Definitions
- the invention relates to a pressing tool and a method for producing a pressing tool.
- the pressing tool comprises a structured pressing surface.
- Pressing tools e.g. in the form of press plates, endless belts or embossing rollers, are used in the woodworking industry, for example, to produce furniture, laminates or panels, i.e. general workpieces.
- the workpieces are pressed with the pressing surface of the pressing tool, so that the workpieces have surfaces corresponding to the pressing surface.
- WO 2009/062488 A2 discloses a press plate with a structured press surface.
- the structured press surface includes a structure that has a mountain-like surface with valleys and heights.
- a workpiece in the form of a material plate with a structured surface can be produced by means of the pressing surface.
- the structured pressing surface comprises a full-surface chrome layer that rests against the material plate during pressing.
- the structured press surface is produced by deep etching.
- WO 2015/036070 A1 discloses a pressing tool with a structured pressing surface.
- the structured press surface is produced by superimposed metal layers.
- a mask is applied at least once in order to cover partial areas and at least once a metal layer is applied to the uncovered areas in order to build up the structured press surface consisting of elevations and depressions. These two process steps are repeated until a desired structure depth of the structured press surface is reached.
- the structured pressing surface can then be provided with a hard chrome layer.
- WO 03/016034 A1 discloses a further press plate with a structured press surface. In order to reduce wear on the press plate, the structured press surface is provided with a coating made of carbon with diamond-like layers and a surface hardness of over 1800 HV according to Vickers.
- WO 2008/120058 A1 discloses a pressing tool, the pressing surface of which is formed by a layer consisting of a metal matrix with mineral or ceramic particles embedded therein.
- the object of the invention is to specify an improved pressing tool with a structured pressing surface.
- a pressing tool for producing a workpiece having a pressing surface which has a structure of elevations and depressions, a full-surface metal layer, and a partial metal layer arranged on the full-surface metal layer, the partial metal layer and the partial metal layer Free areas of the full metal layer form the pressing surface, mineral particles are embedded in the partial metal layer, and the partial metal layer is arranged in predetermined areas on the full metal layer.
- the full-surface metal layer and the partial metal layer are produced in particular using a galvanic or chemical process.
- the predetermined areas of the partial metal layer are preferably assigned to the elevations or predetermined elevations of the pressing surface.
- Another aspect of the invention relates to a method for producing the press tool according to the invention, having the following method steps:
- the pressing surface can be cleaned in order to remove residues of the mask.
- the press tool according to the invention is, for example, an endless belt, an embossing roller or preferably a press plate and comprises the press surface.
- the workpiece is, for example, a material plate.
- a material plate This includes, for example, a carrier, e.g. an MDF board or a chipboard, which e.g. is pressed with a resin or plastic coated or impregnated carrier, e.g. in the form of paper, using the pressing tool.
- the material plate can also be a so-called luxurious vinyl tile (LVT).
- the pressing surface is formed by the full metal layer and the partial metal layer, which is arranged in the predetermined areas on the full metal layer.
- the predetermined areas are in particular assigned to the elevations or specific elevations of the pressing surface, i.e. the partial metal layer is thus preferably only located essentially on the elevations and not in the depressions of the pressing surface.
- the 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 preferably in the area of certain elevations, which is why, according to the invention, the mineral particles are embedded in the partial metal layer.
- This increases the Wear resistance of the partial metal layer and thus the wear resistance of the pressing surface at least in the predetermined areas and thus preferably at least in the areas associated with the elevations or certain elevations of the pressing surface.
- the mineral particles of the partial metal layer in particular have a Mohs hardness of at least 8.
- the mineral particles have a size in the nanometer or micrometer range.
- the mineral particles can be embedded relatively homogeneously in the metal layer, as a result of which the partial metal layer has a relatively homogeneous wear resistance 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 partial metal layer with mineral particles embedded therein.

- the mineral particles are in particular diamond particles.
- the diamond particles are in particular industrial diamond particles, ie the diamond or, in general, the mineral particles can be produced artificially.
- the minerals silicon carbide, boron nitride, boron carbide, aluminum oxide and titanium oxide in particular can also be used as mineral particles.
- the mineral particles are designed, for example, as mineral powder, in particular as diamond powder and preferably as industrial diamond powder.
- the pressing tool can in particular be produced as a function of the structure of the image data assigned to the structured pressing surface.
- the mask is preferably applied as a function of these image data which are assigned to the structure of the structured press surface.
- the pressing surface is assigned to a natural material such as wood or stone.

- image data include, in particular, information about the structure that the press surface should have.
- the image data obtained as a result of the scanning can be edited manually, for example, in order to obtain the image data assigned to the structure of the press surface.
- the full-area and partial metal layers are preferably produced using a galvanic or chemical process. If the partial metal layer is produced by electroplating with the addition of the mineral particles, this is in particular a partial metallic dispersion layer in which the mineral particles are embedded.
- the partial metal layer is preferably a chromium-free metal layer.
- the chromium-free partial metal layer is in particular a partial nickel layer.
- the full-surface metal layer is also preferably chromium-free and in particular a full-surface nickel layer.

- This treatment can be a mechanical treatment and / or a galvanic and / or a chemical treatment of the encompass full-surface metal layer and / or the treatment of the full-surface metal layer can take place with a laser.
- the treatment of the full-surface metal layer can also be a thermal treatment, for example tempering of the full-surface metal layer, in order to harden it, for example.

- the full-surface metal layer and the partial metal layer each have a degree of gloss.
- the degrees of gloss of the full-surface metal layer and the partial metal layer preferably differ from one another, so that the surface of the workpiece produced with the pressing tool also has areas of different degrees of gloss.
- the further mineral particles are in particular further diamond particles.
- the further diamond particles are, in particular, further industrial diamond particles, i.e. the diamond or, in general, the mineral particles can be produced artificially

- the material of the partial metal layer and the all-over metal layer can be the same or different.
- this comprises a basic structure made up of a plurality of base metal layers lying one above the other, on which the full-surface metal layer is arranged. Mineral particles can also be embedded in the superimposed base metal layers of the base structure. This increases the wear resistance of the entire press tool.
- the base metal layers are preferably chromium-free, in particular base nickel layers.
- the mineral particles of the base metal layers can have the same size, the same volume fraction based on the volume of the base metal layers and / or the same type of minerals as the mineral particles of the metal layer.

Then the full-surface metal face is arranged on the basic structure, if necessary with the addition of the further mineral particles.
- This type of production of the basic structure can take place without etching, as a result of which a relatively environmentally friendly production is made possible.
- the basic structure can be treated before the full-surface metal layer is arranged in order, for example, to modify the structure of the basic structure.
- This treatment can include a mechanical treatment and / or a galvanic and / or chemical treatment of the basic structure and / or the treatment of the basic structure can take place with a laser.
- the treatment of the basic structure can also be a thermal treatment, for example tempering, in order to harden it, for example.
- each of the base metal layers is thermally treated, for example tempered, before the subsequent base metal layer is applied. This can increase the hardness of the entire basic structure.
