Pyramid type 3 roll
Plate Bending Machine |
|
| |
|
|
|
|
| |
|
Suitable for
bending M.S. Plates to roll cylinders and making of semicircle
pipes, cones etc. |
|

|
Technical Details: |
|
| |
|
 The machines are
of three roll design, working on pyramid principle. Entire
structure is fabricated with heavy section base, welded
structure. The complete machine is very robust, heavy in
construction to withstand all working conditions. The design is
maintenance free & only part the customer has to take care is
regular lubrication of the bottom & top rolls bushings. The rolls are of carbon forged steel to stand wear
and tear and completely machined. |

machine, no foundation necessary. |
|
| |
|
|
Indicators are
provided at both ends for correct parallel top roll
pressure. |
|
| |
|
|
Horizontal grooves
provided on the bottom rolls for correct
feeding of the plate throughout the length and giving additional
gripping for getting correct shape, pipe etc. for bending light
gauge sheets, top roll positive drive is required. |
|
| |
|
|
Initial pinching
not necessary up to 5 mm. plates. |
|
| |
|
|
Machine runs at a
very slow speed, thus full control on bending curvatures is
attained perfectly. |
|
| |
|
|
Top roll can be
raised/ lowered by two hand operated pressure screws |
|
| |
|
|
Top roll to be
adjusted by hand screw jack for removal of end bracket |
|
| |
|
|
Bottom rolls are
fixed and roll the plate and the top roll
is lowered for pressing the plate to form a cylinder. |
|
| |
|
|
Centre roller
supports below the bottom rolls are provided for
vibration free working |
|
| |
|
|
Top roll can
be tilted for conical bending |
|
| |
|
|
|
| |
|
Drive : |
|
| |
|
All machines are
geared drive. Gears for all plate bending machine are made from
forged steel blanks, by Hobbing process for longevity,, &
durability. In addition fitted with a reduction worm gear box
unit with -oil bath system, totally enclosed for dust free
operation
Hand or electric drive to suit customer demand.
