W12-8×3000 CNC Hydraulic 4 Rollers Bending Machine Rolling Machine With Separate Controller Price
1. Description:
This machine is four-roller plate rolling machine, top roller is the main drive and do rotation movement, lower roller makes up-down movement to make the plate can get the frication along with length direction, two side rollers makes Up-down movement which is an angel with straight line, which can make the steel plate get the needed plastic deformation. Because adjust the side roller can achieve symmetric bending and asymmetrical bending, the flat end will be very short intheory, comparing with three-roller plate rolling machine, which can save pre-bending procedure and pre-bending device, meanwhile it can make rough leveling of steel plate. It is extensively applied in petroleum industry, chemical industry, boiler, shipbuilding industry, hydroelectricity, metal structure and machinery industry.
2.Machine construction:
A.The main body structure of the machine is composed of upper roller device and driving device, lower roller device, side roller device, hydraulic drop end device, lubrication device, Left and right frame, chassis and etc.
2.1 Top roller and driving device
Top roller device is composed of top roller, hydraulic drop end, fixed bearing,hydraulic motor and bearing.
2.2 Lower roller and position inspection device
Lower roller device is composed of lower roller, oil cylinder, bearing of lower roller, self-aligning bearing.
2.3 Side roller device
The side roller device is composed of main oil cylinder of side roller, self-aligning bearing and bearing.
B. Hydraulic drop end
Hydraulic drop end device is composed of oil cylinder, oil cylinder joint, bearing block, oil cylinder bearing and etc.
C. Balance device
Balance device adopts compact structure, when the tipping rack slip off bearing
face of top roller and make tipping movement, this end of top roller will drop due
to gravity. To make the top roller keep level, the balance device is installed on the
fixed side (out of fixed side frame, namely there is a distance between fixed frame
and balance device) and meanwhile it is fixed on the frame by screws.
D. Hydraulic system.
Consist of gear pump, Solenoid station, and the pipes circuits.
The solenoids made in Tai Wan.
The hydraulic system consists of 3 kinds of circuit, pressure adjusting circuit,
symmetry circuit, speed circuit, etc.
