Definitions

  • This disclosure relates to a tool pack for use in manufacturing metal containers, and in particular, to a tool pack that includes a redraw die and two ironing dies for consistently forming tall, aluminum cups for use in producing bottle-shaped containers at high production speeds.
  • Thin-walled, two-piece metal cans are often produced using drawing and ironing processes.
  • a drawing and ironing process a flat circular blank of metal is drawn through one or more drawing dies to form a shallow preform cup.
  • the preform cup is then mounted on a free end of a punch which extends from a reciprocating ram.
  • the preform cup is then passed through one or more redraw dies and is then “ironed” by passing through one or more ironing dies to lengthen and thin the sidewall of the cup to form a formed cup.
  • ironing refers to the operation of forcing the cup through an ironing die by means of the punch resulting in a reduction of the sidewall thickness of the cup and an elongation in the height of the cup.
  • a liquid is placed in the cup and a lid is clamped onto the formed cup to complete the formation of the two-piece metal can.
  • drawing and ironing machines produce cans at a high rate, for example, 400 cans per minute.

  • tool pack designs used to form metal cans include at least one redraw die and three ironing dies in a 30-inch stroke bodymaker. It has been found, however, that such “three-iron” tool packs do not consistently produce tall, thin-walled cups for use in forming tall, thin-walled bottle-shaped containers at high production speeds. By restricting the number of dies, and, specifically, by incorporating only 2 ironing dies 104 and 106 into a 30-inch bodymaker 100 , it has been found that defect rates in the production of tall, thin-walled, bottle-shaped containers can be reduced and that the amount of work performed on the cup can be controlled to more consistently produce acceptable cups for use in forming tall, thin-walled, bottle-shaped metal containers.
  • the above-described distances between the redraw die 102 , the first ironing die 104 and the second ironing die 106 provide for a tool pack 200 that can be contained within a 30 inch stroke bodymaker 100 to consistently produce a tall, aluminum, bottle-shaped containers at high production speeds.

It is expected that higher production speeds and thinner sidewall thicknesses will be possible in the future. For example, it is expected that the tool pack will be able to consistently produce a cup that has a total height of about 9.4 inches and a sidewall thickness of less than about 0.0083 inches at high production speeds of between about 250 and about 280 bottles per minute or higher.

  • An inner coating 430 may be applied to an inner surface of the elongated bottle 400 for separating a beverage from the metal of the bottle 400 .
  • the cylindrical portion 410 of the bottle 400 has a height of between about 6.2 inches and about 6.4 inches. In other embodiments, the cylindrical portion 410 has a height of about 6.38 inches. In some embodiments, the bottle 400 has an overall height of between about 7.4 inches and about 9.4 inches. In other embodiments, the bottle has an overall height of about 9.37 inches.
  • the above-described bottle 400 can be produced with increased consistency and with a lower defect rate using the tool pack 200 than with traditional 3 -iron tool packs that include three ironing dies in a 30-inch stroke bodymaker.
  • the tool pack 200 allows for the creation of a bottle with an overall height of about 9.37 inches while avoiding contact between the cup and more than one die 102 , 104 or 106 at a time during production to thereby lower the risk of tearing the cup material. It has also been found that the tool pack 200 allows for an appropriate amount of work hardening to the cup to allow the cup to be necked, threaded and flanged with low instances of cracking or tearing during these operations.
  • FIG. 5 illustrates an embodiment of a method 500 of creating a metal bottle using the tool pack 200 of FIG. 2 .
  • the method 500 is performed on a bodymaker 100 that has about a 30-inch stroke.
  • the method 500 begins and a redraw die 102 , a first ironing die 104 and a second ironing die 106 are provided, as shown at block 502 .
  • the contact portion 208 of the redraw die 102 is spaced by a distance 214 that is about 4.4924 inches from the contact portion 210 of the first ironing die 104 .
  • the contact portion 210 of the first ironing die 104 is spaced by a distance 216 that is about 6.6265 inches from the contact portion 212 of the second ironing die 106 .
  • the redraw die 102 , a first ironing die 104 and a second ironing die 106 fit within a 30-inch stoke bodymaker.
  • the distances between the redraw die 102 , the first ironing die 104 and the second ironing die 106 allow for the consistent creation of a tall cups that can be formed into bottle-shaped containers 400 with a total height of about 9.4 inches or more.
  • a cup is then forced by a plunger through the redraw die 102 to lengthen the walls of a cup, to decrease the wall thickness of the cup and to decrease the diameter of the cup, as shown at block 504 .
  • the plunger then forces the cup through the first ironing die 104 , as shown at block 506 , and the first ironing die 104 reduces the sidewall thickness of the cup by between about 10 and about 40 percent.
  • the cup is then forced through the second ironing die 106 , as shown at block 508 , and the second ironing die 106 reduces the sidewall thickness of the cup by between about 35 and about 44 percent. In some embodiments, the second ironing die reduces the sidewall thickness of the cup by between about 38 and about 42 percent.
  • the second ironing die reduces the sidewall thickness of the cup by between about 39 and about 41 percent. In yet other embodiments, the second ironing die reduces the sidewall thickness of the cup by about 40 percent. Additional forming processes, such as necking to form a necked portion of the bottle, may be performed to create a bottle that has a height to width ratio of about 4, as shown at block 510 .
