Definitions

  • the invention relates to a method and an apparatus for producing metal foam composite bodies.
  • the invention further relates to a metal foam composite, in particular a composite plate.
  • Metal foam composites have gained great popularity as sandwich panels because of their high structural strength and low specific gravity, the cover sheets being made of aluminum panels with an aluminum-based metal foam core (AFS) or with steel facing sheets with an aluminum-based (SAS) metal foam core.
  • AFS aluminum-based metal foam core
  • SAS steel facing sheets with an aluminum-based (SAS) metal foam core.
  • Mainly metal foam composite panels are distinguished as AFS (aluminum-aluminum foam-aluminum sandwiches) and SAS (steel-aluminum foam-steel sandwiches with metallic bond).
  • Such composite elements are produced as metallurgically integral bodies and metal lightweight products without additives, such as adhesives, rivets or screws, so that these metal foam composite bodies also have a high aesthetic appeal.
  • an aluminum metal powder with a blowing agent e.g. TiH2 mixed and then compacted by means of a plunger in an axial compression molding step.
  • a cylindrical block of the powder metallurgy foam material is pressed through a die to form a foamable molding material.
  • the molding material is placed for foaming in a mold or in the profession2020ende component and foamed after heating the foam mold or the component with the foam material (Al-foam body elements) the component. After the desired formation of the metal foam, the component is cooled.
  • a method for producing a metal foam composite body using a roll-compacted container as a blank is known from EP 1 423 222 B1
  • a relatively complicated process for the formation of the blank under filling a premixed Metal / propellant powder in a container precompression of the powder and evacuation of the container after the gas-tight closure are required.
  • this manufacturing method for a composite blank on the one hand a foamable core material of metal or metal alloy and blowing agent and on the other hand has the cover layers formed from the upper and lower walls of the container, however, is relatively expensive.
  • the invention is therefore based on the object to provide a method and apparatus for producing metal foam composite bodies, which can be compared to the prior art by a significant simplification in terms of process management and thus execute in terms of manufacturing costs.
  • the invention is also based on the object to provide a correspondingly producible metal foam composite body.
  • the invention is characterized in that in a prepared metal container whose upper and lower walls form the later outer layers of the finished metal foam composite body, the foamable material, ie the material of metal or a metal alloy and a blowing agent, in particular aluminum or an aluminum alloy and blowing agent (TiH 2 ) are already inserted as pressed pressed semi-finished products. Subsequently, the container thus filled is sealed on all sides and highly compressed in a forming, preferably rolling, with substantial reduction in thickness and in this way without vacuum or gas guiding processes or the processing of metal ormaschineschpulvermischungen a blank made of composite material, consisting of the foamable pressed semi-finished material and the cover layers in a high density composite. This blank is subjected to a subsequent furnace process for foaming the interior space formed between the cover layers and filled with the pressed semifinished product of foamable material to form a sandwich metal foam composite body, preferably with a closed-cell foam body.
  • the foamable material ie the material of metal or a metal alloy and a
  • Such sandwich foam sheets are much easier and high damping capacity as lightweight panels of z.
  • the pressed semi-finished products are inserted as rods, rods or as plate-shaped elements in intersecting layers or as a small body or granules in the interior of the container, so that the interior of the container is filled almost completely, before the container z. B. is completely closed by welding or otherwise, and is subjected to a forming process, in particular rolling process for the production of the compacted blank.

  • the Fertig elaboratebearbeitung in terms of z. B. a plate size of the sandwich panels before the furnace process under a release treatment of the blank.
  • the covering material required in each case for the production of the respective foamed metal foam composite determines the production of a parallelepiped-shaped, in particular plate-shaped, container Blank for the production of the sandwich plate as provided here embodiment of the metal foam composite body forms.
  • the cover layer materials 1, 2 of the container 100 thus form the future cover layer plates of the prefabricated component and these are usually aluminum or an aluminum alloy or steel, which are connected via end and side plates 3, 4 to a container, preferably welded.
  • the container 100 (see Fig.1 ) is formed as an open container and it is in this the foamable material for forming the foam core as a pressed semi-finished aluminum-based 6, generally an aluminum-magnesium-silicon alloy, in which the blowing agent (generally TiH 2 is included integrated inserted.
  • the blowing agent generally TiH 2 is included integrated inserted.
  • the pressed semi-finished products 6 are preferably formed in the form of rods or rods with preferably rectangular cross-section (see. FIG. 4 ), which are stacked crosswise, ie in intersecting layers in the opening of the container 100. Then, container 100 is closed by the upper cover plate 1, ie, the upper container wall, this state as a graphical representation in FIG. 4 is shown. Preferably, the container 100 is tightly welded. To the air contained within the container 100 and the structure of pressed semi-finished material rods 6 of preferably rectangular cross section (see. FIG. 6 ) in connection with the subsequent high-grade compression of the container 100 by a subsequent forming process to allow the outflow, vent holes 5 are provided in a preferably in both end walls 3 or on the longitudinal sides of the container 100.
