Definitions

  • the invention relates to a method for producing pipes from metallic Material in a planetary cross-rolling mill, in which a tube blank is the planetary cross-rolling mill fed and between a number of rollers and one mandrel-shaped inner tool is rolled into the tube.
  • the invention further relates to a planetary cross roll mill for the production of pipes from metallic Material.
  • a planetary cross-rolling mill known. Such a method and a planetary cross roll mill is described for example in DE 101 07 567 A1.
  • the planetary cross-rolling mill fed a pipe blank, which rolled in a gap to the pipe that is between a number of planetary diagonal rollers and one forms thorn-shaped inner tool.
  • the invention is therefore based on the object of a method of the type mentioned Art as well as to create a planetary diagonal rolling mill that the above Overcomes disadvantages. This is intended to increase output rates as well the reliability of planetary diagonal rolling are guaranteed.
  • this object is achieved by the invention in that that the inner tool at the time the beginning of a Tube blank and / or the end of a tube blank in the area of the rollers occurs, against the conveying direction of the tube blank from its working position by one predetermined displacement is withdrawn and after the beginning the tube blank and / or the end of the tube blank passes the area of the rollers has been pushed back into his working position.
  • the beginning of the tube blank and / or the end of the tube blank is preferred with the inner tool withdrawn, rolled together in a liquid-tight manner by the rollers. It also increases the economics of the process if at least Two pipe blanks are fed to the planetary cross-rolling mill become. Furthermore, it can be provided that the planetary cross roll mill is continuously fed with pipe blanks.
  • Another training provides that by measuring the rotation of the rolled Pipe around its longitudinal axis and controlled or regulated activation of the Drive or drives the rollers a rotation of the tube around its Longitudinal axis is balanced. It can be controlled or regulated to the Main drive of the rollers can be influenced; alternatively or additively be provided that controlled or regulated on a superposition drive the rollers are acted on.
  • the tube blank and / or the Tube advantageously subjected to cooling with liquid cooling medium.
  • the planetary cross-rolling mill according to the invention for the production of pipes metallic material has a number of rollers and an internal tool, so that a pipe blank in the gap between the rollers and the inner tool for Pipe can be rolled.
  • the planetary cross roll mill is according to the invention characterized by means for timed or regulated withdrawal the inner tool from its working position by a predetermined displacement against the direction of conveyance of the tube blank as well as the time-controlled or controlled return of the inner tool to its working position.
  • the means as hydraulic or electrical Linear actuator are formed.
  • Fig. 1 is shown schematically, as in a planetary cross-rolling mill 2, the not shown in detail, but is constructed in a known manner, a pipe blank 3 is rolled into a tube 1.
  • the tube blank 3 enters in the conveying direction R in the planetary cross-rolling mill 2 and is rolled into tube 1.
  • a number of rollers 4 evenly distributed in the circumferential direction arranged around the tube 1, only one roller 4 being outlined in FIG. 1.
  • a mandrel-shaped inner tool 5 is positioned between the rollers 4, that there is a roll gap that the material of the tube blank 3 to Rolls tube 1 with the desired diameter.
  • means 10 are provided. These can be hydraulic or operated electrically.
  • Especially the planetary diagonal rolling mill 2 is preferably operated continuously with tube blanks 3 loaded.
  • the advantage of the method described is that even during the Rolling the slug joint 12 (see FIG. 2) continues to roll 4 with the required Rolling emulsion is applied and the emerging pipe 1 are cooled can, without rolling emulsion or cooling water into the interior of the tube 1 arrives. By protecting the inside of the pipe, it is easy to process further of the tube 1 allows. At the same time, the rollers 4 are well lubricated and cooled the outlet pipe 1. Thanks to constant cooling down to the end of the pipe does not find any oxidation due to excessive copper and copper alloys Rolled material temperature at the outlet from the planetary diagonal rolling mill 2 instead of what a reduced proportion of scrap results.
