FILIERE POUR EXTRUDER UN CORDON DE POLYURETHANE PROFILEDIE FOR EXTRUDING A PROFILED POLYURETHANE CORD
La présente invention est relative à une filière pour extruder un cordon de polyuréthane profilé (cordon de The present invention relates to a die for extruding a profiled polyurethane bead (bead of
PUR) sur le pourtour d'une surface vitrée. PUR) around the edge of a glass surface.
Dans les rayons des angles d'une surface vitrée, il est difficile de réaliser un cordon de PUR à profil régulier. La présente invention vise à réaliser une filière à l'aide de laquelle un cordon de PUR à profil de forme régulière puisse être réalisé d'une manière facile et simple In the radii of the angles of a glazed surface, it is difficult to produce a PUR bead with a regular profile. The present invention aims to provide a die using which a PUR bead of regular shape can be produced in an easy and simple manner.
sur tout le pourtour d'une vitre.all around a window.
Cet objectif est atteint grâce au fait que la filière selon l'invention comporte une chambre d'entrée qui se termine par deux conduits d'alimentation servant à produire des parties différentes du cordon de PUR et qu'au moins un desdits deux conduits d'alimentation a une section transversale variable, de façon qu'une variation du débit, par exemple une augmentation du débit pour la partie du cordon de PUR opposée à la vitre, puisse de ce fait être réalisée aux endroits voulus, en particulier dans les rayons This objective is achieved thanks to the fact that the die according to the invention comprises an inlet chamber which ends in two supply conduits serving to produce different parts of the PUR bead and that at least one of said two conduits feed has a variable cross section, so that a variation of the flow, for example an increase in the flow for the part of the PUR bead opposite the glass, can therefore be carried out at the desired locations, in particular in the shelves
des angles d'une surface vitrée.angles of a glass surface.
L'invention va maintenant être décrite à propos d'une forme de réalisation et en référence au dessin, sur lequel: la Fig 1 est une coupe longitudinale de la filière selon l'invention; la Fig 2 est une vue de dessus de la filière selon l'invention; la Fig 3 est une vue de dessous de la filière selon l'invention; la Fig 4 représente une plaque de profil destinée à être fixée à la filière; la Fig 5 est une vue de face de la filière avec la plaque de profil; la Fig 6 est une vue de face de la filière avec le moyen de fixation de la plaque de profil et le disque vertical d'écartement; et la Fig 7 représente une vis de réglage qui peut coopérer avec la filière pour modifier la section The invention will now be described with reference to an embodiment and with reference to the drawing, in which: FIG. 1 is a longitudinal section of the die according to the invention; Fig 2 is a top view of the die according to the invention; Fig 3 is a bottom view of the die according to the invention; Fig 4 shows a profile plate intended to be fixed to the die; Fig 5 is a front view of the die with the profile plate; Fig 6 is a front view of the die with the fixing means of the profile plate and the vertical spacer disc; and Fig 7 shows an adjustment screw which can cooperate with the die to modify the section
transversale d'un conduit d'alimentation. cross section of a supply duct.
Une filière 1, représentée sur les figures 1 à 3, est fixée à un système d'extrusion (non représenté) à l'aide d'un filetage 2 Le filetage 2 entoure une chambre 3 d'entrée dans laquelle on fait passer une matière constituée de polyuréthane (PUR) liquide provenant du système d'extrusion La répartition du flux de matière peut être optimalisée à l'aide de la profondeur de vissage du filetage 2 sur le système d'extrusion, compte tenu des différentes valeurs de hauteur de la filière et donc des A die 1, shown in Figures 1 to 3, is attached to an extrusion system (not shown) using a thread 2 The thread 2 surrounds an inlet chamber 3 through which a material is passed made of liquid polyurethane (PUR) from the extrusion system The distribution of the material flow can be optimized using the screw depth of thread 2 on the extrusion system, taking into account the different height values of the sector and therefore
différentes dimensions de la chambre 3 d'entrée. different dimensions of the entrance bedroom 3.
Lorsque la profondeur de vissage voulue est atteinte, la position est fixée Cela peut se faire, par exemple, à l'aide d'une vis (non représentée) qui est disposée transversalement à la paroi 4 et repose sur le filetage correspondant du système d'extrusion Si le filetage ne doit pas s'user, il est également possible d'utiliser un f iletage rapporté qui est disposé d'une manière réglable transversalement à la paroi 4 Les flancs du f iletage sont ensuite serrés les uns par rapport aux autres par un When the desired screwing depth is reached, the position is fixed This can be done, for example, using a screw (not shown) which is arranged transversely to the wall 4 and rests on the corresponding thread of the system d extrusion If the thread is not to wear out, it is also possible to use an insert thread which is arranged in an adjustable manner transversely to the wall 4 The sides of the thread are then tightened with respect to each other by a
mouvement d'ajustement.adjustment movement.
La chambre 3 d'entrée se termine par un premier et un second conduits d'alimentation 5 et 6 dont les extrémités inférieures sont respectivement définies par une plaque de profil 7 La plaque de profil 7 comporte une empreinte de moulage du profil voulu pour un cordon de polyuréthane The inlet chamber 3 ends with a first and a second supply duct 5 and 6, the lower ends of which are respectively defined by a profile plate 7 The profile plate 7 has a mold impression of the desired profile for a bead polyurethane
(cordon de PUR) (Fig 4).(PUR bead) (Fig 4).
La plaque de profil 7 est introduite dans un logement de la filière (Fig 5) et est fixé à celui-ci Ce montage s'effectue par l'intermédiaire d'une plaque de serrage 8 conçue pour être vissée sur la filière à l'aide d'une vis 9 The profile plate 7 is introduced into a housing of the die (Fig 5) and is fixed to this. This mounting is carried out by means of a clamping plate 8 designed to be screwed onto the die with the using a screw 9
et comprime la plaque le profil 7 contre la filière 1. and compresses the plate the profile 7 against the die 1.
Ainsi, la plaque de profil 7 est montée de façon à pouvoir être remplacée pour obtenir n'importe quel profil réalisé Thus, the profile plate 7 is mounted so that it can be replaced to obtain any profile produced
sur différentes plaques de profil.on different profile plates.
Le premier conduit d'alimentation 5 a une section transversale variable, grâce à quoi le débit peut être modifié Cette opération de réglage peut par exemple être effectuée à l'aide d'une vis de réglage 10 qui est disposée transversalement à la paroi 4 de la filière 1 et fait saillie dans le conduit d'alimentation 5 Comme représenté sur la Fig 7, la vis de réglage 10 a un rayon R pour déterminer différents débits du PUR par différentes positions angulaires de la vis de réglage 10 Bien entendu, d'autres dispositifs d'obturation connus que la vis de réglage 10 peuvent également être utilisés pour commander le débit En outre, la section transversale du second conduit d'alimentation 6 peut elle aussi être modifiée si nécessaire. De préférence, le débit de matière est commandé automatiquement A cette fin, un moyen de détection détecte les parties formant rayons des angles de la vitre, un moyen de calcul est prévu pour déterminer les débits nécessaires dans les conduits d'alimentation 5 et 6, et un moyen de commande règle le moyen de réglage pour modifier la section transversale du conduit d'alimentation 5 ou celles des conduits d'alimentation 5 et 6. Comme représenté sur la Fig 6, un disque vertical d'écartement 11 est disposé d'une manière réglable sur la filière 1 pour obtenir un écartement uniforme entre la The first supply conduit 5 has a variable cross section, whereby the flow rate can be modified This adjustment operation can for example be carried out using an adjustment screw 10 which is arranged transversely to the wall 4 of the die 1 and projects into the supply conduit 5 As shown in FIG. 7, the adjustment screw 10 has a radius R to determine different flow rates of the PUR by different angular positions of the adjustment screw 10 Of course, from other known closure devices that the adjusting screw 10 can also be used to control the flow rate. In addition, the cross section of the second supply duct 6 can also be modified if necessary. Preferably, the flow of material is automatically controlled. To this end, a detection means detects the ray-forming parts of the corners of the glass, a calculation means is provided for determining the flow rates required in the supply conduits 5 and 6, and a control means adjusts the adjustment means to modify the cross section of the supply duct 5 or those of the supply ducts 5 and 6. As shown in FIG. 6, a vertical spacer disc 11 is arranged with an adjustable manner on the die 1 to obtain a uniform spacing between the
filière 1 et la surface vitrée.sector 1 and the glass surface.
Il est également possible aménager plus de deux conduits d'alimentation dans la filière 1 pour réaliser des It is also possible to arrange more than two supply conduits in the die 1 to produce
cordons de PUR à profils spéciaux. PUR cords with special profiles.
