Problems solved by technology

However, this method has a long production cycle, because it is cast in one furnace, the length, weight and shape are limited, and the vacuum production cost is high and the output is small, so it is difficult to establish a continuous industrial production scale

Abstract

The invention relates to a continuous extrusion device with double right-angle channels. The continuous extrusion device comprises a second extrusion mold (35) which comprises a second extrusion cavity (36). The front side of the second extrusion cavity (36) is provided with a second feed channel (37), an upper feed pressurization channel (42), a lower feed pressurization channel (42), a left feed pressurization channel (42) and a right feed pressurization channel (42), and the rear side of the second extrusion cavity (36) is provided with a central discharge channel (38). Certain include angles are formed between the four feed pressurization channels (42) and the central line of the second extrusion cavity (36). The central discharge channel (38) is provided with the first right-angle channel (39) and the second right-angle channel (40) which are each internally provided with a plunger chip. By adoption of the continuous extrusion device, continuous production of copper-chromium-zirconium alloy contact lines is achieved, influence of the capacity of a furnace body is avoided, the copper-chromium-zirconium alloy contact lines which are of random lengths and accord with the component requirements can be produced, and the requirements of future high speed railway development can be met.

Description

technical field [0001] The invention relates to a continuous extrusion device with double right-angle channels, which is mainly used for the continuous production of large-length, high-strength, high-conductivity copper-chromium-zirconium alloy contact wires. 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 streng...
