Abstract
Shear tools are described. In one version, the shear tools include a pair of pivotally movable jaws positioned between sideplates. Various shearing dies are also described. Also described are systems and related methods utilizing the shear tools and dies which enable convenient shearing or severing of workpieces such as threaded rods.
Claims20
A tool head and dies for severing a workpiece, the tool head and dies comprising:
- a pair of pivotally attached jaws, the pair of jaws including a first jaw defining a first die recess, and a second jaw defining a second die recess;
- a first die disposed in the first die recess, the first die having a front projection, a medial projection, and a rearwardly located stop member, the first die defining a first capture region between the front projection and the medial projection, and a second capture region between the medial projection and the stop member;
- a second die disposed in the second die recess, the second die having a front projection, a medial projection, and a rear projection, the second die defining a first capture region between the front projection and the medial projection, and a second capture region between the medial projection and the rear projection;
- wherein the stop member of the first die has a height greater than the height of at least one of the medial projection of the first die and the front projection of the first die;
- and
- wherein the first die defines a bottom surface opposite the first and second capture regions, and the height of the stop member, the medial projection, and the front projection are measured from the bottom surface of the first die.

A tool system comprising:
- a power assembly including a body, a handle, and a motor;
- a tool head including a pair of pivotally attached jaws, the pair of jaws having a first jaw defining a first die recess, and a second jaw defining a second die recess;
- and
- a first die disposed in the first die recess, the first die having a front projection, a medial projection, and a rearwardly located stop member, the first die defining a first capture region between the front projection and the medial projection, and a second capture region between the medial projection and the stop member;
- a second die disposed in the second die recess, the second die having a front projection, a medial projection, and a rear projection, the second die defining a first capture region between the front projection and the medial projection, and a second capture region between the medial projection and the rear projection;
- wherein the stop member of the first die has a height greater than the height of at least one of the medial projection of the first die and the front projection of the first die;
- and
- wherein the first die defines a bottom surface opposite the first and second capture regions, and the height of the stop member, the medial projection, and the front projection are measured from the bottom surface of the first die.
5 more elements
At least two dies adapted for use with a tool head having a pair of jaws, the at least two dies comprising:
- a first die having a front projection, a medial projection, and a rearwardly located stop member, the first die defining a first capture region between the front projection and the medial projection, and a second capture region between the medial projection and the stop member;
- a second die having a front projection, a medial projection, and a rear projection, the second die defining a first capture region between the front projection and the medial projection, and a second capture region between the medial projection and the rear projection;
- wherein the stop member of the first die has a height greater than the height of at least one of the medial projection of the first die and the front projection of the first die;
- wherein the first die defines a bottom surface opposite the first and second capture regions, and the height of the stop member, the medial projection, and the front projection are measured from the bottom surface of the first die;
- and
- wherein the rear projection of the second die has a height less than the height of at least one of the medial projection of the second die and the front projection of the second die.
