"MOLA SUPERABRAS IVA , PARTICOLARMENTE PER MACCHINE RETTILINEE E BILATERALI PER LA RETTIFICA DEL VETRO" "MOLA SUPERABRAS IVA, ESPECIALLY FOR STRAIGHT AND BILATERAL MACHINES FOR GLASS GRINDING"
DESCRIZIONE DESCRIPTION
Il presente trovato riguarda una mola superabrasiva, particolarmente per macchine rettilinee e bilaterali per la rettifica del vetro. The present invention relates to a superabrasive wheel, particularly for straight and bilateral machines for grinding glass.
Come à ̈ noto, nelle macchine rettilinee e bilaterali per la rettifica del vetro sono impiegate mole superabrasive che consentono di lavorare i bordi delle lastre di vetro. As is known, superabrasive wheels are used in straight and double-sided glass grinding machines to work the edges of the glass sheets.
Normalmente, i dispositivi di montaggio delle mole superabrasive si basano su serraggio meccanico dell'anello diamantato, ossia l'anello che consente la lavorazione della mola, al corpo della mola stessa. Inoltre, la mola à ̈ accoppiata ad un mandrino che consente di impartire una rotazione alla mola. Normally, the mounting devices of superabrasive wheels are based on mechanical tightening of the diamond ring, that is the ring that allows the grinding wheel to be machined, to the body of the wheel itself. Furthermore, the grinding wheel is coupled to a spindle which allows to impart a rotation to the grinding wheel.
L'accoppiamento meccanico dell'anello diamantato con il corpo della mola fa si che la sostituzione dell'anello, operazione frequente quando di effettuano lavorazioni mediante una mola, debba comportare tempi di sostituzione lunghi, in quanto la connessione meccanica deve essere rimossa dall'operatore, e quindi il fermo macchina incide significativamente sulla lavorazione della macchina che ha a bordo la mola. The mechanical coupling of the diamond ring with the body of the wheel means that the replacement of the ring, a frequent operation when working with a wheel, must involve long replacement times, as the mechanical connection must be removed by the operator , and therefore the machine stop significantly affects the machining of the machine that has the grinding wheel on board.
Compito precipuo del presente trovato à ̈ quello di realizzare una mola superabrasiva, particolarmente per macchine rettilinee e bilaterali per la rettifica del vetro, che abbia un sistema di attacco dell'anello diamantato al corpo della mola che sia più efficiente rispetto ai sistemi meccanici di tipo noto. The main task of the present invention is to provide a superabrasive wheel, particularly for straight and bilateral machines for glass grinding, which has a system for attaching the diamond ring to the body of the wheel which is more efficient than mechanical systems of the type known.
Nell'ambito di questo compito, uno scopo del presente trovato à ̈ quello di realizzare una mola superabrasiva in cui l'accoppiamento tra anello diamantato e corpo della mola, e quindi la sostituzione dell'anello diamantato, possa avvenire con impiego di utensili minimo. Within this aim, an object of the present invention is to provide a superabrasive wheel in which the coupling between the diamond ring and the body of the wheel, and therefore the replacement of the diamond ring, can take place with the use of minimal tools.
Un altro scopo del presente trovato à ̈ quello di realizzare una mola superabrasiva in cui il sistema di accoppiamento ideato tra l'anello diamantato e la mola sia in grado di rimanere invariato nel tempo mantenendo la sua efficacia. Another object of the present invention is to provide a superabrasive wheel in which the coupling system conceived between the diamond ring and the wheel is able to remain unchanged over time while maintaining its effectiveness.
Non ultimo scopo del presente trovato à ̈ quello di realizzare una mola superabrasiva che sia di elevata affidabilità , di relativamente semplice realizzazione ed a costi competitivi. Not least object of the present invention is to provide a superabrasive wheel which is highly reliable, relatively simple to manufacture and at competitive costs.
Questo compito, nonché questi ed altri scopi che meglio appariranno in seguito, sono raggiunti da una mola superabrasiva, particolarmente per macchine rettilinee e bilaterali per la rettifica del vetro, comprendente un corpo della mola a cui à ̈ atto ad essere applicato un anello diamantato, caratterizzata dal fatto che detto corpo della mola prevede un anello magnetico atto ad esercitare una forza magnetica per l'accoppiamento tra detto corpo della mola e detto anello diamantato. This task, as well as these and other purposes that will appear better later, are achieved by a superabrasive grinding wheel, particularly for straight and bilateral machines for glass grinding, comprising a wheel body to which a diamond ring can be applied. , characterized in that said body of the wheel has a magnetic ring capable of exerting a magnetic force for coupling between said body of the wheel and said diamond ring.
Ulteriori caratteristiche e vantaggi del trovato risulteranno maggiormente dalla descrizione di una forma di realizzazione preferita, ma non esclusiva, della mola superabrasiva secondo il presente trovato, illustrata a titolo indicativo e non limitativo negli uniti disegni, in cui: Further characteristics and advantages of the invention will become clearer from the description of a preferred but not exclusive embodiment of the superabrasive wheel according to the present invention, illustrated by way of non-limiting example in the accompanying drawings, in which:
la figura 1 illustra in vista in sezione trasversale, in esploso, una prima forma di realizzazione della mola secondo il trovato; Figure 1 is an exploded cross-sectional view of a first embodiment of the grinding wheel according to the invention;
la figura 2 illustra in vista in sezione la mola della figura 1; Figure 2 is a sectional view of the grinding wheel of Figure 1;
la figura 3 illustra in vista in sezione trasversale, in esploso, una seconda forma di realizzazione della mola secondo il trovato; Figure 3 is an exploded view in cross section of a second embodiment of the grinding wheel according to the invention;
la figura 4 illustra in vista in sezione trasversale la mola della figura 3; Figure 4 is a cross-sectional view of the grinding wheel of Figure 3;
la figura 5 illustra in vista in pianta l'anello diamantato della mola secondo il presente trovato . Figure 5 is a plan view of the diamond ring of the grinding wheel according to the present invention.
Con riferimento alle figure, in cui a numeri uguali fanno riscontro elementi uguali o funzionalmente uguali, la mola superabrasiva secondo il trovato, globalmente indicata dal numero di riferimento 1, comprende un corpo 2 della mola, atto ad essere fissato ad un mandrino 7, mediante una cavità di accoppiamento 3. Il corpo della mola opportunamente presenta, lungo il suo perimetro, un anello 4 magnetico atto a generare un campo magnetico necessario per fissare un anello diamantato sul corpo 2 della mola. Il numero di riferimento 5 indica l'anello diamantato che viene accoppiato magneticamente al corpo 2 della mola. With reference to the figures, in which identical numbers are matched by identical or functionally identical elements, the superabrasive wheel according to the invention, globally indicated by the reference number 1, comprises a body 2 of the wheel, adapted to be fixed to a mandrel 7, by means of a coupling cavity 3. The body of the wheel suitably has, along its perimeter, a magnetic ring 4 suitable for generating a magnetic field necessary to fix a diamond ring on the body 2 of the wheel. The reference number 5 indicates the diamond ring which is magnetically coupled to the body 2 of the grinding wheel.
Il campo magnetico generato ha valenza nel senso assiale e torsionale. La trasmissione della forza magnetica di serraggio dall'anello magnetico 4 all'anello diamantato 5 Ã ̈ affidata semplicemente all'avvicinamento/contatto tra anello magnetico 4 e anello diamantato 5. The generated magnetic field has value in the axial and torsional sense. The transmission of the magnetic clamping force from the magnetic ring 4 to the diamond ring 5 is simply entrusted to the approach / contact between the magnetic ring 4 and the diamond ring 5.
In questo modo, l'accoppiamento tra l'anello diamantato 5 e il corpo 2 della mola può avvenire senza l'ausilio di utensili. In this way, the coupling between the diamond ring 5 and the body 2 of the grinding wheel can take place without the aid of tools.
Al fine di effettuare un agevole montaggio dell'anello diamantato 5 al corpo 2 della mola à ̈ opportunamente dotato di una o più cavità 6, ad esempio angolarmente equidistanti, le quali consentono l'inserimento di un cacciavite piatto che viene interposto tra il corpo della mola e l'anello diamantato 5. In order to carry out an easy assembly of the diamond ring 5 to the body 2 of the wheel, it is suitably equipped with one or more cavities 6, for example angularly equidistant, which allow the insertion of a flat screwdriver which is interposed between the body of the grinding wheel and diamond ring 5.
Opportunamente, l'anello magnetico 4 viene annegato entro il corpo 2 della mola. Conveniently, the magnetic ring 4 is embedded within the body 2 of the grinding wheel.
Le figure 1 e 2 illustrano una prima forma di realizzazione della mola, in cui l'anello diamantato 5 ha una forma sostanzialmente a "L". Le figure 3 e 4 illustrano una seconda forma di realizzazione della mola, in cui l'anello diamantato 5 Ã ̈ di tipo periferico, destinato ad essere appoggiato al corpo 2 della mola. Figures 1 and 2 illustrate a first embodiment of the grinding wheel, in which the diamond ring 5 has a substantially "L" shape. Figures 3 and 4 illustrate a second embodiment of the grinding wheel, in which the diamond ring 5 is of the peripheral type, intended to rest on the body 2 of the grinding wheel.
Il montaggio della mola in entrambe le forme realizzative avviene serrando una volta sola il corpo 2 della mola al mandrino 7 e poi accoppiando al corpo della mola l'anello diamantato 5, mediante accoppiamento magnetico con 'anello magnetico 4. The assembly of the grinding wheel in both embodiments takes place by tightening the body 2 of the grinding wheel only once to the spindle 7 and then coupling the diamond ring 5 to the body of the grinding wheel, by means of magnetic coupling with the magnetic ring 4.
Si à ̈ in pratica constatato come la mola superabrasiva secondo il presente trovato assolva pienamente il compito nonché gli scopi prefissati, in quanto permette un accoppiamento tra il corpo della mola e l'anello diamantato senza l'ausilio di utensili, con la necessità di un semplice cacciavite unicamente per lo smontaggio dell'anello diamantato . In practice it has been found that the superabrasive wheel according to the present invention fully achieves the intended aim and objects, since it allows a coupling between the body of the wheel and the diamond ring without the aid of tools, with the need for a simple screwdriver only for disassembling the diamond ring.
Inoltre, l'accoppiamento tra l'anello diamantato e il corpo della mola ha una garanzia di durata nel tempo in virtù della sostanziale immutabilità dell'azione magnetica esercitata dall'anello magnetico annegato entro il corpo della mola . Furthermore, the coupling between the diamond ring and the body of the wheel has a guarantee of duration over time by virtue of the substantial immutability of the magnetic action exerted by the magnetic ring embedded within the body of the wheel.
La mola superabrasiva così concepita à ̈ suscettibile di numerose modifiche e varianti, tutte rientranti nell'ambito delle allegate rivendicazioni; inoltre, tutti i dettagli potranno essere sostituiti da altri elementi tecnicamente equivalenti . The superabrasive wheel thus conceived is susceptible of numerous modifications and variations, all of which fall within the scope of the attached claims; moreover, all the details can be replaced by other technically equivalent elements.
In pratica, i materiali impiegati, nonché le dimensioni e le forme contingenti, potranno essere qualsiasi a seconda delle esigenze e dello stato della tecnica. In practice, the materials used, as well as the contingent shapes and dimensions, may be any according to requirements and to the state of the art.
