Abstract

La présente invention concerne un dispositif servant à incurver des découpes de tôle en forme de segments d'anneau de cercle pour en faire des pièces coniques Ce dispositif est monté sur une machine à arrondir les tôles comprenant deux pieds 1 et 2 ainsi que des rouleaux cintreurs 3 et 4. Une butée 6 servant de guidage et d'appui à l'arête plus courte des découpes de tôle 5 transmet la pression d'application à un dispositif de contre pression 8 souple et réglable coopérant avec le commutateur de l'entraînement des rouleaux. La butée précitée est montée tournante autour d'un axe 7 sur une traverse 9 fixe, prévue entre les pieds 1 et 2 de la machine L'invention s'applique aux machines à cintrer les tôlesThe present invention relates to a device for bending sheet metal cutouts in the form of ring segments of a circle to make tapered pieces. This device is mounted on a sheet rounding machine comprising two feet 1 and 2 as well as bending rollers 3 and 4. A stop 6 serving as a guide and support for the shorter edge of the sheet metal cutouts 5 transmits the application pressure to a flexible and adjustable back pressure device 8 cooperating with the switch of the drive of the plates. rollers. The abovementioned stop is mounted to rotate around an axis 7 on a fixed cross member 9, provided between the feet 1 and 2 of the machine. The invention applies to machines for bending sheets.
