Abstract

PURPOSE:To facilitate working and to obtain a terminal working pipe having high dimensional accuracy of the outer diameter by finishing in the necessary dimension by pipe expanding or swaging. CONSTITUTION:For swaging a pipe 4, it is held by the fixed clamp die 3a on whose inner peripheral face a bead 2 is formed and a mobile clamp die 3b and subjected to punching by moving a punching die 6 to the pipe 4 side in this state. In this case, the pipe 4 is subjected to ironing by the punching die 6 by inserting the pin 5 having the outer diameter same as its inner diameter into the pipe 4 and worked in a small outer diameter. The outer peripheral face of the pipe subjected to swaging is thus finished in the necessary dimensional and mirror face.
