Definitions

  • the invention relates to a device for straightening a tube having a radially expandable expander head immersed in the tube and at least one straightening saddle which can be positioned at a desired position along the longitudinal axis of the tube and radial to a part of the wall of the tube Force to direct the pipe.
  • Document JP-A 61 099 522 shows a device according to the preamble of claim 1.
  • the invention is therefore based on the object, a pipe straightening device of the type mentioned in such a way that the mentioned disadvantages are overcome and thus the manufacturing process of the pipe and in particular the straightening process is improved.
  • the at least one saddle saddle is formed in simultaneous cooperation with the expander head as Rohrjustiervorraum, wherein an insertable into the tube interior rod or tubular trained spar is provided, which is arranged at least one saddle adjustable along the longitudinal axis of the spar and means are provided for urging the saddle from the longitudinal axis of the support member radially outward so that the saddle presses against the inner surface of the tube.
  • a first development provides means of movement with which the at least one saddle can be positioned at a predetermined position along the longitudinal axis of the spar.
  • the expander head is arranged at an axial end of the spar, which has radially expandable segments relative to the longitudinal axis of the spar.
  • each saddle is in contact with a wedge, is moved radially by the translational movement in the direction of the longitudinal axis of the spar of the saddle.
  • a linear actuator is used for the movement of the wedge.
  • Another embodiment provides measuring means with which the radial distance of the saddle from the longitudinal axis of the spar can be measured.
  • At least one measuring means can be arranged on the spar, with which the distance between the longitudinal axis of the spar and the inner surface of the tube can be measured.
  • a plurality of measuring means are arranged evenly distributed over the circumference of the spar.
  • the at least one saddle is arranged together with means for radially moving the saddle on a support which is translationally movable relative to the spar in the direction of its longitudinal axis.
  • the device according to the invention for straightening a tube advantageously ensures a relatively short force flow between the expander head and the straightening calipers, as a result of which the force to be introduced can be applied in a more accurately metered manner.
  • the efficiency of the device and thus the tube manufacturing process is thereby improved.
  • the pre-positioning can be provided by means of Rohrjustiervorraum at any point.
  • the invention allows quasi "remote-controlled" saddle saddles, which are arranged displaceably on a support element, for pre-positioning, being used as a carrier element in particular the spar of the expander for expanding the tube used.
  • the tube can be bent from the inside and thus directed with a very short power flow.
  • the size and direction of the straightening moment can easily be adjusted individually for each expansion step of the tube, so that the straightening process can be carried out in an optimized manner.
  • the straightening process can be partially automated. But even if no automation is provided, the straightening process can be manually corrected at least interactively.
  • the proposed device is used in particular when straightening large pipes.
  • a larger, thick-walled tube 2 has a distortion after welding, ie it is not ideal straight.
  • the device 1 is used for straightening the tube 2.
  • the device 1 has a spar 4.
  • the longitudinal axis L T of the spar 4 is identical to the longitudinal axis L of the tube 2.
  • the device 1 is arranged for straightening the tube 2 in the interior I of the tube 2.
  • an expander head 8 is arranged, which has a plurality of segments 9 distributed over the circumference.
  • the expander head 8 has a truncated pyramid 15 on which the segments 9 are arranged to be radially displaceable.
  • the spar 4 still comprises a pull rod 17, these parts being arranged coaxially with each other. The spar 4 interacts axially immovably with the segments 9.
  • a carrier 14 in the form of a carrier plate or the like is arranged on the spar 4.
  • the carrier 14 can be positioned with moving means 6 at a desired position x of the spar 4.
  • wedges 10 are arranged, which can be moved in the direction of the longitudinal axis L T of the spar 4 on the support 14 by means of linear actuators 11.
  • the wedges 10 act together with a plurality of a leveling device forming straightening saddles 3, which are arranged on the wedges 10 so that when moving the wedges 10 in the direction of the longitudinal axis L T the straightening saddles 3 are moved radially outward.
  • the straightening saddles 3 generate a radially outwardly directed force F on the inner surface of the tube 2.
  • the current displacement of the wedges 10 relative to the spar 4 can be detected by measuring means 12.
  • the value measured by the measuring means 12 can be used to determine the radial distance of the radially outer surface of the saddle member 3 from the longitudinal axis L T of the bar 4 via the conical surface of the wedge 10.
  • the spar 4 or support 14 and the wedges 10 and straightening saddles 3 arranged on it together with the linear actuators 11 and the measuring means 12 represent means 5 with which the straightening saddles 3 can be pressed radially outward from the longitudinal axis L T of the spar 4 , so that the straightening saddles 3 produce the desired Vorposition réelles free by applying the forces F, ie by pressing against the pipe inner wall.
  • measuring means 13 On the bar 4 measuring means 13 may further be arranged, which is the distance of the inner surface of the tube 2 from the bar 4 determine. Of these measuring means 13 may be arranged evenly distributed over the circumference several.
  • Fig. 1 it is shown that the measuring means 13 is fixedly arranged on the spar 4 and measures the distance to the inner tube wall. It should be noted that the measuring means 13 can also be arranged on the support plate 14 and thus then moves along with the displacement of the support plate 14 relative to the spar 4.
  • the straightening process control means (not shown) which detect the position of the inner wall of the tube 2 by the measuring means 13, namely at different axial positions of the tube 2. Furthermore, the measuring means 12 provide information This can be determined by algorithms known per se, at which axial position x of the tube 2 on which saddle saddle 3, a pressing force F must be applied in order to interact with the expander head. 8 be able to initiate such a bending moment in the tube 2 that the highest possible straightness of the tube is achieved.
  • the saddle saddle 3 can be designed as plates or to compensate for longitudinal expansion of the tube 2 as a plate roller segment or as a sliding plate.
  • Both the movement means 6 and the linear actuators 11 are schematically sketched in the embodiment as piston-cylinder units. It should also be noted that any movement means can be used, for example electric drives with spindle systems.
  • the four straightening saddles 3 are arranged uniformly distributed over the circumference of the spar 4.
  • at least one saddle 3 is required. The more straightening saddles 3 the tube adjusting device has on the spar 4, the more accurate straightening can be done.
