4 Roll Plate Rolls Heavy Duty CNC Hydraulic Sheet Metal Pipe Tube
Roller Bender Rolling Bending Forming Pressing Folding Machine
Equipment Product DescriptionThis four roll plate bending
rolls are recognized worldwide as the fastest, safest, most precise
and easy to use plate roll available in the all range. This is a
fully hydraulic 4-roll bending machine with pre-bending. Rolls
length up to 6.000mm, plate thickness up to 150 mm This
Advanced Design Has The Following Benefits Such As: (1) Plate
is introduced horizontally (and not tilted as on the three roll
double pinch)(2) Plate is squared instantly against the back roll
(reducing risk of a mis-matched end condition of the part)(3)
Requires space only on one side of the machine, where the plate is
introduced to the machine(4) Greatly reduced flat-end (due to
better pre-bending) thanks to the clamping roll that can take the
edge to the precise tangent points of the top and bottom rolls(5)
It is the fastest machine to roll a can, as it would require only
one position for each side bending roll(6) The entire cylinder can
be finished in only one pass (within a suitable capacity),
including pre-bending of the edges* No need to pre-bend both ends
before starting to roll the entire cylinder, as required with a 3
roll* No need to remove, turn and re-insert the plate as on a 3
roll single pinch(7) The four roll could be even 50-80% faster and
more productive than any style three roll(8) The most suitable for
CNC operation, as the plate is under a better control, clamped
between the top and bottom rolls, until the part is
finished The Four Roll Design Is Recommend For
Clients Who: 1. Wish to operate through CNC, with less
dependence on operator skills2. Look for more steady quality of the
rolled products. 3. Look for high productivity, and increased
profits. 4. Require good accuracy and quality
improvements. 5. Need handling equipment for larger plates,
who are also concerned for production or safety reasons.6. Are new
to plate rolling, as it is the easiest plate roll to
operate. Product

Advantages Main Features1. Extremely robust structure
machined with CNC control machines2. Two hydraulic motors coupled
to planetary gear units for the rotation of the two central rolls3.
Hardened rolls / Hardened and polished rolls4. Separate control
desk on wheels5. Hydraulic opening of shoulder by control desk6.
Hydraulic inclination of lateral rolls for conical bending directly
from control desk7. Numerical control for automatic production8.
Movements of rolls on swing guides to reduce flat part9. It can be
used to roll tubes, tube segments, rounded boxes, ovals or other
shapes.10. Rolls rotation on high resistance selfaligning
bearings11. Rolls Cambering: know how variable cambering to avoid
reel and barrel effect to increase bending performance and
precision FAQ(1) How long is the service life of your
product?It depend on the worker skills and experience and working
hours every day, if do normal maintenence for the rolling machine
under instruction, its life can upto 10 years. and we need to see
the working plan every day, if working 12 hours even more, that
will effect the service life. (2) What are the
specific categories of your products?We have main 3 kinds of roll
bending machine, Mechanical 3 roller, hydraulic 3 roller with
prebending and hydraulic 4 roller with pre
bending. (3) What are the specifications and styles
of existing products?We have light and heavy types rolling machine,
thickness from 6-150mm, width 1000-12000mm, and we can make special
machine as per customer special request, for example, smaller
rolling diameter, special application like oil pipe, wind tower,
loader etc. Rolling Process /* January 22,
