Expressway Guard Rail Roll Forming Machine Highway Guardrail Roll Forming Machine Expressway Guard Rail Roll Forming Machine Application of the Production: Technical Parameters of the Highway Guardrail Roll Forming Machine Highway Guardrail Roll Forming Machine Process 1. Parameter of Machine L Size (L× W× H): 25× 2.1× 1.7 m Gross Weight: 33 Ton 2. Production Flow of Equipment Decoiling_Feeding (take the sheet to the first station)_leveling_Punching of the sheet _ roll forming_hydraulic cut to length_automatic stacker 3. Hydraulic Decoiler: Single unrolling machine, one side can put material L Adopt automatic hydraulic system L Coil weight (Max): 6000 KG L Coil diameter (Max): 1600 mm L Oil cylinder dia: 1200 mm, working pressure: 10Mpa Coil Width (Max. ): 500 mm L Working speed: 0-25 m/min Power: 5.5 KW 4. Feeding and Leveling The leveling roller's mechanical property such as rigidity and roughness concentration of the surface are rising very much after hardening and tempering. It includes pinch roll and leveling roll. The pinch roll can adjust along. The leveling roll uses the whole structure. There are two adjusting point at the front and the end. It can form a certain banked angle to improve the leveling quality. The feeding port of the leveling machine has a pair of guide plain barrelled roll and two pairs of guide vertical roll. The guide vertical roll can moves centered or moves at the same time. It is adjusted by hand wheel, so it is convenient to centered L Feeding the sheet to the guide roller (it is adjustable by right and left). L Feeding roller: Diameter is 160 mm, material is 40CR steel, HRC48-52. L Leveling roller: Upper is 3 rollers, down is 4 stations(total is 7 stations) L Material is 40CR steel, HRC48-52.
