Definitions

  • the present invention relates to a method of tying two or more components together according to the preamble of claim 1.
  • Such a method can be used for the manufacture of a number of products, but it will hereafter be described by way of example in no way restrictive of the invention how the method can be applied in order to tie a number of components together, so that these form a cohesive and self-supporting construction with a view to joining the components together, for example by soldering, at a subsequent stage of manufacture.
  • soldering In the aircraft industry, for example, there is a need to join various components, such as plates, together by soldering or some other method of joining, for the manufacture of various constructions. In order to facilitate the soldering of a number of plates these must be fixed in relation to one another during the soldering phase. A fixture or a so-called soldering jig can be used for this purpose. If the construction comprises a large number of components, however, or if it has a complex geometry, this will place great demands on the design of the soldering jig. In addition to the fact that the complexity of the soldering jig leads to high production costs, it will also be difficult to handle at the soldering stage.
  • One way of dispensing with the use of a soldering jig is instead to preassemble the plates into a self-supporting construction prior to soldering. Such preassembly can be achieved by welding or riveting the components together.
  • brittle materials such as intermetallic alloys, for example TiAl, NiAl and FeAl
  • conventional welding and riveting can have an adverse effect on the material and on the characteristics of the finished product, due to the occurrence of cracking.
  • US 2,909,651 discloses a method using heat and pressure for the forming of metal elements, particularly the heading of titanium rivets. The method utilizes squeeze pressure and requires heating of the metal to working temperature in conjunction therewith.
  • the object of the present invention is to provide a method of the type defined in the introductory part, in which method at least one of the aforementioned disadvantages of such hitherto known methods is substantially mitigated, that is to say to provide a method of tying components together by means of a fastener, by which method even particularly brittle materials can be tied together without unduly adverse effects on the material in the form of cracking or the formation of undesirable brittle phases in the material.
  • this object is achieved by a method according to claim 1.
  • the fastener is essentially heated only during the deformation phase of the fastener. This minimizes the heat transfer from the fastener to the components that are to be tied together. Heat only has to be supplied to the fastener and only to the extent needed to deform the fastener to the required degree under the relevant load. This in turn means that the components can be kept at a relatively low temperature without large temperature gradients and that the characteristics of the material of the components can remain largely unaffected during tying. In this way it is also possible to make efficient use of the quantity of energy used for tying purposes.
  • a major advantage of the method according to the invention is that it is possible to use non-preheated components and non-preheated fasteners.
  • the components and the fastener Prior to tying, may be at ambient temperature, such as normal room temperature, or a temperature close to this. This makes it possible to dispense with costly processes and devices for the heat treatment of components prior to and/or after tying, whilst tying can be carried out without significant adverse effects on the components.
  • the fastener is first pressure-loaded and the fastener then heated whilst maintaining the pressure loading.
  • the initiation of the fastener deformation sequence can be controlled with the supply of heat to the fastener, the heat being suitably obtained by passing an electrical current through the fastener.
  • the use of electrical current for transferring heat to the fastener has the advantage that it is relatively easy to control, that is to say the current strength and the time for which the current must flow through the fastener can be adjusted to the relevant material and dimensional parameters in order to produce the required heat transfer.
  • the fastener is pressure-loaded by means of a tool and after deformation of the fastener the mechanical contact between the pressure loading tool and the fastener is maintained to allow cooling of the fastener through the transfer of heat from the fastener to the pressure loading tool.
  • the excess heat present in the deformed fastener can thereby largely be absorbed by the pressure loading tool, which can be cooled in order to promote.such heat transfer, and the undesirable transfer of heat to the components being tied by the fastener can in this way be further reduced.
  • a suitable tool for carrying out the tying is a combined pressure loading and heating tool having two electrodes, between which the fastener is placed and by means of which electrodes a pressure can be applied to the fastener whilst heat can be delivered to the fastener by an electrical current flowing between the electrodes during the fastener deformation phase. Heat can furthermore be dissipated from the fastener following the deformation phase in that the electrodes have a lower temperature than the fastener.
  • Two or more components 1, 2 which are to be tied are provided with a through hole and the components 1, 2 are placed so that these holes overlap one another in order to receive a fastener 3 in the holes.
  • the fastener 3 has longitudinal extent exceeding the total thickness of the components 1, 2, so that a part 4 of the fastener protrudes outside the holes and the components and is thus exposed for deformation, that is for compressing towards the nearest component 1 with simultaneous expansion of the cross-section of this part 4 of the fastener 3.
  • the fastener 3 placed in the holes is pressure-loaded mechanically and heated in order to deform the fastener 3, thereby tying the components 1, 2 together.
  • the fastener 3 is heated essentially only during the fastener deformation phase in order to minimize the heat transfer from the fastener 3 to the components 1, 2 to be tied.
  • the expression "essentially only during the fastener deformation phase” is intended to signify that heat is not supplied before or after the deformation of the fastener in order to produce the tie.
  • the fastener 3 is therefore not preheated when placing this in the holes in the components and no preheating in the conventional sense occurs prior to the deformation phase, nor do the components 1, 2 need to be preheated.
  • a certain heat transfer to the fastener 3 may occur prior to deformation, owing to the fact that the deformation does not occur instantaneously when heat is supplied to the fastener, but a certain delay probably occurs between the supplying of heat and the deformation.
  • a certain heat supply may be present just after deformation, due to a possible hysteresis in the system. The aim, however, is to minimize heat transfer to the fastener 3 and hence to the components 1, 2 after deformation of the fastener has been carried out.
  • Fig. 1 shows how a rivet 3 for tying two plates 1, 2 together is loaded.
  • a load F which is sufficient to deform the rivet 3 in the hot state is applied to the fastener 3 by moving two electrodes 5, 6 in a combined pressure loading and heating tool 7 in a straight line relative to one another and towards one another with the rivet 3 arranged between the electrodes.
  • One of the electrodes 5 can be suitably fixed and accommodate a headed end 8 of the rivet 3, for example, whilst the other electrode 6 is designed for rectilinear movement towards (and away from) the other end 9 of the rivet and the first electrode 5.
  • both electrodes 5, 6 may be designed for rectilinear movement.
  • Fig. 2 shows how in a subsequent stage, by means of a voltage source 15, an electrical voltage is applied over the electrodes 5, 6 and thereby over the rivet 3.
  • the current strength and the duration of the current are naturally adjusted to the different conditions prevailing during the actual riveting operation, such as the dimensions and material of the rivet 3, which in turn depend on the material and dimensions of the plates 1, 2.
  • the duration of the current often ranges from fractions of a second up to about one second.
  • the voltage source 15 it is possible to use both an alternating current voltage source and a direct current voltage source in order to generate the required current.
  • the load on the rivet 3 can be maintained, or at least the mechanical contact between the electrodes 5, 6 and rivet 3 can be maintained even if the load F is reduced or removed, in order to cool the rivet 3 by means of the electrodes 5, 6, that is to say in order that any excess heat in the rivet 3 will be transferred to the electrodes rather than to the plates 1, 2. It is advantageous, however, in order to prevent cracking, that the load be maintained during the cooling process. Such cooling of the rivet 3 is typically completed in one to a few seconds. In order to facilitate the transfer of heat from the rivet 3 to the pressure loading tool 7 after deformation of the rivet 3, the pressure loading tool 7 can be cooled by means of conventional equipment.
  • the method, or at least the heating of the fastener 3, is suitably performed in an atmosphere containing an inert gas, in order to minimize oxidation of the fastener 3 and/or the components 1, 2, which in practice to some extent probably also involves placing the components 1, 2 to be tied in such an atmosphere.
  • the electrodes 5, 6 and the components 1, 2 can be moved in relation to one another in order, where required, to permit riveting in another position of the components 1, 2 using a further rivet.
  • a protective component 10 in the form of a rivet washer 10, for example.
  • the rivet washer 10 may be arranged round the rivet 3 at the deformation end 9 of the rivet up against one of the components 1. In this way, in subsequent deformation of the rivet 3 direct contact between the hot deformed material of the rivet and the plate 1 will be prevented, which means that the greatest temperature gradient will be between the rivet 3 and the rivet washer 10 rather than between the rivet 3 and the plate 1.
  • the fastener 3 illustrated in Fig. 1, 2 and 3 may be designed in a number of different ways without departing from the scope of the invention.
  • the fastener 3 in the example described above has an elongate section 11 with circular cross-section and a head 12 at one end 8
  • the head 12 might be eliminated even though this in turn requires more advanced riveting equipment in order to control the deformation of the rivet.
  • the rivet 3 be provided with a head, this may be designed both for flush riveting and raised riveting.
  • Three examples of different rivets 3a, 3b, 3c having different types of heads 12, 12b, 12c are illustrated in Fig. 4 , of which one rivet 3b is designed for flush riveting.
  • the piercing of holes in the components 1, 2, required for tying them together can be performed by conventional methods such as drilling, spark erosion or water cutting.
  • the shape and size of the holes and the shape and size of the rivet are matched to one another so that the desired riveted connection can be achieved by deformation of the rivet when this is placed in the holes.
  • Holes and rivets of circular cross-section with substantially the same diameter are preferably used, but it is also possible to use rivets of different cross-section.
  • Piercing can be performed simultaneously for the components to be tied, or separately for each component.
  • a layer of material such as a soldering foil (not shown) can be arranged between the components before or after piercing the holes. The soldering foil is then used for soldering the components together.
  • multiple rivets can be riveted essentially simultaneously through the use of more than one pressure loading tool or one pressure loading tool that can be applied to a number of rivets at a time, for example one tool having more than one pair of electrodes.
  • the method according to the invention is particularly well-suited to tying brittle materials together, such as intermetallic alloys, and rivets of a material from the group of intermetallic alloys are preferably used for this purpose.
  • alloys in the intermetallic alloys category are TiAl, NiAl and FeAl.
  • Experiments aimed at manufacturing products suitable for use in the aircraft industry using the method according to the invention have successfully been carried out.
  • the method has been applied to plates made of TiAl with a thickness of 1 mm. Rivets made of TiAl are used for tying the plates together and a soldering foil Ticuni 70 with a thickness of 50 ⁇ m for soldering the plates together after riveting.
