W12 Four roller plate bending machine is produced by metallic plate bending and emendation, Which especially suits for metallic plate figuration work, canister, arc, etc. Workpieces can be bent after one feeding, besides, extensive emendation is also available.

• W12 Four roller plate bending machine is widely used in shipbuilding、boiler、aviation、bridge Hydroelectricity, chemical industry、metal structure、and machinery producing industry.
• Compared to three roller plate bending machine, four roller plate bending machine can finish end pre-bending without other device or mold, and the left straight edge is little.
• Compared to asymmetric three roller plate bending machine, Four roller plate bending machine can complete bending without plate turning around.
  
  In this way, the user can improve work efficiency, guarantee the workpiece quality.

Besides, four roller plate bending machine has simple craft work, convenient operation, and reduce the work strength to a large extent.

• The equipment has the pre-bending function of the plate end, which can load the metal plate at one time, and can complete the pre-bending of the plate end and the roll forming of the workpiece without turning the head. The upper working roller of this machine is the main driving roller. The lifting of the lower roller and the rollers on both sides adopts hydraulic transmission. The lifting displacement is controlled by computer, automatic leveling and screen display. The tilting and resetting of the turning bearing body adopts hydraulic transmission. The tail of the upper roller Equipped with a balancing mechanism, it is convenient to unload the rolled workpiece and cylinder. It is equipped with a mobile independent operating table, which can be moved and operated at any time. The machine is equipped with a safety interlock device. The machine has high technical level, complete functions, high precision and convenient operation.
• Features：

1. The machine is a digital display control system, the large-screen display is intuitive and clear, the value is accurate and reliable, the operation is simple, and it is easy to use. The system is equipped with various interlocking interconnection protection measures to effectively prevent misoperation.

2. The operating system is equipped with EPS electronic automatic leveling system, which can automatically adjust the parallelism of the motion axis to ensure product quality.

3. The material alignment, pre-bending, and rounding of this equipment are completed in one rolling process. The remaining straight edge of the pre-bending is less than or equal to 1.5 times the plate thickness, and the rounding accuracy is high, which can meet the requirements of automatic welding.

4. This model adopts inverted side roller cylinder technology, which can effectively reduce the height of the fuselage while improving the sliding stability and reducing equipment failures, which can meet the ground installation requirements to a large extent and reduce the infrastructure construction costs such as user equipment foundation pits.

5. In strict accordance with the process requirements, annealing and shot blasting the welding parts such as the frame to remove the internal pressure and improve the strength and stability of the machine body.

6. The equipment can be equipped with an internal lifting rack and an external bracket, which can effectively control the self-weight deformation of the workpiece during the rolling process, assist the rolling, reduce labor, and improve product quality and work efficiency.

7. The equipment can be equipped with four-roller plate rolling machine’s upper roller taper device technology, which can meet the requirements of users for rolling tapered workpieces, and has the advantages of convenient operation, low use cost, and good rolling quality.
