Definitions

  • the invention relates to an apparatus and a method for bending pipes in pipe bending machines, in which the pipes to be bent are heated inductively at the bending point.
  • the tubes are often thick-walled steel tubes with wall thicknesses of 3 to 120 mm and with large diameters of 50 to 1060 mm and weights of several tons. Correspondingly large and heavy are the pipe bending machines developed for this, with which bending radii of 0.1 to 10 meters can usually be realized.
  • the tube to be bent For each bend, the tube to be bent must be clamped at its straight end in a feed carriage, while at the end to be bent a so-called flexure lock is attached.
  • a so-called flexure lock is attached.
  • annular device for inductive heating between flexure and feed carriage commonly referred to as induction ring.
  • bending locks Due to the large forces to be absorbed, bending locks are often constructed very massively and take up a lot of space. A corresponding device is used for example in the DE 10 2007 022 004 A described.
  • the bending lock is mounted on a bending arm, wherein the bending arm can be rotated about a vertical axis of rotation.
  • the object of the invention is therefore to provide an economical method available in which such assembly work can be reduced to a minimum and thus a significant increase in throughput of such bending machines can be achieved in use in multiple bends.
  • pipe movements between the individual bending operations are performed.
  • This can be a Rotation of the tube about the central axis of the tube or a longitudinal feed of the tube can be made. In this way, a variety of bending operations can be performed sequentially.
  • FIG. 1 shows an isometric view of a double bending machine
  • FIG. 2 shows a plan view
  • Fig. 3 shows a front view
  • the FIGS. 4a to 4e show the individual processes in the multiple bending of a tube in plan view.
  • FIGS. 1 to 3 show such a double bending machine 1 with the two bending arms 2 and 3 and the Biegeschlössern 4 and 5.
  • the tube not shown to be bent is pushed on the feed carriage 6 through the induction ring 7, wherein either the bending lock 4 or the bending buckle 5 detects the tube and order the axis of rotation 8 or the axis of rotation 9 bends.
  • Fig. 4 shows the process of an S-shaped bend of a tube 20th
  • Fig. 4a is the initial state.
  • the tube 20 is located in the feed carriage 6, its front tube end 21 is pushed through the induction ring 7 and is held by the bending buckle 5.
  • the bending arm 3 is therefore positioned so that the desired bending radius 12 is adjustable and the bending arm 2 is moved out of the pivoting range.
  • Fig. 4b shows the end of the first bending process, in this case a 135 degree bend.
  • Fig. 4c shows that the flexure 5 was removed and the bending arm 3 was moved away and a feed to the feed length 13 was carried out.
  • Fig. 4d shows that the bending arm 2 has been positioned so that the bending radius 14 is adjustable, and that the bending lock 4 holds the tube 20.
  • the bending arm 3 remains moved out of the swivel range.
  • Fig. 4e shows the result of the second bending operation, in this case a 135 degree bend exactly opposite the first bend.
