METHOD FOR MAKING METAL PROFILES BY LONGITUDINAL MULTI-PASS ROLL FORMING

摘要

use: in the processing of metals by pressure. the essence of the u0438u0437u043eu0431u0440u0435u0442u0435u043du0438u00a0: a method includes deformation of the cylindrical plates, rollers u043du0430u043au0430u0442u044bu0432u0430u043du0438u0435u043c distort. in the process of u043du0430u043au0430u0442u044bu0432u0430u043du0438u00a0 will move in the direction opposite the direction of longitudinal bending. 1 il.
