| 摘要 |
The invention relates to a press table (3) or press beam (4) for a press brake (1), comprising a beam element (17) having an elongate support surface (18) for attaching a bending tool (19) or tool adapter, a support beam element (24) having approximately the same length (39) as the beam element (17), connecting elements (26) with which connecting points (25) on the beam element (17) are connected, with respect to the length thereof (39), in particular symmetrically to the support beam element (24), at least one actuator (30) which acts between mutually facing pressure surfaces (28, 29) on the beam element (17) and on the support beam element (24) and which can exert an adjusting force (32) that runs approximately in the pressing direction (31) of the press brake (1) and as a result the support surface (18) of the beam element (17) is actively adjustable between a planar profile and a convex profile. In this case, the actuator (30) comprises a hose arrangement (33) which is arranged between the mutually facing pressure surfaces (28, 29), rests against the latter and is fillable with hydraulic fluid (34), said hose arrangement extending substantially in the longitudinal direction of the beam element (17). |
