Abstract: Can shells are produced with tooling installed on a single action mechanical press, and the tooling includes an upper retainer supporting a blank and draw die enclosing an outer pressure sleeve and an inner pressure sleeve surrounding a die center punch, all having air actuated pistons. The die center piston has an air reservoir connected by air passages which form air springs for the inner pressure sleeve, and the outer pressure sleeve receives the same controllable air as the reservoir or low pressure plant air supply. The inner pressure sleeve has a projecting nose portion which initiates the drawing of a cup and has contoured surfaces which mate with corresponding surfaces on a die core ring to form and clamp the chuckwall of the shell during downstroke of the press. A lower panel punch forms the center panel, panel wall and countersink of the shell during upstroke of the press.

Abstract: Can shells are produced with tooling installed on a mechanical press, and the tooling includes an upper retainer supporting a blank and draw die enclosing an outer pressure sleeve and an inner pressure sleeve surrounding a die center punch, all having pistons. An air chamber is connected by air spring passages to the inner pressure sleeve piston, and the outer pressure sleeve receives the same air as the air chamber or lower pressure air. The die center punch has an insert which initiates the drawing of a cup, and the inner pressure sleeve and die center punch have contoured surfaces which mate with opposing surfaces on a die core ring to form and clamp the chuckwall of the shell during downstroke of the press. A panel punch has peripheral surfaces which form the panel wall and countersink of the shell during upstroke of the press.

Abstract: A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by an inclined curved or straight panel wall to an inclined inner wall of an annular U-shaped countersink. The countersink has an outer wall which connects with an inclined lower wall portion of a chuckwall at a junction below the center panel, and the chuckwall has a curved or inclined upper wall portion which connects with an inner wall of the crown. The chuckwall also has an intermediate wall portion forming a break, and the inner bottom width of the countersink is less than the radial width of the panel wall. The inclined upper wall portion of the chuckwall extends at an angle greater than the angle of the inclined lower wall portion of the chuckwall.

Abstract: A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by a curved panel wall to an inner wall of an annular U-shaped countersink. The countersink has a generally cylindrical outer wall and an inner width less than the radius of the panel wall. The outer wall of the countersink connects with a frusto-conical chuckwall at a junction below the center panel, and the chuckwall extends to an inner wall of the crown at an angle of at least 160 with the center axis. In one embodiment, the chuckwall has an intermediate generally vertical riser portion with small radii, the inner bottom width of the countersink is less than 0.040 inch, and the inner wall of the countersink extends at an angle greater than 10°.
