The invention relates to a clamping system for a press brake, the clamping system comprising an elongate beam comprising a receiving space for receiving a part of a bending tool, a clamping element, the clamping element being movable between a first position, in which it may engage on the bending tool for clamping it in the receiving space, and a second position for releasing the bending tool, and an actuating member for displacing the clamping element, the actuating member being movable between an active position, in which it urges the clamping element towards the first position, and an inactive position in which it allows the clamping element to move to the second position. The clamping system is characterized by a first biasing member acting on the actuating member for biasing the actuating member towards its inactive position. The invention also relates to a press brake comprising such a clamping system.

The invention relates to a clamping system for a press brake, the clamping system comprising an elongate beam comprising a receiving space for receiving a part of a bending tool, a clamping element, the clamping element being movable between a first position, in which it may engage on the bending tool for clamping it in the receiving space, and a second position for releasing the bending tool. The clamping system further comprises a pressure chamber fillable with a fluid, and an actuating member for driving the engaging element in accordance with a pressure of the fluid in the pressure chamber. The pressure chamber or a cavity housing the pressure chamber is integrally formed in the elongate beam. The invention also relates to a press brake comprising such a clamping system.

The subject of the invention is a tool gripping device for gripping a bending tool with a robot, the cylindrical enclosure of which is secured to the base plate and equipped with a compressed air connection, while a cylinder head equipped with a compressed air connection is secured to the end of the enclosure opposite the base plate. A clamping element movable with compressed air is arranged in the enclosure, with the conical end of the clamping element extending out of the enclosure through the aperture of the cylinder head. A gripper is led through the hole drilled through the clamping element, the clamp shank of which is secured to the base plate, with a support head fixed eccentrically to the end of the grip stem extending out of the clamping element.

A tool holder for locating and seating varieties of differing tools. The tool holder is usable with press brake tools as well as tools for other industrial machines and equipment. The tool holder includes a clamp and a supporting body. The clamp is an assembly and, via collective operation of its components, functions with the supporting body to locate and seat tools of a variety of differing styles, sizes, and geometries.

A clamping system for a press brake includes an elongate beam having a receiving space for receiving a part of a bending tool and a clamping element. The clamping element is movable between a first position, in which it may engage on the bending tool for clamping it in the receiving space, and a second position for releasing the bending tool. The system includes an actuating member for displacing the clamping element, the actuating member being movable between an active position in which it urges the clamping element towards the first position, and an inactive position in which it allows the clamping element to move to the second position. The clamping system includes a first biasing member acting on the actuating member for biasing the actuating member towards its inactive position. A press brake including such a clamping system.

The clamping system includes a pressure chamber fillable with a fluid, and an actuating member for driving the engaging element in accordance with a pressure of the fluid in the pressure chamber. The pressure chamber or a cavity housing the pressure chamber is integrally formed in the elongate beam. A press brake comprising such a clamping system.

A tool holder assembly, as well as activation system used therewith. In some cases, the tool holder assembly is configured to shift as needed to engage tooling when the assembly is activated. For instance, the assembly has an activation system that is in fluid communication with one or more fingers via an intermediary.

A clamping system for a press brake includes an elongate beam having a receiving space for receiving a part of a bending tool. The elongate beam has at least two cavities formed therein, where each of the at least two cavities has an opening to the exterior of the elongate beam. The at least two cavities are interconnected internally. A press brake includes such a clamping system. A method of manufacturing an elongate beam for such a clamping system includes a step of providing a fluid connection to each of at least two cavities in the elongate beam by interconnecting the at least two cavities by machine from inside at least one of the at least two cavities.
