Definitions
- the invention relates to a winding tube for winding Tapes, films, sheets or the like, consisting of a helically wound metal strip consists whose adjacent tape rolls at least partially overlap, wherein the metal strip in cross-section a corrugated or has ribbed profile.
- the invention also relates a method for producing a winding tube.
- an improved winding tube known. It consists of a metal corrugated tube, made of a helically wound, longitudinally corrugated or longitudinal ribbed band is formed, with adjacent band wrap overlap at least at their edges, and indeed preferably at least half its bandwidth, so that at least two-ply sleeve wall is formed.
- the known winding tube preferably has a smooth, uninterrupted outer wall surface created by the fact that the waves or ribs a rectangular or trapezoidal Have cross section; so that the wave or rib heads on the outer and on the inner wall of the sleeve abut each other. Then the outer and inner shaft heads of the sleeve wider than the spaces between these wave heads, in the cited patent as "wave feet" be designated.
- this known winding tube is first by helically winding a longitudinally corrugated or longitudinal ribbed metal bands a tube with at its edges produced overlapping tape wounds. Then be the wave heads by exerting a radial pressure flattened the tube while broadening it.
- the pipe may be in Axial direction are compressed so that the gaps between the heads further reduce or close.
- the pipe may be in Axial direction are compressed so that the gaps between the heads further reduce or close.
- the invention is therefore based on the object, a Winding tube whose production is less expensive than the the well-known winding tube and still a smooth Exterior wall and has high strength, and a method for To create such a winding tube.
- the winding tube has a smooth outer wall and that at the same time used the material of the longitudinal ribbed or longitudinally corrugated metal strip efficiently can be exploited, so that an improved Relationship between the weight and the Peak compressive strength of the winding tube results.
- each encounter adjacent waves / ribs of the profile of the winding tube in Sections of their located on the sleeve outer wall outer Head areas to each other or almost to each other, and the on the sleeve inner wall located inner head portions of the adjacent waves / ribs are completely separate from each other spaced.
- the wave heads are flat.
- the outer wall of the resulting winding tube then not only has no Spaces between the individual outer wave heads on, but also corresponds in longitudinal section one essentially straight line.
- the so educated winding tube according to the invention is particularly suitable for Winding flat sheet material, e.g. from Aluminum sheets, which in the case of a less smooth Sleeve outer wall would deform during winding, so that at least the innermost layers of the wound material not be fully usable.
- a smooth outer wall of the winding tube is e.g. thereby get that outer shaft heads in cross section be designed trapezoidal.
- the inner wave heads on the sleeve inner wall can be designed round, So in particular keep the shape that they have Profiling the metal strip was given.
- the metal strip can advantageously so be wrapped that the tape wraps at least around the Half of their bandwidth overlap.
- the resulting pipe wall then consists of at least two tape layers, what the Strength of the winding tube further improved.
- a flat metal strip is first longitudinally corrugated or longitudinally ribbed pre-profile strip formed, its wave or rib edges with a, perpendicular to the plane of the metal strip form a flank angle ⁇ .
- the longitudinally corrugated or longitudinally ribbed tape then becomes like that helically wound, each adjacent Tape wrap at least partially overlap, leaving a Pipe is created.
- the metal strip has a cross section wavy or ribbed profile, which after the Winding on the sleeve outer wall located outside Shaft heads are wider than the one after winding up the sleeve inner wall located inner shaft heads.
- the on the outside of the tube outer heads of the waves or Ribs are then used by exerting a radial Pressure on the tube flattened and widened.
- the resulting tube is then wrapped in cores of the cut to desired length.
- the inventive method has the advantage that already with little effort a very rigid and Resistant winding tube with low total weight can be produced. Since already the initial profile like that asymmetrically designed is that the outer wave heads at the later tube outer wall are wider than the inner tube Wave heads on the later pipe inner wall, are the gaps between the outer wave heads of the output profile in Relative to these outer wave heads already relative small. For closing these gaps need the outer Wave heads therefore only to a small extent flat or to be pushed. The in the known Manufacturing process necessary, expensive subsequent Upsetting is eliminated.
- the Profile is designed for the inner wave heads relatively little material can be used, so that around more material for the webs between the outer and the inner wave heads is available. The more material used for these webs, the higher is the radial Deformation strength of the winding tube.
- the flank angle ⁇ of the pre-profile strip is preferably about 5 °, so that the Vorprofilband easily to a tube can be wound.
- the Vorprofilband first has a method Flank angle ⁇ , which is between 15 ° and 25 °. Then is the Vorprofilband stackable, that is, when winding of several band turns superimpose the flanks the band underside evenly on the flanks of the Band top. A twisting, splashing or otherwise deformation of the profile does not take place.
- the Vorprofil therefore on a Be wound on a coil of material whose diameter during Winding the specially designed pre-profile only increases comparatively slowly.
- the profiled tape can doing so by a straight or in the radial direction in the radial direction movable profile roller in the area of the casserole of the profiled strip are guided on the pre-material roll. This ensures that the band edge edges exactly put on each other and the profile band edge straight is wound.
- flank angle ⁇ of about 5 ° appropriate.
- the Vorprofilband with the flatter edge angle ⁇ is therefore, possibly rolling from the just described Starting material coil, even further deformed until the flank angle ⁇ of about 5 ° is reached.
- the pre-profile band can be at a first Production facility produced, to a Vormaterialspule wound up, transported to a second production site and there to the winding tube according to the invention be further processed.
- the latter is preferably done where the winding tubes later also for winding up Tapes, foils, etc. are needed. Then the deleted Need to transport empty cores that much Need storage space.
- FIG. 1 shows a metal strip, preferably an aluminum strip, that has been reshaped into a longitudinally corrugated pre-profile strip is.
- outer shaft heads 1 of the profile are wider than the inner shaft heads 2 of the Profile.
- the outer shaft heads 1 are later at the Outside wall of the resulting winding tube may be arranged, the inner shaft heads 2 on the inner wall.
- a wave flank forms with a vertical on the band level one Flank angle ⁇ , which lies between 15 ° and 25 °.
- the in Fig. 1 profiled strip shown is stackable or rollable, can So first stored in this form or be transported.
- the device shown in Fig. 6 For profiling this aluminum strip, for example the device shown in Fig. 6 are used.
- the Metal strip runs from a first coil 3, is in a Device 4 greases, of first profiling rollers. 5 profiled and rolled up on a primary material role 6.
- the profiled band is doing by a radial Direction straight or in the arch movable profile roller 13 in Area of the casserole of profiled tape on the Feedstock role 6 out. This ensures that the Tape edge edges are placed exactly on each other and the Profile strip is wound straight-edge.
- Fig. 2 shows the profile strip after another Forming step.
- the flank angle has an angle ⁇ decreases and is now about 5 °.
- the material is therefore not as good stackable as the Vorprofilband, However, the steeper flank angle is favorable to be in the subsequent winding process a smooth surface of the To achieve winding tube.
- the Pre-profile strip runs from the primary material roll 6 and is formed by second roll forming 7 to the Flank angle ⁇ to form.
- Figs. 3 and 4 show the metal band during the Winding process. From Fig. 3 it is clear that two layers of metal band mesh. The metal band has it nor the profile shown in Fig. 2. During the Winding process, the waves of the profile even further pushed together, so that the profile shown in Fig. 4 arises. This process step also serves in the subsequent winding process with little effort a smooth Surface of the outer wall of the winding tube to reach.
- Fig. 5 shows the final profile of a device according to the invention Winding tube as a longitudinal section through a wall of such Sleeve.
- the wide outer wave heads 1 of the profile are flattened so that a smooth, uninterrupted outer wall of the winding tube has resulted. Due to the foregoing process steps, i. by virtue of the steep flank angle ⁇ and due to the Pushing the waves together, is to flat pressing the outer shaft heads only a comparatively small radial Force necessary. The comparatively small inner Shaft heads 2 have not been further deformed. A high Flexural rigidity of the winding tube is still due to the uninterruptible outer wall and in that relative much material for the profile webs 12 between the outer and the inner shaft heads 1 and 2 has been used.
- the tape to the winding tube serves a winding device.
- the winding tubes off profiled tape can do this with two different Winding devices are produced, of which the first is shown in the left part of Fig. 7 and from a Winding mandrel 8 and profiled guide rollers 9 consists.
- Fig. 7a is an enlarged view of this winding device with winding mandrel.
- Guide rollers 9, around the Arbor 8 are arranged, cause the strip of tape helically running around the spine.
- this six guide rollers 9 provided, depending on However, pipe diameters can also be more or less Guide rollers 9 may be present.
- Winding device is a three-roll bending apparatus 10 the Tape strips the desired curvature.
- the guide rollers 9 Here, too, cause the tape strip helical running.
- a counter-roller 14 is arranged as no Winding mandrel is present.
- the guide rollers 9 are each profiled so that their Webs fill in the gaps between two wave heads. each Guide roller 9 engages over several tape turns into the profile of the pipes. Around the shaft distances of the The profile can shrink during the process Guide rollers 9 also divided into sections which cover the band slopes.
- Fig. 8 shows a guide roller 9, which in four Sections A to D is divided, with the distances between webs 15 of the guide roller 9 of section to Reduce section.
- section A the profiled Band led around the thorn, without the distances between the Reduce waves.
- sections B and C the Distances between the shafts of guide roller 9 to Guide roller 9 reduced.
- the outer Wave heads in one step or in several steps, for example, by means of section D of some Guide rollers 9, flattened.
- Fig. 9 shows a profiling and Winding device according to the prior art.
- a metal strip 3 in a device 4 greased, then pre-profiled with first profiling rollers 5, further formed with second profiling rollers 7 and finally wound up in a winding device 8, 9.
- the used device is comparatively large, and the entire manufacturing process must be in a single process be performed.
- the inventive method allows it, on the other hand, to divide the manufacturing process and thus also to reduce the size of the devices used.
