Abstract
The present disclosure provides a staged shearing and forming method for a T-bar cylindrical member, comprising: controlling a shear working surface of a shear spinning wheel in contact with a surface of a cylindrical member blank; controlling a circumferential rotation of the cylindrical member blank; controlling a working surface of a flow spinning wheel to be in perpendicular contact with a surface of the unsaturated I-bar cylindrical member and controlling the cylindrical member blank to be maintained in a circumferential rotational state; controlling the flow spinning wheel to thin one side of the unsaturated I-bar cylindrical member; controlling a fractal working surface of a fractal spinning wheel in contact with a top of the saturated I-bar structure; controlling a working surface of a flat spinning wheel to be in perpendicular contact with a surface of the Y-bar cylindrical member.
