W12-20*2500 CNC Hydraulic Four-Roller Plate Rolling Machine Round, Curved, Tapered Workpieces Forming
Description:
W12CNC series four-roller plate rolling machine is a four-roller CNC plate rolling machine that introduces advanced technology from Germany, is controlled by PLC programmable digital, fully hydraulically driven, and realizes automatic rolling.
Advantages:
It has advanced structure, superior performance, good precision, high efficiency, convenient operation, and is the leading technology among similar products in the world.
The position of the upper roller is fixed when rolling the plate, the lower roller moves upward in a straight line to clamp the steel plate, and the two side rollers move upward by the linear guide to adjust the radius of curvature of the reel, and the metal sheet can be loaded at one time without turning around.
The automatic mode is used in batch rolling, and the consistency of the same batch of workpieces is good.
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.
