Title (EN) PRESS HAVING A DOUBLE-ACTING HYDRAULIC CYLINDER
(FR) PRESSE COMPRENANT UN CYLINDRE HYDRAULIQUE À DOUBLE EFFET
(DE) PRESSE MIT DOPPELTWIRKENDEM HYDRAULIKZYLINDER
Abstract:
(EN) The invention relates to a press (1) or automatic punch having a drive (6), which drives a plunger (10) in an oscillating manner via an eccentric shaft (5) and via at least one connecting rod (9), wherein the at least one connecting rod (9) is rotatably mounted on the eccentric shaft (5) at one end (30), and is connected to the plunger (10) at the other end (17). According to the invention, a double-acting hydraulic cylinder (27), which can be driven in a vibratory manner, is arranged in the connecting rod (9). The invention further relates to a method for operating a press (1).
(FR) L'objet de l'invention est une presse (1) ou une machine d'estampage comprenant un entraînement (6) qui entraîne en oscillation un poussoir (10) par l'intermédiaire d'un arbre à excentrique (5) et d'au moins une bielle (9), la ou les bielles (9) étant montées en rotation au niveau d'une extrémité (30) sur l'arbre à excentrique (5) et étant reliées au poussoir (10) par l'autre extrémité (17). Selon l'invention, un cylindre hydraulique (27) à double effet, qui peut fonctionner en vibrant, est agencé dans la bielle (9). L'objet de l'invention concerne également un procédé pour faire fonctionner une presse (1).
(DE) Den Gegenstand dieser Erfindung bildet eine Presse (1) oder ein Stanzautomat mit einem Antrieb (6 ), der über eine Exzenterwelle (5) und zumindest ein Pleuel (9) einen Stößel (10) oszillierend antreibt, wobei das zumindest eine Pleuel (9) an einem Ende (30) drehbar auf der Exzenterwelle (5) gelagert ist und am anderen Ende (17) mit dem Stößel (10) verbunden ist. Erfindungsgemäß ist im Pleuel (9) ein doppeltwirkender hydraulischer Zylinder (27) angeordnet, der vibrierend betrieben werden kann. Den Gegenstand dieser Erfindung bildet auch ein Verfahren, zum Betreiben einer Presse (1).
