The invention concerns a bending tool (6) with an actuating element (19) accessible outside the tool receptacle, with coupled to it a locking element (20) with a locking catch (21) for securing the bending tool (6) in the tool receptacle. The first end portion (32) of the actuating element (19) has an actuating face (33) arranged on the end side and the second end portion (34) of the actuating element (19) has an actuating recess (35).

The invention further concerns a gripping device (14) for manipulating a bending tool (6), comprising a first gripping arm (59) and a second gripping arm (60) displaceable relative to the first gripping arm (59) in the clamping direction (64), said gripping arms (59) being formed to engage in a gripping groove (23, 24) of the bending tool (6) and to clamp the bending tool (6). Also formed is an unlocking member (65) for actuating an actuating element (19) of the bending tool (6), said unlocking member (65) being longitudinally displaceable normally to the clamping direction (64) relative to the gripping arms (59, 60).

A flat routing material includes a flat conductive material and an insulating coating covering the conductive material. The routing material includes a bent portion as a part bending in an edgewise direction at a predetermined angle or more, and one or more folds extending toward the outer peripheral side of the bent portion are provided on at least the inner peripheral side of the bent portion. The folds are manufactured by press working.

The invention relates to a device for changing bending tools (15, 16) in a bending machine (2) for bending metal sheets, in particular in a press brake, comprising at least one tool magazine (6) for storing the bending tools (15, 16), which, when positioned in a working area of the bending machine (2), cause the metal sheets to bend. The at least one tool magazine (6) is arranged on a frame (3) which is configured to be positioned in a free-standing manner without a mechanical connection to the bending machine (2) in an operating position of the device (1), wherein the at least one tool magazine (6) can be moved from a first position out of the frame (3) into a second position, in which at least a part of the tool magazine (6) that can be moved out lies in a contact-free manner within the bending machine (2).

A press brake system that utilizes a punch holder adapted to be used with punch chips of various radii to achieve the desired bend on a part. The system maintains a common shut height enabling the press brake operator to be able to put different radius tip punches next to each other in a single press brake tooling setup.

The invention relates to a bending press (1) and/or feeding device (2) for feeding a bending press (1) with bending tools (5, 6), comprising: at least one tool holder (3, 4; 13, 14) with a rail (7) comprising an inner profile (8) for receiving and displacing a bending tool (5, 6); and at least one transfer device (15) which can be driven by a drive (21) for displacing a bending tool (5, 6) inside the tool holder (3, 4; 13, 14) and/or between the tool holder (13, 14) of the feeding device (2) and a tool holder (3, 4) of a bending press (1), and the transfer device (15) comprises a releasable coupling (18) for connecting a bending tool (5, 6), said transfer device (15) being guided in the rail (7) of the tool holder (3, 4; 13, 14) and the active area of the coupling (18) is arranged at least partially inside the rail (7).

The invention relates to a method for compensating deviations in a deforming operation between two beams of a press, comprising of arranging one or more compensating element at a suitably chosen location in the press, detecting the deviations and moving the compensating element(s) relative to the beams by (electro) mechanical means during the deforming operation such that the detected deviations are compensated. The compensating elements can be moved here to an over-compensating position prior to the deforming operation and pressed out of their over-compensating position during the operation by the load on the beam, wherein each compensating element exerts an adjustable resistance force on surrounding parts of the press. It is conversely possible for the compensating elements each to be pressed stepwise to a position compensating the detected deviations during the deforming operation. It is possible to use (piezoelectric) actuators to exert the resistance force and/or to move the compensating elements. The invention further relates to a device with which this compensation method can be performed.

A locking device for locking tools in a press brake includes a first jaw (2) and a second jaw (3), movable towards and away from each other, and at least one safety hook (4) interposed there between provided with a retaining tooth (41) adapted to be inserted into a groove (52) defined in the shank (51) of a tool (5), wherein on an inner side (35) of the second jaw (3) facing the first jaw (2) there is provided at least one thrust surface (36) adapted to cooperate with, while resting slidingly against, at least one corresponding rest surface (43) on an outer side (42) of the safety hook, the thrust surface (36) and the rest surface (43) lying substantially parallel along a thrust plane (P) sloping in the opposite direction to the first jaw (2) by an angle (α) of between 30° and 60° with respect to a vertical plane.
