W11-6*3200 Mechanical 3-roller Plate Rolling Machine Steel Roller Bending
Machine , Sheet Metal Rolling Machine
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 —
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
