Zhangjiagang Ruijia Machinery Launches Dual-Head Dual-Saw Intelligent Puller: Redefining High-Precision Metal Profile Processing Efficiency
July 1, 2025, Zhangjiagang, China
Core Technological Innovations
Zhangjiagang Ruijia Machinery Equipment Co., Ltd. today officially unveiled its industry-disrupting product—the Fully-Servo Dual-Head Dual-Saw Intelligent Pulling System. Featuring a coordinated dual-puller + dual-saw unit architecture, this equipment achieves fully unmanned operations in pulling, sawing, and material transfer for metal profiles (tubes/bars/structural shapes) through servo constant-tension control and PG vector closed-loop technology. It sets new benchmarks for precision and efficiency in high-speed continuous production lines.
Revolutionary Technical Architecture
1. Dual-Power Coordination System
Servo Constant-Tension Pulling: Main drive utilizes high-torque servo motors to ensure consistent material tension
Dual-Car Sprocket Drive: P1/P2 pulling cars powered by precision sprocket-chain transmission with 40% longer service life and superior impact resistance
Dynamic Yielding Design: P1/P2 clamping units achieve cyclic handover through vertical staggered layout, increasing effective operational time by 100%
2. Intelligent Clamping System
Servo-Controlled Press Blade: Precise angular control of press blades via servo motors
Millisecond Response: Clamping action response time ≤0.1 sec, compatible with 120 m/min production lines
Zero-Damage Clamping: Special jaw design eliminates surface indentations
3. Military-Grade Motion Control
Control System Topology
[PG Encoder] → [Vector Control Servo Drive] ↔ [Industrial Ethernet] ↔ [Master PLC]
5-Stage Speed Profiling: Independent speed control for Pulling/Fast Return/Return1 Deceleration/Return2 Deceleration/Home Positioning
Nanoscale Positioning: ±0.05mm repeatability (via PG closed-loop feedback)
Parametric Programming: Digital preset of 20+ parameters including saw position and re-pulling length
4. Heavy-Duty Rail System
Dual-Rail Load Structure: Composite bearing system with upper square steel beam + elevator-grade lower guide rail
3D Positioning Wheel Set: Main travel wheels + side guide wheels + bottom pressure wheels create spatial constraint
Anti-Eccentric Load Design: Withstands 8-ton unilateral eccentric loads for asymmetric profile processing
Fully Automated Workflow
1. P1 Process: Clamp at profile joint → Traveling saw cut → Constant-tension pull to cooling bed discharge end
2. P2 Process: Pre-return to home → Handover clamping → Secondary sawing
3. Intelligent Cycle: Seamless cycling via vertical spatial yielding, reducing cycle time to 45 seconds
Customer Value Breakthroughs
Efficiency Doubled: 95% equipment utilization with dual-car cycling, boosting output by 130%
Cost Optimization: Preset pulling pressure reduces energy consumption by 22% and material waste
Maintenance Revolution: Modular design enables ≤30-minute critical component replacement
Quality Leap: PG vector control ensures ±0.1mm sawing length tolerance (3x beyond national standards)
"This is not just equipment upgrade, but a revolution in production logic," "Our spatiotemporal coordination algorithm solves the industry pain point of 70% idle time in traditional pullers. Combined with PG closed-loop vector control, it maintains precision equivalent to a human hair's width even at 120 m/min speeds."
