Definitions

  • the invention relates to a method and a device according to the preamble of Claims 1 and 7 (see e.g. DE-A-4 137 275).
  • DE-A-16 52 990 describes a device for continuous wave-thin-walled, in particular longitudinally welded smooth tubes are known, in which one of one Retracted spool metal strip formed into a slotted tube on his Longitudinal edges welded and fed to a corrugated device in which the welded smooth tube is provided with a helical corrugation.
  • the Corrugated device consists of a housing in which coaxial to the continuous Smooth tube a shaft head is rotatably arranged. In the well head A Weller roller ring is eccentric to the smooth tube and inclined under the screw pitch freely rotatably mounted on the surface of the Rolls smooth tube and thereby forms the wall of the smooth tube.
  • the rotary drive of the shaft head is via a gear with a trigger device coupled with which the smooth pipe is transported.
  • the well head is on a hollow shaft attached, which carries a gear on its outer surface, which with a pinion a gear transmission meshes.
  • the gear transmission is infinitely variable Gearbox coupled with a main drive motor, which at the same time the Trigger device drives.
  • corrugated device is described in DE-A-20 49 235.
  • a provided rotatably drivable well head which, as described above, via a Hollow shaft, gear transmission, continuously variable transmission and an electric motor is drivable.
  • a corrugated tool is mounted in the well head, which has a Deformation rib which produces the corrugation.
  • the deformation rib has one helical course, their clear width is smaller than the outer diameter of the smooth tube.
  • the deformation rib practically screws onto that Smooth pipe and forms a helical corrugation in the pipe wall.
  • This Welltechnik is mainly used for the production of high-frequency cables.
  • the present invention is therefore based on the object, the known Corrugation process and corrugation devices to improve that the rotating masses reduced and thereby the rotational speed of the Wellerkopfes increased and thus a higher production speed can be achieved.
  • the main advantage of the invention is the fact that by using a Hollow shaft motor the number of rotating machine elements in the shaft device a minimum can be reduced.
  • the moment of inertia of the rotating Elements is based on the moment of inertia of the hollow shaft or the rotor of the Hollow shaft motor reduced. This results in an increase in the control speed of the drive system, which leads to an improvement in the quality of the corrugated pipes.
  • the corrugated tubes for high-frequency transmission z. B. as a waveguide or used as the inner and / or outer conductor of a coaxial high-frequency cable uniform shape of the curl leads to a reduction in the height of Reflection peaks and a reduction in the reflection level.

  • From one Supply spool 7 is a metal strip 11, z. B. copper, subtracted by a Cleaning system 9 transported and fed to a molding device 13, in which the Copper tape 11 to a tube concentric with the inner conductor 5 with a longitudinal slot is formed.
  • a welding device 15 preferably a TIG Welding device, the longitudinal slot is welded.
  • a trigger device 17 Seen in the direction of flow behind the welding device 15, a trigger device 17 is arranged, which welded tube 23 and thus the inner conductor 5 and the copper strip 11 transported.
  • the trigger device 17 consists of an endless chain 19, on which in certain Distances to each other collets 21 are mounted.
  • sprockets 33 and 35 are provided around which the endless chain 19 is led around.
  • the sprocket 33 is by means of an electric motor, not shown driven and drives the chain 19 with the collets 21 mounted thereon, whereas the chain wheel 35 serves as a chain tensioning wheel.
  • a corrugated device 25 is arranged, which in the Wall of the welded tube 23 an annular or helical corrugation einformt.
  • the high-frequency cable thus produced is regulated via a dancer 27 a cable drum 29 wound up.
  • the tube forms in the finished high-frequency cable 23, after it has been corrugated, the outer conductor.
  • the trigger device 17 is the subject of DBP 11 64 355, to which reference is taken.
  • the corrugated device is shown in a fixed housing 36 .
  • the rotor 38 of the electric motor is a hollow shaft trained (hollow shaft motor).
  • the rotor 38 is fixed to a hollow shaft 39 z. B. pressed or shrunk.
  • the hollow shaft 39 is via roller bearings or bearings 40 and 41 with a longitudinally displaceable inner ring rotatable in the fixed housing 36 stored.
  • the shaft head 42 is flanged, which thus over the hollow shaft 39 is driven directly by the hollow shaft motor.

In this case it is Inner diameter of the deformation rib larger than the outer diameter of the Smooth tube 45, the washer 43 is freely rotatable and to the longitudinal axis of the smooth tube inclined and eccentric to the pipe axis. The washer 43 rolls on from the surface of the smooth tube 45 when the well head 42 rotates and generates due to the eccentric bearing, a helical corrugation (see corrugated tube 46).
  • a corrugated washer 43 used with a helical deformation rib.
  • the speed of the hollow shaft motor is coupled to the speed of the electric motor for the trigger device via a fixed ratio, depending on the dimensions of the corrugated metal tube to be produced.
  • the pitch is the distance between two wave crests.
  • the speed of the hollow shaft motor is measured by means of a resolver or incremental encoder 47.
  • This change in the specified data is determined by a sensor 48 measured.
  • the sensor 48 can either be a linear potentiometer or a pressure cell or known bending elements can be equipped with strain gauges.
  • the measured value is entered into the control loop and the speed of the hollow shaft motor either increased (when pushing) or decreased (when pulling).
