Definitions

  • the present invention relates to a method for manufacturing a closed profile, for example in the form of a pipe in a profile structure.
  • US 4 649 728 shows integral joint forming of work-hardenable high alloy tubing.
  • a pre-form tube is cold forged or cold rolled from the outside using a counterstay within the tube in order to increase the strength along substantially its entire length and substantially uniformly.
  • a profile material is not chosen or the manufacturing process is not controlled so that you achieve any substantial strategical variations in thickness of the material of the final product.
  • a profile material is not chosen or the manufacturing process is not controlled so that you achieve any substantial strategical variations in thickness of the material of the final product.
  • the object of the present invention is to provide a method for manufacturing a closed profile in a profile structure, for example a pipe that is constituted by iron and alloyed to provide a strong strain hardening during plastic cold forming in combination with maintaining a good ductility of the alloy at the same time as the pipe achieves a yield point of above 1000 MPa as the final product.
  • a closed profile is manufactured according to a method through hydroforming and/or mechanical treatment of the same, to provide a strategically varying wall thickness axially and/or in the cross-section of the profile.
  • a method and device for manufacturing a closed profile in a profile structure and a closed profile manufactured according to the method have now been provided that in an excellent manner fulfil their purposes at the same time as the manufacture can take place very rationally and at low cost.
  • the profile which is manufactured according to the invention, with varying wall thickness and/or diameter the weight of the profile can be reduced to more than half the weight of profiles in previously known construction solutions. Examples of such solutions may be different girders and frame structures in cars and other means of conveyance and also other components where closed profiles, for example in the form of pipes, may be incorporated.
  • the closed profile is constituted for example in the form of a pipe that is manufactured from a metal material of iron, which is alloyed with chromium, nickel and carbon in predetermined proportions.
  • the iron is alloyed with 17% chromium, 7% nickel and 0,1% carbon, wherein a strong strain hardening is obtained when plastically cold forming the profile in combination with maintaining a good ductility of the alloy.
  • the alloyed metal material forming the profile is formed through hydroforming and/or through expanding preferably by means of a mandrel with a cylindrical or other shape or through shrinking through axial elongation by pulling with or without a matrix, in order to increase the yield point of the metal material from an original, low yield point of about 300 MPa to a final product that completely or partially obtains a yield point of more than about 1000 MPa.
  • a closed profile in which a closed profile is manufactured with varying diameter
  • the pipe is expanded along half its length to a diameter of 60 mm, wherein the wall thickness of the pipe is decreased to about 1.5 mm along said half of the pipe and the yield point of the pipe can be increased to 1000 MPa or more at the same time as the other half of the pipe is left untreated.
  • the wall thickness and/or the circumference of the final closed profile may also be varied axially by applying two or more profiles partially into each other with the short profile external on the longer profile.
  • the wall thickness and/or the circumference may be varied further after the forming of the closed profile by using welding to join so called starting profiles with walls of different thickness and/or with different diameters.
  • the wall thickness may be varied in the same cross-section, so that the material will be strategically placed just over the areas where an expected maximum strain may take place.
  • As starting material for the closed profile according to the invention a metal material of the above-mentioned alloy having low strength is used.
  • the material in the profile is cooled to or is kept at a controlled temperature before and during the forming operation to achieve a controlled, maximal strength independently of the degree of deformation during the forming operation.
  • the temperature that the material is cooled to or the temperature that is maintained during the forming operation is -196° ⁇ T ⁇ 70°C.
  • the final product is cooled to or is kept at a controlled temperature for achieving a controlled maximal strength independently of the degree of deformation during the forming operation.
  • the temperature that the final product is cooled to or the temperature that is maintained during a limited time after the forming operation is -196° ⁇ T ⁇ 70°C.
  • the profile described in the application intended to be incorporated in a current profile structure may be constituted by any closed profile design intended to be incorporated in the current profile structure.
