Abstract
This paper analyzes the mechanism of fiber bending and elongation of integrated piercing process, and builds the mechanical model of steely needle, then discusses the increasing and decreasing relation between maximum bending stress, maximum shear stress and the resistance that acts on needlepoint and radius and length of needlepoint, then optimizes the form of needlepoint according to the result.
Keywords
integrated piercing ; bending stress ; shear stress ; radius of needlepoint ; length of needlepoint ; optimization
