Rolling device for forming of copper alloy flat wires

Abstract

The invention discloses a rolling device for forming of copper alloy flat wires. The rolling device comprises a wire-unwinding mechanism, a plurality of sets of rolling mills, a synchronous tension mechanism, an electrical control system and a wire-rewinding machine. The wire-unwinding mechanism comprises a wire-unwinding plate and a halt air brake device. The rolling mills are composed of more than two stand-alone mills, and each rolling mill is composed of a rolling roller, a support, an electromotor and a belt. The synchronous tension mechanism is composed of a potentiometer, a connection rod, a guide wheel and a spring support. The electrical control system is composed of an electric cabinet, an electrical element, electric wires and cables and provides power for each rolling mill. According to the rolling device, a multi-channel continuous rolling method is utilized, the rolling device is high in accuracy, processing procedures of the copper alloy flat wires are shortened, operation speed is 1.5-2.0 times that of a conventional stand-alone mill, and production efficiency is improved. Meanwhile, as gradual rolling during a rolling process is utilized, the rolling size is very stable, the surfaces of the flat wires are smooth and bright, the fact that grooves and roughness of the surfaces of the flat wires occur in a drawing process of a traditional mould is avoided, and product quality is improved.

Description

technical field [0001] The invention relates to the field of production and processing of copper alloy wires, in particular to a rolling device for forming copper alloy flat wires. Background technique [0002] Copper alloy flat wire is mainly used in the production of electrical connector components and luggage zipper wires. The traditional processing and rolling process of copper alloy flat wire is round wire blank, single double-roller flattening machine, annealing furnace, cooling, pickling, wire drawing machine, annealing furnace, cooling, pickling, finished product drawing machine. First, the copper alloy round wire blank is rolled into a thick flat wire by a single double-roller flattening machine. During the flattening process, the wire rod deforms greatly and the flat wire becomes hard and difficult to process later. Therefore, it is necessary to The thick flat wire is placed in an annealing furnace for softening treatment, and an oxide layer is formed on the surfa...

Problems solved by technology

[0003] During the whole processing process, because the flat wire is formed from rough rolling, rough drawing, and then fine drawing to the finished product, the size fluctuations during rough rolling are large, resulting in subsequent processing. The surface of the copper alloy flat wire is blurred and scratched to form grooves, which affects the later stage. Plating and surface quality
