Abstract

PURPOSE: To efficiently shear off a pipe to a prescribed width, by simultaneously rotating the pipe and a cutting-off die holding the outside of the pipe and by translating an internally set mandrel perpendicularly to the axis of the pipe to expand it.
CONSTITUTION: A cutting-off die 10 and a pipe 12 are set in a first main shaft 11. A mandrel 13 supported by a second main shaft 14 is inserted into the pipe 12. When the main shaft 11 is rotated and the mandrel 13 is elevated perpendicularly to the axis of the pipe 12, the pipe is sheared off at its front end to a prescribed width by the tip edge of the mandrel and the inside edge of the die 10. At that tiem, no sheared chip is made.
