STRAIGHTENING MACHINE
THE MACHINE:
Machine provide a range of out standing thick plates and precision of
Dead Flat Sheets in Steel and Non-Ferrous Metals. They operate on the
Principal employing 5 to 25 ROLLS relatively.
Big and small diameter backed up to 1,2,3 and 5 rows of support rolls,
which prevent the work rolls from deflecting under the loading.
THE MAIN WORKING ROLLS:
Rolls are of Carbon Chrome Alloy Steel Hardened to 85-90.Scleroscope
on the Barrel, Mounted in Slide stock bearings of Phosphorous Bronze/
Roller/Spherical/Needle bearings entirely surrounding the roll journal.
All the rolls are individually driven by couplings/wobblers & wobblers
Shafts / Universal couplings of special design, from totally enclosed
pinion box.
* THE SUPPORT ROLLS are arranged in Rows or banks, of 2,3,4,5
rows along the length of the working rolls at all times.
* The Roll Driving Pinions are machined from solid Nickel Chrome Steel
Forgings with single helical machine cut teeth gears and carried on
Phosphorous Bronze block bearings mounted in the main pinion box.
* THE ROLL HOUSINGS are steel and rest on the steel bed plate of
ample strength and rigidity. Bed plate forms for the driving motor and
worm reduction unit, the output shaft of shear pin coupled to the
gear box.
* OPPERATIONAL ADJUSTMENTS are provided to all sizes
of Machines.
* THE TOP WORKING ROLLS and support rolls bodily adjustable
vertically by the large central hand wheel, through machine. Gearing
twin screws in each housing. The screws work in nuts and the top gear
is totally enclosed in the casing which bearing blocks are lifting rods
taking the weight of the main bearing Block.
* THE TOP ROLLS Block has half round rumious at each end, The
sheet main & support Rolls, are adjustable in a radial path by means
of the hand lever which works around with this adjustment in operation
and until it finally emerges in a dead flat sheet.
* THE UPPER ROLL neck bearings at each end can be adjusted
Individually to permit the upper rolls to being accurately lined up with
the lower set.
* THE MACHINE is provided with special adjustment for flexing work rolls
and will remove the buckles and produce good flat sheet.
* LUBRICATION is by dip and flash in the driving gear box. The roll driving
pinions and the couplings are totally enclosed and sprayed with oil from a
external pump.
* THE MAIN WORKING ROLLS and the support roll bearing are arranged
for greasing & oiling by grease gun in a each bearing block.
* THE OPERATING SPEED of the machines can be any normal condition,
constant or variable speed driving motors can be fitted.
