Definitions

  • the invention relates to a universal frame for the continuous forming of pipes, in particular in pipe welding systems, to round or profile pipes with the aid of oppositely arranged pairs, in a common plane perpendicular to the longitudinal axis of the pipe, whose appropriately trained calibers enclose the pipe.
  • a plurality of stands arranged in series, each with four rollers arranged in one plane, are used, which, according to their roller calibration, give the tube a round or profiled (rectangular or square) cross-sectional shape.
  • the universal rolling stands for forming round tubes are accordingly equipped with round-calibrated rollers, each of which is precisely tailored to the desired tube profile. This means that new rollers would have to be inserted into the stand for every other tube profile to be formed, which requires considerable conversion measures.
  • the complete universal internals can be removed from the universal rolling stands and optionally exchanged for universal internals for the production of round tubes or for the production of profile tubes.
  • the present invention makes it possible, for the first time, to use universal fittings for the production of round tubes and those for the production of profiled tubes in the same contour of a pipe welding system in the same scaffold, so that the complex conversion of the scaffolds for different pipe cross-sectional shapes is significantly reduced.
  • the downtimes of the pipe welding system are reduced so significantly that a noticeably higher output is achieved.
  • the chocks receiving the rollers of each universal installation for producing profile tubes are box-shaped and each chock is displaceably guided parallel and transversely to the axis of the roller accommodated in it on the adjacent chocks of the same universal installation.
  • the guides for moving the chocks are provided on the side cheeks of the chocks and are designed as slide strips and sliding grooves receiving these, the guides for the adjacent chocks of a universal installation being perpendicular to one another, then a dimensionally stable and precisely manageable adjustment mechanism, which, in addition to short adjustment times and the inexpensive removal and installation of the universal installation kit mentioned above, also guarantees exact shape retention of the pipes produced.
  • FIG. 1 denotes the stand of the universal rolling stand, which is suitable for the continuous forming of round tubes as well as profile tubes.
  • the universal installation identified overall by 2
  • the rollers 3 to 6 are stored in chocks.
  • the upper chock with 7, the lower chock with 8 and the chocks of the vertical rollers with 9 and 10 are designated.
  • the upper adjustment 11 and the lower adjustment 12 are provided, which accomplish the adjustment to the rolling line and / or the adjustment of the rollers relative to one another in a conventional manner.
  • the hydraulic adjustment for roller 6, which can be seen at 13 and the hydraulic adjustment 14 for roller 5, which is moved upwards in FIG. 1 on the sliding guide 15i attached to the stand 1, are provided, so that the complete universal installation is possible can be moved with the chocks 7, 8, 9 and 10 and the rollers 3, 4, 5 and 6 out of the scaffold window in the position shown in dashed lines next to the stand 1.
  • the hydraulic adjustment 14 is moved downward and acts like the adjustment 14 on the chock 9 of the vertical roller 5.
  • a universal installation for the production of profiled tubes consists of four box-shaped installation pieces which accommodate the rollers 3 to 6 and which are nested in one another in the installed state.
  • the chock receiving the upper horizontal roller 3 is designated 17, the chock receiving the lower horizontal roller 18.
  • the chocks supporting the vertical rollers are designated 19 for the roller 5 and 20 for the roller 6.
  • each chock is provided on the inner and outer flanks with guides for the adjacent chocks.
  • the chock 19 is provided on both opposite flanks with guide strips 20 and 21, the guide strip 21 corresponding to a correspondingly designed groove 23 on the inner flank of the chock 18 in the assembled state and the strip 20 in the correspondingly designed grooves 24 on the chock 17 fits for the upper horizontal roller 3.
  • the grooves 25 correspond with the strips 26 on the chock 20, the strips 27 on the chock 20 fit into the grooves 28 on the chock 17.
  • FIGS. 6 and 7 show two different shift positions of the rollers 3 to 6. As can be seen, the pipes 16 have been given 3 to 6 different cross-sectional areas by the axial displacement of the rollers.
  • the advantage of the present invention can be seen on the one hand in the interchangeability of the universal internals for round tubes and profiled tubes and on the other hand in the favorable sliding mounting of the chocks of the universal internals for the manufacture of profiled tubes, so that with the simplest structural design and therefore economical manufacturability best results on the tubes produced therewith are to be expected.
