This equipment composed of work frame , upper roll device , main drive device, down roll 

device, side roll device, overturn device ,hydraulic system(parts) , electricity system(parts), 

and  lubricate device.

Work frame:

Body from the base, a fixed side frame and the tip side of the rack, and each part is steel 

welded structure.Were fixed with bolts on both sides of the rack in the base and sides 

of the rack will be used to connect beams connected to rigidity good.Both sides of the rack

 up roller and side rollers with movement of rail, fixed on the side of the rack with roller

bearing for half of the closed frame structure, has overturned overturned side rack 

shelf support devices. Coil force in the process of both sides of the rack by the bear from 

the base not only supports the weight of the machine to ensure the accuracy of the role of 

equipment, but also enables a torque between the drive and chassis balance, and will join

 into one machine. In the now traditional large-scale four-roller bending machine body and

 the main gear is separate from the base installation.

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 HB220-300.

main drive device:

By the Y2 motor, three speed reduction gear, transmission torque to the roller.

 In the high speed shaft of reducer with putting 

the power hydraulic brake.Power supply is 380V/50Hz.

3-4: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  HB220-280.

3-5, Side roller device:

Side of the roller bearing in the radial bearing pedestal, bearing on both sides 

of the rack mounted inside the track, the bottom

 of the piston and oil cylinder connected. Bearing in the liquid under pressure, 

can be tilted up and down along the rail, the size

 of the piston rod of the thrust force according to the needs of steel plate by 

the hydraulic system pressure control valve be adjusted.

The side roll quality alloy steel, heat treatment hardening is  HB220-280.

3-6:Overturn device:

Overturn device through the oil cylinder , hinges torn off and driving overturned on

 a roller bearing aircraft overturned in order to remove products.

3-7:Hydraulic system(parts)

Hydraulic system consists of gear pump, valve, fluid connectors, hydraulic accessories.

Superposition valve series hydraulic valves used, piping layout simple and easy to 

maintain debugging.

System consists of three circuit composed of overpressure protection and pressure

 control loops, synchronization loop, speed loop.

Loop through the main relief valve pressure regulator conditioning system working 

pressure. System working pressure 19.5Mpa.

3-8:Electricity system(parts)

Electrical control system includes the electrical box, operation control panel,  hand-held

 button.Main switch with short circuit protection

 and the main motor overload protection. Reversible motor contactor control by the

 exchange;

 control circuit is controlled by PLC programmable controller system, relay less reliable 

action and long life. Control cabinet with the

 completion of the process of rolling all products control buttons, lights, etc. to the 

operation of the machine control and status control.
