Definitions
- the invention relates to a profiling station, a profiling unit formed from two associated professional profiling stations as well as a profiling system comprising a plurality of profiling stations and / or profiling units arranged one behind the other in the direction of flow for the continuous forming of a strip of material into a profile, in particular to a longitudinally welded profile with a rectangular cross section.
- EP 1 914 020 B1 describes a profiling frame of a generic type for a roll forming system with a first forming roll and a second forming roll, between which a material strip or profile to be formed is passed.
- a free-running side roller interacts with the two form rollers located on both sides of the material strip.
- a third form roller is provided, which is arranged opposite the second form roller.
- the central first form roller forms a first pair of form rollers with the second form roller and a second pair of form rollers with the third form roller.
- a second free-running side roller interacts with the second pair of form rollers.
- the profiling frame also includes a frame in which drive shafts are mounted for the form rollers.
- the profiling stand here is designed as a sloping roller unit, i. H. the second and third form rollers have axes of rotation that are angled with respect to the axes of the associated drive shafts.
- the disadvantage here is that the drive speeds and the associated peripheral speeds of the driven form rollers were difficult to match and the associated surface damage has occurred.
- a device for the continuous rolling of a sheet metal strip into a profile with profile legs that are straight in cross section has become known.
- the Vorrich device is used in particular for producing catch welded rectangular tubes.
- Frames with form rollers and counter rollers are arranged on supports so that the sheet metal strip to be deformed with the form and counter rollers of the frames on one side of a middle plane and with the form and counter rollers of the frames on the other side of the middle plane gradually edging the desired profile.
- the Schmidtrol len located below the sheet metal strip each have a cylindrical section and a truncated cone-shaped section adjoining it in the axial direction.
- the form rollers are freely rotatably mounted in the respective frames, the counter rollers being driven by a motor. What is disadvantageous here is that the frustoconical section along its surface line with the diameter to be taken also has an increasing peripheral speed. 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 a plurality of 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 to provide, by means of which a user is able to carry out reliable 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 behind one another and a profiling system with a plurality of profiling stations arranged directly one behind the other or a plurality of profiling units arranged directly behind one another in accordance with the claims.
- the profiling station is used for the continuous, permanent forming of a strip of material into a profile, in particular a longitudinally welded profile with a polygonal cross section or an open cross section.
- the material strip has a first flat side and a second flat side arranged opposite the first flat side.
- the profiling station defines and encompasses a longitudinal axis in the direction of travel of the material strip
- At least one form roller which at least one form roller can be turned towards the first flat side of the material strip
- first counter roller which first counter roller is cylindrical and defines a first roller axis and a first roller diameter
- a second counter roller which second counter roller is cylindrical, defines a second roller axis and a second roller diameter
- first counter roller and the second counter roller bil a counter roller pair and the counter roller pair of the second flat side of the material strip is applicable, and wherein the first roller axis and the second roller axis include a kink angle between them, and
- the counter-rollers of the pair of counter-rollers define between them a bending edge for the material strip to be formed
- a drive unit with at least one drive unit, at least one of the counter rollers of the pair of counter rollers being connected to the at least one drive unit in a drive connection,
- profiling arrangement and optionally the drive unit are held on the frame, and thereby
- the first counter roller and also the second counter roller are driven by the drive unit in such a way that the first counter roller on their outer circumference and the second counter roller on their outer circumference have an identical circumferential speed.
- the advantage achieved thereby is that by simultaneously driving both counter rollers for the material strip or sheet metal strip to be formed, safe and, above all, low-slip further transport through the individual profiling stations of the profiling system is achieved.
- the two counter rollers each have a cylindrical outer shape, to which the flat side of the material strip to be formed is located, there is no unwanted relative movement between the material strip and the counter rollers aligned at an angle to each other by the choice of the same peripheral speed.
- the strip of material to be formed is pressed by the form roller into the bending edge defined by the counter rollers of the counter roller pair and is thus pressed against the counter rollers which are aligned at an angle to one another.
- the form roller is preferably aligned in the bisector between the first roller axis and the second roller axis of the two counter rollers, whereby the pressure force is also divided into two force components. Since both counter rollers are now driven at their outer circumference at the same peripheral speed, this makes an effective forming process and gentle further transport of the material strip to be formed achieved in each of the profiling stations arranged one behind the other. This avoids surface damage to the flat side of the material strip due to different circumferential speeds of the counter rollers.
- first roller diameter of the first counter roller and the second roller diameter of the second counter roller are of the same size. If the two roller diameters of the counter rollers are chosen to be the same size, they can be driven at the same drive speed. This creates the possibility of providing a mechanical, non-positive transmission device between the two counter rollers in order to be able to transmit the drive torque from the driven counter roller to the other counter roller safely.
- a mechanical rotation transmission device is provided between the first counter roller and the second counter roller and that counter roller, which is connected to the first drive unit in drive, by means of the mechanical rotation transmission device, the drive torque to the other counter role transfers.

- the mechanical rotation transmission device comprises an articulated shaft.
- the mechanical rotation transmission device comprises an angular gear. If an angular gear is used between the two opposing counter rollers, a safe, mechanical transmission of the drive torque can also be achieved.
- the angular gear can in particular be used if the two roller axes enclose each other at approximately a right angle.
- a translation or reduction of the drive speed can also take place within certain limits, which also enables the use of different roller diameters.

- Another alternative embodiment is characterized in that the first roller axis and second roller axis of the counter rollers of a pair of counter rollers are arranged in a common plane, and the common plane is arranged in a normal orientation with respect to the longitudinal axis. This allows an even better alignment with respect to the bending edge defined by the cooperating counter rollers.
- Another 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 pair of counter rollers is arranged in a second plane and that the two planes are arranged parallel and offset from one another. From this training an even more individual adaptation to different forming conditions can be achieved.
- the invention also includes a profiling unit for continuous, remain the forming of a strip of material into a profile, in which two immediately after the arranged, according to the invention designed profiling stations are provided. This allows a symmetrical forming of the parts or partial sections of the material strip to be formed, which are located on both sides of the central plane. Furthermore, it can also be used 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.
- the profiling stations arranged directly one behind the other are arranged opposite one another and offset with respect to one another with respect to a central plane running in parallel direction with respect to the longitudinal axis.
- a shaping step can be carried out in each of them by the arrangement of the profiling stations opposite.
- the additional arrangement offset in the direction of the longitudinal axis enables an even more flexible use of the profiling system with the different widths of the material strip.
- profiling stations arranged directly one behind the other are arranged in mirror image with respect to one another with respect to a central plane running in parallel direction with respect to the longitudinal axis. Due to the mirror image arrangement, a symmetrical deformation process can be achieved with each of the profiling units.
- a further preferred embodiment is characterized in that the profiling stations arranged directly one behind the other are guided in an adjustable manner on the base frame in the normal direction with respect to the longitudinal axis, in particular in the normal direction with respect to the central plane. This allows the required processing width to be adjusted to the respective width of the material strip.
- the invention also includes a profiling system for continuous, remain the forming of a strip of material into a profile, in which several in the direction of a longitudinal axis directly behind one another, designed according to the invention profiling stations are provided.

- the two partial longitudinal strips 34, 35 form together one of the partial flat sides of the profile to be produced. Due to the mutually different widths of the two partial longitudinal strips 34, 35, the butt joint and the closing connecting region formed at closing are not arranged symmetrically with respect to the central plane 4. So that the butt joint and the subsequently formed longitudinal connection area is offset by an offset 36 and thus laterally offset be arranged with respect to the central plane 4.
