Definitions

  • the invention relates to a method for producing Metal profiles.
  • the present invention is therefore based on the object to create a process that is easy to manufacture of metal profiles with different cross sections mechanical properties.
  • the object is achieved in that a Starting material with different over the cross section Material properties formed into a profile by roll forming becomes.
  • the invention is based on the idea that those desired on the profile different cross-sectional dimensions and / or different material-specific properties already in a simple to produce starting material to provide and the simple and inexpensive for the profile design Use roll forming technology. In this way tubes and other profiles can be manufactured not only have a different cross-sectional thickness, but across the cross-section also from different ones Materials are built up.
  • the starting material preferably consists of at least two Sheet or profile strips welded together on the long side with different material properties or - dimensions. If only different thicknesses are desired on the profile, so two or more sheet metal or profile strips different thicknesses welded together along the sides be.
  • the method according to the invention is particularly suitable for the production of aluminum profiles, i.e. the tin or Profile strips are made from an aluminum alloy.
  • Suitable alloys are, for example, alloys from the series AA5xxx (AlMg), AA6xxx (AlMgSi) or AA7xxx (AlZnMg, AlZnMgCu).
  • the individual sheet or profile strips can not only have different thickness, but also from different Materials exist. This makes it possible to produce so-called intelligent profiles, their thickness and material-specific properties depending on the desired Stiffness, strength or from design Reasons to use where it depends on the design or is required by design.
  • the starting material can, for example, be welded to one another laterally Roll strips exist. That on this Pre-made starting material is especially for continuous production of profiles suitable, whereby for Manufacture of pipes and other profiles with closed Cross-section of the roll-formed metal profiles continuously be welded into a hollow profile. Suitable for this Welding processes are, for example, laser radio frequency or electron beam welding.
  • extruded profile strips can also be used or profiles with a preformed cross section be welded together laterally.
  • a starting material 10 shown in FIG. 1 has one central strip 12 with a thickness d of, for example, 2 mm and 12 side strips projecting laterally from the central strip 14, 16 of a smaller thickness e, for example 1 mm on.
  • the raw material 10 becomes cross-sectional in the roll forming process curved so that the longitudinal edges 18, 20 of the two side strips 14, 16 each other to form a cross-section approach closed profile.
  • the starting material 10 bent into a tube and the two longitudinal edges 18, 20 over a longitudinal weld 22 to form a tube 24 connected with each other.
  • the tube 24 has a thickness d of central strip 12 corresponding thickening 26, the remaining cross section of the tube 24 corresponds to the small Thickness e of the side strips 14, 16.
  • the profile 27 shown in Fig. 3 with also closed Cross section can be done in the same way as the pipe 2 by roll forming from the starting material 10 produce.
  • the starting material 10 can be made of an aluminum alloy, for example be extruded.
  • Another source material 10 which is particularly for continuous manufacturing of roll-formed profiles, for example from rolled strips that are welded to each other laterally are.
  • a first rolled strip would central strips 12 correspond to the thickness d.
  • On the side this first rolled strip would be a further rolled strip with the Dimensions of the two side strips 14, 16 welded.
  • the variant of a starting material 30 shown in FIG. 4 has a first stepped profile 32, on the side a strip profile 34 is welded on.
  • the tiered profile 32 consists, for example, of an alloy of the AlMgMn type with high elongation, the strip profile 34 for example a high-strength alloy of the type AlZnMg.
  • the main one Deformation of the starting material 30 by roll forming takes place according to the better formability of a AlMgMn alloy compared to an alloy of the type AlZnMg am Flat profile 32.
  • the made from the high-strength alloy Strip profile 34 leads to a on the roll-formed profile Area with high strength.
  • the method according to the invention is not limited to that in FIG Drawing illustrated embodiments of starting materials limited. Basically, the starting materials from any number of different rolled strips Thick or with extruded profiles any cross-section.
