립(Lip) 금형을 이용한 원형 빌렛 직경 이상의 판재 압출에 대한 연구
Investigation into Extrusion of Plate Wider than the Diameter of the Round Billet Using Lip Die
초록
In the extrusion process, the working material is forced to flow through a die with the desired profile. In general the width of m extruded section is limited to about an inch less than the diameter of the round billet But through the lip die, material is spreaded to produce a wider extruded section than the diameter of round billet. In this study, the extrusion process of an aluminum plate using the lip die is investigated. The width of extruded plate is 450nm that is formed form the round billet with a diameter of 250mm. The flow characteristic through the lip die is considered to produce the wide-extruded plate with a small billet.
