First:FEATURE OF Mechanical Plate Rolling machine W11 1. The machine adopts 3-roller asymmetrical structure with the upper roller as the main drive and the lower roller making vertical movement so as to clamp the plate materials tight. The machine drive comes from the engagement between the gear of the lower roller and the gear of the upper roller. 2. The machine is the most precise 3-roll machine in its category. The RGS design reduces to a minimum the distance between the bending points guaranteeing higher bending accuracy. 3. The Ultra wide roll support with lubrication circuit is mounted within linear slides to prevent wear and tear. 4. The very high rotation power is a guarantee of the Machine superior rolling torque and speed, available without loss of energy as all three rolls are driven independently by Gear and gearboxes directly coupled to the rolls shafts. Second:Major parts of the manufacturing process 1. Working rollers: cast steel ingot (chemical composition analysis): check performance-forging roughcast — forging annealing-UT flaw — roughing (mechanical tests)-heat treatment (hardening and tempering) — UT flaw — semi finishing — finishing — MT 2. Large forgings: cylinder body, gear, gear shaft forging roughcast — surface inspection – roughing — UT flaw — UT flaw detector heat treatment — finishing semi—finishing — MT 3. Welding structure: racks, chassis, wheel box Plate into the factory (chemical composition analysis, mechanical properties test) — pretreatment — for sheet metal cutting-welding-seam UT or RT flaw — annealing treatment — roughing-finishing— vibration destressing—hot blasting —finishing 5-4 Major parts of the manufacturing process. Third: Machine Application & Usage -Boiler Tank , Air Conditioning Channels, Sheet Metal Cover. -Cone Making & other Aluminum & Steel Fabrication, Marine & Ship Building, Pressure Vassals, Wind Mills. Fourth: Bending Process : -Place the Plate between bottom and top rolls by adjusting top roll manually. -Down the top roll and give pressure on the plate. Then start Main motor in clock wise direction till one end of the plate comes over first bottom roll reverse the motors and get second end on second bottom. -Continue above process until you et desired as shown in picture.
