The core advantages of modern steel strand equipment (including wire drawing, stranding, stabilization, cutting, etc.) are concentrated in six aspects: high precision, high efficiency, high stability, intelligence, low loss, and strong adaptability, which can significantly improve product quality and production efficiency.
I. High Production Efficiency and Large Capacity
High-Speed and Stable Operation: The wire drawing machine is designed for a speed of up to 10 m/s, with a normal operating speed of 3–10 m/s for Φ5mm steel wire. A single machine can produce over 55 tons per day.
High Stranding Speed: The intelligent stranding machine can achieve a stranding speed of up to 120 meters per minute, significantly improving stranding efficiency.
Continuous Production: Integrates the entire process of wire feeding, drawing, stranding, stabilization, and take-up, reducing intermediate transfer and downtime.
II. Controllable Product Precision and Quality
High Dimensional Accuracy: Die hole coaxiality ≤0.02mm, pulley runout <0.01mm, and extremely small wire diameter tolerance.
Stable Strength: Precise control of drawing compression rate (total compression rate ≥93%, adjustable from 13% to 25% per pass), achieving a strength of up to 2300 MPa for Φ5mm steel wire and 2160 MPa for Φ7mm wire after drawing.
Uniform tension: Multi-axis servo synchronous control ensures tension fluctuation ≤ ±1.5%, guaranteeing uniform strand pitch, compact structure, and no loose strands in the steel strands.
High surface quality: Staged cooling (water cooling + air cooling) and precise lubrication reduce surface scratches and oxidation, resulting in a high-gloss finish on the finished product.
III. High Equipment Stability and Reliability
Highly Efficient Power Transmission: Variable frequency motor + high-strength belt + hardened gearbox ensures smooth power transmission and a low failure rate.
Comprehensive Cooling System: Drum-type circulating water cooling + independent air cooling, and powerful mold cooling solve the problem of high temperatures during drawing, ensuring long-term full-load operation.
Durable Key Components: Molds, drums, etc., are made of wear-resistant alloys, resulting in a long service life (e.g., key components of the screw press have a lifespan of over 8000 hours).
Comprehensive Protection Mechanisms: Hydraulic overload protection, emergency braking, and automatic shutdown in case of failure reduce the risk of equipment damage.
IV. High Degree of Intelligence and Automation
Intelligent Control System: PLC + touchscreen, one-click parameter setting, real-time monitoring, and automatic alarm.
Remote Operation and Maintenance: Supports remote diagnostics, fault warnings, and maintenance reminders, reducing on-site maintenance costs.
Automatic Adjustment: Automatically adjusts tension, temperature, and lubrication based on wire diameter and speed, reducing manual intervention.
Data Acquisition and Traceability: Real-time recording of production data facilitates quality traceability and process optimization.
V. Wide Material Adaptability and High Flexibility
Comprehensive Specification Coverage: Inlet diameter up to Φ16mm, outlet diameter Φ4–Φ9mm; capable of producing various structures such as 1×7 and 1×19, with steel strand diameters of 9.15–21.6mm.
Good Material Adaptability: Compatible with high-carbon steel wire rods with a carbon content of **0.77%–0.97%**, tensile strength ≤1550MPa.
Quick Changeover: Modular design, short die changeover time (e.g., extruder die changeover ≤10 minutes), suitable for multi-variety, small-batch production.
VI. Low Energy Consumption, Low Loss, and Cost-Effective
Energy-Saving Design: Variable frequency drive and high-efficiency motor, saving 15%–30% more electricity than traditional equipment.
Low Die Loss: Precise tension and lubrication control extends die life and reduces consumable costs.
High Yield: Low breakage rate and low scrap rate, with an overall yield rate of over 98%.
Low Labor Costs: High degree of automation reduces the need for operators and inspectors.
VII. Advantages of Construction Supporting Equipment (Cutting/Threading/Extrusion)
Steel Strand Shearing Machine: Cold shearing eliminates high-temperature damage, producing clean, burr-free cuts; high efficiency and safety.
Threading Machine: Achieves a 99.2% success rate in threading cables through complex curved ducts, reducing rework.
Extrusion Machine: High extrusion force (up to 500 tons), low slippage rate, and reliable anchoring quality.
