The present invention relates to a motorcycle bumper manufacturing method and a motorcycle bumper manufactured thereby. The method of manufacturing a bumper installed on the outermost side of a motorcycle body made of a metal bar to absorb an external shock applied to the motorcycle body includes: a primary bumper body formation step of making a metal pipe material penetrate into dies, while drawing the metal pipe material by installing a drawing means corresponding to an inner cross section of an LED groove on one side of the inner edge surface of the dies; a secondary bumper body formation step of cutting a primary bumper body, having a linear pipe shape with an LED groove dented on one side of the outer edge surface in a longitudinal direction, by a predetermined length; a tertiary bumper body formation step of bending a secondary bumper body cut by a predetermined length at a random angle in accordance with the exterior of an installation part of the motorcycle body by inserting the bumper body into a bending machine; and a wiring hole formation step of drilling a wiring hole towards the outer edge surface of the other side or a core part of the bumper body in the bottom of the LED groove having the shape of a curved groove dented along the outer edge surface of the bumper body having the shape of a bent pipe. Therefore, the method is capable of conveniently manufacturing a motorcycle bumper promoting safety and decorativeness.
본 발명은 오토바이용 범퍼의 제조방법 및 이에 의해 제조된 오토바이용 범퍼에 관한 발명으로, 오토바이 차체에 가해지는 외부충격을 흡수하도록 금속바로 이루어져 차체의 최외측에 설치하는 범퍼의 제조방법에 있어서, 금속 관체소재를 다이스에 통과하되, 다이스의 내주면 일측에 LED홈의 내형 단면에 상응하는 인발수단을 구비하여 인발하는 1차범퍼바디형성단계; 외주면 일측에서 길이 방향으로 LED홈이 요입된 직선관 형상의 1차범퍼바디를 일정 길이로 절단하는 2차범퍼바디형성단계; 일정 길이로 절단된 2차범퍼바디를 밴딩기에 투입하여 차체 설치부위의 외형에 따라 임의 각도로 절곡하는 3차범퍼바디형성단계; 및 절곡관 형상의 범퍼바디의 외주면을 따라 요입된 절곡홈 형상의 LED홈의 저면에서 범퍼바디의 심부 또는 타측 외주면을 향해 배선홀을 통공하는 배선홀형성단계;를 포함하여 구성함에 따라 안전성 및 장식성을 도출할 수 있는 오토바이용 범퍼를 간편하게 제조할 수 있는 것이 특징이다.
