What Is a Straight Line Wire Drawing Machine?
The straight line wire drawing machine is used to continuously reduce low-carbon steel wire rod to the required finished diameter using multiple drawing dies and drawing drums. Our machine uses Φ560 mm drawing drums. Each drum is driven by an independent motor, while the PLC and frequency converters coordinate the operating speed and wire tension between different drawing blocks.
Compared with the pulley-type wire drawing machine, the straight line design provides higher drawing speed, more accurate tension control and better stability for continuous production.

Key Components and Features
- Independent Drive System
Each drawing block is driven by a 22 kW, 6-pole motor with independent frequency control. The first block uses a heavy-duty reducer for higher drawing torque, while the following blocks use belt transmission for smooth operation.
- PLC and Automatic Tension Control
The PLC, frequency converters and tension sensors automatically coordinate the speed between adjacent drawing blocks. This maintains stable wire tension, reduces wire breakage and allows each block to operate independently or as part of the complete machine.
- Water and Air Cooling System
The machine uses a combined water and air cooling system to control operating temperature during continuous drawing. This helps maintain stable production and extend the service life of the drums and drawing dies.
- Φ560 mm Drawing Drums
The Φ560 mm drawing drums are made of ZG45 cast steel with a wear-resistant surface treatment. Internal water cooling and external air cooling help control the drum temperature during continuous operation.
- Drawing Die Boxes
Each die box has separate sections for the drawing die and drawing powder. The drawing die section is water-cooled, while rotating die boxes or powder stirring devices can be supplied to improve lubrication.
- Heavy-Duty Welded Frame
The machine adopts a reinforced welded box frame with stress-relief treatment to reduce vibration during high-speed operation. Water pipes, drainage pipes and electrical cables are arranged inside the frame for a cleaner layout and easier maintenance.
How to Determine the Required Drawing Passes
The required number of drawing drums depends on the wire material, inlet diameter, outlet diameter, tensile strength and reduction per drawing pass.
A smaller diameter reduction requires fewer drums, while drawing thick wire rod to a much smaller diameter requires more drawing passes.
Please provide the following information:
Wire material
Inlet wire diameter
Finished wire diameter
Required capacity
Based on this information, we will calculate the suitable number of drawing drums, drawing die sequence, and other requirements.
Supporting Equipment for a Complete Wire Drawing Line
The LZ560 straight line wire drawing machine can be combined with different supporting equipment according to the raw wire condition and finished wire collection method.
Typical production flow:
Wire Pay-Off → Mechanical Descaling → Wire Drawing → Wire Take-Up
Optional equipment includes:
Wire pay-off stand
Mechanical descaling machine
Sharpening machine
Butt welding machine
Elephant trunk take-up machine
Hydraulic take-up machine
I-wheel take-up machine
The exact equipment combination depends on the raw wire coil, wire surface condition, finished wire diameter, production capacity and required take-up method.
Factory Testing Before Delivery
Before delivery, each machine is inspected and tested at our factory.
The inspection includes:
Individual motor operation
Drawing drum rotation
PLC and frequency converter control
Automatic tension response
Cooling water circulation
Linked operation of all drawing blocks
Emergency stop and safety protection
Frequently Asked Questions
1. Can one machine produce different wire diameters?
Yes. Different finished wire diameters can be produced by changing the drawing dies.
2. How many drawing drums do I need?
The required number depends on the inlet diameter, outlet diameter, wire material and reduction ratio of each drawing pass.
3. Can each drawing drum be controlled separately?
Yes. Each drum is equipped with an independent motor and frequency converter.
4. Can the machine draw 6.5 mm wire rod to 2.0 mm?
Yes. The drum quantity, motor power and drawing die sequence will be calculated according to your actual wire material.
5. What is the difference between LZ560 and LZ600?
The LZ560 is mainly used for low-carbon steel wire drawing, while the LZ600 is generally selected for high-carbon steel wire drawing.
6. Do you provide installation and commissioning support?
Yes. We provide machine manuals, electrical drawings, installation guidance and remote technical support. On-site installation and commissioning can also be arranged when required.
