Definitions

  • the invention relates to an apparatus for processing pipes or other elongated materials by means of a laser beam generated by a laser beam source having the features of the preamble of claim 1.
  • a pipe When a pipe is to be machined or cut, it is generally mounted in the chuck of a lathe, held and rotated by it, while e.g. a non-rotating cutting tool is moved laterally into the rotating tube.
  • the cutting is accomplished in several successive rotations of the tube as the insert tool gradually penetrates the rotating tube.
  • the lathe requires a heavy bed that is fixed in a permanent location.
  • stiff, but movable brackets are required for the insert tool.
  • For ease of processing such as e.g. cutting works use lasers.
  • the processing of formed tubes by laser is carried out in conventional systems by means of a fixed or linearly movable laser, under which the tube to be machined is rotated or moved. For long, already angled
  • a pipe cutting apparatus in which a central opening is centrally provided, in which the material or pipe to be cut is fixed. Around this central opening, a cutting head is guided, which is rotatable and movable in the longitudinal direction of the material to be cut. Two different drives are coordinated with each other via a processor to perform even complex cuts.
  • the cutting head is removed from the stationary laser beam source, so that the laser light has yet to be fed to the cutting head. This is also to be ensured during the rotation of the cutting head. Since the central opening is to be adapted to the diameter of the tubes, the area of use depends on the size of the central opening.
  • a preferably central opening is provided, but this is not used to set the tube, but only for receiving the tube.
  • this central opening is formed in an elongated body of revolution such as a drum, so that there is a tunnel within which the processing can take place.
  • the opening can be made so large be that both very small and very large diameters or geometries can be edited. Since the laser beam source is already arranged in the elongated body of rotation, only the energy supply and the corresponding control must be ensured in a suitable manner, which can preferably be carried out via rotary feedthroughs or slip rings in order to introduce the corresponding energies and control commands into the elongate body of revolution. Due to the flexible reception of the material to be processed, the possible geometries and rotational movements are determined by the relative movement of the rotating body and tube, so that faster machining cycles are possible by utilizing the maximum power of the laser beam.
  • FIGURE 1 shows a schematic representation of the device with a arranged in a drum laser beam source in section.
  • FIG. 1 schematically shows an apparatus for processing pipes or other elongate materials 6, wherein these pipes and materials can have different cross-sections and different diameters and geometries.
  • the machining takes place by means of a laser beam 8 generated by a laser source 7, wherein all machining processes are possible, which can be effected with laser beam sources.
  • laser processes are provided for cutting, separating, marking, cleaning, joining, abrading, hardening or labeling of materials or, for example, for stripping wires.
  • the laser beam 8 can arrive in any manner from the laser beam source 7 to the processing point on the material to be processed 6.
  • a free laser beam 8 and a beam guiding and / or beam-shaping element 9 in the form of a deflecting element are shown.
  • the beam could just as well be guided eg by a fiber or a hollow waveguide or the like.
  • beam guiding and / or beam-shaping element 9 thereby includes all elements guiding the laser beam, such as fibers, mirrors, toroids, deflectors, beam splitters, scanners, etc. and / or elements forming the laser beam, such as lenses or combined elements such as focusing mirrors, adaptive mirrors, etc. understood.
  • a relative to the machine bed slidably and rotatably mounted support member for holding a tool or cutting means is provided on a machine bed 1.
  • This holding element is formed by an elongated body of revolution, which is formed in the embodiment as a drum 3.
  • the longitudinal rotational body can have any external geometry and / or internal geometry in which a tunnel is formed in the longitudinal direction for receiving the material to be processed.
  • the holding element or the elongated body of revolution is referred to as drum 3.
  • the holding element or the drum 3 surrounds a central, insofar tunnel-like opening 5, which is penetrated during processing of the material to be processed 6. In principle, a decentralized opening is also conceivable, provided that the desired processing is ensured.
  • the material 6 in the central opening 5 is not fixed, but is freely received therein. It goes without saying that the material or the pipe to be held elsewhere, such as on a bearing or on a robot arm, at least so that it can be moved if necessary in the longitudinal direction or rotated about its central axis mm. In this case, pipes or materials can be edited that are already connected to other elements or are already bent. In addition, the material can be supplied both in cut pieces and endless the device.
  • the laser beam source 7 is arranged inside.
  • suitable material 6 of any cross-section can optionally be cut to length or fed endlessly.
  • the material 6 can rotate about the central axis mm or rigidly guided and it can also be moved in the longitudinal direction or fixed to the machine bed 1.
  • a laser beam source 7 is arranged so that by rotation of the drum 3, a material processing takes place on the circumference of the workpiece.
  • the beam is deflected by a suitable beam guiding and / or beam-shaping element 9 to the workpiece at a suitable angle.
  • the laser beam source 7 thus emits the beam substantially parallel to the central axis mm, so that the beam guiding and / or beam-shaping element 9 deflects the laser beam onto the material 6 to be cut in the drum 3.
  • any other arrangement of the laser beam source 7 is conceivable as long as the laser beam source 7 is disposed within the drum 3.
  • the laser beam source can also be aligned radially in the direction of the processing point without the need for a beam guiding and / or beam-shaping element 9.
  • the beam guiding and / or beam-shaping element 9 and / or the laser beam source can also be radially and / or axially adjustable with respect to the drum by means of a drive, not shown in the drawing, around the focal point of the laser beam to different and / or non-rotationally symmetric or asymmetrical Set geometries.
  • Another bearing block 11 which is movable in the longitudinal direction of the material 6 to be processed, supports the material handling.
  • the relative movement between the material 6 and the drum 3 is determined by the advance of the material 6 and the movement of the bearing block 2.
  • the relative velocity of the tool or laser beam source 7 to the material on the circumference is determined by the rotational speed of drum 3 and material 6.
  • the tunnel formed by the central opening 5 in the drum 3 allows a variety of processing of the material to be machined 6. On the one hand, any small or large diameter can be used as long as the central opening 5 in diameter is large enough. On the other hand, no optics for the laser beam interfere with the machining within the central aperture.
  • the drum 3 also has the advantage that relatively long cuts or processes can take place in the longitudinal direction of the material, it also being possible, if necessary, for the drum to be lengthened accordingly.
