- 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 are produced exclusively by using the forming unit 9 can be formed. 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.
- the lowering / lifting unit 8 may take on various configurations to realize a depression in the sheet metal strip to be profiled such that the lowering or raising of the floor prior to the actual profiling already introduced into the sheet metal strip.
- FIG. 6A One possible embodiment as 3-roll bending machines 12 is shown in FIG. 6A, wherein, as understood by the person skilled in the art, 4- or 6-roll bending machines can also be used.
- the trough may 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.

- FIG. 6D is designed as a press 16 with a rotatable tool for lowering and lifting, preferably servo-hydraulic, in order to lower or raise the sheet metal strip with the press.
- 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.
- the motorizations of the first three adjusting stands are shown in FIG. 5A.
- FIG. 7A shows an adjusting structure 17 for the parallel kinematics, which is preferably designed as a bi-pod or duopod.
- the duopod is described in more detail in 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 ,
- the rotary degree of freedom is realized by counteracted actuation of the two push rods 21, so _ _
- 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.
- the axis of rotation of the roller stand 19 axis parallel between two rollers 22, but it can also more or less obliquely to run, as will be explained later by way of examples, in which case, the gap between the rollers 22 displaced slightly while the roller stand 19 is rotated.
- the coordinate system XYZ is shown in FIG. 5, where X indicates the Blechbandf ⁇ rderides.
- the edges of the sheet-metal strip can be raised, so that ultimately a profile with a variable height or depth is formed. 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.
- the rollers 22 Due to the rotational movement of the roller stand 19 of the bi-pod or duopod 17 of FIG. 7A, the rollers 22 can be pivoted together during cold rolling profiling around 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 means of the bi-pod or duopod 17 of the device of FIG. 5A, it is advantageously possible to produce V-shaped or U-shaped profiles with variable height or depth. However, only profiles with constant width can be produced.
- the adjusting frame 17 of FIG. 5 or 7 A can be replaced by an adjusting frame 17 'for the parallel kinematics, whereby profiles with variable height and variable width can be produced as both U- and V-profile.
- Such an adjustment frame 1 T is shown in Fig. 7B, wherein, in contrast to 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 shown schematically by the reference numeral 24 in FIG. 7B and needs no further explanation for those skilled in the art.
- the position of the base plate 20 along an arc of a circle 25 can be adjusted, whereby a further degree of freedom is achieved, so that it is possible, for example, as explained below in connection with FIG. 8, despite the inclination of the guides 23 holding plate to align the axes of the rollers 22 parallel to the Y direction.
- the adjusting frames 1 T are, as shown in FIG. 8, arranged in pairs offset one behind the other, wherein a pair of Verstellgerüsten 17 'forms a bending station of the forming unit 9.
- the adjusting scaffolds 17 and 1 T can be operated to produce profiles with variable height and constant width or profiles with variable height and variable 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.
- 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 present invention, the adjustment of the inclination of the plate holding the guides 23 is made either in exact agreement with the angle of inclination of the edge to be bent, or by correcting the inclination of this plate in consideration of the centric elongation as explained below in connection with Figs.
- 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 Blechbandreacardi) changed. At the same time, the variable depth is produced by this movement of the roller pairs 22.
- the adjustment framework 1 T By means of the adjustment framework 1 T 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 be realized by the operation of a lever by a linear drive, not shown, analogous to the above-mentioned DE 100 11 755 Al and will therefore not be explained here.
- 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.
- 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.
- the device according to the invention can be operated with or without a lowering / lifting unit 8.
- FIGS. 9A to 9D The profile of the profile flowers in the above operating mode is illustrated in FIGS. 9A to 9D, the solid line showing the normal cross section and the broken line the height-changed cross section.
- FIG. 9A shows the superimposition of the cross sections in the final shape of the profile
- FIG. 9B shows the profile flower of the normal cross section
- FIG. 9C shows the profile flower of the height changed cross section
- FIG. 9D shows the superimposition of the profile flowers of FIG 9B and 9C.
- roller pairs 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.
- the adjusting frames 17 and 1 T 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 sheet metal strip feeding plane X, Y and in particular parallel to the Y direction.
- Fig. 7C illustrates a variant of the Verstellgerüstes of FIG. 7 A, wherein like parts are identified by the same reference numerals. Contrary to the adjusting frame 17 of Fig. 7A, the adjusting frame 17 "of Fig. 7C has the mechanism 24 of the adjusting frame 1 T, whereby the angle of the base plate 20 in an oblique direction to the XY plane is adjustable Adjustability of the base plate 20 is no longer easily rotatable about shafts, and therefore their motorization is integrated into the roller stand (roll stand) 19, as indicated by reference numeral 18 ".
- a suitable motorization can readily be implemented by a person skilled in the art, for example in the form of a servomotor, an asynchronous motor, a motor with frequency converter or the like, and therefore needs no further explanation.
- the roller pair 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.
- 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.
- FIG. 7D illustrates a variant of the adjusting frame of FIG. 7B, wherein like parts are identified by the same reference numerals.
- the Verstellgerüst 17 '"of FIG. 7D has a suitable motor 18'', the 7C is integrated into the roller stand 19.
- the position of the base plate 20 along the circular arc 25 can be adjusted without any restrictions, so that analogously to the embodiment of the adjusting frameworks of FIG It is also possible to displace the roller pair 22 from a position in which its axes are parallel to the sheet metal belt conveyance plane X, Y to a position in which its axes are perpendicular to the sheet belt conveyance plane X, Y. This results in a Mode of action which is analogous to that of the adjusting frame of FIG. 7C.
- Both the adjusting frameworks 17 "of FIG. 7C and the adjusting frameworks 17" 'of FIG. 7D can, as shown in FIG. 8, be arranged in pairs one behind the other.
- 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.
- FIG. 9E shows the superimposition of the cross-sections in the final shape of the profile
- FIG. 9F shows the profile flower of the normal cross-section
- FIG. 9G the profile flower of the height-changed cross-section
- FIG. 9H the superimposition of the profile flowers of FIG. 9F and FIG 9G.
- FIGS. 9G and 9H thanks to the correction dependent on the centric extension, the bottom of the profile is lowered or raised in approximately equal steps.
- FIGS. 91 to 9L correspond to FIGS. 9E to 9H except 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 correction dependent on the centric extension leads.
- rollers of a roller stand are in their simplest form cylindrical and axis parallel, as shown in the above-mentioned DE 100 11 755 Al, 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.
- rollers of a roller stand need not be cylindrical, but they may have variable in diameter over their length, as shown in Figures 5, 7 and 8, to provide the sheet metal strip partially with a certain profile.
- 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.
- 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.
- Figures 1 IA to 1 ID show some of many possibilities for the construction and arrangement of two rollers of a roller stand.
- Fig. IA shows a classical, ie axis-parallel arrangement of the rollers with complementary variable diameters, which pass through a metal strip between them;
- Fig. IB shows an arrangement in which the axis of one roll is parallel to the sheet metal sheet feeding plane and the axis of the other roll is inclined thereto.
- Fig. 1C shows an arrangement in which the axes of the rolls are inclined not only to each other but to each other are offset from each other in the Blechbandf ⁇ rderides; and Fig.
- FIGS. 1B to 1 ID shows an arrangement in which the axes of the rollers inclined to each other, offset from each other in the Blechbandörderides and additionally rotated about the vertical axis (a more or less radially through both rollers line) against each other.
