Product Features:
1. The machine is equipped with a sophisticated CNC control platform integrated with a PLC system and an intuitive touchscreen HMI. This architecture enables efficient data input, real-time process supervision, and streamlined production management, ensuring stable operation, enhanced productivity, and simplified user interaction during routine manufacturing activities.
2. The equipment utilizes advanced ultrasonic-frequency induction heating technology, delivering superior thermal efficiency and environmentally sustainable operation. This innovative heating solution increases production throughput, minimizes operating costs, and fully complies with modern environmental protection and energy-efficiency standards.
3. Engineered as a complete manufacturing solution, the system eliminates the requirement for auxiliary tooling and frequent mold adjustments. This integrated design reduces setup time, simplifies workflow management, and significantly improves overall production efficiency.
4. By leveraging advanced CNC control technology, the machine achieves highly accurate and repeatable bending operations, ensuring consistent product quality, superior dimensional control, and enhanced manufacturing productivity.
5. The machine incorporates a dedicated hydraulic power unit integrated with a comprehensive electrical control system. This configuration provides convenient operation, dependable performance, enhanced operational safety, and excellent suitability for continuous industrial production environments.
6. The cold-bending process is applicable to angle steel sections up to L100×L100×10 mm when the required bending angle does not exceed 5°. This process ensures controlled material deformation while maintaining dimensional accuracy and structural integrity.
7. Under normal production conditions, cold-forming operations require approximately 10 seconds per workpiece, while thermal bending typically takes around 120 seconds per component, depending on material grade and workpiece dimensions. Thermal forming is initiated once the material reaches approximately 800°C (red-hot condition), with process parameters adjusted according to material characteristics and specified bending requirements.
8. For thermal bending operations, operators preset the required processing parameters and activate the cycle using either the start button or foot pedal. The machine then automatically performs the complete processing sequence, including material positioning within the heating area, induction heating, heating unit withdrawal, workpiece clamping and forming, ram return, and finished-part unloading.
9. When operating in combined thermal and cold-forming mode, production can commence immediately after parameter configuration. The forming ram is not required to return to its original position; instead, the lower forming die automatically rises to create approximately 100 mm of clearance for convenient workpiece removal. This optimized process significantly improves productivity and reduces overall cycle time.
The demonstration workpieces produced by the angle steel punching, shearing, and marking production line conform to the standard specifications and processing criteria widely adopted within the transmission tower manufacturing industry. These samples provide customers, engineers, and inspection personnel with a practical means of evaluating machining precision, finished-product quality, and overall production performance, clearly demonstrating the equipment’s ability to satisfy demanding tower fabrication requirements.
In ultra-high-voltage (UHV) transmission line construction projects, transmission towers are required to withstand harsh environmental conditions and substantial structural loading. This equipment plays a critical role in processing the angle steel components that form the primary load-bearing framework of these structures. The system performs high-precision drilling and marking operations on angle steel used in tower bodies, cross-arms, and other key structural members, ensuring exceptional dimensional accuracy and reliable assembly performance. Consequently, it contributes significantly to the structural integrity, service life, and operational safety of transmission towers, supporting the reliable and continuous operation of UHV power transmission networks.
