Product Features:
1. High-Level Automation. The production line is equipped with an automated loading system (featuring a horizontal feeding channel and a rotating loading rack), an automated unloading system, and an automatic feeding mechanism. All drilling and steel stamping operations on the angle steel are performed in a single process on this line. The entire workflow is fully automated, eliminating the need for manual intervention and significantly reducing the labor intensity for operators.
2. The drilling spindle is equipped with a Taiwan BT40 precision spindle (including internal coolant), guaranteeing outstanding drilling efficiency and precision. The drilling unit is furnished with six CNC drilling heads, with three positioned on each wing of the angle steel. The corresponding heads on both sides are capable of simultaneously drilling holes of the same diameter and at identical distances from the upper ends of the angle steel wings.
3. The software features a bilingual Chinese/English interface, providing seamless operation and the ability to display workpiece drawings.
4. Programming is straightforward and efficient; users are required only to input the workpiece dimensions, hole diameter, spacing, and quantity when configuring the program. Alternatively, CAD/CAM lofting software can be used for direct file conversion. The system is fully compatible with NC1 files generated by TEKLA software.
5. Key hydraulic, pneumatic, and electrical components are sourced from well-established, high-quality brands.
6. The system includes an integrated self-diagnostic feature for fault detection.
7. The shearing unit is offered as an optional feature and utilizes a dual-blade cutting mechanism.
These specimens cover a variety of standard specifications and hole configurations of angle steel frequently used in the construction of transmission line towers. They enable potential users or inspectors to visually assess the operational capabilities of the equipment, offering concrete and direct references to determine whether the equipment satisfies the practical production requirements for transmission line tower manufacturing.
In the construction of ultra-high voltage (UHV) transmission lines, where transmission towers are exposed to extreme weather conditions and significant loads, this equipment plays a vital role in processing angle steel components for the towers' primary load-bearing structures. It efficiently performs drilling and stamping operations on angle steel used in tower bodies, cross-arms, and other essential structural components, ensuring precise dimensional accuracy and reliable connection integrity. Consequently, it supports the long-term structural strength and stability of the transmission towers throughout their service life.
