  • Patent number: 10404025
    Abstract: An arrangement for electrically conductively connecting a cup shaped copper contact part to an electrical conductor that is made of a plurality of individual wires containing aluminum. The arrangement has a cup-shaped contact part, which includes a bottom and a cylindrical sleeve integrally connected to and projecting away from the bottom with tight contact of the sleeve to the conductor. The cup-shaped contact part is configured to be pushed onto the conductor until the end face of the conductor rests against the bottom of the contact part. At least one rotating tool is configured to be removably placed with sustained pressure, subsequently to the cup-shaped contact part, until the material of the conductor is softened due to the increased temperature of the material of the conductor due to friction to such an extent that it integrally connects to the contact part.

  • Patent number: 10029347
    Abstract: Pneumatic machining device includes a fixing plate, a hollow piston shell, a piston group, a machining tool, a first sealing group, and a second sealing group. The piston shell is fixed to the fixing plate and coupled to a first external pressure source and second external pressure source to feed gas into the piston shell to drive the piston group and the machining tool, respectively. The piston group and the first and second sealing groups are received inside the piston shell. The piston group is driven by the first external pressure source to move away from the fixing plate. The first and second sealing groups divide the piston shell into a number of chambers for controlling a gas pressure. The machining tool is coupled to the piston group and extends out of the piston shell to machine a workpiece as the piston group moves away from the fixing plate.

  • Patent number: 9797256
    Abstract: To provide a turbine rotor which enables mass production with a low-cost apparatus and which capable of suppressing leaning of the rotor shaft after welding to improve the yield, while a turbine blade rotor 12 and the rotor shaft 14 are fit to each other with concave and convex portions 12a and 14a and are permitted to be rotated, laser beam L from a laser beam generating device 30 is applied to a joint face 16 along the circumferential direction to weld the welding portion. Then, laser beam L is polarized to temper a region X on the rotor shaft side containing the welding portion with laser beam L. In contrast to residual stress R1 having a local angular distribution generated during the welding, residual stress R2 is permitted to be generated over the entire circumference by tempering. Leaning of the rotor shaft 14 after cooling is thereby be suppressed.

  • Patent number: 9033205
    Abstract: A method for friction stir welding is provided. The method may include determining the temperature of one or both parts being welded. The parts may then be heated to a desired temperature and then friction stir welded together. By preheating the parts, the friction required to plasticize the parts during welding may be reduced. Thereby, the rotational speed of the friction stir welding tool may be reduced, and thus the tool life may be extended without decreasing the rate at which welds are created. Additionally, the cooling rate of the weld may be regulated with a thermal control device.

  • Publication number: 20110206523
    Abstract: A process of fabricating a rotating component and a rotating component formed thereby. The rotating component has a rotational axis, at least one rim member, at least one disk member, and at least one airfoil member. The rim and disk members are welded together to define a first solid-state weld joint lying in a first plane that is not parallel to the rotational axis of the rotating component. The airfoil member is welded to the rim member to define a second solid-state weld joint lying in a second plane that is not parallel to the rotational axis of the rotating component. The rim member is located in a radially outward direction from the disk member, and the airfoil member is located in a radially outward direction from the rim member.

  • Publication number: 20110194940
    Abstract: A process of fabricating a rotating component and components formed thereby. The process includes fabricating preforms corresponding to portions of the component. Each preform has an interface surface at which the preforms can be joined to locate a first of the portions in a radially outward direction from a second of the portions. The preforms are then inertia welded together to form a profile having a solid-state weld joint containing a finer-grained material than other portions of the profile. The profile is then forged with dies to produce a forging. At least one of the dies has a recess into which the finer-grained material from the weld joint is expelled during forging to purge a joint region of the forging between the forging portions of the finer-grained material. The joint region contains grains distorted in an axial direction of the forging.

  • Patent number: 7988032
    Abstract: Two tubular components (10, 14) are provided with integral end caps (11, 15). The end caps (11, 15) are placed in abutting relationship and are held together under pressure whilst the tubular component (10) is rotated. A pressure is applied and this causes frictional heating. A friction welded joint (18) occurs at the interface between the two end caps (11, 15). On completion of the welding process a machining tool is then passed through the internal bore (12 or 16) in either of the tubular components. The machining tool cuts through the joined end caps (11, 15) to produce a single uniform bore thorough the joined components. In a further post processing operation the extruded flash (20) is removed from the outer surfaces (13, 17).
