Three Roll Pinch Pyramid Plate Bending Machine with Cone Bending Facility

- The machine incorporates a fixed top roll & two independently adjustable bottom rolls.
- Both edges of the plate can be pre-bent with a single insertion of the plate.
- Pre-Pinching and Bending are done by clamping the plate between top roll and 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 the top roll and the opposite bottom roll to pre-pinch the other end of the plate. 
- After pre-bending of edges is done, both the bottom rolls are leveled and the plate bending operation is resumed to bend the plate to the desired radius or cylinder.

- The machine frame is all steel welded construction.
- Drive to the machine is a combination of electromechanical 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 tilted and cone can be formed.
- Rolls are made from EN-8 Forged Steel and are ultrasonically tested.
- Machine has a semi-centralized lubrication system.
- Working capacity of the machine is based on plate tensile strength of 45 Kg/mm2.
- Adequate overload protection with relays and limit switches.
- Centralized push button control panel with interlocked circuits.
- Electromagnetic brake system for accurate Edge positioning.
- Roller positioning indicator.
