Abstract
A tool and a method are disclosed for cutting coils in a dynamoelectric machine. In an embodiment, the tool includes a blade having a cutting edge on a distal end thereof. The blade is operably connected on a proximal end thereof to a double acting hydraulic cylinder. The tool further includes at least one guide arm coupled to and extending longitudinally in a distal direction from the double acting hydraulic cylinder, wherein the at least one guide arm is disposed alongside the blade and extends parallel to a path of the blade.
Claims20
A tool comprising:
- a blade having a cutting edge on a distal end thereof;
- a double acting hydraulic cylinder operably connected to a proximal end of the blade;
- and
- at least one guide arm connected to and extending longitudinally in a distal direction from the double acting hydraulic cylinder, wherein the at least one guide arm is disposed alongside the blade and extends parallel to a path of the blade.
A method of cutting at least one coil comprising:
- providing a tool including:
- a blade having a cutting edge on a distal end thereof,
- a double acting hydraulic cylinder operably connected to a proximal end of the blade, and
- a pair of guide arms connected to and extending longitudinally in a distal direction from the double acting hydraulic cylinder, wherein the at least one guide arm is disposed alongside the blade and extends parallel to a path of the blade;
- placing the tool such that the at least one coil is captured between the pair of guide arms;
- inserting a pin member through a hole in a distal end of each arm in the pair of guide arms such that the at least one coil is captured between the pin member and the blade;
- engaging the double acting hydraulic cylinder;
- retracting the blade;
- and
- removing the pin member.
