Product Features:
1. Advanced Automated Operation
This production line is fitted with a full-automatic material loading system consisting of horizontal feeding tracks and rotary loading frames, alongside automatic unloading devices and material conveying assemblies. All drilling and punching processes for angle steel are accomplished within one uninterrupted production cycle. The entire workflow runs fully unattended, which effectively cuts down labor costs, and meanwhile boosts production efficiency and equipment operational stability.
2. High-Accuracy Drilling Unit
The drilling spindle adopts high-grade Taiwan-made BT40 precision spindles, equipped with an internal cooling circuit to deliver superior drilling capability and outstanding dimensional precision. The drilling unit is outfitted with six CNC-driven drill heads, symmetrically arranged with three units on either side of the angle steel. For holes with uniform diameters and equal distances to the top edge of angle steel flanges, the paired drill heads on two sides can work concurrently, so as to optimize processing efficiency and overall output.
3. Intuitive Human-Machine Interface
The control system features dual-language support for Chinese and English. It delivers straightforward operation and presents workpiece drawings in a clear visual form.
4. Simplified Programming Process
Program setup is highly convenient. Operators merely need to enter workpiece sizes, hole diameters, hole pitches and production quantities. In addition, programs can be directly exported from CAD/CAM nesting software. The system is also compatible with .NC1 files generated by TEKLA software, realizing excellent interoperability and seamless workflow connection.
5. High-Quality Core Parts
Major hydraulic, pneumatic and electrical components are procured from renowned and credible suppliers, guaranteeing stable operation and extended service life of the equipment.
6. Built-In Fault Detection Function
The machine is integrated with a sophisticated self-diagnosis module, enabling rapid detection and resolution of operational malfunctions.
7. Optional Cutting Attachment
A customized shearing module is available as an optional accessory. It adopts cutting-edge double-blade shearing technology to achieve higher processing accuracy and working efficiency.
The above specimens cover mainstream standard specifications and hole layouts of angle steel widely applied in power transmission tower manufacturing. They allow potential clients and inspection personnel to conduct on-site verification and performance evaluation of the equipment, providing practical and visual references to judge whether the machine can satisfy the actual production requirements of transmission tower fabrication.
In ultra-high voltage (UHV) transmission line projects, power towers have to endure harsh external environments and heavy structural loads. This equipment plays an indispensable role in processing angle steel components that form the primary load-bearing structure of towers. It completes drilling and punching tasks for angle steel used in tower main bodies, cross arms and other core structural parts with high precision, and secures reliable connecting performance. Accordingly, the equipment helps enhance the overall structural stability, operational safety and long-term service performance of transmission towers during their whole lifecycle.
