Core Functions and Technical Features:
Diverse Cross-Section Adaptability
Solar Rail: C/U-shaped with slots, used to secure photovoltaic panel clamps.
Purlin: Z-shaped or Σ-shaped, bearing the main structural load.
Ground Screw Sleeve: Square or round tube with connection holes, used to anchor the ground rack. https://example.com/pv-profile-types.png (Diagram: Common PV Rack Profiles)
High-Strength, Lightweight Design
Material Thickness: 0.8-3.0mm (2.0mm for aluminum alloy, 1.5-3.0mm for steel).
Tensile Strength: 550MPa high-strength steel (e.g., S550GD+AZ150) or 6061-T6 aluminum alloy.
30% weight reduction after forming compared to hot-rolled profiles, reducing transportation and installation costs.
Corrosion-Resistant Process Guarantee
Mirror-polished rollers (Ra ≤ 0.4μm) + minimal lubrication to protect the aluminum-magnesium-zinc coating (≥ 150g/m² AZ150).
Dynamic roll gap compensation prevents surface scratches.
Intelligent and Flexible Production
Quick Die Change System: Replace a full set of rollers in ≤ 30 minutes, switching between different cross-sections (e.g., C-type to Z-type).
Servo variable cross-section technology: A single production line can produce profiles with varying lengths (such as trapezoidal guide rails for slopes).
Core Equipment Components:
Double-head decoiler: Automatically switches coils, supports mixed production of aluminum and steel coils, and features EPC (Electronic Process Control) correction.
High-precision straightening machine: 9-11 rollers level the coils, eliminating yield stress and achieving a straightness of ≤0.5mm/m.
Forming mainframe: 16-24 sets of carbide rollers (SKD11 material), divided into three stages:
• Pre-punching → Cold roll forming → Sizing and calibration
Online punching/notching unit: A servo-hydraulic system simultaneously punches connection holes, drain holes, and grounding mark holes with a hole position accuracy of ±0.2mm.
Servo tracking cutting: Flying saw/laser cutting (specially for aluminum alloys) ensures burr-free cuts with a length tolerance of ±0.3mm.
Automatic palletizing robot: Stacks sections by profile type and is equipped with anti-scratch suction cups (with surface coating).
Intelligent control system: integrated with MES system, real-time monitoring of energy consumption/yield rate, and support for remote diagnosis.
