Definitions

  • the invention relates to a galvanizing device at least one now cell, through which one to galvanizing workpiece, e.g. a brake line or the like, is passed through with an in Direction of transport arranged after the cell Contact zone and at least one of the cells from the Contact zone separating bulkhead, as well as a workpiece surrounding seal, which is between the bulkhead and the Jetzelle is arranged.
  • one to galvanizing workpiece e.g. a brake line or the like
  • Electroplating is used in electroplating Liquids (electrolytes) in which the workpieces immersed and in which they are covered with a metal be coated.
  • Aqueous, acidic are used as electrolytes or alkaline solutions.
  • the anodes are there mostly from the metal to be deposited.
  • For galvanizing from e.g. A zinc electrolyte is used in steel. you dips the workpiece into the electrolyte and applies it the negative pole (cathode) of a DC voltage. additionally you dip a dissolving zinc anode (positive pole) into it Bath. They separate under the influence of the DC voltage split salt molecules depending on their charge.
  • the positive zinc ions migrate to the negative pole, the Workpiece, and are deposited there.
  • the invention is therefore based on the object Galvanizer to provide less Electrolyte is carried over and the service life of the Sealing is larger.
  • the pre-bulkhead serves as a holder for a seal.
  • a pre-seal is attached to the pre-bulkhead is attached or held by the bulkhead.
  • a dynamic pressure is formed in the bulkhead which slows down the electrolyte current leaving the cell.
  • the sealing of a wiper plate is preferred formed, which, however, since it is attached to the pre-bulkhead, is not subject to wear as it is the galvanized pipe not touched.
  • the opening in the scraper plate can be chosen that only a small gap to the Workpiece remains so that almost all of the electrolyte is stripped. A carryover of electrolyte into the This reduces the contact zone to a minimum.
  • FIG. 1 A total of three jet cells 10 can be seen in FIG. 1, which are arranged in an electroplating tub 12.
  • the Now cells 10 are under high pressure from one Zinc electrolyte 14 flows through. It also runs through everyone Now cell 10 is a workpiece 16, namely a brake line 18.
  • This brake line 18 is in a contact zone 20 in electrical contact with schematically shown cathodes 22, which are cooled by means of cooling water 24. Furthermore, in 1 shows a first bulkhead 26 and a second bulkhead 28 recognizable which the electroplating tub 12 from the contact zone 20 separate. Through the bulkheads a carryover of Zinc electrolyte 14 avoided in the contact zone 20.
  • FIG. 2 which shows section II according to FIG shows enlarged view
  • the output 30 is the Now cell 10 can be seen, on which a pre-bulkhead 32 is attached.
  • the pre-bulkhead 32 generates a dynamic pressure for the zinc electrolyte 14 leaving the outlet 30, the thereby being slowed down.
  • the pre-bulkhead 32 also serves as a holder for a total of 34 Seal, which is formed by a stripper plate 36.
  • This scraper plate 36 has an opening that is slightly larger than the outer contour of the brake line 18, so that adhering to the outer circumference of the brake line 18 Zinc electrolyte 14 is stripped without contact.
  • the Brake line 18 is thus free of zinc electrolyte 14. Da the brake line 18 electrolyte-free in the first and that second bulkhead 26 and 28 arrives, no zinc electrolyte 14 are dragged into the contact zone 20.
  • FIG 3 is a perspective view Vorschott 32 shown as it is at the exit 30 of the Jetzelle 10 is used.
  • the pre-bulkhead 32 has essentially a cubic bowl shape, with one side is missing.
  • Two adjacent side walls 38 and 40 are provided with cutouts 42 and 44, the one for the Attaching the ballast 32 to the outlet 30 of the jet cell 10 serve, on the other hand for the passage of the brake line 18.
  • the cutout 44 is open on the edge, so that Advance block 32 snapped onto output 30 without any problems can be.
  • the cutout 42 is essentially slit-shaped, so that the bulkhead 32 over the Brake line 18 can be pushed over.
  • the width of the Slit is slightly larger than the outside diameter the brake line 18, so that entrained electrolyte 14 is largely withheld.
  • On the inside of the The side wall 38 has the stripping plate 36, which is held in position by the electrolyte level pressure.
