Product Description

 

Automatic Trapezoidal Roof Panel Roll Forming Production Line

I. Product Overview

This production line is a fully automatic cold bending roll forming equipment specially designed for the steel structure building roof system. It can process metal coils such as galvanized steel coils,
color-coated steel coils (PPGI/PPGL), and aluminum-magnesium-manganese coils into high-rigidity trapezoidal roof panels in one go through continuous progressive roll bending and precise
fixed-length cutting. The whole line integrates six processes: uncoiling, leveling, feeding, roll forming, cutting and discharging, which can operate automatically with one key. It features high forming
precision, fast production speed and stable plate performance, making it the core equipment for the production of roof panels in industrial plants, warehouses, venues, residences and other buildings.
 

II. Core Advantages

High-Precision Forming

16–24 sets of progressive forming workstations, adopting GCr15/GCr12MoV bearing-grade forged steel rolls, which are precision ground, quenched and chrome-plated (hardness HRC58–62). The plate section is uniform, the surface is scratch-free, and the tolerance is controlled within ±1 mm.

High Efficiency and Stability

The whole machine adopts H-beam welded frame + thickened wall plate, with strong rigidity and small operation vibration; 5.5–7.5 kW main motor + 4 kW hydraulic system, the production speed is adjustable from 10–60 m/min, and the daily output can reach 10,000 meters.

Intelligent Control

Standard configuration: Siemens/Delta PLC + color touch screen, supporting length preset, counting, fault self-diagnosis and one-key start-stop; hydraulic flying shear/fixed-length cutting, with flat cut and no burrs.

Durability and Low Consumption

Automatic centralized lubrication system, air cooling and full protection safety design; the service life of key components exceeds 15 years, with simple maintenance and low failure rate.

Flexible Adaptability

Compatible with 0.3–1.0 mm plate thickness and 600–1250 mm feeding width; can be customized with mainstream trapezoidal types such as TR4/5/6, 840/900/1050.

III. Standard Configuration

  • Main machine (forming frame + transmission)
  • Hydraulic cutting system
  • PLC intelligent control cabinet (touch screen)
  • 5-ton hydraulic uncoiler
  • Finished product discharging frame
  • Random tools + wearing parts + instruction manual
