DESCRIZIONE DESCRIPTION
" Procedimento per realizzare strumenti in materiale plastico di misura per disegnare e strumento ottenuto con il procedimento " "Procedure for making measuring instruments in plastic material for drawing and instrument obtained with the procedure"
La presente invenzione concerne un procedimento per realizzare strumenti in materiale plastico di misura per disegnare ed uno strumento ottenuto con il procedimento. The present invention relates to a process for making measuring instruments in plastic material for drawing and an instrument obtained with the process.
Sono noti strumenti di misura per disegnare quali stecche, squadre, goniometri, realizzati in materiale plastico termoiniettato, i bordi dei quali sono provvisti di scale graduate. Measuring instruments are known for drawing such as sticks, squares, protractors, made of thermo-injected plastic material, the edges of which are provided with graduated scales.
Un primo metodo di realizzazione della scala graduata consiste nello stampare per iniezione termoplastica lo strumento di misura e successivamente nello stampare con inchiostro i numeri ed i vari tratti di suddivisione. A first method of producing the graduated scale consists in molding the measuring instrument by thermoplastic injection and subsequently in printing the numbers and the various subdivision sections with ink.
Tale metodo presenta tuttavia l'inconveniente che con il tempo l'inchiostro si deteriora facendo perdere allo strumento il suo uso di precisione. However, this method has the drawback that over time the ink deteriorates, making the instrument lose its use of precision.
Un altro metodo consiste nell'effettuare lungo i bordi, con un punzone metallico a caldo, delle incisioni corrispondenti ai numeri e tratti di suddivisione previa interposizione di un nastro a trasferimento termico fra il punzone e lo strumento di misura. Another method consists in making incisions along the edges, with a hot metal punch, corresponding to the numbers and subdivision sections after interposition of a thermal transfer ribbon between the punch and the measuring instrument.
Tale metodo presenta tuttavia altri inconvenienti ed in particolare: However, this method has other drawbacks and in particular:
- un'imprecisione del segno a causa del deterioramento del punzone con il passare del tempo, - an imprecision of the mark due to the deterioration of the punch with the passage of time,
- la necessità di avere tanti punzoni quanti sono i diversi tipi di tratteggiatura o numerazione e per le diverse misure di stecche e squadre es. 30cm, 15 cm 30cm, - the need to have as many punches as there are different types of hatching or numbering and for the different measures of slats and squares eg. 30cm, 15cm 30cm,
- l'impossibilità di ottenere una scala graduata di elevata affidabilità sempre dovuta al deterioramento del punzone. - the impossibility of obtaining a highly reliable graduated scale, again due to the deterioration of the punch.
Scopo dell'invenzione è di eliminare tali inconvenienti e di realizzare uno strumento di misura per disegnare che presenti una scala graduata che mantenga con il tempo le sue caratteristiche di affidabilità. The object of the invention is to eliminate these drawbacks and to provide a measuring instrument for drawing which has a graduated scale which maintains its reliability characteristics over time.
Altro scopo dell'invenzione è di realizzare uno strumento di misura che presenti un'elevata precisione. Another object of the invention is to realize a measuring instrument which has a high precision.
Tali scopi sono raggiunti secondo l'invenzione con un procedimento per realizzare strumenti in materiale plastico di misura per disegnare come descritto nella rivendicazione 1. These objects are achieved according to the invention with a method for making measuring instruments in plastic material for drawing as described in claim 1.
La presente invenzione viene qui di seguito ulteriormente chiarita in una sua preferita forma di pratica realizzazione, riportata a scopo puramente esemplificativo e non limitativo, con riferimento all'allegata tavola di disegni, raffigurante in modo schematico il procedimento per ottenere strumenti di misura per disegnare secondo l'invenzione. The present invention is further clarified hereinafter in a preferred embodiment thereof, reported for purely illustrative and non-limiting purposes, with reference to the attached drawing table, schematically depicting the process for obtaining measuring instruments for drawing according to the invention.
Come si vede dalla figura il procedimento secondo l'invenzione prevede una fase iniziale di termoiniezione in una pressa 2 di un materiale plastico per ottenere un manufatto 4 per disegnare quale una stecca, una squadra, un goniometro. As can be seen from the figure, the process according to the invention provides for an initial step of thermo-injection in a press 2 of a plastic material to obtain an article 4 for drawing such as a stick, a square, a protractor.
Successivamente il manufatto viene trattato con una sorgente laser 6, controllata da un microprocessore 8, che tramite il fascio luminoso 10 da essa emanato, realizza delle cavità 12 già ben visibili ed utilizzabili sui bordi dello strumento corrispondenti ai numeri ed alle tacche di suddivisione per ottenere lo strumento 14 di misura per disegnare. Subsequently, the product is treated with a laser source 6, controlled by a microprocessor 8, which, by means of the light beam 10 emanating from it, creates cavities 12 which are already clearly visible and usable on the edges of the instrument corresponding to the numbers and subdivision notches to obtain the measuring tool 14 for drawing.
Da quanto detto risulta chiaramente che il procedimento secondo l'invenzione presenta numerosi vantaggi ed in particolare: From what has been said it is clear that the process according to the invention has numerous advantages and in particular:
- un'elevata precisione data dalla maggior sottigliezza del segno ottenuto con il raggio laser, - high precision given by the greater subtlety of the mark obtained with the laser beam,
- un'elevata riproducibilità delle caratteristiche, - a high reproducibility of the characteristics,
- una versatilità di realizzazione dei numeri e/o tacche ottenute per programmazione della sorgente laser, - a versatility of realization of the numbers and / or notches obtained by programming the laser source,
- la possibilità di marchiare lo strumento di misura con i dati del cliente con altissima versatilità. - the possibility of marking the measuring instrument with the customer's data with very high versatility.
In una variante realizzativa il procedimento secondo l'invenzione prevede di realizzare lo strumento di disegno con un fascio laser di diverso tipo che provoca variazione permanente di colore sul materiale plastico del manufatto. In a variant embodiment, the method according to the invention provides for the creation of the drawing instrument with a laser beam of a different type which causes permanent color variation on the plastic material of the product.
La presente invenzione è stata illustrata e descritta in una sua preferita forma di pratica realizzazione, ma si intende che varianti esecutive potranno ad essa in pratica apportarsi senza peraltro uscire daN'ambito di protezione del presente brevetto per invenzione industriale. The present invention has been illustrated and described in a preferred embodiment thereof, but it is understood that executive variations may in practice be applied to it without however departing from the scope of protection of the present patent for industrial invention.
