Introduction to Trapezoidal Single-Layer Plate Rolling Machine (1200mm Feeding Width, 980mm Effective Width)
Overview
The trapezoidal single-layer plate rolling machine is a specialized equipment designed for metal sheet forming, capable of rolling metal sheets (e.g., carbon steel, stainless steel, aluminum) into trapezoidal cross-sections or specific curved profiles. The designation "1200mm feeding width" refers to its maximum material input width, while "980mm effective width" indicates the stable forming width range during processing. This machine is widely used in construction, shipbuilding, automotive manufacturing, ventilation duct production, and other industries, particularly for creating trapezoidal-section components such as air ducts, structural supports, or custom metal parts.
Core Structure and Features
1. Feeding System
Maximum Feeding Width: 1200mm, compatible with metal sheets ≤1200mm wide (thickness typically 0.5-3mm, depending on material strength).
Guiding Mechanism**: Adjustable guide rollers ensure centered feeding, minimizing alignment errors and maintaining an effective forming width of 980mm.
2. Roll Forming Unit
Roller Configuration: Utilizes a 3- or 4-roller setup (upper roller as the driving roller, lower rollers as driven rollers). The rollers are designed with trapezoidal grooves or custom profiles to gradually shape flat sheets into trapezoidal cross-sections.
Roller Material: High-carbon or alloy steel with surface hardening for enhanced wear resistance and longevity.
Adjustment System: Hydraulic or mechanical controls for precise roller spacing and pressure adjustments to accommodate varying sheet thicknesses.
3. Drive and Control System
Motor Power: Typically 5.5-15kW (varies with material thickness and processing speed), paired with a gear reducer for stable torque output.
Control Interface: PLC + touchscreen for parameter presets (e.g., feed speed, rolling angle, forming cycles) and manual/automatic mode switching.
4. Output and Auxiliary Components
Support Frame: Stabilizes formed workpieces to prevent deformation.
Safety Features: Emergency stop buttons, photoelectric sensors, and guards to ensure operator safety.
Workflow
1. Sheet Preparation: Cut metal sheets to ≤1200mm width and load onto the feeding table.
2. Parameter Setup: Input sheet thickness, target trapezoidal angle, and forming length via the control panel.
3. Centered Feeding: Activate guide rollers to align the sheet along the central axis.
4. Roll Forming: Gradually press the sheet through multiple rollers to achieve the trapezoidal profile.
5. Output and Shaping: Support the formed workpiece on the output rack for cutting or stacking.
Applications
Construction: Ventilation ducts, roof drainage channels with trapezoidal sections.
Industrial Equipment: Machine guards, conveyor belt supports.
Transportation: Vehicle underbody panels, reinforced cabin structures.
Custom Fabrication: Small-batch production of specialized metal components.
