HB
Esmech have a wide range of designs for Cut-to-length
lines to suit the exact needs of the customer. With a
reference of about forty-five lines with a width range
of 450mm to 1500mm and thickness range of 0.11mm to 10.0mm
of ferrous and non-ferrous material, HB Esmech has developed
very high expertise. Technical collaboration with PRO-ECO
Ltd. has resulted in the incorporation of the latest technology
in these lines.
Roll Feed Lines :
Normally used for high quality requirements of sheets
for Automotives and white goods, in these lines, the precision
leveller runs continuously at a constant speed and pushes
the material in a loop. A low inertia Feed Roll pulls
the material out of the loop at high speed and stops at
the exact required length, ensuring accurate cut lengths.
Length accuracy of ±0.30mm and diagonal accuracy of ±0.5mm
can be achieved, depending on the selection of electrical
controls. These lines can cut sheets at the rate upto
60 cuts/minute and speeds upto 110mpm.
Start-Stop Lines/Hump Type Lines:
These lines are the ideal choice for customers who
do not require the high production rates associated with
Roll Feed Lines and want to process heavier gauge, non-surface
critical materials.
In these lines, the leveller/flattener works in a start-stop
or run & crawl mode. Strips upto 20mm thick and 2000mm
wide can be processed on such lines.
Flying Die Shear :
These lines are ideal for processing soft or highly
surface critical materials. In these lines, the strip
does not have to stop at any point of time, thus preventing
any marking of the strip.
These lines have shearing dies which accelerate to match
the strip speed and cut at exact length in four-post underdriven
presses.
Rotory Shearing Lines :
These are used for thinner strips at fast speeds.
Typical application is Galvanised and/or colour coated
strips for roofing materials. The precision leveller runs
at a constant speed. The shear blades are mounted on two
eccentrics geared together and activated automatically
to match the sheet speed at the exact length for shearing.
Speeds upto 150mpm can be attained on such lines.

Special Features
 Precision Levellers :
| |
HB Esmech offers 4High, 5High and 6High multi-roll
precision levellers suitable for strip
thicknesses as low as 0.10mm and as high
as 6.0mm. Built to high precision, these
levellers are designed to be adjusted "on the fly" or "as you level". A number
of adjustable back up roll banks ensure
high quality of levelling. Quick change
cassette type models are also available
to increase the range of strip thickness
in the same line. |
Mechanical down-cut shears :
| |
HB Esmech
offers high speed shears with a cut cycle
time as low as 200 milliseconds.
The clearance between blades can be adjusted
very easily and precisely with pre-callibrated
single handwheel setting.
The over-crank design of shears enables
stacking of sheets right under the shear
for damage-free handling of cut-sheets
in the stacker. |
Stacking Systems :
| |
HB Esmech
offer air cushion type or drop type
or combination air-drop type stackers.
End discharge or side discharge systems
coupled with extra features of stack storage,
weighment and conveying can also be provided.
Multiple stackers can be also be provided
to eliminate stack change-over time for
higher productivity. |
Magnetic Stackers :
| |
HB Esmech also manufacture
sophisticated Magnetic Stackers. These
Stackers are essential for stacking
surface critical material on Blanking/Shearing
lines, Trapezoidal shearing lines etc.
Memory functions can be programmed for
hundreds of different sizes & shapes
of blanks for pre-positioning of stack
positions & guides. |
Tail Out Function :
| |
Automatic tail out
function is provided to monitor operations
of the entire line to enable unaided and
damage free cutting upto the last possible
full length sheet after the tail-out of
the coil from the uncoiler. |
