Description of all components  
A)Arm type automatic decoiler 
1. Function and components 
Structure Decoiler type Expanding type Press arm Coil car Hydraulic system Electric control system 
Arm type Passive Hydraulic No No Separated   Shared
2. Parameters 
Max loading capacity            5T    
Suitable coil ID                508mm
Suitable material width(max.)      1250mm
3. Main structure type and features 
1)Machine frame adopts welding structure with shot blasting treatment
2)By using hydraulic cylinder to realize the function of expanding or decrease the inner diameter of decoiler, and finally realizing the function of tightening the coil.
3)Put the steel coil on the middle part of the mandrel, after that let the hydraulic cylinder tighten the coil. While the machine is started, the hydraulic motor will drive the mandrel at first, then the steel sheet will be released, take the sheet to the forming rollers and it will move automatically while the rollers run. After that, the forming rollers will pull the sheet. All the steel coil will tighten the sheet by its braking resistance.
B)Roll forming system 
1. Guide device 
Adopting guiding bar and sliding block to control the width and position of the steel sheet. The sheet is guided in the correct position and runs to the roll forming equipment.
2. Roll forming system 
Roll forming system consist of machine frame, transmission parts and roll forming rollers etc.
1)Machine frame adopts welding structure with shot blasting treatment.

)The roller of this line is made by high quality no.45 steel, all treated by full CNC precision machines, surface is painted with hard chrome, therefore the roller has good rigidity and level velvet, the sheet made by it has good quality and precision profile.   
3)Roller inner supporting structure type: column
4) Cycloidal pin gear speed reducer motor driven, the back/forward roller driven by chain, part of upper/lower rollers driven by gear
5) Adjust the screw bar manually to adjust the distance between upper/lower rollers for difference thickness of sheet.
3. Post-cutting device 
1)Adopts post cutting, the cutting blade material is Cr12 with quenched treatment, after cutting, there is no material wasted.
2)Adopts welded frame for good rigidity.
3) The power of cutting is provided by motor.
C)Finished products support table 
To support the finished panels. The table we supply are 2 pieces with length of 2000mm.
D) Electric control system 
1.Adopts PLC control technology, frequency adjust speed technology, realize the automatic production.
2.System provide good man and machine screen, which can set the bataches, plate length, and quantities.
3.Operation type: Touch screen+ buttton
4.Encoder calculate the number, which has calculation and measure the length function.
5.Adopts MITSUBISH, Frequency.
     E)Hydraulic system 
1.Uncoiler and cutting system adopts separated hydraulic station
2.Main valve adopts Shanghai Lixin brand.
