SUS 육각봉 인발성형 시스템의 몰드 프레임에 관한 구조 안정성 평가

Abstract

SUS hexagonal bar has been widely used to make many kinds of hexagonal bolt/nuts and fittings. Peeling machine is used to make lustrous and clean surface of SUS circular bar in order to remove rust and impurities from surface of raw SUS circular bar. Similarly, roll unit system is used to make SUS hexagonal bar from SUS circular bar with lustrous and clean surface. Roll unit system is mainly divided into two parts ; one is roll unit and the other is mold frame. The purpose of this study was to evaluate the structural stability of mold frame supporting roll unit with numerical analysis. As the numerical analysis result, higher structural stability was gradually shown in order of models 4, 2, 3 and 1. It was considered that the structural stability of this study was influenced by the decrease of mold frame size, especially height decrease.
