Definitions

  • the present invention relates to a method according to the preamble of Claim 1.
  • a metal strip located on a spool is removed, if necessary, cleaned, formed into a slotted tube on a molding table in several molding stages and the Longitudinal slot of the slotted tube welded in a welding station.
  • Behind the The metal pipe is welded by a so-called Collet trigger taken with the metal band and the metal tube transported at a constant speed.
  • Collets which are mounted on two endless roller chains, the pipe. In the Collets are used for clamping jaws that exactly match the pipe diameter are adjusted.
  • the welded tube is then usually wound onto a cable spool.
  • the invention is therefore based on the object of specifying a method with which metal pipes of great length can be produced, which in one subsequent operation both in the outer diameter and in the Wall thickness can be reduced easily.
  • the main advantage of the invention is that it is simple manages the inner surface with a precisely metered amount of a lubricant to coat, which makes the subsequent drawing process easy d. H. without Damage to the inner surface of the pipe and thus without the risk of Tearing off the tube behind the die can be done.
  • the invention is based on a schematically illustrated embodiment explained in more detail.
  • a metal strip 2 is made, for example, of austenitic Steel stripped and fed a form roller set 3, in which the Metal strip 2 is gradually formed into a tube 4 with a longitudinal slot.
  • the Longitudinal slot is preferably one with a welding device 5 Laser welding device closed.
  • the welded tube 6 is behind the Welding device 5 captured by a collet trigger 7, the metal strip 2, the slotted tube 4 and the welded tube 6 through the manufacturing plant draws.
  • the collet trigger is from the German designation 11 64 355 known.
  • the welded tube 6 is then wound onto a cable drum 8.
  • the described method is limited to pipes with an outside diameter of at most 2 mm.
  • a lubricant is removed from a reservoir 10 in by means of a lance 9 the slotted tube 4 or the metal tube 6 introduced.
  • the end of the lance 9 lies particularly advantageously behind the welding device, so that the lubricant with regard to its lubricating properties by the Welding heat is not affected.
  • the lubricant can be discontinuously through the lance 9 in the still open tube 4 or the welded tube 6 can be introduced. At the subsequent The lubricant is distributed over the cable drum 8 or spool the entire inner surface of the tube 6.
  • the lubricant can be applied by spraying a thin film onto the Inner surface of the tube 6 can be applied behind the welding device 5.
  • longitudinally welded pipes can be great length d. H. up to 20,000 m or more are made from which through a subsequent drawing process tubes with a much smaller Outside diameter and a much smaller wall thickness can be produced.
