Abstract
Elongated pipes are internally peeled by positioning a machining head within the pipe while providing relative rotational and longitudinal movement between the pipe and machining head. An external clamping force is applied to the pipe generally radially of its longitudinal axis and in substantial alignment with the machining head for minimizing vibration of the pipe during the machining operation.
Claims16
Apparatus for internally machining elongated pipes and the like comprising:
- a machining head for internally machining a pipe or the like, drive means for providing relative rotational and longitudinal movement between the pipe and said machining head, and pipe clamping means positioned in cooperative relationship with said machining head generally radially outwardly thereof and in substantial alignment therewith for providing an external clamping force on the pipe generally radially inwardly of its longitudinal axis in substantial alignment with said machining head and for maintaining said cooperative relationship and said clamping force during relative rotational and longitudinal movement between the pipe and machining head to inhibit vibration of the pipe during machining thereof.
Apparatus for machining elongated pipes and the like comprising:
- a machining head for internally machining a pipe or the like, machining head drive means for rotatably driving said machining head, pipe drive means for longitudinally driving a pipe along said machining head from a leading pipe end toward a trailing pipe end, and pipe clamping means positioned in cooperative relationship with said machining head generally radially outwardly thereof and in substantial alignment therewith for providing an external clamping force on the pipe generally radially inwardly of its longitudinal axis in substantial alignment with said machining head and for maintaining said cooperative relationship and said clamping force as the pipe is longitudinally driven past said machining head and clamping means to inhibit vibration of the pipe during machining thereof.
A method of internally machining an elongated pipe or the like comprising the steps of:
- positioning a machining head within a pipe, rotatably and longitudinally moving the pipe and machining head relative to one another for internally machining the pipe in a direction from its leading end toward its trailing end, applying an external clamping force on the pipe generally radially inwardly of its longitudinal axis in substantial alignment with the machining head for minimizing vibration of the pipe, and maintaining said clamping force in substantial alignment with said machining head during said step of rotatably and longitudinally moving the pipe and machining head relative to one another.
A method of internally machining elongated pipe or the like comprising the steps of:
- positioning a machining head within a pipe, rotatably driving the machining head while longitudinally driving the pipe therepast in a direction from a leading pipe end toward a trailing pipe end, providing an external clamping force on the pipe generally radially inwardly of its longitudinal axis and in substantial alignment with the machining head, and maintaining said clamping force in substantial alignment with said machining head during said step of rotatably driving the machining head while longitudinally driving the pipe therepast.
