Advanced Servo Drive Arc Shearing Machine
High Precision Dynamic Rotary Flying Shear for Efficient Metal Sheet Production
Dongguang Hengfu Roll Forming Machine Co., Ltd. introduces a professional precision servo-controlled cold hard plate circular bending machine, a high-efficiency metal forming solution built for industrial-grade production. This machine integrates advanced servo drive technology, robust mechanical design, and intelligent control systems to deliver consistent, high-accuracy circular forming for cold hard plates and other metal materials.
With reliable performance, long service life, and strict quality assurance, it has become a preferred choice for metal processing, tank fabrication, and structural manufacturing enterprises worldwide.
Advanced Servo Control System
The machine is powered by a high-precision servo control system that enables fully automatic, programmable circular bending operations. This advanced drive system provides precise speed and position regulation, ensuring uniform curvature, even stress distribution, and zero material deformation during cold forming.
Compared with traditional mechanical bending equipment, the servo-controlled design significantly improves forming accuracy, reduces scrap rates, and supports flexible production for customized circular workpieces with varying diameters and thicknesses, meeting diverse production needs.
Robust Construction & Durability
Constructed with a heavy-duty reinforced steel frame and high-rigidity mechanical structure, this circular bending machine is engineered to withstand high forming forces during continuous operation without structural deformation. It is specially optimized for processing cold hard plates, carbon steel, and other common metal materials.
The precision-machined rollers and transmission components ensure smooth, low-vibration operation, extending the equipment's service life and minimizing maintenance costs.
Automated Operation & Safety Features
The machine features a fully automated production workflow from plate feeding to final forming, paired with an intuitive PLC touchscreen control interface for simple operation and quick parameter adjustment. Operators can easily set bending radius, plate thickness, and production speed, reducing training time and human error.
Multiple safety protection functions, including overload protection and emergency stop, are integrated to ensure safe operation in high-intensity production environments, fully protecting operators and equipment.
