Definitions

  • the invention relates to a method and an apparatus for galvanizing sheet metal surfaces according to the preambles of claims 1 and 2.
  • the object of the invention is to provide a method and a hand-held device for post-galvanizing, the device for performing the method being designed to be easy to handle and compact in order to carry out post-galvanizing in a simple manner even on shaped metal sheets in a strip production of motor vehicles to be able to take.
  • the galvanizing should be constructed in such a way that subsequent stove enamelling is possible without post-treatment.
  • the advantages achieved by the invention are essentially to be seen in the fact that the post-galvanizing process is to be carried out with an easy-to-use working device, with which the oscillating element works quickly due to its own movement. In addition to the self-movement, a free movement of the handheld device is possible.
  • the device must also be used to clean the surface before galvanizing. For this purpose, only the processing element for galvanizing is exchanged for a processing element for cleaning, or two devices with the corresponding processing elements are used.
  • the longitudinal and transverse grooves arranged in the working surface of the processing element preferably extend over the entire surface, so that a uniform delivery of zinc electrolyte to the coating is ensured.
  • a peristaltic pump provided in the feed line enables an optimally metered delivery of the zinc electrolyte into the coating, so that the amount of liquid required for galvanizing is always available.
  • a metering valve that interacts with the pump would also be possible.
  • the procedure is coordinated so that the post-galvanizing layer is flush with the existing zinc layer and is constructed in such a way that further treatment of the sheets by baking is possible without bubbles or other unevenness on the painted sheet surface.
  • Fig. 1 the structure of the method for galvanizing with a handheld device 1 is shown schematically.
  • Zinc electrolyte is supplied to an absorbent coating 2, a so-called tampon, which is held on a processing element 3 and is absorbed by the tampon.
  • the processing element 3 can consist of graphite or platinized titanium and forms an anode, the material 5 to be galvanized being designed as a cathode.
  • the process is carried out at a voltage of 11 to 13 V and with a current of 10 to 15 A.
  • the surface of the sheet is cleaned using an aqueous alkaline solution with a pH of around 13.
  • the zinc electrolyte is based on an alkaline base and has a pH of around 8.
  • a zinc layer with a thickness of 8 to 12 ⁇ m is achieved in about 2 to 3 minutes.
  • the average layer thickness produced in this way can be assessed by an ampere-hour counter during application and a corresponding signal is generated after the desired layer thickness has been reached.
  • the hand-held device 1 for carrying out the method essentially consists of the lower processing element 3 and an upper, manageable tool 7, which is detachably connected to the latter, and in which an oscillating part is integrated.
  • the oscillating part sets the hand-held device in an automatically reciprocating movement on the workpiece 5.
  • the hand-held device 1 can also be freely moved in any direction.
  • the zinc electrolyte is supplied to the absorbent coating 2 via bores 8 which open into longitudinal and transverse grooves 9, 10 which are open towards the coating 2.
  • the working surface 11 of the machining element 3 is adapted to the shape of the sheet 5, so that the area of the weld seam 12 with the element 3 is easily accessible.
  • the shape shown is only an example, any other shape is also conceivable, for which purpose the processing element 3 must then be adapted accordingly.
  • the galvanizing plant essentially comprises a line 13 for the zinc electrolyte, a peristaltic pump 14 and an upstream filter regeneration element 4.
  • the method for galvanizing is carried out in such a way that the ground surfaces around the weld seam 12 are electrically cleaned, the hand-held device 1 likewise having a tampon to which a cleaning solution is fed.
  • the galvanizing is then carried out by moving the hand tool 1 over the ground surfaces with a slight pressure while supplying zinc electrolyte.
  • the coating 2 stampon
  • the pump 14 is switched on via a relay 17 and the electrolyte circuit 13 is started up to the hand-held device 1.
  • the line circuits are shown only schematically. After a deposition process, the ground surface is galvanized and flush with the rest of the zinc layer. This is followed by painting the sheet surface without post-treatment of the zinc layer.
