자동차 조향장치 비대칭 핀치요크의 원가절감을 위한 냉간단조 공정단축 설계 Process Reduction Design of Cold Forging for Cost-Saving of Asymmeric Pinch Yoke at Automobile Steering System
pp.1365-1370
This paper carried out design in order to reduce the process of asymmetric pinch yoke, one of the important parts which transfer power to wheels through gearing box in automobile steering system. The purpose of the study is to reduce prime costs and strengthen competitiveness by designing the total 8 processes including the up-setting and forging process of the No. 1 as the forging process the current method of production. The process with die stress analysis by using the finite element method have been carried out through new optimal die design. As this study result, it is expected that die life can be secured as excellent material flow and caused by forming load. A prototype has been produced by basis of the analysis result and the reduction of the process was successful. As the unit price is lower than that of the current process, the competitiveness can be expected.
