Definitions

  • the invention relates to a method and a mobile device for electromagnetic forming and / or cutting a poorly electrically conductive or electrically non-conductive sheet material using at least one drive plate.
  • the invention also relates to a specially designed flat material.
  • a flat material is to be understood as meaning a sheet-like material which is dimensionally stable at room temperature and whose thickness is low with respect to the areal extent. It is preferably provided that such a flat material is present in the form of a component or molded part or semifinished product. Under a poorly electrically conductive flat material is to be understood in the following priority that the specific conductivity of the material is significantly worse than that of copper.
  • the flat material to be formed is positioned between a coil and a shaping die and subsequently deformed into the die by means of magnetic pressure force.
  • a so-called blowing plate is arranged between the to be formed flat material and the coil.
  • a current is induced in the electrically conductive blowing plate, to which the magnetic field of the coil exerts a repulsive pressure force.
  • the kinetic energy occurring here in the blowing plate is transmitted by direct contact with the flat material to be formed.
  • the blowing plate is clamped to the reshaped sheet, such. B. in the DE 10 2005 013 539 A1 and DE 10 2005 013 540 A1 shown. This is complex and often leads to unsatisfactory results.
  • An object of the invention is to show ways in which the disadvantages associated with the prior art can be avoided or at least reduced.
  • the solution of the problem also extends to a specially designed flat material and to a mobile device for performing a forming and / or cutting operation, which is in particular a forming and / or cutting device.
  • the solution of the above object is achieved, on the one hand, by adhering or gluing the blowing sheet at least locally in the forming and / or cutting region onto the flat material to be formed and / or cut, for which purpose the blowing sheet is made self-adhesive.
  • the sticking of the blowing plate takes place before the cutting and / or forming process.
  • a surface bonding is provided, wherein the forming and / or cutting area can be formed flat or with a spatial shape.
  • a line-shaped or selective adhesive application can be provided.
  • a cut line may have an open or a closed course.
  • a cutting line may have a planar or a spatial or three-dimensional course.
  • the blowing plate is also formed from a flat material, which need not necessarily be a metal sheet, as explained in more detail below. The sticking of the drive plate is not precluded that this can be additionally clamped in a conventional manner.
  • the sticking sheet is self-adhesive.
  • the blowing plate is provided at least on one side with an adhesive layer, which adheres to the sheet z. B. is protected by a protective film or the like, which must then be removed on site and before bonding.
  • the adhesive layer may be formed as a surface applied adhesive film.
  • the adhesive layer may be in the form of adhesive film strips or adhesive film webs, adhesive film dots or the like. Instead of such an adhesive film, adhesive dots or the like may also be provided. It can likewise be provided that the flat material to be reshaped and / or cut is already provided with an adhesive layer according to the preceding explanations, at least in the forming and / or cutting region.
  • the sticking plate to be stuck is provided as a prefabricated adhesive pad.
  • a prefabricated adhesive pad is understood to mean a piece of sheet metal or the like adapted in the contour (outline) and / or shaping to the forming and / or cutting region. This makes it possible to provide an optimized for the pressure force training blowing plate.
  • the adhesive pad is preferably provided on one side with an adhesive layer, as explained above. Such adhesive pads may be provided as series parts or made individually as needed, especially on site. Since the driving plates are wear parts, the amount of waste can be reduced by using suitable prefabricated driving plates.
  • such an adhesive pad with respect to the substantially predetermined by the die contour of the forming and / or cutting area is formed with a smaller and primarily only slightly smaller contour, this blowing plate is then glued within the actual forming and / or cutting area on the reshaped and / or to be cut flat material.
  • the blowing plate can mitgeformt or pressed together with the sheet through a cutting die, as explained in more detail below in connection with the figures.
  • the adhesive pad is formed larger than the forming and / or cutting area and thus z. B. can be additionally clamped on its outer edge.
  • the forming and / or cutting process several scenarios are possible.
  • the glued blowing sheet is formed and / or separated together with the flat material to be formed and / or cut.
  • the glued-on blowing plate is detached from the flat material during forming and / or cutting, as explained in more detail below in connection with the figures.
  • the thickness of the blowing plate is less than or equal to 1 mm, preferably less than or equal to 0.8 mm, in particular less than or equal to 0.5 mm and particularly preferably less than or equal to 0.3 mm.

  • B. may be a plastic over-molded metal foil.
  • the flat material to be reshaped and / or cut can be a metal sheet, in particular a steel sheet, a laminate sheet, in particular a sandwich sheet containing plastic, or an organic sheet. Furthermore, the flat material to be formed and / or cut can also be a plastic material or a plastic-containing material. These materials are preferably in the form of semi-finished products (for example plates, profiles and the like) or spatially shaped components. To transform these materials, a separate heat input may be required.
  • a flat material to be formed and in particular to be cut is a plastic material, preferably a fiber-reinforced plastic material and in particular a CFRP material.
  • Fiber-reinforced plastic materials are understood to be dimensionally stable and, in particular, also cured composite materials which consist of a plastic matrix and reinforcing fibers embedded therein, in particular carbon fibers. These materials are preferably in the form of semi-finished products (for example plates, profiles and the like) or spatially shaped components.
  • the cutting of fiber-reinforced plastic materials by the method according to the invention represents a very interesting aspect, since conventional devices for mechanical cutting of these materials, due to the fiber content contained therein, are subject to very high wear.

  • CFRP carbon fiber reinforced plastic material
  • the cutting takes place without relative movements between tool parts, only a relatively small amount of wear occurs on the cutting edge or edges, whereby the operating costs are relatively low. Further advantages include good reproducibility of the cutting results and short processing times.
  • cuts in difficult to access component areas are possible, which are not accessible for mechanical cutting elements or for a cutting laser beam.
  • the cutting of fiber-reinforced plastic materials can also be carried out with only clamped driving plates and offers significant advantages over the conventional mechanical cutting of these materials.
  • the solution of the above object is also achieved by the fact that the blowing plate is incorporated or embedded at least locally and preferably only locally in the forming and / or cutting area in the flat material to be reshaped and / or cut.
  • the flat material to be formed and / or cut is provided, as it were, with at least one already integrated blowing plate for the cutting and / or forming process, wherein the at least one blowing plate is arranged in an area to be subsequently formed and / or cut.
  • a driving plate is z. B. so incorporated into the reshaped and / or to be cut flat material, that this forms part of the surface in the forming and / or cutting area or at least positioned near the surface. It is preferably provided that such a blowing plate is a blowing film (i.e., the film thickness is 0.5 mm or less).

Further developments are analogous to the preceding and following explanations.
  • a drive plate (possibly also of wires or wire mesh) z. B. be achieved in that in the curing tool at the appropriate location or at the appropriate places a metal foil is inserted, which is then embedded as close to the surface as possible in the composite material.
