Components and Function

Decoiler:
This decoiler is passive type, which could load coil by expanding the bolts fix at coil inner diameter. It’s easy to be operated as an economical solution

Guiding Device:
Adopt guiding bar and sliding block to control the width and position of the steel sheet. The
coil is guided in the correct position and passed to the roll forming system. Can adjust the guiding bar with loosing the fixing bolts to feed sheet in right position. It’s fixed structure
to make sure can not move easily.

Leveling Device:
This device is to make the steel strip go into the roll forming system flatly and straightly. It
consist of seven small leveling rollers (3 pieces up and 4 pieces down), which can
achieve good leveling quality.

Punching Device:
The punching dies adopt Cr12 with quenched treatment. The holes made by these punching
moulds are easy to be installed together. Because the holes are finished with high precision. The device has advanced techniques, quick action, long life and low noise. You could control it easily.

Roll Forming System:
A. Machine frame adopts welding structure with shot blasting and painting treatment

B. All rollers material adopt high quality GCR15 steel with quenching treatment and tempering treatment, and the hardness reaches to HRC58-62. All rollers are treated by full CNC machines to make sure the rollers with good rigidity and precision, and form perfect sheets as per design.
C. All rolling shafts are made by high quality No.45 steel with quenching and tempering treatment, so the shafts with good rigidity which could use for long tern without
deformation.
D. Rolling shaft supporting structure type is steel wall and welded with the basement together to have rigidity.
E. Cycloidal pin gear speed reducer motor driven, the back/forward roller driven by chain, part of upper/lower rollers driven by gear.

Cutting Device:
A. Adopts post cutting, the cutting blade material is Cr12 with quenched treatment.
B. Adopts welded frame for good rigidity.
C. The cutting action is driven by the power from hydraulic station which guarantees the
precision of cutting and low noisy, long life.

Hydraulic Station:
A. Adopts separated hydraulic station for punching device and cutting device.
B. Supply the initial power to the puncher and cuter through a closed oil tank.
C. All valves, motors, pumps and pipes are from high quality Chinese famous brand
suppliers.

PLC Control System:
A. Adopts PLC control and frequency adjust speed, length measurement encoder calculation technology, realize the automatic production.
B. Pressing button Operation, adopt high quality components, such as Mitsubishi PLC,transducer and touching screen, Omron mini-relays, Schneider AC contactor,switches, and so on.
C. The system uses modular structure with convenient, reasonable wiring arrangement.

Finished Panel Supporter:
It can be used to hold finished panels. We supply 2 pieces with length of 2000mm.
Normally 2 pieces supporters together can hold 7000mm panels.
