Pressing-like special-shaped wire stranded conductor single-wire drawing die, conductor and processing method

Abstract

The invention relates to a pressing-like special-shaped wire stranded conductor single-wire drawing die, a conductor and a processing method. The die comprises a die body, the die body is a cylinder structure, and a fan-shaped through hole is formed in the middle of the die body; the fan-shaped through hole comprises an inlet section, a compression section and a sizing section; and an included angle between the junction of the compression section and the sizing section and the horizontal direction is 30-31.5 degrees. The included angle formed by the junction of the compression section and the sizing section and the horizontal direction ranges from 30 degrees to 31.5 degrees, the copper wire can be well prevented from being broken in the drawing process, the production efficiency is improved, the four end corners, close to the compression section, of the sizing section are provided with fillets, the situation that the appearance is smooth without burrs when a conductor is stranded is avoided, cable insulation does not have a skin effect to cause breakdown, the stranded conductor obtained by drawing is less in material consumption, wire breakage is not easy to occur in the drawing process, and the production efficiency is not influenced.

Description

technical field [0001] The invention relates to a conductor drawing die, and more specifically refers to a single-wire drawing die, a conductor and a processing method for a similar tightly pressed special-shaped wire stranded conductor. Background technique [0002] A conductor is a substance that has a low resistivity and is easy to conduct electric current. Most of the existing conductors are stranded conductors, such as figure 1 as well as figure 2 As shown, the traditional stranded conductor is formed by twisting circular single wires. There are gaps between single wires, between twisted layers and twisted layers, and the shape of the twisted conductor, and the outer diameter is also large. When the traditional stranded conductor is drawn by a special drawing die, there is a disconnection during the drawing process, which affects the production efficiency, and more materials are consumed to form the stranded conductor. [0003] Therefore, it is necessary to design a...
