Definitions

  • the invention relates to a nozzle head according to the preamble of claim 1.
  • Such nozzle heads through which a fluid under high pressure, for example water, with an abrasive substance is added as an additive, for example, as cutting tools use to cut a variety of materials.
  • a fluid under high pressure for example water
  • an abrasive substance for example, as cutting tools use to cut a variety of materials.
  • these nozzle heads are also suitable for the surface treatment of workpieces, primarily for cleaning the surfaces or for their roughening, if this is necessary for a subsequent coating.
  • the abrasive material is admixed laterally with the fluid which, after mixing with the substance, exits the nozzle head in the axial continuation of the feed line.
  • a parallel to the feed line extending inner surface of a hollow body can not be practically processed with the known nozzle heads or only insufficient, since the exiting fluid impinges on this surface only at a relatively acute angle.
  • the invention is therefore based on the object to develop a nozzle head of the generic type so that its usefulness is improved.
  • This design of the nozzle head an extremely compact design is possible, which allows to introduce the nozzle head in the hollow body, which have a relatively small clear diameter, so that the inner surface of the hollow body can be processed easily and effectively.
  • Such a processing represents, for example, the roughening of the surface in order to subsequently coat it, wherein the roughening results in a particularly intensive bonding of the coating to the carrier surface.
  • the supply line for the fluid under high pressure starting from an axial orientation in a right angle or almost right angle extending outlet line passes, in the latter case, the angle in a range of 60 ° to 120 °, which has a mixing chamber in which the abrasive substance is admixed, that is, the abrasive material leading channel opens into this mixing chamber.
  • the nozzle head be formed in two parts, the two adjoining parting surfaces extending in the axial direction of the feed line or the channel.
  • the supply line for the fluid and in the other component of the channel provided, while the discharge line extends transversely thereto in both components.
  • the fluid acted upon by the abrasive substance hits the surface to be processed perpendicularly, resulting in a high efficiency, since the particles of the abrasive substance are not deflected.
  • the invention enables a problem-free machining of workpieces in the aforementioned sense, as previously possible only with a considerable expenditure on equipment and time. In fact, it is now also possible to work on workpieces that were previously not workable in this form.
  • a nozzle head which consists of two parts, namely a first component 1 and a second component. 2
  • the first component 1 has a feed line 3 for a fluid which can be supplied from an assembly and is under high pressure, which is designed as a blind hole and from which a branch 5 'laterally branches off in the region of the base.
  • the second component 2 is provided with a channel 4 through which an abrasive material is supplied to the fluid, said channel 4 extending parallel or nearly parallel ( ⁇ 30 °) to the feed line 3.
  • the feed openings are arranged on the adjacent end faces of the first and second component 1, 2.
  • Both components 1, 2 are located on axially parallel to the supply line 3 and the channel 4 aligned separating surfaces 15 to each other and are connected by screws 6 firmly together.
  • the branch 5 opens into a recess 12, which is provided both in the first component 1 as well as in the second component 2 and in which a nozzle body 9 is mounted, which receives a nozzle plate 10 with an enclosed high-pressure nozzle 11, wherein the nozzle plate 10 at the bottom the recess 12 associated with the first component 1 and the nozzle body 9 bear against the base of the recess 12 associated with the second component 2, which thereby form a sealing surface, that the nozzle body 9 or the nozzle disk 10 are firmly clamped by means of the screws 6.
  • the nozzle openings of the nozzle body 9, the nozzle disk 10 and the high-pressure nozzle 11 provided in continuation of the branch 5 'lead into a mixing chamber 7 in the second component 2, which is supplied with the abrasive substance via the channel 4 in the sense of an injector nozzle.
  • This mixing chamber 7 passes into a discharge line 5, from which the mixture fluid / abrasive material for processing the surface, for example, the inner surface of a dash-dotted line in the figure hollow body 14, at an angle to the supply line 3 extending laterally from the nozzle head and the second Component 2 exits.
  • the discharge line 5 is inserted into an insert 8, which is held by a clamping screw 13 in the second component 2.
  • the nozzle head can be moved axially back and forth during operation, while the workpiece, that is to say the hollow body 14, is rotatable about the nozzle head.
  • the workpiece can also be moved axially back and forth.
  • a rotational movement of the nozzle head is conceivable. In any case, a uniform machining of the entire surface of the workpiece is achieved by the axial and rotational movement.
