Problems solved by technology

[0004] At present, whether it is pure aluminum or aluminum alloy, the single wire diameter of the conductor is usually above 1.0mm, and the conductor type composed of it is a second-class conductor according to the standard regulations. The single wire preparation is drawn by a larger wire drawing machine. Complete in one step, there is no precedent for aluminum or aluminum alloy conductors as flexible conductors (category five / category six) in the market

Abstract

The invention provides a manufacturing method for aluminum alloy fine wires. The manufacturing method for aluminum alloy fine wires includes the following steps of (a) the first time of drawing, wherein an aluminum alloy rod is drawn into an aluminum alloy line, and the drawing speed is 10-40 m / s; (b) the second time of drawing, the aluminum alloy line obtained from the step (a) is drawn into an aluminum alloy wire, and the drawing speed is 5-30 m / s; (c) the third time of drawing, wherein the aluminum alloy wire obtained from the step (b) is drawn into an aluminum alloy fine wire, and the drawing speed is 5-30 m / s; (d) a heat treatment process, wherein the aluminum alloy fine wire obtained from the step (c) is treated according to the process of heating-heat and preservation-cooling. By means of the manufacturing method for aluminum alloy fine wires, aluminum alloy materials can be drawn into single wires with good mechanical performance and anti-fatigue performance, and the single wires meet the requirements of fifth-class / sixth-class conductors in GB / T3956 and can be used as flexible conductors.

Description

technical field [0001] The invention relates to a method for manufacturing aluminum alloy filaments. Background technique [0002] With the rapid development of my country's economy, my country has also become the world's largest wire and cable manufacturer and consumer. Aluminum is one of the conductor materials for wires and cables. However, due to the poor toughness and fit of pure aluminum conductor materials, it is difficult to draw them to very thin by traditional drawing processes. Even if they are barely drawn successfully, their mechanical properties are difficult to meet. Therefore, in the cable conductor standard GB / T3956-2008 (equivalent to the international standard IEC60228:2004), although aluminum and aluminum alloys are one of the materials that can be used as conductors, they are only used as the first type (solid conductor) and The second type (twisted circular or twisted) conductors, these two types of conductors are only used as conductors for fixed layi...
