알루미늄호일림의 제조법Manufacturing method of aluminum foil rim

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 차량의 알루미늄호일림의 단면 및 림의 외면 및 내면에 있어서의 여러부분의 응력의 분표를 표시하는 도면. 제2도는 여러 부분에 있어서의 림의 두께가 부호 A, B, C …I 및 J에 의하여 표시되어 있는 림의 단면을 표기하는 단면도. 제3도는 각각 순차실시되는 프레스가공 및 전동압가공의 제단계에서 본 발명에 의하여 제조되는 림의 단면을 표시하는 도면. 제4도 내지 제9도는 소재가 순차 가공되어 림을 형성하는 양상을 각각 표시하는 단면도.1 is a diagram showing a section of stress of various parts on the cross section of an aluminum foil rim of a vehicle and on the outer and inner surfaces of the rim; 2 shows that the thicknesses of the rims in various parts are denoted by symbols A, B, C,. Sectional drawing indicating the cross section of the rim indicated by I and J. 3 is a view showing a cross-section of the rim produced by the present invention in the first step of the press working and electro-pneumatic processing sequentially performed respectively. 4 to 9 are cross-sectional views showing aspects in which materials are sequentially processed to form rims.

Claims (3)

두께가 얇은 원통 알루미늄 또는 알루미늄 합금재료를 프레스기계의 다이 및 이것과 협등하는 펀치의 테이퍼 부분을 거쳐서 작동하는 압축응력의 작용을 의하여 축선방향으로 프레스 가공하여 재료의 직경을 확대시키고 알루미늄 호일림의 소요의 형상을 형성하는 동시에 재료의 두께를 다이 및 펀치의 테이퍼 부분을 거쳐서 압축응력이 부여되는 부분에서 증대시켜 이것에 의하여 그렇지 않으면 재료의 전동압연성형가공중에 두께가 얇아지는 것에 의하여 약화를 일으키는 경향이 있는 부분에 있어서 재료의 기계적강도를 증대시키게 한 알루미늄호일림의 제조법.The thin cylindrical aluminum or aluminum alloy material is pressed in the axial direction by the action of the compressive stress acting through the die of the press machine and the tapered portion of the punch to be equal to this to enlarge the diameter of the material and At the same time, the thickness of the material is increased at the portion where compressive stress is applied through the tapered portion of the die and punch, thereby causing a tendency to weaken due to the thinning of the material during electric rolling forming of the material. A method for producing aluminum foil rims, which increases the mechanical strength of a material at a part thereof. 재료의 내경 D에 대한 높이 H의 비 H/D를 1.5에 같거나 그 이하로 선정하여 내경 D에 대한 재료의 두께 t의 비 t/D를 0.006 내지 0.06의 범위로 설정하는 동시에 재료의 평균변형저항을 10 내지 25kg/mm2의 범위로 설정하여 다이 및 펀치의 테이퍼부분의 경사각을 10 내지 65°의 범위로 설정한 특허청구의 범위 제1항 기재의 방법.The ratio H / D of the height H to the inner diameter D of the material is equal to or less than 1.5, and the ratio t / D of the thickness t of the material to the inner diameter D is set within the range of 0.006 to 0.06, and the average strain of the material The method according to claim 1, wherein the inclination angles of the tapered portions of the die and punch are set in the range of 10 to 65 degrees by setting the resistance in the range of 10 to 25 kg / mm 2 . 길이방향으로 홈이 있는 다이 및 이것과 형동하는 재료의 각각의 측부에 있어서 한쌍의 펀치의 테이퍼부분을 거쳐서 작동하는 압축응력의 작용에 의하여 재료의 양측을 동시에 축선방향으로 압축하는 것에 의하여 된 특허청구의 범위 제1항 기재의 방법.Claims made by simultaneously compressing both sides of a material in the axial direction by the action of a compressive stress acting through a tapered portion of a pair of punches on each side of the die with grooves in the longitudinal direction and the material to be shaped therewith Scope The method of claim 1. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
