Description

Dispositif support pour buse amovible et réglable pour pistolet à pulvérisation thermique Support device for removable and adjustable nozzle for thermal spray gun
La présente invention concerne un dispositif pour fixer au moins une buse à revêtement notamment enduit thermoplastique en poudre de façon amovible et réglable, dans un sens radial et transversal pour un pistolet à pulvérisation thermique.The present invention relates to a device for fixing at least one powder coated thermoplastic coating nozzle in a removable and adjustable manner, in a radial and transverse direction for a thermal spray gun.
Les pistolets à pulvérisation thermique utilisent deux gaz, l'un formant le carburant et l'autre formant le comburant. Les pistolets à pulvérisation thermique utilisent un comburant pur, tel que de l'oxygène et un carburant (acétylène ou un tout autre combustible gazeux ou liquide), ce qui leur assure une température de flamme très haute. Ces pistolets à pulvérisation thermique ont toutefois un coût d'achat relativement élevé et un coût d'utilisation et d'entretien très important, du fait des bouteilles de gaz qu'il est nécessaire d'acheter et de recharger. Ils sont peu maniables, par leur poids et volume, du fait que la combustion est interne et ils ont des buses à revêtement fixes, avec un réglage de puissance de flamme peu ou pas modulable. Avec les modèles à jet de poudre extérieur ou combustion interne, il n'est pas possible de changer l'angle du jet de poudre et la distance de la buse par rapport à la flamme. On est donc dans l'impossibilité de maîtriser son nuage de revêtement en fonction du support. En effet, un support de petite section à recouvrir de revêtement notamment enduit thermoplastique en poudre, demande une puissance de flamme et un angle de jet différent, par rapport à un plan plat de plusieurs mètres carrés. Pour projeter les thermoplastiques en poudre qui n'acceptent pas le contact avec la flamme pour les fondre, on utilise les calories dégagées par la flamme. Pour cela on place les buses dans un plan α tangent et au-dessus de la flamme ce qui a pour effet de projeter les thermoplastiques en poudre parallèlement ou avec très peu d'angle, par rapport à l'axe longitudinalement de la flamme ce qui est suffisant pour les fondre. Si la cible est conductible on règle les buses à enduit thermoplastique en poudre de telle sorte que le thermoplastique projeté se dépose sur la cible juste au-dessus du secteur ou frappe la flamme. Les modèles à jet de poudre extérieur ou à combustion interne sont dans l'impossibilité de s'adapter à des poudres de nouvelle génération ou à bi composant, car leur buse est solidaire du corps de l'appareil. Le coût d'achat, d'utilisation et d'entretien rendent ces pistolets à pulvérisation thermique complexes et guère abordables pour des artisans ou des petites entreprises. II existe un dispositif, préchauffage d'air ou/et gaz permettant de réaliser un chalumeau en mono gaz, butane ou propane et pour certain, avec un complément électrique.Thermal spray guns use two gases, one forming the fuel and the other forming the oxidant. The thermal spray guns use a pure oxidizer, such as oxygen and a fuel (acetylene or any other gaseous or liquid fuel), which ensures a very high flame temperature. These thermal spray guns, however, have a relatively high purchase cost and a very high cost of use and maintenance, because of the gas cylinders that it is necessary to purchase and refill. They are not very manageable, by their weight and volume, because the combustion is internal and they have fixed coating nozzles, with a flame power setting little or no modulable. With the external powder jet or internal combustion models, it is not possible to change the angle of the powder jet and the distance of the nozzle from the flame. It is therefore impossible to control its coating cloud depending on the support. In fact, a support of small section to cover coating including thermoplastic powder coating, requires a flame power and a different jet angle, compared to a flat plane of several square meters. To project powdered thermoplastics that do not accept the contact with the flame to melt them, the calories released by the flame are used. For this purpose, the nozzles are placed in a tangent plane α and above the flame, which has the effect of projecting the thermoplastics in powder in parallel or with a very small angle, with respect to the longitudinal axis of the flame. is enough to melt them. If the target is conductive, the thermoplastic powder-coated nozzles are adjusted such that the projected thermoplastic is deposited on the target just above the sector or strikes the flame. Models with external powder or internal combustion are unable to adapt to new generation powders or bi-component, because their nozzle is integral with the body of the device. The cost of purchase, use and maintenance make these thermal spray guns complex and not affordable for artisans or small businesses. There is a device, preheating air and / or gas for making a torch in mono gas, butane or propane and for some, with an electric supplement.
Ces chalumeaux comportent une structure d'accrochage de flamme. Cette flamme est longue, large et à une température et une vitesse très élevées. On peut facilement modifier les paramètres de taille, de température et de vitesse de soufflage de la flamme et ce, par réglage sur le chalumeau. En contre partie, la tuyère atteint des températures extrêmement chaudes ~ 600° C, se propageant sur l'ensemble de la tuyère. Il n'existe pas à ce jour de dispositif pouvant modifier un chalumeau mono ou bi carburants, pour qu'il puisse être utilisé en tant que pistolet à pulvérisation thermique, de manière simple, rapide à mettre en œuvre et à un coût réduit, il est également actuellement impossible de changer les buses à revêtement notamment enduit thermoplastique en poudre ou leur angle de jet de revêtement notamment enduit thermoplastique en poudre, ni d'avoir la possibilité de remonter ou de descendre le plan α par rapport à l'axe longitudinalement de la flamme, en fonction de la composition du revêtement en poudre ou de la pièce à recouvrir et aux contraintes liées aux endroits à recouvrir.These torches have a flame attachment structure. This flame is long, wide and at a very high temperature and speed. The flame size, temperature, and speed settings can easily be changed by setting the torch. In counterpart, the nozzle reaches extremely hot temperatures ~ 600 ° C, spreading over the entire nozzle. There is currently no device that can modify a single torch or bi fuels, so that it can be used as a thermal spray gun, in a simple, quick to implement and at a reduced cost, it It is also currently not possible to change the coating nozzles including powdered thermoplastic coating powder coating angle or powder coating thermoplastic powder, nor to have the possibility to go up or down the plane α with respect to the longitudinal axis of the flame, depending on the composition of the powder coating or the part to be covered and the constraints related to the areas to be covered.
Le dispositif, selon l'invention, permet de remédier à cet inconvénient. En effet, il comporte selon une première caractéristique, au moins un bras fixé à la tuyère ou au corps du pistolet qui comprend un axe de rotation verrouillable , ce qui permet de fixer soit directement soit par l'intermédiaire d'un deuxième bras percé à ses extrémités, l'anneau enserrant la buse ayant le même plan α que la tuyère du pistolet, pour ensuite enserrer et rendre solidaire de l'ensemble, une buse à revêtement notamment enduit thermoplastique en poudre. L'anneau enserrant la buse est monté sur un axe rotatif, avec un déplacement vertical, ces deux fonctions sont verrouillables. Le déplacement de cette buse à revêtement notamment enduit thermoplastique en poudre se fait de façon radiale sur l'axe transversal de la flamme du chalumeau. Quand l'ensemble est totalement monté, le jet de la buse ou des buses à revêtement notamment enduit thermoplastique en poudre, a un déplacement radial sur l'axe transversal de la flamme du chalumeau et, par réglage manuel des supports en rotation sur leur axe de rotation, qui les relient entre eux, on peut modifier l'angle du jet de revêtement notamment enduit thermoplastique en poudre sur la flamme, tout en faisant coulisser la buse à revêtement notamment enduit thermoplastique en poudre dans son anneau de maintien, on peut approcher ou éloigner la buse à revêtement notamment enduit thermoplastique en poudre de la flamme ainsi que la possibilité de remonter ou de descendre le plan α par rapport à l'axe longitudinale de la flamme.The device according to the invention overcomes this disadvantage. Indeed, it comprises according to a first feature, at least one arm attached to the nozzle or the gun body which comprises a locking axis of rotation, which allows to fix either directly or via a second pierced arm to its ends, the ring enclosing the nozzle having the same plane α as the nozzle of the gun, to then grip and make integral with the assembly, a coating nozzle including thermoplastic powder coating. The ring enclosing the nozzle is mounted on a rotary axis, with a vertical movement, these two functions are lockable. The movement of this powder coated thermoplastic coating nozzle is radially on the transverse axis of the flame of the torch. When the assembly is completely assembled, the jet of the nozzle or nozzles coated including thermoplastic powder coating, has a radial displacement on the transverse axis of the torch flame and, by manual adjustment of the rotational supports on their axis of rotation, which connect them to one another, it is possible to modify the angle of the coating jet, in particular powdered thermoplastic coating on the flame, while sliding the powder coated thermoplastic coating nozzle in its holding ring, it is possible to approach or remove the nozzle coating including thermoplastic powder coating of the flame and the possibility of go up or down the plane α relative to the longitudinal axis of the flame.
