Precision High-Strength Plate Leveling Machine | Specialized Leveling Solution for Hot-Formed Automotive Steel (Compliant with IATF 16949 Standard)
Core Process Value
This ultra-high-strength plate leveling system is specifically developed for automotive hot-forming processes, overcoming technical challenges in leveling high-strength steel with a yield strength of up to 1500 MPa. It achieves ≤0.1mm/m² flatness control precision, meeting the stringent leveling requirements for A/B pillars, crash beams, and other critical safety components.
Innovative Technological Framework
1. Four-Dimensional Reinforced Structural System
✔ Gantry Four-Column + Box-Beam Hybrid Frame Design → 60% increase in structural rigidity
✔ Patented Stress Relief Process → 98% elimination of welding residual stress
2. 21-Roller Ultra-Precision Leveling Module
✔ Rollers made of GCr15 bearing steel with gradient heat treatment (850°C vacuum quenching + deep cryogenic treatment)
✔ Micron-level hard chrome plating (50μm thickness, hardness ≥65HRC)
✔ Nano-precision grinding process, cylindricity error <2μm, surface roughness Ra0.2
3. Zero-Backlash Transmission System
✔ JIS 5-grade ground helical gear set, 85%+ gear contact pattern, transmission error ≤1.5 arcmin
✔ Universal joint full-drive mechanism, axial runout controlled within 0.01mm
4. Integrated Cast Iron Base
✔ Made of FC300 high-strength cast iron, tensile strength ≥300MPa
✔ Natural aging treatment (≥6 months) to eliminate 99% of internal stress
Intelligent Control System
✔ Servo Thickness Adjustment → Servo motor with displacement sensor for precise leveling thickness control (optional).
✔ Siemens S7-1200 PLC → Stores 50+ leveling process parameters.
✔ Industrial IoT Module → Supports OPC UA protocol for MES system integration.
