Measurement and FEM Analysis of Elastic Deformation According to the Forging Stages in Cold Forging Die
냉간단조용 금형의 변형모드에 따른 탄성변형량의 측정 및 유한요소 해석
Abstract
In cold forging, the elastic behavior of the die has a direct influence on the accuracy of the forging part. And the die dimension is continuously changed during the loading, unloading, and ejecting stage. In this paper, we evaluated the elastic deflections of cold forging die during loading, unloading, and ejecting stage. Uni-axial strain gauges are used to measure elastic strain of die during each forging stage. Strain gauges are attached on the surface of die. A commercial F.E.M code, DEFORM-2D
