A method for manufacturing a composite tube having at least one double-layered portion with an annular outer layer of a first alloy and an annular inner layer of a second alloy, comprising: providing a base component (301) of the second alloy, having a central through-hole and an externally threaded section (302), providing an outer component (401) of the first alloy, having an internally threaded section (402) configured to engage with the externally threaded section, forming a tubular work piece by mounting the outer component around the base component such that the internally threaded section is in engagement with the externally threaded section, hot working the work piece so that a metallic bond is formed between the threaded sections while the mechanical interlock is maintained, and so that the work piece is elongated and its outer diameter is reduced, thus forming a composite tube.

A radial compression mechanism utilizes a string wrapped around a plurality of compression dies to move the dies inward and close a central cylindrical cavity defined by the working surfaces of the dies. The string may be coupled to a string tension mechanism that enables a user to applied a desired tension to the string and thereby compress an article within the central cylindrical cavity. The compression dies may be coupled to a base and move along die-guiding slots from an open position to a closed position. A spring may be configured to force the compression dies open and provide some back-tension to the string. The string may extend around a pully on an opposing side of the compression mechanism and both ends of the string may be coupled to the string tension mechanism.

A pipe processing tool that is configured to deform the end of a pipe so that the circumferential shape of the end of the pipe generally matches the circumferential shape of an adjacent pipe end. Matching the circumferential shapes of the pipe ends is advantageous during a pipe attachment process. The pipe processing tool can include a deformation ring with a plurality of pipe deformation members. Each pipe deformation member faces radially inward and is actuatable in a radial direction toward and away from the center of the deformation ring in order to permit engagement with the pipe. Each pipe deformation member is individually and separately actuatable from the other pipe deformation members so that the circumferential shapes of the pipes can be altered by controlling suitable ones of the pipe deformation members.

A gas-charging and flanging machine (10) includes a spin-and-press flanging device (12) for flanging a workpiece (20). The spin-and-press flanging device includes a spin-and-press mechanism (123), and the spin-and-press mechanism includes a spin-and-press wheel (123a) formed with a slant position and a flat position. The slant position is used for pressing a corresponding slant-forming position of the workpiece to form a slanted face, and the flat position is used for pressing and flattening the slanted face of the workpiece. The spin-and-press wheel displaces axially under control of an external force exerted on the spin-and-press mechanism so that a working face facing the workpiece is switchable between the slant position and the flat position. Less pressure is required for the gas-charging and flanging machine to flange a workpiece, as compared to traditional flanging machines.

An assembly (10) for crimping a frame (56) of an implant (58) comprises a crimping device (20) with a base (22) and a crimping mechanism (24) that defines a crimping aperture (26). A bath (28) having a floor (30), and one or more side-walls (32) extending upward from the floor to a side-wall height defines a receptacle (18) that is shaped to receive a portion of the crimping device. The apparatus has an assembled state in which the portion of the crimping device has been received by the receptacle, the crimping device is held securely by the bath, and the aperture is below the side-wall height. Other embodiments are also described.

A plant for realizing fitted hydraulic hoses includes: a cutting station provided with a cutter configured such as to cut a hydraulic hose into a plurality of portions of hose; a storage station of a plurality of hydraulic fittings, each of which is able to be fixed to an end of a portion of hose into which the hydraulic hose is cut; a crimping station provided with a crimping press configured such as to crimp a hydraulic fitting to an end of the portion of hose; and a control and command unit operatively connected to the crimping press of the crimping station, configured for determining a blocking force of the crimping press according to an indicative parameter of the type of hydraulic hose cut in the cutting station.

The invention relates to a method for producing a drive unit device, in particular a fan device, which has at least one first modular unit (12) and at least one second modular unit (16), which concentrically accommodates at least a portion of the first modular unit (12), with the first and second modular units (12, 16) being intended to contribute mechanically to a change in torque, and the first modular unit (12) being secured in the second modular unit (16) in at least one method step (100, 110). To increase safety and reduce process costs, it is proposed that the first modular unit (12) be secured in the second modular unit (16) by means of at least one concentric pressing process step.
