摘要： A hydraulic pressing unit includes a hydraulic pump, supply and hydraulic chambers, moving and stationary parts, a restoring spring, and a return valve provided within or attached to a housing. The moving part is displaced from a starting position into a pressing position as a result of filling the hydraulic chamber with a hydraulic medium from the supply chamber by using the hydraulic pump. The return valve is automatically displaced into an open position as a result of a hydraulic pressure corresponding to the pressing position, and the restoring spring moves the moving part. A piston acts on the flow of the hydraulic medium and lowers the pressure such that the return valve is displaced into the closed position.

摘要： In a torque-switched clutch between an input shaft and an output shaft, the clutch transferring into a release position from a positive-locking connection when a limiting torque is reached, at least one positive-locking element is connected to one of the shafts. The positive-locking element interacts with a positive-locking receiver of the other shaft. The positive-locking element is movable against a force out of a coupling position into a release position in a non-destructive manner. The positive-locking element is of latch type design and is mounted on the one shaft so as to be pivotable relative to that shaft for movement between a latch locking position and a latch overrun position.

摘要： A device is used to sever an electrical power cable for the transmission of high voltage. The device includes a frame having first movable cutting blade carried thereon and second stationary cutting blades carried thereon. The blades can sever the electrical power cable upon movement of the first cutting blade relative to the frame. A sensor is provided and is configured to register a position of the first cutting blade relative to the frame. An evaluation and/or transmission controller is configured to receive information from the sensor and interrupt severing of the electrical power cable by the blades in response to the information.

摘要： A hydraulically operated handheld device and a method of operating same are provided. The device includes a hydraulic pump, a moving part, a fixed part and a return valve with an associated valve seat. The moving part is moved into a working position due to the buildup of a hydraulic pressure by filling a hydraulic chamber with hydraulic medium from a reservoir with the aid of the hydraulic pump. The moving part can be automatically moved back from the working position into an end position upon reaching a predefined working pressure by opening the return valve. The hydraulic pressure acting upon the return valve is increased by a separately triggerable pressure increase, which results in opening of the return valve, in a hydraulic medium volume located upstream of the return valve in a flow direction of the hydraulic medium during the movement into the end position.

摘要： The invention relates to a method for producing a nut which is rotationally connected to a flat part connecting section of a cable shoe, wherein the flat part connecting section has a passage opening, the nut has a sitting face which is at the bottom in the connected state, and a holder section extends on the nut from the sitting face further downward, wherein a tapered portion of the passage opening is formed by a holder material section which is preliminarily curved into the passage opening by deformation, and the holder material section is produced by a recess which is made in the flat part connecting section so as to surround the passage opening on a top side of the flat part connection section, which top side is associated with the sitting face. In order to specify a method of this kind which can be carried out in respect of production, in particular in respect of the production costs, in a favourable manner, it is proposed that the holder material section is first formed and the nut is placed onto the top side, wherein the holder section protrudes downward beyond a narrowest cross section of the passage opening which is formed by the holder material section, and that the holder section is then widened below the narrowest cross section, for the purpose of holding the nut on the cable shoe in a rotatable and interlocking manner. The invention further relates to a nut which is fitted in a rotatable manner on a flat part connecting section of a cable shoe.

摘要： A method for operating a hydraulically operated hand-held device is provided. The hand-held device includes a hydraulic pump, a moving part, a fixed part and a return valve with an associated valve seat. The moving part can be displaced into a working position by a build-up of hydraulic pressure produced by filling a hydraulic chamber with hydraulic medium from a storage chamber using the hydraulic pump. The moving part can be automatically moved back from the working position into an end position by opening the return valve, if a predetermined working pressure is reached. The hydraulic pressure acting upon the return valve for triggering a movement of the moving part into the end position is increased independently of reaching the predefined working pressure.

摘要： A handheld hydraulically actuatable crimping device includes a hydraulic piston that can be displaced in a cylinder against the force of a spring. The piston is connected to a crimping part by a piston rod in order to carry out a crimping operation. The piston includes first and second partial pistons with first and second partial application faces which can be acted upon with hydraulic medium that has the same hydraulic pressure. Both partial pistons are respectively connected to a first and a second crimping part. The second crimping part can at a greater traveling distance only be acted upon with the second partial piston. The second crimping part can be acted upon with both partial pistons over a first partial traveling distance that is defined by the displacement of the first partial piston from its initial position up to the point, at which it reaches a stop. The first crimping part is axially covered in its entirety by the second crimping part.
