#CMT# #/CMT# The method involves arranging a tubular work piece around a pressure mandrel (20). The pressure mandrel is displaced by rotation, and is remodeled by feeding a shaping mandrel (40). Wall thickness of the tubular work piece is reduced, where the tubular work piece is lengthened. The pressure mandrel is displaced in the axial direction against the work piece during remodeling. #CMT# : #/CMT# An independent claim is also included for a flow form milling device. #CMT#USE : #/CMT# Method for flow form milling. #CMT#ADVANTAGE : #/CMT# The pressure mandrel is displaced in the axial direction against the work piece during remodeling, and hence enables forming tubular work pieces into variety of shapes in an efficient manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of a forming step during a flow form milling method. 11,12,13 : Axial areas 20 : Pressure mandrel 28 : Cylinder section 40 : Shaping mandrel 42 : Rotation axis. |
