Tool systems for forming sealed connections are described. The tool systems include a pivoting jaw assembly and one or more insertable die sets that are received, positioned between, and engaged with the jaws of the jaw assembly. Examples of the die sets include clinch-type die sets and radial press die sets. Also described are methods of using the tool systems and die sets.

A method of assembling and retaining a noise attenuation device (30) within an air inlet (16) of a compressor cover (12) includes inserting the noise attenuation device (30) into the air inlet (16) and applying a rolling compressive force to the air inlet (16) using a forming tool (40). As a result, the air inlet terminal end (17) is deformed radially inward so as to form a radially-inwardly protruding lip (17b) about the air inlet terminal end (17). The radially-inwardly protruding lip (17b) is configured to retain the noise attenuation device (30) within the air inlet (16). The forming tool (40) used to form the radially-inwardly protruding lip (17b) is also described.

Systems and methods for identifying power tool accessories. Power tools described herein include a power tool housing including an interface. The interface is configured to receive an accessory. The accessory includes an identifier. The power also includes a motor and an electronic processor connected to the motor and a memory. The electronic processor is configured to detect insertion of the accessory into the interface and determine, when the accessory is inserted into the interface, an accessory type of the accessory based on the identifier. The electronic processor is configured to select operating parameters for the motor based on the accessory type.

Press ring, pressing tool, adapter element for a pressing tool, adapter element for a press ring, pressing device having an electric drive and a pressing tool, system having an adapter element for pressing a press fitting by means of a press ring. Here, the press ring has at least two different pairs of receiving elements for connection to a corresponding pair of connecting elements of different pressing tools. The pressing tool has at least two different pairs of connecting elements for connection to respectively one corresponding pair of receiving elements of different press rings. The adapter elements for a pressing tool and press ring each have a pair of connecting elements for connection to a corresponding pair of connecting elements of a pressing tool and a pair of connecting elements for connection to a corresponding pair of receiving elements of a press ring.

A pressing tool for plastically deforming a workpiece is described. The pressing tool includes a housing and an electric motor for actuating the pressing tool. The pressing tool also includes an instrument seat which is adapted to receive an interchangeable instrument head at the housing. The pressing tool also includes a mechanical safety element which is arranged in a manner that is movable from an open position, in which an instrument head may be inserted into the instrument seat, into a closed position, in which the instrument head is locked in the instrument seat. The pressing tool additionally includes a mechanical actuating element which may interact with the safety element in order to be able to cause the pressing tool to be enabled for a pressing process.

A method for joining composite rods with tubular shape includes internal and external collars applied to the ends of the composite rod and deformed via unidirectional compressive load applied by a clamp in the radial direction of the composite rod cross-section. The resulting plastic deformation of the metal collars and composite rod interlock those components to support both compressive and tensile loads.

A mobile pipe fusion assembly system includes a fusion machine skid comprising a flat cross-sectional area whereon a pipe fusion machine rests, a forward skid comprising a flat cross-sectional area whereon a first pipe stand rests, and a rear skid comprising a flat cross-sectional area whereon a second pipe stand rests. The fusion machine skid is coupled to the forward skid by a first coupling. The fusion machine skid is coupled to the rear skid by a second coupling. The system is configured such that when the forward skid is pulled along a length of the pipe, the forward skid pulls the fusion machine skid via the first coupling and the fusion machine skid pulls the rear skid via the second coupling.
