Definitions

  • the invention relates to a method for producing a hollow profile with at least one flange by means of internal high-pressure forming.
  • An extruded profile is known, for example, from DE 10130794 A1, which has a flange and is subsequently subjected to internal high-pressure forming, the course and the direction of the flange over the length of the structural part only being dimensionally fixed during the deformation according to the internal high-pressure process.
  • an extruded hollow profile with a flange generally has the disadvantage that the hollow profile can only be bent and / or expanded poorly.
  • the reason for this is that the connection point of the flange on the hollow profile acts as a tie rod against the forming force.
  • the flange cannot be stretched sufficiently and therefore the hollow profile cannot be formed reliably.
  • DE 19905365 AI it is known to produce a hollow profile with a flange by roll forming from a sheet metal blank, the hollow profile then being subjected to internal high pressure forming.
  • the flange is determined in advance so that its position and dimensions are only formed during the hydroforming.
  • the hollow profile shown in this document has the disadvantage that there are sharp edges of the initial hollow profile, which may remain as visible residual edges or undulations due to the strong consolidation during the profile production process on the final hollow profile produced by the IHU process. The bending back or stretching out of such strongly hardened profile edges cannot be completely accomplished in the IHU process.
  • the method is characterized in that an initial hollow profile is made from a single sheet, at least one flange in the longitudinal direction of the initial hollow profile likewise being formed by corresponding folding or roll profiling of the sheet.
  • the sheet can in particular from a Sheet metal plate and / or a roll-profiled sheet, unwound from the coil.
  • the joint of the sheet is welded to form a closed initial hollow profile and the closed initial hollow profile is inserted into an internal high pressure forming (IHU) tool.
  • IHU internal high pressure forming
  • the inner contour of the hydroforming tool, on the one hand, and the hold-down force to be applied to the flange, which is then to be applied during internal high-pressure forming, on the other hand, are selected such that the position of the flange always remains unchanged with respect to the final hollow profile then formed.
  • the flange can be produced in different ways when the sheet is folded or rolled.
  • the flange is formed by doubling the material of the sheet during folding or roll profiling, that is to say that the sheet is folded over or roll profiled while forming the flange.
  • the sheet is folded or roll-profiled so that the two ends of the sheet form an overlapping joint to form the flange.
  • the sheet is folded or roll-profiled at one end to form the flange and the other end is shaped during folding or roll-profiling so that it abuts the transition region between the flange and the initial hollow profile.
  • the sheet is welded to one another in the region of its free ends. Since these free ends can lie in the area of the flange or can lie outside of this area, welding is carried out there in each case.
  • the weld seam is in any case outside the flange area in the initial hollow profile.
  • Hollow profiles produced by the process according to the invention are suitable, for example, for use in body construction as roof frames, sills, cross members or longitudinal and cross members in the body floor group, it being possible for the adjacent body components to be connected to the flange by classic joining methods, such as resistance spot welding.
  • Figure 1 shows schematically an IHU tool with a clamped flange.
  • 2a and 2b an initial hollow profile with different positions of the weld seam;
  • IHU tool 1 shows an IHU tool 1, which consists of an upper part 2 and a lower part 3. Both parts 2 and 3 form a cavity 4 which corresponds to the contour of the final hollow profile.
  • a metal sheet formed into an initial hollow profile 5 is inserted into this cavity 4.
  • the initial hollow profile 5 has a flange 6 which is clamped in a corresponding section 7 of the cavity 4.
  • the clamping can either take place with such a hold-down force that no material can flow from the area of the flange 6 into the end hollow profile, or that such a flow of material is permitted.
  • FIG. 2a and 2b show an example of an initial hollow profile 5, in which a flange 8 is formed by an overlapping joint of the free ends of the sheet.
  • the flange 8 can then be welded either by providing a weld 9 (FIG. 2a) in the joint region of the flange 8 or a weld 9 (FIG. 2b) in the course of the flange 8, transverse to it.
  • 3 also shows an example of an initial hollow profile 5, in which the flange 10 is formed by appropriately bending a free end of the sheet and welding the other free end in the transition region between the flange 10 and the initial hollow profile 5.
  • FIG. 4a Another possibility is to design a flange 11 of the initial hollow profile 5 in such a way that the sheet is folded over and thus overlaps in the area provided for the flange 11.
  • FIG. 4b Another possibility is to design a flange 11 of the initial hollow profile 5 in such a way that the sheet is folded over and thus overlaps in the area provided for the flange 11.
  • the weld seam 9 is located outside the flange in the region of the initial hollow profile 5.
  • Such an initial hollow profile with a weld seam 9 located outside the flange region is preferably to be used when a reflow of material from the area of the flange 11 is to be made possible during hydroforming.
