Temperature control mechanism for use in the manufacturing of metal containers

1. A cooling assembly adapted for use with an apparatus for altering the shape of a metallic container, comprising:

a frame;

a turret supported by said frame, said turret comprising a plurality of mandrels, each of said mandrels adapted for retaining at least one metallic container;

a chamber substantially enclosing said turret;

a cooling system, wherein an intake air temperature entering said cooling system is greater than a discharge air temperature exiting a discharge port of said cooling system;

a conduit operably interconnecting said discharge port of said cooling system to an inlet in said chamber such that air discharged from said cooling system is directed into said chamber;

a first opened shroud, which possesses a generally c-shaped cross section in operable communication with said inlet of said chamber, said first opened shroud shaped to direct cooled air from said cooling system around a portion of the circumference of said turret that is adjacent to said first opened shroud;

a second opened shroud, which possesses a generally c-shaped cross section in operable communication with said inlet of said chamber and spaced from said first opened shroud, said second opened shroud shaped to direct cooled air from said cooling system around a portion of the circumference of said turret that is adjacent to said second opened shroud; and

wherein the discharged air is operably divided and directed to said first opened shroud and said second opened shroud and directed generally around the circumference of said turret, wherein the temperature of the turret and said mandrels can be maintained within a pre-determined range.

2. The cooling assembly of claim 1 , wherein said first opened shroud and said second opened shroud have arcuate-shaped portions.

3. The cooling assembly of claim 1 , wherein said first opened and said second opened shroud have at least one portion with a radius of curvature which is proximate to the radius of curvature of the circumference of the turret.

4. The cooling assembly of claim 1 , wherein said cooling system regulates the temperature of the mandrel within a range of about 0.5-3.0 degrees Fahrenheit.

5. The cooling assembly of claim 1 , wherein said first opened shroud and said second opened shroud are comprised of at least one of a metallic material, a ceramic material, and a fiberglass material.

6. The cooling assembly of claim 1 , wherein said cooling system further comprises a damper and a modulating motor, wherein ambient air can be commingled with the cooled discharge air prior to introduction into said chamber inlet.

7. The cooling assembly of claim 1 , wherein the apparatus is a beader used in a metallic container manufacturing plant to selectively alter the geometry of the metallic container in a predetermined location.

8. A cooling assembly adapted for controlling an air temperature in a metallic container beader comprising a frame, a turret supported by the frame and a chamber substantially enclosing the turret, comprising:

a cooling assembly with an air inlet port and an air outlet port, wherein the temperature of air discharged from said outlet port is less than the temperature of air entering the inlet port;

a conduit interconnected on a first end to said outlet port and a second end to an inlet of said chamber such that air discharged from said cooling assembly is directed into said chamber;

a first opened shroud, which possesses a generally c-shaped cross section in operable communication with said inlet of said chamber, said first opened shroud shaped to direct cooled air from said cooling system around a portion of the circumference of said turret that is adjacent to said first opened shroud;

a second opened shroud, which possesses a generally c-shaped cross section in operable communication with said inlet of said chamber and spaced from said first opened shroud, said second opened shroud shaped to direct cooled air from said cooling system around a portion of the circumference of said turret that is adjacent to said second opened shroud; and

wherein the discharged air is divided and directed to said first opened shroud and said second opened shroud and substantially directed around the circumference of said turret.

9. The apparatus of claim 8 , wherein said first opened shroud and said second opened shroud have an arcuate shape.

10. The apparatus of claim 8 , wherein said turret further comprises a plurality of mandrels which are adapted to receive a metallic container.

11. The apparatus of claim 8 , wherein said first opened shroud and said second opened shroud substantially direct air flow around a circumferential exterior surface of the turret.

12. The apparatus of claim 8 , wherein at least one of an air temperature and rate of flow of cooled air entering the chamber is selectively controlled based on the speed of operation of the turret.

13. The apparatus of claim 8 , wherein said first opened shroud and said second opened shroud is comprised of a metallic material.

14. A method for controlling the temperature of a beader used to alter the geometry of a metallic container, comprising:

providing an apparatus having a frame, a cylindrical shaped turret rotatably interconnected to said frame, and a chamber substantially enclosing at least said turret;

providing a plurality ofmandrels operably interconnected to said turret, each of the mandrels adapted to hold at least one container;

providing an open cooling mechanism operably interconnected to at least one entry port of said chamber, said cooling mechanism adapted to reduce the temperature of ambient air; and

controlling the direction of cooled air within said chamber, wherein the cooled air is directed around a perimeter surface of the turret to control the temperature of the turret and plurality of mandrels while the geometry of the metallic container is altered, said controlling comprising directing air around a first portion of the circumference of said turret that is adjacent to a first opened shroud and directing cooled air from said cooling system around a second portion of the circumference of said turret, wherein the temperature of the turret and said mandrels can be maintained within a pre-determined range.

15. The method of claim 14 , wherein the turret operating temperature is maintained within a range no greater than about 2° F.

16. The method of claim 14 , wherein controlling the direction of cooled air comprises employing at least one shroud with an arcuate shape.
