Definitions

  • the invention relates to a flat bar or flat profile bar made of metal, which is cambered about a bending axis whose radius is greater than 1000 mm, transverse to its longitudinal extent, wherein the bending axis is parallel to a broad side of the flat bar or parallel to a broad side of a leg of the flat profile bar.
  • flat bars or flat profile bars for example, have L-shaped cross-section of sheet steel or aluminum sheet.
  • the desired shape of the flat bar or flat profile bar is first produced by a punching process, molding process, punching process and bending process.
  • the finished in this manner flat bar or flat bar is then cambered.
  • the crowning axis lies at a large distance from the flat bar or flat profile bar, wherein the Distance may be, for example, 2 meters or more.
  • the crowning is required to give the flat bar or flat bar the shape desired by the manufacturer.
  • the present invention seeks to provide a flat bar or flat bar generic type that is dimensionally stable when bombing or after bombing its desired shape true to size, without the need for reworking the flat bar or flat bar and without that complex tool adjustments are required.
  • the arrangement of the embossing zones is provided only on a broad side of the flat bar.
  • the embossing zones are preferably provided in all legs of the flat profile bar, but only on the side, which allows an arrangement of embossing zones in the intended use of the component.
  • embossing zones are formed in the compressed inner skin of the flat bar or flat profile bar.
  • the embossing zone can also be designed in such a way that the embossing zone is formed by embossing points arranged next to one another in a row.
  • a plurality of embossing zones are formed distributed parallel to one another over the length of the rod, wherein they are aligned symmetrically to the rod center.
  • a flat profile bar made of sheet metal, such as steel or aluminum can be seen.
  • This flat profile bar 1 is cambered transversely to its longitudinal extension, wherein the bending axis is parallel to a broad side 2 of the one leg of the flat profile bar 1.
  • the radius of the bending axis for the crowning is significantly more than 1 meter, for example 5 meters.
  • the embossing zones 3, 4 are formed in the stretched outer skin of the corresponding profile section.
  • the embossing zone is formed by a continuous material depression, in particular from FIG. 4 is clear.
  • a plurality of embossing zones 3,4 are formed parallel to each other and distributed over the length of the respective rod, wherein they are aligned symmetrically to the rod center.
  • the rod center is indicated at 6.
