Trapezoidal Roof Panel Roll Forming Line Working Process
Decoiling → feeding → roll forming → cutting → conveying final products to the runout table

Machine Components
(1) Hydralic decoiler - 1 set (5 tons)
(2) Main roll former - 1 set (guiding device included)
(3) Hydraulic cutter - 1 set
(4) Hydraulic station - 1set
(5) PLC control system - 1 set
(6) Runout table - 1set (total length is 4 meters)

Component Details
1. Hydraulic decoiler
1) Machine frame: welding structure with shot blasting treatment.
2) Description: Put the steel coil on the middle part of the mandrel, then tighten the coil through the hydraulic cylinder. After starting the machine, driven by the hydraulic motor, the steel sheet will be released. Take the sheet to the forming rollers and it will move automatically while the rollers run.
3) The light control is used to adjust the releasing speed.
4) Max. loading capacity of decoiler: 5000kg.


2. Guiding device
1) It adopts guiding bar and sliding block to control the width and position of the steel sheet.
2) The sheet is guided in the correct position and moves to the roll forming equipment.


3. Main roll former
1) Machine frame: welding structure with blasting treatment.
2) The roller is made of high quality No. 45 steel with hard chrome plated surface.
3) Inner support structure of roller: guiding column.
4) Back/forward movement of roller is driven by chain, and part of the upward/downward movement is driven by gear.
5) Main motor power: 6kW (according to actual design).
6) Manually adjust the screw bar to adjust the distance between upper and lower rollers for sheets with different thicknesses.


4. Hydraulic cutting device
1) Cutting blade material: Cr12, quenching treated.
2) Welded frame for enhanced rigidity.
3) The power of cutting is supplied by motor.


5. Runout table
1) For supporting the finished panels.
2) The runout table is designed with two parts, with its length of 4 meters.
3) This table can be disassembled easily to satisfy requirements of different working conditions.


6. Hydraulic station
1) The hydraulic station supplies power for the hydraulic decoiler, decoiler car and cutting device.
2) All hydraulic accessories are purchased from well-known Chinese brands.

7. PLC control system
1) Mitsubishi PLC control and frequency speed adjustment help realize automatic production.
2) Human and machine interface facilitates the setting of plate length, quantity, etc.
3) Operation: touch screen and buttons.
