Definitions

  • the invention relates to a device for the surface coating of metallic or non-metallic workpieces with process solutions containing ions, in particular electroplating with an electrolyte is tightly pressed, and the container has an anode in its interior, while the workpiece and in particular its surface in contact with the electrolyte forms the cathode.
  • the surface of the workpiece delimited by the opening of the container can be galvanically processed and thereby provided with a coating.
  • the coating takes place essentially over the entire surface that is covered by the opening of the container. After-treatment of small damaged areas of the surface coating is therefore carried out in addition to filling the damaged surface coating also a relatively large-area metal application on the adjacent, undamaged surface areas of the workpiece, so that extensive post-processing by removing the excess thickness of the coating is required.
  • the invention has for its object to provide a device of the type described above, with which parts of the surface of a workpiece can be provided with a metallic surface layer and, in particular, damaged areas of a metallic surface coating can be reworked, the metal application in particular at predetermined locations within that of the Opening of the container covered surface of the workpiece takes place.
  • the anode provided in the interior of the container with a spherical configuration of its end face or the like to form a smooth-walled depression by grinding.
  • the end face of the anode is due to its dimensions and the spherical design in shape and size of the to a smooth-walled trough by grinding or the like.
  • Elaborated, damaged area adjusted so that the streamline distribution is precisely aligned.
  • This predetermined streamline distribution ensures that the like to a smooth-walled trough by grinding. worked out, damaged area is filled in, while on the neighboring parts of the surface of the workpiece there is little or almost no metal application. After finishing the surface coating on the damaged area, only slight excess thicknesses of the coating have to be removed.
  • the device is used for surface coating, such as electroplating, in particular after-treatment of damaged surfaces of metallic or non-metallic workpieces with process solutions containing ions, such as an electrolyte.
  • a metallic roller 10 which is provided with a metallic surface coating 11, is aftertreated, since the surface coating 11 has a damaged area.
  • the aftertreatment is carried out galvanically with an electrolyte 13.
  • the roller 10 to be treated is pressed tightly against a container receiving the electrolyte 13 with a peripheral edge 15 of an opening allowing the electrolyte 13 to be treated on the surface of the roller 10 to be treated.
  • the pressing of the container 14 against the roller 10 can or the like in a known manner with a bandage. take place and is not shown for the sake of simplicity.
  • the peripheral edge 15 of the container opening is pressed against the surface of the workpiece 10 with a seal 16 made of flexible material such as rubber, plastic or the like, so that the electrolyte 13 is secured against leakage.
  • the container 14 to be pressed against the surface of the roller 10 and holding the electrolyte 13 consists of a material which is resistant to the electrolyte 13, such as titanium, plastic or the like.
  • the container 14 is provided with an inlet opening 17 and an outlet opening 18 so that the electrolyte can flow in a circuit through the container 14.
  • a pump 20 is provided in the inlet pipe 19.
  • the electrolyte 13 flowing through the container 14 comes from a storage container 21 and flows back to the latter.
  • the gases generated during electroplating also reach the storage container and can escape from it.
  • the container 14 can be made relatively small in a simple manner, and a sufficient amount of electrolyte is nevertheless available, since the electrolyte comes from a relatively large storage container 21 and flows back to the latter.
  • the container 14 can thus also for repairs in difficult to access places of devices, equipment or the like. be used because it takes up little space.
  • the electrolyte can also be refreshed and / or heated in the storage container 21.
  • the heated electrolyte can also be used to heat the workpiece 10 to be treated, in particular at the damaged area 12.
  • an anode 23 is arranged in the interior 22 of the container 14, while the roller 10 and in particular its surface in contact with the electrolyte 13 forms the cathode.
  • Anode 23 and the roller 10, which acts as cathode, are connected to a power generator 24.
  • the damaged area 12 becomes a smooth-walled depression 25 by grinding or the like. to work out.
  • the anode 23 provided in the interior 22 of the container 14 is adapted with a spherical configuration on the end face of the trough 25 facing the damaged area 12. This spherical, in particular spherical design of the anode results in a streamline distribution adapted to the trough 25.
  • the anode 23 is essentially perpendicular to the damaged area 12.
  • the embodiment shown is merely an example of realizing the invention and it is not restricted thereto. Rather, many other designs and applications are possible.
  • the housing 14 could also be used to flow a cleaning liquid to clean and degrease the damaged area before treatment.
  • the like at the damaged point by grinding or the like. be worked out, smooth-walled trough in their shape and size of the shape and size of the anode are adapted.
