A hydraulic power tool includes a housing defining a cylinder, a piston at least partially positioned within the cylinder and movable between a retracted position and an extended position, a clevis supporting a head of the power tool, a nut coupled to an outer peripheral surface of the clevis, and a collar coupled to the housing and surrounding the nut to axially constrain the nut between the collar and the housing while permitting relative rotation between the collar and the nut.

Hydraulic power tool

An example shearing head includes a first member and a second member being rotatable about a pin. The first member has a shearing surface forming a substantially right angle with a first lateral surface of the first member. The second member has a shearing surface forming a substantially right angle with a second lateral surface of the second member. The second member includes a first distal surface and a second distal surface forming a substantially right angle. The first distal surface and the second distal surface are substantially perpendicular to the second lateral surface. The second member includes a third lateral surface opposing the second lateral surface and a retainer is attached to the second member. A first surface of the retainer contacts the first distal surface, a second surface of the retainer contacts the second distal surface, and the third lateral surface contacts a third surface of the retainer.

Hydraulic tool

Embodiments of the invention provide a ram guide for a crimping tool. The crimping tool includes a crimping head and a ram head. The ram guide includes a track and slot. The ram guide is configured to guide the ram head within a crimp portion of the crimping head to axially align the ram head with the crimping head.

Ram guide for a crimper

An example hydraulic tool includes: a fluid reservoir; a pump; an electric motor; a cylinder; a piston; a first trigger button; a second trigger button; and a controller configured to perform operations comprising: receiving a first signal when the first trigger button is triggered, responsively, causing the electric motor to rotate in a first rotational direction, thereby: (i) causing the pump to provide fluid to the cylinder, and (ii) causing the piston to move in a first linear direction, thereafter, receiving a second signal when the second trigger button is triggered, and responsively to the second signal, causing the electric motor to rotate in a second rotational direction opposite the first rotational direction, thereby: (i) opening a fluid path from the cylinder to the fluid reservoir, and (ii) causing the piston to move in a second linear direction opposite the first linear direction.

A tool head includes a first frame having first and second arms extending from a base to a distal end. The tool head may also include a first blade in the frame between the first and second arms. The first blade is movable from the base toward the distal end. The tool head includes a second frame hingedly coupled to the first arm. The second frame may include a second blade. The second frame is configured to rotate between a closed-frame position and an open-frame position. The tool head includes a trip lever hingedly coupled to the first arm and configured to rotate between an open-lever position and a closed-lever position.

Tool head

A hydraulic tool includes a tool head and a moveable piston coupled to the tool head. The hydraulic tool head includes a plurality of jaws, which are operable to open and close for performing work on a workpiece. The hydraulic tool also includes a motor operable to drive the moveable piston to close the plurality of jaws to a closed position at which the work on the workpiece is completed. The hydraulic tool further includes a position sensor configured to detect when the plurality of jaws are at the closed position and responsively generate a sensor signal indicating that the plurality of jaws are at the closed position. Additionally, the hydraulic tool includes a controller configured to receive the sensor signal from the position sensor. The controller is configured to operate the motor based on the sensor signal that the controller receives from the position sensor.

Power tool

Embodiments of the invention provide a crimper for use in a tool. The crimper can include a clevis, a nest, and an indenter. The clevis can include a first leg having a first slot and a second leg having a second slot. The first leg and the second leg can extend from a cylindrical body that has a base surface. The indenter can be configured to be moved from a retracted position to an extended position. The indenter can include a body with a work surface and a base on opposing sides of the body. The base of the indenter can be configured to engage the base surface of the cylindrical body when the indenter is in the retracted position.

Dieless utility crimper

A cutting head for a power tool. The cutting head includes a first jaw having a first blade mounting surface and a second jaw having a second blade mounting surface. The second jaw is rotatably coupled to the first jaw. The cutting head also includes a first blade removably coupled to the first blade mounting surface of the first jaw and a second blade removably coupled to the second blade mounting surface of the second jaw. A first cutting edge of the first blade is substantially co-planar with a second cutting edge of the second blade. During a cutting action, the first jaw and the second jaw rotate with respect to one another to bring the first cutting edge closer to the second cutting edge.

Rebar cutting tool

An example tool includes a housing; an inclined handle coupled to, and extending obliquely from, a top portion of the housing, where the inclined handle has a first trigger button and a second trigger button; and an interlocking mechanism disposed in the inclined handle. The interlocking mechanism is configured to disable one of the first trigger button or the second trigger button while the other of the first trigger button or the second trigger button is triggered.

Tool having an inclined handle

A hydraulic power tool includes a housing defining a cylinder, a piston at least partially positioned within the cylinder and movable between a retracted position and an extended position, a reservoir containing hydraulic fluid, a pump for transferring hydraulic fluid in the reservoir to the cylinder, causing the piston to move from the retracted position toward the extended position, a return valve defining a rotational axis and positioned between the cylinder and the reservoir, and a valve actuator driven by the pump for opening the return valve, thereby fluidly communicating the cylinder and the reservoir, in response to a predetermined pressure being reached in the cylinder.
