W12-30X2500mm 4 rolls small sheet roller bending machine for metal
1.Totally European design,streamlined looking,frames of our
machines are fabricated, welded steel (ST-52). Roll shafts,
materials and bearings used in production are European quality.
Also the torque limit of the machines is very high.
NC playback and CNC graphic control systems are available as
2.The main structure of the equipment includes upper roller, lower
roller and horizontal movement mechanism, supporting mechanism, 4
roller rolling machine main drive mechanism,downturn system, left
and right machine frame, chassis and balance mechanism, hydraulic
and electrical control systems.
3.The model MH has both the upper and the lower roll powered with
hydraulic motor and planetary gear box.
4. Emergency system: Safety string barier around the machine and
emergency push button.
5. Machine is equipped with two speed working system which is
controlled from Mobile Control Panel.
The Feature of Hydraulic Plate Rolling machine
1. The machine 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.
2. 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 one only position for each side roll, to
get part finished. Permanent lubrication technology(bearing life
period without refueling).
Hydraulic system provides power to lift bottom and side rollers
through driving cylinders, also controls tilting cylinder up and
down. The hydraulic system works reliable with reasonable design.
In order to guarantee oil clean, system is equipped with oil
sucking & returning filters with high accuracy. The radial
quick joints particularly used in metallurgical & mining are
applied in the hydraulic pipes and valves to avoid leaking.
The main valves of the hydraulic system are the products of the
Taiwan Northman Co., Ltd. or abroad. Pump oil filters, motors and
seals are products of famous producers inland. All of them are
advanced performances and reliable quality. All hydraulic parts
have passed strict inspection and test to eliminate hidden trouble
Application of 3-roller and 4-roller plate bending machine,plate
rolling machine,plate roller
3 Rollers and 4 rollers rolling machine,as the shaping equipment
for bending,rolling,leveling of metal plate,are widely used in the
industries of shipbuilding ,boiler,airspace,water and electricity
,decoration and metal structure,and the features complete
specifications,multiple types,well-designed structure,and and
advanced techniques to meet customer’ requirements.
Upper roll device
The up roller gear drive from the main for turning, the ends of the
SP-1 bearing support, drive-side through the flat key, off the main
drive gear and connect the device to transfer torque, tip-side with
the protection of Steel .
The material of the up roller is 42CrMo, heat hardening is
Down roller device:
Down roller supports under the bearing, the bearing housings on
both sides of the rack mounted inside the track, the bottom of the
piston and cylinder connected. Bearing in the liquid under pressure
can rise and fall along the rail, according to the size of the
thrust rod, steel plate under the roller clamping force required by
the hydraulic system pressure control valve be adjusted.Addition of
the down lower rollers can roll adjustment, improve the accuracy of
product under the same material heat treatment hardening is
2. Online video authentication machine work.
3. Cutting samples provided by DHL.
1. Supplier will provide detail manual for software, hardware
and trouble shooting, also supplier should give necessary
guidance online if Buyer need. If it’s necessary, Buyer
should send regular his technical staff to Supplier for
