A Study on the Rotary Shearing Operation of Sheet Metal
박판 금속의 회전 전단가공에 관한 연구
Abstract
Rotary shearing using of rotating and locally shear force has been studied. It is possible to be obtained in any case for requested blank diameters. In this paper, different local forming zones, that are clearances between upper roller and vertically taped low roller, were investigated. Required shearing force is calculated by undecided coefficient method for clearances and strokes of upper roller. Rotary shearing is completed undergoing some processes composed of pressing steps and standing steps. The reason for using these processes is to avoid jamming or tearing of blank by means of upper roller during shearing.
