  • Similar devices of this type, in which the straightening units are always firmly connected to the device for generating the material jet are also known from US 5,664,992, DD 294 891 A5 and US 2,439,032.
  • the problem is often the use of such devices in the range of Bore intersections, where due to the rigid at the top of the devices for Generation of the material beam arranged straightening units, for example, to spatial Problems may arise in the area of bore intersections, which may be the use of the restrict known devices.
  • the object of the invention is a method to provide a problem-free removal of material inside a Workpiece in the area of Bohrverschneidungen allows. This task will solved in the method according to claim 1.
  • the spatial Separation between the beam generating unit and the straightening unit becomes essential better accessibility or flexibility of the device used in the range of Botuungsverschneidonne achieved by the fact that the two units in different Holes are introduced and so on different areas of Bohrungsverschneidung can be arranged.
  • suitable device and advantageous developments of this Device are listed in claims 3 to 8.
  • Figure 1 is schematically a not affected by the scope Injector jet device shown, wherein a Water jet 1 an abrasive 2 in a mixing chamber. 5 sucks, so that a mixed jet 3 generated in a probe 6 becomes. From the probe 6 exits a stream of material 4, the by means of a reflection element 7 to a predetermined Area is directed inside a workpiece 8.
  • a relatively hard to reach area e.g. as a hole 9
  • a relatively small Diameter example has a few millimeters.
  • the device is movable according to an arrow P 1 in the axial direction of the probe 6.
  • the device according to an arrow P 2 is rotatable about the axis of the probe 6. This makes it possible that almost arbitrarily formed areas in the interior of the workpiece 8 can be removed.
  • a control unit not shown, controls the movement of the device for this purpose.
  • annular cavity of the bore 9 can be generated by rotation in accordance with arrow P 2 .
  • the bore 9 may be in contrast to the illustrated variant, a blind hole.
  • FIG. 2 shows a device according to the invention shown, in contrast to the device according to FIG. 1 no holding element 11 fixed to the probe 6 is provided, but a separate baffle plate 12, the introduced through a second bore 13 in the workpiece 8 is.
  • the workpiece 8 according to FIG. 2 is for example, a so-called rail (pressure accumulator) the system common rail.
  • the rail 8 includes in particular Branches 14, each having a bore 15. in the Generally, both the bore 13 and the Bores 15 produced by machining, so that in the transition area between the holes 13, 15 burrs or sharp edges arise.
  • the probe 6 in the bore 15th introduced and the baffle plate 12 in the bore 13, so that the substance jet 4 is reflected on the baffle plate 12 in such a way is that this the transition area in exactly predetermined Deburred or rounded off.
  • This is especially positive, that by the impulse effect of the material jet 4 on impact on the workpiece 8 a compaction of the structure and thus Compressive stresses of the workpiece 8 are generated.
  • Compressive stresses have an advantageous effect on the later Application of the rail 8, this particular one pulsating load at comparatively high pressures is exposed.
  • Figure 3 are differently shaped baffles 12th shown schematically.
  • Figure 3a has both a 39als also a front view of a baffle plate 12 with planar, perpendicular to the material beam 4 aligned reflection surface 16 on.
  • the baffle plate 12 according to Figure 3a corresponds largely the baffle plate 12 according to FIG. 2
  • the baffle plate 12 according to Figure 3b is again in side than Also shown front view and has a planar Reflection surface 16, but this angle to the Beam direction of the fabric jet 4 is arranged.
  • FIG. 3c shows a side and front view of a baffle plate 12 with a plurality of planar reflection surfaces 16 oriented perpendicular to the material jet 4.
  • the baffle plate 12 according to FIG. 3 c can optionally be rotated about the longitudinal axis according to arrow P 4 so that the baffle plate 12 can be rotated and / or displaced along the arrow P 3 in the region of the impinging substance jet 4, for example ,
  • FIG 3d is a section of a baffle plate 12 with a parabolic reflective surfaces 16 shown.

  • the baffle plate 12 more longitudinal grooves 17 and a plurality of recesses 18th so that numerous impact areas on the Impact plate 12 can be realized.
  • FIG 4 is a baffle plate 12 with a blind hole-like Well represented.
  • the blind hole-like depression, the optionally also formed as a longitudinal groove 17 can, has the reflection surface 16.
  • the fabric jet 4 is such reflects that of the transition region of the bore 13 and the bore 15 ablates in a predetermined manner.
  • FIG. 5 shows a baffle plate 12 having a plurality of, in particular longitudinal grooves 17, wherein due to the rotationally symmetrical design, the baffle plate 12 can be rotated as needed according to arrow P 4 , so that another groove 17, the transition region of the bore 13 and the bore 15 removes.
  • the baffle plate 12 can be designed such that a machining sequence can be provided by turning the baffle plate 12 according to the arrow P 4 .
