Definitions
- the invention relates to a method for producing a connecting element or node element, in particular for steel structures of towers, preferably for wind turbines, as well as a connection or node element.
- masts and towers in particular on wind turbines or tension masts are regularly struts at different heights and angles in the
- Object of the present invention is to provide components, in particular connection or node elements, which avoid the disadvantages listed above.
- the above-indicated object is achieved by a method for producing a connecting element, in particular for steel structures of Towers, preferably for wind turbines having the features of claim 1.
- a blank a blank, a pipe section or a forging blank is preferably used.
- spinning rollers is understood to mean a production method of the forming technique which is used for producing mostly rotationally symmetrical hollow bodies.
- the so-called Ronde tensioned in front of the end face of a spinning chuck.
- the spinning chuck represents the tool that shapes the geometry of the component as an inner mold.
- the chuck is then set in rotation together with the blank by the main spindle drive of the spinning machine.
- the actual forming of the blank to the component takes place in several stages by a spinning tool, which is moved, for example, step by step from the center of the blank to the edge and back again. As this movement progresses in the axial direction, the blank gradually approaches the geometry of the chuck.
- a spinning roller is often used as a tool and the movement is computer-controlled.
- connection or node elements are provided which can be easily connected to adjacent components, have a force flow which is improved compared to the prior art and can be produced inexpensively.
- connection of the connecting element in the desired position and position can be made possible by the opposite end of the flange is respectively adapted.
- different sizes and lengths are possible at Corresponding trimming also allow a strong angled positioning.
- a further advantage of the invention is that the connecting elements produced according to the invention have no weld seam, such as components produced by bending, so that the notch effect is reduced.
- the advantages of the present invention are accordingly the reduction of the number of parts, the missing weld in the flange area and the improved power flow.
- the material thickness of the flange by means of stretching or pushing during the flow-forming operation in relation to the material thickness of the blank.
- the transition between the flange and the jacket is formed with a flowing wall thickness. Due to the individual adjustability of the wall thickness in the various regions of the connecting element, particular advantages are achieved.
- Compressive residual stresses can be set, thus significantly improving the fatigue strength.
- the flange is formed on the inside.
- a blank As the blank.
- the material thickness on the flange can be adjusted by stretching or pushing material from adjacent regions, in particular from regions which are allocated in the later trimming. As a result, the stability of the inner flange is increased and at the same time reduces the amount of waste.
- the flange can be formed on the outside. In this case, it is preferable to use as a blank a pipe section or a forging blank. A tapered transition region is then formed internally as a jacket, which is welded to one end of a mast construction, in particular a corner handle.
- the sheath may be conical, with the flange formed at the tapered end of the sheath.
- a particularly stable construction is achieved by connecting the flared end of the shell with a larger cross section to the mast construction, while the cross section of the flange is adapted to the strut to be attached.
- the flange of the opposite end of the shell is adjusted by trimming to the outer contour of the component, including in particular a laser or water jet cutting or a plasma or flame cutting is applied.
- the open end of the preferably conical jacket can be welded after the trimming to the outer contour of the mast construction, in particular the corner post.
- the flange of the opposite end of the shell with a further flange.
- the connecting element on both sides of the shell on a flange, wherein the first flange for connection to a strut and the further flange is provided for connection to a mast construction or with a corner post.
- the further flange is formed by spin forming, whereby the advantages described above are also achieved at this end of the shell.
- connection or node element the described method can also be used to produce flange connections for any pipes.
- This application gives the same advantages in terms of material thickness and stress properties.
- external flanges here also the use of a pipe section or forging blank, instead of a blank for the flow-forming process for a
- Connecting element in particular for steel structures of towers,
- a flange and with a jacket wherein the jacket is integrally connected to the flange and wherein the flange of the opposite end of the shell is adapted to the contour of the component with which the jacket is to be connected.
- Fig. 1 shows a first embodiment of an inventive
- Fig. 2 shows the embodiment shown in Fig. 1 in cross section along the
- FIGS. 1 and 2 the embodiment shown in FIGS. 1 and 2 in a

- FIG. 6 is a schematic representation for explaining the inventive
- FIGS. 1 to 4 show a first exemplary embodiment of a connecting element or node element 10 according to the invention.
- connection or node element 10 hereinafter only
- Called connecting element is particularly suitable for steel structures of towers, preferably for wind turbines and in particular with a
- the connecting element 10 has a flange 12 and a jacket 14, wherein the jacket 14 integrally connects to the flange 12 and
- flange 12 opposite end of the jacket 14 is adapted to the contour of the component of a steel structure, in particular a tubular Eckstiels 30 with a round or polygonal cross-section with which the jacket 1 is to be connected.
- the jacket 14 has a conical shape which also has a section 16 which is also conical but at a shallower angle.
- the flange 12 is connected to the tapered end of the conical jacket 14.
- a cylindrical portion 18 is provided, which connects the flange 12 with the jacket 14 and 16.
- the flange 12 is formed lying inside and forms an opening 20. With the flange 12 can in a conventional manner Strive to be connected to a steel structure.
- the connecting element 10 can be welded to the corner post 30.
- the axis of the connecting element 10 is aligned substantially perpendicular to the axis of the corner post 30.
- Fig. 5 now shows a further embodiment of an inventive
- the jacket 14 has a cylindrical portion 22 which is oblique to the axis of
- Connecting element 10 is separated.
- the connecting member 10 can be connected at an angle with the corner post 30.
- Fig. 6 shows a schematic representation of the basic sequence of a method according to the invention for producing a connection or
- junction element 10 in particular for steel structures of towers, preferably for wind turbines, in which from a blank 40 by means of a
- the flange 12 opposite end of the jacket 14 is adapted to the contour of the component, such as a corner handle 30, with which the jacket 14 is to be connected. This last step is not shown in the drawing.
- a blank 40 made of steel is used as the blank
- the blank 40 is clamped between a spindle 50 of a flow-forming machine and a spindle 52 which shapes the geometry of the connecting element 10 as an inner mold.
- the pressing tools 54 and 56 shown schematically the blank 40 is reshaped so that after completion of the spin forming the desired shape of the connecting element 10 is achieved.
- Fig. 6 also shows the forming step, with which the material thickness of the flange 12 by sliding during the flow-forming against the
- Material thickness of the blank 40 is increased.
- the starting material of the blank 40 is thinner than the later formed flange 12.
- material is shifted from the laterally arranged trim 58 and thus produces a greater thickness of the flange 12. This has the particular advantage that less trimming 58 is obtained from the middle and the ironed outer jacket 14 is thinner
