Definitions

  • the present invention relates to a sleeve insert for a plastic component according to the preamble of claim 1.
  • the invention also relates to a method for installing such a sleeve insert in a plastic component.
  • a generic sleeve insert which is designed as a threaded insert and consists of a sleeve-shaped deep-drawn, embedded in the component material threaded element.
  • the sleeve insert has an integrally formed, over the shank portion radially projecting flange on the component outside end, which allows both a precise centering and a rotationally fixed anchoring of the threaded insert with the component by bending.
  • connection insert is fixed in the bore of a component, wherein the connection insert is pressed with a conical portion in a conical portion of the bore.
  • connection insert at the wider end of the conical portion on a laterally projecting flange portion which is supported in the pressed state on a radial bearing surface of the component.
  • connection insert has an axial projection integrally formed on the narrower end side of the conical section or on the end side of the flange section and projecting beyond the surface of the component.
  • a method for joining a composite sheet to a metallic substrate wherein the composite sheet mini- at least one metallic cover layer and at least one non-metallic layer which consists of a plastic.
  • the composite sheet while an opening is introduced and additionally provided at least one joining element, which is introduced into the opening of the composite sheet.
  • the joining element is formed as a metallic sleeve, which is deformed such that it forms a positive and non-positive connection with the composite sheet.
  • the metallic sleeve With the end pointing to the substrate, the metallic sleeve is joined to the substrate in a material-locking manner using a filler material, this filler material being arranged in the interior of the sleeve. In this way, in particular a disadvantageous welding process can be avoided.
  • the present invention therefore deals with the problem of providing a sleeve insert of the generic type an improved or at least one alternative embodiment, by means of which in particular the tolerance problem can be at least defused.
  • the present invention is based on the general idea, with a sleeve insert for a plastic component, consisting of a shank portion and a bendable flange portion, to provide a material and / or cross-sectional weakening, which facilitates bending over of the flange portion already installed in the plastic component state.
  • the invention proposes to carry out the forming process only in the finished plastic component. For this purpose, the sleeve insert is pushed with a shaft portion in the plastic component and then the flange portion sunk by means of a corresponding punch in a groove provided for this purpose on the plastic component.
  • the sleeve insert according to the invention has the previously described material and / or cross-sectional weakening.
  • Such a material and / or cross-sectional weakening simplifies or facilitates the bending of the flange section considerably and therefore makes it possible to carry out the forming process of the sleeve insert in the already finished plastic component.
  • the cross-sectional weakening is formed as a groove or a slot.
  • a cross-sectional weakening may be formed, for example, as an annular groove, as a radial slot or as an axial slot.
  • An annular groove is therefore usually arranged at the transition between the shaft portion and the flange portion and creates there a kind of hinge, which allows in the manner of a film hinge an exact and predefined bending of the flange portion. It is possible, for example, that the entire sleeve insert in one piece, that is formed from a single piece. In particular, when providing an axial slot, it is also conceivable to rotate or roll the sleeve insert by a simple winding process of a metal blank (metal sheet or flat plate).
  • Such a sleeve insert can thus be deformed comparatively easily, that is to say stress-free and low-power, without further cross-sectional weakening in its flange region, although the flange section also has to be plastically deformable for a long time.
  • a multi-part sleeve insert it is also conceivable to form this from a kind of modular system in which different shaft sections and / or different flange sections are provided.
  • a connection between a respective flange portion and an associated shank portion can be done for example by a simple screwing, gluing, pressing or nesting.
  • the sleeve insert is designed as a threaded sleeve. This makes it possible, in an otherwise soft and rather unsuitable for a screwing plastic component to provide a solid anchoring option, via which, for example, an additional unit is fixed by a screw.
  • the sleeve insert may also be formed of two sleeve sections and a spring arranged therebetween, which clamps the two sleeve sections away from each other in the axial direction.
  • the two sleeve sections are pushed in the plastic component to each other butt, whereby the interposed spring is compressed.
  • the spring arranged therebetween After releasing the two sleeve sections due to the spring arranged therebetween, at least slightly spring back, with pressed in a cultivation of an additional unit to the plastic component of the sleeve portion back into the associated bore on the plastic component and about the Spring is tensioned.
  • the present invention is further based on the general idea of inserting a sleeve insert, which is usually formed as a metallic sleeve insert, with its shaft portion in a plastic component and only in the inserted state at its flange to bend and thereby fix.
  • a sleeve insert which is usually formed as a metallic sleeve insert
  • the shaft portion in a plastic component and only in the inserted state at its flange to bend and thereby fix.
  • 1 a is a view of a first embodiment of a sleeve insert according to the invention in the uninstalled state

  • 2a is a view of a sleeve insert with an inner sleeve and a
  • FIG. 2b is a representation as in Fig. 2a, but in the installed state
  • FIG. 3 shows a sectional view through a sleeve insert according to the invention with flange sections attached in the left-hand representation and in the right-hand illustration with a plurality of sleeve sections and a spring arranged therebetween,
  • Fig. 4 shows a device for installation of the sleeve insert according to the invention in a plastic component.
  • a sleeve insert 1 for a plastic component 2 (cf., Fig. 4) consists of a shaft section 3 and at least one bendable flange section 4.
  • the sleeve insert 1 now has a material and / or cross-sectional weakening 5, which facilitates bending of the flange portion 4 and thus fixing of the sleeve insert 1 in the plastic component 2.
  • the cross-sectional weakening 5 can be designed, for example, as a groove, in particular as an annular groove (cf., FIGS. 1 a and b) or as a slot (compare FIGS. 2 a and b).
  • both a radial slot and an axial slot may be provided, which is particularly useful in providing a continuous axial slot 6 opens up the possibility of making the sleeve insert 1 by a winding process of a metal sheet and thus relatively inexpensive.
  • the flange portion 4 may also be formed of a different material, in particular of a softer material, than the shaft portion 3 and thereby in turn facilitate the forming of the flange portion 4. In this case, one speaks of a material weakening 5.
  • the individual materials of the shank portion 3 and the flange portion 4 can be glued to the finished sleeve insert 1 with each other, welded, caulked or otherwise connected.
  • the sleeve insert 1 is integrally formed and even in one piece and has only at the upper end of the bendable flange 4, whereas he already bent at the lower end before the actual installation or produced flange portion 4 'has.
  • the sleeve insert 1 is additionally stiffened by beads 7 in the region of the transition from the flange section 4 'to the shaft section 3.
  • FIGS. 2a and 2b it can be seen that it is formed from an inner sleeve 8 and an outer sleeve 9 arranged coaxially thereto, the material and / or cross-sectional weakening 5 being provided only on the inner sleeve 8 ,
  • the Fig 2a shows the sleeve insert 1 prior to installation in the plastic component 2
  • FIG. 2b shows the finished molded sleeve insert 1.
  • the sleeve insert 1 may be composed of several parts, as shown in the right-hand sectional view according to FIG. 3, the sleeve insert 1 in this case being formed from two sleeve sections 10 and 11 and a spring 12 arranged therebetween is, which spans the two sleeve sections in the axial direction 13 from each other.
  • the sleeve insert 1 in particular on one of the flange sections 4 on a material and / or cross-sectional weakening 5, which facilitates a folding of the flange portion 4.
  • a sleeve insert 1 composed of several parts is shown, wherein the two flange sections 4 can be made of a different material than the shaft section 3.
  • the deformed flange section 4 can in particular be made of a softer and thus more easily reshaped material be formed, this softer material represents the actual material weakening.
  • FIG. 4 it can be seen how the sleeve insert 1 according to the invention is installed in the plastic component 2.
  • the sleeve insert 1 with undeformed flange portion 4 and deformed flange portion 4 ' is inserted into a corresponding recess on the plastic component 2.
  • the flange portion 4 is deformed by a punch 14 and thereby the sleeve insert 1 minimizes tolerance in the plastic construction.
  • Part 2 fixed.
  • a counter punch 15 is provided, which supports the sleeve insert 1 via its flange section 4 '.
  • the sleeve insert 1 With the sleeve insert 1 according to the invention, a significantly improved tolerance compensation over conventional sleeves can be achieved, since the sleeve insert 1 is formed in the plastic component 2 and thereby applied directly thereto. About the relatively simple manufacturing process in which the curl, that is, the bending of the flange 4 takes place only in the plastic component 2, there are also cost advantages. In the case of a two-part or multi-part construction of the sleeve insert 1, a wide variety of materials can furthermore be used, as a result of which individual adaptation and optimization to the particular requirement is possible.
