Three Roll Fixed Axis:

Information: This Plate Bending Machine is used in combination with press. The material is required to be

feed after pre-pinching in press.

In application with small thickness the material can be pre-bend within the machine,

bring top roll as a press.

This machine can be used to straightening bend plates & for straightening segmental

welded Flange Joints.

The machine is fully hydraulic, there for it can operate on full automatic buttons, And

only a person operate full machine.

Section Bending Attachment:

Extended shafts are given to attach section bending dies. These dies can easily attached &easily

removed from extended shaft.

Some Machine Features: 1. Control panel- All operations like bending, cone guide, drop-end, hold cylinder & roller

rotation is done on the panel. Also digital display gives position of top

roller.

2. Drop End- More clearance between top roller & bottom roller, higher degree of

inclination of top roller make easy material removal.

3. Cone Guide- Hardened cone guide is provided with bearing.

4. Section Bending- Both top & bottom shafts are extended to mount die which enables

different sections like beams, channels, angles, pipes, flats, round/sq bar

bending.

5.Greater tilting angle-Greater tilting angle for taper shell rolling with major dimensional

difference between small & large die.

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.

Optional Features: 1) Heavy Duty Overhead crane can be necessary for bending of thick plates.

2) Lateral Side Supports are also used together with overhead crane to support large

diameter jobs.
