Metal CNC Plate Rolling Machine Bending Rolls Hydraulic Drive
Features Of Hydraulic Plate Rolling Machine :
The hydraulic rolling machine is widely used in petroleum, chemical industry, cement,
boiler, shipbuilding, aviation, water conservancy, power transmission towers and other
machinery and equipment. Its working principle is rotating bending deformation.
A cylinder can be rolled, including the pre-bending of both ends, feeding the plate
forward through the rolls, one time only. The operator should find only one position for
each side roll, to get the part finished which is supported by permanent lubrication
technology (bearing life period without refueling).
whole structure of the 3 roller rolling machine:
The 3 roller rolling machine is of totally European design: streamlined looking. Frames
of the3 roller rolling machineare fabricated, Roll shafts, materials and bearings used in
production are of European quality. Besides, the torque limit of the machines is very high.
NC playback and CNC graphic control systems are available as optional accessory.
The main structure of thehydraulic plate rolling machineincludes upper roller, lower roller
and horizontal movement mechanism, supporting mechanism, main drive mechanism,
downturn system, left and right machine frame, chassis and balance mechanism, hydraulic
and electrical control systems.
Thehydraulic rolling machineallows for excellent roundness, thanks to the planetary
movement of the side rolls , moving them to the center of the machine (the tightest
geometry available), compared to the inclined linear guides of other brands that,
especially on large diameters, move farther away from the central roll and the plate
clamping. Clamping pressure is adjustable (no-existent skidding, productivity is 80%
than three roller plate rolling machine).
roller bending hydraulic plate rolling machine has a plate end pre-bending function,
which can finish metal sheet feeding one time, and can complete the plate-end
pre-bending and the work piece’s rolling to shape without U-turn. The upper working
roll on the machine is driving roll, the lower roll and two rolls on both sides all apply
hydraulic transmission, the lifting displacement is controlled by computer with
auto-leveling and screen displaying, synchronization accuracy of ± 0.2mm, the pouring
and resetting of the retroflexed bearing body all apply hydraulic transmission, the tail
of the upper roll is equipped with a balancing mechanism which can easily unload the
work piece and cylindrical shell after rolling ,equipped with independent mobile console
which can be moved and operated at any time.
The machine is equipped with safety interlock devices, with high technical merit, full
functions, high precision, easy to operate, which is contemporary ideal CNC plate
In areas of Energy, transportation, petroleum, chemical industry, boiler, shipbuilding
, utilities, metal structures, etc. it is the most ideal choice models to roll round, curve
and tapered work piece.
The machine consists of four working rolls, left and right racks, base, volume cone
device, dumping parts, transmission parts, and assorted sensor, hydraulic system,
electrical system, etc...
