The full hydraulic four roll plate bending machine is a high-efficiency and precision metal rolling and forming equipment widely used for cylindrical and conical workpiece fabrication. Featuring four-roller symmetrical structure and full hydraulic driving system, this machine completes plate feeding, end pre-bending, full-circle rolling and precise rounding in one single clamping process. It completely solves the straight-edge residual problem existing in traditional three-roll rolling machines, requiring no secondary flipping or manual correction. Equipped with synchronized hydraulic control and CNC system, the four-roll plate roller maintains uniform rolling pressure and consistent forming tolerance even during long-term heavy-load operation. It handles carbon steel, stainless steel, alloy steel and other thick metal plates perfectly, delivering smooth, symmetrical and distortion-free cylinder products. Ideal for both small-batch customized production and large-scale standardized industrial manufacturing.
1. Zero Straight Edge Forming Technology
The unique four-roller symmetrical layout realizes one-time clamping and full pre-bending on both plate ends. It completely eliminates residual straight edges, requiring no secondary trimming or re-rolling, greatly improving finished product qualification rate and production efficiency compared with conventional three-roll machines.
2. Full Hydraulic Synchronous Transmission System
All movable rollers are driven by independent hydraulic cylinders with synchronous pressure balance control. The optimized hydraulic circuit provides stable, adjustable rolling force, ensuring uniform metal deformation and consistent roundness tolerance for different plate thicknesses and material hardness.
3. Reinforced Heavy-Duty Mechanical Structure
The integral welded machine frame undergoes high-temperature stress relief treatment to eliminate welding internal stress. High-hardness integral forged rollers feature strong wear resistance and anti-deformation performance, supporting long-term heavy-load rolling without precision attenuation.
4. Intelligent Automatic Operation
Equipped with industrial control system for automatic parameter setting, roller stroke positioning and one-key forming. It can store multiple sets of processing data for batch production, realizing standardized and intelligent rolling operation and reducing manual operation errors.
5. Versatile Multi-Specification Forming Capacity
This hydraulic four-roll roller supports rolling of round cylinders, tapered tubes, arc workpieces and special curved parts. It flexibly processes thin sheets and thick plates of carbon steel, stainless steel, alloy steel and low-temperature steel, meeting diverse industrial forming demands.
6. Low Failure Rate & Easy Maintenance
Adopts integrated hydraulic valve groups and sealed oil circuit design to reduce oil leakage failure. Standardized wearing parts and humanized structural layout simplify daily inspection and maintenance, effectively lowering later-stage operation costs for manufacturing enterprises.
