Definitions

  • the invention relates to a device and a method for the flexible roll forming of a semi-finished product, in particular a rolled sheet, into a profile with a cross section varying along its longitudinal axis and / or with a varying longitudinal axis.
  • the transport and profiling of a rolled sheet is carried out in a manner known per se by driven profiling rolls.
  • the profiling rollers which are spatially very close to one another, transmit the forming forces required for shaping and transport to the rolled sheet by friction.
  • the rolled sheet is conveyed through a roll gap formed between the profiling rollers, in which the forming forces required for the shaping are transmitted to the rolled sheet.
  • DE 100 1 1 755 A1 discloses a device for roll profiling longitudinally oriented components, which has a frame with a plurality of support devices which are carried by the frame. Each support device is designed as a slide and can be moved in translation relative to the frame by means of threaded spindles.
  • a profiling unit referred to as the scaffold half, is arranged on each support device, each of which has a pair of rotatably mounted rollers, between which a roll gap remains.
  • EP 1 676 654 A1 discloses a roll forming system in which a plurality of support devices referred to as forming station supports each carry three profiling units.
  • support devices with the profiling units carried by them are each translationally movable and rotatable about a vertical axis of rotation.
  • the arrangement of three profiling units on one supporting device each makes the system more stable overall than the device described in DE 100 1 1 755 A1.
  • a disadvantage of this known roll forming system is that only relatively large Krümmungsra dien the profile outer edges can be achieved in the profiling plane containing the longitudinal direction. This also applies if the profiling units are individually adjustable, as is proposed in EP 1 676 654 A1, since even then three profiling units are always secured together on a support device.
  • EP 2 134 484 B1 disclose roll profiling systems, each of which has profiling units which can be rotated independently of one another and are each individually attached to a separate stand part.
  • the SE 135 00 12 AI describes a roll forming system with pairs of profiling units.
  • Two profiling units are directly connected to each other and can be moved relative to each other perpendicular to the direction of conveying.
  • the two profiling units can be rotated together about a central axis of rotation which is arranged between the profiling units.
  • the object of the invention is therefore to provide a device and a method for flexible roll forming of a semifinished product which meets the above-mentioned disadvantages from the prior art and enables the production of free-form profiles with very small radii of curvature in a low-vibration operation.
  • a device for flexible roll forming of a semi-finished product, in particular a rolled sheet, of the type mentioned at the outset which has a frame.
  • a plurality of support devices are carried by the frame, the support devices being each mounted so as to be translatable and rotatable relative to the frame.
  • the device also has a plurality of profiling units, each one Have a pair of rotatably mounted rollers, between which a roll gap remains, which is dimensioned such that a semi-finished product, in particular a rolled sheet, can be conveyed along a conveying direction by frictional engagement of the rollers and at the same time can be roll formed.
  • the device according to the invention has the advantage that two profiling units are connected to one another via a support device and thereby form a rigid compound in spite of the individual rotatability of the profiling units.
  • the support device which carries two profiling units in comparison to the known device and therefore inevitably has a larger extension, can in turn be supported on opposite ends on the frame, which reduces the risk of tilting vibrations due to the deformation forces.
  • the device according to the invention as a whole has a stiffer structure which enables low-vibration operation.
  • the device according to the invention thus represents an optimal compromise as to the achievable radii of curvature for the profile outer edges on the one hand and a low-vibration structure on the other hand.
  • the support devices and the profiling units mounted on them are preferably arranged in two rows running essentially parallel to one another and essentially parallel to a profiling plane when the device is at rest.
  • the two rows of support devices can diverge, converge or be arranged irregularly in the conveying direction. It is also possible to arrange the support devices offset from one another at a height level in the conveying direction.
  • the profiling plane is defined by the orientation of the semi-finished product just entering the device. While the longitudinal axis and the cross section of a semi-finished product to be rolled can change over the conveying and forming time, the profiling plane defined once when the semi-finished product enters the device remains the same even when the height level of the support devices changes.
  • the support devices and the profiling units carried by them have several independent translatory and rotary elements Have degrees of freedom.
  • Independent degrees of freedom are understood to mean axes of rotation and translation, around or along which at least one element of the support devices, the profiling units or the frame can be rotated or moved in translation.
  • at least one support device is rotatably mounted about a first axis of rotation, which is arranged parallel to a first direction of rotation.
  • At least one Profileierein unit is rotatably mounted about a second axis of rotation, which is arranged parallel to a second direction of rotation.
  • the support device is translationally movable parallel to a translation direction, the first direction of rotation including a first angle with the translation direction, which is preferably 90 °, and the second direction of rotation with the translation direction includes a second angle.
  • the second axis of rotation runs through a processing point in the roll gap between the pair of rotatably mounted rollers of the at least one profiling unit. Due to this position of the second axis of rotation, the pair of rollers of each profiling unit can be aligned so that the machining point is optimally positioned to the outer profile edge of the semi-finished product to be rolled. This in turn enables particularly precise machining accuracy.
  • the pairs of rotatably mounted rollers each comprise a first roller and a second roller different from the first roller, the first and second rollers each having at least one circumferential circumferential first order shaped section and an offset in the axial direction and circumferentially have direction circumferential second forming section.
  • the processing point is then located at the transition from the first forming section to the second forming section.
  • the transition can itself be designed as a conical third forming section, for example.
  • first and second axes of rotation each run essentially parallel to one another and the direction of rotation of the axes of rotation is essentially orthogonal to the translation direction of the translation axes.
  • first and second axes of rotation and the translation axes are oriented completely differently and thus there are several directions of rotation and several directions of translation for the support devices and the profiling units.
  • the asymmetrical rotation and travel behavior and / or the skewed rotation and translation axes of the support devices and profiling units can be compensated for, for example, by inclined components of the frame and / or varying basic geometrical shapes of the support devices and / or a further axis of rotation.
  • Such a further axis of rotation can be, for example, a horizontal axis of rotation for inclining the profiling units toward the semi-finished product to be profiled or away from the semi-finished product to be profiled. Compensation is understood here to mean that the same profile shapes can be achieved.
  • first and second axes of rotation are each arranged eccentrically to the respective geometric center axis, since on the one hand the support devices can thus pivot out further and on the other hand the angular positions of the profiling units can be adjusted more precisely to the moving profile outer edge of the semi-finished product.
  • the eccentricity is preferably so great that if the supporting devices each have an elongated basic shape with at least two shorter opposite sides, the first axis of rotation runs through a point of the supporting devices, the distance to one of the two shorter sides of which is at least twice as large as to the other side.
  • the profiling units each have an elongated basic shape with at least two shorter opposite sides, the second axis of rotation runs through a point of the profiling units, the distance from one of the two shorter sides is at least twice as large as that at each whose side.
  • the ratio of the distances from the axes of rotation to the respective sides is preferably in a range from 2: 1 to 25: 1, but particularly preferably in a range from 5: 1 to 15 :1.
  • the supporting devices are in one embodiment, for example, supporting at least two supporting device bearing points stored.
  • the support devices can also have three support devices instead of two.
  • the support devices can each have two first support elements, the two first support elements providing a first support device mounting point and a second support device mounting point.
  • the support devices each have a first rotary element which defines the first axis of rotation and provides a third support device for the mounting point.
  • the profiling units have three instead of two profiling unit bearing points.
  • the profiling units can each have two second support elements, the two second support elements providing a first profile cleanliness bearing point and a second profiling unit bearing point.
  • Each profiling unit has a second rotating element that defines the second axis of rotation and provides a third profiling unit bearing point.
  • the second rotary drives can each have a first transmission element, e.g. a curved rack that is in engagement with a second transmission element, in particular a gear.
  • the two transmission elements can be arranged at a greater distance from the second axis of rotation.
  • the semi-finished products to be rolled in the plant, in particular rolled sheets, can preferably have ductile materials such as aluminum (Al), manganese (Mn), zinc (Zn), titanium (Ti), iron (Fe) or alloys of these materials.
  • the roll-feed semifinished products particularly preferably have aluminum (Al) and aluminum alloys. Elemental aluminum as well as aluminum alloys with a high aluminum content (for example over 75 atomic%) have the special property of a passivating protective layer made of aluminum oxide that is impermeable to air, water and a broad spectrum of light (AIO) or boehmite (AIO (OH)). This passivating protective layer protects the underlying aluminum or the underlying aluminum alloy from corrosion. As this is a natural process, these materials are particularly suitable for further processing into profiles that will later be used outdoors.
