  • NC program a control program for a bending device in which the springback when twisting the profile to be deformed is to be counteracted.
  • a control signal is formed from the difference between the theoretically calculated relative rotation and the actual relative rotation. The profile is then twisted until the permanent torsion corresponds to the desired value, even after springing back the profile.
  • the object of the present invention is to provide a method and a device in order to be able to bend any rod-shaped components in two or three dimensions without springback. It should be bent in two or three dimensions in addition to cross-sectionally circular tubes and any profile cross-sections. The total length of the tubes and profiles should not be limited by the structure of the device according to the invention.
  • dumbbells For bending pipes, mainly dumbbells are used today ( Franz, W.-D .: wortlles Rohrbiegen. Procedures and machines. VDI publishing house, ISBN 3-18-400814-2, 1988 ).
  • 3D bending the pipe to be bent is rotated by rotating the tube cross-section and brought into another bending plane in these machines, in which then bent further. This change in the bending planes produces corresponding 3D contours.
  • only fixed, predetermined by the bending tools radii are possible.
  • the generation of 3D bends in profiles on such machines is impossible because changing the bending plane in a profile, unlike tubes with a circular cross-section, the required tool cross-section changes.
  • any rod-shaped components can be bent in two or three dimensions.
  • any desired profiles can be bent two- or three-dimensionally, with the total length of the tubes or profiles not being limited by the construction of the device according to the invention.

  • a plastic deformation in the roller system A is thus reliably avoided and the deformation in the area of the forming zone always achieves the same result.
  • a bent components can be provided with a constant production speed.
  • This production can be integrated particularly advantageous in clocked, continuous production processes.
  • the roller drive system components of any length can be presented at a constant speed.

  • the entire roller system B is disposed on an independent support system and movable relative to the roller system A in at least a first plane.
  • the bend of the tube or profile is made by changing the relative position of the roller systems A and B to each other while the tube or profile is being transported by the roller systems.
  • a transverse force is preferably distributed uniformly over the component cross section.
  • a tangential support of the roller system B is guaranteed on the component. Rollers with a larger contact surface are tracked during bending in tangential alignment of the support surface to the component surface. Tilting of the component between the roller systems A and B is thus safely avoided.
  • the roller systems enclosing the rod-shaped component have adjusting mechanisms.
  • the roll systems can be be adjusted by each adjustable in their distance from the longitudinal axis rollers on components with asymmetrically profiled sections having different cross-sections.
  • Such structured sections can be bent in sections, adjusting the roller systems to the changed component cross-section directly, without lengthy replacement of roles.
  • the contact pressure of the rollers can be adjusted to ensure a frictional transport in the roller system A.
  • the rollers of the roller system B are thereby preferably set to a low coefficient of friction, which additionally favors the sliding of the component along the preferably tangentially guided bearing surfaces of the rollers.
  • the rollers of the roller system B are likewise drivable.
  • the drive of the component takes place at an angle ⁇ to the longitudinal axis of the rod-shaped component.
  • About frictional contact in the roller bearing surfaces can be superimposed by increased or reduced propulsion of the roller system B in the forming zone between the roller systems an additional tensile or compressive stress.
  • the roller system B in a further plane, which is aligned at right angles to the first plane E1, by a rotational angle ⁇ rotatable.

  • the rotational angle ⁇ is varied in the process of the roller system so that the bearing surfaces of the rollers are guided tangentially to the component surface.
  • the roller systems A and B are each rotatable about the profile longitudinal axis by appropriate rotary mechanisms.
  • the bending plane can be rotated about the profile longitudinal axis, whereby a third plane can be influenced and 3D-curved components can be produced.
  • the first axis moves the roller system at the exit of the machines and thus generates the bending of the profile. Due to the rotation of the roller systems A and B, the second axis makes it possible to change the bending planes and thus the bending of 3D contours.
  • a torsional moment is introduced into the bending zone between the roller system A and the roller system B.
  • the axis of rotation of the machine is set around the profile longitudinal axis at different angles in the outlet roller system and in the other roller systems. This can be done, as with all moving axes of the machine, by manual or NC control of the drive axles, which may be electrical or hydraulic.
  • a mandrel system is mounted, which comprises a mandrel, e.g. holds in a limb-dome-like design, in the forming zone of the process and so the occurrence of cross-sectional deformations z. B. may occur in hollow sections, reduced.
  • Fig. 1 one sees an exemplary embodiment of the invention.
  • two profiled roller pairs 1 have been arranged one behind the other for the axial drive of the profile 2.
  • These pairs of rollers are arranged on a housing 4, in which the corresponding drive of all roles and a mechanism for adjusting and pressing the pairs of rollers are integrated.
  • the ring 5 and the shaft socket 6 are mounted, which allow in the bearing housings 7 and 8, a rotation of the entire housing.

  • a hydraulic cylinder 9 which allows in this case a rotation of 90 degrees in total; but here is also a rotary drive (electrical or hydraulic type), which would enable a full 360 degrees.
  • the roller system 3 which is located at the outlet of the machine is executed like a die and encloses the profile cross-section of four sides by means of bending rollers 3a, b, c, d. It can also be adjusted radially when changing the profile type to the corresponding profile cross-section.
  • This system is also able in this embodiment to carry out the rotation about the longitudinal axis of the profile to be bent, and is also driven. This allows in this embodiment, in addition to changing the bending plane, the introduction of a torsional moment in the process with the advantages mentioned above.
  • An additional axis of rotation perpendicular to the profile longitudinal axis is required to ensure the tangency of the roller assembly with changing bending radii.
  • the formation of the bending radii is achieved by the method of the carriage 10 on the linear axis 11, which generates the bending radius by its relative position.

This is done advantageously in that in the pairs of rollers A and / or B sensors for measuring the forces and moments occurring during bending and twisting of the profile are arranged. From this and optionally in conjunction with the data determined by the aforementioned contour sensor, the profile-specific material data required for process simulation or improved process planning can be determined by means of conventional programs.

  • the cutting tool can not only be realized in the form of a shear cut, but also in the form of a cutting tool with rotating tool movement, with effect of several sides or by a cutting or thermal cutting process. It is advantageous that the orientation of the cutting tool is always carried tangentially to the profile contour. Also, the fixed installation at the end of the bending device makes sense, since it allows a flying cut during the process without consuming entraining devices.
