The present invention relates to an apparatus for forming a groove of a headrest stay, which comprises: a main frame (2); a fixing unit (6) which comprises: a bottom fixing plate (8) where a stay is placed in the main frame (2); and a top fixing plate (10) to be combined vertically with the bottom fixing plate (8) to fix the movements of the stay (4) by pressurizing the top of the stay (4); a pressurizing cylinder (22) for elevating the top fixing plate (10); a roller booth (36) where one or more rollers (34) having different diameters are installed; and a roller conveying cylinder (28) for elevating the roller booth (36) to pressurize one side of the stay (4) by stages with the roller (34) and form a groove on the stay (4). Since the process for forming a groove on the headrest stay (4) is simple, the work time is reduced and the production volume can be increased. Since the groove is not formed by cutting but by pressurizing, no chips are scattered by cutting and the work can be facilitated. |
