Description

Technical Field

[0001] The utility model relates to the technical field of wire processing, in particular to a flat wire rolling and forming device. Background Art

[0002] Flat wire is mainly used in the production of electrical connector components and luggage zipper wires. The traditional flat wire processing and rolling process is round wire billet, single double-roll flattening machine, annealing furnace, cooling, pickling, wire drawing machine, annealing furnace, cooling, pickling, and finished product drawing machine. First, the round wire billet is rolled into thick flat wire by a single double-roll flattening machine. Because the wire deforms greatly during the flattening process, the flat wire becomes hard and difficult to process in the subsequent process, so the thick flat wire needs to be placed in an annealing furnace for softening. An oxide layer is formed on the surface of the flat wire softened in the annealing furnace. The copper alloy flat wire is then pickled for surface treatment to remove the oxide layer on the surface. It is then transported to the wire drawing machine for preliminary drawing, and then annealed, cooled, pickled, and sent to the finished product drawing machine to be the finished product.
