摘要： The invention relates to a riveting tool for setting blind rivet nuts and/or blind rivet screws, comprising a drive piston which is able to be hydraulically adjusted from an initial position toward an end position, a pull rod which is releasably and operatively connected to the drive piston and which is able to be adjusted by the drive piston from a rivet receiving position into a setting position and a coupling element fixing the pull rod and a drawing mandrel to one another in the longitudinal axial direction. In order to provide a riveting tool of the type mentioned above by which uniform setting processes of rivets may be carried out with a high degree of repeated accuracy, it is provided that the riveting tool for fixing the setting position has an adjusting unit with a stroke-limiting element which is axially adjustable relative to the coupling element in the longitudinal axial direction of the pull rod, said stroke-limiting element being in engagement with the coupling element via a stop surface in the setting position.

摘要： A fastener installation tool includes a nose assembly, first and second cylinders, first and second pistons, and a yoke. The nose assembly is adapted to apply an axial load to a fastener along a longitudinal axis of the nose assembly. The first and second cylinders are diametrically opposed to one another with respect to the longitudinal axis of the nose assembly. The first piston is disposed within the first cylinder and is movable along a longitudinal axis thereof. The second piston is disposed within the second cylinder and is movable along a longitudinal axis thereof. The yoke connects the first piston, the second piston, and the nose assembly such that motion of one of the pistons along its corresponding longitudinal axis causes motion of the other one of the pistons along its corresponding longitudinal axis and motion of at least a portion of the nose assembly along its longitudinal axis.

摘要： The invention relates firstly to a method of operating a hydraulic pressing unit (1), wherein a motion part (7) is moved into a pressing position by the build-up of a hydraulic pressure which results from the filling of a hydraulic space (6) with hydraulic medium from a supply space (5), wherein furthermore the motion part (7) is designed to move back automatically from the pressing position into an end position under the effect of a return spring (15), and the non-return valve (16) is designed to close only after the pressure drops below a certain pressure acting on the non-return valve (16) due to the hydraulic medium running back, and furthermore to such a hydraulic pressing unit (1). In order to specify a method which enables the motion part to be optionally stopped in a position, it is proposed that, in order to have an effect on the hydraulic medium upstream of the non-return valve (16), said hydraulic medium flowing when the latter is open, means (25) are provided which counteract the flow of the hydraulic medium in such a way that a pressure drop which occurs leads to the displacement of the non-return valve (16) into the closed position. In concrete terms, an improvement from the manipulation point of view is achieved in that means (25) are provided which act on the flow of the hydraulic medium in the sense of a pressure drop in such a way that the non-return valve (16) moves into the closed position.

摘要： A method and apparatus for forming rivet joints with a desired amount of clearance to allow pivotal motion of the parts interconnected by such joints. Parts to be riveted together are aligned with each other, and a rivet is placed into aligned holes. A parts clamp urges the parts and a preformed head of the rivet against a rivet support anvil to establish an initial condition. A parts support anvil is placed in a required position with respect to the rivet support anvil prior to formation of the second head on the opposite end of the rivet, to provide the desired amount of clearance. The parts support anvil is moved by pushing against a set of arched leaf springs to adjust their effective length, using a hydraulic motor controlled in response to an electrical signal from a transducer that measures movement of parts by the parts support anvil.

摘要： The fastener installation apparatus and method of the present invention include a housing and a moveable body at least partially within the housing. The moveable body defines a plurality of openings and is fixably attached to at least one piston, which is in moveable contact with the housing. First and second cavities are defined on opposite sides of the piston and respective openings in the moveable body are in communication with opposite sides of the piston. In addition, a valve directs a fluid through the appropriate openings in the moveable body and into the first cavity or the second cavity, as desired, which, in turn, alternately extends and retracts the moveable body relative to the housing. A jaw extends from the housing in alignment with the moveable body, such that the jaw and the moveable body cooperate to install a fastener upon extension of the moveable body.
