Definitions

  • the present invention relates to a method and devices for producing a metal sheet with a corrugation which has a first predetermined corrugation height, the sheet metal having a microstructure with a second, substantially smaller corrugation height transversely or at an angle to the corrugation.
  • Such metal sheets are mainly processed into honeycomb bodies for catalytic converters, such as those used in particular in exhaust systems of motor vehicles.
  • the invention is not limited to this application, since z. B. Applications in heat exchangers are possible.
  • a microstructure in a corrugated sheet is understood to mean a structure which has a significantly lower height than the corrugation of the sheet.
  • a microstructure can protrude from a sheet on one or both sides, for example by at least 15 ⁇ or by 0.01 to about 0.3 times the corrugation height of the metal sheet.
  • Corrugated metal sheets are generally produced in the prior art by corrugating rollers which mesh with one another and which preferably have an involute toothing or a similarly shaped toothing.
  • other corrugated shapes for example trapezoidal shape, zigzag shape, etc., are also known.
  • TS design transverse structures
  • the prior art therefore provides for microstructures to be arranged one behind the other at specific intervals in the direction of flow, in particular at intervals of less than 20 mm, in particular less than 10 mm.
  • microstructures were relatively small in relation to the typical thickness of sheets for honeycomb bodies, it had previously been assumed that they would not significantly interfere with the further manufacturing process, so that processing was carried out in the usual corrugated rolls and further with known manufacturing steps for forming a honeycomb body .
  • the object of the present invention is therefore to create a production method and a corresponding device with which corrugated metal sheets with microstructures that run diagonally or diagonally to the corrugation can be produced economically and without undue cold deformation.
  • a device according to claim 1 and a method according to claim 9 serve to achieve this object.
  • Advantageous embodiments are specified in the respective dependent claims.
  • the device according to the invention for producing a metal sheet with a corrugation which has a first predetermined corrugation height, the sheet metal having a microstructure with a second, substantially smaller corrugation height transversely or at an angle to the corrugation contains a device for producing the microstructure, a pair intermeshing corrugated rollers which are arranged behind the device for producing the microstructure, the corrugated rollers having recesses on their outer surfaces which are suitably arranged and / or are large enough to accommodate the microstructures so that the microstructures are not of corrugation with the metal sheet the corrugated rollers are deformed.
  • Corrugated rollers with a type of involute toothing are typically used, but the invention is not restricted to this type of roller.
  • all types of corrugated rolls have a certain ses game to each other, which means that it is difficult to reproduce distances on the flanks and / or on the tips of the teeth or in the spaces between the teeth during the production process.
  • this play has no influence whatsoever on the height of the microstructures.
  • the device for generating the microstructure and the corrugated rollers can be adjusted relative to one another in such a way that the generated microstructures always meet in recesses in the corrugated rollers.
  • the easiest way to achieve this is by a very close spatial arrangement, but it can also be achieved by suitable adjustment devices at larger distances.
  • honeycomb bodies are formed from alternating layers of smooth and corrugated metal sheets or from alternating layers of differently corrugated metal sheets, various designs being known, for example sheet metal layers that are spirally wound, S-shaped or entangled in the manner of an involute.
  • a special embodiment of the device according to the invention provides that at least one smoothing device is arranged downstream of the corrugated rollers, which can flatten the microstructures on the corrugated peaks of the corrugated sheet on one side or on both sides.
  • Such a device can be, for example, a corrugated roller with cutouts that runs against a flat roller.
  • microstructures on the wave crests are flattened where they would have no influence on the flow that later flows in the honeycomb body, which considerably simplifies the connection by means of solder.
  • the other microstructures remain unchanged and can perform their intended function without further disruption to the production process.
  • corrugated rollers instead of corrugated rollers and the smoothing device arranged behind them, which have no recesses in their troughs, so that the microstructures can be flattened there. This can be achieved particularly well if the corrugated rollers have only a slight play between opposite troughs and wave crests.
  • the method according to the invention for producing a metal sheet with a corrugation and a microstructure has the following steps:
  • Fig. 1 shows schematically a corrugated device according to the invention and Fig. 2 schematically shows the production process according to the invention
  • FIG. 1 the heart of the present invention, namely a shaft device for sheet metal is shown.
  • a metal sheet 1 which has already been provided in a device for producing microstructures with downward facing microstructures 6 and with upward facing microstructures 7, is fed to a pair of corrugated rollers 3a, 3b.
  • These corrugated rollers have cutouts 8 on their surface, which are in particular in the form of grooves. These cutouts 8, of which only one is shown in the drawing, accommodate the previously created microstructures 6, 7, so that they are not influenced by the corrugation process when the sheet is corrugated.
  • the height of the microstructures 6, 7 is significantly smaller than the first corrugation height A of the corrugated metal sheet 1.
  • the metal sheet 1 runs initially by means 2a, 2b for generating the microstructure, as is known from the prior art.
  • it can be cylindrical rollers with corresponding surface structures or individual narrow disks which are brought together and which apply the microstructure to the metal sheet 1 by cold working.
  • This is then fed to a pair of corrugated rollers 3a, 3b, as shown in more detail in FIG. 1.
  • the microstructures on the wave crests 9, 10 of the corrugated metal sheet 1 are undesirable, they can be smoothed by smoothing devices 4a, 4b or 5a, 5b.
  • Such smoothing devices consist, for example, of a cylindrical roller 4a or 5b with a smooth surface, which runs against a corrugated roller 4b or 5a, these corrugated rollers preferably having the same cutouts as those used to produce the corrugation.
  • Corrugated metal sheets produced in this way and provided with microstructures can be used in particular for honeycomb bodies in exhaust systems. They increase the heat transfer between the honeycomb body and a fluid flowing through and accelerate diffusion processes, which is particularly advantageous for the effectiveness of a catalytic converter.
