Abstract
A biased closed crimping head for a hydraulic power tool. The crimping head comprises a first pivoting pin and a first jaw disposed for rotation about a first axis defined by the first pivoting pin. The crimping head further comprises a second pivoting pin and a second jaw disposed for rotation about a second axis defined by the second pivoting pin. An extension spring is operatively coupled to the first jaw and the second jaw so that the jaws reside in a biased closed position. During a crimping action, the first jaw rotates about a first axis defined by the first pivoting pin, and the second jaw rotates about a second axis defined by the second pivoting pin.

A biased closed crimping head for a hydraulic power tool, the crimping head comprising:
- a first pivoting pin;
- a first jaw disposed for rotation about a first axis defined by the first pivoting pin, a first die pin bore extending through an upper head portion of the first jaw;
- a second pivoting pin;
- a second jaw disposed for rotation about a second axis defined by the second pivoting pin, a second die pin bore extending through an upper head portion of the second jaw;
- and
- an extension spring configured to bias the jaws toward closed position,
- wherein during a crimping action, the first jaw rotates about the first axis defined by the first pivoting pin, and
- the second jaw rotates about the second axis defined by the second pivoting pin.
A biased closed crimping head for a hydraulic power tool, the crimping head comprising:
- a first pivoting pin;
- a first jaw disposed for rotation about a first axis defined by the first pivoting pin, wherein a portion of a contour of the first jaw is shaped as an arc and configured as a first die mount;
- a second pivoting pin;
- a second jaw disposed for rotation about a second axis defined by the second pivoting pin, wherein a respective portion of a respective contour of the second jaw is shaped as a respective arc and configured as a second die mount;
- a first die removably secured within the first die mount;
- a second die removably secured within the second die mount;
- and
- an extension spring configured to bias the jaws toward closed position,
- wherein during a crimping action, the first jaw rotates about the first axis defined by the first pivoting pin, and
- the second jaw rotates about the second axis defined by the second pivoting pin.
A biased closed crimping head for a hydraulic power tool, the crimping head comprising:
- a first pivoting pin;
- a first jaw disposed for rotation about a first axis defined by the first pivoting pin, wherein a portion of a contour of the first jaw is shaped as an arc and configured as a first die mount;
- a second pivoting pin;
- a second jaw disposed for rotation about a second axis defined by the second pivoting pin, wherein a respective portion of a respective contour of the second jaw is shaped as a respective arc and configured as a second die mount;
- a first die;
- a first die pin disposed in a first die pin bore extending through an upper head portion of the first jaw from an outer surface of the first jaw to the first die mount, wherein the first die pin comprises a rectangular protrusion provided at an end of the first die pin, and wherein the first die includes an external groove provided along an outer surface of the first die such that the rectangular protrusion of the first die pin engages the external groove of the first die to removably secure the first die within the first die mount;
- a second die;
- a second die pin disposed in a second die pin bore extending through a respective upper head portion of the second jaw from a respective outer surface of the second jaw to the second die mount, wherein the second die pin comprises a respective rectangular protrusion provided at an end of the second die pin, and wherein the second die includes a respective external groove provided along a respective outer surface of the second die such that the respective rectangular protrusion of the second die pin engages the respective external groove of the second die to removably secure the second die within the second die mount;
- and
- an extension spring configured to bias the jaws toward closed position,
- wherein during a crimping action, the first jaw rotates about the first axis defined by the first pivoting pin, and
- the second jaw rotates about the second axis defined by the second pivoting pin.
