Definitions

  • the invention relates to a profile of a strip-shaped rolling stock having a starting material thickness, with a longitudinal axis and with at least one bend, wherein the profile has at least one thickness-reduced section with a material thickness which is smaller than the starting material thickness.
  • Profiles such as those used for example in the installation technology, z. B. made of strip-shaped rolling stock by forming in a roll forming.
  • the profiles are in cross section, for example, round, polygonal or C-shaped.
  • the strip-shaped rolling stock is widened in the width direction relative to the initial width of the strip-shaped rolling stock.
  • the at least one thickness-reduced portion of the rolling stock is arranged such that it comes to rest in a statically low-stressed area or near the neutral line in the main load directions of the profile.
  • the reduced-thickness portion of the rolled material runs along the longitudinal axis of the created profile.
  • a disadvantage of the known solution is that for optimal utilization of the material-saving effect the largest possible reduction in thickness is desired.
  • this local thinning of the rolling stock can lead to stiffness losses, whereby the maximum possible reduction of the thickness is limited.
  • the object of the invention is to provide a profile of a strip-shaped rolling stock, which is both material-saving and stiffness-optimized.
  • At least one thickened region is provided in the region of the at least one bend of the profile with a material thickness which is greater than the starting material thickness.
  • the stiffness of the profile is improved in a highly loaded area of the material-optimized profile.
  • This profile has a comparable contour compared to a profile of a strip-shaped rolling stock with a constant material thickness on a low material usage, the stiffness loss compensated by the at least one thickened area or by the resulting local stiffening of the profile at least partially and possibly even the stiffness of the profile opposite a profile of a strip-shaped rolling stock of constant material thickness is increased.
  • the at least one thickened region is a material accumulation and is formed in the same rolling step in forming the thickness reduction with correspondingly formed rolls in the cold rolling process.
  • thickened regions are provided on both sides of the at least one thickness-reduced section. If the profile has a plurality of thickness-reduced sections, regions or accumulations of material thickened on both sides are advantageously provided on each thickness-reduced section.
  • the accumulations of material are formed, for example, on one side or on both sides of the strip-shaped rolling stock and thus of the formed therefrom profile.
  • the at least one thickened region is provided adjacent to the at least one bend, which allows for easy forming of the strip-shaped rolling stock while at the same time improving the rigidity of the profile despite the thickness-reduced sections.
  • the profile preferably has a cavity, which is at least partially enclosed by side walls, and the at least one thickened region faces this cavity.
  • the at least one thickened region is thus not provided on the outside on the profile, so that the function or the arrangement of the profile is not limited by the accumulation of material due to the thickened region.
  • the material thickness of the at least one thickened region preferably corresponds to 1.1 to 2.0 times the starting material thickness of the strip-shaped rolling stock, which ensures an advantageous improvement in the rigidity of the material-optimized profile.
  • the at least one thickened region has a material width perpendicular to the longitudinal axis of the profile, which corresponds to 1.0 to 5.0 times the starting material thickness of the strip-shaped rolling stock, which likewise ensures an advantageous improvement in the rigidity of the material-optimized profile.
  • Profile 11 shown has a C-shaped cross-section with two side walls 12 extending parallel to one another and a connecting section 13 connecting the two side walls 12. Between the side walls 12 and the connecting portion 13 a bend 17 is provided in each case. The free ends 14 of the side walls 12 are bent inwards and thus each have a bend 18. The side walls 12 partially enclose a cavity 19. The profile 11 extends along a longitudinal axis 15th
  • the profile 11 is made of a strip-shaped rolling stock having a starting material thickness W and has in the side walls 12 two thickness-reduced portions 16 with a material thickness D which is smaller than the starting material thickness W.
  • a thickened region 21 or 22 or a material accumulation with a material thickness H and a material width B is provided on both sides, which extends transversely to the longitudinal axis 15 of the profile 11.
  • the material thickness H of the thickened regions 21 and 22 is greater than the starting material thickness W of the strip-shaped rolling stock.
  • the thickened regions 21 and 22 face the cavity 19 and extend along the longitudinal axis 15 of the profile 11.
  • the thickened region 21 in the region of the bend 17 of the profile 11 is arranged directly in the bend 17.
  • the thickened region 22 in the region of the bend 18 of the profile 11 is provided directly adjacent to the bend 18.
  • the material thickness H of the thickened regions 21 and 22 corresponds to 1.1 to 2.0 times the starting material thickness W of the strip-shaped rolling stock.
  • the material width B of the thickened regions 21 and 22 corresponds to 1.0 to 5.0 times the starting material thickness W of the strip-shaped rolling stock.
  • the thickened portions 21 and 22 are respectively disposed between the reduced thickness portion 16 and the bends 17 and 18, respectively, with the thickened portions 22 being provided near the bend 18, respectively.
  • the thickened portions 21 and 22 are each arranged symmetrically on the profile 11. However, this is not absolutely necessary for improving the rigidity of a material-optimized profile 11.
  • the arranged on a side wall 12 and / or the opposite thickened portions 21 and 22 may also have different dimensions or be arranged asymmetrically. Furthermore, not all thickened areas need to protrude in the same direction. As shown schematically by the dashed lines, thickened regions 23 may also be directed outward, ie, facing away from the cavity 19.
