5.6 HIGHT PRECISION STRIP LEVELING MACHINE WITH 2 PINCH ROLLS Number of rollers: 19 Diameter of rollers: 60mm (strip thickness 0.5 3.0mm) Passing width: 1600mm Material thickness range: 0.5mm 3.0mm Setting of roller frame: motorized, automatic adjustment Opening stroke: 150mm Measuring device: Digital Readout: Metric Supporting of rollers: Needle bearings Sealing of bearings: Rotary shaft seals Harness of rollers: HRC60 Drive of rollers: Individual drive Gearing: Distribution gearing Lubrication Automatic oil circulation system Drive: AC motor Speed: 0 60m/min Feeding speed: 0-10m/min Flatness: 1.5mm/m2 Number of pinch rollers: 2 Diameter of pinch rolls: 250mm Feeding of pinch rollers: Hydraulically Drive of pinch rollers: Both rollers by leveler gearing Surface of pinch rollers: Harden chrome coated MOTORIZED AUTOMATIC ADJUSTMENT The setting of the machine for the material thickness to be leveled is done automatically with a motor driven device by means of the data storage. The setting accuracy for inlet and outlet is 0.01mm being shown at the visualization. The four points of leveling distance can be automatic adjusted separately. (Left & right points is controlled by hydraulic cylinder and backward & forward points is controlled by motors) LEVELING ROLLERS: The machine is equipped with 19 leveling rollers with roller diameter of 60mm each. These leveling rollers are made of case harden stell with a solidity of 900 1300M/mm2 according to the diameter. The rollers have a hardness of HRC60 and are smoothly polished. INTERMEDIATE ROLLERS To avoid any marks on the material, which could be caused by the supporting rollers. The leveling machine is fitted with 19 intermediate rollers. They are spirally grooved and serve simultaneously as cleaning rollers. BACKUP ROLLERS For avoiding any bending the leveling rollers are supported. The support is carried out with big-dimensioned supporting rollers, which is run by bearings and are maintenance free. DRIVE OF LEVELING ROLLERS Each leveling roller is driven individually by the distributor gear via a universal shaft. LEVELING ROLLER BEARINGS The leveling rollers are mounted in needle-bearings. The bearings being sealed by means of simmer rings. The bearing points are supplied with oil by the automatic circulation oiling system. LUBRICATION The universal shafts are connected to the automatic oil circulation system. GEARING The gearbox is reduced. The hardened and ground toothed wheels are rotating in an oil bath
