Definitions

  • the invention relates to a method for producing decorative surfaces on base metals in individual steps.
  • DE OS 26 38 195 a process for the production of decorations has become known, according to which a decorative mask made of electrically insulating material is applied to a partial surface of the metallic object and the areas not covered by the decorative mask are built up by electroplating.
  • a decorative mask made of electrically insulating material is applied to a partial surface of the metallic object and the areas not covered by the decorative mask are built up by electroplating.
  • This is a structure that does not result in a flat metal decorative surface, but rather a non-slip surface design, as is the case with the object according to DE - OS 26 38 195, eg. B. lighter sleeves and the like is the case.
  • the method according to the invention is characterized in accordance with claim 1.
  • the metal parts obtained in this way can then be processed further to articles of daily use or jewelry and can also be further processed by rolling, embossing and / or punching.
  • the method according to the invention can also be used several times in succession to form different decorative shapes.
  • etched depressions according to claim 4 can be used for receiving and fixing decorative parts such as metals, stones or the like by means of galvanic edge coating.
  • an optionally acid-resistant and non-conductive, entire lacquer layer can also be applied to the base material, in particular platinum, instead of a lacquer mask, into which depressions can be made, including in the base metal, by means of hand or machine tools, since platinum is difficult to apply can be etched; however, this can also be done in combination with the previously described etching process.
  • the depressions in the base metal are then filled with metal until a flat surface is obtained.
  • the metal parts obtained in this way can also be processed further to articles of daily use or jewelry and can also be further processed by rolling, embossing and / or punching.
  • the base metal for applying the lacquer layer can also have prefabricated depressions or perforations and / or a curved starting surface.
  • stepped recesses in the base metal which may have an acid-resistant and non-conductive lacquer layer, can also be used here by means of hand or machine tools for receiving and, if necessary, pre-fixing and fastening decorative parts such as metal parts, stones or the like by means of galvanic edge coating.
  • FIGS. 1 to 3 different manufacturing stages of a method are shown in FIGS. 1 to 3, namely that in FIG. 1 as a partial section in a perspective top view of the base metal, here a noble metal part 1, an acid-resistant and non-conductive lacquer mask 2, with a flat metal surface, e.g. B. applied with a stamp.
  • a noble metal part 1 a noble metal part 1
  • an acid-resistant and non-conductive lacquer mask 2 with a flat metal surface, e.g. B. applied with a stamp.
  • paint-free metal surfaces 3 which can be achieved in a wide variety of shapes.
  • the base metal 1 is shown in section in FIG. 1 a and in FIG. 1 b with an applied resist mask 2 corresponding to FIG. 1.
  • the partial recess in a perspective top view of the precious metal part 1 shows the etching recess 4 after the etching bath on the paint-free metal surfaces 3, and FIG. 2 a shows this in section.
  • the entire metal part 1 with a resist mask 2 is placed in a galvanic noble metal bath, so that the etching recesses 4 according to FIG. B. with fine gold 5 or the like, as is also shown in FIG. 3 a in section with the paint mask 2 removed.
  • the finished piece remains, which can be further processed into a commodity or jewelry object by embossing, rolling and / or stamping or, if appropriate, by hand.
  • FIG. 4 shows a perspective top view of a further finished precious metal part 6 with decor variants 7 in the final state for further processing.
  • FIGS. 5 to 7 different production stages of a further method are shown in FIGS. 5 to 7, specifically in FIG. 5 as a partial cutout in a perspective top view of the base metal, here precious metal part 11, an acid-resistant and non-conductive lacquer mask 12 with a flat metal surface, e.g. B. printed on a paint-free metal surface 13 in the sectional view of Figure 5 a.
  • etching depressions 14 are then made in the paint-free metal surfaces 13 in accordance with FIG. 5 with section FIG. 5 b.
  • new etching recesses 17 that are stepped on the sections 15 of further lacquer masks 16 corresponding to FIG. 6 a in the second etching process can be achieved, as is shown in section 7 a.
  • etching recesses 17 can be used to hold decorative parts 18 made of metal, stone or the like, which are then given a metallic edge covering 19 for final fixing with the lacquer mask 16 after sectioning FIG. 7a after fixation in the galvanic bath, as shown in FIG Show decrease in paint job 16.
  • FIGS. 10, 10 a to 10 e and 11 show different manufacturing stages of a method as a further exemplary embodiment
  • a partial cut-out is a perspective top view of the base metal, here, for example, a platinum strip 31 with, if appropriate, an acid-resistant, non-conductive lacquer layer 32 in the case of a flat surface, depressions, here blind holes 33.
  • FIG. 10 a shows a section through the platinum strip 31 as the starting material, in FIG. 10 b coated with the lacquer layer, in FIG. 10 c recesses 33 are made for this purpose by hand or machine tools (removal tools), which are then placed in a galvanic bath according to FIG.
  • 10 c for example be filled with precious metal 34 and in FIG. 10 e the platinum strip 31 with depressions 33 and precious metal filling 34 is shown after removal of the lacquer layer, and in FIG. 11 the perspective view of how this is the finished piece or starting material for further processing for jewelry or everyday objects.
  • FIGS. 12, 12 a to 12 e and 13 production stages of a further method possibility are then shown as a partial view in perspective top view of the base metal, here also a platinum strip 35 and in FIG. 12 a a section through the platinum strip 35 in FIG. 12 b with recesses 36 incorporated by hand or machine tools, in FIG. 12 c with applied lacquer layer 37 and after the galvanic bath in FIG. 12 d for example filled with precious metal 38 and in FIG. 12 e with removed lacquer layer and in FIG. 13 the perspective view of this.
  • the same result is achieved as in the previously shown embodiment as a finished piece or as a starting material for further processing for jewelry or everyday objects.
  • FIGS. 14 and 14 a a curved base metal body 39 with lacquer layer 40 as the starting form and, in FIGS. 15 and 15 a, a flat base metal strip 41 with lacquer layer 42 are juxtaposed as further exemplary embodiments.
  • the further machining process takes place, for example, according to one of the previously described production stages.
  • FIGS. 16, 16 a and 16 b also show a base metal strip 43 and lacquer layer 44 and, if appropriate, stepped perforation 45, which (45) for receiving a decorative body or stone 46 and possibly pre-fixing it, e.g. B. by means of glue or by means of grains attached grain for locking and fastening by means of galvanically applied edge covering 47 can serve according to the previous statements.
  • FIGS. 17 and 17a finally show a base metal strip 48 as the starting material with a lacquer layer 49 on both sides for double-sided processing, for example by introducing a channel 50 on both sides for further processing in accordance with the first two exemplary embodiments.
