Description
Pressing tool and method for producing a pressing tool
The invention relates to a pressing tool with a pressing surface and a method for producing a pressing tool.
Pressing tools, for example in the form of pressing plates, endless belts or embossing rollers are, for example, used in the woodworking industry, for example to produce furniture, laminates or panels, i.e. in general workpieces. The workpieces are pressed with the pressing surface of the pressing tool, such that the workpieces obtain surfaces corresponding to the pressing surface.
WO 2009/062488 A2 discloses a pressing plate with a structured pressing surface. The structured pressing surface comprises a structure that has a mountain-like surface with valleys and heights and a full-surface chromium layer. By use of the pressing surface, a workpiece formed as a material board with a structured surface may be produced.
WO 2008/120058 Al discloses a pressing tool, the pressing surface of which is formed by a layer, which consists of a metal matrix with mineral or ceramic particles embedded therein.
The pressing surface is subjected to wear, such that the layer forming the pressing surface wears off over time.
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 noticed relatively easily.
The object of the invention is achieved by a pressing tool for producing a workpiece with a pressing surface having a structure of protrusions and recesses, a wear layer with an optical property, the wear layer at least partially forming the pressing surface, and an indicator layer, which is arranged under the wear layer and in which particles having optical properties are embedded, so that the indicator layer has a corresponding optical property, which is different from the optical property of the wear layer.
A further aspect of the invention is a method for producing the pressing tool according to the invention, comprising the following method steps:
- applying the indicator layer to a base structure with the addition of the particles having the optical properties, - applying the indicator layer at least partially forming the pressing surface - applying the wear layer to the indicator layer.
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 protrusions and recesses. The pressing surface is therefore a structured pressing surface with the protrusions and recesses. Thereby, the workpiece receives a structured surface corresponding to the structure of the structured pressing surface.
The workpiece is, for example, a material board. It comprises, 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) by means of the pressing tool. The material board may 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 may have a full-surface or partial design.
The pressing tool comprises the indicator layer, which is arranged under the wear layer. The indicator layer is particularly arranged under the wear layer such that it is arranged directly under the wear layer and/or that the wear layer contacts the indicator layer.
The pressing tool particularly comprises a base structure, on which the indicator layer is arranged.
The indicator layer is e.g. an indicator layer of metal or plastic, or it is a lacquer indicator layer.
The wear layer e.g. a wear layer of metal or plastic, or it is a lacquer indicator layer.
The plastic preferably comprises polyether ether ketone or consists of polyether ether ketone.
The base structure is in particular made of metal, e.g. steel, and the indicator layer and the wear layer are of e.g. metal, thus electrically conductive, which makes it possible to apply the wear layer to the indicator layer by means of a galvanic or chemical method. The structure of the base structure essentially corresponds to the structure of the pressing surface.
In the case of an indicator layer of plastic or the lacquer indicator layer, it is preferably applied to the base structure by means of a printer. Such a production is relatively environmentally friendly.
In the case of a wear layer of plastic or the lacquer wear layer, it is preferably applied to the indicator layer by means of a printer. Such a production is relatively environmentally friendly.
The indicator layer is provided to indicate wear of the wear layer arranged on the indicator layer, thus in particular also wear of the pressing surface. Thus, the indicator layer has a different optical property than the wear layer. If the wear layer is at least partially worn so severely that it is completely removed at least in some regions, the indicator layer is visible in those regions. Due to the different optical properties, it then becomes visible to the human eye, so that a person can discern relatively easily when the pressing tool is worn too severely.
The optical properties of the indicator layer are obtained by means of the particles embedded therein. The optical properties are, for example, a color or a fluorescence. The particles of the indicator layer are therefore e.g. 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.
In order to increase the environmental friendliness, the indicator layer preferably is an indicator layer of chromium-free metal, preferably an indicator layer of nickel.
The wear layer of metal is preferably also chromium-free, for example of nickel.
In order to increase the wear resistance of the wear layer arranged on the indicator layer, mineral particles may be embedded in said wear layer.
Minerals are, in particular, mostly inorganic, homogeneous, mostly crystalline substances occurring in the earth's crust. The plurality of the minerals known today and recognized as distinct by the International Mineralogical Association are inorganic.
The mineral particles in particular have a Mohs hardness of at least 8. The mineral particles may have a size in the nanometer or micrometer range. Thus, the mineral particles can be embedded in the wear layer relatively homogeneously, whereby the wear layer obtains a relatively homogeneous hardness across its entire surface. The size of the individual mineral particles may be different or essentially the same.
The mineral particles preferably have a volume share of at least 50% with regard to the volume of the wear layer with mineral particles embedded therein. Due to the size, the volume share, and the type of the minerals of the mineral particles, the desired degree of wear of the wear layer can be adjusted.
Preferably, the mineral particles are diamond particles and/or industrial diamond particles. However, in particular the minerals silicon carbide, boron nitride, boron carbide, aluminum oxide, and titanium oxide may also be used as mineral particles.
During the production of the workpiece, the structured pressing surface is in contact with the workpiece and is therefore exposed to wear. This wear is particularly pronounced in the regions of the protrusions, at least in regions of certain protrusions. According to a preferred embodiment of the pressing tool, the indicator layer is a partial indicator layer, which is arranged only in regions under the wear layer, which are assigned to the protrusions or predetermined protrusions.
In the case of the indicator layer and the wear layer being made of metal, the production of this variant of the pressing tool particularly comprises the following method steps:
- applying a mask to the base structure, so that regions of the base structure, which are assigned to the protrusions or predetermined protrusions of the pressing surface, remain free of the mask, - applying the indicator layer of metal to the regions of the base structure free of the mask with the addition of the particles having the optical properties, by means of a galvanic or chemical method, and - applying the wear layer of metal at least partially forming the pressing surface by means of a galvanic or chemical method.
The application of the mask and of the partial indicator layer particularly takes place dependent on image data assigned to the structure of the pressing surface.
The base structure may be treated before the full-surface indicator layer of metal is arranged, for example in order to modify the structure of the base structure. This treatment may comprise a mechanical treatment and/or a galvanic and/or a chemical treatment of the base structure and/or the treatment of the base structure may be carried out with the aid of a laser. The treatment of the base structure may also be a thermal treatment, e.g. tempering in order to harden it, for example.
The structure of the pressing surface is, in particular, assigned to a natural material, such as wood or stone. In order to obtain the structure of the pressing surface, it can be provided that a model, for example a piece of wood or a stone is scanned to obtain image data. This image data in particular comprises information on the structure which the structured pressing surface should have. The image data used for the production of the partial indicator layer may be the scanned image data or image data generated therefrom.
The wear layer may be a full-surface wear layer of metal. A partial wear layer of metal may be arranged on the full-surface wear layer. The partial wear layer of metal and regions of the full-surface wear layer, on which the partial wear layer of metal is not arranged, form the pressing surface in this case.
The full-surface wear layer and the partial wear layer of metal are preferably created using a galvanic or chemical method.
The full-surface wear layer of metal and the partial wear layer of metal each have a degree of gloss. The degrees of gloss of the full-surface wear layer of metal and of the partial wear layer of metal are preferably different from one another, so that the surface of the workpiece produced using the pressing tool also has regions of different degrees of gloss.
The method for producing this variant of the pressing tool according to the invention may comprise the following method steps:
- applying a metal layer to the indicator layer over the full surface in order to obtain the full-surface wear layer of metal, - applying a mask to the full-surface wear layer of metal, in particular dependent on image data assigned to the structure of the pressing surface, so that predetermined regions of the full-surface wear layer of metal, which are assigned to the protrusions or predetermined protrusions of the base structure, remain free of the mask, and
- applying a further metal layer to the predetermined regions of the full-surface wear layer by means of a galvanic or chemical method, in particular dependent on the image data, in order to obtain the partial wear layer of metal arranged on the full surface wear layer.
The full-surface wear layer of metal may be treated before applying the partial wear layer of metal. This treatment may comprise a mechanical treatment and/or a galvanic and/or a chemical treatment of the full-surface wear layer and/or the treatment of the full-surface wear layer may be carried out with the aid of a laser. The treatment of the full-surface wear layer may also be a thermal treatment, e.g. tempering of the full-surface wear layer, in order to harden it, for example. If the full surface wear layer is a full-surface wear layer of nickel, the thermal treatment can allow for it to have a hardness of about 1100 Vickers or more.
The partial wear layer of metal may receive additional treatment. This treatment may comprise a mechanical treatment and/or a galvanic and/or a chemical treatment of the partial wear layer of metal and/or the treatment of the partial wear layer of metal may be carried out with the aid of a laser. The treatment of the partial wear layer of metal may also be a thermal treatment, e.g. tempering of the partial wear layer of metal, in order to increase its wear resistance.
In order to additionally make the pressing surface more wear resistant, further mineral particles may be embedded in the partial metal layer.
The mineral particles and the further mineral particles may have the same size, the same volume share with regard to the volume of its metal layer and/or the same type of minerals.
The material of the partial metal layer and the full-surface metal layer may be the same or different.
The pressing surface may be changed and/or adapted to specific demands, for example by means of a mechanical or chemical after-treatment.
If the wear layer is the wear layer of plastic or if it is a lacquer wear layer, in particular the indicator layer may be a partial indicator layer of plastic or a partial lacquer indicator layer, which is arranged on the base structure only in regions which are assigned to the protrusions or predetermined protrusions of the pressing surface. The production of this variant particularly comprises
- applying the indicator layer of plastic or the lacquer indicator layer to the regions of the base structure with the addition of the particles having the optical properties by means of a printer, and - applying the wear layer of plastic or the lacquer wear layer at least partially forming the pressing surface by means of a printer.
The printing of the partial indicator layer of plastic or of the partial lacquer indicator layer preferably takes place dependent on image data assigned to the structure of the pressing surface.
The wear layer at least partially forming the pressing surface may be a full-surface wear layer of plastic, on which a partial wear layer of plastic is arranged. The full surface wear layer of plastic preferably has a degree of gloss, and the partial wear layer of plastic has a degree of gloss that is different from the degree of gloss of the full-surface wear layer of plastic. The production of this variant particularly comprises
- applying a plastic layer to the indicator layer over the full surface in order to obtain the full-surface wear layer of plastic, and - applying a further plastic layer to the predetermined regions of the full-surface wear layer of plastic by means of a printer, in particular dependent on the image data, in order to obtain the partial wear layer of plastic arranged on the full-surface wear layer of plastic.
The base structure may be treated before arranging and/or coating the base structure with the indicator layer, so that preferably, the lacquer indicator layer the indicator layer of plastic adheres better to the base structure. This treatment may be a mechanical treatment of the base structure, due to which e.g. the surface of the base structure is, for example, roughened, such that the lacquer indicator layer or the indicator layer of plastic layer adheres better to the base structure. The treatment of the base structure may comprise a galvanic and/or chemical treatment of the base structure and/or the treatment of the base structure with the aid of a laser. Due to the treatment of the base structure, for example the structure of the base structure can be refined.
The different degrees of gloss of the wear layers of plastic may be obtained, for example by hardening the wear layers of plastic, for example by means of UV irradiation, electron beam or laser hardening, or by exposure to different temperatures.
The wear layer at least partially forming the pressing surface may be a full-surface lacquer wear layer, on which a partial lacquer wear layer is arranged. In particular, the full-surface lacquer wear layer may have a degree of gloss, and the partial lacquer wear layer may have a degree of gloss different from the degree of gloss of the full-surface lacquer wear layer. The production of this variant particularly comprises
- applying a lacquer layer to the indicator layer over the full surface in order to obtain the full-surface lacquer wear layer, and - applying a further lacquer layer to the predetermined regions of the full-surface lacquer wear layer by means of a printer dependent on the image data, in order to obtain the partial lacquer wear layer arranged on the full-surface lacquer wear layer.
Exemplary embodiments of the invention are shown in the enclosed schematic figures by way of example. These show:
Fig. 1 a pressing plate with a pressing surface in a perspective representation,
Fig. 2 a cutout from a lateral view of the pressing plate in a sectional representation,
Fig. 3 an intermediate state of the pressing plate during its production,
Fig. 3 a further intermediate state of the pressing plate during its production, and
Fig. 5 a cutout from an alternative embodiment of the pressing plate of the pressing plate in a sectional representation.
Fig. 1 shows, in a perspective representation, a pressing plate 1 with a pressing surface 2 as an example of a pressing tool, and Fig. 2 shows a cutout from a lateral view of the pressing plate 1 in a sectional representation. The pressing surface 2 comprises a structure of the protrusions 4 and recesses 3.
The structure of the pressing surface 2 is, in particular, assigned to a natural material that is wood in the case of the present exemplary embodiment.
By the pressing plate 1, a workpiece, e.g. a pressing plate, for example a laminate, can be produced by pressing. After pressing, the workpiece has a structured surface corresponding to the structure of the pressing surface 2.
In the case of the present exemplary embodiment, the pressing plate 1 comprises a base structure 10, a wear layer 11 at least partially forming the pressing surface 2, and an indicator layer 12.
In the case of the present exemplary embodiment, the base structure 10 is made of metal. The indicator layer 12 is arranged on the base structure 10 and/or under the wear layer 11, and in the case of the present exemplary embodiment, it is a partial indicator layer 12.
Particles 18 having an optical property are embedded in the indicator layer 12, so that the indicator layer 12 also has this optical property. The particles 18 are, e.g.
color particles, so that the indicator layer 12 has the color of said color particles. The particles 18 may be fluorescent particles, so that the indicator layer 12 is fluorescent. In particular, the indicator layer 12 may comprise only the color particles, only the fluorescent particles, or both types of particles 18.
The wear layer 11 is arranged on the indicator layer 12, meaning that the indicator layer 12 is arranged between the base structure 10 and the wear layer 11. The optical property of the wear layer 11 is different from the optical property of the indicator layer 12.
In the case of the present exemplary embodiment, the wear layer 11 is a full-surface wear layer 11 and forms the pressing surface 2.
In the case of the present exemplary embodiment, mineral particles, in particular industrial diamond particles 13, are embedded in the wear layer 11.
The wear layer 11 is made of metal, in particular of nickel, and the indicator layer 12 is also made of metal, in particular of nickel.
The wear layer 11 of metal was produced, for example by being applied to the indicator layer 12 of metal with the addition of the industrial diamond particles 13 by means of a galvanic or chemical method.
The wear layer 11 and/or the indicator layer 12 may also be made of plastic. The plastic layer preferably comprises polyether ether ketone. In this case, the layers of plastic may be applied, for example by means of printing.
The wear layer 11 may be a wear layer, which is applied in particular by means of printing.
The indicator layer 12 may be an indicator layer, which is applied in particular by means of printing.
In the case of the present exemplary embodiment, the pressing plate 1 comprises a base carrier, in particular a base carrier plate 14, for example of metal, on which the base structure 10 is arranged.
In the case of the present exemplary embodiment, the base structure 10 comprises multiple base metal layers 15 located on top of one another. The base metal layers 15 are preferably made of nickel.
In the case of the present exemplary embodiment, mineral particles, in particular industrial diamond particles 16, are embedded in the base metal layers 15, as well. The industrial diamond particles 16 of the base metal layers 15 may be embodied similarly to the industrial diamond particles 13 of the metal layer 11.
The base structure 10 may be produced, for example by applying a mask 17 shown in Fig. 3 at least once to a base metal layer 15 dependent on image data assigned to the structure of the structured pressing surface 2, in order to cover regions, and subsequently applying a further base metal layer 15 with the addition of the diamond particles 15 to the regions not covered by the mask 17. This is repeated until the base structure 10 has been formed. The base structure 10 is produced particularly dependent on image data assigned to the structure of the pressing surface 2, i.e. dependent on the protrusions 4 and recesses 5, by applying the masks 17 and the base metal layers 15, dependent on this image data, subsequently by means of the galvanic or chemical method.
Subsequently, the indicator layer 12 is applied to the base structure 10 with the addition of the particles 18.
In the case of the present exemplary embodiment, the indicator layer 12 is a partial indicator layer 12, which is arranged on the base structure 10 only in regions 20 which are assigned to the protrusions 4 or predetermined protrusions 4 of the pressing surface 2.
If the indicator layer 12 is an indicator layer 12 of metal, it may be produced by applying a mask 40 shown in Fig. 4 to the base structure 10 dependent on the image data assigned to the structure of the pressing surface 2, e.g. by means of printing, so that the regions 20 of the base structure 10 assigned to the protrusions 4 or predetermined protrusions 4 of the pressing surface 2 remain free of the mask 40. Subsequently, the indicator layer 12 is applied to the regions 20 of the base structure 10 free of the mask 40 with the addition of the particles 18 having the optical properties, by means of a galvanic or chemical method. Afterwards, the wear layer 11 of metal is applied to the indicator layer 12.
If the indicator layer 12 is an indicator layer 12 of plastic, it may be applied to the regions 20 of the base structure 10 by means of a printer with the addition of the particles 18. Subsequently, the wear layer 11 of plastic at least partially forming the pressing surface 2 is applied by means of a printer, in particular with the addition of the industrial diamond particles 18.
If the indicator layer 12 is a lacquer indicator layer, it may be applied to the regions 20 of the base structure 10 by means of a printer with the addition of the particles 18.
The application of the indicator layer 12 preferably takes place dependent on image data assigned to the structure of the pressing surface 2.
Fig. 5 shows a cutout from an alternative embodiment of a pressing surface 52 of the pressing plate 1 in a sectional representation. This pressing surface 52 is different from the pressing surface 2 shown in Fig. 2 in that the pressing plate 1 and/or the pressing surface 52 comprises a partial wear layer 53, in which further mineral particles, in particular further industrial diamond particles 54, are embedded. The partial wear layer 53 is arranged on the wear layer 11, so that the partial wear layer 53 and the regions of the wear layer 11 not covered by the partial wear layer 53 form the pressing surface 52.
The wear layer 11 may be pre-treated, for example chemically, mechanically, galvanically, or by means of a laser, before the application of the partial wear layer 53.
The wear layer 11 and the partial wear layer 53 in particular each have a degree of gloss that is different from the other.
If the wear layer 11 and the partial wear layer 53 is made of metal, the different degrees of gloss may be created, for example, by using metals with different kinds of gloss for the wear layer 11 and the further wear layer 53. It is also possible to use identical metals which have different degrees of gloss due to different ways of application.
The partial wear layer 53 of metal with the further industrial diamond particles 54 embedded therein is produced, for example by applying a mask to the wear layer 11 of metal, in which the industrial diamond particles 13 are embedded, for example by means of printing, in order to cover predetermined regions of the wear layer 11. Afterwards, a further metal layer is applied to the regions of the wear layer 11, which are not to be provided with the mask, with the addition of the further industrial diamond particles 54 by means of a galvanic or chemical method, in order to obtain the partial wear layer 53 with the further industrial diamond particles 54 embedded therein.
If the wear layers 11, 53 are made of plastic, the partial wear layer 53 with the further industrial diamond particles 54 embedded therein may be produced, for example by applying, on the wear layer 11, a further plastic layer to the predetermined regions 20 of the full-surface wear layer 11 of plastic by means of a printer, in particular dependent on the image data, in order to obtain the partial wear layer 53 of plastic arranged on the full-surface wear layer 11 of plastic.
The different degrees of gloss of the wear layers of plastic may be obtained, for example by hardening the wear layers of plastic, for example by means of UV irradiation, electron beam or laser hardening, or by exposure to different temperatures.
