Disclosed are a bumper beam for a vehicle, and a manufacturing method thereof. According to an embodiment of the present invention, the method comprises: a curved line forming step of forming two first curved lines on an upper and a lower side of a central part of a panel in a longitudinal direction, and forming four second curved lines in parallel to an inside of the first curved lines on both ends of the panel; a cut part forming step of forming a cut part by cutting the panel towards an outside of a diagonal direction going from a point wherein the two first curved lines meet the four second curved lines to a central part; a curve forming step of curving the panel at right angles based on the two first curved lines and the four second curved lines; a banding step of making an outer part of both ends of the panel banded while being inserted into the central part by banding both ends of the panel based on a banding line, wherein the first and second curved lines meet each other on the upper and lower directions; and an attachment step of attaching both ends, inserted into both sides of the central part of the panel, to each other.

    차량용 범퍼빔 및 그 제조방법이 개시된다. 본 발명의 일 실시 예에 따른 차량용 범퍼빔의 제조방법은 패널 상의 중앙부 상측과 하측에 길이방향을 따라 2개의 제1절곡선을 형성하고, 상기 패널 상의 양 단부에는 각 제1절곡선의 내측으로부터 평행한 4개의 제2절곡선을 형성하는 절곡선 형성단계; 상기 각 제1절곡선과 상기 4개의 제2절곡선이 만나는 점으로부터 중앙부를 향하는 사선방향 외측으로 상기 패널을 절개하여 절개부를 형성하는 절개부 형성단계; 상기 패널 상의 2개의 제1절곡선과 상기 4개의 제2절곡선을 기준으로 상기 패널을 직각으로 절곡하는 절곡 성형단계; 상기 절곡 성형된 패널 상의 제1절곡선과 제2절곡선이 각각 상하방향으로 만나는 밴딩선을 기준으로 상기 패널의 양 단부를 밴딩 성형하여 상기 패널의 양 단부 외측이 상기 중앙부 내측으로 끼워지면서 밴딩되도록 하는 밴딩 성형단계; 및 상기 패널의 중앙부 양측에 각각 끼워진 양 단부를 상호 접합하는 접합단계;를 포함한다.
