Product Features:
1. The equipment is equipped with a sophisticated CNC control system integrated with a PLC controller and an intuitive touchscreen Human–Machine Interface (HMI). This configuration allows convenient program entry, real-time process monitoring, and efficient production management, ensuring reliable machine performance and simplified daily operation.
2. The machine adopts advanced ultrasonic-frequency induction heating technology, providing fast, energy-efficient, and environmentally friendly heating performance. This innovative solution improves production efficiency, reduces operating costs, and complies with modern environmental protection and sustainability requirements.
3. Designed as a multifunctional forming system, the machine eliminates the need for additional tooling or frequent mold replacement. This integrated design simplifies production setup, shortens preparation time, and enhances overall manufacturing efficiency.
4. By utilizing advanced CNC positioning technology, the system delivers accurate and repeatable bending performance, ensuring consistent product quality while improving production capacity and process stability.
5. The machine incorporates an independent hydraulic power unit integrated with a comprehensive electrical control system. This configuration offers convenient operation, reliable performance, enhanced operational safety, and excellent suitability for continuous industrial production.
6. The cold bending function is designed for angle steel sections up to L100 × L100 × 10 mm, provided the bending angle does not exceed 5°. This capability ensures precise forming while maintaining dimensional consistency and minimizing material deformation.
7. Under normal operating conditions, the cold-forming cycle requires approximately 10 seconds per workpiece, while thermal bending typically requires approximately 120 seconds, depending on material characteristics and workpiece dimensions. Thermal forming begins once the workpiece reaches approximately 800°C (red-hot condition), with heating parameters optimized according to material properties and required bending specifications.
8. After processing parameters have been configured, operators can initiate the automatic cycle using either the start button or foot pedal. The system then automatically completes the entire forming sequence, including workpiece positioning, induction heating, withdrawal of the heating assembly, hydraulic forming, ram return, and finished workpiece unloading.
9. When operating in the combined thermal and cold-forming mode, production begins immediately after parameter input. The hydraulic ram is not required to return to its initial position. Instead, the lower forming die automatically rises approximately 100 mm, allowing rapid workpiece removal and significantly improving production efficiency while reducing cycle time.
The demonstration workpieces produced by the angle steel punching, marking, and cutting production line are manufactured in accordance with the standard specifications and processing requirements widely adopted in the transmission tower industry. These samples provide customers and inspection personnel with a practical reference for evaluating machining precision, finished-product quality, and overall processing performance, clearly demonstrating the equipment's ability to satisfy the stringent manufacturing standards required for transmission tower fabrication.
In ultra-high-voltage (UHV) power transmission projects, where transmission towers must withstand severe environmental conditions and substantial structural stresses, this equipment serves a vital role in processing the angle steel members that form the primary load-bearing structure of the towers. The system performs precise drilling and marking operations on components used in tower bodies, cross-arms, and other critical structural assemblies, ensuring excellent dimensional consistency and structural reliability. As a result, it contributes significantly to the strength, durability, and long-term operational safety of transmission towers, supporting the stable and uninterrupted performance of UHV power transmission infrastructure.
