A vise provided with a movable jaw device having separated approaching and clamping steps in a bending machine die, said vise (4) having a fixed jaw portion (7) and a movable jaw device (10) comprising a body (6) having two abreast supporting walls (8, 9), on an external side of one of which an operation mechanism (20) of the movable jaw is mounted, and upper edges (31, 32) of the supporting walls acts as cams for opposite spindles (29, 30) laterally projecting from one hydraulic cylinder (28) that is swing mounted on the movable jaw (11). The upper edges (31, 32) have two respective notches (33, 34) designed to receive the projecting spindles (29, 30) in such a way that the extension of the rod (27) of the hydraulic cylinder (28), being locked in position by its projecting spindles (29, 30) in the respective notches (33, 34), keeps the movable jaw (11) in closed position. |
