Definitions

  • the invention relates to a cutting and forming press with a hydro-mechanical articulated lever drive, in which the drive cylinder for the ram is carried by a guide arranged in the stator between lateral guides, via a bridge construction connected to it by threaded spindles or other height-adjustable means, and which is adjustable within the area of the free space of the frame-shaped stand
  • German patent specification DE-C-29 25 416 introduced a toggle lever sheet metal cutting press, introduced as a differential travel press, with a pressure medium cylinder drive arranged between two toggle lever systems that bend with their knee joints towards the center of the press and are symmetrical about this, the piston of which presses the end of its piston rod at the center of the press joint attacks two links, which are articulated at the other end to the toggle lever systems, the connecting joint with the help of the press ram having a guide transverse to the direction of the piston rod, the criterion of which is the support of the pressure medium cylinder drive on the press ram, whereby according to a further claim the ram is designed as a frame.

Claims (3)

1. Presse à couper et à déformer munie d'un entrainement à genouillère hydromécanique, dans laquelle le vérin (3) d'entrainement du coulisseau (2) est supporté par une structure en portique (5) intercalée, dans le bâti (1), entre des guides latéraux (12) auxquels elle est reliée par l'intermédiaire de broches filetées (4) ou autres moyens réglables en hauteur, et qui est réglable à l'intérieur de la région de l'espace libre du bâti (1) en forme de cadre, caractérisée par le fait
que la structure en portique (5) forme la liaison entre les axes de portée (6) disposés, de part et d'autre, avec orientation symétrique par rapport au centre de la presse, et reçoit un guide central (7) pour la tige de piston (3.1), y compris la délimitation de cette dernière par un premier point d'articulation (10.4), ainsi que le vérin d'entrainement (3),
que les deux axes de portée (6) forment, avec d'autres points d'articulation consécutifs (8 et 9), un triangle rigide pivotant (10) dont le point d'articulation (9), dirigé vers le centre du coulisseau (2), rejoint respectivement, par l'intermédiaire d'au moins deux pièces d'entrainement de levage (10.1 et 10.2) accouplées par un second point d'articulation (10.3), le premier point d'articulation (10.4) mobile en direction du guide central, et
que les points d'articulation (10.3) situés en aval de part et d'autre se prolongent de part et d'autre par une courbe distincte (7.1), dans la région inférieure du guide central (7), et les points d'articulation (6 et 8) du triangle (10) sont reliés au coulisseau (2) par une partie de levier prolongée (13).
2. Presse à couper et à déformer, selon la revendication 1, caractérisée par le fait
que le point d'articulation (10.3), respectivemnent guidé dans les courbes (7.1), est matérialisé par un galet rotatif
3. Presse à couper et à déformer, selon la revendication 1, caractérisée par le fait
que la démultiplication totale est conçue de telle sorte que la course du vérin d'entraînement (3) représente sensiblement le double de la course du coulisseau (2).
