Description
PROCEDURE FOR ASSEMBLING EDGES AND / OR SURFACES OF A PROFILE, ARRANGEMENT OF ASSEMBLY ROLLERS AND INSTALLATION OF PROFILING The invention relates to a method for assembling edges and / or surfaces of a profile in a roll forming installation for the longitudinal shaping of a strip of material or profile, so to speak, endless, into a profiled shape that is at least partially closed according to the preamble of claim 1. The invention also relates to an arrangement of assembly rollers for carrying out the method, a flat assembly arrangement for carrying out the method, and a roll forming installation according to the preamble of claim 14. In a process of this type, a strip of material, a blank, or a profile is formed into a self-contained or partially enclosed profiled shape in a roll forming machine by means of a plurality of roller forming tools. This profiled shape is then fixed in an assembly area of the roll forming machine by an assembly process, such as, in particular, brazing, soldering, gluing, or folding, along the longitudinal extent of the profile, forming a longitudinal assembly seam. In this respect, the profile in the assembly area passes through an assembly roller arrangement and / or a flat assembly arrangement to feed the profile to an assembly point in a controlled manner and, in particular, to stabilize it at the assembly point and / or ensure that the profile remains dimensionally stable during and after assembly.In this sense, a stable assembly seam must be formed. This process utilizes a roll forming installation of this type, which includes a plurality of roller forming tools to successively shape the strip of material or profile, or the blank, into a self-contained or partially enclosed profiled shape. It also features, in an assembly area, an assembly device for fixing the self-contained or partially enclosed profile at an assembly point by an assembly method, such as, in particular, brazing, soldering, gluing, or folding, along the longitudinal extent of the profile, forming a longitudinal joining seam.In the assembly area there is an assembly roller arrangement and / or a flat assembly arrangement to feed the profile to the assembly point in a controlled manner and, in particular, to stabilize it at the assembly point and / or ensure that the profile remains dimensionally stable during and after assembly. A roll forming plant typically produces a virtually endless array of cross-sectional profiles from a metal strip, where the term "profile" should also include tubes. Depending on the desired shape, a large number of roller forming tools are used, usually grouped into 20 to 30 forming stations arranged sequentially in a line. These stations successively shape the desired metal profile through gradual cold forming. The starting material is usually a metal strip, but it can also be blanks or pre-formed profiles, which are shaped in the roll forming plant to create the desired profile. If closed tubes or profiles, or even partially closed profiles, are manufactured in a roll forming plant, the edges and / or surfaces of the profile that lie longitudinally against each other or overlap each other when the profile is closed must be joined in a joint area. Various joining methods are used for this purpose, including brazing, soldering, and gluing as form-form joining methods, as well as bending, flanging, and similar methods. A longitudinal joining seam is thus created along the longitudinal length of the profile, thereby securing the profile. In an assembly zone of this type, there is usually an assembly roller arrangement, which can also be replaced or supplemented by a flat assembly arrangement. In this way, the profile is fed to an assembly point in a controlled manner and, in particular, stabilized at the assembly point. The assembly roller arrangement and / or the flat assembly arrangement generally not only ensure that the profile is stabilized at the assembly point, but also that the profile can be hardened under controlled conditions and that the profile is dimensionally stable during and after assembly. A flat assembly arrangement within the meaning of the present invention should generally be understood as an arrangement that not only—like assembly rollers—makes linear contact with the continuous profile, but touches the profile with a larger flat contact area that moves along with the profile. Therefore, a flat assembly arrangement according to the present invention may consist of a series of assembly rollers around which a flexible belt, link belt, or link chain is wound, particularly as in the case of a conveyor belt. It may, for example, be a chain-like structure in which several assembly rollers are wound in the direction of a track on a crawler vehicle. To optimize the readability of the description of the present invention, henceforth only the assembly roller arrangement and the assembly rollers are explicitly mentioned when referring to an assembly roller arrangement and / or a flat assembly arrangement, as well as to the assembly rollers and / or parts of the flat assembly arrangement. The assembly roller arrangements for a roll forming process and installation of this type are generally monitored geometrically, with the position of the individual assembly rollers adjusted manually or by motor. Evaluating the correctness of the roller positions, and in particular their fine-tuning, is the responsibility of the roll forming installation operators, and the quality of the results and any readjustment of the roller positions that may be necessary during operation generally correlates with the experience of the responsible operators. It is clear that the reproducibility and quality assurance of results, which depend on operator experience, often need optimization. Furthermore, operators with extensive experience in setting up and readjusting assembly roller arrangements are generally unavailable on-site when process parameters fluctuate due to variations in the quantity and quality of the profiled materials and changes in the process environment. i ιζβ / η / ζζηζα / γίΛΐ If the arrangement or positions of the assembly rollers are not correct, poor work results may occur, for example, because the assembly seam breaks again after the assembly area or because of deformations of the profile being joined until the geometry of the profile is destroyed. Especially in the case of material joining procedures such as brazing and gluing, it is also crucial for the quality and durability of the joint seam that the geometric arrangement or position of the joining rollers is also correct in a stabilization zone after the joining point, in which the joint seam cools or hardens in a controlled manner and only thus obtains the necessary quality and durability. Therefore, the invention is based on the objective of proposing a procedure for assembling edges and / or surfaces of a profile in a roll forming installation, as well as a roll forming installation of the type mentioned at the beginning, an arrangement of assembly rollers and / or a flat assembly arrangement, with which or with which a high-quality assembly seam can be produced as far as possible regardless of the experience and skill of the operators. This objective is achieved by means of a procedure with the characteristics of claim 1, by means of an assembly roller arrangement with the characteristics of claim 10, by means of a flat assembly arrangement with the characteristics of claim 12, as well as by means of a profiling installation with the characteristics of claim 14. Preferred refinements of the process according to the invention are found in claims 2 to 9. Claim 11 contains a preferred configuration of the assembly roller arrangement according to the invention, while a preferred refinement of the flat assembly arrangement according to the invention is the subject of claim 13. Claims 15, 16 and 17 define advantageous configurations of the profiling installation according to the invention. The process according to the invention, in which the strip of material, the blank, or the profile is shaped in the profiling installation into a self-contained or partially enclosed profiled shape by means of a plurality of roller forming tools, and this profiled shape is fixed in an assembly area of the profiling installation by means of an assembly process along the longitudinal extension of the profile, forming a longitudinal assembly seam, wherein the profile in the assembly area passes through an arrangement of assembly rollers and / or a flat assembly arrangement to feed the profile to an assembly point in a controlled manner and, in particular, to stabilize it at the assembly point and / or to ensure that the profile remains dimensionally stable during and after assembly, is therefore improved with respect to the prior art.such that in the assembly area forces or magnitudes of force components acting on the profile are detected from at least one of the assembly rollers and / or from at least one subsection of the flat assembly arrangement. The proposed assembly roller arrangement according to the invention for carrying out this procedure is characterized in that at least for one assembly roller there is a transducer that determines at least one force component of the force acting on the continuous profile from this assembly roller. The flat assembly arrangement according to the invention for carrying out the procedure is further characterized by at least one transducer that determines at least one force component of the force acting on the continuous profile from a part of the flat assembly arrangement. The profiling installation according to the invention, comprising a plurality of roller forming tools for successively shaping the strip of material or profile, or the blank, into a self-contained or partially enclosed profiled shape, and being provided with an assembly device in an assembly zone for fixing the self-contained or partially enclosed profile at an assembly point by means of an assembly procedure in the longitudinal extension of the profile forming a longitudinal joining seam, there being an arrangement of assembly rollers and / or a flat assembly arrangement for feeding the profile to the assembly point in a controlled manner and, in particular, for stabilizing it at the assembly point and / or ensuring that the profile remains dimensionally stable during and after assembly,It is modified i ιζβ / η / ζζηζα / γίΛΐ compared to the prior art in that the assembly roller arrangement and / or the flat assembly arrangement cooperates with at least one transducer to detect forces or magnitudes of force components acting on the profile from at least one of the assembly rollers or from at least a part of the flat assembly arrangement. The present invention is therefore based on the finding that the position of the assembly rollers in the assembly roller arrangement (or the positioning of the flat assembly arrangement) is not primarily responsible for the quality and success of the assembly operation, but rather the pressure exerted on the profile resulting from the geometric approximation or the position of the assembly rollers. Depending on the assembly procedure, it is also crucial, as recognized according to the invention, how the clamping pressure is distributed in a stabilizing zone behind the actual assembly point, acting on the newly assembled profile. If the local or overall pressure is insufficient, the assembly parts are not pressed together enough, and the joint seam may break again.If the pressure on the profile is too high, there is a risk of profile deformation and destruction of the profile's geometry itself, as well as poor assembly results. The present invention is based on the principle of monitoring and controlling the process forces acting on the assembly rollers (and / or the flat assembly arrangement) during assembly and, where applicable, also after assembly. In this respect, the process forces should be correlated with the contact pressures acting on the profile in the assembly area. By shifting the focus away from the position of the assembly rollers and focusing on the forces exerted by the assembly rollers on the profile, which are measured in such a way that they correlate with the contact pressures acting on the profile, it is possible to automate the assembly process and, in particular, make it independent of the experience of the operators, also providing inexperienced operators with the parameters with which they can optimize the positioning of the assembly roller arrangement (or the flat assembly arrangement). According to a preferred embodiment of the procedure described in the invention, the contact pressures acting on the profile from at least a portion of the assembly rollers and / or the flat assembly arrangement in at least one spatial direction are determined by detecting the forces acting on the profile at the assembly point and / or within the assembly area. The procedure thus directly provides the quantity that, as recognized in the invention, is ultimately important for the quality of the assembly process. The contact pressures acting on the profile in the assembly area can be regulated at least in part according to the forces or force components detected according to the invention by adjusting at least one assembly roller in the assembly roller arrangement and / or at least a part of the flat assembly arrangement. Therefore, not only is automation of the adjustment of the assembly roller arrangement possible, but it can also be automatically identified and, where appropriate, adapted if, for example, the quality of the profile material or its geometry or quantity, in particular the material thickness or material width, varies. The contact pressures acting on the profile from the assembly rollers and / or from the flat assembly arrangement are preferably regulated in this direction at the assembly point and / or behind the assembly point to ensure the quality of the work result. For regulating the contact pressures within this preferred embodiment of the process according to the invention, other process parameters can also be taken into account, in particular the actual positions of the profile areas to be assembled, or the positions of the assembly rollers or any other clamping rollers or additional clamping structures that may be present. This requires sensors to detect the positions, but this effort can be justified, as the working results can be optimized in this way depending on the profile shape. Another preferred configuration of the process according to the invention involves the profile passing through a stabilization zone after the assembly point within the assembly zone to stabilize the joint seam by cooling and / or hardening. This is particularly essential for material joining processes such as brazing and gluing. In this regard, a portion of the assembly roller arrangement and / or the flat assembly arrangement serves to stabilize the profile in the stabilization zone, and according to the invention, the forces acting on the profile from at least one of the assembly rollers and / or at least a portion of the flat assembly arrangement in the stabilization zone are detected. This improvement of the procedure according to the invention implements the finding that not only the contact pressure acting on the profile at the actual assembly point is decisive for the outcome of the work, but also the contact pressures in a stabilization zone arranged downstream in which the joint seam cools and / or hardens and thus acquires its strength. By configuring the assembly roller arrangement and / or the flat assembly arrangement, according to another preferred configuration of the method according to the invention, the specifications for the contact pressures and / or forces acting on the profile in the assembly area can be used as target values. This also helps and trains less experienced operators to configure the assembly roller arrangement or the flat assembly arrangement to achieve a good assembly result. To identify variations in process conditions and issue at least one warning if variations are detected, the forces acting on the profile from at least one of the assembly rollers and / or at least a portion of the flat assembly arrangement can be continuously detected within the assembly roller arrangement and / or the flat assembly arrangement as part of the procedure according to the invention. This warning prevents rejects even if there is no experienced operator on site who can react quickly and appropriately to a variation in process conditions, or if a variation in process conditions is not easily identifiable. Finally, as an additional advantageous configuration of the process according to the invention, the target values for the forces acting on the i ιζβ / η / ζζηζα / γίΛΐ profile in the assembly zone can be continuously optimized with the aid of machine learning algorithms. It is particularly advantageous that these algorithms include access to additional information detected upstream or downstream in the process. Upstream, this could be, for example, the detection of the width of the fed sheet metal strip. Downstream, quality assurance systems can be used, for example. Examples of such systems are eddy current measuring devices for evaluating weld seams, optical measuring devices for measuring assembly points (e.g., to detect a dip or rise in the seam), or geometric measuring systems for detecting the cross-section of the profile.Machine learning algorithms can correlate the quality characteristics detected in this way with the process magnitudes detected in the assembly area, readjust them, and continuously adapt and optimize the underlying control rules. The assembly roller arrangement according to the invention or the flat assembly arrangement according to the invention for carrying out the procedure described and claimed herein is preferably improved in that at least one assembly roller of the assembly roller arrangement or at least a part of the flat assembly arrangement can be motor-adjusted, wherein a controller is operatively connected to the assembly roller arrangement or the flat assembly arrangement and to the transducer in order to regulate at least partially the contact pressures acting on the profile in the assembly area according to the forces detected by adjusting at least one assembly roller in the assembly roller arrangement or at least a part of the flat assembly arrangement. The profiling installation according to the invention can be improved within the scope of the present invention in that at least one assembly roller of the assembly roller arrangement and / or at least a portion of the flat assembly arrangement can be motor-driven, wherein a controller is operatively connected to the assembly roller arrangement and / or the flat assembly arrangement and to the transducer in order to regulate at least partially the contact pressures acting on the profile in the assembly area based on the detected forces by adjusting at least one assembly roller in the assembly roller arrangement and / or at least a portion of the flat assembly arrangement. In this way, the advantages and effects already described for the process according to the invention are obtained. i ιζβ / η / ζζηζα / γίΛΐ If the profiling installation according to the invention is equipped with a flat assembly arrangement in the assembly area, it may ultimately be advantageous for the contact pressure of the flat assembly arrangement to be generated by means of pneumatic cylinders acting on the structure in a chain-like fashion. Because, in conjunction with a flat assembly arrangement, which may be configured as a chain-like structure within the framework of the present invention, designed, for example, in particular like the tracks of a tracked vehicle, the spring-like properties of the pneumatic cylinders can prove advantageous. The following are examples of implementing a profiling installation, an assembly roller arrangement according to the invention, or a flat assembly arrangement according to the invention, which also describe an exemplary procedure designed according to the present invention, with reference to the accompanying drawings. They show: Figure 1 is a schematic representation of a roll forming installation that is designed or can be designed according to the invention; Figure 2 is a schematic representation of an assembly roller arrangement designed according to the invention, during the process; Figure 3 is a schematic representation of an assembly roller arrangement designed according to the invention with corresponding clamping structures in the roll forming installation; Figure 4 is a schematic representation of an example process of a material joining assembly in an assembly roller arrangement according to the invention; Figure 5 is a schematic representation of an example process of a form drag assembly in an assembly roller arrangement designed according to the invention; Figure 6 is a schematic representation like that in Figure 2, but of a combined assembly roller arrangement and flat assembly arrangement; Figure 7 shows a plan view of the assembly roller arrangement according to Figure 3, but modified to provide for a flat assembly arrangement in the form of a chain-like structure. Figure 1 shows a schematic side view of a roll forming installation. In this installation, a seemingly endless strip of metal material 1 is successively shaped into a profile by means of a plurality of roller forming tools 2, which in this case are grouped into 16 forming stations 3. For this purpose, the strip of material 1 is unwound from a coil 5 onto a winder 4, guided through a straightener 6 and a loop 7 before being continuously and successively longitudinally shaped in the forming stations 3 into the desired profile. Following the 16 forming stations 3, the strip of material 1, or the profile already formed into a closed profile shape, passes through an assembly area 8. In this assembly area 8, a welding device 9 closes the profile by brazing at an assembly point 10.In the assembly zone 8, around and downstream of the assembly point 10, there is (shown here only schematically) at least part of an assembly roller arrangement 11 to ensure that the weld seam is assembled under controlled conditions and can harden in a controlled manner in the closed profile 14. The material strip 1 or the finished closed profile 14 then passes through two further forming stations, which act as calibration stations 12, before being cut to length into individual hollow profiles of the desired length at a cutting station with a simultaneously operating crosscutting saw 13. Figure 2 shows a schematic representation of the assembly roller arrangement 11 of Figure 1, which is arranged on and downstream of the welding device 9. At this point, it should be noted that it is also within the scope of the present invention that the assembly roller arrangement 11 is positioned directly at the assembly point 10, depending on the assembly procedure, or that it is not only arranged downstream of the assembly point 10, but may also be arranged extending beyond the assembly point 10. The strip of material 1, which has already been shaped into a closed profile 14, is passed between three pairs of assembly rollers 15 in the assembly roller arrangement 11 shown in Figure 2. A seam 16, produced by the welding device 9, is visible on the upper side of the profile 14. This seam 16 must first cool and solidify before it becomes stable. During this time, the profile is guided between the assembly rollers 15 in such a way that the seam 16 cannot open or be subjected to excessive pressure. To achieve this, the assembly rollers 15, as indicated by the double arrows 17, can be adjusted toward and away from the profile 14.According to the invention, the assembly rollers 15 are monitored, preferably in an adjustment mechanism (not shown), by means of force sensors to detect the forces acting on the profile from the assembly rollers 15, at least those force components that contribute significantly to loading or relieving the load on the assembly seam 16. A possible assembly point 10 is indicated here by the reference number 10 in parentheses, since it can also be located between the first pair of assembly rollers 15, i.e., the laser beam of the welding device 9 acts on the profile 14 at this assembly point 10 and, in this respect, the arrangement of assembly rollers 11, unlike what has been shown in Figure 1, extends over the entire assembly area 8, i.e., it is also present at the assembly point 10. Figure 3 shows an alternative embodiment of the assembly roller arrangement 11 in a less schematic representation with some details. The profile 14 is again stabilized here between two pairs of vertically oriented cylindrical assembly rollers 15, with two further assembly rollers 18 acting on the two upper edges of the profile 14, which has an approximately rectangular cross-section, in order to further stiffen the assembly seam 16 under controlled conditions. The details in Figure 3 are intended to clarify the adjustment mechanism of the adjustable assembly rollers 15, 18: The position of each of the individual assembly rollers 15, 18 can be varied by means of clamping plates 19, spindles 20, and adjusting wheels that can be operated by motor or manually. As shown in Figure 3, the additional assembly rollers 18 can be adjusted in this way both vertically and horizontally. The force sensors or transducers required for detecting forces or force component magnitudes in the assembly area, according to the invention, can be placed at a wide variety of points on the adjustment mechanism, for example, on clamping plates 19, adjusting wheels 21, assembly roller shafts 15, spindles 20, side guides, and the like. The evaluation of current signals from optionally present adjusting motors can also be used to evaluate forces or force components. Figure 4 again shows the basic structure of the assembly roller arrangement 11 of Figure 3 in a very schematic representation. The profile 14 with the assembly seam 16 is held in a defined state between the adjustable assembly rollers 15 and the additional, equally adjustable assembly rollers 18, which act on the upper edges of the profile 14. The positions of the assembly rollers 15 and 18 are selected according to the invention by monitoring forces and force components and, if necessary, readjusted or regulated, so that the assembly seam 16, which in this case is a weld seam, can be hardened under controlled and reproducible conditions. Figure 5 shows a schematic representation similar to that in Figure 4, but of a different embodiment: In this case, profile 14 is a tube with a substantially circular cross-section, and the joint seam 16 is not produced by brazing, but by bending and, if necessary, subsequent soldering. The bending is carried out by means of two specially designed assembly rollers 15; the assembly point 10 is shown in cross-section here. The two assembly rollers 15 can be moved closer together or further apart to form the joint seam 16 at this point, shaping profile 14 to a greater or lesser extent. According to the invention, the forces exerted by the assembly rollers 15 on the profile 14 at the assembly seam 16 are detected again, so that the assembly rollers 15 can always be positioned in such a way that the assembly seam 16 is neither excessively weakened nor subjected to excessive load from the forming forces. The corresponding forces or force components can be detected very easily, for example, by means of transducers on the shafts or axles (not shown) of the assembly rollers 15. Figure 6 shows another example of the hardening, controlled according to the invention, of the joint seam 16 in the profile 14, with the help of a representation that largely coincides with Figure 2. Consequently, identical elements are provided with identical references. The profile 14 with the newly produced brazed joint seam 16 passes through three pairs of joint rollers 16, whose relative positions can be adjusted in each case with respect to the profile 14, and the profile 14 is held or transported between these pairs of joint rollers 15 with monitored forces according to the invention, acting on the profile 14 and, in particular, on the joint seam 16. A chain-like structure 23, similar to a conveyor belt, is in this case wound around the joint rollers 15 on each side of the profile 14, so that from the joint roller arrangement 11 a flat joint arrangement 22 is obtained as a result.This is because the chain-like structure 23 distributes the forces acting on the profile 14 from the assembly rollers 15, which are transmitted via linear contact in the embodiment shown in Figure 2, over a surface. This provides gentler treatment for a profile 14 made of sensitive material, such as aluminum, or with a sensitive surface. The forces ultimately acting on the assembly seam 16 can also be distributed more evenly in the flat assembly arrangement 22 by means of the chain-like structure 23. The surface of the chain-like structure 23 also moves along with the profile 14, thus protecting the profile 14's surface. The assembly rollers 15 of the flat assembly arrangement 22 shown in Figure 6 can also be wrapped with a flexible tape, a link tape, or a link chain, instead of with the chain-like structure 23. Finally, Figure 7 shows a schematic plan view of an assembly roller arrangement 11 according to Figure 3, where, however, downstream of the additional assembly rollers 18, a flat assembly arrangement 22 has been further combined with them. This flat assembly arrangement 22 is in turn formed by assembly rollers 15 wrapped with a chain-like structure 23 in the direction of the track of a crawler vehicle, in this case to protect the sensitive surfaces of the profile 14 (not shown here) and to distribute the clamping pressure over the profile 14 as flat as possible when the assembly seam 16 hardens. The two assembly rollers 15 shown on the left in the figure are responsible for feeding the profile 14 to the assembly point 10, which is located between the two additional assembly rollers 18. The assembly seam 16 is then hardened in a stabilization zone 24 where the profile 14 is held and guided by the flat assembly arrangement 22 and, according to the invention, by monitoring the forces exerted by the flat assembly arrangement 22, can be hardened under controlled conditions.
