Abstract

Pressa idraulica per la stampaggio a compressione di materiali plastici: la pressa comprende un piano inferiore fisso ed un piano superiore mobile lungo colonne di guida a loro volta scorrevoli rispetto al piano inferiore. Dei sensori controllano la discesa del piano mobile e l'abbassamento delle colonne di guida inviando segnali ad un'unità logica di controllo programmata per avviare il movimento di discesa delle colonne durante il movimento d'abbassamento del piano mobile e rispettivamente per bloccare il piano mobile alle colonne in movimento, quando la velocità relativa tra le parti risulta sostanzialmente zero. Si riduce in questo modo il ciclo di lavoro della pressa, con continuità di movimento del piano mobile.Hydraulic press for compression molding of plastic materials: the press includes a fixed lower surface and an upper surface movable along guide columns which in turn slide relative to the lower surface. Sensors control the descent of the moving platen and the lowering of the guide columns by sending signals to a logic control unit programmed to start the descending movement of the columns during the lowering movement of the movable platen and respectively to block the movable platen to moving columns, when the relative speed between the parts is substantially zero. This reduces the work cycle of the press, with continuity of movement of the mobile table.
