Definitions

  • the present invention relates to a sheet metal element according to the preamble of claim 1 and a method for its production. Furthermore, the invention is directed to a profile element, which is made of such a sheet metal element.
  • Flat metal elements of the type mentioned are used for example in the production of profiles.
  • profiles can be, for example, uprights, as they are used in particular for interior installation for fixing plate-shaped elements, or corner profiles, which are usually used to protect corners under plaster.
  • corner profiles which are usually used to protect corners under plaster.
  • Each of the apertures has on one side in the direction between the two outer edges of the metal element only a connecting portion, so that the metal element has a relatively low rigidity.
  • a flat metal element of the type mentioned in such a way that the openings are formed without loss of material, while at the same time substantially no stresses should be present within the material. Furthermore, the metal element should have a high rigidity and it should, compared to the starting material a large material broadening or area expansion be possible.
  • the apertures in the flat metal element are thus not produced by a stretching process, but by a folding over of sections, so that an elongation or an extension within the metal element, as it is present in expanded metal, is avoided.
  • the folded-over sections are arranged so that unfolding of the two outer edge regions of the metal element occurs during the operation, whereby the desired material broadening or expansion is achieved.
  • the openings in the metal element in an integral manufacturing process can be generated and the desired rigidity and stability are ensured.
  • the outer sections are opposite to each other, that is, folded in opposite directions.
  • one of the outer sections is at the top of the middle section and the other outer portion folded over to the underside of the central portion.
  • the sections can be folded both facing each other and pointing apart.
  • outer sections are folded in the same direction relative to one another, that is to say in the same direction.
  • both outer sections are folded to the same side, that is, both folded either to the top or both to the bottom of the central portion.
  • a plurality of apertures are formed at least in one of the edge regions. This is particularly useful if the flat metal element has an elongated design extending in the direction of the outer edges, since only through the openings a corresponding broadening of the metal element over its entire length is possible.
  • a plurality of apertures are formed in each of the edge regions. These openings are preferably distributed alternately in the two edge regions, wherein preferably each one section is associated with its folded outer sections at the same time each an opening of the first and an adjoining opening of the second edge region.
  • additional openings are formed in the central region.
  • the apertures formed in the middle region are advantageously designed in accordance with the apertures formed in the edge regions. It is thus possible to achieve an additional broadening of the metal element in that several according to the invention folded portions are provided between the outer edges lying one behind the other.
  • a portion is formed as a web with mutually parallel side edges.
  • the side edges of the section can also run obliquely to one another or, for example, can also be curved, as long as the folding over of the partial sections according to the invention is not prevented thereby.
  • at the ends of the sections may be provided deviating from the web shape, for example, laterally projecting surfaces.
  • the side edges and the webs parallel to each other or obliquely to each other.
  • the geometry is limited only by the fact that a folding of the outer sections and thus a unfolding of the two edge regions is not hindered.
  • the distance between the first and the second outer edge with folded-over sections is significantly greater than with unfolded sections.
  • the desired material broadening is achieved.
  • the distance with fold-over sections approximately between 1.3 and 4 times, in particular approximately between 2 and 3 times as large as unenfolded sections.
  • the openings are repeated at regular intervals, and this is the case for both in the edge regions Breakthroughs as well as for possibly formed in the middle region openings applies.
  • the openings can also repeat at irregular intervals.
  • the edge regions, with the exception of the apertures have a substantially planar surface.
  • the surface of the metal element with the exception of the openings is substantially flat. This can be achieved, for example, by flat-rolling the material thickenings present due to the folding over. This results in addition to the bending lines and the thin rolled folded sections a strain hardening, so that despite the folding of the material, the rigidity of the folded portions at least equal to the rigidity of the starting material. This is particularly important if the formed for example as webs sections are made relatively thin, since in this case, a high rigidity of the entire metal element is ensured by the work hardening despite these thin connection points between the two edge regions.
  • the folded outer sections with the middle section in each case close an angle of about 110 ° to 0 °, preferably from about 90 ° to 0 °, preferably from about 45 ° to 0 °, in particular from 10 ° to 0 °.
  • the outer sections are completely folded over, so that they enclose an angle of approximately 0 ° with the central section.
  • the folding process is not carried out until complete folding, so that three-dimensional Create structures. These can be used, for example, in the production of composites, filters or the like.
  • each of the folded outer sections which is directly connected to an edge region, continuously, in particular just in the associated with him edge region over.
  • each metal section adjoins the first and / or the second outer edge, which forms an angle profile together with the material extending between the first and the second outer edge.
  • the angle profile may be L-shaped, V-shaped, U-shaped, C-shaped or Z-shaped.
  • the sheet metal element can be easily used to form a profile.
  • the one or more metal sections may be formed either over the entire surface or, if desired, also be penetrated with openings according to the invention. If, for example, a plaster profile is to be produced, then the angle profile is advantageously designed in the shape of an L, wherein preferably both legs of the profile are provided with apertures according to the invention.
  • the openings in the middle base part, but not in the outer thighs are present. If necessary, the openings can also be formed directly in the bending lines of the angle profiles or only in one or more legs.
  • the metal element according to the invention can be used everywhere, where flat metal sections are used, e.g. in all types of open or closed metal profiles, e.g. also tube profiles.
  • the further metal portion or the further metal portions are formed integrally with the remaining part of the metal element, in order to maintain the single-stage manufacturing process in this way.
  • a third and a fourth edge region are present, which lie opposite each other and each extending transversely, in particular perpendicular to the first or second edge region.
  • the formation of the surface of the material web in this case corresponds in one direction from the third to the fourth edge region essentially to the formation of the surface in a direction from the first to the second edge region.
  • the metal element according to the invention can be used in many ways.
  • the metal element as a profile element, in particular as a corner or upright profile, as a protective grid, as a fence section, as a filter mat, as a soundproofing element, as a trellis, as tread element, as a reinforcing mat, as an insert in composite materials, as a cable duct, as a perforated tape, as an assembly, Acoustic or shading element or as Decorative profile can be used.
