Definitions

  • the invention relates to a frame for holding workpieces in a galvanic bath according to the preamble of Claim 1.
  • Such racks serve, preferably several workpieces during a galvanic coating process to hold in the galvanic bath.
  • the frame is doing so with the holding device in an electrically conductive manner energized goods rod attached, which over the galvanic bath stretches.
  • the holding device can be in the manner of a screw clamp be formed, which is clamped to the goods rod becomes. This will make a flawless contact point achieved, but putting on and putting on requires Screw clamps take a considerable amount of time.
  • the form-fitting in a corresponding counter bearing on the goods bar can be hung.
  • This holding device can be very be served quickly, but is already a minor Tilting of the contact surfaces is sufficient electrical Line no longer guaranteed.
  • at certain workpieces have so much buoyancy in the bathroom, that the dovetail is lifted out of the counter bearing.
  • the resilient clamping bracket presses the rack with his Contact surface against the goods rod, being a relatively large area Contact is made.
  • Spring characteristics can achieve high lateral stability become. Rubs into the goods bar when the frame snaps into place the contact area until the end position is reached at the Goods bar. The same process takes place when solving the Frame again. By rubbing the surfaces occurs a self-cleaning effect, which is in the aggressive atmosphere of the galvanic bath Oxide layers can be removed again and again.
  • the spring travel of the clamping bracket is particularly advantageous limited a limiting element that attaches to the frame shaft is on the side facing away from the contact surface Outside of the clamp on this attack.
  • Limiting element can the spring behavior of the clamp be influenced so that in its end position with high strength and contact pressure on the goods rod.
  • the limiting element is preferably a bracket that includes the clamp and the articulated on the frame shaft is stored. Due to the articulated mounting, the bracket can the movement of the clamp to a certain extent comprehend.
  • the clamping bracket can be made particularly easily from tape material, for example made of a chrome steel. His electrical conductivity is of secondary importance Meaning. However, it is important to have sufficient Spring properties and a certain corrosion resistance.
  • the clamp bracket is advantageous with the frame shaft screwed. The latter usually consists of Aluminum, brass or copper, which is a welded joint considerably more difficult.
  • FIG. 1 and 2 is on a in Cross section rectangular frame shaft 4 made of aluminum, Brass or copper at the upper end of a holding device 5 arranged.
  • This essentially consists of a clamp 8, for example made of chrome steel, which has good spring properties having.
  • the clamp is on one side by means of Screws 15 connected to the frame shaft, which in Threaded bores 16 are screwed in.
  • the clamp has a curvature 13, which the end of the frame shaft 4th spreads. Instead of a single curvature, too several curves with straight sections in between be provided.
  • the resilient free end 9 of the clamping bracket lies at a distance from a contact surface 7 Frame 4. The free end can against the spring force in Arrow direction b can be swung open.
  • the curvature is 13 formed such that the free end 9 is also fully stretched Condition only on a linear support area 14 rests on a surface parallel to the contact surface 7.
  • the clamping bracket 8 is angled 12 provided, which facilitates the pushing onto a goods rod.
  • a bracket 10 is arranged, which is approximately the shape of a chain link and which comprises the clamping bracket 8.
  • the bracket 10 is in a bore 11 on the frame shaft articulated and can be swung up in the direction of arrow a become.
  • the bracket could can also be replaced by another limiting element, the the opening movement of the clamp 8 in any way limited.
  • Spring travel also possible through the arrangement of the screws 15. The shorter the clamp bracket 8 relative to the upper end of the frame shaft is summarized, the shorter the travel.
  • the described rack is attached to a Goods rod 6 connected, which is also a rectangular Has cross section and for example made of copper or consists of a copper alloy.
  • a Goods rod 6 which is also a rectangular Has cross section and for example made of copper or consists of a copper alloy.
  • Figure 4 shows the overall representation of a frame 1 with a single frame 4, on which by means of suitable Holding devices workpieces 2 are attached on both sides.
  • the rack is by means of those described above Holding device 5 attached to the goods rod 6.
  • the workpieces 2 are immersed in a galvanic bath 3.
  • the frame 1 could also have several frame shafts have, which are interconnected.
  • the limiting element for the clamp to leave out entirely.
  • the spring characteristic of the clamp are designed such that the Spring force increases progressively.
