Abstract: The invention relates to a device (1) for securing a tool (2), in particular a bending tool, comprising a receiving. space (4) for receiving an engaging part (5) of the tool and means (9) arranged in or close to the receiving space for locating and/or communicating with the tool. The device is further provided with a first protective layer (11) at least partially separating the locating and/or communication means from the receiving space. The tool can comprise a locating and/or communication element (14) which co-acts with the locating and/or communication means and which is closed off from the surrounding area by a second protective layer (15). The invention further relates to a method for manufacturing such a securing device.

Abstract: 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. The compensating elements each can be pressed stepwise to a position compensating the detected deviations during the deforming operation. Piezoelectric actuators can be used to exert the resistance force and/or to move the compensating elements.

Abstract: Disclosed is a clamping device for clamping a tool, which includes a part receiving the tool, an actuated member and an engaging member to be brought into contact with the tool. The clamping device is further provided with a transmission placed between the actuated member and the engaging member. The actuated member can be pneumatically or electrically driven, and includes for instance a pneumatic jack, an electric motor or a piezoelectric element or an electromagnet. The actuated member can also be hydraulically driven. The transmission can include a wedge-shaped member or a lever. The clamping device can be self-braking.
