- the profile material used should be optimally used with losses as low as possible.
- An essential feature is that a method and a device is used, which is the process for producing the bar profile and the process for bending the manufactured bar profile in a single Combined roll-form-bending machine (RFB).
- RFB Combined roll-form-bending machine
- the finished bent parts thus produced are then also preferred continuously forwarded via an automatic handling system.
- a bridge construction for receiving is connected upstream of the roll bending head a movable mandrel station. This can span the entire length of the bridge operated by motor (CNC controlled) or manually.
- the mandrel station has the task of using a mandrel bar, the mandrel shaft tool, which is positioned in the roll bending head, exactly on the bending line hold.
- the flat top of the bridge with various fastening options takes the roll stations necessary for profile production with drive, welding and grinding device, mandrel bar guides etc. on. Close separately Strip end welding machine and double reel for the coil.
- the Downstream of the roll bending head is a flying separation system.
- the bridge length depends on the number of profiles used for the manufacture of the profile necessary roller stations, with or without welding, grinding stations. etc. It can in a RFB system according to the invention, the most varied profiles Shape and size are made.
- the so-called forming flower one The resulting profile determines the location of the mandrel station.
- At a closed profile is positioned at the place where the Umformblume just as much opening of the two sheet ends of the Sheet metal strip width allows the mandrel rod holder to be in with the mandrel rod just fits into the closing gap cavity.
- Profile shape and profile type closed, partially open, open
- mandrel rod length Different.
- mandrel shank tool and thus the die are generally not required Mandrel bar.
- partially open or closed profiles are in any case Mandrel shank tools necessary.
- Thin-walled sheet metal profiles can usually be used with conventional ones Bending methods are very difficult and mostly do not bend at all.
- Profile roll bending is ideal for the free-form bending of rolled Suitable for sheet metal profiles.
- the combination of rolled profile production from the coil and profile rolling bending enables continuous production for the first time curved thin to thin-walled sheet metal profiles in 2 and 3 dimensions Execution.

- the Bending head 14 Downstream behind the last roll of the rear roll stations 7b is the Bending head 14 arranged, which is a second main component of the device for producing bending profiles according to the invention is assigned, namely the bending device 18. In the bending head 14, however, the finished still occurs unbent profile 13 from the profile forming station 6. Through 2- or 3-dimensional Bending in the bending head 14, the unbent profile 13 in the bent bending profile 15 deformed, which then by the cutting device 16 the desired length is cut off.
- the cutting device 16 can for example a flying saw, or a pair of scissors or one Cutting torch station or laser cutting station or the like.
- the separating member 17 of the cutting device 16 is the curved profile 15 can adapt so that the separating member 17 must be movable, 2 or 3 dimensions.
- the bending device 18 also includes the mandrel station 19, which is in the direction of displacement 20 is displaceably arranged on the bridge 21, on which bridge 21 the Entire profile forming station 6 is stored.
- the longitudinal displaceability of the Mandrel station 19 is only provided and made possible outside of the profile production a simple and quick adaptation of the system to another profile.
- the mandrel station 19 has the task of the mandrel rod on the, the mandrel shaft (for the Bend) on the opposite side.
- the mandrel station 19 is located So at a point shortly before the profile is closed or before completion of the profile.
- a thorn shaft is only used for closed and partially closed Profiles required, but can be omitted or removed for open profiles.
- FIG. 2 now shows an enlarged detailed illustration of the mandrel rod holder 19 with mandrel rod 22, downstream for further support of the mandrel rod 22, one or more mandrel bar guides 23 can be provided.
- This Mandrel bar guides 23 include at least two opposing ones idler rollers 24, 25, the sheet 3 to be deformed between them take up.
- One roller 24 is fixed on the mandrel rod 22 or arranged longitudinally displaceable, the other roll fixed or longitudinally displaceable the bridge 21 arranged.
- Figure 3 shows the deformation of the sheet 3 to the profile 13 over numerous Intermediate stages when passing through the roller stations 7 looking in Conveying direction 4 of the material 3, 13. It can also be seen that the outer roller 25 is wider than the inner roller 24 of the mandrel bar guide 23.
