A kind of production technology of copper braided wire

Abstract

The invention discloses a production technology of a copper braided wire. The production technology comprises the step of arranging a pay-off stand: bobbin copper wires are fixed on the pay-off stand,the bobbin is released and the copper wire connector penetrates through a sliding wheel; the step of wire scutching: the copper wires are pulled out of the pay-off stand to be wound on a spindle for3-4 circles in a clockwise way, all the copper wires are adjusted to be on the same plane and consistent in degree of tightness and wire scutching is performed; the step of arranging the spindle: thespindle after processing of the step of wire scutching is arranged on a braiding machine, the copper wires penetrate through the middle of the spindle to be pulled to a driving wheel and then compressed by a rolling wheel in the middle of the driving wheel; the step of gear adjustment: the power is disconnected and the size and the tooth space of the gear are adjusted; the step of braiding: the braiding machine is started to perform braiding, and the thickness, the uniformity and the appearance of the braided wire are inspected; and the step of wire leading: the braided copper braided wire isled to a rubber roller to perform coiling. With application of the production technology of the copper braided wire, the phenomenon of wire fracturing is not liable to occur in the production process,and the copper braided wire obtained through braiding is uniform without the situation of burrs or wire fracturing.

Description

technical field [0001] The invention relates to the technical field of mechanical structures of electrical equipment, in particular to a production process of copper braided wires. Background technique [0002] Copper braided wire is mainly used for live movement in non-horizontal direction and as a power accessory in medium and low voltage circuit breakers. [0003] The current copper braided wire generally adopts high-quality round copper wire (0.10, 0.15, 0.20 in diameter) or tinned soft round copper wire (0.10, 0.15 in diameter) with multiple strands (such as 8.12.24.36.48 ingots) through a single layer or Braided in multiple layers, the DC resistivity (20°C) of the braided wire is not greater than 0.022Ω.mm 2 / m, the DC resistivity (20°C) of the tinned copper braided wire is not greater than 0.0234Ω.mm 2 / m. [0004] Copper braided wires and multi-strand copper wires can be ultrasonically welded, but they cannot be tinned, as tinning will affect ultrasonic welding. ...

AI Technical Summary

Problems solved by technology

In this way, due to the different pressure of the pressing process and the cross-sectional area of ​​the pressed copper braided wire, some connecting terminals are not pressed properly, and the problem of heating at the connecting end will occur during use, causing safety hazards.

At the same time, if the suppression is unsuccessful, the copper braids and copper plates will no longer be usable, which will lead to a low yield and a great waste
