- Machine construction:

3-1,top roller and driving device
Top roller device is composed of top roller, hydraulic drop end, fixed bearing, hydraulic motor and bearing.
Top roller pass the torque through connecting hydraulic motor and top roller makes
rotation movement. Hydraulic drop end is installed with protection steel bushing.
3-2,lower roller and position inspection device
Lower roller device is composed of lower roller, oil cylinder, bearing of lower roller, self-aligning bearing.
The two side of sliding bearing block (which supports lower roller) coordinate with frame guide rail. Underside is fixed on the two oil cylinder, hydraulic system offer power for up-down movement of lower roller. The rated pressure for main oil cylinder is 16Mpa.The up-down distance is inspected by sensor installed on the lower roller and frame and displayed by LCD.

3-3,side roller device
The side roller device is composed of main oil cylinder of side roller, self-aligning bearing and bearing.
The bearing block support the side roller and the two side of bearing block coordinate with frame guide rail.
Side roller drives side roller bearing block makes up-down movement through four oil cylinders which are installed in the inside of two frames. The up-down distance of two side rollers is inspected by sensor installed on the side roller and frame and displayed by LCD.
3-4,hydraulic drop end
Hydraulic drop end device is composed of oil cylinder, oil cylinder joint, bearing block, oil cylinder bearing and etc.
The hydraulic drop end device is easy to take out the product along Roller shaft.
When the hydraulic drop finishes closing or opening, the stroke of oil cylinder is zero. The power comes from hydraulic station.
3-5,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.

(Plate rolling drawing)
- Hydraulic system
Hydraulic valve adopts Yuken superposition hydraulic valve series, the pipeline lay out is simple, few leakage and easy for maintain.

- Electric control system
- CNC system
Industry control PLC will inspect the lower position and two end of side roller position automatically and control it to ensure synchronization precision ±0.15mm
