드로비드가 판재성형에 미치는 영향에 관한 실험적 연구
An Experimental Study on the Effect of the Draw-beads in Sheet Metal Forming
초록
Experiments on the drawability of squared boxes have been performed under various working conditions. In the present work, the pattern of material flow and the local change in the thickness of shell are used as the measures of drawability, and they are measured using the photo-etching technique. The effects of the size of draw bead, the magnitude of blank holding force and the condition of lubrication on the drawability of squared boxes have been analyzed.
