  1.       Machine components and structure introduction   5.1,Decoiler   Ø   Driven by electrical motor Ø   Hydraulic expanding with a connecting rod mechanism   Ø   Mounted with pneumatic braking device Ø   Mounted with eight coil material link stopper. When loading the coil, fix two material link stopper at each side of coil sheet to prevent it from loosening.         5.2,Leveler   Ø   It consists of 7 leveling rollers, two pinch rollers and five leveling rollers. Ø   Adopt motor driving. Ø   The leveling rollers can be adjusted to be up and down through one    screw rod and pinch rollers through one pneumatic cylinder       5.3,lubricating device   Ø   This an independent device which is installed before entrance of roll forming to prevent zinc coating from scratch.       5.4,Roll forming unit   Ø   Adopt independent column wall structure and independent gear box transmission design. Ø   Adopt quick cassette shifting design when to change profiles, this design can’t be mounted with safety guard due to the cassette replacement. Ø   Roll forming stations: 18+18 stands(depend on final design, leave space on the machine base for extra four stands of rollers) Ø   Shaft diameter: Ø60mm(depend on final design) Ø   The lower rollers are fixed while the upper ones can be adjusted through screw rod to adjust the gap between upper and lower rollers. Ø   Side nuts of roll forming stands wall rotate with counterclockwise (lower shaft)and clockwise (upper shaft); Ø   Roll forming stands wall material: QT470. Ø   Main shaft material: 40Cr ,hardness is HRC45 after quenching treatment Ø   Roll forming unit motor power: about 15KW   Rollers:   Ø   Rollers material: Cr12 hardness is HRC 58-62 with quenching treatment and polishing treatment Ø   All rollers is marked at the side and the spacers is marked on the surface for future replacement.
