Abstract
A tool configured to form a groove in a pipe includes a housing, a spindle rotatable about a drive axis, a die shaft defining a die shaft axis, a die rotatably coupled to the die shaft about a die axis that is offset relative the die shaft axis, the die configured to form a groove into the pipe, and a drive assembly. The drive assembly includes a spindle drive portion configured to rotate the spindle about the drive axis and thereby rotate the tool with respect to the pipe, and a die shaft drive portion configured to rotate the die shaft to vary a distance between the die axis and the drive axis.
Claims19
A tool comprising:
- a housing;
- a spindle rotatable about a drive axis;
- and
- a drive assembly including an electric motor configured to rotate the spindle about the drive axis and thereby rotate the tool with respect to a pipe and a battery removably coupled to the housing, wherein the electric motor is powered by the battery.
A tool comprising:
- a housing;
- a spindle rotatable about a drive axis;
- a battery receptacle configured to receive a battery;
- a first motor configured to rotate the spindle about the drive axis and thereby rotate the tool with respect to a pipe;
- a die rotatably coupled to a die shaft about a die axis that is offset relative the drive axis, wherein the die is configured to create a groove into the pipe;
- and
- a second motor configured to rotate an input shaft about an input shaft axis to rotate the die shaft and vary a distance between the die axis and the drive axis.
A tool comprising:
- a housing;
- a spindle rotatable about a drive axis;
- a first electric motor configured to rotate the spindle about the drive axis and thereby rotate the tool with respect to a pipe;
- a die rotatably coupled to a die shaft about a die axis that is offset relative the drive axis, wherein the die is configured to create a groove into the pipe;
- a second electric motor operable to clamp the pipe between the spindle and the die;
- and
- a battery removably coupled to the housing,
- wherein the first electric motor and the second electric motor are powered by the battery.
