Product Features:
1. Advanced Automation. The production line is outfitted with an automatic loading system (incorporating a horizontal feeding channel and a rotating loading rack), an automatic unloading system, and an automatic feeding mechanism. All drilling and steel stamping operations on the angle steel are carried out in a single process on this line. The entire workflow is fully automated, removing the need for manual involvement and thereby greatly reducing the labor intensity for operators.
2. The drilling spindle is fitted with a Taiwan BT40 precision spindle (featuring internal coolant), ensuring exceptional drilling efficiency and accuracy. The drilling unit is equipped with six CNC drilling heads, with three located on each wing of the angle steel. The corresponding heads on both sides can simultaneously drill holes of the same diameter and at identical intervals from the upper ends of the angle steel wings.
3. The software is equipped with a bilingual Chinese/English interface, ensuring intuitive operation and the capability to display workpiece drawings.
4. Programming is simple and efficient; users need only input the workpiece dimensions, hole diameter, spacing, and quantity when creating the program. Alternatively, CAD/CAM lofting software can be utilized for direct file conversion. The system is fully compatible with NC1 files generated by TEKLA software.
5. Essential hydraulic, pneumatic, and electrical components are procured from reputable, high-performance brands.
6. The system is integrated with a self-diagnostic feature for failure detection.
7. The shearing unit is available as an option and employs a dual-blade cutting system.
These specimens encompass a range of standard specifications and hole configurations of angle steel commonly utilized in the construction of transmission line towers. They allow prospective users or inspectors to visually evaluate the operational performance of the equipment, providing clear and tangible references to assess whether the equipment meets the practical production needs of transmission line tower manufacturing.
In the construction of ultra-high voltage (UHV) transmission lines, where transmission towers endure extreme weather conditions and substantial loads, this equipment plays an integral role in processing angle steel components for the towers' primary load-bearing structures. It efficiently carries out drilling and stamping operations on angle steel used in tower bodies, cross-arms, and other critical structural elements, ensuring precise dimensional accuracy and reliable connection performance. As a result, it contributes to the long-term structural integrity and stability of the transmission towers throughout their operational lifespan.
