Definitions

  • the invention relates to a method for producing pipes and profiles with over the length of variable wall thickness.
  • EP 0 788 849 A1 discloses a similar process for the production of pipes with sections of different wall thickness, in which an initial level Sheet metal by targeted partial wall thickness reduction areas of different Wall thickness arise with parallel course. This is the rolled Sheet metal cut, formed into a tube and along the abutting edges joined, in particular welded.
  • DD 244 083 A1 discloses a process for the production of pipes and hollow profiles with longitudinally changing inner diameter known.
  • the so differently rolled out metal strip is then in a profile plant profiled to the tube or hollow profile.
  • the periodic change from rolled to unrolled strip sections limited the rolling speed and can cause weak spots in the band at the Transitions lead.
  • the passage of the non-rolled band sections through the Rolling device is given no guidance of the metal strip. This is not an exact one Length measurement of the non-rolled band sections possible.
  • process control becomes the strip material after the high speed taking flexible rolls with a first winding speed on a Coil wound and for forming the strip material to the endless tube or Profile with a second lower winding speed, which on the forming optimized for endless tube or profile, unwound from this coil.
  • Systems for bending round to a tube in the longitudinal direction of the strip material or for forming into a profile in the longitudinal direction of the strip material with corresponding Roller assemblies with forming rollers are known in the art. Such systems include a plurality of consecutively in the production direction Forming rolls with regularly changing roll shape and / or axis position.
  • the tubes and profiles may be open in cross-section slotted tubes or Profile or cross-section closed tubes or profiles act.
  • preferred Procedure is the endless pipe or profile to the closed pipe or Longitudinal profile - especially in blunt joint - welded.
  • the inner diameter or cross-section are kept constant while the variable Wall thickness at the outer diameter or cross-section maps.
  • the individual Pipe or profile pieces formed after cutting to such an extent that they over the length have variable cross-sections.
  • Such pieces of pipe are used in particular Automotive engineering used in many applications, especially as a carrier with defined non-uniform deformation behavior (crash elements) or with defined non-uniform load behavior (bending beam).
  • the length remains constant over the length Round tubes formed so that at least one longitudinal section out of round, in particular is flattened laterally in cross section.
  • FIG. 1 An embodiment of such a tube is shown in the single drawing.
  • This shows in representation a an inventive tube 11 in longitudinal section.
  • first sections 12, 13, 14 with greater wall thickness and one-sided Flattening 18 and two sections 16, 17 of lesser wall thickness with undeformed circular cross section recognizable.
  • a longitudinal seam 19 is marked, which is not directly affected by the subsequent forming of the tube.
