Disclosed is a manufacturing method for an automobile emblem and an automobile emblem using the same, capable of improving the productivity of the emblem and reducing manufacturing costs. According to an embodiment of the present invention, the manufacturing method for an automobile emblem includes: a blanking step of detaching an emblem material in a size capable of manufacturing the automobile emblem for a vehicle from a plate having a predetermined thickness; a pinhole processing step of forming multiple pinholes of a predetermined depth through a punching process on the rear surface of the emblem material formed in the blanking step; an emblem material forging step of reducing the thickness by compressing the emblem material passing through the pinhole processing step by a forging process and forming a caulking unit protruding from the rear surface in a periphery unit of the pinhole; a fixing pin compressing and fixing step of fixing a fixing pin by compressing the caulking unit to fill the pinhole after the front end of the fixing pin is arranged in the pinhole of the emblem material which passes through the emblem material forging step, wherein the fixing pin has an outer flange with the same outer circumference as the inner circumference of the pinhole at the front end unit; and an emblem body processing step of machining the emblem material after the fixing pin compressing and fixing step to form the emblem body so that the emblem material corresponds to the shape of the automobile emblem.

    자동차용 엠블럼 제조방법이 개시된다. 본 발명의 일 실시예에 따른 자동차용 엠블럼의 제조방법은, 소정두께의 판재에서 자동차용 엠블럼을 제작할 수 있는 사이즈로 엠블럼 소재를 떼어내는 블랭킹단계; 상기 블랭킹단계에서 만들어진 상기 엠블럼 소재의 배면에 펀칭가공을 통해 소정 깊이의 핀-홀을 복수개 형성하는 핀-홀 가공단계; 상기 핀-홀 가공단계를 거친 상기 엠블럼 소재를 단조가공으로 압착하여 두께를 줄이되, 배면에서는 상기 핀-홀의 주변부에 코킹부를 돌출 형성시키는 엠블럼 소재 단조단계; 선단부에는 상기 핀-홀의 내경과 동일한 외경을 갖는 외향플랜지가 형성된 고정핀의 선단을 상기 엠블럼 소재 단조단계를 거친 상기 엠블럼 소재의 핀-홀에 배치한 후 상기 핀-홀을 메꾸도록 상기 코킹부를 압착하여 상기 고정핀을 고정하는 고정핀 압착고정단계; 및 상기 고정핀 압착고정단계 이후에 상기 엠블럼 소재를 기계가공하여 자동차용 엠블럼 형상에 부합되도록 엠블럼 본체로 가공하는 엠블럼 본체 가공단계;를 포함한다.
