Description

PANNE A SOUDER LES THERMOPLASTIQUESTROUBLE TO WELD THERMOPLASTICS

La présente invention concerne un dispositif pouvant s’adapter aux fers à souder à main pour assembler par soudage les thermoplastiques appelés plus communément les matières plastiques.The present invention relates to a device which can be adapted to hand soldering irons for joining by welding the thermoplastics more commonly called plastics.

Il existe de nombreux dispositifs à main pour réaliser un assemblage des thermoplastiques par soudage, mais ces dispositifs sont généralement destinés aux professionnels et par conséquent relativement coûteux pour un usage occasionnel.There are many hand-held devices for assembling thermoplastics by welding, but these devices are generally intended for professionals and therefore relatively expensive for occasional use.

La présente invention permet de réaliser un cordon ou des points de soudure entre des pièces thermoplastiques au moyen d’un simple fer à souder à main muni d’un dispositif adapté à cet effet et faisant l’objet de la présente invention. Un fil à souder thermoplastique d’apport adapté aux matières à assembler est également nécessaire à cette opération.The present invention makes it possible to produce a bead or weld points between thermoplastic parts by means of a simple hand soldering iron provided with a device suitable for this purpose and which is the subject of the present invention. A thermoplastic welding solder wire suitable for the materials to be assembled is also necessary for this operation.

Selon une première caractéristique, le dispositif (1) comporte un corps de support (2) plein ayant la forme générale d’une panne de fer à souder à main pouvant être droite ou courbée et présentant un canal (3) situé à son extrémité avant constituant une buse de sortie (4) du thermoplastique en fusion ainsi que d’une buse d’entrée (5) du thermoplastique d’apport (9) positionnée à la partie avant du corps de support (2) et présentant un canal (6) communiquant avec le canal (3) du corps de support (2) au moyen du perçage (7) réalisé dans le corps de support (2). Dans un mode de réalisation tel que représenté à la figure 2, la buse (5) est positionnée à la partie supérieur avant du corps de support (2) pour réaliser des soudures facilement accessibles. Dans un autre mode de réalisation tel que représenté à la figure 3 la buse (5) est positionnée sur le côté à la partie avant du corps de support (2) pour réaliser certaines soudures plus difficilement accessibles.According to a first characteristic, the device (1) comprises a solid support body (2) having the general form of a hand soldering iron tip which can be straight or curved and having a channel (3) located at its front end constituting an outlet nozzle (4) of the molten thermoplastic as well as an inlet nozzle (5) of the filler thermoplastic (9) positioned at the front part of the support body (2) and having a channel (6 ) communicating with the channel (3) of the support body (2) by means of the bore (7) produced in the support body (2). In an embodiment as shown in FIG. 2, the nozzle (5) is positioned at the upper front part of the support body (2) to produce easily accessible welds. In another embodiment as shown in FIG. 3, the nozzle (5) is positioned on the side at the front part of the support body (2) to make certain welds which are more difficult to access.

On positionne la buse avant (4) du corps de support (2) chaud au contact des deux pièces à souder (11) et (12) comme indiqué à la figure 1 ce qui provoque la fusion du bord de chacune des deux pièces thermoplastiques tandis qu’on introduit en continu le fil d’apport thermoplastique (9) de même nature que celui desdites pièces à souder dans la buse d’entrée (5) ce qui provoque la fusion dudit fil d’apport qui chemine le long des canaux (6) et (3) et au travers du perçage (7) réalisé sur le corps de support (2) pour sortir par la buse (4) et fusionner avec les bords des pièces à souder (11) et (12) et ainsi former un cordon de soudure (10) grâce au déplacement continu et régulier du fer à souder (13) le long de la ligne de soudure que l’on souhaite réaliser.The front nozzle (4) of the hot support body (2) is positioned in contact with the two parts to be welded (11) and (12) as shown in Figure 1 which causes the edge of each of the two thermoplastic parts to melt while that the thermoplastic filler wire (9) of the same kind as that of said parts to be welded is continuously introduced into the inlet nozzle (5), which causes said filler wire to melt, which travels along the channels ( 6) and (3) and through the bore (7) produced on the support body (2) to exit through the nozzle (4) and merge with the edges of the parts to be welded (11) and (12) and thus form a weld bead (10) thanks to the continuous and regular movement of the soldering iron (13) along the weld line which it is desired to produce.

Avantageusement la buse (5) est solidaire du corps de support (2) au moyen de la soudure (8) de sorte que les canaux (3) et (6) communiquent à leurs extrémités de manière étanche par l’intermédiaire du perçage (7) et forment entre eux de préférence un angle a d’environ 45° dans le sens de leur prolongement. Dans un autre mode de réalisation du dispositif (1), le corps de support (2) et la buse d’entrée (5) peuvent également être réalisés d’un seul tenant par moulage.Advantageously, the nozzle (5) is secured to the support body (2) by means of the weld (8) so that the channels (3) and (6) communicate at their ends in leaktight manner via the bore (7 ) and preferably form between them an angle a of about 45 ° in the direction of their extension. In another embodiment of the device (1), the support body (2) and the inlet nozzle (5) can also be made in one piece by molding.

Selon une autre caractéristique du dispositif (1), le diamètre de la partie arrière du corps de support (2) est identique à celui des pannes de fer à souder à main standards de sorte qu’il puisse être interchangeable avec celles-ci sur le fer à souder.According to another characteristic of the device (1), the diameter of the rear part of the support body (2) is identical to that of the standard hand soldering iron tips so that it can be interchangeable with them on the soldering iron.

Selon une autre caractéristique, le diamètre du canal (6) de la buse d’entrée (5) et celui du perçage (7) réalisé dans le corps de support (2) est avantageusement identique au diamètre du fil thermoplastique d’apport (9) de sorte qu’il n’y ait pas de retour en arrière de matière thermoplastique en fusion lorsqu’on pousse le fil à souder à l’intérieur de ladite buse d’entrée.According to another characteristic, the diameter of the channel (6) of the inlet nozzle (5) and that of the bore (7) produced in the support body (2) is advantageously identical to the diameter of the thermoplastic filler wire (9 ) so that there is no turning back of molten thermoplastic material when the welding wire is pushed inside said inlet nozzle.

Selon une autre caractéristique, le diamètre du canal (6) de la buse d’entrée (5) et celui du perçage (7) sont avantageusement identiques à celui du canal (3) du corps de support (2) de sorte que le débit du thermoplastique d’apport (9) en fusion soit le même que celui d’entrée à l’état solide.According to another characteristic, the diameter of the channel (6) of the inlet nozzle (5) and that of the bore (7) are advantageously identical to that of the channel (3) of the support body (2) so that the flow rate the molten thermoplastic (9) is the same as that of entry in the solid state.

Avantageusement l’ensemble du dispositif est constitué du même matériau que les pannes de fer à souder standards qui sont généralement en cuivre ou dans un alliage de cuivre. L’invention sera mieux comprise à la lecture du mode de réalisation suivant ainsi qu’à la lumière des dessins annexés sur lesquels :Advantageously, the entire device is made of the same material as the standard soldering iron tips, which are generally made of copper or a copper alloy. The invention will be better understood on reading the following embodiment as well as in the light of the appended drawings in which:

La figure 1 représente le dispositif (1) fixé sur un fer à souder à main (13) en position de soudage des pièces thermoplastiques (11) et (12) au moyen du fil d’apport thermoplastique (9).Figure 1 shows the device (1) fixed on a hand soldering iron (13) in the welding position of the thermoplastic parts (11) and (12) by means of the thermoplastic filler wire (9).

La figure 2 représente une coupe partielle du dispositif de soudage (1 ) de la figure 1.FIG. 2 represents a partial section of the welding device (1) of FIG. 1.

La figure 3 représente le dispositif (1) dans un autre mode de réalisation où la buse d’entrée (5) est positionnée sur le coté dans le cas d’un corps de support (2) courbé.Figure 3 shows the device (1) in another embodiment where the inlet nozzle (5) is positioned on the side in the case of a curved support body (2).

Dans un mode de réalisation non limitatif de l’invention et à titre d’exemple d’un fer à souder comportant des pannes de 6mm de diamètre, le corps de support (2) dont le diamètre extérieur est également de 6mm de sorte qu’il soit interchangeable avec les pannes du fer à souder, présente un perçage borgne formant un canal (3) d’un diamètre de 3mm sur une longueur d’environ 20mm à son extrémité avant tel que représenté sur la figure 2. La buse (5) qui est avantageusement de même diamètre que le corps de support (2) et solidaire de celui-ci au moyen de la soudure (8), présente également un perçage débouchant de part en part formant un canal (6) de 3mm de diamètre sur une longueur d’environ 15mm. Les canaux (3) et (6) communiquent à leur extrémité au moyen du perçage (7) réalisé sur le corps de support (2) avantageusement après assemblage de la buse (4) sur le corps de support (2), le canal (6) servant de guide de perçage pour le forêt.In a nonlimiting embodiment of the invention and by way of example of a soldering iron comprising purlins of 6mm in diameter, the support body (2) whose outside diameter is also 6mm so that it is interchangeable with the tips of the soldering iron, has a blind hole forming a channel (3) with a diameter of 3mm over a length of about 20mm at its front end as shown in Figure 2. The nozzle (5 ) which is advantageously of the same diameter as the support body (2) and integral with the latter by means of the weld (8), also has a through hole opening right through forming a channel (6) 3mm in diameter over a length of about 15mm.
