1.The Feature of Mechanical Plate Rolling machine

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

A. 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.

B. 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.

C. 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

A. 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.

B. 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.

C. The Ultra wide roll support with lubrication circuit is mounted within linear slides to prevent
wear and tear.

D. 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.

4.Major parts of the manufacturing process

A. 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
B. Large forgings: cylinder body, gear, gear shaft forging roughcast — surface inspection –
roughing — UT flaw — UT flaw detector heat treatment — finishing semi—finishing — MT
C. 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
