Experience Hassle-free Panel Bending
HIMALAYA Boiler Membrane Panel Bending Machine are capable of forming multi-tube boiler membrane panels.
Himalaya’s machines deliver a multi-fold advantage to your fabrication infrastructure - a remarkably efficient and lasting performance, an unbeatable bending precision, reduced capital expenditure, and lower ongoing operational and maintenance costs.
Panel Bending Machine Design
This machine will have two support rolls and one forming beam. It will be mounted in a rigid Box like frame such that the support rollers can be moved towards each other or away from each other depending on the radius of the bending required.
The movement of the support rollers will be through electromechanical drive. The movement can be operated through push buttons provided on the console.
The pressing beam can be moved back and forth by 2 hydraulic cylinders. The end of stroke accuracy (position and parallelism) will be within ± 1 mm. During approach and return, the parallelism will be in the range of ± 2 mm. The cylinders will be synchronised using PLC.
A push button controlled swing arm is provided at the top to give clearance for removing the panel after bending operation or for changing the rolls.
The required bending angle can be achieved depending upon the pressing roll dia and the position of support rollers. After the required bending angle is achieved, the position of the support rollers can be noted from the mechanical scale provided and the position of pressing rollers can be noted from the digital readout provided on the console. Repetitive jobs can be done faster based on the readings noted for the earlier similar job done.
The control panel and a movable console will be provided for the convenience of the operator.
Our scope does not include movable roller trolleys for supporting the panel. We recommend grooved tooling for thin walled pipes. Cost for one set of dies has been quoted. The tolerance on bend will be generally in the range of ± 0.5 degree or ± 3 mm for radius depending upon the material properties of the pipe (panel).
The HIMALAYA Advantage
What is done to compensate for deflection of rolls during pre-bending and rolling?All rolls are crowned (cambering) for compensating deflection.
What is the arrangement provided for balancing of top roll when swing arm is opened?Top roll is counter balanced automatically once the drop end is opened without any jacks or manual arrangement.
Is there any method to know the position of bottom rolls?DRO (Digital Readout) is housed on the operating console which gives the position of the bottom rolls with respect to the top roll.
What is the capacity for cone bending?Cones can be bent up to the edge-bending capacity of the machine. The bottom rolls can be inclined for the required cone angle.
What is the level of protection for electrical components?Some of the electrical bough outs are IP 55 like motors, switchgears etc. The electrical cabinet will be manufactured as per our standard practices and will meet IP 55 protection.
Is the main drive reversible?Forward and reverse to the main drive is provided. The bottom rolls can be moved up and down individually.
What is the type of oil required?Hydraulic oil – Enklo 68 Planetary Gear box – EP 90
Where are the main machine controls?Operating console houses push buttons for all the operations of the machine. The console is movable so that the operator can keep it at any desired location.
Can we bend hot plates on the machine to get higher thickness capacity?Although the standard machine is not meant for hot rolling, occasional hot rolling can be done (a few jobs per month) provided that suitable precautions are taken.
Some plates have high yield point (YP). The rolling capacities are rated for 26Kg/mm2. How to find the equivalent thickness?Divide the Actual YP by 26. Find square root of this number. Multiply this value by actual plate thickness to get effective thickness.
