This decoiler with a steel welded structure, decoiling passively, adopts coils with ID of φ500mm. It is operated manually under which it can load coils on both the heads which can be circumgyrated.

2. Flattener

According to the flatness accuracy requirement, the flattener, calculating under the theory of minimum distortion is used to flatten, convey and draught the material. The flattener has 5 flattening rollers, 2 feeding rollers and 2 delivering rollers. And the distance of the rollers can be adjusted according to the thickness and rigidness of the material to ensure an ideal flattening function. The flattening rollers are made of heat treated high alloy steel to ensure the rigidity and abrasion proofed characteristics.

3. Front and Rear Material Stores

In order to match the speed of intermission feeding while punching and the continuous feeding while roll forming for continuous production, in front and rear of the puncher material stores are supplied, in which the length of the material naturally sinks is able to provide a cushion for the interval of punching and the continuing of the roll forming. The dimension of the material stores depends on the forming speed. Photoelectric sensor equipment, mounted in the material stores, can stop or re start the roll former when the accumulated material monitored is too long or less. 

4. Intermission Feeder

This system, adopting sever roller feeder and computer controlling panel on which by input the feeding length the required feeding distance can be reached, is to feed the material into punching area in high accuracy.

5. Mechanical Puncher

The puncher, adopting JF21-63 pressing system, combination pneumatic friction clutch, pressing brake and vertical axes, has an advantage of good rigidity, high accuracy, smooth clutching, flexible moving and low noise.

6. Roll Former

The roll former is designed to have 20 forming stations sitting on steel structured frame. Every station is driven by gear box through universal shaft. The material is rolled through the roll former station by station to form the shape gradually by the rollers of GCr15 bearing steel, which were designed in Germany Roller Designing Software COPRA, processed on CNC lathes and heat treated at HRC56-60 to achieve an accurate profile.
