Technology and apparatus for manufacturing shaped conductor

Abstract

The invention relates to a shaped conductor manufacturing technique and a device thereof, wherein, the manufacturing technique comprises payingoff step, lead-forming step and lead-drawing step and is characterized in that the lead-forming step adopts the technique of combing drawing and rolling; the section of a lead is shaped by rolling; the sectional area of the lead meets requirement by drawing; the device comprises a payingoff device, a shaped conductor forming device and a lead-drawing device which are sequentially arranged, wherein, the shaped conductor forming device is provided with a shaped groove roller device. The technique ensure the quality of products, greatly improves producing efficiency and meets the production requirement of compound carbon fiber aluminum stranded conductors required by ultra-high and super-high power transmission.

Description

technical field [0001] The invention relates to a wire and cable manufacturing process and its processing equipment, in particular to a manufacturing process of copper, aluminum and aluminum alloy materials with special-shaped cross-section wires and its stretching and rolling units. Background technique [0002] The steel-cored aluminum stranded wires used in ultra-high voltage and ultra-high voltage transmission cables use multi-strand steel wire twisted steel cables for their steel cores, which are heavy and cause large line sags. The tower distance cannot be increased and it occupies a lot of land. The aluminum stranded cable made of composite carbon fiber core instead of steel core saves 30% of steel core compared with steel core aluminum stranded wire, and has high strength, high corrosion resistance, creep resistance and other comprehensive properties, and its cost is low, light weight, It is a product that saves energy, materials, and land (saving power transmission ...

Problems solved by technology

[0005] However, the process of manufacturing wires with special-shaped cross-sections is very difficult, and the drawing process cannot be used. Even if the circular drawing die is replaced with a special-shaped drawing die, the corrugation angle of the wire after drawing is not full, the cross-sectional shape is not qualified, and the wire cannot be reached. technical standards

At present, the extrusion process is used to manufacture wires with special-shaped cross-sections at home and abroad, and they are pressed by metal extruders. The disadvantage is that the metal extruder is not a special production equipment for wires and cables, but an alternative equipment. Its outgoing speed is very low and cannot be equipped. The automatic wire take-up machine can only take up the wire with a single reel, and the take-up efficiency is low. It must be stopped when the reel is manually changed after the wire is taken up. The assembly line cannot be matched with the existing wire and cable assembly line

In particular, the extruder cannot control the turning and twisting of the wire, and the product quality is unstable
