Product Description

CNC Four-roller plate rolling machine, W12CNC-25*2000 

1. Description:

This machine is four-roller plate rolling machine, top roller is the main drive and do rotation movement, lower roller is drive and 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.
 It is applied in petroleum industry, chemical industry, boiler, shipbuilding industry, hydroelectricity, metal structure and machinery industry.

1. Machine construction:

The main body structure of the machine is composed of upper roller with driving device, lower roller device with driving device, side roller device, hydraulic drop end device, lubrication device, Left and right frame, chassis and etc.

                                                                             (body frame drawing)
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.

1. Hydraulic system

Hydraulic system is composed of gear pump, valve group and assistant pipelines.
Hydraulic valve adopts Yuken superposition hydraulic valve series, the pipeline lay out is simple, few leakage and easy for maintain.

1. Electric control system

The electric control system is made up of electric cabinet, operation control table, portable button box. The power is 380V/50Hz.The main switch has short circuit protection and over-loading protection of main motor. The positive rotation and reverse rotation are controlled by AC contactor; the machine adopts PLC programmable control, which is with few relay, stable and long working life. All the buttons and instruction lights for completing the whole rolling process are on the control table, which can control the whole operation process and working status.

1. CNC system

CNC control system adopts rotation encoder, matching with high reliability industry controller, which builds up a control system of stable performance.
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
