Sheet Mechanical Plate Rolling Machine / 3 Roll Bending Machine For Sale

Machine Structure:

The machine is composed by three symmetrical roller, the upper roller is in the central

vertical position above two bottom rollers for vertical up and down movement, the bottom

rollers get the conversion motion by the screw rod and screw nut worm drive. The up roller

is engaged with the bottom gear by the output gear of the reducer. The machine is in a full

total structure, The working part, the main transmission part are equipped in one bottom

rigid welded base, be convenient for installation and commissioning.

Description:

Mechanical Symmetrical 3 Roller Plate Bending Machine
The whole structure of Mechanical Plate Rolling machine:
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 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. 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.

2. The Feature of Mechanical Plate Rolling machine:
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 Ultra wide roll support with lubrication circuit is mounted within linear slides to prevent wear

and tear.
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 gear

boxes directly coupled to the rolls shafts.

3. Major parts of the manufacturing process:
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
Large forgings: Cylinder body, gear, gear shaft forging roughcast — Surface inspection

roughing — UT flaw — UT flaw detector heat treatment — Finishing semi— Finishing — MT
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
4. Major parts of the manufacturing process.

Character:

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 nut, the worm and he lead screw, The two lower rollers rotates, and provides the plate

materials with torque through the engagement of the output gear of the moderator with the

moderator with the gear of the lower rollers. The disadvantage of the machine is that the ends

of the plate materials need to have the help from other equipment for pre-bending.
