  • the present invention relates to a method for soldering an arrangement which contains a honeycomb body arranged in a tubular casing.
  • Honeycomb bodies which are produced by stacking and / or winding sheet metal layers, at least some of which are structured sheet metal layers, are known in various forms. Such honeycomb bodies are used, for example, as carrier bodies for catalytically active coatings. Honeycomb bodies coated in this way are used, for example, as catalyst support bodies. In particular for internal combustion engines, such as those used in motor vehicles, the honeycomb bodies with the casing tube form part of an exhaust system. Different configurations of an arrangement as a catalyst carrier body are described, for example, in EP-A1-0 245 738.
  • the stacked and / or wound sheet metal layers are at least partially soldered to one another, so that a monolithic honeycomb body is formed. It is known that the honeycomb body is at least partially soldered to a jacket tube in which it is arranged. For this purpose, solder is introduced into the soldering areas of the sheet metal layers and the jacket tube.
  • Methods for applying an adhesive and soldering a metallic arrangement containing a honeycomb body and a jacket tube are known, for example, from WO 89/11938, WO 94/06594, WO 93/25339 and DE-29 24 592 AI.

  • EP 0 474 909 A1 discloses a method for soldering an arrangement in which a honeycomb body is brought into contact with an adhesive carrier with one end face. The adhesive should be sucked into the channels due to capillary action.
  • DE 29 24 592 AI discloses a method for connecting a honeycomb body to the jacket tube, in which the honeycomb body with the jacket tube is immersed in an immersion bath containing an adhesive liquid and then provided with powdered solder.
  • the present invention is based on the objective of specifying a method for soldering an arrangement which enables a uniform introduction of an adhesive into the honeycomb body.
  • a honeycomb body is first formed by stacking or winding sheet metal layers, at least some of which are structured sheet metal layers, in such a way that it has channels for a fluid to flow through.
  • the honeycomb body is placed in a jacket tube.
  • At least one end face of the honeycomb body is brought into contact with a roller containing an adhesive, which can be rotated about a roller axis.
  • the honeycomb body and the roller are moved relative to one another in such a way that the roller rolls on at least part of the end face of the honeycomb body and releases an adhesive to the honeycomb body during the rolling process.
  • a solder is at least introduced into the honeycomb body.
  • a uniform application of an adhesive to or into the honeycomb body is achieved by the process according to the invention.
  • Possible unevenness in the end face of the honeycomb body which results from an offset between sheet metal layers of the honeycomb body, does not impair the application of the adhesive.
  • the fact that the roller rolls on the end face also reduces the wear on the roller, since the same places on the roller do not always come into contact with the relatively thin flanges of the sheet metal layers. This also extends the life of a device that is suitable for carrying out the method.
  • the honeycomb body and the roller can be moved to apply the adhesive.
  • a rapid application of an adhesive is achieved if the roller and the honeycomb body are moved in a translatory manner in the opposite direction.

  • the honeycomb body around its longitudinal axis and the roller which has a shape adapted to the end region, and extend radially inward only up to the longitudinal axis extends, do a roller axis intersecting the longitudinal axis at an angle of about 90 °. With this procedure, the roller is brought into contact with the surface of the projecting end region.

  • a diffuser can be provided on the one connecting area of the mante ear, which is connected, for example, to an exhaust line of an exhaust system of an internal combustion engine.
  • the jacket tube has two connection areas which are formed at the respective end of the mante ear, wherein there is essentially no honeycomb body in these connection areas.

  • the portion of the honeycomb body protruding from the mante ear is brought into contact at the end with the roller containing an adhesive.
  • the honeycomb body is then introduced into the mante ear and a solder is introduced into the honeycomb body.
  • the jacket tube is not provided with an adhesive, it is also not necessary to free this jacket tube from the adhesive in order to prevent the adhesive from being carried over.
  • the honeycomb body is at least partially provided with the adhesive in its axial direction, it is also achieved that the honeycomb body is provided with the adhesive over its entire cross-sectional area, so that even edge areas of the honeycomb body can be properly provided with a solder powder. This ensures that a reliable soldered connection can also be formed in the edge region of the honeycomb body or between the honeycomb body and the mante ear.
  • a portion of the honeycomb body opposite the portion is brought into contact with an adhesive before the solder is introduced.
  • honeycomb body be pushed through the mante ear so that a section protrudes from the mante ear. This section is brought into contact with the adhesive. The honeycomb body is then introduced into the mante ear in such a way that the honeycomb body does not essentially lie in the connection areas of the casing tube.
  • the honeycomb body be introduced into the mante ear so that it is brought into contact with the adhesive during one or the other section over a substantial part of its axial length in the mante ear.
  • the arrangement has a conveniently located spot which prevents the arrangement from tipping over.
  • the honeycomb body be introduced into the tubular casing so that it protrudes at least 1 mm, preferably 5 mm, from the tubular casing. This extension is sufficient to prevent the jacket tube from coming into contact with the adhesive.
  • the honeycomb body and the jacket tube have different thermal expansion behavior.
  • the aim is therefore to avoid a rigid connection between the honeycomb body and the casing tube in the respective end regions of the honeycomb body. If there are no rigid connections in the respective end regions of the honeycomb body with the mante ear, thermal stresses between the mante ear and the honeycomb body are avoided. From WO 96/26805 it is already known how such thermal stresses can be avoided by suitable soldering of the honeycomb body to the tubular casing.
  • Thermal stresses between the honeycomb body and the mante ear are avoided by introducing a sleeve-shaped element into the mante ear, which has an outer jacket which essentially comes to rest on part of the inner jacket surface of the mante ear, and in which the honeycomb body is arranged.
  • This socket-shaped element prevents the honeycomb body from being soldered to the jacket tube.
  • the bush-shaped element extends only over part of the axial extent of the mante ear and the honeycomb body.
  • the sleeve-shaped element is preferably formed by a film.
  • a mante ear has a certain out-of-roundness due to manufacturing technology. There are also tolerances regarding the fluctuations of an inner diameter of the mante ear. As a result, a gap is formed between the inner circumferential surface of the casing tube and the element. Because the honeycomb body is brought into contact with an adhesive from the jacket tube above, the adhesive is prevented from getting into the gap between the element and the jacket tube, so that this gap also remains essentially solder-free after application of a solder. This also ensures that there is no solder connection between the jacket tube and the socket-shaped element. On the other hand, it is achieved that the honeycomb body can be soldered to the socket-shaped element and also to the socket-shaped element.
  • the sleeve-shaped element is connected to the jacket tube, so that when the honeycomb body is introduced into the mante ear, the sleeve-shaped element maintains a predetermined position, although the honeycomb body, which is pressed in the axial direction of the mante ear and thus also the sleeve-shaped element, and thereby exerts a force exerts the sleeve-shaped element in the direction of insertion of the honeycomb body.

  • this can be removed during a soldering process due to the temperatures prevailing during the soldering process.
  • the fact that the connection between the element and the mante ear has a lower strength than the connection between the element and the honeycomb body also ensures that thermal stresses between the mante ear and the honeycomb body are not introduced via the element into the honeycomb body.
