The invention concerns a digitally controlled machine for bending, forming, folding or coiling a bar, said machine comprising in standard manner a frame, a rotary bending tool to produce bends in different planes, wherein a bar is moved along an unwinding axis and brought through a bending shank borne by the frame then through the bending tool (3) whereof the digital axial movement, perpendicular to the unwinding axis is transmitted from a motor (5) by means of a lathe (2). The invention is characterised in that: the bending tool (3) is borne by a standard conical tool support (1); and the lathe is combined with means automatically unclamping the jaws (6) of the pliers when the lathe reaches the end of its digital axial stroke away from the bending station, and automatically clamping said jaws when the lathe begins its digital axial movement in the opposite direction, bringing it closer to the bending station.
L'invention concerne une machine à commande numérique pour le cambrage, le
formage, le pliage ou le cintrage d'une barre, machine comportant
classiquement un bâti, un outil de cintrage tournant pour pouvoir obtenir des
plis dans différents plans, machine dans laquelle une barre est déplacée selon
un axe de défilement et amenée à travers un nez de pliage porté par le bâti
puis à travers l'outil de pliage (3) dont le mouvement numérique axial,
perpendiculairement à l'axe de défilement est transmis depuis un moteur (5) au
moyen d'une tournette (2), caractérisé en ce que: d'une part l'outil de pliage
(3) est porté par un support d'outil conique standard (1); d'autre part en ce
que la tournette est combinée à des moyens automatiques de desserrage des mors
(6) de la pince lorsque la tournette arrive en fin de course de son mouvement
numérique axial dans le sens de l'éloignement du poste de pliage, et de
serrage automatique desdits mors lorsque la tournette débute le mouvement
numérique axial en sens inverse, dans le sens du rapprochement du poste de
pliage.
