del BREVETTO PER MODELLO INDUSTRIALE DI of the PATENT FOR THE INDUSTRIAL MODEL OF
UTILIT?? UTILITY
avente per titolo: having as title:
?PRESSA RADIALE PER LA RACCORDATURA DI RADIAL PRESS FOR THE FITTING OF
TUBI FLESSIBILI OLEODINAMICI? HYDRAULIC FLEXIBLE HOSES?
Il presente modello di utilit? riguarda una pressa radiale per la raccordatura di tubi flessibili. This utility model? concerns a radial press for joining flexible pipes.
Gi? sono note presse radiali per la deformazione e la lavorazione di particolari aventi superfici esterne circolari o poligonali, in particolare per la raccordatura di tubi flessibili. Tali presse hanno usualmente due blocchi, o gioghi, che si muovono radialmente l?uno verso l?altro azionati da relativi organi di comando, provocando ravvicinamento/allontanamento di una serie di superfici ortogonali tra loro ricavate in detti blocchi e la conseguente apertura/chiusura di una serie di ganasce poste e guidate tra dette superfici. In particolare, nel Brevetto EP 0 S39 789 ? descritta una pressa radiale in cui: Gi? radial presses are known for deforming and machining parts having circular or polygonal external surfaces, in particular for joining flexible pipes. These presses usually have two blocks, or yokes, which move radially towards each other, activated by relative control members, causing a series of orthogonal surfaces obtained in said blocks to be brought closer / removed and the consequent opening / closing. of a series of jaws placed and guided between said surfaces. In particular, in the Patent EP 0 S39 789? described a radial press in which:
- un blocco (mobile) ? guidato di fronte all?altro blocco (fisso) mediante dei tiranti; - a (mobile) block? guided in front of the other (fixed) block by means of tie rods;
- i tiranti sono paralleli alla direzione del movimento del blocco mobile, penetrano il blocco fisso esternamente e da lati opposti rispetto alle superfici ortogonali di supporto delle ganasce, e sono saldamente collegati al blocco mobile; - the tie rods are parallel to the direction of movement of the mobile block, penetrate the fixed block externally and from opposite sides with respect to the orthogonal support surfaces of the jaws, and are firmly connected to the mobile block;
- oltre il blocco fisso, i tiranti sono collegati ad un comando di trazione, dove ad ogni tirante ? assegnato un proprio comando idraulico; e in cui - beyond the fixed block, the tie rods are connected to a traction control, where to each tie rod? assigned its own hydraulic control; and in which
- i comandi idraulici sono realizzati con un diametro del pistone e del cilindro tale da avere la distanza minima possibile al di sotto dell?asse della pressa ortogonale al piano delle ganasce. - the hydraulic controls are made with a piston and cylinder diameter such as to have the minimum possible distance below the axis of the press orthogonal to the plane of the jaws.
Scopo del presente trovato ? comunque quello di fornire una pressa radiale del tipo succitato, avente per? un comando di trazione di nuova configurazione, particolarmente adatto a fornire un?elevata stabilit? e solidit? alla struttura della pressa, e che consenta elevate forze di compressione con una ridotta potenza motrice del comando idraulico. Purpose of the present invention? however, that of providing a radial press of the aforementioned type, having for? a newly configured traction control, particularly suitable for providing high stability and solidity? to the structure of the press, and which allows high compression forces with a reduced drive power of the hydraulic control.
Lo scopo ? conseguito, in accordo con il trovato, con una pressa radiale secondo la rivendicazione 1 che seguir?. The purpose? obtained, in accordance with the invention, with a radial press according to claim 1 which will follow.
I dettagli del trovato saranno qui di seguito descritti con riferimento all?allegato disegno, indicativo e non limitativo, nel quale l?unica figura mostra la pressa in sezione parziale. The details of the invention will be described below with reference to the attached drawing, indicative and not limiting, in which the only figure shows the press in partial section.
La pressa radiale in esame ? costituita da un blocco inferiore fisso 10 posto su una piattaforma 11 che chiude superiormente un telaio 12, ed un blocco superiore 13 posto sopra e di fronte al blocco inferiore 10 e traslabile verticalmente rispetto a questo. The radial press under consideration? consisting of a fixed lower block 10 placed on a platform 11 which closes a frame 12 at the top, and an upper block 13 placed above and in front of the lower block 10 and vertically translatable with respect to it.
Sui loro lati prospicienti, i due blocchi 10, 13 presentano ognuno una coppia di superfici 14, 1 S inclinate e ortogonali tra loro, separate da una superficie orizzontale 16. Gli assi di simmetria delle superfici 14, 15 e 16 si intersecano nell?asse orizzontale A della pressa. In modo noto, su dette superfici 14-16 appoggiano quattro corpi esterni 17, portanti ognuno una ganascia 18 e aventi superfici laterali 17? destinate a loro volta a supportare e guidare altri corpi interni 19 muniti anch?essi di rispettive ganasce 18. I corpi 17 e 19 sono disposti e configurati in modo tale che le superfici delle ganasce rivolte verso l?asse A risultano equidistanti da esso. La traslazione del blocco superiore 13 verso quello inferiore 10 provoca l?awicinamento radiale alla stessa velocit? dei corpi 17 e 19 e quindi di tutte le ganasce 18. On their facing sides, the two blocks 10, 13 each have a pair of surfaces 14, 1 S inclined and orthogonal to each other, separated by a horizontal surface 16. The symmetry axes of the surfaces 14, 15 and 16 intersect in the axis. horizontal A of the press. In a known way, on said surfaces 14-16 rest four external bodies 17, each carrying a jaw 18 and having lateral surfaces 17? in turn designed to support and guide other internal bodies 19 also provided with respective jaws 18. The bodies 17 and 19 are arranged and configured in such a way that the surfaces of the jaws facing the axis A are equidistant from it. The translation of the upper block 13 towards the lower one 10 causes the radial approach at the same speed. of bodies 17 and 19 and therefore of all jaws 18.
Il blocco superiore 13 ? mosso da mezzi di comando idraulici 20 posti all?interno del telaio 12, al di sotto della piattaforma 11, ed ? guidato sul blocco inferiore 10 per mezzo di una coppia di colonne 21. Tali colonne sono saldamente fissate superiormente al blocco superiore 13 con dadi 22, attraversano il blocco inferiore 10 esternamente e da Iati opposti rispetto alle superfici 14 e 15 ed entrano nel telaio 12 attraverso la piattaforma 11 per fissarsi inferiormente ai mezzi di comando idraulici 20. The upper block 13? moved by hydraulic control means 20 placed inside the frame 12, below the platform 11, and? guided on the lower block 10 by means of a pair of columns 21. These columns are firmly fixed above the upper block 13 with nuts 22, they pass through the lower block 10 externally and from opposite sides with respect to the surfaces 14 and 15 and enter the frame 12 through the platform 11 to be fixed below the hydraulic control means 20.
Tali mezzi di comando 20 comprendono un organo di trazione 23 per la chiusura in pressione della pressa attorno al pezzo da lavorare ed un cilindro 24 di avvicinamento/allontanamento rapidi del blocco superiore 13 rispetto al blocco inferiore 10. In accordo con il trovato, l?organo di trazione 23 consiste in un unico cilindro previsto per alloggiare un pistone di trazione 25 a cui sono vincolate, in posizioni opposte rispetto al suo centro, le due colonne 21. In altri termini, tali colonne costituiscono gli steli di un unico pistone 25. Said control means 20 comprise a traction member 23 for closing the press under pressure around the workpiece and a cylinder 24 for rapid approach / removal of the upper block 13 with respect to the lower block 10. According to the invention, traction member 23 consists of a single cylinder designed to house a traction piston 25 to which the two columns 21 are constrained, in opposite positions with respect to its center. In other words, these columns constitute the rods of a single piston 25.
Le colonne di guida 21, inoltre, sono fissate, ad esempio mediante viti, ad una trave di rinforzo 26, affacciata inferiormente al pistone 25, detta trave essendo a sua volta solidale al cilindro 24 di avvicinamento/allontanamento rapidi. Tale cilindro 24 ha un pistone 27 vincolato, attraverso il relativo stelo 27?, al blocco inferiore 10 in modo tale che, immettendo olio in pressione nella camera del cilindro 24, si provoca lo spostamento rapido di questo, e quindi della trave di rinforzo 26, delle colonne di guida 21 e del blocco superiore 13, rispetto al pistone 27 e quindi rispetto al blocco inferiore 10 (v. linea a tratti in figura). Vantaggiosamente, il pistone di trazione 25 presenta centralmente un anello di riduzione 28, il quale permette di ridurre sensibilmente la sezione di spinta del pistone, consentendo quindi l?utilizzo di una pompa a bassa portata. Tra l?organo di trazione 23, con relativo pistone 25 e anello di riduzione 28, e la piattaforma 11 ? inoltre interposto un fondello 29, attraversato dalle colonne di guida 21 e dallo stelo 27? del cilindro 24, detto fondello 29 contrapponendosi al blocco inferiore 10 durante la fase di pressatura, evitandone la deformazione. The guide columns 21 are also fixed, for example by means of screws, to a reinforcing beam 26, facing underneath the piston 25, said beam being in turn integral with the rapid approach / removal cylinder 24. This cylinder 24 has a piston 27 constrained, by means of the relative rod 27?, To the lower block 10 in such a way that, by introducing pressurized oil into the chamber of the cylinder 24, it causes the rapid displacement of this, and therefore of the reinforcement beam 26. , of the guide columns 21 and of the upper block 13, with respect to the piston 27 and therefore with respect to the lower block 10 (see broken line in the figure). Advantageously, the traction piston 25 has a central reduction ring 28, which allows to significantly reduce the thrust section of the piston, thus allowing the use of a low-flow pump. Between the traction member 23, with its piston 25 and reduction ring 28, and the platform 11? furthermore interposed a bottom 29, crossed by the guide columns 21 and by the stem 27? of the cylinder 24, said bottom 29 opposing the lower block 10 during the pressing step, avoiding its deformation.
La pressa, infine, ? completata da un gruppo motore 30 di azionamento di una pompa 31 destinata all?alimentazione dei mezzi di comando idraulici 20. Grazie alla compattezza dei blocchi 10, 13 della pressa e dei mezzi di comando 20 stessi, gruppo motore 30 e pompa 31 possono essere vantaggiosamente alloggiati internamente al telaio 12 della pressa, protetti e sicuri da manovre non autorizzate. Finally, the press? completed by a motor unit 30 for driving a pump 31 intended to feed the hydraulic control means 20. Thanks to the compactness of the blocks 10, 13 of the press and of the control means 20 themselves, the motor unit 30 and pump 31 can be advantageously housed inside the frame 12 of the press, protected and safe from unauthorized maneuvers.
Il funzionamento dettagliato della pressa ? di per s? noto e non necessita qui di un?ulteriore descrizione. Da sottolineare il fatto che il fissaggio delle due colonne di guida su di un unico pistone rende la struttura della pressa particolarmente stabile e solida, in quanto consente di evitare disassamenti tra le due colonne e conseguenti deformazioni dei due blocchi. A ci? va inoltre aggiunto l?effetto reattivo del fondello 29 nei confronti delle forze di compressione agenti sul blocco inferiore 10 e sulla piattaforma 11. The detailed operation of the press? by itself? known and does not need a further description here. It should be emphasized that the fixing of the two guide columns on a single piston makes the structure of the press particularly stable and solid, as it allows to avoid misalignments between the two columns and consequent deformations of the two blocks. To there? the reactive effect of the bottom 29 against the compression forces acting on the lower block 10 and on the platform 11 must also be added.
