Why choose hydraulic 4 rolls?
1) Auto-aligning, the plate can be aligned against the side roller
2) The plate is clamped in the tangent position accurately of top
roller and lower roller to get the shortest flat end (excellent
3) One-time rolling. The whole round cylinder can be rolled in one
time, including the pre-bending. Find right position for side
roller, it can be aligned automatically, no need to turn round.
4) Feeding plate. The plate is clamped between top roller and lower
roller in the middle to assure the consistency and ideal location.
5) Accessories. Aligning, pre-bending and rolling are centralized
control. Quick pre-bending and no damage on the plate edge; there
is aligning device on the side supports to remove possible
misalignment in rolling. And the top support is mainly used to roll
big diameter of cylinder, which can replace the over-head crane.
The rolling efficiency can be increased 2 or 3 time higher by using
6) Cone-shape cylinder. The geometric design is good for cone-shape
cylinder rolling, the lower roller can lean to clamp the plate (big
diameter of cone-shape cylinder), which can make the the plate in
this side move quickly. “cone-rolling device” is installed on the
tipping side, and touch with short side (small diameter of
cone-shape diameter), move slowly according to the needed size. The
side roller must lean properly to roll the cone-shape cylinder in
right size. For The standard configuration of Mertal-brand
hydraulic 4 rolls, there are electronic control system for clamping
location of lower roller and slant moving of side roller, which is
much more advanced than competitors’.
7) CNC application. Hydraulic 4 rolls is the most proper machine
model for CNC program plate rolling machine; quick auto-aligning;
reliable “start point” as mechanical point, most proper for CNC
program. Hydraulic clamping roller to clamp the plate tightly all
the time to make sure the stability, precision and location.
One-time rolling: it can be finished by CNC program very simply in
Following users apply to use the machine

improving quality want only one operator, reducing labor costs
due to the large size of the Board, production of high-or for
security reasons require handling device

Double nip roller full drive as standard features -
coiling process in the pre-bending of the sheet securely clamped,
completely avoid slipping phenomenon.
Dual roller drive ensure more stable and reliable gripping, edge of
the sheet can be closer to the nip point.
The sheet edge closer to the nip point, this is the best place to
get the shortest length of the straight edge.
After the completion of the pre-bent, we need to continue to move
the sheet coiled. Full upper and lower rollers driven approach,
from both sides of the sheet holder feeding, feeding clamping force
distribution in the double-sided sheet, ensure a more accurate feed
Further explanation, the upper and lower rollers synchronous
movement, ensures that when rolled sheet and narrow strip when feed
reliable and stable.
- Each independent drive rolls on straight league by hydraulic
Every driver on the roll of straight league by hydraulic motor,
ensures that the plate to the stable and reliable. Direct mode was
the standard characteristics of heavy equipment, torque can be
directly sent to board, avoid the power loss.
High efficiency and energy saving technology --
Low efficiency of the system (speed reducer, copper sleeve, gear
belt, cardan shaft, linear guide) is replaced by a new efficient
method, hydraulic planetary drive coupling on the roller directly,
frictionless swing guide rail, frictionless autocollimation
bearing, multiplex hydraulic power system. The application of
today's most advanced technology greatly reduce the energy loss
(useless) to ensure energy is used for coil plate (useful work).
Completely conform to the international standard for efficient
Other manufacturers on the market of plate bending rolls, drive
roller is only on the roller, the production sheet or narrow board,
under the roller relative to the top roller pressure, usually
produce skid too low, too high usually material deformation, such
as such and such problems. Moreover, they usually device adopts
gear box or the structure of the friction wheel, transmission
efficiency is low, waste energy loss is very big.
