Uniwin Pulley Type Wire Drawing Machine
The pulley type wire drawing machine is a specialized piece of equipment specially used to draw 6.5 mm wires (such as steel wires, iron wires, etc.) to the target diameter, such as 5.5mm, 3.4mm, 2.8mm, etc. It plays a critical role in the nail manufacturing process. Whether producing wire nails, coil nails, D-type nails, U nails, etc., they must undergo high-precision wire drawing before forming to ensure the size consistency and strength of the nails.
Working Principle of Pulley Type Wire Drawing Machine
The common pulley type wire drawing machine uses wire drawing drums powered by the motor/reducer to pull the thick steel wire through a series of wire drawing dies with progressively smaller apertures. As the wire passes through each die, its diameter is gradually reduced while its length increases. This process is typically performed under dry drawing conditions, using wire drawing lubricant powder to reduce friction and protect the drawing dies.
Main Components
Drawing Drum (Capstan): Provides pulling force to pull wire through each drawing die with uniform speed.
Drawing Die: Made of tungsten carbide or diamond material.
Motor and Reducer: Output stable power to provide uniform drawing force for wires.
Wire Take-up Device: Automatically coils the drawn wire for processing or transportation.
Importance of Wire Drawing in Nail Production
In the nail manufacturing line, wire drawing is always the first and most important step.
Poor wire drawing quality can result in:
Inconsistent nail length and diameter
Cracked or malformed nail heads
Wire breakage or jamming during automatic nail-making machine operation
…
High-quality wire drawing ensures that the wire is suitable for high-speed nail production lines and prevents production interruptions.
If you don’t buy wire drawing machine, you need to buy drawn wires, such as 3.1mm 3.4mm 4.1,mm etc. It can feed into nail making machines directly.
Applications Beyond Nail Manufacturing
The pulley type wire drawing machines are indispensable in nail production, they are also widely used in many other metal processing industries, including:
Nail wire manufacturing
Welding wire production
Construction iron wire and binding wire production
Galvanized and stainless steel wire industries
