depth, the tooling assembly comprising: a die center; a panel punch located in opposed relation to the die center; a panel punch piston coupled to the panel punch, the panel punch piston having an upper end; and a spacer member disposed concentrically around an outside surface of the panel punch piston at or proximate to the upper end of the panel punch piston, wherein an upper end of the spacer member is in contact with a lower end of the panel punch and the spacer member is located proximate to a peripheral surface of the lower end of the panel punch, wherein the tooling assembly is movable between a first position in which a lower end of the spacer member is structured to be spaced apart from an opposing portion of the tooling assembly, and a second position in which the lower end of the spacer member is structured to engage the opposing portion of the tooling assembly, thereby establishing the preselected depth of the shell, and wherein the second position in which the preselected depth of the shell is established corresponds to a bottom of a stroke of the tooling assembly.
