Definitions

  • the invention relates to a rivet element for attachment to a component, in particular to a component made of fiber composite material, an assembly component comprising a corresponding rivet element and a component, and a method for attaching a rivet element to a component and a method for producing a rivet element.
  • connecting elements in particular rivet elements
  • components made of sheet metal or fiber composites it was previously assumed that it is necessary to form an opening for the connecting element in preparation of the fastening process in the component.
  • such an approach involves considerable disadvantages, since discontinuities in the material result in discontinuities which significantly weaken the material precisely where a particularly high material strength is actually required for reliable anchoring of the connecting elements.
  • the object of the invention is therefore to provide a way to attach rivet elements to components such that the components do not have to be weakened in a disadvantageous manner, and it should be possible in particular to attach fasteners to components made of fiber composites.
  • the rivet element according to the invention has a flange section in a mounted state on the component and a rivet section.
  • the rivet section comprises a tip which converges in a direction away from the flange section, at the end remote from the flange section of which an expanded end section is provided.
  • the rivet section By forming the rivet section as a tapered tip, it is possible to first press the rivet element with the tip into the respective material. The widening of the end section at the end of the tip facing the component ensures that it undergoes progressive spreading when the rivet section is pressed into the component through cooperation with the material of the component, which also covers the tip in the further course of the pressing-in process. When the rivet section is pressed in, its increasing deformation thus takes place to form a riveted connection.
  • the flared end section ensures that the deformation of the rivet section takes place in a controlled manner, namely in such a way that the rivet section is flanged to the outside.
  • the rivet element according to the invention is therefore particularly suitable for components made of fiber composite materials, which are at least temporarily in a state in which the material is sufficiently soft or "doughy". This will be discussed in more detail below.
  • the rivet element according to the invention can be used in conjunction with thermoset or thermoplastic materials or components.
  • Another advantage of the invention is that it is not absolutely necessary to glue the connecting element to the component. However, a gluing can of course be additionally provided.
  • a waist-forming constriction is provided between the end portion and the convergent tip.
  • the expansion of the end portion is carried out so that a minimum outer circumference of the rivet portion is not present at its free end, but between the tip and the free end of the end portion, which ultimately defines the free end of the rivet.
  • the end portion diverges at least in sections in the direction away from the flange portion.
  • the rivet portion may comprise a plurality of, in particular tongue-shaped and preferably interconnected, segments that are movable apart upon expansion of the rivet portion during assembly of the rivet member to make a rivet connection.
  • the segments each narrow along a central axis in the direction of the flange portion away.
  • At the junctions of the segments can be provided in the manner of predetermined breaking parts - for example by a smaller wall thickness - each a targeted material weakening.
  • the expansion of the tip is in this case associated with breaking the tip to move the segments apart.
  • the segments may be unconnected at least in some areas and either abut one another or slightly spaced apart, so that together they form the tip used for pressing into the component in the initial state and can then be moved apart without breaking material.
  • the rivet section comprises a plurality of tongue-shaped segments in particular, which together form the tip and which are movable apart when the tip is widened.
  • the rivet section is formed by reshaping an originally hollow-cylindrical basic body. That is, the basic body is transformed into the tip during the manufacturing process of the rivet element.
  • the material of the main body undergo folds, so that the tip produced by the forming process has a contour of a flower or a rosette in a cross section perpendicular to the longitudinal axis of the rivet element.
  • the end section can also be formed by the forming process. However, this is preferably done in a separate step.
  • the rivet portion may have a substantially cylindrical portion, which is followed by the tip.
  • the cylindrical portion is arranged in particular between the flange portion and the tip.
  • the flange portion may be provided with means for preventing rotation. These means are, for example, depressions and / or ribs which extend in the radial direction.
  • the rivet element according to the invention can be designed as a nut element or as a bolt element.

  • the invention can be used advantageously both in conjunction with fiber composites with relatively short fibers and materials with relatively long fibers. Components with short fibers can be produced in an injection molding process. Here, the material mixture is well deformable, so that the tools used in the manufacture of these components can be used simultaneously for the attachment of rivet elements. Fiber composites with long fibers can be made by lamination, ie, by criss-crossing individual layers with directional fibers.

  • the rivet section 1 1 can be even more waisted in certain cases, but usually a less severe constriction is sufficient to achieve the desired effect.
  • the end portion 12b has a very slightly divergent, almost coaxial configuration, since even a slight expansion of the end portion 12b ultimately leads to an outward bending of the rivet portion 1 1 when pressed into the component 51.
  • the rivet section 1 1 is formed by a plurality of tongue-shaped segments 13 which extend from the flange section 21 and which form the tapered tip 12 a of the rivet section 1 1 in the manner of a closed bud, the end section 12 b - figuratively speaking - opening the bud implies.

  • FIG. 7 shows the planar base 53, which serves as a support surface for the component 51 during the pressing in of the rivet element 10. In contrast to conventional methods thus no die is required, which causes the beading of the rivet section 1 1.
  • the degree of expansion of the end portion 12b suitable for the particular application - i.e. their depth in the axial direction and their width defined by the slope of the flanks of the mandrel - depends, inter alia, on the material and the thickness of the component, on the mechanical properties of the rivet portion 11 and on the forces of depression / speeds.
  • the widening of the end section 12b does not just lead to an uncontrolled deformation of the rivet section 11, but rather initiates the spreading of the rivet section 11, with the appropriate coordination of the abovementioned parameters, which finally results from the interaction with the flat support surface 53 is bent over to complete the riveted joint.
  • the degree of expansion is to be chosen so that on the one hand it is not too big. Then, the rivet portion 1 1 may spread too quickly and may not fully penetrate the component 53. On the other hand, the expansion must not be too small, since otherwise it is not reliably ensured that the spreading of the rivet section 1 1 starts fast enough. However, it has been shown that often even a comparatively small widening of the end section 12b leads to the desired deformation of the rivet section 11 when it is pressed into the component 51. The manufacturing process described above is assisted when the material is at least temporarily heated and thus softer so that the rivet element 10 can be more easily pressed into the material.
  • the invention thus makes it possible to attach rivet elements, in particular to components of fiber composite materials also referred to as "organo-nobleche", without openings having to be formed in the material for the rivet elements. Adverse weakenings of the material are thereby avoided in an advantageous manner.
