Abstract
An expansion tool includes a housing, a motor supported by the housing, a mandrel, and a drive mechanism configured to convert a rotational input from the motor into translational movement of the mandrel between an extended position and a retracted position. The expansion tool is configured to perform cycles of axially extending and retracting the mandrel. An elapsed time for one cycle of moving the mandrel from the retracted position to the extended position and back to the retracted position defines a cycle time of the expansion tool. The cycle time is one second or less.

An expansion tool comprising:
- a housing;
- a motor supported by the housing;
- a mandrel;
- and
- a drive mechanism configured to convert a rotational input from the motor into translational movement of the mandrel between an extended position and a retracted position,
- wherein the expansion tool is configured to perform cycles of axially extending and retracting the mandrel,
- wherein an elapsed time for one cycle of moving the mandrel from the retracted position to the extended position and back to the retracted position defines a cycle time of the expansion tool, and
- wherein the cycle time is one second or less.
An expansion tool comprising:
- a housing;
- a motor supported by the housing;
- a mandrel;
- and
- a drive mechanism configured to convert a rotational input from the motor into translational movement of the mandrel between an extended position and a retracted position,
- wherein the expansion tool is configured to perform cycles of axially extending and retracting the mandrel,
- wherein the mandrel is movable from the retracted position to the extended position in a first time period,
- wherein the mandrel is movable from the extended position to the retracted position in a second time period different than the first time period, and
- wherein the first time period and the second time period collectively define a cycle time of the expansion tool.
