Double Layer Roll Forming Machine for Glazed Tile And Trapezoidal Roof Panel

Specification of Double Layer Roll Forming Machine

ITEM I: Double Layer Roll Forming Machine for Glazed Tile and Trapezoidal Roof Panel

Engineered to maximize operational floor space and reduce equipment investment, this dual-level manufacturing system produces two distinct metal roofing profiles within a single, compact footprint. By sharing a robust main frame and power system, facilities can optimize their layout without sacrificing output capabilities. The heavy-duty structural design ensures minimal vibration during operation, providing a stable foundation that translates into precise, uniform panels. Operators will notice the smooth, quiet transmission as the steel coils feed through the stations, reflecting the precision engineering of the internal drives. This versatile system is tailored for producing highly durable and weather-resistant metal roofing utilized in industrial facilities, commercial complexes, and modern residential structures. The tactile feel of the finished panels demonstrates the superior forming accuracy achieved by this equipment.

Profile Drawing & Customization Adaptability:

Understanding that architectural requirements vary significantly across different structural projects, our engineering team supports deep customization based on the exclusive profile drawings provided by clients. This ensures perfect adaptation for producing complex glazed tiles and trapezoidal roof panels. The visual diagrams below illustrate the precise geometric configurations that this machine is capable of replicating with outstanding fidelity.

Material Specifications:

Achieving structural integrity in the final roofing panels begins with precise material handling. The feeding mechanism handles specific gauges smoothly, preventing surface scratching or coating damage to the pre-painted coils. The resulting panels exhibit excellent weather resistance and load-bearing capacity. Precision is paramount, and strict dimensional control is maintained throughout the continuous forming process to ensure that every panel aligns perfectly during final structural installation.

Machine Components

Every module within this dual-level system is constructed following strict international manufacturing standards. The integration of high-strength welding with precision machining ensures that the equipment withstands continuous, heavy-duty production cycles while maintaining exacting tolerances. The following breakdown details the core components that drive the machine's exceptional performance and longevity.

1) Manual Decoiler: 2sets

The production line begins with the material feeding stage, utilizing reliable uncoiling mechanisms. These robust units provide a stable unwinding process for heavy steel coils, preventing material slack or tangling before it enters the main forming section. The mechanical tensioning ensures a consistent feed rate, which is critical for maintaining the tight tolerances downstream.

2) Cold Rolling Mill:

Constructed to endure decades of heavy industrial use, the main body frame provides exceptional rigidity against lateral forces. To minimize waste, it comes equipped with a manual precutter for easy operation and save material. The core forming rollers undergo rigorous processing and heat treatment, leaving a surface that feels exceptionally smooth to the touch and protects the pre-painted coil finishes. This smart control mechanism allows operators to switch between the upper and lower profiles swiftly without tedious manual recalibration.

• With feeding material guide, body frame made from H450 type steel by welding;
• With manual precutter for easy operation and save material:
• Sideboard thickness: 18mm
• Rollers manufactured from 45# steel, CNC lathes, Heat Treatment, hard Chrome Coated with thickness 0.04mm, surface with mirror treatment
• Shafts Diameter=ф90mm/ ф75mm, precision machined;
• Motor driving, Gear/Sprocket transmission, about 14/18 steps to form;
• Main Motor=7.5KW, Frequency speed control, Forming speed approx.15m/min
• Two layers can’t work at the same time
• Both roll forming groups shared a machine base, motor and control cabinet, and through clutch switch to achieve a dual purpose.
• All the screw bolts with grade 8.8 to ensure fix the machine structure tightly and long life during the machine long time running.
• Real forming speed : 15-20m/min (Not include cutting time)

3) Hydraulic Post Cutting device:

Delivering a clean, distortion-free edge on every panel, the cutting mechanism operates with immense precision. The sheer force is generated by a dedicated hydraulic station, ensuring synchronized performance with the main drive. The cutting tool material is forged from premium alloys, undergoing precise thermal processing for unmatched hardness and wear resistance. To maintain optimal fluid health, the system is equipped with advanced filtration, ensuring smooth and quiet operation during millions of cutting cycles.

• Post cut, stop to cutting, two pieces cutting blades, no blanking
• Hydraulic motor: 4kw, Hydraulic pressure range: 0-8Mpa
• Cutting tool material: Cr12MoV ( = SKD11 with at least one million times of cutting life ), Heat treatment to HRC58-62 degree
• The cutting power is provided by the main engine hydraulic station
• The hydraulic system with oil filter for the oil filtration, to ensure the circulated oil is clean and lengthen the life of hydraulic system (See the picture below)
• Hydraulic oil number: Shell Tellus S2 M 46 or equal model

4) PLC Control System

The neurological center of this equipment is its advanced digital interface. Designed to minimize human error, the system allows operators to easily program batch quantities and lengths. The rapid processing capability of the integrated electronics ensures that every cut is executed with pinpoint accuracy. This smart control hub significantly streamlines the transition when utilizing the mechanical clutch to switch between the upper and lower forming tiers.

• Control the quantity and cutting length automatically
• Combined with: PLC, Inverter, Touch Screen, Encoder, etc
• Cut-to-Length Tolerance ≤±1 mm
• Control Voltage 24V

5) Exit rack:

Once the finished panels are sheared to the exact programmed length, they transition smoothly onto the receiving tables. This friction-reducing design protects the pristine surface of the newly formed glazed tiles or trapezoidal sheets as they are manually offloaded and stacked for packaging, ensuring the final product reaches the end-user in flawless condition.

• Un-powered, 2 units, with rollers on it for easy movement
