Definitions

  • the invention relates to a universal stand for the continuous forming of tubes into round or profile tubes in tube welding systems with the help of oppositely arranged rollers in pairs in a common plane perpendicular to the tube longitudinal axis, the appropriately designed calibres enclosing the tube.
  • a universal rolling stand is known in which the chocks are removed from the stand of the stand and are optionally interchangeable with universal internals for the production of round tubes or for the production of profile tubes.
  • the invention does not relate to such a universal roll stand, but to a roll stand as is used in the contoured molded part of welding systems.
  • a plurality of scaffolds arranged one behind the other are used four rollers arranged in one plane are used, which, according to their Roll calibration, the tube a round or profiled (rectangular or give square) cross-sectional shape.
  • the universal framework for shaping round Pipes are accordingly equipped with round calibrated rolls, each of which is exact are adjusted to the desired pipe profile. That means for everyone else too forming tube profile new rollers would have to be inserted into the scaffold what requires considerable renovation work.
  • Universal scaffolds are used to manufacture profile tubes, such as square tubes known, the rollers for adjusting the tube cross-sectional shape radially and axially Carriage were slidably arranged so that by nested setting the Rolls of different cross-sectional shapes can be achieved.
  • profile tubes such as square tubes known
  • the rollers for adjusting the tube cross-sectional shape radially and axially Carriage were slidably arranged so that by nested setting the Rolls of different cross-sectional shapes can be achieved.
  • the present invention makes it possible for the first time in the contoured molded part Pipe welding system in one and the same scaffold, optionally for universal installation Manufacture of round tubes and use them for the manufacture of profile tubes, so that the complex reconstruction of the scaffolding for different pipe cross-sectional shapes is significantly reduced.
  • By exchanging the complete Universal installations reduce the downtimes of the pipe welding system essential that a noticeably higher output is achieved.
  • each Universal installation for the production of profile tubes are box-shaped and each chock parallel and transverse to the axis of the roller received in it the adjacent chocks of the same universal installation slidably guided is.
  • the guides for the adjacent chocks one Universal installation run perpendicular to each other, so it is dimensionally stable and exact feasible adjustment mechanism created, in addition to short adjustment times and Favorable removal and installation of the universal installation kit already mentioned several times, exact shape retention of the pipes produced is also guaranteed.
  • FIG 1 denotes the stand of the universal scaffold, which both for continuous forming of round tubes as well as profile tubes is suitable.
  • Stand 1 in the Stand 1 is the total of 2 designated universal installation, which from the upper horizontal roller 3, the lower horizontal roller 4 and the two Vertical rollers 5 and 6 exist.
  • 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 are designated 9 and 10.
  • the upper ones Employment 11 and the lower employment 12 are provided in a conventional manner the attitude to the rolling line and / or the attitude of the rollers to each other accomplish.
  • the hydraulic adjustment 14 is moved down and acts as the position 14 on the chock 9 of the vertical roller 5th
  • FIG 3 is a universal installation in the same stand 1 of the universal frame used for the production of profile tubes. To simplify things, they are the same here Parts labeled the same. With the positions 11, 12, 13 and 14 they are now for the cylindrical rollers 3 to 5 correspondingly designed chocks 7, 8, 9 and 10 set to the desired caliber, as will be described later. Also at this universal installation, the chocks are moved together for expansion, as described for Figure 1. In the area of the stand 1 shifted hydraulic adjustment 14, the universal installation can be completely in the Position shown in dashed lines are extended.
  • the chock receiving the upper horizontal roller 3 is designated 17, the lower horizontal roller chock with 18.
  • the vertical rollers Mounting chocks are for the roller 5 with 19 and for the roller 6 with 20 designated.
  • Adjacent chock will provide stable and compact guidance of the chocks reached each other while ensuring that an accurate axial and simultaneous parallel displacement of the rollers 3 to 6 to adjust the desired cross-sectional shapes is made possible.
  • Figures 6 and 7 there are two different displacement positions of the rollers 3 to 6 shown. Recognizable have the tubes 16 through the axial displacement of the rollers 3 to 6 different Preserve cross-sectional areas.
  • the advantage of the present invention is the interchangeability of the Universal internals for round tubes and profile tubes and on the other hand in the cheap Sliding bearing of the chocks of the universal installation for the manufacture of To see profile tubes, so that with the simplest structural design and thus economic producibility best results on the pipes manufactured with it are expected.
