Definitions

  • the invention relates to a method for producing a container body by deep drawing an aluminum strip, which with Plastic material is laminated on the inside and painted on the outside and a device for performing the method.
  • Rigid cans for example fish cans, become container bodies made of flat material, especially aluminum tape or tinplate tape, in the material thickness of approx. 200 ⁇ m to avoid deep-drawn from wrinkling in 2 to 3 stages.
  • the container body usually consists of an alloy of type 3004 im Condition H44.
  • container bodies for pet food made from the alloy 8011 known in a material thickness of 110 microns in the state H0 can be deep drawn in one step. These materials have an insufficient dent resistance, so that according to the usual impact and compression stresses on the transport routes the container body has numerous dents.
  • the alloy of type 3004 according to the invention is characterized by a special ratio formation of the individual alloy parameters. This ratio formation has a particularly favorable effect on the deep-drawing ability and on the formation of the structure (in particular the grain distribution).
  • the structure according to the invention is characterized by a characterized special phase distribution, which thereby achieved is that after the rolling process a heat treatment (briefly annealed) is carried out so that the material is partially (not completely) is recrystallized.
  • the structure of the composite material according to the invention consists of 85 ⁇ m aluminum with a lining of 30 ⁇ m polypropylene. The composite is then supplemented by an outer coating.
  • the polypropylene liner can also be covered with a Extrusion coating to be replaced. This has the advantage improved adhesion, good temperature resistance and freedom from solvents.
  • the paint (outside) is applied with a layer thickness of 1.5 to 4 g / m 2 . It must be ensured that the paint type shows only slight roughening during deep drawing and a low water absorption capacity during sterilization. This is achieved through a particularly low porosity and good lubricity of the paint.
  • the deep-drawing tool is shown in plan view.
  • machine screws 15 can the horizontal Base plate 16 of the upper tool with the perpendicular to it arranged tubular wall 17 are connected.
  • the wall 17 has a wall slope I, the angle between Wall slope and vertical axis S between 5 and 10 ° preferably Is 8 °.
  • the lower tool according to FIG. 3 is analogous to the upper tool 1 with a central bore 18 for the control cylinder fitted.
  • the lower tool base plate 19 has cutouts 3.1 to 3.4, which are rotationally symmetrical to the bore 18 are arranged.
  • In sections 3.1 - 3.4 are tiltable Facets arranged in the bearing points 20-23.
  • Figures show the same part in a different cross-sectional shape 4a, 4b, being analogous to the wall slope shown in FIG I an inclined surface A with the corresponding angles to Vertical T is arranged on the outer wall of the tool part 24 is.
