Definitions

  • the invention relates to a contact tip for welding and cutting torches with one or more inner openings for guiding and contacting one or more welding wires.
  • Inert gas welding torch fastens and guides the welding wire to the point at which the arc begins.
  • the relatively high welding current is fed to the welding wire via the contact tip.
  • the contact tip is therefore exposed to high loads due to the current flow and the thermal stress, so that previously drawn copper material has been used for its production, with electrolyte-copper and copper-chromium-zirconium being used as the hollow semi-finished material.
  • the manufacturing means and equipment as well as the manufacturing process itself for these drawn materials are very complex, so that there are only a few suppliers on the market, which is reflected in the corresponding material costs.
  • Another disadvantage is that special designs are required for each special nominal diameter and for each tolerance zone. This is particularly disadvantageous for small quantities.
  • a major disadvantage of drawn material is above all the change in material properties due to heat treatment and forming.
  • the structure and wear properties of the inner opening are negatively influenced by the change in structure as a result of the heat treatment and the forming processes. Proceeding from this, the object of the invention is to propose a contact tip for welding and cutting torches which can be manufactured much more cost-effectively.
  • Deep drilling is characterized by the use of tools that allow lubricant and drilling fluid to be fed into the drill tip and to force the chips to be removed. Deep drilling also works at a high drilling speed, i.e. Small chip dimensions are generated, which allow continuous drilling thanks to constant chip removal.
  • alloys with a greater degree of freedom with regard to the microstructure, the heat treatment, the forming history or the material history.
  • a material can be selected that is optimal with regard to wear resistance and power transmission.
  • materials or semi-finished products can now be used that could not be processed with the previous manufacturing process (drawing process).
  • the alloys which are now available according to the invention no longer have to be drawable in this semi-finished form. Alloys can now be used for contact tips that were not previously suitable for this purpose.
  • the properties of the semifinished product are not significantly influenced by deep drilling, so that these properties are or remain predictable or predeterminable.
  • Another advantage is the surface quality achieved in one work step and the improved tolerance. This improved tolerance means that there is a defined current transition during welding over the entire area of the contact tip and that a much better mechanical guidance is achieved, which in turn leads to less electrical, thermal and ultimately mechanical wear.
  • Such a contact tip is preferably produced by clamping a rod-shaped or rod-shaped material of a desired alloy and a desired outer diameter in a deep-drilling machine known per se and then producing one or more inner openings from the primary material by deep drilling. Deep drilling simultaneously creates an inner surface of high accuracy, the coefficient of friction of which is absolutely predictable compared to the welding wire and is not subject to fluctuations.
  • Figure 2 shows a deep drilling machine
  • the contact tip 1 according to FIG. 1 is, as is customary as a rule, cylindrical in shape, and the tip can be made somewhat tapered.
  • a thread is provided in the rear area with which the contact tip is fitted into the welding or cutting torch.
  • the contact tip has a continuous inner opening 2, which has a chamfer on its rear side, so that the welding wire can shrink better.
  • Such welding nozzles are state of the art in terms of shape.
  • the inner opening 2 was produced by deep drilling from a semi-finished product made of solid material or of tubular material. Compared to the previous drawing of pipes or parts that were already hollow, this allows a much larger selection of materials.
  • FIG. 2 shows schematically a deep drilling machine 3, the essential components of which are the drive 4, the drill 5, the clamping device 6 and the feed 7.
  • the function is selected in this embodiment so that the workpiece, in this case the contact tip 1, is fixed upright while the tool or drill 5 is rotating.
  • This is the standard version for deep drilling for rotary and asymmetrical workpieces.
  • the drill 5, which is rotated by the drive 4 is slowly pushed into the contact nozzle 1 via the feed 7 and thereby creates the inner opening 2.
  • the devices for rinsing the drill tip and for removing the chips, which are customary in deep drilling, are not shown. Since a rotationally symmetrical workpiece is machined, it is also possible to use deep drilling machines in which the tool, that is to say the drill 5 and the workpiece or the current nozzle 1, rotate in opposite directions. The mode of operation is also possible, in which a rotating workpiece is provided while the tool is stationary.
