Definitions

  • the present invention relates to a device for collecting the liquid jet of a liquid jet cutting machine.
  • Such liquid jet cutting machines are known and are suitable for cutting a wide variety of materials, water being mostly used as the cutting liquid.
  • the liquid jet flows out of a nozzle with a pressure of up to 4000 bar and allows the contact-free cutting of workpieces made of polystyrene, plasterboard, wood, non-woven fabric, leather, rubber, textiles etc.
  • abrasives such as quartz sand, glass dust, corundum etc. are added to the cutting fluid.
  • the radiation-shaped separation medium is directed onto the workpiece surface and the discharge nozzle is usually guided by means of a CAD control.
  • the jet cuts through the material and emerges from the back of the same. Since the beam still has a very high residual energy even after it has left the cut material, it is essential to absorb it.
  • the object of the present invention is to propose a light and very effective collecting device which is nevertheless robust and resistant and is not damaged or even destroyed by liquid jets which contain abrasive agents. Furthermore, the collecting device should also enable the cutting fluid and the abrasive to be collected easily and simply for reuse.
  • a grate structure with an uneven surface arranged in a trough which preferably has grooves or channels running parallel to one another, forms a very resistant baffle surface on which the liquid jet always strikes at an oblique angle, so that the baffle surface is already protected by this design becomes.
  • a protective covering made of ceramic plates increases the resistance of the grate construction, and the arrangement of passage points facilitates and ensures the collection of the cutting medium, which can be recycled.
  • the proposed device not only enables dry cutting, but also cutting under water, which can mostly be carried out largely silently. Furthermore, when cutting underwater, the cutting quality of many objects is improved and the generation of dust is suppressed.
  • the device has a tub 1, in which a grate structure 3 is installed above the tub bottom 2.
  • the grate structure 3 has an uneven surface which comprises grooves or channels 9 running parallel to one another.
  • the grate structure 3 is composed of a number of strips 4 and 5, all of which extend in mutually parallel directions, but lie in different planes. Two adjacent strips 4 and 5 are always in two planes which form an angle with one another, so that in the longitudinal direction of strips 4 and 5, channels or channels 9 are formed.
  • the strips 4 and 5 are expediently formed from a perforated plate which can be processed by means of a sheet metal processing machine, e.g. with the help of a bending press, was brought into the form described.
  • the strips 4 and 5 are provided with a covering, appropriately sized ceramic plates 6 and 7 are used, which cover the strips 4 and 5 such that a passage 8 remains between two abutting ceramic plates.
  • the strips 4 and 5 or the ceramic plates 6 and 7 delimit the above-mentioned channels or channels 9, which are expediently provided with gravel or with a glass filling 10.
  • the actual cutting device 3 consists of a known, only strictly schematically indicated liquid jet cutting machine 13, which is arranged on a support device 14 adjustable in at least two directions.
  • the grating structure 3 formed from the perforated plates is never directly exposed to the cutting beam 15, in that the cutting beam never strikes the grating structure at a right angle, so that it is not subjected to great stress and cannot be damaged.
  • the gravel or glass filling further weakens the effect of the cutting jet on the wall of the tub. It is thus possible to work with very high pressure and with abrasives, the water jet losing a large part of its energy in contact with the gravel or glass filling 10 and then escaping through the passage points 8 and the perforated plates into the tub 1, where the Cutting fluid and the abrasive can be collected for reuse.
  • the tub 1 is filled with water to such an extent that the grate structure 3 together with ceramic plates 6 and 7 and together with the gravel or glass filling 10 are under water. It is also possible to arrange the grid 11 together with the workpiece 12 below the water level and to carry out the cutting entirely under water. This has the great advantage that cutting can be carried out with little noise and the cutting quality of many objects is improved. Dust generation is also prevented.
  • underwater cutting cannot be used for every material and in particular porous materials cannot be cut under water.
  • the water When cutting dry, the water is drained continuously, if necessary treated and recycled.
