CNC 4 roller plate bending machine, W12 series
Features:
W12 series has the pre-bending function of the plate end and the CNC rolling function. It can feed the metal plate at a time, and can complete the pre-bending and the roll forming of the workpiece without turning the head.
The upper working roll of the machine is the main drive roll, and the lower roll and both sides of the roll are hydraulically driven. The lift displacement is controlled by the computer and is automatically leveled. The screen display shows the synchronization accuracy of ±0.1mm. The tilting and resetting of the rollover bearing body is hydraulic transmission, the balance of the upper roll is equipped with a balance mechanism, which can easily take out the rolled workpiece. It has a mobile stand-alone console that can be moved at any time; the machine is equipped with a safety interlocking device and is safe.

The working roll
Working rolls are made of high-strength high-quality steel 42CrMo material, after forging, roughing, quenching and tempering, HB240 ~ 300, finishing after the intermediate frequency quenching HRC47-58.
Bearing at both ends of the working roll
The four-roll rolling machine adopts very durable double-row self-aligning roller bearings recommended by the industry for each roller.
Optional components
Top support system
The inner rack is the top bracket and is mounted on the rear fuselage.
It consists of a movable stand. The bracket can be translated from the upper part to the lower part according to the size of the barrel, and supports the barrel during the rolling stage. The center stand can be hydraulically and electrically controlled.
Left and right support system
Both sides of the hydraulic support or outside support frame: for large-diameter workpiece on both sides of the holding, to prevent the steel plate rolling process due to weight caused by poor rolling accuracy is not good. The hydraulic support has multiple rows of rolls to better hold the piece. Hydraulic support can be used for raceway when it is flat.
Electric feeding platform: (optional)
It is composed of roll, motor, reducer, hydraulic cylinder, etc. It is used for holding and feeding steel plate to be rolled. Ship and adjust the steel plate to the rolling machine for processing.
Cone bending attachment:(optional)
The cone bending attachment is based on the principle of relative motion. The workpiece and the lower roll or side roll is regarded as stationary, the upper roll is pressed down, and the roll is pressed down and tilted when the cone is reeled.
Hydraulic system
The lower end of the press cylinder is made of non-metal material, which has certain elasticity and large friction coefficient. When cutting the sheet, the press pad can be in close contact with the material plate to provide sufficient friction to effectively prevent the plate from being shaken during the shearing process.
Advantage of our hydraulic system:
- The unique pre-discharge technology is adopted to effectively avoid hydraulic shock and improve the life of the pipeline and seal.
- The hydraulic components are selected YUKEN quality products to ensure the stability of the hydraulic system.
- Each input and output port of the hydraulic system is provided with corresponding detection points, which are convenient for maintenance and fault checking. The oil pump adopts a lower-mounted type and positive pressure oil absorption. At the same time, the filters, level gauges, and all transmitting devices can automatically warn of faults.
- The system is manufactured strictly in accordding to national standards and industry standards. The radius of the tube is reasonable, and the radius is not less than 90°. The transition is smooth and the damper tube clamps are properly arranged, which effectively avoids shock and vibration. Make sure that there is no shock or vibration in the hydraulic circuit.
- The system design fully considers the high efficiency and energy saving, reduces the power waste, and reduces the heat source.
- The hydraulic oil pump and motor set are equipped with a special shock absorbing pad, and the oil suction port is equipped with a shock absorbing throat.
- Provide the test report of the main oil cylinder. System production strictly perform the national standards, and the proper connection point adopts a special sealant. Avoid leakage.
- Provide common fault phenomena and elimination methods for the hydraulic system of rolling machine.
- To ensure the manufacturing quality of the hydraulic system, the system is manufactured according to hydraulic professional manufacturers and the national GB3766-83 “General technical conditions for hydraulic systems.”
Gripping pressure can be set:
For different product rolling process requirements, the clamping force between the upper and lower rolls can be set in advance to effectively prevent excessive pressure on the softer material.
The clamping force is controlled by the hydraulic station relief valve.
CNC control system
Our control system is equipped with an automatic rolling program, which can realize one-button operation. It can automatically roll and roll once at a time. It also has data number, storage and recall functions, and can store hundreds of data. Various specifications of automated rolling. The system is compatible with manual operation programs and can be manually operated when needed.
- The micro-control system includes the main electrical cabinets, control cabinets and other hardware components and special control software.
- Main Specifications:
Display accuracy: ≤±0.05mm
When the lower roll is lifted and the side roll is inclined and lifted and the displacement is synchronously controlled, the synchronization accuracy is: ≤±0.1mm
Sensor displacement resolution: ≤0.05mm
