Abstract

A state purpose to produce fine blanking die gets to be the maximum size of share surface the study considered that change a size of share area. the clearance affecting most greatly size of share surface fixing as 1% of material thickness and while change share speed, A distance change from share line to V-ring center, A change of V-ring angle. it designed. Each test specimen taken from the share surface size analysis of the V-ring distance of 2mm, the outer $45^{\circ}$ / inner$30^{\circ}$ if the, Shear speed was found that the area of the entire cross section is largest the 6.4m/min.

파인블랭킹 금형을 제작하는 주목적은 전단면의 크기를 최대가 되도록 하기 위함이다. 본 연구에서는 전단면의 크기에 가장 크게 영향을 미치는 클리어런스는 재료 두께의 1%로 고정시키고 전단라인에서 Vee-Ring 중심까지의 거리 변화, V-Ring 각도의 변화, 전단 속도를 변화시키면서 전단 면적의 크기 변화를 연구 고찰하였다. 각 실험으로부터 시편을 채취하여 전단면의 크기를 분석한 결과 V-링의 거리는 2mm, 각도는 외측$45^{\circ}$/내측$30^{\circ}$일 때, 전단 속도는 6.4m/min일 때 전단면의 크기가 가장 크게 됨을 알 수 있었다.
