Introduction

The copper wire drawing machine is a vital apparatus in the manufacturing industry. It plays a significant role in producing conductive wires used in various applications, including electrical wiring and telecommunications. This article details the working mechanism of a copper wire drawing machine, breaks down its components, explains its operation, and highlights the solutions offered by Sanjin Company.

Mechanics of a Copper Wire Drawing Machine

The copper wire drawing machine functions by reducing the diameter of a copper rod through a mechanical process. The drawing process involves pulling the copper rod through a series of tungsten carbide or diamond dies, each with a successively smaller diameter. This reduction is achieved without altering the material’s volume, thus lengthening the wire proportionally.

Principles of Wire Drawing

Wire drawing is based on the principle of plastic deformation, where the copper rod is stretched beyond its elastic limit. The tension applied must overcome the yield strength of the copper. Some specific parameters include:

• Initial copper rod diameter: 8 mm
• Final wire diameter: as low as 0.02 mm
• Tensile strength maintained at approximately 300 MPa

Key Components of the Machine

A typical copper wire drawing machine comprises several critical components, each serving a specific function:

Die Box

The die box contains the series of dies through which the copper wire is drawn. Each die progressively reduces the wire diameter.

Capstan and Bull Block

These components facilitate the drawing process by pulling the wire through the dies. The capstan rotates to wind the wire, while the bull block provides additional pulling force.

Lubrication System

This system reduces friction and heat generated during the drawing process. Lubricants ensure the longevity of the dies and quality of the drawn wire.

Operation Process

The operation of a copper wire drawing machine involves several stages:

Loading

The process begins with loading the copper rod onto the machine's pay-off section.

Drawing

The copper rod is drawn through the dies. Each pass through a die results in a reduction of diameter and an increase in length.

Annealing

Annealing involves heating the drawn wire to relieve internal stresses, enhancing ductility. Common annealing temperature ranges between 300°C to 400°C.

Winding

After drawing, the wire is wound onto reels or spools for storage or transport.
