Definitions

  • cavity structures have a high degree of rigidity with little Have weight.
  • the adjacent cavities form a braced one Structure that supports and stiffens the whole body.
  • foaming e.g. aluminum foam, polystyrene, .
  • the German patent application DE 101 01 059 A1 discloses a plate with regular Projections and a method and an apparatus for their formation.
  • the one described Plate is used in particular as a separator for a fuel cell.
  • Two such Plates are placed between two cell units.
  • the trained on both plates Projections abut each other in such a way that there is a flow-through cavity between the plates is trained.
  • the function of the plates is defined on the one hand by the production of a Distance, on the other hand characterized by the provision of this cavity.
  • a connection of the plates, which could cause a supporting and stiffening bracing, is not described.
  • the invention has for its object another method of manufacture and construction Design of similar cavity structures made of metal, plastic or paper ready for put.
  • up and down humps becomes a flat braced Shaped component generated, the polygonal surfaces lying parallel to each other on at least three levels having.
  • the polygonal areas on the outer levels form the high and low areas the cusps trained up and down. Between these humps on the further polygonal surfaces are arranged in the middle level.
  • the corresponding surfaces become another attached molded component on the associated surfaces of the underlying molded component set.
  • the bumps of a molded component join the bumps of a molded component with the humps of another superimposed interlocking manufactured in the same way Molded component either on the side surfaces of the humps and / or on the corresponding Polygonal surfaces form-fit to one another.
  • Molded component either on the side surfaces of the humps and / or on the corresponding Polygonal surfaces form-fit to one another. Will these contact surfaces for connecting of the molded components, a rigid overall construction is created.
  • the polygons consist of 6 corners and both the polygons as also corresponding side surfaces of the humps of molded components placed one inside the other abutting each other, a closed cube-like cavity structure is created, the Do not communicate single cavities.
  • Each molded component is half of the cube-like cavities ready by the next molded component with the second half are provided and thus form closed cavities.
  • the hexagonal to triangular polygonal surfaces can also be used with each other communicating cavities are created where the corresponding side surfaces the hump of two molded components are in contact and the polygonal surfaces are at a distance thus creating a passage between the cavities.
  • a spatial is created always the same cavity structure made up of nothing but cube-like or cuboid shapes, that share side walls with each other and are each offset by one level.
  • the one with more Molded side surfaces and polygonal surfaces form flat contact surfaces the interlocking molded components.
  • the corresponding ones Side faces of the hexagon bumps (cube-like half-bodies) of several interlocking Set molded components form struts of a double that run diagonally in 3 spatial directions Y-shape, which have a high buckling stiffness and are characterized by the entire composite Continue body.
  • cover plates that cover the outside Polygonal surfaces are connected, there is a crisscrossed and fanned out
  • the core of a sandwich that allows optimal thrust transmission.
  • the result is a tube-like one Cavity structure that is composed along and / or across the entire compound Molded component extends.
  • This structure can e.g. be used as a heat exchanger can flow through different media separately through a molded component.
  • the high and deep polygons with the same offset to the middle level.
  • Constructions are also feasible in which the high and low areas differ Distance from the middle level.
  • the cusp side surfaces and / or the polygonal surfaces Further molded components are then produced in the same way with the corresponding one Counter mold component in contact when the other mold components are rotated by 180 degrees and can be used interlocking.
  • spatially braced flat shaped components can be produced, their polygonal surfaces are arranged on more than 3 levels.
  • the middle level and the Polygonal surfaces arranged on the upper level in turn with one another again and again regularity evenly offset (now a total of 7 levels) is the accuracy of fit interlocking molded component further guaranteed.
  • the polygon areas are on at least three levels and the cusps are the same regular recurring shape, so that more interlocking Molded components used on the corresponding side surfaces and / or the polygonal surfaces lie flat in contact with each other.
  • Deep-drawn sheet metal is used as the material for the spatially braced flat molded component
  • Metal, deep-drawn plastic, cellulose and fiber-reinforced materials (laminates and Injection molding material) can be used.
  • the molded components can be manufactured using dies, between which the sheets or plastics are deep-drawn, the laminates inserted or that Injection molding material introduced and can harden.
  • Made of GRP [glass fiber reinforced plastic] and CFRP [carbon fiber reinforced plastic] manufactured molded parts also offer the possibility of additionally reinforcing highly stressed zones with inserted rovings.
  • connection of several molded parts happens, depending on the application and requirement profile, through gluing, soldering, welding and various riveting techniques.
  • the areas of application extend to a wide area where lightweight construction and high rigidity are required.
  • a large area of application is also seen in the packaging industry, because the goods to be packaged are protected from slipping on all sides by walls can.
  • the variant with the closed cube-like cavities can e.g. as a crash element be used.
  • the energy introduced is then partially deformed of the cube structures, but also partly implemented in the resilient air cushion.
