Title (EN) A CONTROL ELEMENT ADAPTED TO PREVENT AN EXTERNAL-FLANGE ANGLE IRON FROM BEING TWISTED DURING ITS BENDING
(FR) ELEMENT DE COMMANDE CONÇU POUR EMPECHER UNE CORNIERE A AILE EXTERIEURE DE SE TORDRE PENDANT SON PLIAGE
Abstract: front page image
(EN)A control element (1) adapted to prevent an external-flange angle iron from being twisted during its bending is applied to a variable-radius bending machine, on which an angle iron (10) is worked by deformation by means of at least two couples of lower co-axial rollers (7, 8, 7', 8') and at least a third upper roller (9), the one flange (11) of the angle iron (10) being clamped by the lower rollers (7, 8, 7', 8'), and the other flange (12) facing outward. The control element (1) comprises a frustoconical head (2) pivoted on a stem (3) designed to be received into a co-axial housing hole that is frontally performed on the support element (13) of a cylindrical control roller (14), having three degrees of freedom, of the bending machine.
(FR)L'invention concerne un élément de commande (1) conçu pour empêcher une cornière à aile extérieure de se tordre pendant son pliage. Cet élément est utilisé dans une plieuse à rayon variable sur laquelle une cornière (10) est travaillée par déformation au moyen d'au moins deux paires de rouleaux coaxiaux inférieurs (7, 8, 7', 8') et d'au moins un troisième rouleau supérieur (9), une des ailes (11) de la cornière (10) étant serrée par les rouleaux inférieurs (7, 8, 7', 8') et l'autre aile (12) étant dirigée vers l'extérieur. L'élément de commande (1) comprend une tête tronconique (2) pivotant sur une tige (3), cette dernière étant conçue pour venir se loger dans un trou coaxial ménagé sur la face de l'élément de support (13) d'un rouleau de commande cylindrique (14) de la plieuse, ce rouleau de commande présentant trois degrés de liberté.
