Abstract
In un attrezzatura idroelastica per l'imbutitura di sagomati di lamiera a) è prevista una piastra (8) del cuscino per imbutitura con sistema di attivazione multipunto corrispondentemente alla geometria di stampaggio del pezzo (7) da lavorare ed all'interno della piastra (8) del cuscino per imbutitura a ciascun punto-traguardo (20), corrispondentemente al settore del reticolo rispettivamente dima di foratura (18) avente le misure "a" e "b" è associato un pistone idraulico (23) a corsa corta con spine per imbutitura (13) su di esso calzabili, laddove la corsa del pistone a corsa corta (23) ammonta come massimo solamente a 10 mm,b) a ciascun pistone a corsa corta (23) sono rispettivamente associati un cilindro a corsa corta (35) con settori idraulici di azione dinamica (21 o 22) abbinabili in modo arbitrario corrispondentemente al pezzo (7) in lavorazione oppure alla piastra (12) del premilamiera.c) la piastra (8) del cuscino per imbutitura, in corrispondenza dei quattro angoli esterni, è sostenuta idraulicamente con rispettivamente un sistema (3; 14) differenziale a cilindro-pistone regolato per posizioni e movimenti paralleli e d) mediante adeguato comando dell'apparecchiatura di regolazione multipunto della posizione del sistema (3; 14) differenziale a cilindro-pistone, le forze eccentriche, al variare del baricentro dinamico dei settori (21; 22) di azione delle forze, vengono assorbite idraulicamente in modo automatico.(Fig. 1).In a hydroelastic equipment for deep drawing sheet metal a) there is a plate (8) of the deep drawing cushion with a multipoint activation system corresponding to the molding geometry of the piece (7) to be worked and inside the plate (8 ) of the drawing cushion at each point-finish (20), corresponding to the sector of the reticle, respectively drilling template (18) having the sizes "a" and "b" is associated with a short stroke hydraulic piston (23) with pins for deep drawing (13) which can be fitted on it, where the stroke of the short stroke piston (23) amounts to a maximum of only 10 mm, b) each short stroke piston (23) is respectively associated with a short stroke cylinder (35) with hydraulic sectors of dynamic action (21 or 22) that can be arbitrarily matched corresponding to the piece (7) being processed or to the plate holder plate (12). c) the plate (8) of the deep-drawing cushion, at the four external corners , it is hydraulically supported with a system (3; 14) cylinder-piston differential adjusted for parallel positions and movements and d) by means of an adequate control of the multi-point adjustment device of the system position (3; 14) cylinder-piston differential, the eccentric forces, when the dynamic center of gravity of the sectors changes (21; 22) of action of the forces, are absorbed hydraulically automatically (Fig. 1).
