Pulley Type Wire Drawing Machine for Medium Carbon Steel Wire Production

The DAPU pulley-type wire drawing machine is specifically designed for stable drawing of medium-diameter wire. This equipment can withstand complex and harsh environments, providing steel mills with reliable drawing performance and long-term stable production.

This machine is a type of dry wire drawing machine that can draw carbon steel wire, galvanized steel wire, and construction steel wire, with a maximum wire diameter of 6.5 mm and a minimum drawing diameter of 2 mm.

This robustly constructed and easily maintained machine requires a low initial investment, making it an ideal choice for small and medium-sized factories.

The pulley wire drawing machine employs mechanical transmission and an external lubrication system. The wire diameter is reduced by passing through a series of rotating pulleys. This working principle makes the equipment more suitable for drawing medium-diameter steel wires.

Due to its simple mechanical structure, ease of maintenance, and low investment cost, it allows for quick die changes and maintenance of other parts, reducing downtime and providing efficient and economical wire drawing.

The pulley-type wire drawing machine employs dry drawing technology, using a lubricant (drawing powder or soap) instead of a fully enclosed water-cooled tank. It features stable drawing, ease of operation, and rapid production, making it particularly suitable for producing medium-diameter wires.

1. Wire feeding system:

The coil is placed on the wire feeder, smoothly unfolded, and fed into the first drawing process.

2. Multi-stage Pulley Diameter Reduction

The wire passes through a series of drawing dies, gradually reducing its diameter.

3. Mechanical Transmission

The equipment is driven by a motor, which is connected to multiple pulley blocks via belts or gearboxes, enabling continuous dry drawing production.

4. Tension Balancing

Controlling the drawing speed and balancing the tension prevents wire breakage, die wear, and surface scratches—crucial for medium carbon steel wire.

5. Cable Collection

The last block collects the cable and outputs it as a coil for easy subsequent processing.

The pulley type wire drawing machine is widely used for medium-diameter dry wire drawing production, especially in construction and general steel wire processing industries. Below are its main application areas:

1. Galvanized Wire Production
The pulley-type wire drawing machine first draws the wire to the required diameter, and then hot-dip galvanizes or electro-galvanizes it. This ensures uniform wire diameter and consistent zinc coating thickness. It is ideal for producing galvanized iron wire for fencing, binding, and agricultural applications.

2. Construction Binding Wire
This machine is ideal for producing construction binding wire (tying wire) for rebar fixing and reinforcement projects. The dry drawing system gives the wire good tensile strength and surface quality, ensuring that the wire retains its flexibility and strength after annealing. It is the best choice for high-volume binding wire production lines.

3. Fence Wire
For chain-link fence wire, barbed wire core wire and agricultural fence wire, the pulley wire drawing machine can stably produce steel wire with uniform wire diameter. The steel wire will not break during the continuous production process, ensuring the high quality of the fence produced.

4. Mesh Wire
Pulley wire drawing machines are widely used in the production of wire for welded and woven wire mesh. Precise diameter reduction ensures the dimensional accuracy of the mesh. It is particularly suitable for the production of construction and industrial mesh.

5. Annealed Wire
Before the wire enters the annealing furnace, a pulley wire drawing machine reduces the wire diameter. The dry drawing process helps reduce surface scaling. After annealing, the wire becomes soft and flexible, suitable for binding and packaging applications.

When selecting between pulley type and water tank wire drawing machines, the decision mainly depends on wire diameter range, production speed, cooling requirements, and investment budget.

How to Choose?

If you primarily process medium-diameter wires, require low investment, and are easy to operate, choose a pulley-type wire drawing machine.
If you focus on fine wire production, high output, and high-quality wire surface finish, choose a water tank-type wire drawing machine.

Robust Mechanical Structure
The DAPU pulley-type wire drawing machine is constructed of heavy-duty steel and can continuously draw low-carbon steel wire. Vibration-damping technology is incorporated into the pulley blocks and transmission components, effectively extending the machine’s lifespan.

Easy Maintenance
The simple structure allows for quick and easy replacement of wear parts, reducing downtime.

Low Investment Cost
Compared to high-speed straight-feed wire drawing machines and water tank-type wire drawing machines, pulley-type wire drawing machines require a lower initial investment.

Flexible Pulley Block Configuration
The number of wire drawing pulley blocks can be customized according to the required inlet and outlet wire diameters, enabling high production flexibility.

Suitable for Galvanized Wire
The stable dry wire drawing process ensures uniform wire diameter before galvanizing, improving the consistency of the galvanized layer. It is particularly suitable for producing galvanized iron wire for fencing, binding wire, and construction applications.
