Abstract
A cutter for cutting a member has a first jaw and a second jaw mounted relative to each other to articulate along a range of motion between an open condition and a closed condition. The jaws are configured to provide a shearing action cutting between the first jaw and the second jaw on a first side of the member and an opposite shearing action cutting on an opposite second side of the member. In a single stroke cutting method the edges come together. They may be at an angle off-parallel to each other or oppositely stepped and intersecting in superposition. With centrally recessed edges, there may be opposite bypass cutting on opposite sides of the member. In a central region between the first side and the second side, there may be no bypass (e.g., approach being more conventional non-bypass cleaving).
Claims29
A cutter (20;
- 100;
- 140;
- 260) having:
- a first jaw (26;
- 100;
- 142;
- 262;
- 310;
- 410;
- 800;
- 840) having an edge having first and second portions;
- and
- a second jaw (28;
- 102;
- 144;
- 264;
- 310;
- 412;
- 800;
- 840) having an edge having first and second portions, the first jaw and second jaw mounted relative to each other to articulate along a range of motion between an open condition and a closed condition,
- wherein:
- the first jaw first edge portion is offset from the second jaw first edge portion and the first jaw second edge portion is oppositely offset from the second jaw second edge portion.
A cutter for cutting a member, the cutter comprising:
- a first jaw;
- and
- a second jaw, the first jaw and second jaw mounted relative to each other to articulate along a range of motion between an open condition and a closed condition,
- wherein:
- the first jaw and second jaw are configured to provide a shearing action cutting between the first jaw and the second jaw on a first side of the member and an opposite shearing action cutting between the first jaw and the second jaw on a second side of the member opposite the first side.
A cutter having:
- a first jaw having a first edge;
- and
- a second jaw having a second edge non-parallel to the first edge, the first jaw and second jaw mounted relative to each other to articulate along a range of motion between an open condition and a closed condition.
A method for cutting a member, the method comprising, in a single stroke:
- a shearing action cutting between a first jaw and a second jaw on a first side of the member;
- and
- an opposite shearing action cutting between said first jaw and said second jaw on a second side of the member opposite the first side.
A tool (320) comprising:
- a first jaw (322) having a first face and a second face;
- a second jaw (324) having a first face and a second face;
- and
- a hinge mechanism (356) coupling the first and second jaws for rotation relative to each other about a hinge axis (520) and comprising:
- a first annular channel (362) in the first faces of the first and second jaws;
- a second annular channel (364) in the second faces of the first and second jaws;
- a first side member (358) having an annular protrusion (366) accommodated in the first annular channel;
- and
- a second side member (360) having an annular protrusion (368) accommodated in the second annular channel.
A cutting insert (410, 412;
- 800;
- 840;
- 880) for use with a tool, the cutting insert comprising:
- a cutting portion (420);
- and
- an arcuate retaining portion (422) for retaining the cutting insert to the tool.
