Definitions

  • the invention relates to a profiling station, a profiling unit formed from two associated profiling stations, and a profiling system comprising several profiling stations and/or profiling units arranged one behind the other in the direction of flow for the continuous forming of a material strip into a profile, in particular into a longitudinally welded profile with a rectangular cross-section.
  • the JP 2000 042640 A describes a forming unit for forming an elongated sheet metal part into a cross-sectional shape that is angled relative to it.
  • the two legs of the sheet metal part are pressed against another central roller with a double truncated cone shape by cylindrical rollers with rotation axes that are angled to each other.
  • both cylindrical rollers are driven separately from one another by a common drive shaft.
  • the central roller with the double truncated cone shape is also driven by the same drive motor via the common gear.
  • each of the rollers is driven by its own drive motor.
  • the roll-formed object has a dimension that varies in its width direction - namely in the direction of the height.
  • the dimension varies continuously in the longitudinal direction of the roll-formed component.
  • several individual rollers are provided next to one another and one above the other in the transverse direction with respect to the longitudinal extension of the object.
  • the US 4 558 577 A describes a technique of metal forming using a roll forming device designed to produce articles from a workpiece with longitudinally varying cross-sectional dimensions.
  • the roll forming machine comprises a series of roll forming stands for forming a flat workpiece into the desired cross-sectional configuration. Furthermore, a separate device for monitoring the positioning of the workpiece on the input side of the roll forming machine and a control unit for sending signals to each roll forming stand to effect the transverse movement of the forming elements according to a predetermined roll forming pattern.
  • the roll forming stand can have either driven contoured rollers or non-driven forming rollers.
  • the roll forming stands each have interacting pairs of rollers which are jointly adjustable in the transverse direction with respect to the longitudinal extent of the workpiece to be formed.
  • JP H04 59101 A a forming unit for forming an elongated sheet metal part to an angled cross-sectional shape.
  • the two legs of the sheet metal part are formed according to the Fig.6 by cylindrical rollers with rotation axes aligned at an angle to each other against another central roller with a double truncated cone shape. Because the two cylindrical rollers rest on one of the legs, they rotate at a circumferential speed that is the same as each other.
  • each pair of rollers comprises a first and a second forming roller rotatably mounted on corresponding roller bearings, wherein one of the first and second forming rollers is movable both upwards and downwards transversely to its axis of rotation and axially along its axis of rotation.
  • This achieves an adjustment of the roller distance between the first and the second forming roller in two planes.
  • the two adjustment movements can take place simultaneously, so that an adjustment in a diagonal direction between one of the forming rollers and the other is effected in each of the pairs of rollers.
  • the EP 1 914 020 B1 describes a generically designed profiling frame for a roller forming system with a first forming roller and a second forming roller, between which a material strip or profile to be formed is passed.
  • a free-running side roller works together with the two forming rollers located on either side of the material strip, which are mounted as free-running rollers on the profiling frame and are without any Drive connection with a drive.

  • the profiling frame in question here is designed as an inclined roller unit, i.e. the second and third forming rollers have axes of rotation that are angled relative to the axes of the associated drive shafts.
  • the disadvantage here is that the drive speeds and the associated peripheral speeds of the driven forming rollers were difficult to coordinate with one another and this resulted in surface damage.
  • a device for continuously rolling a sheet metal strip into a profile with profile legs that are straight in cross-section has become known.
  • the device is used in particular for producing longitudinally welded rectangular tubes.
  • Frames with forming rollers and counter rollers are arranged on supports in order to gradually bend the sheet metal strip to be formed into the desired profile using the forming and counter rollers of the frames on one side of a central plane and the forming and counter rollers of the frames on the other side of the central plane.
  • the counter rollers located below the sheet metal strip each have a cylindrical section and a frustoconical section adjoining it in the axial direction, both of which are arranged on a common shaft.
  • the forming rollers are freely rotatable in the respective frames, with the counter rollers being driven by a motor.
  • the disadvantage here is that the frustoconical section along its surface line also has an increasing peripheral speed as the diameter increases. This leads to surface damage to the sheet metal strip to be formed.
  • the object of the present invention was to overcome the disadvantages of the prior art and to provide a profiling station, a profiling unit formed from two associated profiling stations and a profiling system comprising several profiling stations or profiling units arranged one behind the other in the direction of flow for the continuous forming of a sheet metal strip into a profile, by means of which a user is able to carry out safe forming even with profiles with a high or large aspect ratio with a perfect surface quality in the forming area.
  • a profiling station a profiling unit comprising two profiling stations arranged directly one behind the other and a profiling system with several profiling stations arranged directly one behind the other or several profiling units arranged directly one behind the other according to the claims.
  • the advantage achieved by this is that the simultaneous drive of both counter rollers for the material strip or sheet metal strip to be formed results in safe and, above all, low-slip transport through the individual profiling stations of the profiling system. Because the two counter rollers each have a cylindrical outer shape, against which the flat side of the material strip to be formed rests, the selection of the same circumferential speed means that there is no unwanted relative movement between the material strip and the counter rollers, which are aligned at an angle to one another. The material strip to be formed is pressed by the forming roller into the bending edge defined by the counter rollers of the counter roller pair during the passage movement and is thus pressed against the counter rollers, which are aligned at an angle to one another.
  • the forming roller is preferably aligned in the bisector between the first roller axis and the second roller axis of the two counter rollers, which also increases the pressing force. into two force components. Since both counter rollers are now driven at the same circumferential speed on their outer circumference, an effective forming process and gentle further transport of the material strip to be formed in each of the profiling stations arranged one behind the other is achieved. This avoids surface damage to the flat side of the material strip due to different circumferential speeds of the counter rollers.
  • a mechanical rotation transmission device is provided between the first counter roller and the second counter roller.
  • the counter roller which is in drive connection with the first drive unit transmits the drive torque to the other counter roller by means of the mechanical rotation transmission device. This means that a precisely specified drive speed is mechanically transmitted from the driven counter roller to the other counter roller that interacts with it. This ensures low-slip to almost slip-free synchronization between the counter rollers that are in drive connection with one another.
  • the mechanical rotation transmission device includes a cardan joint.
  • the choice of the cardan joint makes it even easier to adjust the angular position of the two roller axes relative to each other.
  • the mechanical rotation transmission device comprises a cardan shaft. By choosing a cardan shaft as the mechanical rotation transmission device, additional length compensation and adaptation to different operating conditions can be easily achieved.
  • a further alternative embodiment of the mechanical rotation transmission device provides that the mechanical rotation transmission device comprises a bevel gear arrangement with a first bevel gear and a second bevel gear.
  • the mechanical rotation transmission device comprises an angular gear. If an angular gear is used between the two interacting counter rollers, this also achieves a secure, mechanical transmission of the drive torque.
  • the angular gear can be used in particular when the two roller axes form an approximately right angle to each other.
  • the drive speed can also be increased or reduced within certain limits, which also enables the use of different roller diameters.
  • first roller diameter of the first counter roller and the second roller diameter of the second counter roller are the same size. If the two roller diameters of the counter rollers are the same size, they can be driven at the same drive speed. This makes it possible to provide a mechanical force-locking transmission device between the two counter rollers in order to be able to safely transfer the drive torque from the driven counter roller to the other counter roller.
  • a further preferred embodiment is characterized in that the drive unit comprises a further drive unit and the at least one forming roller is in a drive connection with the further drive unit. This allows an additional driving force to be introduced onto the material strip to be formed. However, equal circumferential speeds with respect to the circumferential speeds of the counter rollers must also be ensured or taken into account.
  • a guide arrangement is provided, by means of which guide arrangement the at least one forming roller is adjustably guided on the frame This allows adaptation to different thicknesses or strengths of the material strip to be formed.
  • the gap width between the forming roller and the opposing counter rollers can be adjusted and set.
  • Another alternative embodiment is characterized in that the first roller axis and second roller axis of the counter rollers of a counter roller pair are arranged in a common plane, and the common plane is arranged in a normal alignment with respect to the longitudinal axis. This makes it possible to achieve an even better alignment with respect to the bending edge defined by the cooperating counter rollers.
  • a further preferred embodiment is characterized in that the first roller axis of the first counter roller is arranged in a first plane and the second roller axis of the second counter roller of a counter roller pair is arranged in a second plane and that the two planes are arranged parallel and offset from one another.
  • the invention also includes a profiling unit for the continuous, permanent forming of a material strip into a profile, in which two profiling stations designed according to the invention are provided, arranged directly one behind the other. This makes it possible to achieve symmetrical forming of the parts or sections of the material strip to be formed located on both sides of the center plane. Furthermore, this also makes it possible to create a modular system for forming the profiling system.
  • Another possible and possibly alternative embodiment has the features that a base frame is provided and the two profiling stations arranged directly one behind the other are arranged and held on the base frame.
  • profiling stations arranged directly one behind the other are arranged opposite one another and offset from one another with respect to a central plane running parallel to the longitudinal axis. This means that a forming step can be carried out in each of the profiling stations due to the opposing arrangement.
  • the additional offset arrangement in the direction of the longitudinal axis enables even more flexible use of the profiling system for a wide range of material strip widths.
  • profiling stations arranged directly one behind the other are arranged in a mirror image of each other with respect to a center plane running parallel to the longitudinal axis.
  • the mirror image arrangement enables a symmetrical deformation process to be achieved in each of the profiling units.
  • a further preferred embodiment is characterized in that the profiling stations arranged directly one behind the other are adjustable on the base frame in the normal direction with respect to the longitudinal axis, in particular in the normal direction with respect to the center plane. This allows the required processing width to be adjusted to the respective width of the material strip.
  • the invention further comprises a profiling system for the continuous, permanent forming of a material strip into a profile, in which a plurality of profiling stations designed according to the invention are provided, arranged directly one behind the other in the direction of a longitudinal axis.
  • the advantage achieved by this is that the multiple arrangement of several profiling stations one behind the other enables rapid and safe further transport of the material strip to be formed. In addition, a higher driving force is applied to the material strip for the forward movement.

It should be mentioned that cross-sections that are open over the circumference, such as L-profiles, U-profiles, C-profiles, Z-profiles or the like, can also be formed from the material strip 3 by forming.
  • the forming process is carried out by so-called roll forming, also known as roll forming or cold rolling of profiles.
  • roll forming an originally flat material strip 3, in particular a sheet metal strip, which can be made of a wide variety of materials, is usually passed through several modular rollers or rolls arranged one behind the other and working together, and is continuously formed until the final cross-sectional shape is achieved.

  • the connecting seam in the area of the longitudinal edges to be connected to form the closed profile has been omitted.
  • the center plane 4 is shown in the center of the profile.
  • the two partial longitudinal strips 34, 35 arranged along the edge of the material strip 3 in the longitudinal extension have a different width to one another in a cross-sectional plane that runs in a normal alignment with respect to the longitudinal axis 7.
  • the partial longitudinal strip 34 located on the left side of the center plane 4 at the beginning has the greater width than the partial longitudinal strip 35 located on the right side at the beginning of the forming process.
  • the two partial longitudinal strips 34, 35 together form one of the partial flat sides of the profile to be produced. Due to the different widths of the two partial longitudinal strips 34, 35, the butt joint and the longitudinal connection area formed afterwards are not arranged symmetrically with respect to the center plane 4. Thus, the butt joint and the subsequently formed longitudinal connection area are arranged off-center by an offset 36 and thus laterally offset with respect to the center plane 4.
