Definitions

  • the invention relates to a device for forming curved components, in particular glued laminated beams, curved beams or the like, according to the preamble of patent claim 1.
  • a bending device of the type mentioned comprises a rigid part for generating the bending shape of the part to be bent, which is preferably cylindrical or at least has a curved surface on the opposite sides.
  • the counterpart to this is a slide-shaped, complementary component, the actual bending shape of the part to be bent being determined by the space between the fixed and the movable molded part of the bending device.
  • These separate shaped and counter-shaped parts of the bending device not only have to be manufactured separately, but they also have to be adjusted to the desired positions in the bending process to be carried out in each case. This adjustment work is time-consuming, and for the production of the shaped and counter-shaped parts which determine the bending shape, a considerable amount of material and time is additionally required.
  • angle brackets which are anchored in a concrete bed, are arranged in such a way that, for example, they have an arrangement comprises a plurality of angular brackets which are arranged in the manner of a template which is curved in accordance with the component to be produced. Aligning and arranging the angle brackets to form such a template is time-consuming and the work required for this must be carried out by hand.
  • the invention has for its object to provide a device for molding curved components of the generic type, which allows a simplified production of curved components with a selectable curvature and any length.
  • this object is achieved in a device for shaping curved components, in particular glulam beams, curved beams or the like, which has the features of the preamble of patent claim 1, in conjunction with the features of its characteristics.

  • the carriages of the clamping devices which serve as the base body can be moved to the desired locations while achieving the respectively desired arc shape of the component to be produced and the rotary tables mounted thereon with the at least two adjustable clamping elements, when the component is inserted and bent, are automatically aligned in the required angular position, the clamping elements being able to be opened and closed at any position of the slide, so that, if necessary can exert different pressing pressures on the component to be manufactured.
  • This device allows the production of components with any curvature in an almost universal manner, without time-consuming and complicated alignment work for the respective clamping devices.
  • the number of clamping devices used in the device for shaping curved components according to the invention can also be adapted to the desired application and, thanks to the modular design, can be expanded almost freely. This also ensures that the lengths of the curved components to be produced can be freely selected.
  • the device according to the invention is not only in the field of the production of glued wood and, for example, for the shaping of glulam beams in the production of components for residential building, such as door frames, lintels, dormer windows, rafters, etc., of formwork for concrete workers, of components for conservatories, pavilions, Pergolas, car parking spaces, playgrounds, etc. are particularly suitable, but with this device it is also possible to achieve shapes with other materials with similar elasticity modules, as is the case, for example, when creating welded structures from steel components.
  • the guides for the movable carriages are preferably arranged parallel to one another, and they are expediently provided in this arrangement on a base frame, so that the clamping devices can be moved independently of one another into the respectively desired position.
  • the device comprises a common drive device for moving the slides of the tensioning devices, for which purpose motors, chain drives and the like can be provided on the base frame of the device, for example, so that the work for the respective positioning of the slides of the tensioning devices can also be carried out easily and quickly Let untrained and inexperienced personnel do it.

  • Slideways or roller guides or combinations thereof can be used to guide the slide of each tensioning device, the respective type of guidance naturally also being dependent on the required manufacturing accuracy of the components to be manufactured and their size and / or length. It has proven particularly preferred to make the carriages of the tensioning devices movable on rollers along the guides, which are expediently designed as rail guides.
  • the tensioning elements of the respective tensioning device which are adjustable symmetrically to the axis of rotation, are preferably formed by tensioning rollers, so that when the component to be manufactured is deformed, when the paralleling tensioning devices are moved, the component can roll on these tensioning rollers and a line contact of the tensioning devices and the one to be manufactured Part has to avoid any visible bending marks on the surface of the part to be manufactured.
  • the adjusting device for the tensioning elements can also be driven by means of an electric, hydraulic, pneumatic drive
  • the required clamping forces can be varied and coordinated in an individual manner.
  • a basic embodiment of a device according to the The invention comprises, for example, seven adjustable clamping devices of the type mentioned above, and the most common lengths of the components to be bent can be processed with such a device.

In this way, on-line operation is possible, for example with a central computer for design and manufacture.
  • information and data such as CAD data
  • the device has a modular structure, so that one can achieve almost universal flexibility for shaping the most varied configurations of the components.
  • the tensioning devices can be moved independently of one another. Depending on the particular application, however, the tensioning devices can also be moved in a predetermined sequence and coupled to one another if necessary.
  • the tensioning devices are preferably arranged in a common plane, which is formed by the guides provided in parallel for moving the carriage of the tensioning device.

  • the respective rotary tables 9 automatically align themselves with the component to be bent, such as the beam 14, with regard to the angular position.
  • the carriage 6 can be locked in the intended end position on the guides 3 and fixed immovably.
  • the centrally arranged adjusting device 11 which can be formed, for example, by a chain sprocket 15
