DESCRIZIONE dell'invenzione industriale dal titolo: "Procedimento per la curvatura di un elemento profilato metallico con contenimento delle deformazioni della sua sezione e relativa apparecchiatura" DESCRIPTION of the industrial invention entitled: "Procedure for bending a metal profiled element with containment of the deformations of its section and relative equipment"
DESCRIZIONE DESCRIPTION
La presente invenzione si riferisce ad un procedimento per la curvatura mono- o pluri-dimensionale di un elemento profilato metallico ed alla relativa apparecchiatura. The present invention refers to a process for the one- or multi-dimensional bending of a metal profiled element and to the relative apparatus.
Scopo della presente invenzione è quello di fornire un procedimento del tipo sopra indicato in cui l'effettuazione della curvatura, in particolare mediante stiramento, non provochi,.quale effetto collaterale, la deformazione della sezione trasversale dell'elemento profilato. The object of the present invention is to provide a process of the type indicated above in which the execution of the curvature, in particular by stretching, does not cause, as a side effect, the deformation of the cross section of the profiled element.
Tale scopo viene raggiunto grazie ad un procedimento di curvatura caratterizzato dal fatto che prevede di esercitare su detto elemento profilato una forza di contenimento in direzione sostanzialmente ortogonale a quella delle forze che provocano la curvatura, nello stesso tempo in cui vengono esercitate queste ultime. This object is achieved thanks to a bending process characterized in that it provides to exert on said profiled element a restraining force in a direction substantially orthogonal to that of the forces causing the bending, at the same time as the latter are exerted.
Tale forza di contenimento contrasta la tendenza a deformarsi della sezione trasversale dell'elemento, che può così mantenere la sua forma originale . This containment force counteracts the tendency to deform of the cross section of the element, which can thus maintain its original shape.
Gli elementi profilati sottoponibili al procedimento dell'invenzione sono ad esempio di tipo aperto o parzialmente chiuso. The profiled elements subject to the process of the invention are for example of the open or partially closed type.
Costituisce un ulteriore oggetto della presente invenzione un'apparecchiatura per l'effettuazione del procedimento sopra indicato, la quale comprende mezzi atti ad esercitare sull'elemento da curvare una forza di contenimento in direzione sostanzialmente ortogonale a quella delle forze che provocano la curvatura. A further object of the present invention is an apparatus for carrying out the above-indicated process, which comprises means capable of exerting a containment force on the element to be curved in a direction substantially orthogonal to that of the forces causing the curvature.
Ulteriori vantaggi e caratteristiche della presente invenzione risulteranno evidenti dalla descrizione dettagliata che segue, effettuata con riferimento ai disegni annessi forniti a titolo di esempio non limitativo, in cui: Further advantages and characteristics of the present invention will become evident from the detailed description which follows, made with reference to the attached drawings provided by way of non-limiting example, in which:
la figura 1 è una vista prospettica di un elemento profilato metallico da curvare mediante il procedimento dell'invenzione, e Figure 1 is a perspective view of a metal profiled element to be curved by the method of the invention, and
la figura 2 è una vista in sezione secondo la linea II-II di figura 1 di tale profilato collocato su di un'apparecchiatura che consente di realizzare il procedimento dell'invenzione. Figure 2 is a sectional view along the line II-II of Figure 1 of this profile placed on an apparatus which allows the process of the invention to be carried out.
Un elemento profilato metallico 10 di forma oblunga e presentante una sezione trasversale ad omega (figura 1) deve,essere curvato pluridimensionalmente, come indicato dalle frecce 14. A metal profiled element 10 having an oblong shape and having an omega cross section (Figure 1) must be multidimensionally curved, as indicated by the arrows 14.
Per realizzare questo procedimento di curvatura, si utilizza un'apparecchiatura comprendente, in modo di per sé noto ed illustrato solo schematicamente in figura 2, una sagoma 16 avente il profilo che si intende far assumere all'elemento ed una serie di punzoni 18 azionati da rispettivi martinetti 20 atti a schiacciare l'elemento 10 contro la sagoma 16. To carry out this bending process, an apparatus is used which comprises, in a manner known per se and illustrated only schematically in Figure 2, a shape 16 having the profile that the element is intended to assume and a series of punches 18 operated by respective jacks 20 adapted to press the element 10 against the shape 16.
Le superfici della sagoma 16 e dei punzoni 18 destinate ad andare in contatto con l'elemento 10 hanno un profilo che riproduce quello di quest'ultimo, così da fornirgli un adeguato sopporto durante la curvatura. The surfaces of the shape 16 and of the punches 18 intended to come into contact with the element 10 have a profile which reproduces that of the latter, so as to provide it with adequate support during bending.
L'apparecchiatura comprende inoltre mezzi atti ad esercitare sull'elemento 10 una forza di contenimento in direzione sostanzialmente ortogonale a quella delle forze che provocano la curvatura per stiramento . The apparatus also comprises means suitable for exerting a containment force on the element 10 in a direction substantially orthogonal to that of the forces which cause the bending by stretching.
Tali mezzi di contenimento sono realizzati nella forma di pinze 22 collocate in nicchie 24 ricavate lungo entrambi i lati della sagoma 16 ed aventi ganasce 26 suscettibili di afferrare i bordi trasversali di estremità dell'elemento 10. These containment means are made in the form of pincers 22 located in niches 24 formed along both sides of the shape 16 and having jaws 26 capable of gripping the transverse end edges of the element 10.
Le ganasce 26 delle pinze 22 sono azionate da rispettivi martinetti 28 ad azionamento meccanico, pneumatico, idraulico o elettrico. The jaws 26 of the grippers 22 are actuated by respective jacks 28 with mechanical, pneumatic, hydraulic or electric actuation.
In forme non illustrate di attuazione dell'invenzione, le pinze possono essere sostituite da morse ed essere azionate da leveraggi meccanici, anziché da martinetti. In embodiments of the invention not illustrated, the pliers can be replaced by clamps and operated by mechanical levers, rather than by jacks.
Per l'effettuazione del procedimento di curvatura, le ganasce 26 delle pinze 22 mantengono i bordi di estremità dell'elemento 10 aderenti alla sagoma 16, cosicché le forze esercitate dai punzoni 18 provocano la desiderata curvatura per stiramento dell'elemento 10 senza deformarne la sezione trasversale . To carry out the bending process, the jaws 26 of the pliers 22 keep the end edges of the element 10 adhering to the shape 16, so that the forces exerted by the punches 18 cause the desired bending by stretching the element 10 without deforming its section. transversal .
A seconda della forma dell'elemento 10 e delle forze di curvatura a cui viene sottoposto, è possibile prevedere uno specifico numero di pinze 22 e/o una loro particolare disposizione, in modo tale per cui, durante tutto il procedimento di curvatura, la sezione trasversale del profilato resti inalterata. Depending on the shape of the element 10 and the bending forces to which it is subjected, it is possible to provide a specific number of pincers 22 and / or a particular arrangement thereof, so that, during the entire bending process, the section transversal section remains unchanged.
Naturalmente, fermo restando il principio dell'invenzione, i particolari di realizzazione e le forme di attuazione potranno empiamente variare rispetto a quanto descritto a puro titolo esemplificativo, senza per questo uscire dal suo ambito. Naturally, the principle of the invention remaining the same, the details of construction and the forms of embodiment may impiously vary with respect to what has been described purely by way of example, without thereby departing from its scope.
Ad esempio, la curvatura dell'elemento profilato può avere luogo anche solo monodimensionalmente, con l'asse longitudinale dall'elemento che rimane nel piano in cui si trovava originariamente. For example, the curvature of the profiled element can also take place only in one dimension, with the longitudinal axis from the element remaining in the plane in which it was originally located.
