Product Features:

1. The machine is equipped with a high-performance CNC control platform, integrated with a PLC controller and an intuitive touchscreen Human–Machine Interface (HMI). This intelligent control architecture enables convenient program input, real-time process supervision, and efficient production management, ensuring stable equipment operation and simplified daily operation.

2. The equipment adopts ultrasonic-frequency induction heating technology, delivering rapid, energy-efficient, and environmentally friendly heating performance. This advanced heating solution increases production productivity, lowers energy consumption and operating costs, and fully complies with modern environmental protection and sustainable manufacturing standards.

3. Designed as a comprehensive forming system, the machine eliminates the requirement for auxiliary tooling or frequent die replacement. The integrated design minimizes setup time, simplifies production procedures, and significantly improves manufacturing efficiency.

4. Utilizing advanced CNC positioning and motion control technology, the machine achieves highly accurate and repeatable bending results. This ensures consistent product quality, excellent dimensional accuracy, enhanced production capacity, and reliable long-term process stability.

5. The equipment incorporates a self-contained hydraulic power unit integrated with a complete electrical control system. This configuration provides dependable operation, convenient maintenance, enhanced operational safety, and excellent suitability for continuous heavy-duty industrial production.

6. The cold-forming function is suitable for processing angle steel sections up to L100 × L100 × 10 mm, provided the bending angle does not exceed 5°. This capability ensures controlled deformation, excellent dimensional consistency, and high forming accuracy while minimizing material stress.

7. Under standard production conditions, a typical cold bending cycle requires approximately 10 seconds per workpiece, while a thermal bending cycle averages approximately 120 seconds, depending on material specifications and workpiece dimensions. Thermal bending commences after the material reaches approximately 800°C (red-hot condition), with heating parameters automatically optimized according to material characteristics and required bending specifications.

8. Once machining parameters have been entered, the automatic operating sequence can be initiated using either the start button or a foot switch. The system automatically completes the entire forming process, including workpiece positioning, induction heating, automatic retraction of the heating unit, hydraulic bending, ram return, and finished workpiece discharge, minimizing manual intervention while maximizing production efficiency.

9. When operating in the integrated hot-and-cold bending mode, production begins immediately after process parameters are entered. The hydraulic ram does not need to return to its original position after each cycle. Instead, the lower forming die automatically rises approximately 100 mm, allowing rapid removal of the finished workpiece. This optimized process significantly shortens cycle time and improves overall production efficiency.
