Copper Rod Breakdown Drawing Machine

1. General description:

Copper rod breakdown machine is a specialized piece of equipment used in the wire and cable manufacturing industry. Its primary function is to reduce the diameter of copper rods or other metal rods to produce wires of smaller diameters. This process is known as wire drawing or wire drawing breakdown.
 
Here's a breakdown of how a copper rod breakdown machine typically works:
Feeding: Copper rods, usually produced through processes like casting or extrusion, are fed into the machine. These rods are often in the form of coils or straight lengths.
 
Drawing Dies: The rods pass through a series of drawing dies, which are usually made of tungsten carbide or diamond. These dies have progressively smaller diameters, and as the rods are pulled through them, they are elongated and reduced in diameter. This reduction in diameter is achieved through the application of pulling force exerted by a capstan or similar mechanism.
 
Cooling and Lubrication: To reduce friction and heat generated during the drawing process, the rods may be cooled and lubricated. Cooling can be achieved through water or air cooling systems, while lubrication helps reduce wear on the dies and improves the quality of the drawn wire.
Multiple Passes: Depending on the desired final diameter of the wire, the process may involve multiple passes through different sets of drawing dies, each with slightly smaller diameters. This allows for precise control over the wire diameter and ensures uniformity.
 
Final Product: The result is a copper wire of the desired diameter. This wire can then be further processed if necessary, such as annealing to relieve stresses, or it can be wound onto spools for storage and distribution.
 
Copper rod breakdown machines are essential in the production of various types of wires used in electrical applications, telecommunications, construction, and many other industries where conductive wire is required. The efficiency and precision of these machines play a crucial role in determining the quality and reliability of the final wire products.

3. Brier introduction:
3.1 Payoff stand:
Type: cantilever type
Payoff stand consists of column, cantilever and steering roller.
Height of the column is 5000mm or so. The two aluminum reels can achieve continuous pay off.
3.2 Main drawing machine:
Type: slip type. 13-die copper wire drawing machine with drawing blocks of the same diameter
The machine consists of trough for cooling and circulation of drawing emulsion, gearbox, lubrication system, constant speed wheel, main motor and the motor for the constant speed wheel.
Four clip-and-run switches for die stringing by clip-and-run operation. Device to prevent the drawing block and drawing die holder extend identical distance from the body of gearbox.
Drawing blocks adopt steel wheels. Its surface is covered by tungsten carbide to prolong its use life.
