Problems solved by technology

The existing copper-clad steel or copper-steel composite contact wire simply increases the pressure, pressure or cold rolling, so that the copper and steel have a large amount of deformation, so that the copper and steel are composited together, and the process is simple. Due to the mismatch of expansion coefficients, the phenomenon of copper and steel detachment will cause safety hazards

Abstract

The invention relates to production equipment and method for a mortise and tenon type high-strength and high-conductivity copper-steel composite contact line. The production equipment for the copper-steel composite contact line comprises a first die, a steel rod pipeline, a second die, a continuous cold forging device and an arrangement die which are arranged in sequence. The first mold comprises an injection section and a cooling section, the injection section is provided with a copper cavity, molten copper isolated from air is injected into the copper cavity, and an inlet is formed between the injection section and the cooling section and communicated with a steel rod pipeline; the cooling section is provided with a cooling circulation system, materials enter the second die after being cooled into a solid state through the circulation cooling system, and a continuous cold forging device and an arrangement die are sequentially arranged on the second die. The copper layer and the steel layer of the contact wire are connected and fixed by adopting the mortise and tenon structure, the disengagement caused by linear expansion factors of copper and steel in the transverse direction is overcome, and in the longitudinal direction, as the periphery of the mortise and tenon steel rod table is filled with the copper, the riveting of the copper and the steel is enhanced, so that the copper and the steel are completely riveted together.

Description

technical field [0001] The invention relates to the field of wire materials, in particular to a production equipment and method for a mortise and tenon type high-strength and high-conductivity copper-steel composite contact wire. Background technique [0002] With the development of electronic information technology, the requirements for the comprehensive performance of copper alloy conductive materials are getting higher and higher. It is required to maintain high electrical conductivity and thermal conductivity while maintaining high strength (hardness), toughness, and wear resistance. Sex, cold resistance, non-ferromagnetic and other characteristics. These excellent properties make copper alloys gradually become important metal materials used in high-tech fields such as electric power, information, transportation, energy, light industry and aerospace. In many occasions, it is rarely used in the form of pure copper. This is because the strength of pure copper is low (230-...
