Hydraulic crimp tools, working heads for hydraulic crimp tools and die sets for crimping wire connectors onto electrical conductor wires using such hydraulic crimp tools are provided. The die sets include identical dies that can be repositioned on the working head to mechanically secure wire connectors to an electrical conductor wire or a bundle of electrical conductor wires from different orientations.

To realize a method for manufacturing a hub unit bearing capable of increasing the processing efficiency of a staking portion. An axial inner end portion of a hub ring 22 is processed into a staking portion 26 by rotating a die 31 around a reference axis C in a state in which the die 31 having a rotation axis α inclined with respect to the reference axis C is pressed against the axial inner end portion of the hub ring 22 under a condition that the hub ring 22 is disposed so that a center axis of the hub ring 22 is coaxial or parallel to the reference axis C and the hub ring 22 is supported to be radially movable.

Techniques for implementing and/or operating a system that includes a pipe fitting to be secured to a pipe segment and a swage machine. The pipe fitting includes a fitting jacket to be conformally deformed around tubing of the pipe segment. The swage machine includes a grab plate that interlocks with the pipe fitting, a die plate, in which a die is to be loaded in the die plate, a swaging actuator secured to the die plate, in which the swaging actuator facilitates conformally deforming the fitting jacket around the tubing of the pipe segment by causing the die plate and the grab plate of the swage machine to move toward one another, and a die retainer actuator secured to the grab plate of the swage machine, in which the die retainer actuator extends through the grab plate toward the die plate and pushes against the die.

In a method for thickening a plastically deformable hollow body wall of a hollow body, with effective radial support of the unthickened hollow body wall on an outer supporting face of an outer mold and with effective radial support of the hollow body wall on an inner supporting face of an inner supporting body, the hollow body is acted on by a compressive force by two application members at application points by moving the application members towards one another in the axial direction with a compressing movement. The application points on the hollow body are distanced from one another in the axial direction. An expansion space of the outer mold is arranged between the application points. Due to the compressing movement of the application members, material of the hollow body wall between the application points is plasticised in the region of the expansion space of the outer mold, and plasticised material of the hollow body wall flows into the expansion space of the outer mold, thus thickening the hollow body wall.

The inspection device of the swing forging apparatus includes an inspection tool and a laser irradiation surface. When inspecting the swing forging apparatus, the inspection tool is supported to the head to which the processing roll is not supported, with a substantially same condition as the processing roll, and the inspection tool has a function of emitting a laser beam onto a central axis of the inspection tool. When inspecting the swing forging apparatus, the laser irradiation surface is arranged so that a relative position of the laser irradiation surface to the head in an axial direction of the head can be changed and the laser beam can be irradiated to the laser irradiation surface.

A method of making a medical guidewire including providing a wire having a length that includes a proximal length and a distal length. The method further includes applying cold work to the distal length and not applying cold work to the proximal length, thereby imparting to the distal length a diameter that is smaller than the proximal length diameter; and applying a reducing process to the wire whereby the proximal length is reduced to have an outer diameter that is the same as the outer diameter of the distal length. The proximal length has an inner diameter and the distal length has an inner diameter that is less than the inner diameter of the proximal length.

A swaging device includes a top die and a bottom die that can move in a vertical direction between an open position and a closed position. Each die includes an inclined surface, and the device further includes swaging elements each having a complementary inclined surface that is in contact with the inclined surface of each die, both in the open position and in the closed position. The swaging elements are arranged opposite one another such that in at least any position other than the open position, they are in contact by certain non-inclined surfaces opposite the complementary inclined surfaces.
