A radial press is provided including a base, a hollow ring die mounted on the base rotatably relative to a press axis with an inner contour tapering in the direction of the axis and rotationally symmetrical, and a rolling element unit rotatable relative to the axis and having a pressure ring, which surrounds the axis, and a plurality of rolling elements arranged around the axis which are rotationally symmetrical. The rolling elements are supported on the pressure ring at a variable distance from the axis and can roll on the inner contour of the ring die. A rotary drive acts on the ring die or the rolling element unit and effects rotation about the axis. A feed drive also acts on the rolling element unit or the ring die and effects axial displacement of the rolling element unit and the ring die relative to each other.

A wire stripping die is configured to be coupled to a crimping tool. The stripping die includes a die body, a first ridge, and a second ridge. The die body includes a first side, a second side, and a groove extending at least partially between the first side and the second side. The groove extends along an axis. The first ridge protrudes from a surface of the groove toward the axis by a first distance. The first ridge extends along at least a portion of the perimeter of the groove and extends at least partially around the axis. The second ridge protrudes from the surface of the groove toward the axis, and the second ridge extends parallel to the axis along at least a portion of the groove.

Electrically powered crimp tools are described. Also described are methods of operating the tools and methods of crimping. The tools include a housing, an electric motor, a roller screw assembly, and a jaw assembly. In particular versions of the tools the jaw assembly includes a cam linkage member that is manually displaced by a user to more easily open the jaws after performing a crimp.

An adjustable clamp for welding together pipes, the adjustable clamp having a first axis perpendicular to the pipes and a second axis parallel to the pipes. The adjustable clamp includes four clamp corners, four transverse bolts, two parallel bolts, two threaded inserts, and four spaces. Each clamp corner includes a first transverse aperture, a second transverse aperture, and a third parallel aperture. The first and second apertures are transverse relative to the first axis and the third aperture is parallel relative to the first axis. Each transverse bolt is securable within the first and second transverse apertures of the four clamp corners. Each parallel bolt is securable within the third apertures of the four clamp corners. Each threaded insert is placeable within the third apertures of the four clamp corners and each threaded insert is mated with a respective parallel bolt. Each spacer surrounds a portion of each transverse bolt.

Methods and devices for extracting an internal pipe/tube element from a connected outer pipe/tube element. Certain embodiments are directed to methods and devices that inwardly distort a pipe/tube at a connection to allow the pipe to be more easily disconnected without damaging the overlapping (outside) half of the connection. Collapsing the pipe adjacent to, and into, the fitting and reducing its circumference allows the pipe to be unscrewed or slide out of the overlapping side of the connection. Embodiments are described including partially cutting thru the male portion of the connection and locally compressing and collapsing the pipe to radially disengage it from interior of the opposing fitting or pipe section. In one method, an interior pipe/tube is disengaged from a fitting or overlapping connection where a connection (weld, adhesive or soldered attachment) is utilized and the connection is selected small/weak enough to be broken in the compression process.

Portable, hand-held, battery operated, hydraulic tools are provided with a tool frame, a force sensor, and a location detector. A piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task, such as to apply a crimp to an electrical connector. The tool determines the maximum force applied to the crimp and records that maximum force along with the geographic location of the tool when the crimp was formed. The maximum force provides an indication of the quality of the crimp and the recorded location allows a potentially defective crimp to be located.
