Definitions
- the invention relates to a device for straightening a pipe, the one in the Pipe dipping, radially expandable expander head and at least one Direction saddle, which at a desired position along the longitudinal axis the pipe can be positioned and placed on a part of the wall of the pipe Pipe can exert a radial force to direct the pipe.
- the invention is therefore based on the object, a pipe straightening the initially developed type such that the disadvantages mentioned be overcome and thus the manufacturing process of the pipe and in particular the straightening process is improved.
- the at least one Directional saddle in simultaneous cooperation with the expander head as Rohrjustiervorraum is formed, wherein an insertable into the tube interior rods or tubular trained Holm is provided, the at least one saddle slidably disposed along the longitudinal axis of the spar and wherein Means are provided, with which the saddle of the longitudinal axis of the support element can be pressed radially outward, so that the saddle on the inner surface of the tube presses.
- a first development provides means of movement with which the at least a saddle at a predetermined position along the longitudinal axis of the Holmes can be positioned.
- the expander head is arranged at an axial end of the spar, having radially expandable relative to the longitudinal axis of the spar segments.
- each saddle is associated with a wedge, by its translational Movement in the direction of the longitudinal axis of the spar of the saddle saddle moves radially becomes.
- a linear actuator is used for the movement of the wedge Commitment.
- 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 spar Tube can be measured. Preference is given to several measuring means evenly distributed over the circumference of the spar.
- the at least one saddle velvet Means for radially moving the saddle is disposed on a support, the translational relative to the spar in the direction of its longitudinal axis is movable.
- the inventive device for straightening a tube is in an advantageous Make a relatively short power flow between the expander head and the straightening calipers sure, whereby the force to be introduced are applied more precisely can. The efficiency of the device and thus the tube manufacturing process is thereby improved. Furthermore, the pre-positioning by means of Rohrjustiervorraum be provided at any point.
- the invention allows quasi "remote-controlled" saddle saddles on a support element are arranged displaceably, for pre-positioning, wherein as a carrier element
- the spar of the expander to expand the tube to Use comes. This allows the tube with very short power flow from the inside be bent and thus be addressed.
- the size and direction of the straightening moment is easy for every expansion step of the tube individually adjustable, so that the straightening process is optimized can be carried out.
- the straightening process can be partially automate. But even if no automation provided If necessary, the straightening process can be corrected manually, at least interactively.
- the proposed device comes in particular when straightening large pipes for use.
- 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 thereby with moving means 6 at a desired Position x of the spar 4 are positioned.
- 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 respective linear actuators 11 By appropriate control of the respective linear actuators 11 is exactly that point coincides with the action of the expander head 8 a force F produced for pre-positioning, the expander head 8 such deformation (Bend) of the tube 2 allows its straightness to be achieved.
- 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.
- On the beam 4 measuring means 13 can be further arranged, which determine the distance of the inner surface of the tube 2 from the spar 4. Of these measuring means 13 may be arranged evenly distributed over the circumference several.
- Fig. 1 it is shown that the measuring means 13 fixedly arranged on the spar 4 is and measures the distance to the inner tube wall. It should be noted that the Measuring means 13 as well as on the support plate 14 may be arranged and so that it then moves along with the displacement of the support plate 14 relative to the spar 4.
- the position of the inner wall of the tube 2 by the measuring means 13 detect, at different axial positions of the tube 2. Furthermore, the measuring means 12 provide information about the radial position of the radially outer ends of the saddles 3. In this way can be determined by algorithms known per se, on which axial position x of the tube 2 on which saddle saddle 3 a pressing force F must be applied to in conjunction with the expander head 8 a be able to initiate such bending moment in the tube 2 that the highest possible Straightness of the tube is achieved.
- the saddles 3 can be used as plates or to compensate for longitudinal strains of the tube 2 also formed as a plate-roller segment or as a sliding plate be.
- Both the moving means 6 and the linear actuators 11 are in the embodiment sketched schematically as piston-cylinder units. Also to this is noted that any movement means can be used, for example Electric drives with spindle systems.
- the four straightening saddles 3 are uniform over the circumference des Holmes 4 arranged distributed.
- the tube 2 is at least one Saddle 3 required. The more straightening saddles 3 the Rohrjustiervorraum on the Holm 4 has, the more accurate judging can be done.
