Cable Tray Cold Bending Forming Machine

Cable tray cold bending forming machines are automated systems that transform metal sheets into precise cable tray profiles using progressive cold bending technology.Overview

Cable tray cold bending forming machines are specialized equipment designed to manufacture various types of cable trays, including ladder, perforated, U-shaped, and C-shaped trays, from metal sheets such as galvanized steel, stainless steel, or aluminum . These machines operate using cold bending technology, where metal sheets are gradually shaped through multiple roller passes without heating, ensuring high dimensional accuracy and structural integrity .

Working Principle

1. Uncoiling and Leveling: Coiled metal sheets are unrolled and flattened using a leveling machine to remove internal stresses and achieve a smooth surface .
2. Servo Feeding and Punching: High-precision servo motors feed the flat sheets into punching stations for holes such as connection, grounding, or ventilation holes .
3. Cold Bending/Forming: The sheets pass through a series of rollers in a multi-frame forming unit. Each roller gradually bends the sheet into the desired cross-sectional profile, maintaining precise angles and dimensions .
4. Cutting and Discharge: After forming, hydraulic or mechanical cutting units trim the trays to preset lengths, and the finished products are collected automatically .

Technical Specifications

• Tray Widths: Typically 100mm to 1000mm, customizable based on client requirements .
• Material Thickness: 0.8mm to 3mm for most machines .
• Production Speed: 10–20 meters per minute depending on tray type and material thickness .
• Automation: Fully automated with PLC and HMI control, requiring minimal operators (1–2 personnel), .
• Forming System: Double-sided or multi-frame roller systems allow symmetrical or asymmetrical tray profiles .
• Punching/Cutting: Integrated punching units for holes and hydraulic/flying saws for precise cutting .

Applications

These machines are widely used in industrial plants, construction projects, energy storage, photovoltaic power stations, and automated production lines. They enable high-volume, consistent, and precise production of cable trays for electrical wiring and cable management systems .

Advantages
