Abstract
A hydraulically activated shear is provided. The shear includes: a first jaw; a second jaw configured to slide past the first jaw in a shearing motion; and a first cutting plate attached to at least one side of the first and second jaws, the first cutting plate defining a shear edge and a shear surface, the shear surface having a positive camber with respect to a plane perpendicular to the jaws, wherein at least one of the first and second jaws is actuated by a hydraulic cylinder.
Claims20
A shear comprising:
- a first jaw having a first side extending along a shearing plane perpendicular to a pivot shaft;
- a second jaw having a second side extending along the shearing plane, the first and second jaws configured pivot with respect to each other about the pivot shaft to slide the second side of the second jaw past the first side of the first jaw in a shearing motion;
- and
- a first cutting plate extending along the shearing plane and attached to at least one of the first side of the first jaw and second side of the second jaw, the first cutting plate defining a cutting edge and a cutting surface, the cutting surface having a positive camber with respect to the shearing plane such that the cutting edge is positioned in the shearing plane.
1 more element
A shear comprising:
- a first means for shearing extending along a shearing plane perpendicular to a pivot shaft;
- a second means for shearing extending along the shearing plane and configured to slide past the first means for shearing in a shearing motion;
- and
- a means for providing a cutting edge extending along the shearing plane and attached to at least one side of the first and second means for shearing, the first cutting means defining a cutting edge and a cutting surface, the cutting surface having a positive camber with respect to the shearing plane.
1 more element
A shear comprising:
- a first jaw having a first shear surface extending along a shearing plane perpendicular to a pivot shaft;
- a second jaw having a second shear surface extending along the shearing plane,
- wherein the first and second jaws are configured to slide past each other along the shearing plane and wherein at least one of the first and second shear surfaces has a positive camber and is cambered toward the shearing plane.
