High Speed Dual Line Metal Palisade Fence Roll Forming Machine

High Speed Dual Line Metal Palisade Fence Roll Forming Machine：

Dual-Line High-Efficiency Architecture & Heavy-Duty Frame Rigidity

The XINNUO High Speed Dual Line Metal Palisade Fence Roll Forming Machine represents a high-productivity technological breakthrough in the cold roll forming equipment sector. Engineered specifically for commercial, residential, and agricultural security fencing manufacturers, this advanced production line features a dual-strand parallel forming structure integrated onto a single, heavy-duty machine chassis. By processing two independent metal strips simultaneously on parallel forming stations, the machine doubles production throughput without doubling workshop footprint or energy consumption. The robust machine base is fabricated from heavy-duty 350H/400H structural steel beams, thermally stress-relieved and precision-milled to eliminate internal stresses and vibration during continuous high-speed roll forming. The solid middle-plate side wall stands provide superior torsional stability, ensuring microscopic alignment and profile consistency across both production channels.

Synchronized Precision Roll Tooling & Solid Shaft Engineering

Each forming station on the dual-channel line utilizes precision-machined forming rollers manufactured from premium 45# forged carbon steel or high-grade GCr15 bearing steel. The roller surfaces undergo high-precision CNC multi-axis turning, vacuum induction quenching to HRC 58-62, and a 0.05 mm hard chrome electroplating treatment to deliver superior abrasion resistance and scratch-free surface protection for delicate pre-painted (PPGI) and galvanized coils. The dual roller sets are mounted on high-strength solid shafts precision-turned from 40Cr alloy structural steel. Each shaft is subjected to high-frequency tempering and cylindrical grinding to ensure absolute concentricity under dynamic torsional loads. Driven by an energy-efficient geared motor combined with heavy-duty industrial roller chains and precision sprockets, power is smoothly and synchronously distributed across all progressive forming stations.

Twin Independent Hydraulic Cut-Off Units & Profile Versatility

To match the high output velocity of the dual-line forming stations, the machine is equipped with twin independent high-tonnage hydraulic cutting heads positioned side by side at the line exit. Each cut-off station features custom-contoured shear blades machined from high-carbon, high-chromium Cr12MoV die steel, vacuum heat-treated to HRC 60-62 for clean, burr-free, and deformation-free cut edges. The dual hydraulic cylinders are powered by a centralized hydraulic pumping station equipped with integrated cooling fans, electromagnetic solenoid valves, and precision pressure regulators. The tooling design supports various popular fence picket geometries, including classic W-profile palisade slats, D-profile security pales, corrugated fence panels, and flat-top picket profiles with custom punching options for quick on-site fastener assembly.

Intelligent Industrial PLC Synchronization & Global After-Sales Assurance

The entire dual-line manufacturing process is orchestrated by a centralized industrial PLC automation system paired with an intuitive multi-language color touchscreen human-machine interface (HMI). Operators can independently or synchronously set batch counts, target cut lengths, and operating speeds for each line. High-precision optical rotary encoders monitor strip displacement in real time, achieving continuous length cutting accuracy within ±1.0 mm. Manufactured strictly under ISO9001 quality management protocols and compliant with European CE safety standards, every XINNUO roll forming machine undergoes exhaustive 72-hour factory testing under full electrical load before overseas shipment. Backed by comprehensive technical manuals, remote diagnostic support, lifetime engineering consultation, and global spare parts dispatch, XINNUO provides metal fence fabricators worldwide with dependable, high-yield manufacturing equipment.
