Claims (2)

  1. Dispositif pour le pliage d'une tôle (4), comportant un bâti de machine, une barre inférieure (1), une barre supérieure (2) et une barre de pliage (3), la tôle (4) étant serrée entre les barres inférieure et supérieure (1, 2), et une partie de tôle dépassant de ces barres (1, 2) étant pliée selon un angle de pliage prédéterminé au moyen de la barre de pliage (3), laquelle agit sur cette partie de tôle et peut être pivotée autour d'un axe de pivotement (S), la barre de pliage (3) pouvant simultanément, pendant son pivotement, être déplacée dans une première direction de translation (A), perpendiculaire à son axe de pivotement (S), l'axe de pivotement (S) étant fixe, et la barre de pliage (3) étant réalisée de telle sorte que sa distance à l'axe de pivotement (S) augmente pendant le processus de pliage, de sorte que la barre de pliage (3) peut être guidée continûment le long d'un contour de pliage prédéterminé, caractérisé en ce que la barre de pliage (3) peut en outre, pendant son pivotement, être déplacée dans une seconde direction de translation (B), qui s'étend sensiblement perpendiculairement au plan contenant la première direction de translation (A) et l'axe de pivotement (S), et en ce que le dispositif est pourvu d'un moyen de contrôle contrôlant la barre de pliage pendant le cours de pliage de telle sorte que la course de glissement entre barre de pliage et tôle est pratiquement réduit à zéro et un roulement de la barre de pliage sur le côté inférieur de la tôle est obtenu.
  2. Dispositif selon la revendication 1, caractérisé en ce que la barre de pliage (3) est guidée de manière sensiblement rectiligne, sur ses deux côtés frontaux, dans un guide respectif (18) s'étendant perpendiculairement à l'axe de pivotement (S), et ce guide (18) est agencé sur une première bielle oscillante (14), montée sur le bâti de machine (11) avec possibilité de pivotement autour de l'axe de pivotement (S), et en ce que le guide (18) de la barre de pliage (3) est agencé sur une seconde bielle oscillante (16), qui est elle-même montée avec possibilité de déplacement sur la première bielle oscillante (14).
