B. Main Configuration and technical process
The whole line is including 20T hydraulic decoiler, feeding and leveling device, roll forming machine, hydraulic servo punching machine, on line curving machine, corrugated sheet hydraulic cutting machine, output table, hydraulic system and electronic system, etc.
Layout for reference

 
1.20T decoiler
    The decoiler adopt cantilever inter expansion construction, via hydraulic cylinder drive to expanse, hydraulic motor pull the coil rotation, the load capacity is 20T, the coil width is 1200mm, expansion range: ￠500-620mm. The steel coil is craned on the V shape bed, hydraulic oil cylinder drive to move left and right, and let the coil to the decoiler.

   2 Guide and leveling device：
For leveling and pinching to the steel coil, we also match the leveling and feeding device. There are 6 rollers for the guide, 2 rollers for feeding, and 5 rollers for leveling. Roller diameter is ￠140mm, material is 40Cr steel with high frequency quenching treatment.

1. Hydraulic punching device：
2. 。The hydraulic punching device is including rack, base support, punching mould, hydraulic cylinder and press device, 7.5KW servo motor,precision screw, guide rail, etc.
3. Punching cylinder diameter￠120X2 2pcs，core pulling cylinder 30 pcs（The QTY of cylinder is according to the punching hole requirement）.
4. Punching mould material：embossing mode is made by SKD11  die steel ，with forge and grinding. HRC58-62°.
5. corrugated sheet on line curving machine

The on line curving machine is using the reliable arc down style structure, two sets of rollers turn to the centre to make the arc lifting motion, to adjust the arc size according to the product requirement. The device has three sets rollers, there are two sets positioning rollers and press roller, the last one is arc roller, there is a floating roll on the top, and two sets rollers are fixed rollers on the bottom. Which is drived by the reduction gears.

1. Hydraulic cutting blade:

   A.Cutting device: The cutting direction( angle of inclination) can be adjusted according to the radius of curvature of the sheet, which can make the blade movement is close to the arc centre.
