Description

DESCRIZIONE DESCRIPTION

L_a presente invenzione riguarda una macchina sagomatrice di super fici di catene particolarmente di metallo prezioso. E' noto ch? attua),niente 1' operazione di diamantatura viene eseguita mediante macchine che asportano omogeneamente? mediante un utensile diamantato? una certa sezione superficiale del prodotto da lavorare. Il risultato di tale operazione e' in genere una superficie lucida e piana. La presente invenzione consente invece di ottenere delle super fici lavorate composte di varie sfacettature inclinate tra di loro ottenendo cosi' una rifrazione multipla della luce. Inoltre si possono ottenere superfici bombate? incavate? ondulate, zigrinate e altre varie. The present invention relates to a machine for shaping surfaces of chains particularly of precious metal. It is known ch? actua), nothing The diamond cutting operation is carried out by means of machines which remove homogeneously? using a diamond tool? a certain surface section of the product to be processed. The result of this operation is generally a shiny and flat surface. The present invention, on the other hand, allows to obtain machined surfaces composed of various facets inclined to each other, thus obtaining a multiple refraction of light. Furthermore, can rounded surfaces be obtained? hollowed out? wavy, knurled and other miscellaneous.

Detto scopo e? raggiunto mediante il dispositivo illustrato a titolo indicativo e non limitativo nelle unite tavole 1. e 2 in c ui: Said purpose and? achieved by means of the device illustrated for indicative and non-limiting purposes in the joined tables 1 and 2 in which:

La TAVOLA 1 e' un prospetto in parte sezionato della vista anteriore della macchina. TABLE 1 is a partially sectioned elevation of the front view of the machine.

La TAVOLA 2 e? un dettaglio in cui si vede l 'applicazione dei motori che danno il moviritento alla catena. TABLE 2 and? a detail in which we see the application of the motors that give movement to the chain.

Con riferimento alla TAVOLA 1 e' raffigurato il dispositivo nel quale una catena continua di metallo prezioso 1 avanza nella direzione delle frecce su di essa indicate 2. La catena viene svolta dalla bobina di partenza 3 tramite una coppia di cinghie in contrasto tra di loro 4-5 la quale coppia avra' moto da uno dei due motori di trascinamento ? il quale determina la velocita' di avanzamento della catena. La catena viene poi avvolta dalla puleggia rotante 7 Cche e' la camma di guida; sulla quale viene lavorata dall?utensile 8 montato sul motore 9 orientabile in qualsiasi posizione tramite il braccio a snodi 10 in tal modo che il piano descritto dal percor?so della punta del diamante possa formare qualsiasi angolo con l?asse della puleggia rotante che e? la guida della catena 7. With reference to TABLE 1, the device is shown in which a continuous chain of precious metal 1 advances in the direction of the arrows indicated on it 2. The chain is unwound from the starting reel 3 by means of a pair of belts in contrast with each other 4 -5 which torque will have motion from one of the two drive motors? which determines the speed of advancement of the chain. The chain is then wound by the rotating pulley 7 which is the guide cam; on which it is machined by the tool 8 mounted on the motor 9 which can be oriented in any position by means of the articulated arm 10 in such a way that the plane described by the path of the diamond tip can form any angle with the axis of the rotating pulley which is ? the chain guide 7.

Da qui passa alla seconda coppia di cinghie di traino guidate ciascuna da tre puleggie :L1 che girano nel senso indicato dalle frecce come vedesi da tav. 1. From here it passes to the second pair of towing belts, each guided by three pulleys: L1 which rotate in the direction indicated by the arrows as seen in pl. 1.

Quest?ultima coppia di cinghie? montate sulla piastra 13 simmetrica alla 14? facendo perno sull'albero del motore 12 hanno la possibilit?' di oscillare continuamente dal sensore 15 al sensore 1?. This latest pair of straps? mounted on plate 13 symmetrical to 14? by pivoting on the shaft of the motor 12 have the possibility? to continuously oscillate from sensor 15 to sensor 1 ?.

Tali sensori elettrici comandano tramite l'azionamento motore 12 di aumentare o diminuire i giri della puleggia motrice 1.7 collegata all'albero del motore stesso. These electric sensors control by means of the motor drive 12 to increase or decrease the revolutions of the driving pulley 1.7 connected to the shaft of the motor itself.

La tensione costante della catena necessaria sulla zona di lavoro e? prodotta dal peso 18 collegata col cordino 13 alla piastra 13. The constant chain tension required on the work area is? produced by weight 18 connected with lanyard 13 to plate 13.

Il senso di avanzamento della catena pu?? essere invertito invertendo le seguenti funzioni: dei sensori 15?16 con quelle dei sensori 20-21; della puleggia 17 con quella della puleggia 2 del peso 1S con il peso delle viti di battuta 24 con quelle delle viti di bloccaggio 25? invertendo il senso di rotazione dei due motori 16 e 6. The direction of advancement of the chain can? be inverted by inverting the following functions: of the sensors 15? 16 with those of the sensors 20-21; of the pulley 17 with that of the pulley 2 of the weight 1S with the weight of the stop screws 24 with those of the locking screws 25? reversing the direction of rotation of the two motors 16 and 6.
