Definitions

  • the invention relates to a method of the type specified in the preamble of claim 1.
  • Components made of lightweight materials are increasingly used in vehicle construction in order to reduce the component mass with sufficient strength and rigidity. But they are also used in many areas of mechanical engineering application and characterized by the resolution of the compact and solid structure in an open or closed-cell structure.
  • metal mounting elements such as screws, bolts, pins od.
  • suitable joining methods are needed, since the mounting elements can not be easily permanently attached to the components.
  • Gluing is one of the low-heat joining methods, in which no local weakening of the joining zone but a planar cohesive connection of the joining parts takes place. Their strength is usually higher than that of the cellular material.
  • the joining method "gluing" in particular in mixed construction, d. H. have multifunctional properties when using different metallic and / or non-metallic materials and additionally perform tasks such as electrochemical insulation and sealing function. Disadvantages with regard to the process speed are the curing times, which are often several hours at room temperature, of suitable, in particular thermoset reaction adhesives. A shortening of the
  • Curing times would indeed be possible by increasing the curing temperature, but requires further expenditure on equipment and financial commitment.
  • a method of the type described above is known (DE 695 03 284 T2), in which a plate-shaped, made of foam or honeycomb material component is covered on opposing broad sides with cover layers or thermoplastic material and provided with a specific for receiving an insert recess.
  • the insert is made of thermoplastic material and has at its axial ends so-called sacrificial edges which are plasticized by ultrasonic vibrations and melted with the edges of the two cover layers adjoining the recess.

  • the connection must not be made surface by contacting the insert with the component at the intended broadsides, but rather can be made substantially voluminous in the recess itself by means of an intermediate layer of thermoplastic material. If a component made of a (metallic) cellular material is used, then there is the further advantage that the thermoplastic material can penetrate deep into the pores of the material and thereby form a positive connection with the latter. The same applies to the side of the insert when it is provided at its protruding into the recess outer surface with suitable for receiving the thermoplastic material wells.
  • the joining method according to the invention requires neither a recess passing through the component nor any cover layers and can be carried out largely independently of the materials provided for the component and the insert.

  • ABS acrylonitrile butadiene styrene
  • the inserts 6, 16 should eventually consist of a metal or a metal alloy, although other, sufficiently hard and non-thermoplastic meltable plastics would be suitable.
  • the invention is not limited to the described embodiments, which can be modified in many ways. This applies in particular to the described dimensions and geometric shapes of the various parts. It should also be noted that the outer contour of the introduced into the recess 2 portion of the insert 6, 16 does not have to coincide with the inner contour of the recess 2 surrounding circumferential wall identical. It is only necessary that the body 5 has a sufficiently large volume to the space between the recess wall and the outer surface of the insert 6, 16 as completely as possible, ie volumetric fill. For this purpose, it would also be possible to form the body 5 substantially solid and instead form the insert 6, 16 at least on its underside as a hollow body, so that excess thermoplastic material can be accommodated in a cavity of the insert.
  • the axial height of the body 5 could also be smaller than the depth of the recess 2.
  • the body 5 z. B. formed as a hollow body and optionally with a slight interference fit on the insert 6, 16 is pushed until it z. B. from below against the flange 15th (Fig. 5) abuts.
  • the measure K 1 (FIG. 5) to be slightly larger than the dimension A; to choose. Also combinations of these two variants are possible.

Abstract

L'invention concerne un procédé pour fixer un insert (6), pouvant être utilisé comme élément de montage, dans un composant (1) constitué d'une matière légère, en particulier d'une matière métallique cellulaire. Le composant (1) est, à cet effet, pourvu d'un évidement (2) dans lequel est inséré un corps (5) en matière thermoplastique. L'insert (6) est, pour être introduit dans l'évidement (2), fixé à une sonotrode (9) qui est utilisée pour la plastification de la matière thermoplastique et ainsi pour l'assemblage rigide par liaison de matière et/ou de forme de l'insert (6) avec le composant (1), dans la zone de l'évidement (2).
