Definitions

  • the invention relates to a method for removing cold-rolled Tubes behind a cold pilger mill with batch feed and / or turning the tube, in which the tube between the rolling zone and a constant speed driver to compensate the cyclically uneven rolling speed in one Buffer zone is deflected from the rolling direction.
  • the invention further relates to a device for performing the method.
  • Another problem is that, particularly when rolling Copper tubes there is a need to increase the stroke rate of the To reduce the cold pilger mill if the one rolled at the moment Pipe the first of the holding members, namely leave the tension slide Has. If the pipe has also left the inlet chuck, is to reduce the number of strokes again. This reduction in the number of strokes works all the more clearly on the total achievable production of the Cold pilger rolling mill, the higher the number of strokes in normal operation. This is especially true if the nominal stroke rate through other measures should be increased.
  • the object of the present invention is based on the known Method and the known device an improved method and an improved device too create with which an adjustment of the reduced space requirement Buffer zone depending on the pipe diameter and pipe material variable parameters is possible.
  • the Deflection takes place in alternating directions with multiple deflections.
  • the buffering can be buffered Finished pipe lengths in the multi-curved bending line of the pipe save without the system requiring useless dimensions.
  • the deflection of the tube can be carried out using a device take place at the guide channel is closed on at least three sides and the one transverse to the guide channel in the direction of deflection of the tube has adjustable guide wall, which the deflection of the pipe.
  • FIG 1 denotes the cold pilger rolling mill, which is under Interposition of push rods 2 from the drive 3 with gear and Mass balance is driven, the rollers of the Roll the cold pilger roll stand 1 onto the pipe.
  • Each in the Dead center of the cold pilger roll stand 1 is the tube in a known manner rotated about its longitudinal axis and by a certain amount which results from the length of the caliber of the rollers.
  • Each feed means that the rollers of the cold pilger stand 1 leaving pipe accelerated by the feed path and to stop must be delayed. Especially when there are already large pipe lengths very large masses have left the cold pilger mill accelerate and slow down.
  • this buffer zone is designed so that at one S-shaped curvature of the tube in this buffer zone 4 the bending line of the S-shaped curved tube is changeable, in one such dimensions that the cyclically fluctuating change in finished tube length is recorded in the S-shaped pipe section.
  • the buffer zone is closed at least on three sides Guide channel formed into which an adjustable guide wall 6th can be integrated, which is described in more detail with reference to FIG. 2.
  • the Guide wall 6 is together with a guide roller 7 for the at R indicated tube adjustable by means of the piston-cylinder unit 8, the end position is shown in dashed lines.
  • the guide wall 6 can be different bending curves of the tube adjust, which in turn different buffer effects show different tubes.
  • the driving device 5 is suitable for the finished rolled pipe from the Pull out the cold pilger mill without the pipe end being a nuisance makes whipping movements, as is the case with the prior art can be.
  • the driver 5 enables the feed also very short pipes to downstream facilities such. B. Reel H.
  • the driver 5 can also as an additional Organ to force a smooth movement of the finished pipe be used if there are minor deviations from the set parameters are available. In any case, it is accurate Regulation of the speed (speed) of the driver 5 required, as is already the case with the prior art.
