Definitions

  • the invention relates to a device for the thermal spraying of build-up welding materials, Consisting of a jet bundling nozzle with a burner nozzle arranged on the loading side and with devices for controllable supply of the equipment components.
  • the invention is accordingly based on the object of improving the device of the type mentioned in such a way that, in particular, there is no electrical ignition and the circuit required therefor, ie, the device can be ignited in a conventional manner, the risk of an explosion or the Disadvantages of flame extinguishing should be excluded.
  • the nozzle front part of the other part of the beam bundling nozzle simply lift and thus free the nozzle and after igniting and adjusting the flame the nozzle front part again in its Bring operating position.
  • an embodiment is preferred in which the nozzle front part can simply be swiveled down and back into its operating position.
  • the design of the device according to the invention also has the advantage that the respective nozzle front part can easily be used against another nozzle front part, e.g.
  • the other part can be designed to be displaceable with respect to the burner nozzle or the nozzle holder according to EP-A-0135826, that is to say suitable devices must be provided which on the one hand ensure this displaceability and on the other hand have to be designed in such a way that that the other part can not easily detach from the nozzle holder.
  • Interchangeable front parts do not have to have such adapter-like designs, but only ever have corresponding releasable hinge or other connection parts and, on the other hand, corresponding connection surfaces.
  • the "adjustability" and the associated release of the burner nozzle for ignition by hand can also be realized in such a way that the front part is arranged axially adjustable on guides in relation to the other part parallel to the longitudinal axis of the nozzle.
  • at least one guide rod extending axially parallel to the longitudinal axis of the nozzle is sufficient, which is stuck on the other part or on the front part of the nozzle and engages in a correspondingly profiled longitudinal guide of the other part, so that the front part of the nozzle can be adjusted in the longitudinal direction parallel to the longitudinal axis of the nozzle. Since this also requires certain protective measures, the pivotable embodiment is preferred.
  • ne is therefore to be understood by "adjustable" that, with a suitable structural design of the two parts, the nozzle front part can simply be swiveled or pushed away and brought back into the operating position after ignition, since the handling of such a device is thus considerably easier because the front part can be left as guided and possibly still under spring tension, swivel back very quickly into the operating position by reaching through the flame.
  • the structural design with regard to the coolability of the device is not shown. Also not shown are the elements for regulating supply of the operating gases, which are located in a suitable manner on the part of the nozzle holder 6, not shown.
  • the powder to be sprayed on can be supplied in a known manner through a central powder feed channel (not shown) of the nozzle holder 6 or the nozzle 5. However, it is also possible, as will be explained in more detail, to introduce the powder from the outside directly into the opening area of the bundling nozzle channel 3.
  • the nozzle holder 6 can be a flame spray burner of a conventional type, on the cylindrical front part of which the part 1 of the bundling nozzle 7 is then pushed and fixed in a suitable manner in a detachable and axially adjustable manner.
  • the device consists of a beam bundling nozzle 7 with an expanded space on the feed side for receiving devices for controllable supply of the operating components, the expanded space being designed as a combustion chamber 1 with a transition contour 2 for opening into the actual bundling nozzle duct 3 and in the Combustion chamber 1 with respect to the mouth 4 of the beam bundling channel 3, an axially adjustable burner nozzle 5 or a nozzle holder 6 with a nozzle 5 is arranged.
  • the bundling nozzle 7 is divided in the region of the combustion chamber 1 transversely to the longitudinal axis 8 of the nozzle, and the nozzle front part 9 is adjustably arranged with respect to the other part 10 arranged on the nozzle 5 or on the nozzle holder 6.
  • the adjustability is realized by a pivotable assignment of the nozzle front part 9 to the other part 10 and simply in such a way that the other part 10 is provided with a lateral bearing extension 19 and a joint extension 20 thereon which can be designed as a separable joint for the purpose of easy interchangeability.
  • the joint extension 20 of the nozzle front part 9 can expediently be provided with a handle 21, as indicated by dashed lines in FIG.
  • the parting plane can be designed in the form of a step 12, but it can also be designed inclined, as shown in FIG. 2, preferably at 45 ° to 90 ° . If at all necessary, the connection surfaces 14 of both parts 9, 10, as can be seen in FIG. 3, are provided with sealing profiles 15 and / or with a fire-proof seal 16. Such sealing measures would, however, only be required if the most extreme operating position of the nozzle holder 6 in the left position still runs in the area of the parting plane 11.
  • the adjustability of the two parts 9, 10 is realized in such a way that two appropriately profiled guides 13 are fixedly arranged on the part 10 and extend parallel to the longitudinal axis 8 of the nozzle.
  • the nozzle front part 9 is then mounted in a suitable manner, axially parallel, so that, as shown, the nozzle 5 can be kept free by axially adjusting the front part 9 to the front.
  • at least a correspondingly long handle would have to be provided on the front part 9 (not shown).
  • Fig. 5 shows a section of a real embodiment through the bundling nozzle 7, in which corresponding parts are provided with corresponding reference numerals.
  • the actual burner nozzle 5 and the nozzle holder 6, on which this entire attachment is screwed, for example, are not shown.
  • the bundling nozzle 7 is equipped with a cavity 25 for passing a coolant through to be able to cool the nozzle. The line connections required for this are not shown.
  • powder feed nozzles 18 are arranged in the nozzle front part 9 in the connection area to the other part 10, as can be seen in FIG. 6, to which corresponding powder feed lines, but not shown here, lead. This extends the area of use of the device with regard to different powders.
  • injection channels 18 can also be used as supply channels for additional gases, such as air, fuel gases, inert gases, but even for liquid fuels with a high calorific value, and it is also possible, with a sufficient number of channels 18, to provide a part for the powder supply and one Use part for an additional gas supply.
  • additional gases such as air, fuel gases, inert gases, but even for liquid fuels with a high calorific value, and it is also possible, with a sufficient number of channels 18, to provide a part for the powder supply and one Use part for an additional gas supply.
