Automatic Double Layer Roll Forming Machine

Same as common single layer roll forming machine, the Automatic Double layer roll forming machine line is also including steel de-coiler, feeding guide and leveling device, manual pre-shear, key roll forming system, hydraulic post cutting, run out table, hydraulic station and PLC(controlling system). The biggest difference is: double layer roll forming machine has two layers, one layer produces one roof design, it is good for saving steel roofing machine layout place.

Whole roll forming machine line is full automatic, producing speed is adjustable and the cutting length, cutting pieces can be set on PLC control system, then roofing machine will process as producing task. Whole forming machine frame, forming rollers and shafts are strictly precision controlled, so if you choose our Automatic Double layer roll forming machine, you will have high production efficiency and easily operation roll forming lines.

Processing Material Specification

1) Effective Width: 1070/1000mm

2) Processing Steel Coil Thickness: 0.4-0.8mm

3) Suitable Raw Materials: pre-painted coil, Galvanized sheet

4) Yield strength of raw material: 345Mpa

Main Components

7 Tons Hydraulic decoiler

There are 2 choices, Mandrel or hydraulic decoiler, the mandrel is shrinking expanding by mechanical device manually, after fix coil to mandrel, then put back the coil with mandrel together to basement.

For current double layer roll forming machine is 7 tons hydraulic de-coiler, there are 4 pcs of claws, powerful open and close. Hydraulic system to expand steel coil inner hole, Coil inner–diameter:480-530mm, with support rack for improving whole structure.

Steel Sheet Feeding Guide Device

It is for ensuring steel sheet feeds smoothly & precisely.

Components: flat steel plate platform, one pair pitching rollers, position stopping block.

The coil is guided in the correct position and passed to the roll forming equipment.

Roll-Forming M/C

Main Frame Structure

The main frame is independently welded for stability and strength.

Exterior wall panels are assembled using screws after surface treatment via rot blasting, ensuring corrosion resistance and durability.

Roller & Shaft Specifications

Roller Material: Made from high-grade No.45 forged steel.

Processing: Rollers are machined using precision CNC equipment and plated with hard chrome coating (0.05mm thickness) to enhance durability and extend service life.

Roller Shaft: Diameter of 75mm; precision machined and polished twice using grinding machines to ensure high dimensional accuracy and a smooth finish on final products.

Drive System

Power transmission by gear/sprocket drive system for reliable and synchronized operation.

Manual clutch provided for switching the drive system between two forming levels (only one level can operate at a time).

Forming Levels & Profiles

Upper Level: Designed for YX25-267.5-1070 profile with 18 forming stations.

Lower Level: Designed for YX45-333.3-1000 profile with 20 forming steps.

Both sets of rollers are CNC machined from 45# steel and coated with hard chrome, good for anti-rust and keeping forming effect no scratches

Motor & Speed Control

Equipped with one 11KW main motor.

Hydraulic Post-Cutting System

This roll forming machine's hydraulic post-cutting system is controlled entirely by the PLC. Once the roll forming process reaches the required sheet length, the control system will automatically pause to perform the cutting action. After cutting is completed, the roll forming line resumes operation without manual intervention, ensuring efficiency and precision.

Cutting Method: Hydraulic driving cut after forming, based on pre-set lengths.

Control System: Fully automatic, with a non-contact photoelectric switch for accurate stroke control.

Structure: hard and strong welded steel frame for long-term durability.

Length Measurement: Automatically measured and controlled by Omron brand encoder.

Hydraulic Station

The hydraulic station uses a gear wheel oil pump to drive the cutter once hydraulic oil is filled into the tank. The system is powered only during cutting, reducing unnecessary energy consumption when idle.

Hydraulic station system included: 1pcs hydraulic tank, 1pcs oil pump, 1pieces of hydraulic pipes, and 2 solenoid valves.

Brand Components: Equipped with top-quality hydraulic system parts to enhance stability and reduce the risk of oil leakage.

Energy Saving: The hydraulic system remains off when not cutting, helping save power and extend component life.

The whole double layer roll forming machine speed can be adjusted due to we have inverter on the control system, and machine line speed is about 20-25m/min.

Profile Stack

 Un-power, total 3 units, with roller on top stack for easy movement
