ABSTRACT:
A device for feeding and discharging a work in an automatic hollow-pipe cutting apparatus comprises: a cutter device for cutting a hollow pipe; a cam lever driving mechanism for sending the hollow pipe to the cutter device; a fixed chuck device disposed near the cutter device; a movable chuck device disposed away from the cutter device; a movable die core disposed inside the cutter device and inside the hollow pipe; another cam lever driving mechanism for moving the movable chuck device; a stopper and ejector fitted to the fixed die core; whereby when the hollow pipe is fed to the cutter device, the fixed chuck device grasps and release the hollow pipe and the movable chuck device also grasps and release the hollow pipe but at timing different from grasping and releasing by the fixed chuck means and the feeding of the hollow pipe into the cutter device is performed by movement of the movable chuck device by means of the other cam lever driving mechanism, and after the hollow pipe is cut, during lowering of a slider which accommodate the stopper and ejector and a movable shearing cutter of the cutter device, the stopper and ejector is sent back by means of a cam in the direction reverse to the feeding direction of the hollow pipe into the cutter device so that a cut piece is discharged.
