Description

    Technical area
  • The invention relates generally to a device and a method for cold rolling profiling of variable height profiles, and more particularly to an apparatus and a method according to the preambles of claims 1 and 9.
  • State of the art
  • In industry, especially in the automotive industry V- or U-profiles are often used, for example, to stiffen the body, as a carrier or axles. These profiles often have a non-constant height or depth, and of course they do not have to be symmetrical. Examples of profiles with varying heights or depths are in the FIGS. 1A to 4C in which the FIGS. 1A to 1C show different views of a U-profile with lowering 1, the FIGS. 2A to 2C show different views of a U-profile with boost 2, the FIGS. 3A to 3C show different views of a U-profile with lowering and raising and constant leg height, and the FIGS. 4A to 4C show different views of a V-profile with lowering 1. As seen from the frontal view of Figures 1C . 2C and 3C can be seen, from which the course of the variable height between the lines 3 and 4 can be seen, the U-profiles shown therein have a constant width. The V-profile of Fig. 4C has a variable height and a variable width 33.
  • Conventionally, profiles of the type described above are made with pressing, so that any change in the length or shape of the profile brings a costly adaptation of the press with it.
  • In addition, "false" profiles of variable height are known in which the profile is flexibly profiled in width so that first the lateral small elements 5 are formed and then the long legs 6 are bent upwards, as in FIGS Figures 10A and 10B illustrated. With this approach, however, it is only possible to cover a very small range of profiles with variable heights.
  • From the DE 100 11 755 A1 are a device and a method for forming a profile by means of cold rolling profiling known, whereby profiles with variable over the length cross-sections can be produced by the Verstellgerüste not only moved transversely to the profile longitudinal direction during profiling, but also the roller tools each Verstellgerüstes over the entire profile length tangentially be positioned on the desired bending edge course of a profile. For this purpose, the adjusting frame in addition to the adjustment is made possible transverse to the profile longitudinal direction of rotation about a vertical axis to Blechbandzuführebene. In practice, however, this device is suitable only for the formation of profiles with variable width, since for profiles with variable height simultaneous movements should be performed in five degrees of freedom. For this purpose, a motor drive would have to be provided for each of these degrees of freedom, and each of these drives would have to be designed more powerful than the maximum deformation resistance to be overcome. In addition, the range of motion in each degree of freedom would have to be high, especially for profiles with larger ones Height variability, and the control would be very complicated. Accordingly, the formation of variable height profiles is not considered in this document. This also applies to a similar device coming out of the DE 10 2004 040 257 A1 is known.
  • From the US 5 722 278 A and from the WO 2007/008152 A1 are each a device and a method for forming a profile with variable height by cold rolling profiling according to the preambles of claims 1 and 9, respectively, with which the aforementioned problems are partially solved.
  • Disclosure of the invention
  • The object of the invention is to provide a device or a method with which or cost profiles can be produced, viewed over the length have a cross-section with variable height, the range of motion in each degree of freedom can be particularly small and the control can be very easy. Here, a relatively large range of profiles with variable heights to be covered.
  • This object is achieved in a generic device and the corresponding method by the characterizing features of claims 1 and 9, respectively. Advantageous developments of the invention are specified in the subclaims.
  • The invention is not limited to profiles of constant width and / or on V or U-profiles, especially since these can be advantageously used in conjunction with various symmetrical and asymmetric profiles of constant and variable width.

    Detailed description of the invention
  • With reference to the Fig. 5 Now is a perspective view of a Inventive device for cold rolling profiling of profiles with variable height described.
  • The term "variable height" is to be understood in the context of the application as meaning that the height of the profile varies as viewed along the longitudinal direction. The profile is also manufactured in such a way that the bottom of the finished profile does not run in one plane through the cold rolling profiling line, but the floor is lowered or raised. In addition, the profile of the FIGS. 3A to 3C a height-variable profile. The profile can of course also be made upside down.
  • The apparatus for cold rolling profiling comprises a unit (not shown) for cutting the sheet metal strip in width with, for example, laser beam, plasma, water jet, with rotatable and linear moving pairs of cutting rollers, Schnellstanzeinrichtung, nibblers or shears with short cutting length, the trimming also take place at the end can; a drive unit designated by reference numeral 7; a lowering / lifting unit designated by reference numeral 8; and a forming unit 9.
  • The apparatus for cold roll profiling may further comprise, upstream of the drive unit 7, the following not shown conventional generic components:
    • a decoiler, which is usually in the form of a reel, on which the flat sheet metal strip is wound;
    • a straightening unit for straightening the band;
    • a band memory, which is usually performed as a pit, to compensate for speed differences; and
    • a pre-punching unit with downstream strip storage.
  • The apparatus for cold rolling profiling may be downstream of the forming Unit 9 further comprises the following not shown conventional generic components:
    • a re-punching unit for forming beads, embossments or other apertures;
    • a welding machine, with closed and welded profiles;
    • Means for removing the overhang of the weld and for deburring;

    The flange ( - ) can be produced in a subsequent forming process. The station or stations use a combination of fixed and moving rollers. The side flanges are made with fixed rollers. The support on the ground is expediently carried out with pairs of rollers, which are also to move with two degrees of freedom.
  • The drive unit 7 comprises at least one stand 10 for driving the sheet-metal strip and at least one motorized gear 11, which drives corresponding rolls of the stand 10 via shafts 28. In the exemplified embodiment, two scaffolds are shown, however, it will be understood by those skilled in the art that the number of scaffolds can be increased or decreased as needed. The upstream of the lowering / lifting unit 8 arranged drive unit 7 has the function to prevent a possible lowering / raising a train from the rear and the change in length of the Align sheet metal strip in the lowering / lifting unit 8.
  • The FIGS. 6A to 6D show various possible embodiments of the lowering / lifting unit 8 of Fig. 5 , According to the invention, it is not absolutely necessary to provide the lowering / lifting unit 8, since the variable height profiles can be formed exclusively by using the forming unit 9. If the lowering / lifting unit 8 is used according to the invention, it offers certain advantages in connection with the forming unit 9 if deeper profiles of variable depth are to be formed and / or if the length of the forming unit 9 is to be limited.
  • Referring again to the FIGS. 6A to 6D For example, the lowering / lifting unit 8 can assume different configurations in order to realize a depression in the sheet metal strip to be profiled in such a way that the lowering or raising of the floor before the actual profiling is already introduced into the sheet metal strip.
  • One possible embodiment as 3-roll bending machines 12 is in the Fig. 6A 4 or 6 roller benders may be used, as will be understood by those skilled in the art. In the embodiment of Fig. 6A For example, the trough can be formed into the sheet metal strip by the arrangement of the roller pairs of the roll bending machines which are raised and lowered. But it can also be used three pairs of cylindrical rollers, which are raised and lowered to form the tape convex and concave before.
  • The design of the Fig. 6B is designed as a hydraulic press 13 with a suitable tool for lowering, so that a trough can be preformed in the sheet metal strip. This embodiment corresponds to that in the Fig. 5 shown unit 8.
  • The design of the Fig. 6C is formed as a pair of hydraulic presses 14 and 15 with a suitable tool for lowering or raising, so that a trough and an increase in the sheet metal strip can be preformed.
  • The design of the Fig. 6D is designed as a press 16 with rotating tool for lowering and lifting, preferably servo-hydraulic, to lower or raise the sheet metal strip with the press.
  • All of the presses shown above may be stored in a fixed or floating manner, depending on whether continuous or discontinuous profiling takes place. Referring again to the Fig. 5 in conjunction with the Figs. 7A and 7B the forming unit 9 will be described in more detail. The forming unit 9 is composed of a plurality of Verstellgerüsten 17 whose rollers (rollers) are driven by a respective motor 18 via a corresponding shaft 28. For simplicity, the motorizations of the first three adjusting stands are shown in FIG. 5A.
  • In the Fig. 7A is shown an adjustment frame 17 for the parallel kinematics, which is preferably designed as a bi-pod or duopod. The Duopod is more detailed in the German patent application DE 10 2007 011 849 A1 , the contents of which are incorporated herein by reference. The duopod allows two degrees of freedom through a translatory and a rotational movement. The translational degree of freedom is achieved by moving a roller stand (roll stand) 19 with a base plate 20 carrying two axially parallel rollers 22, between which an elongated gap exists, through which the sheet metal strip of length X is guided by rectified actuation of two push rods 21 , Thus, the translational movement takes place in the in Fig. 7A shown Z-direction. The rotary degree of freedom is realized by counteracted actuation of the two push rods 21, so that the roller stand 19 is rotated about the axis of rotation of the base plate 20, wherein the gap between the rollers 19 remains stationary. This axis of rotation is called the axis of rotation of the roll stand below. In the embodiments of the invention of Fig. 7 and 8th the axis of rotation of the roller stand 19 axis parallel between two rollers 22 For clarity, the coordinate system XYZ in the Fig. 5 plotted, wherein X indicates the Blechbandförderrichtung. The inventive arrangement described, the translational degree of freedom and the rotational degree of freedom are decoupled from each other.
  • By the translational movement of the roller stand 19 of the bi-pod or duopod 17 of Fig. 7A The edges of the sheet metal strip can be raised, so that ultimately creates a profile with a variable height or depth. If only a translatory movement of the roller stand 19 in the Z-direction is possible and the axis of rotation of the roller stand 19 is parallel to the Y-axis, a profile with a constant width is produced.
  • By the rotational movement of the roller stand 19 of the Bi-Pod or Duopod 17 of Fig. 7A For example, during cold rolling profiling, the rollers 22 can be pivoted together about the axis of rotation of the roller stand 19, so that the rollers 22 are moved tangentially to the surface of the sheet metal strip. Therefore, in this mode of operation of the bi-pod or duopod 17, an unwanted collision between the rollers 22 and the surface of the sheet-metal strip is avoided. However, it may also be desired in certain embodiments, the forces resulting from a collision in order to press more vigorously on the surface of the sheet metal strip, so that an additional reduction or increase is achieved. Control of the Bi-Pod or Duopod 17 can be achieved by using a COPRA Adaptive Motion control from the home of the applicant done. By virtue of the bi-pod or duopod 17 of the device of FIG. 5A, it is advantageously possible to produce V- or U-shaped profiles with variable height or depth. However, only profiles with constant width can be produced.
  • The adjustment frame 17 of Fig. 5 or 7A can be replaced by an adjustment stand 17 'for the parallel kinematics, which also profiles with variable height and variable width can be made both U- and V-profile. Such a Verstellgerüst 17 'is in the Fig. 7B in which deviates from the Fig. 7A the push rods 21 are replaced by a pair of guides 23 which sit on a common plate. Thereby, the base plate 20 of the rollers 22 can be pivoted at an adjustable angle in the YZ plane. The mechanism for adjusting the angle for the guides 23 is indicated schematically by reference numeral 24 in FIG Fig. 7B and requires no further explanation for the expert.
  • In addition, the position of the base plate 20 can be adjusted along a circular arc 25, whereby a further degree of freedom is achieved, so that it, for example, as in connection with the Fig. 8 explained, it is possible to align the axes of the rollers 22 parallel to the Y direction despite the inclination of the guides holding the guides 23.
  • The adjusting frames 17 'are, as in the Fig. 8 shown, arranged in pairs successively staggered, with a pair of Verstellgerüsten 17 'forms a bending station of the forming unit 9.
  • In principle, the adjusting stands 17 and 17 'can be operated to produce profiles of variable height and constant width or profiles of variable height and variable width.
  • For the production of profiles with variable height and constant width, the inclination of the guides 23 holding plate is adjusted vertically, so that the adjusting frames 17 'act similar to the adjusting frames 17.
  • For the production of variable height, variable width profiles, the inclination of the plate holding the guides 23 must be adjusted independently for each pair of bending stations to follow the angle of inclination of the edges of the strip. This means that the inclination of the plate 23 holding the guides should follow the changing angle of inclination of the edge to be bent for each bending station pair. It is understood that in the case of profiles with variable height and variable width, the inclination is less than 90 °. According to the invention, the adjustment of the inclination of the guides 23 holding plate is carried out either in exact accordance with the inclination angle of the edge to be bent or by the inclination of this plate in addition, taking into account the centric stretch, as in connection with the FIGS. 9E to 9H explained, corrected. The variable width of the profile is achieved at each bending station pair by the method of the base plate 20 on the inclined guides 23, so that the distance between the roller pairs 22 to the central longitudinal axis of the sheet metal strip (its longitudinal center line in the Blechbandförderrichtung) changed. At the same time, the variable depth is produced by this movement of the roller pairs 22.
  • By means of the adjustment framework 17 'explained above, a translatory movement or a degree of freedom in the YZ plane is possible. The rotational movement or the degree of freedom of Verstellgerüstes 17 'can by the operation of a lever by a linear drive, not shown, analogous to the above DE 100 11 755 A1 be realized and will therefore not be explained here.
  • In the event that with the adjustment frame 17 'symmetrical V or U-profiles with variable height and constant width to be produced, the control is analogous to that of the Verstellgerüstes 17, wherein the translational movement takes place in the Z direction and the rotational movement is also implemented by rotating the base plate 20 about its axis of rotation. Also in this case, the control can be such that unwanted collisions between the pairs of rollers 22 and the surface of the sheet metal strip can be avoided, or it is intentionally caused a collision of the roller pairs 22 with the surface of the sheet metal strip to deform these in addition.
  • In the event that symmetrical or asymmetric V- or U-profiles with variable height and variable width are to be produced with the adjusting frame 17 ', in addition a displacement of the adjusting frame 17' in the Y-direction perpendicular to the Z-direction and Blechbandförderrichtung must X are introduced, for example, by the displacement of the base plate 20 along the inclined guides 23, wherein in the case of symmetry, the displacement of Verstellgerüste 17 'in the Y direction in pairs is equal and in the case of asymmetry, this shift is unequal. In other words, in the case of asymmetry, the guides 23 or the holding plates of a pair of adjusting stands 17 'of a bending station must have different angles of inclination.
  • As already explained, the device according to the invention can be operated with or without a lowering / lifting unit 8.
  • In the case of operation with a lowering / lifting unit 8, only a remainder of the profile or the lateral edges of the profile are produced in the forming unit 9. In this case, the pairs of rollers according to the preformed profile (trough or increase) are translationally raised and lowered and order an axis rotated rotationally. In this operating mode with lowering / lifting unit 8, all adjustable scaffolds can be mounted and adjusted in parallel. The translational movement takes place in the operating mode with lowering / lifting unit 8 parallel to the end cross section of the sheet metal strip. The course of the profile flowers in the above operating mode is in the FIGS. 9A to 9D illustrated, wherein the solid line shows the normal cross-section and the dashed line the height-changed cross-section. In particular, the shows Fig. 9A the superposition of cross sections in the final shape of the profile, the Fig. 9B shows the profile flower of the normal cross section, the Fig. 9C shows the profile flower of the height - changed cross section, and the Fig. 9D shows the superimposition of the profile flowers of the Figs. 9B and 9C ,
  • In the case of operation without lowering / lifting unit 8, the roller pairs are moved up and down according to the desired profile, and they profile the bottom and the cross section of the sheet metal strip in several forming steps to the finished product with variable height.
  • In the particular case of operation without lowering / lifting unit 8, in which the profile is variable both in height and in width, as already mentioned, the adjustment of the inclination of the guides 23 holding plate either in exact accordance with the inclination angle of the edge to be bent or by the inclination of this plate is corrected taking into account the centric extension.
  • The adjusting frames 17 and 17 'of FIGS. 7A and 7B are similar in that the axes of the roller pairs 22 extend in the same direction, namely parallel to the Blechbandzuführebene X, Y and in particular parallel to the Y direction.
  • However, the inventors of the present application have learned that particular advantages with the modified Verstellgerüsten the FIGS. 7C and 7D can be achieved.
  • The Fig. 7C represents a variant of the Verstellgerüstes Fig. 7A represent, wherein like parts are identified by the same reference numerals. The adjusting frame 17 "of Fig. 7C has deviating from the adjustment frame 17 of Fig. 7A the mechanism 24 of the Verstellgerüstes 17 ', whereby the angle of the base plate 20 is adjustable in an oblique direction to the XY plane. The rollers 22 are no longer easily rotatable over shafts in view of the adjustability of the base plate 20, and therefore their motorization is integrated into the roller stand (rolling stand) 19, as indicated by reference numeral 18 " Form of a servo motor, an asynchronous motor, a motor with frequency converter or the like can be implemented and therefore needs no further explanation.
  • In the embodiment of Fig. 7C For example, the pair of rollers 22 may be displaced from a position in which the axes of the rollers 22 are parallel to the sheet conveyance plane X, Y to a position in which these axes are perpendicular to the sheet conveyance plane X, Y. Thus, the rotational degree of freedom of the adjusting frame 17 "lies in a plane that can be pivoted from a position substantially perpendicular to the sheet metal belt conveying plane X, Y into a position lying substantially parallel to the sheet belt conveying plane X, Y. Consequently, it is possible to use sheet metal belts with a variable Width to process, unless the axes of the roller pairs 22 are not parallel to the sheet metal conveyor plane X, Y, wherein the resulting bottom of the sheet metal strip is basically uneven and is adjustable on the roll geometry.
  • The Fig. 7D represents a variant of the Verstellgerüstes Fig. 7B represent, wherein like parts are identified by the same reference numerals. The adjusting frame 17 "'of the Fig. 7D has a suitable motor 18 '', the analogous to the engine 18 "of Fig. 7C is integrated into the roller stand 19. Because of the lack of waves 28, the position of the base plate 20 along the circular arc 25 can be adjusted without any restrictions in this regard, so that analogous to the configuration of the adjustment of the Fig. 7C in case of Fig.7D It is also possible to move the roller pair 22 from a position in which its axes are parallel to the sheet metal conveyor plane X, Y, to a position in which its axes are perpendicular to the sheet metal conveyor plane X, Y. This results in a mode of action that of the Verstellgerüstes the Fig. 7C is analog.
  • Both the adjusting frames 17 "of Fig. 7C as well as the adjusting frames 17 "'the Fig. 7D can, as in the Fig. 8 shown to be arranged in pairs one behind the other.
  • The FIGS. 9E to 9H show the course of the profile flower with a correction of the inclination of the guides 23 holding plate depending on the central extension at the bending point of the sheet, wherein the solid line shows the normal cross-section and the dashed line the height-changed cross-section. In particular, the shows Fig. 9E the superposition of cross sections in the final shape of the profile, the Fig. 9F shows the profile flower of the normal cross section, the Fig. 9G the profile flower of the height-changed cross-section and the Fig. 9H the overlay of the profile flowers of the Figs. 9F and 9G , Like from the Figs. 9G and 9H can be seen, thanks to the centric extension dependent correction of the bottom of the profile is lowered or raised in approximately equal steps. The FIGS. 9I to 9L correspond to the FIGS. 9E to 9H with the difference that no correction depending on the centric extension has been carried out, and accordingly the lowering of the bottom of the profile takes place in different non-linear steps, which leads to an increase of the tension with respect to the embodiment with the centric extension dependent correction leads.
  • The roles of a roller stand are cylindrical in their simplest form and axis-parallel, as in the above DE 100 11 755 A1 shown, and the axis of rotation of such a roller stand is perpendicular to the direction of movement or perpendicular to the direction of the variability of the profile cross-section.
  • The roles of a roller stand but need not be cylindrical, but they can have variable in diameter over their length, as in the Figures 5 . 7 and 8th shown to provide the sheet metal strip partially with a specific profile. In this case, the axis of rotation of the roller stand is also perpendicular to the direction of movement or perpendicular to the direction of the variability of the profile cross-section.
  • The latter formulation should also include the case that the rollers of a roller stand are not axis-parallel, but that their axes are more or less inclined to each other. This may be necessary to prevent or reduce collisions.
  • The FIGS. 11A to 11D show some of many possibilities for the construction and arrangement of two rolls of a roll stand. It shows Fig. 11A a classic, ie axis-parallel and inventive arrangement of the rollers with complementary variable diameters, which pass a metal strip between them; Fig. 11B shows a non-inventive arrangement in which the axis of a roll is parallel to the Blechbandzuführebene and the axis of the other roll is inclined to Fig. 11C shows a non-inventive arrangement in which the axes of the rollers are not only inclined to each other, but are offset from each other in the Blechbandförderrichtung; and Fig. 11D shows a non-inventive arrangement in which the axes of the rollers inclined to each other, offset in the Blechbandförderrichtung against each other and additionally rotated about the vertical axis (a more or less radially through both rollers line) against each other.
  • When technical features mentioned in any of the claims are provided with a reference numeral, these reference numerals have been included only to enhance the intelligibility of the claims. Accordingly, these reference numbers have no limiting effect on the scope of protection of each element, which is exemplified by such reference numerals.
