Axle Sleeve Manufacturing Process |
摘要 |
A system and method for the manufacture of aircraft landing gear axle equipment is provided of two primary steps: hot pierce and tube solid billet stock; and flow form process. The hot pierce and tube process converts a standard solid round billet by heating it well beyond its annealing temperature. The billet is then pierced with a lance and hot rolled into a seamless tube. The tube is then precision flow formed as an incremental metal forming technique in which a tube of metal is formed over a mandrel by a multiple rollers using tremendous pressure. The rollers deform the work piece, forcing it against the mandrel, simultaneously lengthening the part axially and radially thinning the cross-sectional wall of the workpiece. |
