The present invention relates to a sheet-metal bending machine. It comprises a fixed support structure (1) bearing a lower pressing element (3) on which the sheet (4) to be bent is placed and to which lower pressing element (3) a mobile upper pressing element (5) is associated; the machine also comprises a mobile frame (9) bearing a lower blade (11) and an upper blade (10). Said blades (10) and (11) perform the bending of the sheet (4) when the mobile frame (9) is raised or lowered. The mobile frame (9) is furthermore able to slide away from and towards the said sheet (4) by means of an activating system comprising at least one cam device (14), to which a connecting element (16) with the mobile frame (9) is solidly fixed, which cam device (14) is able to rotate in both directions according to pre-established and automated operative phases. <IMAGE> |
