Plate rolling machine

3 Roll fixed axis plate bending machine – Model 2520

Available in width of 2000,2500,3100,3600 & 4100 mm.

Capacity in thickness 12, 16, 20, 25 & 30 mm.

Infinitely variable speed of rolling as per requirement.

Faster rolling for smaller thickness.

Main Unique Features of ‘Roll Master’ make plate bending machines

1. Control Panel :

2. Drop end :

3. Cone guide:

4. Section bending:

5. Greater tilting angle:

The control panel is user friendly & most

convenient to operate.

All functions like, bending cyl movement, cone

guide, drop-end, hold & roller rotation start/stop is

on panel. Operator can see bending cylinder

position as digital display on panel.

Most convenient & easy way to

remove rolled shell from machine

due to more clearance between

bottom & top roll & higher degree

of inclination of top roll.

Cone guide which is must for taper/conical

rolling is provided to be operated by push

button & is duly hardened to 55-60 R.C.

hardness with heavy duty bearing within & to

be operated from panel.

An extended shaft provided on both top &

bottom roller to facilitate die mounting

which enables bending of different

sections like, beams, channels, angles,

pipes, flats, round/sq bar bending. Capacity

up to size 200 channel & beam. The operation is by push button on panel.

Greater tilting angle for taper shell

rolling with major dimensional

difference between small & large

diameter.

1. Operation Complete manual

operation

fully automatic by

cyl & button

2. Manpower required Min. 3 to 4 persons Only 1person require.

3. Cone bending manual adjustment By push button adjustment

4. Roundness correction

(Apple effect removal)

Not possible Easily possible by

push button

5. section bending Usually light structural up to

75×75 angle &

100×50 channel

Possible up to size

200 beam & channel

6. Bottom roll support Bush of C. I. or P. B. material Heavy duty bearings

7. Profile More ovality apxly 5mm. Perfect roundness

within 1-2 mm.

8. Operation Time Slow due to

manual work involve

Comparatively fast

since fully automatic

9. Roller position To be decided by scale &

pointer hence not accurate

Digital reading on meter

for ease of parallalism.

10. Bending roller speed Constant Variable (more speed for less

thickness material.)

11. Bearing support Narrow bush hence less

bearing area.

Extra wide bearing housing.

12. Maintenance cost More costly if P.B and G. M.

bush replacement needed.

Bearings less costly than

P.B. Or G.I. bush.

13. Down time Requires 2-3 day to change

bush after existing shaft size

confirmation

Machine can be restarted

within 2-3 hours since

bearing replacement is faster.

14. lubrication To be done manually,

more wastage of oil

Automatic lubrication hence

guaranteed oiling to

bearings.

Standard Features 1. Hardened rolls up to 60 R. C.

2. Cone guide adjustable on button.

3. Section rolling arrangement.

4. digital display for pressure arm A & B

Optional features:

1. Soft rolls.

2. Frame mounted cone guide roller.

3. Fully ground, plated & polished rolls for S.S, copper or C. R. C. Rolling.

4. Inter changeable profile rolls with/without P.U. coating for thin & coated

metal rolling in profile Like G. I./color coated sheets.

5. Material feed table, vertical support for large dia. rolling & shell support.

6. Hardened section bending dies for angle , channel, beam, pipe etc.

7. Moving console for all around operator movement.

8. N.C. / C.N.C. control for mass production.

9. Infinitely Variable roller speed.

10. Automatic central lubrication system.

4 Roll Plate Bending machine

This is a plate bending machine with 4 rollers & can perform Pre

Pinching & bending a plate in single pass.

This machine can roll more tighter diameter compared to 3 Roll plate

bending machine. Usually both top and bottom rollers are driven by G.B.

& motor but in some cases, top roller and 2 side rollers are driven one.

In this type of machine there are no sliding surfaces & the rolls move in

planetary motion for pre pinching of plate. This type of machine has

greater efficiency. Since there is no sliding friction & full power is

utilized for bending which otherwise approximately 30%. Power goes

waste in order to overcome friction loss in case of sliding surface guide

type bending machines.

The minimum diameter that can be rolled is approximately 1.1 times the

top roll diameter.
