Specifications
4-roll hydraulic rolling machinehigh efficiency(driving power equivalent 60% traditional)
Permanent lubrication technology
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:
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 produc
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
