A die head has replaceable radially slidable threading dies moved by a bushing with cams. As the workpiece is threaded to the desired length, its end contacts cam surfaces which move a sensor bolt and a control pin to disengage the bushing from a locked position. The bushing can then move axially to radially retract the threading dies from the workpiece.

Die head with workpiece actuated release

To simplify the apparatus and reduce handling, a pipe threading section and a pipe cutting section are axially aligned with respect to a pipe clamping apparatus, both located at the same side of the pipe clamping section. A guide is provided, extending parallel to the axis of the pipe, to guide the clamping section on the apparatus for movement in selected positions, the moving distance of the clamping section being greater than the distance between that side of the threading tool of the pipe threading section and the cutting tool of the cutting tool section which faces the clamping section.

Pipe machining apparatus, particularly combination pipe threading and

In a pipe cutting device, a stationary chuck for holding a workpiece is connected to a bearing housing, the chuck and bearing housing are in axial alignment. A ring is concentrically mounted within the bearing housing and a cutting support is eccentrically pivotally mounted in the ring and carries a cutting member. The cutting support can be pivoted between a rest position with the cutting member spaced from the workpiece to a cutting position with the cutting member in contact with the workpiece. From the cutting position, the cutting support engages and drives the ring so that both the cutting support and ring move along a concentric path about the workpiece for effecting the cutting operation.
