Definitions
- the invention relates to a modular abrasive water jet cutting head with targeted addition of abrasive.
- the cutting jet is covered with a water jacket (DE-OS 4005691).
- a water jacket DE-OS 4005691
- a cutting beam evenly loaded with abrasive particles is a requirement for a clean, even cut.
- the one-sided uneven distribution of the particles in the mixing chamber and the thus untargeted supply of particles to the circumference of the water jet flowing through the mixing chamber centrally of the cutting heads described above there is no uniform particle jet as is desired.
- An asymmetrically loaded mixed jet can cause an uneven cut and wear on one side of the focusing nozzle.
- the purpose and object of the invention is to apply abrasive particles to the surface of the cutting beam in the respective cutting direction in order to increase the cutting performance while reducing the use of abrasive.
- the knowledge that only the abrasive particles located on the surface of the cutting beam in the cutting direction take effect means that the previously known mixing chamber is filled with a metering insert, the bore of which is the passage of the cutting beam, to which a line nestles laterally . From this widening, at a ratio of the diameter of the abrasive particles to that of the cutting jet of approximately 1: 4, abrasive particles are applied to the surface of the cutting jet in a track from 30 ° to 60 ° wide. By rotating the cutting head or the dosing insert about the axis of the cutting beam according to the cutting parameters, the track covered with abrasive agent emerges from the focusing nozzle on the side of the cutting beam facing the cutting direction.
- the angle of rotation for the cutting head can be reduced or the Cutting head can be rigidly attached.
- the modular abrasive water jet cutting head there is an adjustment element with which an adjustment of these parts is carried out individually and / or completely to ensure the alignment of the jet-guiding elements and thus to ensure collimation of the jet-forming head components.
- FIG. 1 shows a longitudinal section through a modular cutting head in principle
- Fig. 2 shows a metering insert in longitudinal section
- Fig. 3 shows a metering insert in cross section
- a modular cutting head 1 is connected to a collimation tube 2 with a high-pressure connection 3.
- a nozzle block 4 stands in front of the end of the collimation tube 2. Starting from the nozzle block 4, the entire modular cutting head 1 runs through a central channel 6 along its central axis 5.
- the modular cutting head 1 is encased by a housing 7, which is closed off by a focusing nozzle holder 8 is.
- the modular cutting head 1 is held by screws 9.
- a mixing chamber 10 which contains a metering insert 12 provided with an expansion 11.
- the dosing insert 12 is positioned in the mixing chamber 10 with a spacer 13.
- An abrasive feed line 14 opens laterally into the mixing chamber 10.
- the widening 11 is located in front of the abrasive feed line 14.
- the focusing chamber 15 is followed by a focusing nozzle 15 held by the focusing nozzle holder 8 in the axial direction of the modular cutting head 1.
- a high-speed water jet 16 generated by the nozzle stone 4 flows in the axial direction along the central axis 5 through the modular cutting head 1 in the central channel 6.
- a trace of abrasive is applied to a jacket section of the high-speed water jet 16.
- the bore 18 in the middle of the dosing insert 12, which is fixed by means of a groove 17.
- the bore 18 has a diameter approximately equal to the strength of the high speed water jet 16.
- the wall of the bore 18 is cut open by the widening 11.
- the abrasive is only applied to the jacket section of the high-speed water jet 16 located in front of the expansion 11.
- the modular cutting head 1 is rotated so that at the exit of the Focusing nozzle 15 always leaves the trace of the abrasive on the side of the high-speed water jet 16 located in the cutting direction.
