Title:
SUPPLYING/DISCHARGING DEVICE FOR WORKPIECE IN AUTOMATIC CUTTER FOR HOLLOW PIPE
Document Type and Number:
Japanese Patent JP3408899
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To rapidly and appropriately supply and discharge a hollow pipe which is fed to a cutter by a cam-lever driving mechanism, by discharging a workpiece by returning/feeding operation by a cam which serves as both a stopper and an injector.
SOLUTION: After a hollow pipe 48 is held by a movable chuck device 45, the movable chuck device 45 is moved in the direction of a cutter 50 while holding the hollow pipe 48, and the movement of the movable chuck device 45 is stopped in a position where the left end of the hollow pipe 48 is brought in contact with the right end of a cam which serves as both a stopper and an injector. At that time, a fixed chuck device 30 also simultaneously holds the hollow pipe 48 so that the hollow pipe 48 is automatically cut by the cutter 50. After the hollow pipe 48 is cut, a workpiece is discharged from the upper part of a fixed core by the cam which serves as both the stopper and the injector.
