Definitions

  • the invention relates to a method for producing a torsion profile from a blank according to the preamble of claim 1 and a torsion profile according to the preamble of claim 5.
  • a plate is provided with a longitudinally directed U-shaped depression at a distance from its front ends.
  • the legs of the plate deformed in this way that are created next to the trough are subsequently bent over essentially parallel to one another and to the central longitudinal axis of the trough.
  • the bent legs, with their longitudinal edges in contact, are deformed in the form of a tube in the areas adjacent to the front ends of the plate and in the longitudinal section with the trough in an O-shape to match the contour of the trough.
  • the longitudinal edges of the deformed legs are welded together so that the torsion profile that is now finished is produced for further use.
  • Torsion profiles produced in this way have sufficient torsional strength, in particular for applications in the automotive sector, which is necessary for such torsion profiles in particular in safety-relevant areas in the automotive sector.
  • Torsion profiles inherently have the unpleasant property that, under certain circumstances, undesirable noises are generated under torsional loads, since the bent legs of the plate and the boundary walls of the trough made in the plate rub against each other in the middle length section, which can be subjected to torsion.
  • These noises can be unpleasant for the human hearing even lie in a painful frequency range, so that such torsion profiles are not suitable for the comfortable operation of a motor vehicle.
  • this object is achieved by a method with all the features of claim 1.
  • the object is achieved by a torsion profile with all the features of claim 5.
  • Advantageous embodiments of the invention can be found in the subclaims.
  • process step d) can also be carried out before one of process steps a), b) or c).
  • the board can have all possible contours.
  • the plate is rectangularly contoured, so that when the legs of the deformed plate are bent over, after a longitudinally directed U-shaped depression has been introduced into them at a distance from their front ends, they have approximately the same width over their entire longitudinal extent.
  • the bent legs are bent in such a way that they are arranged essentially parallel to one another and parallel to the central longitudinal plane of the trough. Due to the tubular deformation of the bent legs in the areas adjacent to the front ends of the board and the U-shaped deformation of the bent legs in the longitudinal section with the trough to match the contour of the trough, the longitudinal edges of the bent legs are arranged opposite one another over their entire length.
  • the tubular deforming should not be limited to a round, oval or similar geometry. Rather, it should be understood to mean any deformation, so that the end sections of the profile created in this way can be molded onto other components, whereby they are of course designed to be correspondingly torsionally rigid.
  • the invention is now characterized in that by introducing at least one spacer into the reshaped plate, the bent legs and the boundary walls of the trough extending in the direction of the longitudinal edges of the central longitudinal section are kept at least partially at a distance, with the deformed ones after the longitudinal edges have been joined Legs, the bent legs and the boundary walls of the trough are spaced apart in the central longitudinal section, which can be subjected to torsion in the torsion profile.
  • this ensures that the bent legs and the boundary walls no longer rub or slide against each other over their entire surface when subjected to torsional stress, so that the generation of noises, especially in frequency ranges that are uncomfortable or even painful for the human ear, is effectively reduced.
  • bent legs and the boundary walls of the trough extending in the direction of the longitudinal edges of the central longitudinal section are kept at a distance over their entire longitudinal extent. This ensures that the bent legs and the boundary walls no longer rub against each other or slide off at all in the event of torsional stress, so that the generation of noises, especially in frequency ranges that are uncomfortable or even painful for the human ear, is effectively avoided.
  • a protruding bead from the bottom of the trough is formed in the direction of the longitudinal edges of the central longitudinal section. This is sure to avoid that when joining or welding introduced energy input is not also welded to the bottom of the trough with the bent legs. As a result, a free space is formed between the bent legs and the bead in the area of the base of the trough, which prevents the limbs from being welded to the base of the trough.
  • the at least one spacer is introduced between the longitudinal edges of the bent legs.
  • the bent legs are then still in contact with the boundary walls of the trough before the spacer is introduced, but by inserting the spacer between the longitudinal edges of the bent legs, the bent legs are bent open, so that the trough is now between these and the boundary walls required distance is formed.
  • the gap that now appears between the bent legs and the boundary walls is sufficient to avoid the generation of noise when the central longitudinal section of the torsion profile is subjected to torsional stress.
  • the torsion profile according to the invention produced from a blank has a torsionally rigid tubular end section, a torsionally soft U-shaped central length section that forms a trough and transition sections changing from the U-shaped to the tubular cross-section between the central length section and the end sections, the central length section being designed in this way is that curved legs and in the direction of the longitudinal edges of the central longitudinal section extending boundary walls of the trough are arranged adjacent.
  • the torsion profile according to the invention is now characterized in that at least one spacer is provided, by means of which the curved legs are kept at a distance around the boundary walls of the trough in the central longitudinal section.
  • This configuration of the torsion profile according to the invention ensures that a gap is formed between the boundary walls of the trough and the bent legs of the profile so that in the event of torsion they cannot have direct contact with one another, so that noise is effectively avoided.
  • the at least one spacer is arranged between the longitudinal edges of the deformed legs. This ensures that such a spacer can simply be inserted into a gap between the longitudinal edges of the deformed legs, whereby the bent legs are again widened somewhat so that the gap is formed between the legs and the boundary walls of the trough.
  • torsion profiles with different distances between the legs and the boundary walls can be implemented, but the same manufacturing tools can be used. This is particularly advantageous because it means that a large number of production tools do not have to be kept available in order to produce different torsion profiles with different torsion properties.
  • the torsion property of the torsion profile can be adjusted by using the spacer accordingly.
  • the spacer is joined, in particular welded, to the longitudinal edges of the deformed legs.
  • Torsion profiles of this type can namely be manufactured particularly cheaply in terms of process technology.
  • the trough has a protruding bead which extends out of the bottom to form a free space in the direction of the longitudinal edges of the central longitudinal section. This effectively prevents the delimitation walls of the trough and the bent legs from being joined or welded to one another in an unintended manner when a high energy input into the material occurs during welding.
  • the torsion profile according to the invention is advantageously produced by the method according to the invention described above.
  • FIG. 1 an embodiment of a torsion profile 1 according to the invention is shown in a perspective view.
  • the torsion profile 1 has torsionally stiff, essentially circular, tubular end sections 2, a torsionally soft U-shaped central length section 3 and transition sections 4 that change between the central length section 3 and the end sections 2 from the U-shaped to the tubular cross-section.
  • the torsion profile 1 is provided with a trough 11 in the central longitudinal section 3, so that the central longitudinal section 3 is U-shaped through this trough 11.
  • a bottom 47 of this trough is arranged opposite longitudinal edges 7, which are designed in the shape of ears, the torsion profile 1 in the central longitudinal section 3 thus being designed with two layers or double walls.
  • the torsion profile 1 is made from a rectangular metal plate 8, of which in Figure 2 one half is shown.
  • the other half is designed as a mirror image, so that in the following Figures 3 to 5 only this one half is illustrated and also described.
  • the areas 10 of the plate 8 adjacent to the front ends 9 are first deformed in an S-shape.
  • the tools used for this are not shown in more detail.
  • the blank 8 deformed in this way is provided with a U-shaped depression 11 between the S-shaped regions 10.
  • the Plate 8 placed between an upper tool, not shown here, and a lower tool, also not shown.
  • the upper tool defines the inner contour of the trough with a bead, while the lower tool with a channel serves as a counter bearing and defines the outer contour.
  • the trough 11 is introduced centrally into the plate 8 in such a way that legs 14 and 15 of approximately equal width are formed adjacent to the trough 11.
  • a deformed board 8 is in the Figure 3 shown.
  • the approximately constant legs 14 and 15 of the plate 8 next to the trough 11 are bent over essentially parallel to one another and to the central longitudinal plane of the trough 11.
  • a correspondingly reshaped plate 8 is in the Figure 4 shown.
  • Reshaped blank 8 is then reshaped using further tools so that the legs 14 and 15 are deformed tubularly with contact of their longitudinal edges 35 and 36 in the ends of the reshaped blank 8 and the central longitudinal section 3 with the trough 11 is deformed into a U-shape.
  • Such a deformed plate 8 is shown in FIG Figure 5 shown.
  • FIG Figure 6 now shows a cross-sectional view of FIG Figure 5 deformed plate in the area of the central longitudinal section 3. It can be seen very clearly here that the legs 14 and 15 are in contact with the boundary walls 54 and 55 of the trough 11 and make contact with them. The longitudinal edges 35 and 36 of the legs 14 and 15 are opposite one another, forming a gap 42. Opposite this gap, the trough 11 is provided with a bead 48 in its bottom 47, so that a free space 49 is formed between the legs 14 and 15 and the boundary walls 54 and 55 in the region of the gap 42.
  • a spacer 50 is inserted into the gap 42.
  • the legs 14 and 15 are widened again somewhat so that they are no longer in contact with the boundary walls 54 and 55 of the trough 11.
  • the configuration of a blank 8 formed in this way is shown in FIG Figure 7 It can be clearly seen that a gap is formed between the leg 14 and the delimiting wall 54 and between the leg 15 and the delimiting wall 55.
  • the spacer 50 is materially connected to the legs 14 and 15, forming joints 61 and 62, which are formed as weld seams during welding. After the joining, the torsion profile 1 according to the invention is now completed.
  • This torsion profile 1 has in its middle length section 3, which can be exposed to torsional stress, no contacts between the legs 14 and 15 with the corresponding boundary walls 54 and 55, so that when the torsion profile is subjected to torsional stress, noise is generated due to legs 14 and 14 rubbing against one another 15 and boundary surfaces 54 and 55 is avoided.
