Packaging list of main components

Technical parameters of main components:

5T hydraulic decoiler

1. Supporting the coils and doing uncoiling. The capacity is 5 Tons(max).
2. It adopts the hydraulic oil cylinder to make the decoiler expandable and fit to the inner diameter of coils.
3. Motor drive the coils running and can do forward and reverse running as well as do the decoiling with tension.
4. The core can ensure the expand range φ450 of the coils inner diameter. It will provide the rubber band to ensure the 550 mm diameter.
5. Carrying capacity: 5 tons
6. Max coil width: 500 mm
7. Feeding speed: 0-20 m/min (adjustable)
8. Driving motor power: 3 kw
9. Hydraulic motor power: 3 kw
10. Structure: welding by the steel plates and profiled bar.
11. The decoiler is equipped with the brake system
12. With pressure arm, can prevent the material from falling

Feeding and leveling device and punching

1. Usage: Make sure inputted steel sheet straight and neat and then roll forming process could be made accurate.
2. 7 rollers leveling:top three,down four +two lead.
3. Roller material:Cr15
4. Roller diameter:75mm
5. The material of rollers could stop scratching the zinc of the steel.
6. Structure: The frame adopts a gantry type and is made into a whole. The two sets of punching machines are two punching machines, and the power source is the cylinder pressure type: the hole position is fixed in the longitudinal direction,
7. The main parameters:

• Punching type: Hydraulic stop punching
• Punching unit quantity: 2 sets with cylinder driving
• Mold material : Cr12
• Maximum punching plate thickness:4mm
