Abstract

A method for forming shaped members by drilling, milling or pushing. The positions of tools are preset with respect to at least one reference surface of the machine. A reference surface of each of the members to be machined is placed on the machine reference surface. The tools are moved in union relative to the member on the machine so that at least one tool in the set can carry out a machining step on at least one side wall of the member. The tools are preset and the member is shaped in such a way that members of various cross sections may be suitably machined from the same set of tools.

La présente invention concerne notamment un procédé de façonnage de profilés, un procédé de fabrication de cadres, des cadres réalisés à partir de profilés ainsi que des profilés de structure particulière.The present invention relates in particular to a method of shaping profiles, a method of manufacturing frames, frames made from profiles as well as profiles of particular structure.
Les techniques actuellement utilisées pour la fabrication des cadres devant constituer des dormants, des ouvrants ou des cadres fixes pour la réalisation de fermetures ou de parois sont très onéreuses du fait que les profilés présentent des sections tout à fait différentes d'un cadre à l'autre de telle sorte que les positions des outils des machines qui sont utilisées pour fabrication des cadres doivent être à chaque fois réglées. C'est pourquoi , il n'est pas possible de faire autrement que de préfabriquer tous les morceaux de profilés devant constituer les ouvrants et les stocker, de fabriquer les cadres constituant ces ouvrants et de les stocker, puis de préfabriquer tous les morceaux de profilés devant constituer les dormants et les stocker, de fabriquer les cadres constituant ces dormants et de les stocker. Il faut ensuite les reprendre les uns après les autres, en les appareillant ou en les assortissant en dimensions, pour la fabrication effective de fermetures.The techniques currently used for the production of frames intended to constitute frames, openings or fixed frames for the production of closures or walls are very expensive because the profiles have sections which are entirely different from one frame to the next. other so that the tool positions of the machines which are used for the production of the frames must be adjusted each time. This is why, it is not possible to do anything other than prefabricate all the pieces of profiles which must constitute the opening elements and store them, manufacture the frames constituting these opening elements and store them, then prefabricate all the pieces of profiles. to constitute the frames and store them, to make the frames constituting these frames and to store them.

It comprises, opposite this groove 47, a free wall 38a which extends its wall opposite its second channel 50 and this groove 47.
Comme le montre la figure 1 , lorsque l'ouvrant 3 est en position fermée, le joint d'étanchéité 56 est en appui contre la paroi 28 du profilé 4 et/ou sa nervure 32, le joint d'étanchéité 22 du profilé 4 est en appui contre l'angle des parois 48 et 49 du profilé 37 et le joint d'étanchéité 25 du profilé 4 est en appui contre la paroi 40 du profilé 37 , le joint 25 et le joint 58 étant également en appui l'un sur l'autre en passant devant le bord de la paroi 40.As shown in Figure 1, when the opening 3 is in the closed position, the seal 56 is in abutment against the wall 28 of the profile 4 and / or its rib 32, the seal 22 of the profile 4 is bearing against the angle of the walls 48 and 49 of the profile 37 and the seal 25 of the profile 4 is pressing against the wall 40 of the profile 37, the seal 25 and the seal 58 also being supported one on the other passing in front of the edge of the wall 40.
Les nervures 32 et 51 et les nervures 33 et 52 sont respectivement situées en vis-à-vis les unes des autres, par rapport au plan médian de la fermeture 1. Les parois 17 et 23 du profilé 4 et la paroi 41 du profilé 37 présentent des formes symétriques par rapport au plan médian de la fermeture 1 et les faces extérieure et intérieure du panneau 57 sont à égales distances des faces des parois 16 et 38, de telle sorte que les formes de la paroi extérieure et de la paroi intérieure de cette fermeture 1 sont sensiblement identiques.The ribs 32 and 51 and the ribs 33 and 52 are respectively located opposite one another, with respect to the median plane of the closure 1. The walls 17 and 23 of the profile 4 and the wall 41 of the profile 37 have symmetrical shapes relative to the median plane of the closure 1 and the outer and inner faces of the panel 57 are at equal distances from the faces of the walls 16 and 38, so that the shapes of the outer wall and the inner wall of this closure 1 are substantially identical.
En outre, les nervures d'accrochage 32, 33 et 51 , 52 sont avantageusement utilisées pour le montage de paumelles et d'organes de verrouillage.In addition, the attachment ribs 32, 33 and 51, 52 are advantageously used for mounting hinges and locking members.
En se repportant maintenant à la figure 2 , on va maintenant décrireune fermeture fixe repérée d'une manière générale par la référence 59. Cette fermeture comprend un cadre repéré d'une mlanière générale par le référence 60 qui de structure identique à celle du cadre 2 de la fermeture 1 , c'est à dire qu'il est constitué à l'aide d'un profilé comprenant un profilé extérieur 5 et un profilé intérieur 6 reliés par des bandes longitudinales de liaison 7. Le cadre 60 porte porte sur son côté intérieur un cadre intermédiaire repéré d'une mlanière générale par le référence 61 qui est construit à partir d'un profilé 62.Referring now to FIG. 2, we will now describe a fixed closure generally identified by the reference 59. This closure comprises a frame identified in a general manner by the reference 60 which has a structure identical to that of the frame 2 of the closure 1, that is to say that it is formed by means of a profile comprising an exterior profile 5 and an interior profile 6 connected by longitudinal connecting strips 7. The frame 60 carries on its inner side an intermediate frame marked with a general strap by the reference 61 which is constructed from a profile 62.
Ce profilé 62 présente une paroi longitudinale 63 -qui s'étend perpendiculairement au plan du cadre 60. Cette paroi 63 porte deux parois longitudinales 64 et 65 qui s'étendent parallèlement au plan du cadre 60, dont les bords d'extrémité sont en prise avec les nervures d'accrochage 31 et 32 du cadre 4, ainsi qu'une paroi longitudinale 66 qui s'étend à partir de son bord intérieur et dont le bord d'extrémité est en appui contre la nervure d'accrochage 32 du profilé 4, parallèlement au plan du cadre 60. En outre, l'autre bord de la paroi 63 présente une nervure longitudinale 67 dans laquelle est engagée la partie longitudinale de fixation d'un joint 68 qui est en appui contre la nervure 20 du profilé 4. La fermeture 59 présente un panneau 69, par exemple en double vitrage, qui s'étend à l'intérieur du cadre intermédiaire 61 et qui prend appui contre" la paroi 63 du profilé 62 par l'intermédiaire d'un joint 70. La partie longitudinale d'un joint longitudinal 7 1 est engagée dans la nervure 24 du profilé 4, la face extérieure du panneau 69 venant en appui contre ce joint.This profile 62 has a longitudinal wall 63 which extends perpendicular to the plane of the frame 60. This wall 63 carries two longitudinal walls 64 and 65 which extend parallel to the plane of the frame 60, the end edges of which are engaged. with the attachment ribs 31 and 32 of the frame 4, as well as a longitudinal wall 66 which extends from its inner edge and the end edge of which bears against the attachment rib 32 of the profile 4 , parallel to the plane of the frame 60. In addition, the other edge of the wall 63 has a longitudinal rib 67 in which is engaged the longitudinal fixing part of a seal 68 which bears against the rib 20 of the profile 4. The closure 59 has a panel 69, for example in double glazing, which extends inside the intermediate frame 61 and which bears against " the wall 63 of the profile 62 by means of a seal 70. The part longitudinal of a longitudinal joint 7 1 e st engaged in the rib 24 of the profile 4, the outer face of the panel 69 coming to bear against this joint.
La fermeture comprend en outre un cadre de maintien repéré d'une manière générale par la référence 72 constitué à partir d'un profilé 73.The closure also includes a retaining frame generally identified by the reference 72 formed from a profile 73.
Ce profilé 73 comprend une paroi 74 qui s'étend parallèlement au plan du cadre 60 et qui constitue la face intérieure de la fermeture 59. A partir de cette paroi 74, le profilé 73 présente une paroi longitudinale 75 dont le bord est en appui contre la face intérieure de la paroi 28 du profilé 4 ou sa nervure 32, une paroi longitudinale 76 qui s'étend devant la paroi 63 du cadre intermédiaire 61 et dont le bord est en prise avec une nervure longitudinale de maintien 77 prévue sur le côté intérieur de cette paroi 63, ainsi qu'une paroi longitudinale 78 , en forme de S, dont le bord longitudinal porte un joint longitudinal 79 qui vient en appui contre la face intérieure du panneau 69.This profile 73 comprises a wall 74 which extends parallel to the plane of the frame 60 and which constitutes the inner face of the closure 59. From this wall 74, the profile 73 has a longitudinal wall 75 whose edge is in abutment the inner face of the wall 28 of the profile 4 or its rib 32, a longitudinal wall 76 which extends in front of the wall 63 of the intermediate frame 61 and whose edge is engaged with a longitudinal retaining rib 77 provided on the inner side of this wall 63, as well as a longitudinal wall 78, in the form of an S, the longitudinal edge of which carries a longitudinal joint 79 which bears against the inner face of the panel 69.
Il s'ensuit que la partie périphérique des faces du panneau 69 est prise entre les joints 71 et 79 et ce panneau 69 est ainsi maintenu solidement par le cadre 72.It follows that the peripheral part of the faces of the panel 69 is taken between the joints 71 and 79 and this panel 69 is thus held securely by the frame 72.
On peut observer que les faces extérieure et intérieure du panneau 69 sont disposées de façon symétrique par rapport à la paroi 16 du profilé 4, qui constitue la face extérieure du cadre 60, et la paroi 74 du cadre 72, qui constitue la face intérieure de la fermeture 59, et que la forme de la paroi 78 du cadre de maintien 72 est sensiblement symétrique et de même forme que les parois 17 et 23 du profilé 4 avec, en prolongement, le joint 71. En outre, les équerres de liaison 34 et 53 présentent la même section et les équerres de liaison 35 et 54 présentent également la même section, les canaux longitudinaux des profilés 4 et 37 étant dimensionnés en conséquence.It can be observed that the outer and inner faces of the panel 69 are arranged symmetrically with respect to the wall 16 of the profile 4, which constitutes the outer face of the frame 60, and the wall 74 of the frame 72, which constitutes the inner face of the closure 59, and that the shape of the wall 78 of the retaining frame 72 is substantially symmetrical and of the same shape as the walls 17 and 23 of the profile 4 with, in extension, the seal 71. In addition, the connecting brackets 34 and 53 have the same section and the connecting brackets 35 and 54 also have the same section, the longitudinal channels of the sections 4 and 37 being dimensioned accordingly.
En se reportant aux figures suivantes, on va maintenant décrire la manière dont les cadres 2 et 36 peuvent être assemblés à l'aide d'une machine portant des outils de serrage et de poinçonnage repérée d'une manière générale par la référence 80.Referring to the following figures, a description will now be given of how the frames 2 and 36 can be assembled using a machine carrying tightening and punching tools generally identified by the reference 80.
Cette machine de poinçonnage 80 comprend deux poutres fixes de guidage 81 et 82, horizontales et parallèles, ainsi que deux poutres de guidage 83 et 84, perpendiculaires au poutre 81 et 82. La poutre 83 est par exemple montée fixe sur les poutres 81 et 82 tandis que la poutre 84 est déplaçable le long des poutres 81 et 82 grâce à des moyens connus d'entraînement repérés par la référence 85.This punching machine 80 comprises two fixed guide beams 81 and 82, horizontal and parallel, as well as two guide beams 83 and 84, perpendicular to the beam 81 and 82. The beam 83 is for example mounted fixed on the beams 81 and 82 while the beam 84 is movable along the beams 81 and 82 by means of known drive means identified by the reference 85.
Les poutres 83 et 84 portent respectivement deux têtes de serrage et de poinçonnage 86 qui sont mobiles le long de ces dernières grâce à des moyens connus d'entraînement repérés par la référence 87.The beams 83 and 84 respectively carry two clamping and punching heads 86 which are movable along the latter by means of known drive means identified by the reference 87.
Chaque tête 86 porte une équerre de serrage 88 dont les branches sont parallèles aux poutres précitées, ces équerres de serrage étant mobiles à 45° par rapport aux poutres précitées grâce par exemple à des vérins 89.Each head 86 carries a clamping bracket 88 whose branches are parallel to the aforementioned beams, these clamping brackets being movable at 45 ° relative to the aforementioned beams, for example by jacks 89.
En outre, chaque tête 86 porte, dans l'exemple, trois doubles poinçons 90 , 9 1 et 92 qui sont pourvus de doigts de poinçonnage et dont les branches sont respectivement associées aux branches des équerres de serrage 88 , ces poinçons étant articulés autour d'axes verticaux 93a et étant susceptibles d'être entraînés en rotation en même temps grâce par exemple à un vérin 93.In addition, each head 86 carries, in the example, three double punches 90, 9 1 and 92 which are provided with punching fingers and whose branches are respectively associated with the branches of the clamping brackets 88, these punches being articulated around of vertical axes 93a and being capable of being driven in rotation at the same time thanks for example to a jack 93.
En outre, la machine 80 présente une surface d'appui 94 qui s'étend horizontalement à un niveau inférieur à celui du poinçon inférieur 90 ainsi que des plots d'appui 95 situés dans sa partie médiane.In addition, the machine 80 has a bearing surface 94 which extends horizontally to a level lower than that of the lower punch 90 as well as bearing pads 95 located in its middle part.
Cette surface d'appui 94 est formée dans l'exemple par des cales amovibles 94a disposées sur la face supérieure d'un banc 94b de machine.This bearing surface 94 is formed in the example by removable wedges 94a arranged on the upper face of a machine bench 94b.
La machine 80 présente en outre des moyens électroniques ou électriques de commande susceptibles de disposer les têtes 80 dans des positions déterminées les unes par rapport aux autres de manière à former entre les quatres équerres de serrage 88 un rectangle de dimension déterminé ainsi que des moyens pour piloter les moyens de déplacement des équerres de serrage 88 et des paires de poinçons 90, 91 et 92.The machine 80 also has electronic or electrical control means capable of placing the heads 80 in determined positions with respect to each other so as to form between the four clamping angles 88 a rectangle of determined size as well as means for control the means for moving the clamping brackets 88 and pairs of punches 90, 91 and 92.
En vue de la fabrication du cadre 2 constitué par le profilé 4 décrit précédemment, on peut utiliser la machine 80 de la manière suivante.For the production of the frame 2 formed by the section 4 described above, the machine 80 can be used in the following manner.
Tout d'abord, après avoir coupé à l'onglet des morceaux de profilé 4 qui constitueront les montants et les traverses du cadre 2, on assemble ces morceaux, par exemple sur une table annexe, en engageant les branches des équerres de liaison 34 et 35 dans les canaux longitudinaux 18 et 29 du profilé 4 de façon à préfabriquer le cadre 2.First of all, after having cut at the tab pieces of profile 4 which will constitute the uprights and the crosspieces of the frame 2, these pieces are assembled, for example on an annex table, by engaging the branches of the connecting brackets 34 and 35 in the longitudinal channels 18 and 29 of the profile 4 so as to prefab the frame 2.
Ensuite, on introduit dans les moyens de commande de la machine 80 les dimensions du cadre à obtenir. Ces derniers positionnent automatiquement les têtes 88 de la machine 80 en des positions telles que la dimension du rectangle déterminé par les équerres de serrage 88 soit légèrement supérieure à la dimension du cadre 2 ainsi préfabriqué.Then, the dimensions of the frame to be obtained are introduced into the control means of the machine 80. The latter automatically position the heads 88 of the machine 80 in positions such that the dimension of the rectangle determined by the clamping brackets 88 is slightly greater than the dimension of the frame 2 thus prefabricated.
On place le cadre 2 préfabriqué entre les équerres de serrage 88 dans une position telle que la paroi 28 du profilé 4, qui constitue un face de référence du cadre 2, soit en appui sur la surface de référence 94 de la machine 80, comme le montre la figure 5.The prefabricated frame 2 is placed between the clamping brackets 88 in a position such that the wall 28 of the profile 4, which constitutes a reference face of the frame 2, is in abutment on the reference surface 94 of the machine 80, like the shows figure 5.
Puis, on actionne les moyens de commande de la machine telle sorte qu'ils enclenchent le processus de fabrication du cadre 2 qui se produit de la manière suivante comme le montrent les figures 5, 6 et 7.Then, the machine control means are actuated so that they initiate the manufacturing process of the frame 2 which occurs as follows as shown in Figures 5, 6 and 7.
Les équerres de serrage 88 des têtes 86 sont actionnées pour se déplacer simultanément, à 45° , et venir prendre, côté extérieur au cadre 2, et compresser les angles de ce cadre 2.The clamping brackets 88 of the heads 86 are actuated to move simultaneously, at 45 °, and come to take, outside the frame 2, and compress the angles of this frame 2.
Puis, les doubles poinçons 90, 9 1 et 92 des têtes de poinçonnage 86 sont actionnés simultanément et pivotent en direction de la paroi périphérique du cadre 5. Ce faisant, les doigts des poinçons inférieurs 90 s'engagent dans la paroi 27 du profilé 4 et les doigts des poinçons supérieurs 92 s'engagent dans la paroi 1 1 du profilé 4 en passant au dessus de sa paroi 13, tandis que les poinçons centraux 91 s'engagent entre les parois 8 et 9 du profilé 4, en direction des bandes de liaison 7, sans toutefois toucher ces parois 8 et 9 et ces bandes 7.Then, the double punches 90, 9 1 and 92 of the punching heads 86 are actuated simultaneously and pivot in the direction of the peripheral wall of the frame 5. In doing so, the fingers of the lower punches 90 engage in the wall 27 of the profile 4 and the fingers of the upper punches 92 engage in the wall 1 1 of the profile 4 passing above its wall 13, while the central punches 91 engage between the walls 8 and 9 of the profile 4, in the direction of the strips of connection 7, without however touching these walls 8 and 9 and these strips 7.
Les poinçons inférieurs 90 déforment localement la paroi 27 du profilé 4 vers l'intérieur et les poinçons supérieurs 92 déforment localement la paroi 15 du profilé 4, les déformations 96 ainsi obtenues s'engageant dans des évidements 97 des équerres de liaison 34 et 35 de manière à fixer solidement les coins du cadre 2.The lower punches 90 locally deform the wall 27 of the profile 4 inwards and the upper punches 92 locally deform the wall 15 of the profile 4, the deformations 96 thus obtained engaging in recesses 97 of the connecting brackets 34 and 35 of so that the corners of the frame are securely attached 2.
Ensuite, les poinçons 90, 91 et 92 et les équerres de serrage 88 des têtes 86 sont ramenés à leur position initiale, libérant le cadre 2 ainsi fabriqué.Then, the punches 90, 91 and 92 and the clamping brackets 88 of the heads 86 are returned to their initial position, releasing the frame 2 thus produced.
Enfin, on retire le cadre 2.Finally, we remove the frame 2.
On va maintenant décrire comment on peut utiliser la machine de poinçonnage 80 pour la fabrication du cadre 36 de l'ouvrant 3 comme le montre les figures 6, 8 et 9, sans modifier les réglages des outils de poinçonnage 90, 91 , et 92 et des équerres de serrage 88.We will now describe how one can use the punching machine 80 for the manufacture of the frame 36 of the opening 3 as shown in FIGS. 6, 8 and 9, without modifying the settings of the punching tools 90, 91, and 92 and clamping brackets 88.
Tout d'abord, on découpe à l'onglet des morceaux de profilé 37 qui constitueront les montants et les traverses du cadre 36 à fabriquer. Sur une table auxiliaire, on engage partiellement les branches des équerres 54 dans les canaux 50 de ces morceaux de manière à constituer un cadre 36 préformé dont l'espace intérieur délimité par les bords intérieurs des parois 49 et 40 du profilé 37 soit supérieur à la surface du panneau 57. Comme précédemment, on programme les dimensions du cadre 36 à fabriquer de manière à ce qu'automatiquement les têtes 86 de la machine 80 se mettent dans des positions déterminées telles que la surface délimitée par les équerres 88 soit supérieure à la surface" du cadre 36 prémonté comme on vient de le décrire.First of all, the profile pieces 37 which will constitute the uprights and the crosspieces of the frame 36 to be manufactured are cut at the tab. On an auxiliary table, the branches of the brackets 54 are partially engaged in the channels 50 of these pieces so as to constitute a preformed frame 36 whose interior space delimited by the interior edges of the walls 49 and 40 of the profile 37 is greater than the panel surface 57. As before, the dimensions of the frame 36 to be manufactured are programmed so that the heads 86 of the machine 80 are automatically placed in determined positions such that the surface delimited by the brackets 88 is greater than the surface " of the frame 36 pre-assembled as just described.
Ensuite, on place le cadre préformé 36 sur la surface de référence 94 de la machine, dans l'espace entre les équerres 88 des têtes 86, dans une position telle que sa paroi 38, qui constitue une face de référence, soit en appui sur la surface de référence 94. On place le panneau 57 en appui sur les plots 95, dans une position telle que son bord périphérique se trouve en face de la rainure 47 du profilé 37.Then, the preformed frame 36 is placed on the reference surface 94 of the machine, in the space between the brackets 88 of the heads 86, in a position such that its wall 38, which constitutes a reference face, is supported on the reference surface 94. The panel 57 is placed in abutment on the studs 95, in a position such that its peripheral edge is located opposite the groove 47 of the profile 37.
Ensuite, on met en route les opérations automatiques suivantes de la machine 80 qui se produisent, comme précédemment de la manère suivante.Then, the following automatic operations of the machine 80 are started, which occur, as previously, in the following manner.
Les équerres de serrage 88 se déplacent en direction des coins du cadre 3 et provoquent le rapprochement des montants et des traverses de ce cadre, en faisant glisser les équerres 54 dans les canaux 50 du profilé 37 , jusqu'à ce que les coins soient en contact. Simultanément, le bord périphérique du panneau 57 s'engage dans la rainure 47 du profilé 37 sur toute la périphérie du cadre 3.The clamping brackets 88 move in the direction of the corners of the frame 3 and bring the uprights and the crosspieces of this frame closer together, by sliding the brackets 54 in the channels 50 of the profile 37, until the corners are in contact. Simultaneously, the peripheral edge of the panel 57 engages in the groove 47 of the profile 37 over the entire periphery of the frame 3.
Ensuite, les trois poinçons 90, 91 et 92 sont actionnés et se déplacent simultanément en direction de la paroi périphérique du cadre 3. Ce faisant, les poinçons centraux 91 déforment localement vers l'intérieur la paroi 48 du profilé 37 et les poinçons inférieurs 90 provoque une déformation locale, vers l'intérieur, de la paroi 42, tandis que les poinçons supérieurs 92 passent au-dessus et à distance de la paroi 47 du profilé 37.Then, the three punches 90, 91 and 92 are actuated and move simultaneously in the direction of the peripheral wall of the frame 3. In doing so, the central punches 91 locally deform inward the wall 48 of the profile 37 and the lower punches 90 causes a local, inward deformation of the wall 42, while the upper punches 92 pass above and at a distance from the wall 47 of the profile 37.
Comme précédemment lors de la fabrication du cadre 2, des déformations 96 s'engagent dans des évidements 97 des branches des équerres de liaison 53 et dans des évidements des branches des équerres de liaison 54.As previously during the manufacture of the frame 2, deformations 96 engage in recesses 97 of the branches of the connecting brackets 53 and in recesses of the branches of the connecting brackets 54.
Enfin, les poinçons 90, 91 et 92 et les équerres de serrage 88 des têtes 86 sont ramenés à leur position initiale. On peut alors retirer l'ouvrant 3 ainsi fabriqué.Finally, the punches 90, 91 and 92 and the clamping brackets 88 of the heads 86 are returned to their initial position. We can then remove the opening 3 thus manufactured.
Ensuite, on peut terminer les opérations de fabrication de la fermeture 1 en disposant les joints décrits précédemment et en montant des paumelles, des organes de verrouillage et tout autre accessoire utile.Then, the operations for manufacturing the closure 1 can be completed by arranging the joints described above and by mounting the hinges, the locking members and any other useful accessory.
Les opérations qui viennent d'être décrites pour la fabrication du cadre 2 et de l'ouvrant 3 sont rendues possibles par le fait que les formes des profilés 4 et 37, la position des poinçons 90, 91 et 92 en hauteur par rapport à la surface de référence 94 de la machine 80 et leur position parallèlement à cette surface de référence 94, la position des équerres de serrage, ainsi que les positions des canaux recevant respectivement les équerres de liaison 34, 35, 53 et 54 sont telles qu'il est possible de provoquer le verrouillage les équerres de liaison 34 et 35 du cadre 4 par déformation des parois de ce dernier grâce aux poinçons 90 et 92 et qu'il est possible de verrouiller les équerres de liaison 53 etThe operations which have just been described for the manufacture of the frame 2 and the opening 3 are made possible by the fact that the shapes of the sections 4 and 37, the position of the punches 90, 91 and 92 in height relative to the reference surface 94 of the machine 80 and their position parallel to this reference surface 94, the position of the clamping angles, as well as the positions of the channels receiving the connection angles 34, 35, 53 and 54 respectively are such that it it is possible to lock the connection brackets 34 and 35 of the frame 4 by deformation of the walls of the latter thanks to the punches 90 and 92 and that it is possible to lock the connection brackets 53 and
54 du profilé 37 du cadre 36 par deformantion des paroi de ce dernier grâce aux poinçons 90 et 91 , sans que dans le premier cas les poinçons 91 ne rencontrent le profilé 4 et dans le second cas que les poinçons 92 ne rencontrent le profilé 37. En conséquence, il suffit de régler une fois pour toutes les positions des poinçons 90, 91 et 92 de la machine 80. Grâce à cela, il est possible de fabriquer sur la machine 80, sans modifier ces réglages, indifféremment des cadres 2 ou des cadres 36 avec ou sans panneau 57. Il y a lieu uniquement d'introduire dans les organes de programmation de la machine 80 la dimension du cadre à obtenir et, après disposition du cadre sur la machine à actionner ses moyens automatique de serrage et de poinçonnage.54 of the profile 37 of the frame 36 by deformation of the walls of the latter thanks to the punches 90 and 91, without in the first case the punches 91 not meeting the profile 4 and in the second case that the punches 92 do not meet the profile 37. Consequently, it suffices to set once and for all the positions of the punches 90, 91 and 92 of the machine 80. Thanks to this, it is possible to manufacture on the machine 80, without modifying these settings, either frames 2 or frames 36 with or without a panel 57. It is only necessary to introduce into the programming members of the machine 80 the dimension of the frame to be obtained and, after the frame has been arranged on the machine to actuate its automatic clamping and punching means .
Ainsi, il est possible de fabriquer à la suite un cadre 2 et un ouvrant 3 pour obtenir une fermeture 1 , répéter ces opérations pour obtenir une autre fermeture 1 , par exemple de dimensions différentes, et/ou fabriquer des cadres 60 en vue de former ultérieurement la fermeture fixe 59.Thus, it is possible to manufacture a frame 2 and an opening 3 to obtain a closure 1, repeat these operations to obtain another closure 1, for example of different dimensions, and / or manufacture frames 60 in order to form subsequently the fixed closure 59.
Bien entendu, il est possible d'exécuter des opérations de façonnage sur les profilés 4 et 37 , éventuellement coupés en morceaux, avant de procéder aux opérations de prémontage des cadres 2 et 36 et/ou d'exécuter des opérations de façonnage sur ces cadres après leur fabrication grâce à des outils préréglés sur des machines adaptées possédant une surface de référence, par exemple des opérations" de perçage ou de fraisage, notamment pour la réalisation de ces opérations à des distances égales de leurs faces de référence précitées ou leurs faces opposées.Of course, it is possible to carry out shaping operations on the sections 4 and 37, possibly cut into pieces, before carrying out the pre-assembly operations for frames 2 and 36 and / or performing shaping operations on these frames after their manufacture using tools preset on suitable machines having a reference surface, for example " drilling " operations or milling, in particular for carrying out these operations at equal distances from their aforementioned reference faces or their opposite faces.
La présente invention ne se limite pas aux exemples ci- dessus décrits. En particulier, les nombres d'outils de poinçonnage et les outils utilisés pourraient être différents. L'invention pourrait s'appliquer également à toutes sortes de formes de profilés adaptés comme on l'a décrit et sur toutes sortes de machines adaptées comme on l'a décrit. The present invention is not limited to the examples described above. In particular, the numbers of punching tools and the tools used could be different. The invention could also apply to all kinds of adapted profile shapes as described and on all kinds of adapted machines as described.
