Earthquake Resistance Shear Wall Production Line

Core Functions and Technical Features:

1) Integrated Composite Section Forming

Main Wall Panel: High-strength steel plate (Q550GJ/Q690) with a thickness of 2.0-8.0 mm and a tensile strength of ≥650 MPa.

Vertical Stiffeners: Cold-bent into T-shaped or U-shaped ribs (80-200 mm in height) to enhance the wall's buckling resistance.

Horizontal Shear Strips: Roll-formed transverse corrugations (150-300 mm in length) to enhance energy dissipation. https://example.com/spsw-profile.png (Schematic diagram: Steel plate shear wall composite structure)

2) Optimized seismic performance design

Preset "weak beam, strong wall" bending lines on the rollers guide the directional release of seismic energy (meeting earthquake resistance requirements of magnitude 8).

Intelligent adjustment of stiffener spacing (300-600mm) prevents out-of-plane wall instability.

3) Efficient digital production

Direct BIM data drive: Directly analyzes building model data and automatically adjusts profile dimensions (adapting to varying floor heights).

Online laser thickness measurement + machine vision positioning ensures hole group position accuracy of ±0.3mm (meeting the requirements for high-strength bolt connections).

Core equipment system components:

Heavy-duty decoiler: Hydraulic expansion bearings can carry 20-30 tons of steel coils (1.0-1.5m wide), with servo tension control to prevent deformation.

Nine-roller high-pressure leveling machine: Eliminates internal stress in 12mm thick plates, achieving a straightness of ≤1mm/㎡ (laser calibration).

High-Precision Punching Unit: 2000-ton hydraulic punching machine: Simultaneously punches bolt holes and pipeline penetration holes, supporting punching of 50mm thick plates.

Stiffener Forming Machine: 24-32 sets of carbide rollers (hardness HRC62), step-by-step pressing of T/U-shaped ribs (depth tolerance ±0.2mm).

Shear Strip Corrugation Machine: Servo frequency conversion produces horizontal corrugations with adjustable wavelength (150/200/300mm) and a wave-depth ratio of 1:8 to 1:10.

Border Locking Bending: Four-cylinder synchronous hydraulic bending machine forms wall joints (bending angle 90° ±0.5°).

Fixed-Length Plasma Cutting: Underwater plasma cutting (thickness ≤ 12mm), cut angle ≤ 3°, no thermal deformation.

3D Scanning Quality Inspection: Laser scanning compares BIM models to generate full-scale deviation contour maps (accuracy 0.1mm).

Digital Twin Control System: Real-time mapping of physical equipment status, predicting roll wear and automatically compensating for it.

Industry Application Value:

Super-high-rise buildings: Weight reduced by 60%, increasing core construction speed by three times (Shanghai Tower application case).

Industrial Seismic Resistance: Lateral stiffness of chemical and nuclear power plants increased by 200%, meeting SL-2 earthquake conditions.

Green Transformation: Carbon reduction of 1.2 tons per square meter, earning LEED certification points.
