Abstract
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.
Claims8
In combination a pipe threading and cutting machine with independent threading and cutting capability, comprising
- a frame (2);
- a pipe clamping section (11) to hold a pipe (12) in the machine along an axis (12') while being restrained against rotation;
- a motor-driven pipe threading section (1) having a threading tool means (5, 49) therein;
- a pipe cutting section (6) having a pipe cutting tool means (10) therein, the pipe threading section (1) and the pipe cutting section (6) being located -- with respect to the axis (12') -- at the same side of the pipe clamping section (11) and spaced from each other by a predetermined distance along the axis (12')
- guide means (30, 31) extending parallel to said axis (12') to guide the clamping section (11),
- means for moving the clamping section over a distance which is greater than the distance (D) between the side of the threading tool means (5, 49) of the threading section (1) which faces the clamping section (11) and the side of the cutting tool means (10) of the cutting section (6) which faces the clamping section (11);
- the pipe threading section (1) and the pipe cutting section (6) are separate, independently driven units;
- means for pivotably and removably securing said pipe threading section (1) to the frame to pivot in a plane transverse to the axis (12') and includes an individual threader drive motor (3), means for removably securing the pipe cutting section (6) to the frame (2) of the machine and includes an individual cutter drive motor (54);
- and means (32) are provided to secure the clamping section (11) to the frame (2) of the machine and fix the position of the clamping section on the guide means (30, 31) with respect to the frame (2).
