Designed specifically for 960-1100MPa materials (Q345, Q420, HG785). Dual-motor pressure-reduction system handles extreme elastic springback. Non-parallel roller arrangement with adjustable edge rollers compensates for material hardness variation.
Two independent motors drive pressure-reduction via independent worm-gear reducers. Simultaneous motor operation achieves parallel beam descent; independent motor operation enables asymmetric tilt. Resolves thick-plate loading difficulty and elastic recovery challenges.
Automatic roller count adjustment per plate thickness. Thin plates (3-8mm) activate all rollers for precision; thick plates (40-60mm) reduce roller count to increase support span. Extends equipment service life while optimizing energy consumption.
Upper and lower edge rollers independently adjustable via proportional cylinders. Eliminates edge-wave defects common in traditional equipment. Creates uniform stress distribution across full plate width.
Two independent electric motors drive main roller system through dual-input planetary reducers. Eliminates torque ripple, improves transmission efficiency, reduces noise. Ideal for continuous heavy-equipment production.
PLC system stores 500+ engineering-machinery component profiles. Operator selects component type; machine automatically calculates pressure curve, roller configuration, tilt angle. Setup time <5 minutes vs. traditional 45 minutes manual adjustment.
Two 5.5-7.5 kW motors drive independent worm-gear reducers. Synchronized operation: both motors lift cross-beam smoothly (pressure reduction). Asynchronous operation: motors lift/lower independently, enabling cross-beam tilt (±7mm angular adjustment) for single-side wave correction.
Hydraulic cylinders control individual roller engagement. Thin-plate mode: all 13 rollers active (maximum precision). Thick-plate mode: 9 rollers active (increased span, reduced bending moments). Automatic mode-switching based on incoming plate thickness measurement.
Two independent 45-75 kW motors (model dependent) coupled to main roller system via planetary reducers + flow divider valve. Each motor powers subset of working rollers. Eliminates traditional cross-shaft, reducing torque ripple from ±8% to <±1%.
Database stores 500+ component profiles pre-programmed by engineering team. Operator selects component on HMI; system automatically sets inlet/outlet pressure, roller engagement pattern, tilt angle, and cross-beam descent speed.
Upper and lower edge rollers independently adjustable via proportional hydraulic cylinders. Creates asymmetric pressure field targeting specific defect patterns: single-side edge wave, center-wave, or combination defects with automatic tilt + edge adjustment.
Q345 high-strength structural steel, closed-box welded construction, fully stress-relieved. Rigidity deflection <0.8mm under maximum composite bending load. Integrated elastomer pads reduce vibration.

Flatness tolerance improved from ±2.5mm to ±0.8mm/m²; throughput +30%; downtime reduced 35%.
Variable systems activate 9 rollers for thick plates (reduced cycling, extended bearing life) and 13 rollers for thin plates (increased precision). Fixed 13-roller equipment runs all rollers regardless of plate thickness, causing unnecessary wear on thick-plate production.
Two independent motors enable synchronized descent (both motors up = parallel beam rise) or asynchronous movement (motors independent = beam tilt for wave correction). Single-motor systems can only do parallel adjustment, limiting wave-correction capability.
Yes. Database stores 500+ component profiles. Operator selects component type on HMI; machine automatically loads all parameters (pressure curve, roller configuration, tilt angle). Changeover <5 minutes vs. 45 minutes manual setup.
500 operating hours recommended (typically 2-3 weeks at continuous operation). Service includes: hydraulic oil change, bearing re-lubrication, pressure valve calibration, seal inspection. Full PM requires 12-16 hours.
