Definitions

  • the invention relates to a pressing tool with a pressing surface and a method for producing the pressing tool.
  • Pressing tools for example in the form of pressing sheets, endless belts or embossing rollers, are used in the woodworking industry, for example, to produce furniture, laminates or panels, i.e. workpieces in general.
  • the workpieces are pressed with the pressing surface of the pressing tool, so that the workpieces receive surfaces corresponding to the pressing surface.
  • the WO 2009/062488 A2 discloses a pressed sheet with a structured pressed surface.
  • the textured press surface includes a structure that has a mountain-like surface with valleys and peaks and a full-surface chrome layer. Using the pressing surface, a workpiece designed as a material plate with a structured surface can be produced.
  • the WO 2008/120058 A1 discloses a pressing tool whose pressing surface is formed by a layer consisting of a metal matrix with mineral or ceramic particles embedded therein.
  • the press surface is subject to wear, so the layer forming the press surface wears away over time.
  • the document DE 10 2014 212448 A1 discloses pressing tool according to the preamble of claim 1 and a corresponding method.
  • the object of the invention is to provide a pressing tool with a structured pressing surface, in which wear of the pressing tool can be detected in a relatively simple manner.
  • the object of the invention is achieved by a pressing tool according to claim 1.
  • a further aspect of the invention is a method for producing the pressing tool according to the invention, with the features of claim 6.
  • the pressing tool according to the invention is, for example, an endless belt, an embossing roller or preferably a pressing plate and comprises the pressing surface, which has a structure of elevations and depressions.
  • the pressing surface is therefore a structured pressing surface with elevations and depressions. This gives the workpiece a structured surface corresponding to the structure of the structured pressing surface.
  • the workpiece is, for example, a material plate.
  • a material plate This includes, for example, a carrier, for example an MDF board or a chipboard, which is pressed with a resin or plastic-coated carrier (e.g. paper) using the pressing tool.
  • the material plate can also be a so-called luxury vinyl tile (LVT).
  • the pressing surface of the pressing tool according to the invention is at least partially formed by the wear layer.
  • the wear layer can be formed over the entire surface or partially.
  • the pressing tool includes the indicator layer, which is arranged below the wear layer.
  • the indicator layer is in particular below the Wear layer arranged so that it is arranged directly below the wear layer or that the wear layer rests on the indicator layer.
  • the pressing tool includes in particular a base structure on which the indicator layer is arranged.
  • the indicator layer is, for example, an indicator layer made of metal or plastic or is a paint indicator layer.
  • the wear layer is, for example, a wear layer made of metal or plastic, or is a paint indicator layer.
  • the plastic preferably comprises polyetheretherketone or consists of polyetheretherketone.
  • the basic structure is in particular made of metal such as steel, and the indicator layer and the wear layer are, for example, made of metal, i.e. electrically conductive, which makes it possible to apply the wear layer to the indicator layer using a galvanic or chemical process.
  • the structure of the basic structure essentially corresponds to the structure of the pressing surface.
  • the indicator layer is intended to indicate wear of the wear layer arranged on the indicator layer, i.e. in particular also wear of the pressing surface.
  • the indicator layer therefore has a different optical property than the wear layer. At least that's the wear layer partly worn so badly that it is completely removed, at least in some areas, the indicator layer is visible in these areas. Due to the different optical properties, this is then particularly visible to the human eye, so that a person can recognize relatively easily when the pressing tool is too worn.
  • the optical properties of the indicator layer are achieved by means of the particles embedded in it.
  • the optical properties are, for example, a color or a fluorescence.
  • the particles of the indicator layer are therefore, for example, color particles, so that the indicator layer has a corresponding color, and/or fluorescent particles, so that the indicator layer has fluorescent properties.
  • the particles of the indicator layer in particular have a size in the micrometer or nanometer range.
  • the indicator layer is preferably an indicator layer made of chromium-free metal, preferably an indicator layer made of nickel.
  • the metal wear layer is also preferably chromium-free, for example nickel.
  • mineral particles can be embedded in it.
  • the mineral particles in particular have a Mohs hardness of at least 8.
  • the mineral particles can have a size in the nanometer or micrometer range. This allows the mineral particles to be relatively homogeneous in the wear layer are embedded, which gives the wear layer a relatively homogeneous hardness over its entire surface.
  • the size of the individual mineral particles can be different or essentially the same.
  • the mineral particles preferably have a volume fraction of at least 50% based on the volume of the wear layer with mineral particles embedded therein. Due to the size, volume fraction and type of minerals of the mineral particles, the desired degree of wear of the wear layer can be adjusted.
  • the mineral particles are preferably diamond particles or industrial diamond particles.
  • the minerals silicon carbide, boron nitride, boron carbide, aluminum oxide and titanium oxide in particular can also be used as mineral particles.
  • the structured pressing surface is in contact with the workpiece and is therefore subject to wear. This wear is particularly pronounced in the areas of the elevations, at least in the area of certain elevations.
  • the indicator layer is a partial indicator layer, which is arranged only in areas below the wear layer that are assigned to the elevations or predetermined elevations.
  • the mask and the partial indicator layer are applied in particular depending on the image data assigned to the structure of the pressing surface.
  • the base structure can be treated before arranging the full-surface metal indicator layer, for example to modify the structure of the base structure.
  • This treatment can include mechanical treatment and/or galvanic and/or chemical treatment of the basic structure and/or the basic structure can be treated with a laser.
  • the treatment of the basic structure can also be a thermal treatment, for example annealing, in order to harden it, for example.
  • the structure of the pressing surface is particularly associated with a natural material, such as wood or stone. In order to preserve the structure of the pressing surface, it can be provided that a template, e.g. a piece of wood or a stone, is scanned to obtain image data.
  • This image data includes, in particular, information about the structure that the structured pressing surface should have.
  • the image data used to produce the partial indicator layer can be the scanned image data or image data generated from it.
  • the wear layer can be a full-surface wear layer made of metal.
  • a partial wear layer made of metal can be arranged on the full-surface wear layer made of metal. In this case, the partial wear layer made of metal and areas of the full-surface wear layer on which the partial wear layer made of metal is not arranged form the pressing surface.
  • the full-surface wear layer and the partial wear layer made of metal are preferably produced using a galvanic or chemical process.
  • the full-surface wear layer made of metal and the partial wear layer made of metal each have a level of gloss.
  • the gloss levels of the full-surface wear layer made of metal and the partial one differ Wear layer made of metal from one another, so that the surface of the workpiece produced with the pressing tool also has areas of different degrees of gloss.
  • the full-surface metal wear layer can be treated before applying the partial metal wear layer.
  • This treatment can include mechanical treatment and/or galvanic and/or chemical treatment of the full-surface wear layer and/or the full-surface wear layer can be treated with a laser.
  • Treating the full-surface wear layer can also be a thermal treatment, for example annealing the full-surface wear layer, for example to harden it. If the full-surface wear layer is a full-surface wear layer made of nickel, thermal treatment can cause it to have a hardness of approximately 1100 Vickers or more.
  • the partial wear layer made of metal can be treated additionally.
  • This treatment can include mechanical treatment and/or galvanic and/or chemical treatment of the partial wear layer made of metal and/or
  • the partial metal wear layer can be treated with a laser.
  • the treatment of the partial metal wear layer can also be a thermal treatment, for example annealing the partial metal wear layer, in order to increase its wear resistance.
  • additional mineral particles can be embedded in the partial metal layer.
  • the mineral particles and the other mineral particles can have the same size, the same volume fraction based on the volume of their metal layer and/or the same type of minerals.
  • the material of the partial metal layer and the full-surface metal layer can be the same or different.
  • the pressing surface can be changed, for example, through mechanical or chemical post-treatment or adapted to specific requirements.
  • the printing of the partial indicator layer made of plastic or the partial paint indicator layer is preferably carried out depending on the image data assigned to the structure of the pressing surface.
  • the base structure can be treated with the indicator layer before arranging or coating the base structure, so that preferably the paint indicator layer adheres the plastic indicator layer better to the base structure.
  • This treatment can be a mechanical treatment of the base structure, due to which, for example, the surface of the base structure is roughened, so that the paint indicator layer or the plastic indicator layer adheres better to the base structure.
  • Treating the base structure can include galvanic and/or chemical treatment of the base structure and/or treating the base structure with a laser. Due to the treatment of the basic structure, for example, the structure of the basic structure can be refined.
  • the different degrees of gloss of the plastic wear layers can be achieved, for example, by hardening the plastic wear layers, for example by UV irradiation, electron beam or laser hardening, or by exposure to different temperatures.
