The present invention relates to a hairline forming device for a curved object comprising: a base frame where an object is placed on; a guide unit installed in a top of the base frame to have a curved part in a shape corresponding to the object; a carriage unit mounted on the guide unit to make a reciprocating motion following the guide unit; a driving unit connected to the carriage unit to provide a driving force for the reciprocating motion to the carriage unit; a relay unit to connect the carriage unit and the driving unit to allow the carriage unit making the reciprocating motion move up and down following the curved part of the guide unit; and a scraping unit installed in a bottom of the carriage unit to contact a top surface of the object put on the base frame. According to the present invention, the scraping unit forms a hairline on the object by the reciprocating motion of the carriage unit following the guide unit in a shape corresponding to the object. A uniform hairline can be formed on the object, and a hairline forming device with a simple structure can be provided at low production costs. |
