DESCRIZIONE DESCRIPTION
L'invenzione riguarda un comando per il movimento di trasporto e di ritorno dalle rotaie delle pinze di dispositivi di trasporto a due o tre assi in presse progressive. The invention relates to a control for the transport and return movement of the gripper rails of two or three axis transport devices in progressive presses.
Nei noti comandi di rotaie di pinze (costruzione propria) sono presenti, per azionare il movimento di trasporto e quello di ritorno, una traversa di trascinamento montata in guide. In questa traversa di trascina mento sono montate due slitte mobili trasversalmente al senso di trasporto, che presentano perni di guida verticali, in cui sono supportate in modo re golabile in altezza le rotaie delle pinze. In the known gripper rail drives (own construction) there is a trailing cross member mounted in guides to actuate the transport and return movements. Mounted in this driving cross member are two slides which are movable transversely to the direction of transport, which have vertical guide pins, in which the rails of the grippers are supported in an adjustable manner in height.
Le slitte con i perni di guida verticali vengono trascinate dalle rotaie delle pinze nel movimento di chiusura e di apertura. The slides with vertical guide pins are pulled by the gripper rails in the closing and opening movement.
Poich? nel movimento di chiusura e di apertura si hanno maggiori accelerazioni, la massa di queste slitte influisce svantaggiosamen te sul comportamento a flessione delle rotaie delle pinze. Devono essere presenti anche guide a rotolamento prive di gioco affinch? le rotaie delle pinze scorrano senza oscillare. Since? in the closing and opening movement there are greater accelerations, the mass of these slides has a disadvantageous influence on the bending behavior of the gripper rails. There must also be rolling guides free of play so that? the gripper rails slide without wobbling.
La presente invenzione intende realizzare a questo punto una semplificazione, per cui , in un comando eseguito come descritto in precedenza, si propone di fissare sulle due leve di comando una traversa, sul cui lato inferiore sono disposte due slitte guidate in guide e spostabili mediante aste filettate ed azionamenti, sulle cui estremit? agiscono aste di spinta montate in giunti sferici, le quali sull'altra loro estremit? sono collegate, d? nuovo tramite giunti sferici, con le rotaie delle pinze. The present invention intends to achieve a simplification at this point, whereby, in a command carried out as described above, it is proposed to fix a crosspiece on the two control levers, on the lower side of which there are two slides guided in guides and movable by means of rods. threaded and drives, on whose ends? they act push rods mounted in ball joints, which on their other end? are connected, d? new via ball joints, with the rails of the calipers.
Nella realizzazione del comando secondo la presente invenzione la traversa di trascinamento non ? supportata in guide longitudinali, bens? ? fissata sulle due leve d 'azionamento. In questa traversa di trascinamento sono supportate due slitte e tramite comandi elettrici ad aste filettate sono spostabili o regolabili in direzione d'apertura ed in quella di chiusura delle rotaie delle pinze. In the realization of the control according to the present invention, the trailing cross member does not? supported in longitudinal guides, but? ? fixed on the two operating levers. Two slides are supported in this dragging crosspiece and by means of electric commands with threaded rods they can be moved or adjusted in the opening direction and in the closing direction of the gripper rails.
Le rotaie delle pinze sono collegate, mediante aste di spinta montate in giunti sferici, con le slitte. Nel movimento di apertura e di chiusura ed in quello di sollevamento ed abbassamento le aste di spinta e seguono un movimento di pendolamento. Affinch? questo movimento di pendola mento rimanga simmetrico durante la regolazione dello scartamento tra le rotaie delle pinze, le slitte vengono spostate nelle traversa di trascina mento della stessa entit? mediante i comandi elettrici. The rails of the grippers are connected, by means of push rods mounted in ball joints, with the slides. In the opening and closing movement and in the lifting and lowering movement, the push rods follow an oscillating movement. So that? this oscillating movement remains symmetrical during the adjustment of the gauge between the rails of the grippers, the slides are moved in the trailing beam of the same amount. by means of the electrical controls.
L'invenzione viene dettagliatamente spiegata in base al disegno che rappresenta un esempio di realizzazione a piacere. Nel disegno; The invention is explained in detail on the basis of the drawing which represents an example of embodiment at will. In the drawing;
la figura 1 mostra una sezione secondo la linea A-B di figura 3; la figura 2 mostra una vista in direzione E della figura 1 ; la figura 3 mostra una sezione secondo la linea C-D della figura 1 . Figure 1 shows a section along the line A-B of Figure 3; Figure 2 shows a view in direction E of Figure 1; Figure 3 shows a section along the line C-D of Figure 1.
La figura 1 mostra una sezione del lato sinistro di una pressa progressiva con una tavola 1 della pressa, con la tavola scorrevole 2, con lo spintore 3 della pressa, il montante sinistro 4 della pressa e con la scatola di chiusura 5 con la guida 6 delle rotaie delle pinze 6. Figure 1 shows a section of the left side of a progressive press with a press table 1, with the sliding table 2, with the press pusher 3, the left column 4 of the press and with the closing box 5 with the guide 6 of the gripper rails 6.
Nella guida 6 e 6a (figura 2) delle rotaie della pinza, guida che esegue un movimento d'apertura e di chiusura nonch? un movimento di sollevamento ed abbassamento, le rotaie 7 e 7a della pinza sono supportate scorrevolmente mediante i lardoni di guida 8 e 8a nel senso del traspor to ed in quello opposto. In the guide 6 and 6a (figure 2) of the rails of the gripper, the guide performs an opening and closing movement as well as? a lifting and lowering movement, the rails 7 and 7a of the gripper are supported slidingly by means of the guide gibs 8 and 8a in the direction of transport and in the opposite direction.
Sul montante sinistro 4 della pressa sono fissate due scatole degli ingranaggi 9 e 9a, in cui sono montate girevolmente le leve di comando 10 e 10a. Two gearboxes 9 and 9a are fixed to the left upright 4 of the press, in which the control levers 10 and 10a are rotatably mounted.
Il movimento oscillante delle due leve di comando 10 e 10a viene prodotto, tramite rulli 11 , dalle camme complementari 12. The oscillating movement of the two control levers 10 and 10a is produced, by means of rollers 11, by the complementary cams 12.
All'estremit? delle leve di comando 10 e lOa ? fissata una traversa 13, in cui sono montate in guide 14 e 14a due slitte 15 e 15a nel senso del movimento d 'apertura e di chiusura della rotaia della pinza. At the end? of the control levers 10 and 10a? fixed a crosspiece 13, in which two slides 15 and 15a are mounted in guides 14 and 14a in the direction of the opening and closing movement of the rail of the gripper.
Il movimento trasversale delle slitte 15 e 15 a avviene tramite aste filettate 16 e 16a mediante azionamenti quali elettromotori 17 e 17a. Le rotaie delle pinza 7 e 7a sono collegate con le slitte 15 e 15a median te aste di spinta 19 e 19a supportate in giunti sferici 18, 18a, 18b e 18C. The transversal movement of the slides 15 and 15a takes place by means of threaded rods 16 and 16a by means of drives such as electric motors 17 and 17a. The rails of the grippers 7 and 7a are connected to the slides 15 and 15a by means of push rods 19 and 19a supported in ball joints 18, 18a, 18b and 18C.
Dalle figure 2 e 3 si notano diverse posizioni delle rotaie delle pinze, cio? nella posizione 7 a 7a di massima apertura , nella posizio ne 7b e 7c di massima chiusura, nella posizione 7d e 7e di minima apertura, nella 'posizione 7f e 7g di minima chiusura nonch? in posizione sollevata 7h e 7i . From figures 2 and 3 different positions of the rails of the pincers can be seen, that is? in position 7 to 7a of maximum opening, in position 7b and 7c of maximum closing, in position 7d and 7e of minimum opening, in position 7f and 7g of minimum closing as well? in raised position 7h and 7i.
Gli sviluppi 20 vengono trasportati per il trasferimento sulle rotaie delle pinze per esempio mediante un nastro trasportatore magnetico 21 . The blanks 20 are transported for transfer onto the gripper rails, for example by means of a magnetic conveyor belt 21.
