A STUDY ON THE ESTINMATION OF BLANK HOLDER FORCE IN SQUARE CUP DRAWING
정사각용기의 성형시 블랭크 홀더력에 관한 연구
Abstract
IN this study when drawing a square cup blank holder pressure necessary for flange wrinkling prevention was experimentally studied. The materials used in the experiment were SPCC and SUS304 and drawing ratio was 1.62∼2.0 Two case for lubrication condition were experimented. One was without lubricant and the other was with lubrication of high viscosity.
