Abstract

The method involves cutting an opening (11) in a connection bar (5) at the level of an orifice to be punched, where the bar made of insulating material is connected to inner and outer metal portions (2, 3) of a section (1) by setting. A punching matrix (13) is introduced into a space (8) enclosed by the opening. The orifice is punched using the matrix, and the matrix is withdrawn from the opening. The opening is formed such that longitudinal edges (12) of the opening are close to end edges (6', 7') of ribs (6, 7) of the metal portions, and the ribs form a punching anvil for the bar. An independent claim is also included for a sash frame.

Description

La présente invention concerne un procédé de poinçonnage, et plus particulièrement un procédé de poinçonnage d'au moins un orifice dans une paroi d'un tronçon d'encadrement de châssis comportant un panneau de remplissage, par exemple un vitrage, ledit tronçon étant formé de deux profilés généralement plans parallèles entre eux reliés par au moins deux barrettes de liaison de manière à former un profil à section transversale fermée, ladite paroi étant constitutive de l'un desdits deux profilés.The present invention relates to a punching method, and more particularly to a method of punching at least one orifice in a wall of a frame framing section comprising a filler panel, for example a glazing unit, said section being formed of two generally planar sections parallel to each other connected by at least two connecting bars so as to form a closed cross section profile, said wall constituting one of said two sections.

De tels encadrements et leur panneau de remplissage, notamment vitrage, respectif associé, formant des ensembles tels que des portes ou fenêtres, sont utilisés dans le domaine de la construction, notamment pour assurer la fermeture d'un espace clos intérieur vis-à-vis de l'extérieur.Such frames and their filler panel, in particular glazing, associated respective forming sets such as doors or windows, are used in the field of construction, in particular to ensure the closure of a closed interior space vis-à-vis from the outside.

On connaît par exemple des châssis dits "à rupture de pont thermique" dont chaque tronçon, à savoir deux montants et deux traverses, est formé de trois parties, un profilé métallique intérieur, un profilé métallique extérieur, et au moins un profilé central en matériau isolant thermiquement tel qu'une matière plastique, appelé barrette isolante. Ces profilés sont assemblés par leurs bords longitudinaux, par exemple par sertissage, et sont installés dans un dormant de fermeture de manière qu'une fois le châssis mis en place, le profilé métallique intérieur soit uniquement en contact avec l'intérieur de l'espace clos par la fermeture et le profilé métallique extérieur soit uniquement en contact avec l'extérieur, le profilé central assurant la liaison mécanique et l'isolation thermique entre le profilé "chaud" et le profilé "froid".For example known so-called "thermal break frames" whose each section, namely two uprights and two crosspieces, is formed of three parts, an inner metal section, an outer metal section, and at least one central section of material thermally insulating material such as a plastic material, called an insulating strip. These profiles are assembled by their longitudinal edges, for example by crimping, and are installed in a closing frame so that once the frame set up, the inner metal section is only in contact with the interior of the space closed by the closure and the external metal profile is only in contact with the outside, the central section ensuring the mechanical connection and the thermal insulation between the "hot" section and the "cold" section.

Lorsque le châssis est un ouvrant, pivotant ou coulissant, des organes de manoeuvre et de verrouillage doivent lui être associés. Ces organes comprennent généralement un verrou disposé entre les deux profilés métalliques, et une poignée de manoeuvre extérieure à l'encadrement reliée au verrou par un arbre de commande. Ces organes de manoeuvre et de verrouillage sont en outre fixés à l'encadrement par des moyens de fixation tels que des vis. Il est donc nécessaire de former dans au moins un des profilés métalliques des orifices de passage pour l'arbre de manoeuvre de la poignée, et pour les moyens de fixation le cas échéant.When the frame is an opening, pivoting or sliding, actuating and locking members must be associated with it. These members generally comprise a latch disposed between the two metal sections, and an external operating handle to the frame connected to the latch by a control shaft. These actuating and locking members are further attached to the frame by fastening means such as screws. It is therefore necessary to form in at least one of the metal profiles passage holes for the operating shaft of the handle, and for the fastening means where appropriate.

La réalisation de ces orifices de passage présente des difficultés. En effet, le tronçon d'encadrement forme un profil tubulaire délimité par les profilés métalliques et les barrettes de liaison. Ce profil tubulaire délimite un espace clos dont il est délicat de percer une paroi.The realization of these passage holes presents difficulties. Indeed, the frame section forms a tubular profile delimited by the metal sections and the connecting bars. This tubular profile defines an enclosed space which is difficult to pierce a wall.

Deux procédés sont actuellement connus pour effectuer cette opération de perçage.Two methods are currently known to perform this drilling operation.

Il est tout d'abord connu d'usiner les orifices, par exemple à l'aide d'une fraiseuse ou d'une perceuse. Une telle opération nécessite toutefois de moyens importants générant des coûts élevés.It is first known to machine the orifices, for example using a milling machine or a drill. Such an operation, however, requires significant resources generating high costs.

C'est la raison pour laquelle les orifices précités sont généralement réalisés par poinçonnage. À cet effet, une tige munie à son extrémité d'une matrice guidée, couramment appelée "souris", est introduite dans le profil fermé par une des extrémités de ce profil. Ce procédé présente toutefois l'inconvénient de la difficulté de maintien et de positionnement de la tige et de la matrice de poinçonnage.This is the reason why the aforementioned orifices are generally made by punching. For this purpose, a rod provided at its end with a guided matrix, commonly called "mouse", is introduced into the closed profile by one end of this profile. This method, however, has the disadvantage of the difficulty of maintaining and positioning the rod and the punching die.

Le document EP 1 839 770 décrit un procédé de ce type. L'invention vise à pallier cet inconvénient.The document EP 1 839 770 describes a process of this type. The invention aims to overcome this drawback.

Plus particulièrement, l'invention a pour but de fournir un procédé de poinçonnage permettant de s'affranchir de l'utilisation d'une "souris".More particularly, the invention aims to provide a punching method to overcome the use of a "mouse".

L'invention a également pour but de fournir un procédé de poinçonnage ne nuisant pas à l'esthétique du châssis dans lequel l'opération est réalisée.The invention also aims to provide a punching process does not detract from the aesthetics of the frame in which the operation is performed.

À cet effet, l'invention a tout d'abord pour objet un procédé de poinçonnage d'au moins un orifice dans une paroi d'un tronçon d'encadrement de châssis comportant un panneau de remplissage, ledit tronçon étant formé de deux profilés généralement plans parallèles entre eux reliés par au moins deux barrettes de liaison de manière à former un espace clos par un profil à section transversale fermée, ladite paroi étant partie constitutive de l'un desdits deux profilés, caractérisé par le fait qu'il comprend les étapes consistant à :

  • découper une ouverture dans une desdites barrettes au niveau des orifices à poinçonner ;
  • introduire une matrice de poinçonnage dans ledit espace clos par ladite ouverture ;
  • poinçonner ledit au moins un orifice en utilisant ladite matrice de poinçonnage ;
  • retirer la matrice de l'ouverture.
To this end, the invention firstly relates to a method of punching at least one orifice in a wall of a frame framing section comprising a filler panel, said section being formed of two profiles generally parallel planes interconnected by at least two connecting bars so as to form a closed space by a profile of closed cross section, said wall being part of one of said two sections, characterized in that it comprises the steps consists in :
  • cutting an opening in one of said bars at the punch holes;
  • introducing a punching die into said enclosed space by said opening;
  • punching said at least one orifice using said punching die;
  • remove the matrix from the opening.

La matrice de poinçonnage n'est donc plus introduite dans le profil longitudinalement au bout d'une tige de maintien et de guidage, mais latéralement par une ouverture préalablement découpée.The punching die is therefore no longer inserted into the profile longitudinally at the end of a holding and guiding rod, but laterally through a previously cut opening.

Dans un mode de réalisation particulier, ladite ouverture est découpée dans la barrette de liaison formant le fond de la feuillure de réception du panneau de remplissage dudit châssis.In a particular embodiment, said opening is cut in the connecting bar forming the bottom of the receiving rabbet of the filling panel of said frame.

Une fois le panneau de remplissage mis en place, l'ouverture n'est donc plus visible, de sorte que la mise en oeuvre du procédé selon l'invention ne nuit en aucune manière à l'esthétique de la fermeture.Once the filling panel set up, the opening is no longer visible, so that the implementation of the method according to the invention does not in any way affect the aesthetics of the closure.

Dans un mode de réalisation particulier, lesdits deux profilés sont des profilés métalliques et lesdites deux barrettes de liaison sont en matériau isolant, ledit châssis étant ainsi à rupture de pont thermique, ladite ouverture étant pratiquée dans une barrette de liaison en matériau isolant.In a particular embodiment, said two profiles are metal profiles and said two connecting bars are of insulating material, said frame thus being thermal break, said opening being formed in a connecting strip of insulating material.

Également dans un mode de réalisation particulier, ladite ouverture est découpée par poinçonnage.Also in a particular embodiment, said opening is cut by punching.

Un tel procédé est particulièrement efficace dans le cas d'un châssis à rupture de pont thermique. En effet, l'ouverture est alors réalisée dans une barrette de liaison en matière plastique pouvant être poinçonnée sans difficulté.Such a method is particularly effective in the case of a thermal break frame. Indeed, the opening is then performed in a plastic connecting bar that can be punched without difficulty.

Plus particulièrement, la barrette de liaison dans laquelle l'ouverture est découpée peut être reliée aux profilés par sertissage, chaque bord longitudinal de ladite barrette étant serti entre deux nervures respectives de chaque profilé, ladite ouverture étant pratiquée de manière que ses bords longitudinaux soient à proximité immédiate des bords d'extrémité desdites nervures, de manière que lesdites nervures forment une enclume de poinçonnage pour ladite barrette.More particularly, the connecting strip in which the opening is cut can be connected to the profiles by crimping, each longitudinal edge of said bar being crimped between two respective ribs of each section, said opening being made so that its longitudinal edges are at immediate proximity of the end edges of said ribs, so that said ribs form a punching anvil for said bar.

Le poinçonnage de la barrette de liaison, même si cette dernière est réalisée en matière plastique, peut en effet provoquer son endommagement, par exemple par éclatement. L'utilisation des nervures de sertissage comme matrice de poinçonnage provoque un effet de cisaillement dans la matière de la barrette qui évite cet inconvénient.The punching of the connecting strip, even if the latter is made of plastic material, can indeed cause its damage, for example by bursting. The use of the crimping ribs as a punching die causes a shearing effect in the material of the bar which avoids this disadvantage.

Également dans un mode de réalisation particulier, la matrice est positionnée transversalement en l'amenant en butée sur la barrette de liaison se trouvant en vis-à-vis de celle dans laquelle l'ouverture est découpée.Also in a particular embodiment, the matrix is positioned transversely by bringing it into abutment on the connecting strip lying opposite the one in which the opening is cut.

En variante, la matrice est positionnée transversalement en l'amenant en butée sur une nervure d'au moins un desdits profilés, intérieure à ladite section transversale fermée.Alternatively, the matrix is positioned transversely by bringing it into abutment on a rib of at least one of said profiles, inside said closed cross section.

Également dans un mode de réalisation particulier, la matrice est positionnée longitudinalement par centrage dans l'ouverture découpée.Also in a particular embodiment, the matrix is positioned longitudinally by centering in the cut opening.

En variante, la matrice est positionnée longitudinalement par calage par rapport à un traçage extérieur sur la paroi à poinçonner.In a variant, the matrix is positioned longitudinally by wedging with respect to an external tracing on the wall to be punched.

Le procédé selon l'invention peut être mis en oeuvre pour la réalisation de tout profilé, notamment entièrement métallique ou entièrement en matière plastique.The method according to the invention can be implemented for the production of any profile, in particular all-metal or entirely of plastic.

La protection s'étend à un tronçon d'encadrement de châssis comportant un panneau de remplissage, obtenu directement par le procédé suivant l'invention.The protection extends to a chassis frame section comprising a filler panel, obtained directly by the method according to the invention.

On décrira maintenant, à titre d'exemple non limitatif, un mode de réalisation de l'invention en référence aux dessins schématiques annexés dans lesquels :

  • la figure 1 est une vue en perspective d'un tronçon d'encadrement de châssis ;
  • la figure 2 est une vue en coupe schématique selon la ligne II-II du tronçon de la figure 3c illustrant une étape du procédé selon l'invention; et
  • les figures 3a à 3c sont des vues en perspective montrant trois étapes de ce procédé permettant d'obtenir un tronçon d'encadrement tel que celui de la figure 1.
One embodiment of the invention will now be described, by way of nonlimiting example, with reference to the appended diagrammatic drawings in which:
  • the figure 1 is a perspective view of a chassis frame section;
  • the figure 2 is a schematic sectional view along the line II-II of the section of the figure 3c illustrating a step of the process according to the invention; and
  • the Figures 3a to 3c are perspective views showing three steps of this method to obtain a framing section such as that of the figure 1 .

On voit à la figure 1 un profil 1 à rupture de pont thermique susceptible de former un montant ou une traverse de châssis de fermeture, notamment châssis ouvrant d'encadrement d'un panneau de remplissage, par exemple un vitrage. Ce profil 1 est constitué dans l'exemple d'un profilé métallique intérieur 2, d'un profilé métallique extérieur 3, reliés par deux barrettes 4 et 5 en matériau isolant thermiquement tel qu'une matière plastique par exemple de type polyamide. La barrette 5 et les profilés 2 et 3 forment une feuillure susceptible de recevoir par exemple un vitrage (non représenté) du châssis. Sur la figure 1, on a représenté les trous 9, 10 à réaliser par poinçonnage sur une paroi 18 du tronçon de profil.We see at the figure 1 a profile 1 with a thermal break capable of forming an amount or a cross member of the closure frame, in particular frame opening frame of a filler panel, for example a glazing. This profile 1 is constituted in the example of an inner metal section 2, an outer metal section 3, connected by two bars 4 and 5 of thermally insulating material such as a plastic material for example of polyamide type. The bar 5 and the sections 2 and 3 form a rebate capable of receiving for example a glazing unit (not shown) of the chassis. On the figure 1 the holes 9, 10 are shown to be punched on a wall 18 of the profile section.

La figure 2 montre que chacune des barrettes 4 et 5 est sertie par chacun de ses bords longitudinaux à un des profilés métalliques 2, 3 entre deux nervures 6 et 7 respectives de ces profilés. Le profil 1 à rupture de pont thermique forme donc un espace clos 8, ouvert seulement aux deux extrémités longitudinales du profil 1.The figure 2 shows that each of the bars 4 and 5 is crimped by each of its longitudinal edges to one of the metal profiles 2, 3 between two respective ribs 6 and 7 of these profiles. Profile 1 to thermal break thus forms a closed space 8, open only at the two longitudinal ends of the profile 1.

Revenant à la figure 1, on voit que le profilé métallique intérieur 2 comporte par exemple un orifice 9 de passage d'un axe (non représenté) de commande d'un verrou de châssis et deux orifices 10 de passage de vis de fixation de la serrure correspondante (non représentée). Il est à noter que l'ensemble des orifices 9, 10 définit un agencement d'orifices de forme variable en fonction du type de serrure, mécanisme, ou analogue qui doit être associé au châssis. Le procédé selon l'invention permet de réaliser tout agencement d'orifices selon les besoins en adaptant un agencement d'orifices correspondant sur la matrice 13 de poinçonnage.Returning to figure 1 it can be seen that the inner metal section 2 comprises, for example, an orifice 9 for the passage of an axis (not shown) for controlling a frame lock and two holes 10 for passing a screw for fixing the corresponding lock (not shown). ). It should be noted that all the orifices 9, 10 defines an arrangement of orifices of variable shape depending on the type of lock, mechanism, or the like that must be associated with the frame. The method according to the invention allows any arrangement of orifices according to needs by adapting a corresponding arrangement of orifices on the punching die 13.

Afin de réaliser les orifices 9 et 10, le procédé selon l'invention prévoit tout d'abord de découper préférentiellement dans la barrette 5 destinée à former le fond de feuillure du panneau de remplissage, une ouverture 11 comme représenté sur la figure 3a. Cette ouverture 11 est ici rectangulaire et est avantageusement réalisée par poinçonnage de la barrette 5. À cet effet, l'ouverture 11 a ses bords longitudinaux 12 à proximité immédiate des bords 6', 7' des nervures 6 et 7 de manière que ces dernières forment une enclume de poinçonnage.In order to produce the orifices 9 and 10, the method according to the invention first of all provides for preferentially cutting, in the bar 5 intended to form the bottom of the rabbet of the filling panel, an opening 11 as shown in FIG. figure 3a . This opening 11 is here rectangular and is advantageously made by punching the bar 5. To this end, the opening 11 has its longitudinal edges 12 in the immediate vicinity of the edges 6 ', 7' of the ribs 6 and 7 so that the latter form an anvil punching.

Une matrice 13 de poinçonnage des orifices 9, 10 est ensuite introduite transversalement au moins en partie dans l'ouverture 11 comme représenté sur les figures 2 et 3c, avec la matrice 13 en position de poinçonnage. Comme représenté sur la figure 2 par les deux flèches, cette introduction est avantageusement réalisée par un premier déplacement transversal de la matrice 13 ou du profil 1 l'un vers l'autre dans un plan sensiblement parallèle à la paroi 18 du tronçon de profil 1, correspondant dans l'exemple au plan du panneau de remplissage (non représenté), de telle sorte que la matrice 13 soit dans l'exemple positionnée transversalement en l'amenant en appui sur la barrette 4 en vis-à-vis de la barrette 5 comportant l'ouverture de passage d'une partie d'extrémité de la matrice.A matrix 13 for punching the orifices 9, 10 is then introduced transversely at least partly into the opening 11 as shown in FIGS. figures 2 and 3c with the matrix 13 in the punching position. As shown on the figure 2 by the two arrows, this introduction is advantageously achieved by a first transverse displacement of the matrix 13 or the profile 1 towards each other in a plane substantially parallel to the wall 18 of the profile section 1, corresponding in the example in the plane of the filling panel (not shown), so that the matrix 13 is in the example positioned transversely by bringing it bearing on the bar 4 vis-à-vis the bar 5 having the opening of passing an end portion of the die.

La surface supérieure 15 de cette extrémité de la matrice 13 est ensuite amenée au contact de la surface intérieure de la paroi 18 dans laquelle le poinçonnage des orifices 9, 10 doit être effectué, tel que représenté sur la figure 2, avantageusement au moyen d'un deuxième déplacement transversal de la matrice 13 ou du profil 1 l'un vers l'autre dans un plan perpendiculaire à la paroi 18 du tronçon de profil 1. Les surfaces de la matrice 13 et de la paroi 18 étant en appui l'une sur l'autre, l'opération de poinçonnage peut être ensuite réalisée sans que la paroi 18 soit déformée par l'effort de poinçonnage comme représenté sur la figure 2. Ce deuxième déplacement transversal en translation, dans l'exemple perpendiculaire au plan du panneau de remplissage, est rendu nécessaire en raison de la présence des nervures 6, 7 de sertissage de la barrette 5 comportant l'ouverture 11 de passage de l'extrémité de la matrice 13. Afin que la surface supérieure 15 de l'extrémité de la matrice 13 puisse entrer en contact avec la surface intérieure de la paroi 18, et en raison de la présence des nervures 6, 7 comme expliqué plus haut, la matrice 13 comporte une partie 16 surélevée d'extrémité, sur laquelle débouchent les orifices 17 pour le poinçon 14, comme représenté plus particulièrement sur la figure 3b, apte donc à venir en appui sur la surface intérieure de la paroi 18 du profilé 2 qui doit être poinçonné.The upper surface 15 of this end of the die 13 is then brought into contact with the inner surface of the wall 18 in which the punching of the orifices 9, 10 must be carried out, as shown in FIG. figure 2 , advantageously by means of a second transverse displacement of the matrix 13 or of the profile 1 towards each other in a plane perpendicular to the wall 18 of the profile section 1. With the surfaces of the matrix 13 and the wall 18 bearing against one another, the punching operation can then be performed without the wall 18 being deformed by the punching force as shown in FIG. figure 2 . This second translational transverse displacement, in the example perpendicular to the plane of the filler panel, is made necessary because of the presence of the crimping ribs 6, 7 of the bar 5 having the opening 11 for passing the end of the filler panel. In order for the upper surface 15 of the end of the die 13 to come into contact with the inner surface of the wall 18, and because of the presence of the ribs 6, 7 as explained above, the die 13 has a raised end portion 16, on which the openings 17 for the punch 14 open, as shown more particularly on the figure 3b , able to come to bear on the inner surface of the wall 18 of the section 2 to be punched.

L'ouverture 11 réalisée de préférence dans la barrette 5 de fond de feuillure, possédera une largeur légèrement supérieure à l'épaisseur de la partie d'extrémité de la matrice 13 qui doit être introduite dans le profil 1 par cette ouverture 11, afin que cette introduction se fasse de préférence librement sans frottement ou accrochage. À cet effet, il sera avantageux de réaliser un orifice 11 dont la largeur correspondra sensiblement à la distance entre les extrémités libres des nervures 6, 7 des deux profilés métalliques intérieur 2 et extérieur 3 du profil 1 associés par les barrettes isolantes 4, 5, comme expliqué plus haut, et l'épaisseur de la partie d'extrémité de la matrice 13 qui doit être introduite dans le profil 1 par cette ouverture 11, sera adaptée en fonction de cette largeur maximale disponible pour l'ouverture 11 entre les extrémités respectives des nervures 6, 7 de chaque profilé 2, 3, pour un profil donné, afin d'être inférieure à cette largeur maximale disponible.The opening 11 preferably made in the rebate bottom strip 5, will have a width slightly greater than the thickness of the end portion of the matrix 13 which must be introduced into the profile 1 through this opening 11, so that this introduction is preferably free without friction or snagging. For this purpose, it will be advantageous to provide an orifice 11 whose width will correspond substantially to the distance between the free ends of the ribs 6, 7 of the two inner and outer metal profiles 2 and 3 of profile 1 associated with the insulating strips 4, 5, as explained above, and the thickness of the end portion of the matrix 13 to be introduced into the profile 1 through this opening 11, will be adapted according to this maximum available width for the opening 11 between the respective ends ribs 6, 7 of each profile 2, 3, for a given profile, in order to be less than this maximum available width.

La matrice 13 est par ailleurs par exemple positionnée longitudinalement par son centrage dans l'ouverture 11, ou de manière alternative, cette matrice 13 est positionnée longitudinalement par calage par rapport à un traçage extérieur sur la paroi à poinçonner.The matrix 13 is also for example positioned longitudinally by its centering in the opening 11, or alternatively, the matrix 13 is positioned longitudinally by wedging relative to an external tracing on the wall to be punched.

Enfin, les orifices 9 et 10 sont poinçonnés à l'aide d'un poinçon 14 en utilisant la matrice 13 de poinçonnage, comme représenté sur les figures 2 et 3c. Cette opération de poinçonnage étant connue en elle-même, elle ne sera pas décrite plus en détail ici. Il est à noter que la figure 2 représente le poinçon 14 engagé dans la matrice 13, contrairement à la figure 3c sur laquelle le poinçon 14 n'est pas encore engagé dans la matrice 13.Finally, the orifices 9 and 10 are punched with a punch 14 using the punching die 13, as shown in FIGS. figures 2 and 3c . This punching operation being known in itself, it will not be described in more detail here. It should be noted that figure 2 represents the punch 14 engaged in the matrix 13, unlike the figure 3c on which the punch 14 is not yet engaged in the matrix 13.

La matrice de poinçonnage 13 est ensuite retirée du profil 1, plus particulièrement de l'espace clos 8, de préférence par deux déplacements transversaux inverses de ceux décrits plus haut pour la mise en place de la matrice dans le profil, afin d'éviter d'accrocher les nervures 6, 7.The punching die 13 is then removed from the profile 1, more particularly from the closed space 8, preferably by two inverse transverse displacements of those described above for the introduction of the matrix in the profile, in order to avoid hang the ribs 6, 7.
