Abstract
Embodiments of the disclosure provide a tool head for a hydraulic tool. The tool head includes a variety of lightweight, high-strength materials, such as titanium, titanium alloys, and carbon fibers. The tool head can be configured as a cutting, crimping, or pressing tool head.
Claims15
A working head for a hydraulic power tool, the working head comprising:
- a head frame;
- a first die holder moveable along the head frame, the first die holder adapted to receive a first die;
- a second die holder coupled to the head frame, the second die holder adapted to receive a second die;
- and
- an insert arranged along the head frame and positioned to absorb a maximum stress during a crimping action;
- at least one or more of the head frame, the first die, the second die, or the insert comprising one or more of titanium or carbon fiber.

A tool head for a hydraulic tool, the hydraulic tool including a hydraulic ram, the tool head comprising:
- a first jaw having a first jaw insert and a first wear insert, the first jaw insert arranged to engage a work piece and the first wear insert arranged to engage the hydraulic ram;
- a first bushing around which the first jaw is rotatable;
- a second jaw having a second jaw insert and a second wear insert, the second jaw insert arranged to engage the work piece and the second wear insert arranged to engage the hydraulic ram;
- and
- a second bushing around which the second jaw is rotatable;
- the first jaw and the second jaw comprising one of carbon fiber or a titanium alloy;
- the first jaw insert, the second jaw insert, the first wear insert, the second wear insert, and the first bushing comprising steel.
4 more elements
A method of forming a carbon fiber jaw head for a hydraulic tool, the method comprising:
- identifying a stress field in the jaw head, the stress field including directions of force that result in stress in the jaw head when the jaw head is used in a crimping, cutting, or pressing action;
- aligning fibers of carbon fiber in the direction of the stress field so that at least percent of the fibers are oriented in the direction of the stress field;
- and
- curing a composite matrix around the fibers to form the jaw head.
