Product Features:
1. Control System & Interface. The system is integrated with a Computer Numerical Control (CNC) system combined with a Programmable Logic Controller (PLC), along with an intuitive touchscreen HMI, enabling efficient data entry and real-time monitoring of operational parameters. This configuration ensures stable, efficient, and user-friendly operation during standard production processes.
2. Advanced Heating Technology. The machine utilizes intelligent ultrasonic-frequency induction heating technology, an advanced solution that significantly improves production efficiency, reduces overall manufacturing costs, and fully complies with applicable environmental protection standards and regulations.
3. Integrated Production Solution. As a fully integrated system, the equipment eliminates the requirement for additional tooling or mold adjustments, thereby simplifying installation procedures and optimizing overall production workflow efficiency.
4. Precision CNC Bending. Leveraging Computer Numerical Control (CNC) technology, the system performs highly accurate bending of workpieces, consistently upholding stringent product quality standards while improving overall production efficiency.
5. Integrated Hydraulic Control. The machine features a self-contained hydraulic system combined with an integrated electrical control unit, providing intuitive and user-friendly operation, ensuring safe and reliable performance, and supporting the requirements of high-volume manufacturing.
6. Cold-Pressing Capability. The cold-pressing process is applicable to angle steel components with dimensions up to L100×L100×10 mm, as long as the bending angle does not exceed 5 degrees, ensuring precise and controlled deformation.
7. Processing Cycle Times. The typical cycle time for cold-pressing operations is 10 seconds per workpiece, whereas the thermal bending process requires approximately 120 seconds per unit, depending on the material grade and component dimensions. Thermal forming begins only once the workpiece reaches a temperature of 800°C (red-hot stage), with precise process parameters established based on the specific material characteristics and the required bending angle tolerances.
8. Thermal Processing Operation Sequence. During the thermal processing stage, once the operating parameters are set, the cycle can be initiated by pressing the start button or actuating the foot pedal, triggering a fully automated sequence. The process follows a predefined workflow, including feeding the workpiece into the heating zone, applying thermal energy, retracting the heating assembly upon completion, clamping and compressing the workpiece, lifting the ram, and finally unloading and retrieving the finished component.
9. Combined Thermal and Cold-Pressing Operation. In the integrated thermal processing and cold-pressing mode, once the process parameters are configured, cold-pressing can commence immediately. The pressure ram is not required to return to its home position; instead, the lower pressing die is raised to provide a 100 mm clearance, facilitating convenient workpiece removal. This optimized operational sequence substantially enhances overall process efficiency.
These trial specimens, produced using the angle steel punching, cutting, and marking machinery, conform to the standard specifications and processing parameters widely employed in the angle steel tower industry. They offer users a direct means to evaluate the machine’s processing precision, quality, and workmanship—critical performance metrics that confirm the equipment’s ability to satisfy the stringent operational demands of angle steel tower fabrication.
In the construction of ultra-high-voltage (UHV) transmission lines, where towers are subjected to extreme environmental conditions and heavy structural loads, this equipment plays a critical role in processing the angle steel components that constitute the primary load-bearing framework of the towers. It reliably performs drilling and stamping operations on the angle steel used in tower bodies, cross-arms, and other essential structural elements, ensuring high dimensional accuracy and robust structural integrity. This capability enhances the overall durability of the transmission towers, which is essential for the safe, reliable, and uninterrupted operation of UHV power transmission networks.
