Definitions
- the invention relates to a system for the continuous shaping of longitudinally slotted tubes made of a flat material with roll stands arranged one behind the other in the system direction, each of which carries at least one roller, and a method for the continuous shaping of longitudinally slotted tubes made of a flat material, the flat material being successively guided past a plurality of roller arrangements and bent accordingly becomes.
- a system for the continuous shaping of longitudinally slotted tubes from a flat material with mill stands arranged one behind the other and each carrying at least one roll, the system being characterized in that at least one of the roll stands has a roll carrier which carries at least three rollers arranged one behind the other in the system direction and is freely supported on the roll stand carrying the roller carrier via roller adjustment means with a degree of freedom of rotation parallel to at least one roller axis of a roller carried by the roller carrier and / or perpendicular to the material running direction.
- This makes it possible to distribute the local contact pressure of the rollers carried by the roller carrier or the rollers successively acting on the flat material as evenly as possible over the flat material and in particular to significantly reduce instabilities.
- the roll carrier is freely mounted on the roll stand with regard to the aforementioned degree of freedom of rotation. Accordingly, it is advantageous if the three rollers which successively act on the flat material can freely position themselves relative to one another. In this way, the rolling force can be distributed as evenly as possible over the two rollers, so that the force applied by one of the two rollers to the flat material can be minimized, which accordingly minimizes the risk of markings.
- Free positioning or free storage can take place, for example, by a rocker-like mounting of the roller carrier or by means of hydraulic mounting in the form of a hydraulic balance.
- rolling stand is understood to mean arrangements which absorb the rolling forces and counteract them in such a way that the roller positions are held to a predetermined extent during the rolling become.
- the rolling forces can be introduced into the building surrounding the plant on the one hand, or preferably neutralized via appropriately ring-shaped or otherwise closed rolling stands.
- the possibility of free adjustment of the roller carriers means that the axes of the two rollers are rigidly connected to one another, but that force differences can be compensated for by the free adjustability, so that the rolling forces of these two rollers are averaged and thus introduced into the roller stand without torque become.
- a method for continuously forming longitudinally slotted tubes from a flat material is also proposed, the flat material being successively guided past a plurality of roller arrangements and being bent accordingly, and the method being distinguished, inter alia, by the fact that the rolling forces are averaged by at least three rollers acting successively on the flat material are introduced into the roll stand and / or three successively acting rolls are carried by a common roll carrier, which stands freely.
- the two rollers acting successively on the flat material are jointed together, so that they behave essentially like a roller.
- system direction denotes the average direction of flow of the material through the system.
- the plant direction is perpendicular to the transverse direction, which is essentially defined by cross-sections of the flat material running through the plant at the same time.
- the term "one behind the other in the system direction” denotes an arrangement which is successively passed through by a cross section of the flat material.
- such a system also has a material running direction, which is locally defined by the movement of a point of the flat material. Apart from natural oscillations or uneven running that occur with such rolling processes, the material direction remains constant at one point in the system when the system has run in.
- the three rollers carried by the roller carrier are preferably arranged one behind the other in the material running direction, so that at least one material point of the flat material which touches a first of the two rollers arranged one behind the other in the machine direction also touches the second of the two rollers arranged one behind the other in the machine direction.
- this contact does not necessarily have to take place at the same axial height of the two rollers, so that the carrier can easily be crooked in relation to the material running direction. In this way, the rolling force that is applied via the common roller carrier can be distributed even further in the flat material.
- a roll carrier should not carry more than ten rolls arranged one behind the other in the system direction, or that the rolling forces of no more than ten rolls acting successively on the flat material are averaged into the roll stand and / or no more than ten successively acting Rollers should line up freely, otherwise the advantages of free roll adjustment or the corresponding averaging will no longer be felt.
- roller carrier is arranged on the roller stand carrying the roller carrier by means of roller adjustment means with a degree of freedom of rotation perpendicular to a roller axis of a roller carried by it and / or parallel to the material direction of the roller belonging to this roller axis.
- roller adjustment means with a degree of freedom of rotation perpendicular to a roller axis of a roller carried by it and / or parallel to the material direction of the roller belonging to this roller axis.
- roller carrier is perpendicular to a roller axis of a roller carried by the roller carrier and / or parallel to the direction of material movement in relation to a degree of freedom of rotation this roll axis are freely supported on the roll stand carrying the roll support.
- the roller carrier can position itself in such a way that forces acting on the rollers in cross-section are minimized, which ultimately also results in a minimization of the local forces and consequently a corresponding reduction in markings.
- this embodiment can also be used, regardless of the use of a roller carrier, to ensure that a roller independently positions itself as gently as possible with respect to the cross section of the flat material.
- a system for the continuous shaping of longitudinally slotted tubes from a flat material with rolling stands arranged one behind the other in the system direction, each of which carries at least one roller is advantageous, in which at least one of the rollers via roller adjustment means with a degree of freedom of rotation perpendicular to a roller axis and / or parallel to the material running direction of the belonging to this roller axis or parallel to the material running direction of a roller carried by the roller carrier is freely supported on the roll stand carrying the roller.
- a method for the continuous shaping of longitudinally slotted tubes from a flat material is advantageous as a solution, the flat material being successively guided past several roller arrangements and being bent accordingly, and the method being characterized in that at least one roller is perpendicular to its roller axis and / or parallel to the material running direction this roller freely follows the respective rolling forces.
- the free adjustability with a suitable design of the overall system also has the advantage that the system is relatively easy to set up or adjust, since the free adjustability means that there are angular deviations due to the relatively complex deformations of the workpiece for the continuous shaping of longitudinally slotted tubes between the workpiece and Rolling when changing the setting or setting itself is almost unavoidable with rigid guidance, due to the free adjustability within corresponding limits compensate automatically.
- This advantage already follows in the case of free adjustability only in one dimension, a combination of the free adjustability perpendicular and parallel to the roller axis or perpendicular and parallel to the material running direction, as described above, being correspondingly cumulatively advantageous.
- the above-mentioned degrees of freedom of rotation can be provided by suitable guides or by rotating or ball joints of the system. It is usually easier to implement in terms of mechanical engineering if the two degrees of freedom of rotation mentioned above are each represented in a separate guide device or in a separate swivel joint. This is done in a structurally particularly simple manner by means of swivel joints with annular bearing surfaces, which can be realized, for example, by means of a joint pin which is inserted into a fork and which carries a joint head of the movable assembly.
- the structural simplicity however, has the disadvantage - depending on the specific circumstances - that the axis of rotation can also be found coaxially with the hinge pin.
- Suitable guides offer greater freedom, such as linear guides with curved running surfaces.
- Such arrangements make it possible to realize much more complex movements of the respective assemblies relative to one another, so that in particular the axis of rotation can also be chosen more freely and - in the case of more complex movements - can also be selected to be displaceable depending on the position of the assemblies which are movable relative to one another.
- the overall arrangement can be in an unstable equilibrium position with respect to the swivel joint or the guide, so that, particularly with high rolling forces, there is a risk that the arrangement at the height of the guide or at the height of the swivel joint breaks out, which can be triggered, for example, by process-inherent vibrations or the like.
- the rolls can be chosen to be wider than their half diameter, in particular even wider than their diameter.
- the roller adjustment means can have, at least in an adjustment position, an axis of rotation which is shown in an adjustment position of the roller adjustment means with respect to the degrees of freedom of rotation from the perspective of the corresponding roller beyond the flat material.
- the roller stabilizes itself, so that unrest in the process can ultimately be countered by the roller in a stable manner.
- the roll perpendicular to its roll axis and parallel to the material running direction of this roll, follows the respective rolling forces at least in a set-up position with a rotation axis shown from the view of the corresponding roll beyond the flat material.
- the two rollers are preferably guided in at least one setting position with an axis of rotation shown beyond the flat material from the perspective of the two successively acting rollers in order to realize the advantages explained above.
- a rotation axis does not necessarily have to be provided in all of the positions of adjustment and not necessarily with respect to both of the above-mentioned degrees of freedom of rotation. This depends in particular on the other process parameters, such as the rolling forces, the geometries of the rolls and the expected uneven running.
- a spring arrangement or a corresponding suspension of the roller adjusting means can be provided in the direction of movement, so that the rollers or roller carriers always strive for a zero position.
- mechanical suspensions of any kind can be used for this.
- hydraulic or pneumatic spring devices are also conceivable accordingly. In this way, in particular when changing the flat material, it can be ensured in a relatively simple manner that new flat material can easily run into the system.
- a plurality of roll stands 45 (here only exemplarily numbered and shown schematically by a fixed cylinder, which is not separately numbered) are arranged one behind the other in a line direction 31, so that each cross section of the flat material 15 successively past each of the roll stands 45.
- the roll stands 45 each carry rolls 40 on roll supports 48, wherein for reasons of clarity in the Figures 1 to 3 only a part of the rolls, which are each necessary for molding, is shown.
- roller carriers 48 and roll stands 45 on the right-hand side of the installation has been omitted for the sake of clarity, since these are generally designed in mirror image to the rollers 40, roller carriers 48 and rolling stands 45 on the left-hand side of the installation.
- the arrangement of the rollers 40 is in any case adapted in a suitable manner to the material requirements and desired bending radii in each specific embodiment.
- the tube 10 can subsequently be fed to a finishing operation, in particular, for example, to a weld of the slot which has remained open.
- the plant direction 31 ultimately represents approximately an average value of the direction of flow of the flat material 15 through the plant, with a cross section of the flat material ultimately running successively past the roll stands 45 or the rolls 40 due to the process.
- the individual material points of such a cross section have different material orientations 32 corresponding to the bending process, whereby it can be assumed that, apart from process-related fluctuations, each material point of the flat material 15 arranged identically in cross section will also have the same material orientation 32 at the same system height.
- the rollers 40 come into contact with the flat material 15, a material running direction 32 of the respective roller 40 or on the respective roller 40 follows immediately.
- a corresponding material running direction 32 is also shown in FIGS Figures 4, 6, 7 and 10th indicated schematically.
- the roller arrangements include Figures 4 to 11 four rollers 40 each, which are mounted on a common roller carrier 48. In this way, the rolling forces acting on the roller carrier 48 are distributed among the four on them provided rolls 40 and are thus introduced into the flat material 15 over a relatively large area.
- rollers 40 are each connected via a fork 52 of the roller adjustment means 50 to the roll stand 45, which in turn has a cylinder (not numbered) in which the fork 52 with a piston (not shown) is inserted.
- the fork 52 of each individual roller carrier 48 can be set parallel to the orientation of the cylinder or the piston in the direction of the center of the system, which requires a very precise adjustment of the roller carrier 48 and therefore of the rollers 40.
- the fork 52 carries an intermediate carrier 54, this according to the embodiment Figures 4 to 7 is implemented by a pivot pin 57, while this after the arrangement Figures 8 to 11 by means of rotary guide surfaces 58, which are formed on the one hand on the fork 52 and on the other hand on the intermediate carrier 54, and via a securing link 59 (see Figure 8 ) happens, which runs in a not separately numbered securing groove, so that the intermediate carrier 54 is secured to the fork 52.
- the pivot pin 57 requires an axis of rotation 35 of the intermediate carrier 54 including the assemblies carried by it, which is aligned coaxially with the pivot pin 57.
- the axis of rotation 35 of this arrangement can ultimately be shifted within relatively wide limits. This results in the in Figures 8 to 11 embodiment shown a rotational degree of freedom 33 which, as immediately in Figures 8 and 9 understandable, is shown beyond the flat material 15, so that a stable balance of the corresponding swivel joint is ensured in this way.
- the degree of freedom of rotation 33 lies parallel to at least one roller axis 41 of the rollers 40, which are supported by the roller carrier 48, or perpendicular to the material running direction 32 of the rollers 40 belonging to this material running direction 32.
- the degree of freedom of rotation 33 of the swivel joint of the exemplary embodiment located between the fork 52 and the intermediate carrier 54 also follows Figures 4 to 7 lies parallel to at least one roller axis 41 of the roller 40 carried by the roller carrier 48, insofar as the roller carrier 48 is aligned accordingly.
- Figures 4 to 7 lies parallel to at least one roller axis 41 of the roller 40 carried by the roller carrier 48, insofar as the roller carrier 48 is aligned accordingly.
- the aforementioned parallelism can be implemented in a complementary manner in that the degree of freedom of rotation 33 should be oriented perpendicular to the material running direction 32 of at least one roller carried by the roller carrier 48.
- roller support 48 is in each case on the intermediate support 54 via rotary guide surfaces 58 (in the exemplary embodiments according to FIG Figures 4 to 7 not explicitly shown) mounted, it being secured on the end face via side plates 56.
- a non-numbered pivot pin is arranged, which secures the roller carrier 48 in the intermediate carrier 54 and defines a rotational axis 35 with a degree of freedom of rotation 34, which is aligned parallel to the material running direction 32 on the rollers 40.
- the rolling forces of the rollers 40 which act successively on the flat material 15, are transmitted via the rotating guide surfaces between the roller carrier 48 and the intermediate carrier 54, and only a small part of these forces are absorbed by the pivot pin.
- the axis of rotation 35 of the degree of freedom of rotation 34 from the point of view of the rollers 40 also lies on this side of the flat material 15. This may lead to a somewhat more unstable equilibrium if rolling forces act on this arrangement. However, depending on the dimensioning of the rolling forces and the rollers, this may be tolerable.
- the roller carrier 48 is mounted on the intermediate carrier 54 via rotary guide surfaces 58
- the side plates 56 have securing links 59 which run in corresponding, not separately numbered securing grooves and secure the roller carrier 48 in its position on the rotary guide surface 58 of the intermediate carrier 54.
- the rotation guide surfaces 58 and the safety guideway of the safety link 59 can be freely selected within wide limits, so that in this exemplary embodiment the axis of rotation 35 of the degree of freedom of rotation 34 can be found beyond the flat material 15 from the perspective of the rollers 40.
- the rotational axis 35 of the rotational degree of freedom 34 is also aligned parallel to the material running direction 32 in this exemplary embodiment.
- the intermediate carrier 54 and / or the roller carrier 48 can be readily pretensioned in such a way that they tend to spring back into a correspondingly predetermined neutral position.
- springs can be mechanical springs, for example, which act parallel to the guide direction.
- compression springs or hydraulic or pneumatic arrangements can act on the intermediate carrier, for example at the front and rear, in order to require a corresponding setting behavior.
- Such spring means 60 can, however, also be implemented differently, for example by flat spiral springs, by pneumatic springs or by other resetting devices, and can also be provided with respect to the degree of freedom of rotation 34. It is also understood that corresponding spring means 60 also in the arrangement Figures 8 to 11 can be provided.
