Abstract
A split punch tool for cooperating with a die block to form the wall of a drawn and ironed container is disclosed herein. The split punch or cooperating die includes a female portion that has a peripheral lip that can be placed in overhanging relation to the periphery of the die block and the female portion has a peripheral ledge which extends perpendicular to the direction of movement of the die block and die with respect to each other and also an inclined surface extending from the inner edge of the ledge or inwardly directed surface. The surfaces are adapted to engage mating surfaces defined on the end of a cylindrical member that forms part of the cooperating die so that the ledge defines a perpendicular support for the cylindrical member.
