摘要： PROBLEM TO BE SOLVED: To provide a method for forming grooves in a pipe, wherein the grooves are formed so that a round shape of an upper end of an inner wall becomes small, and actual depth of the grooves is increased. SOLUTION: In the method for forming grooves 61, 62 in an outer circumferential surface of a pipe 60 for a head rest stay, a first driving blade is a rectangular blade 52 in which its right and left surfaces 52a, 52b are perpendicular in the axial direction, and the width in the right-to-left direction is larger than the width between right and left inner walls 72a, 72b of a recess 72; a second driving blade is an inclined blade 51 in which its right surface 51b is perpendicular in the axial direction; the depth of the recess 72 and a wide recess 71 is determined so that a squeezed inner circumferential surface of the pipe 60 for the head rest stay is not brought into contact with bottom surfaces 72c, 71c of the recess 72 and the wide recess 71; the right and left surfaces 52a, 52b of the rectangular blade 52 are located outwardly to the right and to the left of the right and left inner walls 72a, 72b of the recess 72, respectively; and the right surface 51b of the inclined blade is located outwardly to the right of a right inner wall 71b of the wide recess 71, and then pressing is performed.

摘要： PROBLEM TO BE SOLVED: To prevent cracking in a groove or a fin during manufacturing.
SOLUTION: The ratio (R/δ) of the circular radius R mm of a bottom angular part (2b) of a groove (2) for the bottom width δ mm of the groove (2) is 0.10-0.25, and the ratio (r/δ) of the circular radius r mm at the tip of a fin (3) for the bottom width δ mm of the groove (2) is 0.14-0.20. Thereby, when rolling-machining, tubing materials (copper materials) can easily flow into the groove of a fluted plug.
