Definitions

  • the cups are then conveyed to a second press or "bodymaker” where they undergo at least a second stamping and several successive draws; these consist of passing the stamped blank by stretching rings in order to lengthen the metal and thin it.
  • Boxes whose walls are thinner than the bottom are thus progressively obtained. These boxes are then processed in a machine that prints a rotary motion while a shear cuts at the desired height.
  • the beverage cans are then conveyed to a necking and edging station (or edging) also known as a “necker flanger" where the upper part of the preform undergoes several successive diameter narrowing and a border for the subsequent installation of the lid.
  • a necking and edging station also known as a “necker flanger” where the upper part of the preform undergoes several successive diameter narrowing and a border for the subsequent installation of the lid.
  • Metal cylinders and aerosol cans or aerosol cans, made of aluminum alloy, are traditionally made by shock spinning, from pawns from wheel casting.
  • bottles are however not monobloc structure. Indeed, the vertical walls and neck of the bottle are made from the bottom of the preform and a cover is crimped on the top of the preform. So is it also in the case of the application WO 01 15829, Daiwa Can in 2000 under priority of 1999, which claims an aluminum alloy bottle manufactured by hot forming with complex tooling.
  • the design and use in production of non-circular blanks for the manufacture of beverage cans are part of the state of the art.
  • the objective is to compensate for the anisotropy of the metal by varying the diameter of the blank according to its orientation with respect to the rolling direction.
  • This technology is advantageous because it increases the ratio between the amount of metal actually used in the beverage can and the amount of metal engaged on the flat metal, or strip.
  • the profile of the cup always has hollows and horns at the expense of the ratio between the amount of metal actually used in the beverage can and the amount of initial metal on the flat metal.
  • the invention aims to solve these difficulties by providing a non-circular blank eliminating any risk of horn (s) pinch (s) during the stamping cups or "cups".
  • the subject of the invention is a method for manufacturing a beverage can, a bottle or an aluminum alloy aerosol can, by drawing-drawing followed by shrinking and / or folding, starting from a blank circular, according to which:
  • the perimeter of said blank is calculated by adjusting from a concentric circle and radius less than that of the inscribed circle of the corresponding hexagon, to compensate, during stamping, the anisotropy of the behavior of the metal, according to a method known to those skilled in the art, typically as described in the article "Convolute Cut-Edge Design for an Earless Cup in Cup Drawing” by Dick RE, JW Yoon and F. Barlat, CP778 Volume A, Numishet 2005
  • At least four horns are added beyond and from said perimeter, in the zones of the hexagon left free, or the main axis of which forms an angle of approximately 35 °, 145 °, 215 ° and 325 ° respectively with the rolling direction, each of a relative height of 0.3 to 0.8% relative to said concentric circle of departure, and a maximum width in view of the available space, is typically corresponding, halfway up the said horn , at a minimum angular sector of substantially 25 ° having at the top the center of the blank.
  • the invention also relates to a beverage can draw blank, metal bottle or aerosol can manufactured by a method as described above.
  • a drink-box or metal bottle still known to those skilled in the art under the repetitive designations of "can” or “beverage can” and “bottle can” or “bottle type beverage can”, made from a blank having the aforementioned characteristics, including a metal bottle called shape, that is to say whose main walls are not strictly cylindrical.
  • an aerosol can also known to those skilled in the art under the name of "aerosol can” or “aerosol dispenser”, made from said blank having the aforementioned characteristics, including an aerosol case said shape, that is to say whose main walls are not strictly cylindrical.
  • FIG. 1 represents the "horn profile", that is to say the shape of the developed perimeter of the top of the "cups" at the end of the first embossing, with, on the ordinate, the ratio of the horn height to the average height of the cup and, as abscissa, the angle a with respect to the rolling direction.
  • FIG. 2 represents the starting metal band A as well as its virtual division into regular hexagons B in which the C blanks are taken.
  • each blank is taken into identical regular hexagons whose two opposite sides are substantially perpendicular to the rolling direction, thereby forming a planar hexagonal system, as shown in FIG. four horns are added beyond and from the perimeter, in the zones of the hexagon left free, or whose principal axis forms an angle respectively of approximately 35 °, 145 °, 215 ° and 325 ° with the direction of rolling, as shown in Figure 3, each of a relative height of 0.3 to 0.8% with respect to said concentric circle of departure, and a maximum width given the available space, typically corresponding to half-height said horn to a minimum angular sector of substantially 25 ° having the top of the center of the blank.
  • Variant 1 corresponds to a constant blank radius of 69.3 mm as shown in solid lines in FIG. 4, ie a circular blank without any optimization.
  • stamping cups with a stamping punch diameter of 88.9 mm for an average cup height of 32 mm.
  • Figure 7 shows the profile curves of the cups obtained from the 4 variants of blank:
