10mm thickness 6000mm length Mechanical Three Roller Symmetrical Rolling Machine

 Accurl Machine are professional manufacturer of Metal Forming Machine.

 By 2015, we have already been in this field for 17 years.

   Our new factory covers a total area of 46,600 square meters.

   We professional R&D team, and we have World-class design and manufacturing capabilities.

■ 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.■ The machine widely used in petroleum, chemical industry, cement, boiler, shipbuilding, aviation, water conservancy, power transmission towers and other machinery and equipment.

■ 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.

■ adapted for bending metal plate into round, arc, and so on. Its working principle is rotary bending deformation.

■ 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.

■ 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.

■ 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.

■ The machine is widely used in chemical industry, Cement, shipbuilding, boiler, aviation, water control project, Power Transmission Tower, metal structure and the industry of making machinery.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.

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
