Definitions

  • the present invention relates to a method for dismantling a workpiece according to the preamble of claim 1 and to a device for carrying out the method.
  • Separating and cutting devices which operate contactlessly by means of a liquid, gas or laser beam, which beam is directed against the workpiece to be cut.
  • the best known are the water cutting machines, which work with a pressure of up to 4000 bar and enable workpieces to be cut from a wide variety of materials. Workpieces made from polystyrene, plasterboard, wood, nonwovens, leather, rubber, textiles etc. can be cut.
  • abrasive such as e.g. Add quartz sand, glass dust, corundum, etc. and cut harder materials such as metal, glass and stone in this way.
  • the radiation-shaped separation medium is directed exactly perpendicular to the workpiece surface, this vertical position being maintained during the entire separation process, even if the radiation-shaped separation medium is guided by a CAD control.
  • the separation medium is not directed vertically on the surface of the workpiece, but rather deviates from the vertical. If the surface to be cut is not flat but curved, the direction of the separation medium should deviate from the vertical to the tangential plane of the curved surface, during the entire separation process, which e.g. is controlled by CAD. The deviation should be approx. 0.2 to 0.3, whereby the cheapest deviation can also be specified empirically, taking into account the material to be cut and the separation medium.
  • a device as defined in claim 3 is suitable for carrying out the proposed method.
  • the plate 1 serving as a workpiece according to FIG. 1 has a flat surface 6.
  • a separation medium e.g. a water jet 9 directed from the nozzle 10 against the flat surface 6 so that the jet direction deviates from the vertical and includes an angle 11 with the horizontal which is less than 90 °.
  • This deviation from the vertical should be only 0.2-0.3 °, which deviation is sufficient to achieve a perfectly flat and perpendicular cut to the surface 6, even while maintaining the greatest possible cutting speed, which is caused by the separation medium, by the Material of the workpiece as well as the complexity of the cut shape. This deviation is maintained throughout the separation process.
  • the beam direction with respect to the tangential plane is determined, which is intended at the relevant point on the workpiece surface.
  • the direction of the beam will therefore deviate from the perpendicular to the tangential plane by 0.2 - 0.3, this deviation being maintained throughout the separation process.
  • a device is used to carry out the proposed method, which is shown diagrammatically in FIG. 3 and viewed from above in FIG. 4.
  • the device has a pyramid-shaped holder 12 designed as a cage, which consists of an upper, square frame 13, a similar smaller frame 14 and connecting rods 15 which run obliquely from top to bottom.
  • the upper frame 13 consists of two mutually parallel struts 16 ', 16 “and 17', 17", the struts 16 'and 16 "being provided with a guide 18' and 18", respectively.
  • a holding bridge 19 is arranged so as to be displaceable in parallel in the arrow directions 21, which bridge 19 carries an L-shaped holding plate 20 that can be moved along the bridge moved together with the holding bridge 19 in the arrow directions 21, while a movement in the direction 22 perpendicular thereto takes place along the holding bridge 19.
  • the horizontal part of the holding plate 20 is provided with a circular hole 23 through which a tubular line 24 for the separation medium is guided so as to be axially movable.
  • a tubular line 24 for the separation medium is guided so as to be axially movable.
  • a nozzle 25 At the other end of the tubular line 24 there is a nozzle 25 (Fig. 6) through which the separation medium e.g. Water under high pressure of about 4000 bar may flow with an added abrasive.
  • the tubular line 24 is supported at the lower end thereof in the area of the nozzle 25 in a plate 40 with a bearing shell 26 in such a way that the line 24 is pressed against the bearing shell 26 and can be pivoted in this bearing shell 26. Pressing the line 24 against the bearing shell 26 can be carried out in a simple manner e.g. by means of a compression spring, not shown.
  • the line 24 can be adjusted as desired by moving the holding plate 20 on the holding bridge 19 in the X direction (arrow direction 22) and by moving in the Y direction (arrow direction 21). The free mobility of the line 24 in the hole 23 is retained.
  • the entire device described is expediently arranged on the mounting plate 27 of a CAD machine which is programmed to carry out the cutting or separating movements in accordance with a given template and in which the separating medium strikes the surface to be separated exactly perpendicularly.
  • the direction of flow of the separation medium is now adjusted by 0.2 - 0.3 °, using the device described in the arrow directions 21 and 22. With the adjustment by 0.2 - 0.3 °, a cone is defined, its generator meet the condition. It is mostly irrelevant according to the invention, wel che generators is selected and it is also possible to choose the appropriate one from the group of generators through experiments.
  • FIG. 5 A variant of the device described is shown in FIG. 5.
  • a pair of spindles is mounted in the frame 13, which consists of a spindle 28 and a spindle 29, which run perpendicular to one another in the X and Y coordinate directions and can be driven with the aid of one drive motor 30, 31 each.
  • the holding plate 20 is connected to the spindle 28 or 29 by two sides 34 and 35 which are perpendicular to one another.
  • nut-like guide pieces 36, 37 and 38, 39 are negotiated on the holding plate 20, which mesh in pairs with one of the spindles 28 and 29.
  • the plate 20 together with the spindle 29 is displaced in the X direction.
  • the plate 20 together with the spindle 28 are displaced in the Y direction.
  • the positioning of the plate 20 with the circular hole 23 can be done very precisely with the help of the motors 30 and 31, which in turn can be actuated by the CAD control.
  • the separating medium in the sense of the proposed and detailed method in such a way that an exact cut with a precisely vertical cut surface is achieved, which, however, can also be carried out conically inwards or outwards, depending on requirements.
  • Both a water jet or another liquid jet with or without an abrasive additive and a laser beam can be used as the separation medium, the separation being intended to encompass all relevant processes such as cutting, disassembling, milling, detaching or the like.
