Definitions

  • 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.
  • 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.
  • the U-profiles shown therein have a constant width.
  • the V-profile of Fig. 4C has a variable height and a variable width 33.
  • 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.
  • 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.
  • FIG. 5 Now is a perspective view of a Inventive device for cold rolling profiling of profiles with variable height described.
  • 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.
  • 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, Schnellstanz wisdom, 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.

  • 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.
  • 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.
  • 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.

  • 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 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.
  • the axis of rotation of the roller stand 19 axis parallel between two rollers 22
  • the inventive arrangement described, the translational degree of freedom and the rotational degree of freedom are decoupled from each other.
  • 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.
  • 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.

  • COPRA Adaptive Motion control from the home of the applicant done.
  • 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.
  • 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 stands 17 and 17 ' can be operated to produce profiles of variable height and constant width or profiles of 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 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.
  • 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 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.
