摘要： PROBLEM TO BE SOLVED: To obtain a grooved plug that is manufactured by a heading process and does not have a tool mark caused by joining faces of split dies on a circumferential groove or on a lower surface of a head section.
SOLUTION: At a heading station S3 in the former stage, an intermediate product 1C comprising a solid shaft section 2 and a head section 3 arranged at one end of the shaft section 2 is formed by heading an columnar material b. At a heading station S4 in the latter stage, the outer periphery of the head section 3 of the intermediate product 1C is constrained by an outside punch 36 of a punch 35 that is equipped with a cylindrical outside punch 36 and an inside punch 37. Concurrently, a little lower part of the boundary part of the intermediate product 1C is constrained by split dies 24, 24 that have a forming cavity 24c to constrain the boundary part between the head section 3 and the shaft section 2 of the intermediate product 1C. Holding this state, only the top side of the shaft section 2 of the intermediate product 1C is headed and swelled using the punch 35 and a forming pin 32 on the dies side. In this way, the circumferential groove 4 having a round cross section without a tool mark caused by the split dies 24, 24 is formed in the boundary part between the shaft portion 2' for forming a screw and the head section 3.
