Definitions

  • the invention relates to a solid rivet and in particular, but not exclusively a solid rivet for the joining of composite components according to the preamble of claim 1.
  • the majority of solid rivets currently in use are made of aluminum alloys (2017-T42, 21 17-T42 and 7050-T73), for special applications full rivets made of titanium or titanium alloys are used. Full rivets made of steel are no longer used in aircraft construction.
  • bi-metallic rivets e.g. from the company Cherry. This rivet consists of a shaft made of a high-strength titanium alloy (Ti6AI4V) and a shaft end of a soft titanium alloy (Ti45Nb). Both components are connected by friction welding during the manufacture of the rivet.
  • the installation of the rivet is done by forming the soft shaft end.
  • these connecting elements are also suitable for joining components made of fiber-reinforced plastics (FRP), ie to form FRP / FRP structures.
  • FRP fiber-reinforced plastics
  • solid aluminum rivets can not be used, instead a titanium alloy (TiNb45) is used as the rivet material.
  • An anchoring rivet is known from US Pat. No. 2,358,728, in which a shaft comprises a stepped head, a pin with a smaller diameter that adjoins the shaft, a groove extending transversely to the shaft directly next to the pin, and an additional slot for receiving material.
  • a method of making a riveted joint is known in which a rivet is used with one or more annular grooves in the shank of the rivet.
  • the groove serves to retard the transition of the rivet into a mushroom shape thereby shortening the central portion of the rivet so that the material is forced substantially evenly outwardly.
  • Object of the present invention is to provide a rivet, with which the mentioned disadvantages can be avoided and which allows a firm and reliable connection of FRP components with each other, without this means an increased manufacturing cost.
  • An essential aspect of the invention is that in the solid rivet according to the prior art, a recess, a groove or bevel is provided in the shaft of the solid rivet, which is located at the level of the back of the closing head side material. While the FVK component delaminates from the bore edge during the installation of a conventional solid rivet without such a recess or chamfer, the chamfer in the solid rivet according to the invention prevents contact of the rivet at the bore edge with the component to be joined, so that delamination of the FVK component is prevented. Component is avoided in this area.
  • the solid rivet according to the invention with a setting head and a shaft, which is aligned axially with the setting head, wherein the maximum diameter of the setting head is greater than the outer diameter of the shaft, characterized in that the shaft has at least one end portion, an intermediate portion and a head portion, wherein the outer diameter of the intermediate portion is smaller than the outer diameter of the end portion.
  • the solid rivet according to the invention has as one or - as far as is technically possible and reasonable - as several features that:
  • the end portion tapers, wherein it has a smaller outer diameter at its free end;
  • the end portion is made of a soft material and the intermediate portion and / or the head portion is made of a high-strength material;
  • the end portion tapers, wherein it has a smaller outer diameter at its free end;
  • the transition between the head section and the intermediate section and / or between the intermediate section and the end section is step-shaped
  • the transition between the head section and the intermediate section and / or between the intermediate section and the end section has only one edge
  • the difference between the diameters of the head portion and the intermediate portion is dependent on the length of the intermediate portion
  • the rivet according to the invention offers i.a. the following advantages: it is installed just like the "classic" rivet, i.
  • the known tools can be used and the joining of components with the solid rivet according to the invention can be carried out in exactly the same way as in the prior art. Furthermore, you can achieve a weight savings through a correspondingly deep chamfer or groove.
  • Fig. 1 shows a solid rivet according to the prior art before deformation.
  • Fig. 2 shows the solid rivet according to Fig. 1 after deformation.
  • FIG 3 shows an embodiment of the solid rivet according to the invention before deformation.
  • FIG. 4 shows the solid rivet according to FIG. 3 after the deformation.
  • FIGS. 5 to 8 show further preferred embodiments of the solid rivet according to the invention.
  • Fig. 1 shows a solid rivet according to the prior art, with which an upper component 1 and a lower component 2 are to be connected, of which only one section is shown.
  • a bore 3 is provided, which extends through both components.
  • a solid rivet 4 is inserted, where it is prevented on the one hand by a setting head 5 from slipping completely through the hole 3.
  • a shaft 6 connects, which is aligned axially with the setting head 5 and is so long that it projects beyond the setting head 5 opposite side of the bore 3.
  • the setting head can preferably be sunk in the surface of the upper component 1, so that it is flush with the surface of the component 1. Its maximum diameter is greater than the inner diameter of the bore 3 and larger than the outer diameter of the shaft 6.
  • the component 2 when the shaft 6 is deformed at its free end to the closing head 7, the component 2 may be impaired.
  • the strength of the laminate structure of the component 2 is impaired.
  • it can also lead to a depression of the component 2 in the vicinity of the bore 3, as indicated by the dashed lines in Fig. 2, which show the original thickness of the component or its ideal state after joining.
  • the solid rivet 4 is provided with a chamfer or groove at the level of the outlet edge of the bore 3.
  • a first embodiment of such a solid rivet according to the invention is shown in FIG.
  • the uniform shaft 6 is replaced by three different sections.
  • the head 5 is followed by a head section 9.
  • This is followed in the direction of the free end of the solid rivet, an intermediate portion 10, and this in turn is followed by an end portion 1 1, which forms the free end of the solid rivet 4.
  • the individual sections are marked or differ from each other in that they all have a different diameter from the respectively adjacent section.
  • the outer diameter of the intermediate portion 10 is smaller than the outer diameter of the end portion 1 1.
  • the outer diameter of the intermediate portion 10 is smaller than the outer diameter of the head portion 9.
  • the relationship of the diameter of the head portion 9 and end portion 11 is arbitrary.
  • the head portion 9 may have a larger diameter than the end portion 11, as indicated in Fig. 3, but it is also possible to choose the diameter of the end portion 11 is equal to or slightly larger than that of the head portion 9 (not shown ).
  • the diameter of the intermediate portion 10 is indicated in Fig. 3 with "a".
  • the three sections 9, 10 and 1 1 are shown in Fig. 3 and Fig. 4 are each cylindrical. However, this is not a requirement for the solid rivet according to the invention.
  • the intermediate section 10 only has a smaller diameter in regions than its adjacent sections 9 and 11.
  • its cross-sectional shape in the direction of the axis of symmetry shown in dashed lines in FIGS. 1 to 4 would thus not be circular, but for example elliptical or rectangular with rounded corners or a circle with two opposite flattenings etc.
  • FIGS. 5 to 8 Further modifications of the solid rivet according to the invention are shown in FIGS. 5 to 8.
  • Fig. 5 the embodiment of FIG. 3 is shown again.
  • the feature of the solid rivet, which varies in Figs. 5 and 6, is the transition between the individual sections.
  • the transition between the sections is step-shaped, ie there are two edges between the intermediate section 10 and the head section 9 and between the intermediate section 10 and the end section 1 1.
  • the embodiment according to FIG. 5 differs from the embodiment according to FIG 6 in that the transition between the head portion 9 and the intermediate portion 10 and between the intermediate portion 10 and the end portion 1 1 is rounded, so that each transition has only one edge.
  • This embodiment is easier to realize in terms of manufacturing technology, since a groove is produced here only with a simple tool must be, while in the embodiment of Fig. 5, the diameter of the intermediate portion 10 must be reduced by milling.
  • the introduction of the chamfer can thus be done by machining (for example by turning) or introduced by forming. Both processes can be carried out by the rivet manufacturer or even by the riveting user.
  • FIG. 7 Another embodiment of the solid rivet according to the invention is shown in FIG.
  • the end portion 11 tapers to have a smaller outer diameter at its free end.
  • his handle when setting in the hole 3 is easier.
  • the embodiment of the solid rivet 4 according to FIG. 7 differs from the preceding embodiments in that its intermediate section 10 is extended.
  • the choice of the dimension of the intermediate section 10 (and also of the other sections) in the axial direction depends essentially on the strength requirements of the respective section and with the diameter "a" of the intermediate section 10 together.
  • FIG. 8 an embodiment is shown in Fig. 8, which has a plurality of intermediate portions and end portions: in addition to the first intermediate portion 10, a second intermediate portion 12 is provided, which adjoins the first end portion 11. This embodiment is completed by a second end portion 13. This embodiment is particularly useful when different components 1 and 2 are to be assembled with a rivet of different thickness, but on the other hand not different rivets are to be kept in stock.
  • the respective materials can also be selected such that they are optimally suited for the particular application of the solid rivet 4.
  • the solid rivet does not have to be monolithically made of a material but, for example, the end portion 11 may be made of a soft material and the intermediate portion 10 or the head portion 9 may be made of a high strength material. In this way it is achieved that the end portion 1 1 absorbs a large part of the deformation work and is reduced in length while increasing its width. Examples of materials are the high strength Ti6AI4V and the softer Ti45Nb. references
