A working head (1) for a compression or cutting tool (100) comprises a connecting portion (3) for a removable connection of the working head (1) with an actuation part (2) of the tool (100), two jaws (4) movable between an open position and a closed position to perform the compression or cutting, and a local storage (6) configured for storing one or more cumulative data representative of a stress history of the jaws (4), wherein the local storage (6) is fixed to the working head (1).

Tools for crimping or cutting of an object such as a wire, cable, or connector. The tool includes a first member and a second member configured to come together through a gap to crimp or cut a wire, cable or connector and a laser positioned to visually indicate a region where at least one member traverses as the first and second member come together through the gap. This visual indication aids in alignment of the object for the crimping or cutting operation.

A control device according to some embodiments of the disclosure includes one or more motors directed by the control device to form whip(s) from a length of a cable by causing the cutting of the cable in accordance with specifications based at least in part on whip information. An interface communicates the whip information between the control device and a user device.

A tool is provided in order to facilitate utilization by users in a wide variety of applications. By way of example, a multipurpose tool may include first and second handles configured for relative movement between a closed position and an open position. At least the first handle includes an axle extending thereacross. The multipurpose tool also includes one or more tool members rotatably mounted upon the axle and foldable into the first handle and first and second jaws rotatably connected to the first and second handles, respectively. At least the first jaw defines an opening through which the axle of the first handle extends. The multipurpose tool further includes a resilient member disposed at least partially within the opening in order to apply a bias force to the first jaw during rotation of the first jaw relative to the first handle.

Embodiments of the invention provide a cutting tool. The cutting tool includes a pin that defines an axis, a first jaw, a second jaw, a first blade, and a second blade. The first and second jaws are configured to rotate about the axis. The first jaw includes a first ear surface that has a first ear bore that is dimensioned to receive the pin. The second jaw includes a second ear surface rotationally engaged with the first ear surface and includes a second ear bore that is dimensioned to receive the pin. The blades can include a tapered face and a non-tapered face. The first and second ear surfaces can be coplanar with the respective non-tapered face.

A tool configured to cut a workpiece includes a tool head which has a receiving contour in which the workpiece is received, and a movable cutting edge with a cutting contour. In the course of a cutting process, the cutting edge passes through the receiving contour. The cutting edge is subjected to the effect of an advancement part and can be moved to such an extent in the cutting direction(s) that it can pass all the way through the workpiece. In an embodiment, a position of the cutting edge reached after the cutting edge has passed all the way through the workpiece, the cutting edge, with removal from the advancement part, can be moved out from the cutting direction(s).

Embodiments of the invention provide a ram assembly for a hydraulic tool. The ram assembly includes a ram piston having a ram cavity. The ram piston receives a hydraulic pressure reaction force. The ram assembly further includes an overload assembly disposed in the ram cavity or in a cavity defined by a manifold. The overload assembly includes a burst disc positioned at a first end of the ram cavity or manifold, a lock nut positioned at a second end of the ram cavity or manifold, and a spacer positioned between the burst disc and the lock nut. The spacer transfers a supporting force applied to the lock nut to the burst disc. The hydraulic pressure reaction force and the supporting force both act in the same direction, and thus, are additive forces acting on the burst disk.

An example tool includes a hydraulic actuator cylinder; a piston slidably accommodated within the hydraulic actuator cylinder, where the piston includes a piston head and a piston rod extending from the piston head along a central axis direction of the hydraulic actuator cylinder, the piston head divides an inside of the hydraulic actuator cylinder into a first chamber and a second chamber, and the piston rod is disposed in the first chamber and configured to move one or more jaws of the tool; a pump configured to provide pressurized fluid; and a sequence valve configured to block the pressurized fluid from flowing into the second chamber of the hydraulic actuator cylinder until pressure of the pressurized fluid exceeds a threshold pressure value.

An electric tool (1) includes piston (36) reciprocably housed in cylinder (34) provided in main body portion (10) and be pushed by a pressure of fluid; tool head (14) coupled to a distal end of the main body portion and performing a predetermined operation by being pushed by the piston; return channel (40) communicating from the cylinder to a fluid tank to allow the fluid to flow therethrough; pressure regulating valve (44) disposed in operational flow channel (42) branching from the return channel and taking an open position when the pressure of the fluid in the return channel becomes equal to or higher than a predetermined value; operating pin (46) disposed in the operational flow channel and pushed by the pressure of the fluid flowing therein; and return valve (48) disposed in the return channel and taking an open position by being pushed by the operating pin.

An in-line portable, hand held hydraulic cutting tool having a handle assembly and a working head assembly is provided. The handle assembly has a tool frame portion and a neck portion. The working head assembly has a pair of jaw members joined so that they are movable relative to each other and held in place by a locking pin. Each jaw member has a cutting blade secured to or directly formed into the jaw member. A stabilizer can be secured to or directly formed into one or both jaw members. The one or more stabilizers are aligned with a respective cutting blade such that during a cutting operation at least an edge of the stabilizer engages an object being cut to limit rotation of the object during the cutting operation.
