Abstract

Apparatus for successive cut-off operations at axially spaced locations along an elongated tubular workpiece wherein the workpiece is rotated during cut-off operations and successively advanced axially between such operations. The cut-off operations occur at a work station where a front portion of the workpiece is successively advanced, rotated and severed with an elongated portion of the workpiece extending rearwardly from the work station. A pair of elongated guide and support rails extend adjacent the rearwardly projecting portion of the workpiece and mount a workpiece supporting mechanism which is freely moveable therealong toward and away from the work station. The mechanism comprises a freely rotatable collet assembly adapted to grip and release the workpiece. Operating means for the collet assembly comprise a handwheel, a gear train, and a shell cam which is rotatable through a limited angle and axially moveable at the urging of the handwheel and gear train. Axial cam movement results in axial movement of a collet actuating sleeve to open the collet and a compression spring closes the collet. An auxiliary collet opening arm mounted on the shell cam is engaged by a fluid operated cylinder to rotate the cam and automatically open the collet when the workpiece supporting mechanism is incrementally drawn forwardly along the guide rails by the successively advancing workpiece to a position of proximity with the work station.
