Structure brief introduction
Its basic structure is two bottom rollers are fixed and symmetrically arranged corresponding to the top roller.
Both of the bottom rollers are drive rollers, which rotates by motor, gear box and distributor case.
The top roller is passive roller whose lifting is hydraulic transmission and the lifting displacement is calculated and controlled by computer, which can self levels and displays on screen, and the synchronisms is ±0.2mm.
The tilting and reset of tilting part is driven by hydraulic cylinder and there is balance mechanism at the end of top roller. When the tilting part discharges the work piece, the top roller is in the state of balance because of the balance mechanism, which is convenient for discharging.
|The Feature of Mechanical Plate Rolling machine :|
1. The machine widely used in petroleum, chemical industry, cement, boiler, shipbuilding, aviation, water conservancy, power transmission towers and other machinery and equipment. Its working principle is rotating bending deformation. For the upper roller can be moved no matter up and down, but also horizontally, so no need additional press or equipment, can realize bending, as well as correction of the workpiece.
|2.The whole structure of Mechanical Plate Rolling machine :|
1. The machine adopts 3-roller symmetrical structure with the upper roller moving vertically in the center between the two lower rollers, which is achieved through the drive of the screw, the unt, the worm and the lead screw.
2. The two lower rollers rotates, and provides the plate materials with torque through the engagement of the output gear of the moderator with the gear of the lower rollers.
3. adapted for bending metal plate into round, arc, and so on. Its working principle is rotary bending deformation. This product is widely used in chemical industry, Cement, shipbuilding, boiler, aviation, water control project, Power Transmission Tower, metal structure and the industry of making machinery.
|3.The Feature of Mechanical Plate Rolling machine :|
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.
|3.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
