Definitions

  • a method for producing a structured material web from a sheet material, in particular sheet material web, in the planar and three-dimensional coarse structuring comprehensive and stiffening coarse structure elements and adjacent to the roughing at least a section with a fine structure elements comprehensive fine structuring are formed, wherein the fine structure elements are produced with dimensions that are smaller than dimensions of the coarse structure elements.
  • the structured material web has a fine structuring in at least one section adjacent to the coarse patterning.
  • the fine structuring has a somewhat less stiffening effect than the rough structuring.
  • the fine structures preferably have a structure depth, namely a clear structure height which corresponds approximately to the wall thickness of the material web to be joined, that is to say the material thickness without structure depth.
  • the fine structuring is preferably developed and technically adapted according to the laws of controlled self-organization. In this way, the material of the material web during structuring is only slightly plasticized and spared. The remaining plasticizing reserves can be used for secondary forming processes or / and they increase the fatigue strength in the later dynamic operating behavior (Wöhler curve) of the finished product.
  • An advantageous embodiment of the invention can provide that in the at least one section with the fine structuring a length shortening adapted to the roughing is formed.
  • a shortening of the length of the material web in the sections of the fine structuring is therefore advantageous because the material web is also shortened in length by the coarse patterning - d.
  • the at least one section includes a border section with the fine structuring.
  • a preferred embodiment of the invention provides that a transition structure is formed between the edge portion and the rough patterning.
  • the at least one section with the fine structuring comprise a transition section which is formed between sections with the coarse patterning.
  • An advantageous embodiment of the invention may provide that the at least one section with the fine structuring in the region transverse to a running direction comprises substantially flat sections formed. This is possible because during buckling or vault structuring process, the length shortening (gathering) across the production direction is considerably less than in the production direction. Further details will be described below.
  • the fine structuring is formed by means of one or more structural elements from the following group of structural elements: wave structure, leaking bead structure, wrinkle structure, rhombic structure, rhombic structure, rectangular shape, heart shape and hexagonal structure.
  • a preferred development of the invention provides that the fine structuring is connected to the coarse patterning via a bead.
  • the fine structuring is a self-organizing structuring.
  • Such structures are known, for example, in the form of a bulge / bulge structure with depressions and surrounding folds or as wave structures with calottes and surrounding beads.
  • An advantageous embodiment of the invention can provide that the at least one section with the fine structuring has a support section.
  • the at least one section with the fine structuring has a joining section.
  • a preferred development of the invention provides that coarse structuring is formed by wave-shaped structuring with beads and domes enclosed by the beads, the beads being formed integrally and with a radius of curvature opposite to the curvature of the calottes.
  • the beads differ greatly from the folds formed during buckling-vaulting in terms of their bending radius in relation to the thickness of the material web.
  • soft aluminum sheet of thickness 0.3 mm is provided with a crest-shaped (hexagonal with slightly curved folds / beads) structure of key width 33 mm.
  • the ratio of the bending radius of the bead to the material thickness (3D-wave) is 13.
  • the ratio of bending radius of the fold to thick material (buckling / vault structure) is 5.
  • stainless steel sheet (4301) of thickness 0.25 mm with a wappenförmigen structure of the wrench size 33 mm provided.
  • the ratio of bending radius of the bead to the material thickness is 16.
  • the ratio of bending radius of the fold to the material thickness is 7.
  • an elastic intermediate layer of thickness 4 mm and the Shore hardness 60 was used for the generation of the bead.
  • An advantageous embodiment of the invention can provide that the calottes in a central Kalotten Siemens have a shape which is at least approximate to a spherical shell shape.
  • the spherical shell shape arises from the fact that with the help of the elastic intermediate layer of the dynamic breakdown as in buckling / Völb Modellieren cushioned and slowed down. This gives the beads a gentler radius of curvature than the folds. Therefore, with a further increase in the compressive force (on the elastic intermediate layer), the calottes can form uniformly round. This is with the folds and the dynamic formed by the punch Hollow bulges and vault structures are not.
  • the beads are formed integrally according to one or a combination of a plurality of geometric basic shapes from the following group of geometric basic shapes: triangle, quadrangle, in particular square, rectangle, rhombus or parallelogram, pentagon, hexagon and octagon.
  • a preferred embodiment of the invention provides that the beads are formed according to a uniform geometric basic shape.
  • the beads are formed in all directions, namely in the production direction and transversely to the production direction, each with a substantially uniform bead height.
  • An advantageous embodiment of the invention can provide that for at least a part of the calotte a Kalottenober Structure is broadly diffuse reflective, wherein at least the part of the calotte is formed with the broadly diffusely reflecting Kalottenober configuration as deep calotte.
  • a dome surface is directionally reflective for at least part of the dome, wherein at least the part of the dome with the directionally reflecting dome surface is formed as flat dome.
  • a preferred embodiment of the invention provides that the roughing is a self-organizing structuring.
  • the web material is a material or a combination of materials selected from the following group of materials: metal, plastic, fibrous materials, in particular paper and paperboard, fibrous tissue and mesh fabric.
  • An advantageous embodiment of the invention can provide that the web material is formed in a sandwich construction, in which at least one intermediate web is arranged between two outer webs.
  • a preferred development of the invention provides that the web material is anodized aluminum sheet.
  • beulGermanABLE webs can be provided transversely to their direction with a smooth edge and in their direction with a finely textured edge that can be easily add to a frame, without causing disturbing differences in length between the beul gleich striv area and the smooth or fine-textured edge disturbing undulations, distortions or a "frog" occur in the structured material web.
  • Numerous examples based on steel sheets structured in this way have confirmed this, for example with a conventional steel sheet, such as those used on buses.
  • This gentle curvature stabilizes the material web in such a way that the difference in length of approximately ⁇ 0.5% between the gathered, beul poetic investigating area and the smooth edge area is compensated. This is preferably achieved when a broad edge is selected transversely to the direction of travel of the material web.
  • a bead in particular an approximately step-shaped, narrow longitudinal bead, is additionally formed between the bulge-shaped / wavy coarse-structured region of the material web and the finely structured edge region. It could have been expected that this longitudinal bead on the edge causes a disturbing, locally geometric extension of the slightly gathered material web and thereby causes distortion of the material web. However, the opposite was stated. Obviously, the bead stabilizes the structured material web.
  • the advantages of the bead are that it acts as an additional stiffening of the structured material web and that it also causes a decoupling between the beul Vietnamese striving, middle region of the material web on the one hand and their finely textured edge region on the other hand, and so instabilities between two adjacent, differently formed structures are avoided.
  • a conceivable one disadvantageous difference in length between the two gathered, structured areas and the bead, which is preferably a step-shaped, narrow longitudinal bead, is compensated by the large stiffnesses of the adjacent, wide, beulstructured or finely structured regions of the material web.
  • the structured material webs / metal sheets were additionally provided with finely structured edges and with a bead, because this would make the structuring process even more complicated.
  • the opposite is the case: with the help of the bead and the finely textured edges, the flatness of the structured material web is significantly improved. The improved flatness even remains even if the edge regions (beading and fine structures) are separated again from the structured material web. This can be explained as follows: When structuring the web, the structuring roller moves in such a way that press their support elements transversely to the direction of the web to be structured against the concave side of the web and wherein the convex side of the web is pressurized.
  • the material web is thereby somewhat gathered in its running direction, so that depressions / calottes and adjacent folds / bulges form virtually free.
  • This forming process can be considered in a very rough approximation as a deep drawing, wherein the thin material in the running direction of the web flows slightly (into the troughs).
  • the finely structured edges of the structured material web consist of either wave-shaped or polyhedral structures and are adapted in such a way as to cause gathering (shortening), which is approximately the shortening of the beul Vietnamese convinced Material web corresponds and wherein at the same time the texture depths at the edges are much lower than that of the troughs of the buckling structures.
  • such wave lengths are preferably selected as wavy fine structures, which are obtained when a smooth material is provided at the edge with a stepped longitudinal bead and bent over a roller.
  • uniform, wavy structures often appear on the edge of the thin material web.
  • the material web is flat between two wave amplitudes. So smooth edge surfaces are achieved, which facilitate the joining very much.
  • These fine structures can be used in all polyhedral coarse structures, such as hexagonal, crest-shaped, wavy or faceted structures.
  • the polyhedral fine structures at the edge of the material web consist of smaller hexagonal or crest-shaped structures, which are preferably adapted to the larger hexagonal or crest-shaped structures in the middle of the material web.
  • the refinement of the fine structures preferably takes place with the aid of geometrically adapted support elements, for example on a roller or roller in continuous operation or with the aid of geometrically adapted shaping tools, such as punches and dies in discontinuous operation.
  • the fine structures can also consist of quadrilaterally offset or rhombic structures. In this way, can be dispensed with a bead, because no disturbing transitions occur with instabilities between the beul gleich striv center and the finely textured edge of the web or the metal sheet. However, it can also be a bead between the beul gleich striv center of the web and its finely textured edge are arranged to further stiffen the web.
  • the structured material web is produced with a finely structured / smooth edge in a two-stage, preferably continuous process.
  • a smooth material web is structured in the first step by the material web is supported from its curvature out on its inside by supporting elements and from the outside, preferably applied by means of an elastic roller with pressure.
  • the material web is preferably provided over the entire surface with the structure. This allows for structuring different web widths a high flexibility when using the same support roller and the same elastic pressure roller.
  • a smooth edge in the running direction of the structured material webs can be obtained if lateral recesses are provided in the elastic pressure roller.
  • a smooth edge transversely to the direction of the material web is achieved in that the pressurization is interrupted in predetermined lengths of the material web. This can be achieved either by an adapted recess of the elastomer on the pressure roller and / or by an adapted, stepwise delivery of the support element roller.
  • the fine structures are produced by means of forming tools, preferably by roll forming on the edge of the material web. It can also be generated at the same time a longitudinal bead. Between the first and the second step and after the second step, the web can be directed.
  • the structured material web is produced with a finely textured / smooth edge in an integrated, single-stage, preferably continuous process, wherein the two steps mentioned take place simultaneously.
  • the center of the support element roller is equipped with its support elements for the production of the larger structures.
  • the two ends of the support element roller are equipped with the support elements or shape contours for producing the fine structures and possibly for the longitudinal bead.
  • the pressure roller has in its center an elastomer for the pressurization (for structuring) and at both ends of the incorporated shape contours for the production of fine structures. These shape contours can consist of rigid or elastic materials.
  • a further embodiment provides that initially a bulge / wave-structured material web is produced, oriented and then cut to form, for example, structured sheet metal sections.
  • the metal sheets structured in this way can also have smooth edges transversely to their running direction. You can also have laterally smooth edges.
  • the fine structures and possibly a bead at the edges of the web are introduced by means of adapted forming or embossing tools, preferably by two opposing each other oppressive roles. These forming and embossing tools are made of rigid or elastic materials.
  • the fine structures and possibly the bead can be attached to all sides of the structured metal sheet.
  • a further embodiment consists in that finely structured regions are introduced alternatively or additionally in the middle coarsely structured region of the structured material web, namely between two regions of the coarse texturing, optionally using at least one bead.
  • finely structured regions are introduced alternatively or additionally in the middle coarsely structured region of the structured material web, namely between two regions of the coarse texturing, optionally using at least one bead.
  • the coarse-structured material web not only receives fine structures at its edge portions, but is also provided with transition structures.
  • These transition structures are preferably disposed between the coarse structures and the fine structures and have a smaller feature size and depth than the coarse feature elements.
  • the transition structures have the advantage that although they are less rigid than the coarse structure elements, but a smoother transition from the coarse to give the fine structures.
  • the transition structures are preferably formed in the case of a roll-shaped coarse patterning in that a structurally appropriate fanning out of folds of the coarse patterning takes place.

  • the temporal gravity remains low in a direction transverse to the material web.
  • the structuring tool for the fine / transitional structuring of the material web intervenes spatially and temporally. In this way, the forces acting on the material edge and thus the machine cost remains relatively low.
  • An additional hold-down device can ensure that the material web is fixed with low pressure.
  • a further embodiment consists in the fact that several process steps are linked together directly to a quasi-continuous overall process in order to drastically reduce the throughput time and to improve the economic efficiency.
  • the flat material web is at the same time in the middle region with coarse textures and at the lateral edges (in the running direction) with fine textures and optionally

Also, in the case that a fine structure without additional beading is to arise (corresponding to Fig. 6 to 12), analogous applies to the hexagonal or the crest-shaped structures with wrinkles and for the three-dimensional wave-like structures with beads, because the initiation of the structures based on The laws of controlled self-organization to the dynamic breakdown proceed analogously.
