A working head for a hydraulic power tool including a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head configured to receive a first moveable die comprising a first body length. A second die head is adapted to receive a second die comprising a second body length. The first body length of the moveable die is different from the second body length of the stationary die.

A method for disassembling a pipe joint is provided. A radially expandable sleeve positioned on a shaft is inserted into a distal open end of a pipe of the pipe joint. A sleeve nut on a threaded portion of the shaft is tightened against the sleeve to urge the sleeve to longitudinally slide along a tapered distal end of the shaft in a distal direction. The sleeve radially expands as the sleeve slides in the distal direction along the tapered distal end of the shaft. The sleeve is radially expanded until an interference fit is formed between the sleeve and the pipe. A force is then exerted upon the shaft to urge the shaft in a proximal direction and remove the pipe from a pipe fitting of the pipe joint.

The present invention relates to a pipe joint locking tool. According to one example of the present invention, provided is a pipe joint locking tool which fixes and couples a pipe joint including a connection member and a tightening member to a conduit, the pipe joint locking tool being characterized by comprising: a first lever and a second lever, which rotate about a lever hinge shaft; and a pair of tightening chucks coupled to the upper ends of the first and second levers, the pair of tightening chucks being provided with pipe joint supporting portions on which the connection member and the tightening member are respectively placed and supported, and tightening and coupling the pipe joint to the conduit by moving the tightening member toward the connection member according to the operation of the first and second levers, wherein the pair of tightening chucks having the pipe joint supporting portions of a size matching the size of the pipe joint are selected from a group having pipe joint supporting portions of different sizes, and are coupled to the upper ends of the first and second levers so as to be replaceable.

Portable, hand-held hydraulic tools having a modular power unit within a handle assembly and a working head assembly mated to the handle assembly. The working head assembly can have a pair of movable jaws or a movable jaw and a fixed jaw. The jaws can be configured to perform different operating operations, such as crimping operations and cutting operations.

Systems and methods for reporting usage of a power tool. The power tool comprises a pair of jaws configured to crimp a workpiece, a piston cylinder configured to actuate at least one of the pair of jaws, and a sensor configured to sense operating characteristics associated with a crimping application. An electronic processor connected to the sensor. The electronic processor is configured to receive, from the sensor, one or more characteristic signals, determine, based on the one or more characteristic signals, a first operating characteristic of the power tool, and determine, based on the one or more characteristic signals, a second operating characteristic of the power tool. The electronic processor is configured to determine the crimping application of the power tool based on the first operating characteristic and the second operating characteristic and generate a report indicating the crimping application performed by the power tool.

A swage tool includes a power unit connected to a yoke. The power unit exerts vertical force on a die block. The yoke holds swage dies in place and opposes the force exerted by the die block. The die block transfers the load exerted by the power unit into the swage dies, which surround the connector. The swage dies convert vertical force from the power unit into a radial swage on the connector. Quick release endplates hold the swage dies in place in the yoke and the die block. A yoke shroud keeps broken pieces of the yoke together if the yoke fails. A counter records the number of swages made by the tool. A rotating handle, a stand, remote wireless actuation and swage die identification imprints are also provided.

A tube coupling apparatus includes first and second clamping jaws that are mounted on a tool body. The clamping jaws are movable relative to each other between an open configuration in which they are receive a compressible tube connector, and a closed configuration in which they apply a compression force to compress the compressible tube coupling about one or more tube members. An actuator is arranged to move at least one of the clamping jaws to the closed configuration and a controller is operative to control the actuator. A sensor is provided that is arranged to determine a system parameter indicative of the compression force applied to the coupling by the clamping jaws and to progressively increase the compression force of the clamping jaws during a fitting operation. The controller monitors the system parameter data from the sensor and automatically controls the actuator to prevent the compression force exceeding a predetermined threshold based on the sensor data.

A tool and method of operating the tool is provided. The tool includes a first jaw, the first jaw arranged to rotate about a first pivot. A second jaw is arranged adjacent the first jaw, the second jaw arranged to rotate about a second pivot. A first cam member is rotatable about an axis, the first cam member being operably coupled to second jaw. A second cam member is rotatable about the axis, the second cam member being operable coupled to the first jaw. At least one movable handle is operably coupled to the first cam member and the second cam member. A clutch is operably coupled to the first cam member and the second cam member, the clutch being configured to allow free-rotation in first direction about the axis and prevent rotation in an opposite second direction.
