DESCRIZIONE DESCRIPTION
Il presente modello riguarda un terminale anteriore del corpo di torcia per saldature Mig e Plasma che verrà descritto come Ugello e della punta guidarlo della stessa torcia, secondo la parte generale della rivendicazione 1. The present model relates to a front terminal of the torch body for Mig and Plasma welding which will be described as a nozzle and of the tip guiding it of the same torch, according to the general part of claim 1.
E3 noto che vi sono svariati tipi di torce per saldatura a Mig o Plasma e che vi sono molti terminali anteriori e punte guidafilo costruiti in leghe di rame o leghe di ottone, sia cromate o non, con forme coniche o cilindriche di varie misure, aventi attacchi a vite oppure ad innesto automatico, raffreddati ad acqua o aria, dove è risaputo che nell’operazione di saldatura avvengono dei ritorni di materiali fusi entro all’ugello ed alle punte guidafilo, formando scorie di varie dimensioni che con il gas emanato per il raffreddamento della punta, ostruiscono o deviano l’uscita del filo per saldatura inceppando la stessa operazione. It is known that there are various types of Mig or Plasma welding torches and that there are many front terminals and wire guide tips made of copper alloys or brass alloys, whether chromed or not, with conical or cylindrical shapes of various sizes, having screw or automatic coupling connections, cooled by water or air, where it is known that in the welding operation there are returns of molten materials within the nozzle and the wire guide tips, forming slag of various sizes that with the gas emitted for the tip cooling, obstructing or deflecting the outlet of the solder wire, jamming the same operation.
I ritrovati per eliminare tale inconveniente consistono in vari tipi di gas iniettati tramite bombolette spray manualmente entro l’ugello della torcia, ma l effetto ricavato non risulta sufficiente al fabbisogno. The inventions to eliminate this drawback consist of various types of gases injected by means of spray cans manually into the nozzle of the torch, but the effect obtained is not sufficient for the needs.
Scopo del presente modello è quello di realizzare un dispositivo del tipo descritto in precedenza che sia esente dagli inconvenienti di cui sopra risultano, in particolare, di semplice costruzione e di uso efficace. The object of the present model is to provide a device of the type described above which is free from the above drawbacks and, in particular, are simple in construction and effective in use.
Ciò si ottiene, secondo il modello, prevedendo un rivestimento all’ugello della torcia e alle punte guidafilo, in materiale ceramico, resistente al calore, avente come pregio la superfìcie cristallizzata, dove le scorie non possono attaccarsi , formare ostruzioni o altri depositi che rendono impossibile la saldatura, inoltre, saranno eliminati i gas aggiuntivi, che, oltre al costo, determinano un grave danno all’ambiente. This is achieved, according to the model, by providing a coating to the nozzle of the torch and the wire guide tips, in ceramic material, resistant to heat, having as a value the crystallized surface, where the slag cannot stick, form obstructions or other deposits that make impossible to weld, moreover, the additional gases will be eliminated, which, in addition to the cost, cause serious damage to the environment.
Queste ed altre caratteristiche verranno ora qui di seguito descritte in dettaglio, facendo riferimento alla tavola di disegno allegata, dove: These and other features will now be described in detail below, referring to the attached drawing table, where:
La fig. 1 della tav. 1 rappresenta una vista dell’ugello di cui al modello, in condizioni di effettiva utilizzazione. Fig. 1 of table 1 represents a view of the nozzle referred to in the model, in conditions of actual use.
La fig. 2 rappresenta una vista della punta guidafilo di cui al modello, in condizioni di effettiva utilizzazione. Fig. 2 shows a view of the wire guide tip of the model, in conditions of actual use.
La fig. 3 rappresenta una vista in sezione del suddetto ugello. Fig. 3 represents a sectional view of the aforesaid nozzle.
La fig. 4 rappresenta una vista in sezione della suddetta punta guidafilo. Fig. 4 represents a sectional view of the aforesaid wire guide tip.
Come visibile nelle fig. 3-4- , il dispositivo di cui al modello prevede che all’interno e parte all’esterno dell'ugello, e della punta guidafilo, sia rivestito in ceramica 5-5a , lasciando libere le parti per l'ancoraggio alla torcia, dove, data la proprietà di superfìcie liscia e inattaccabile della ceramica , avremmo una struttura che non permette l'attacco delle scorie del filo per saldatura, scorie prodotte dai gas emanati alla fusione del contatto e dal materiale stesso. As can be seen in figs. 3-4-, the device of the model provides that the inside and part of the outside of the nozzle, and of the wire guide tip, is coated with ceramic 5-5a, leaving the parts free for anchoring to the torch, where Given the smooth and unassailable surface properties of the ceramic, we would have a structure that does not allow the attack of the welding wire slag, slag produced by the gases emanating from the melting of the contact and by the material itself.
Un’altra caratteristica favorevole al dispositivo di cui al modello, è dovuta alla eliminazione di prodotti aggiuntivi per eliminazione, parziale, dell’inconveniente scorie, quali i gas da iniettare manualmente tramite bombolette spray, aventi inoltre un costo aggiuntivo, e altri sistemi isolanti di poca efficacia. Another favorable feature of the device referred to in the model is due to the elimination of additional products by partial elimination of the inconvenient waste, such as gases to be injected manually through spray cans, also having an additional cost, and other insulating systems of little effectiveness.
Inoltre vengono eliminati i tempi persi nella pulitura degli ugelli, fig. 6-6a- e delle punte guidafilo con attrezzi di vario tipo, che nell’opera possono provocare danni alla struttura della torcia. Furthermore, the time lost in cleaning the nozzles is eliminated, fig. 6-6a- and wire guide tips with various types of tools, which in the work can cause damage to the structure of the torch.
Il prodotto di cui al modello si estende anche all’utilizzo degli ugelli inseriti nelle torce per lavorazioni al Plasma, aventi anch’essi le problematiche di cui sopra sono descritte, dove verrà posta la ricopertura in materiale ceramico nello stesso sistema degli ugelli per la saldatura. The product referred to in the model also extends to the use of the nozzles inserted in the torches for Plasma processing, also having the problems described above, where the ceramic coating will be placed in the same system of the nozzles for welding .
