Pre-pinching type, 3 roll
Plate Bending Machine
|
|
| |
|
|
|
|
| |
|
 This machine incorporates a fixed top roll & two independently
adjustable bottom Rolls. Both edges of the Plate can be prebend with
single insertion of the plate. Pre-Pinching & Bending is done by
clamping the M. S. plate between top roll & one
bottom roll and bending the clamped portion by another bottom roll
to the desired radius by Rolling. The same operation is then
repeated using opposite bottom roll & top roll.
 After pre bending of edges is done, both the
bottom rolls are leveled & plant bending operation is resumed to
bend the plate to desired radius or Cylinder.

|
 The machine frame is all
steel welded construction. The machine drive is a combination of
electro mechanical drive with oil cooled gearbox & hydraulic power pack.
For removing the shell; the swing down bracket is hydraulically
operated. For conical bending, bottom rolls can be titled and cone
be formed. Rolls are ultrasonically tested & made from, En-8 forged
steel. The machine has a semi centralized lubrication system. |

Working capacity
of the machine is based on plate tensile strength of 45 Kg/mm2. |
