Product Features:
1. Control System & User Interface. The machine is equipped with an advanced Computer Numerical Control (CNC) system integrated with a Programmable Logic Controller (PLC) and a user-friendly touchscreen Human-Machine Interface (HMI). This configuration enables convenient program input, real-time process monitoring, and efficient operational management, ensuring reliable performance and simplified operation throughout daily production activities.
2. Innovative Heating Technology. The equipment incorporates intelligent ultrasonic-frequency induction heating technology, a highly efficient and environmentally responsible solution that enhances production productivity, lowers operating expenses, and complies with relevant environmental regulations and sustainability requirements.
3. Comprehensive Manufacturing Solution. Designed as an all-in-one production system, the machine eliminates the need for supplementary tooling or frequent mold modifications, reducing setup complexity while streamlining manufacturing processes and improving overall operational efficiency.
4. High-Accuracy CNC Forming. Utilizing advanced Computer Numerical Control (CNC) technology, the system delivers precise and repeatable bending performance, ensuring consistent product quality while maximizing manufacturing productivity and process reliability.
5. Integrated Hydraulic and Electrical System. The equipment features a self-contained hydraulic unit seamlessly combined with an integrated electrical control system. This design offers straightforward operation, dependable performance, enhanced safety, and suitability for continuous high-capacity production environments.
6. Cold-Bending Capability. The cold-forming function is suitable for angle steel sections up to L100×L100×10 mm, provided that the bending angle remains within 5 degrees. This capability ensures controlled deformation and maintains dimensional accuracy throughout the bending process.
7. Production Cycle Efficiency. Under standard operating conditions, cold-bending operations typically require approximately 10 seconds per workpiece, while thermal bending cycles average around 120 seconds per component, depending on material specifications and part dimensions. Thermal forming is initiated only after the workpiece reaches approximately 800°C (red-hot condition), with processing parameters optimized according to material properties and required bending tolerances.
8. Thermal Bending Process Sequence. During thermal bending operations, once the processing parameters have been established, the automated cycle can be activated via the start button or foot switch. The system then executes a predefined sequence, including workpiece positioning within the heating zone, controlled heating, automatic withdrawal of the heating unit, clamping and forming of the material, ram retraction, and final unloading of the completed component.
9. Combined Thermal and Cold-Forming Operation. In the integrated thermal and cold-forming mode, production can begin immediately after process parameters are entered. The pressure ram is not required to return to its initial position; instead, the lower forming die rises to provide a clearance of approximately 100 mm, allowing convenient part removal. This optimized workflow significantly improves productivity and shortens overall processing time.
The trial workpieces produced by the angle steel punching, cutting, and marking line are manufactured in accordance with the standard specifications and processing requirements commonly adopted within the angle steel tower industry. These samples provide customers with a practical reference for evaluating machining accuracy, finished-product quality, and overall manufacturing performance, demonstrating the equipment’s capability to meet the rigorous standards of tower fabrication applications.
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.
