Product Features:

1. The CNC angle steel punching system is available in configurations with two or three punching units, each capable of accommodating three punch diameters. Punch locations are precisely controlled by the CNC system, enabling accurate production of both circular and slotted holes. The combination of high-speed material feeding and rapid punching significantly improves production efficiency. When processing 50 × 50 × 4 mm angle steel, the system achieves an output of approximately 9–10 tons per 8-hour working shift.

2. The marking unit adopts a fully enclosed, high-strength structural design to ensure excellent rigidity and operational stability. Four cassette-type character sets are automatically selected through CNC programming, while marking positions can be flexibly adjusted to suit different processing requirements. An optional 10-row rotary disc marking system provides automatic character indexing without manual intervention, substantially increasing marking speed and production productivity.

3. The shearing module incorporates a heavy-duty single-blade cutting mechanism, delivering high cutting force, superior dimensional precision, and stable cutting performance. The shearing process minimizes material waste while producing smooth, burr-free cut surfaces. An open-access blade holder design allows fast, safe, and convenient blade replacement, reducing maintenance time.

4. The horizontal conveying system automatically transfers angle steel to the rotary loading device through a motor-driven reduction gearbox. This configuration ensures stable material positioning before feeding and enables continuous, reliable workpiece transportation throughout the entire production process.

5. Workpieces are securely clamped and transported by a servo-driven CNC feeding carriage. A photoelectric encoder provides real-time position feedback within a fully closed-loop control system, ensuring outstanding feeding accuracy, precise positioning, and excellent repeatability during machining operations.

6. The punching, marking, and shearing functions are powered by a high-performance hydraulic system equipped with a high-speed hydraulic power station and accumulator. Hydraulic pipelines utilize ferrule-type fittings to provide reliable leak-free operation while facilitating convenient maintenance. The hydraulic manifold is equipped with premium Atos valve blocks, ensuring stable hydraulic performance, dependable operation, and extended equipment service life.

7. To satisfy diverse production requirements, the hydraulic system supports multiple cooling configurations, including water cooling, air cooling, and oil cooling. Customers can select the most appropriate cooling solution according to specific operating environments and production conditions.

8. The control platform integrates an industrial computer, PLC controller, servo drive system, and external sensing devices into a comprehensive CNC control system. After machining parameters are entered, the software automatically generates processing programs. The system supports direct import of DXF, NC, and other CAD-generated file formats. Its intuitive Human–Machine Interface (HMI) provides graphical workpiece display, large-capacity program storage, real-time position monitoring, and comprehensive fault diagnostic functions, greatly improving production management efficiency.

The demonstration samples represent standard angle steel specifications and typical machining applications widely used in power transmission tower fabrication. These representative workpieces allow customers, engineers, and quality inspectors to directly evaluate machining precision, processing quality, dimensional consistency, and overall manufacturing performance. They provide reliable practical references for assessing the equipment's capabilities and verifying its suitability for a wide range of production requirements.

In Ultra-High-Voltage (UHV) power transmission projects, where transmission towers must withstand extreme environmental conditions and substantial structural loading, this production line serves a critical role in manufacturing the angle steel components that constitute the towers' primary load-bearing framework. The equipment efficiently performs high-precision punching and drilling operations on angle steel used for tower bodies, cross-arms, and other critical structural members, ensuring accurate hole positioning, dependable connection quality, and excellent dimensional consistency. Consequently, the system significantly improves the structural integrity, operational safety, and long-term service reliability of transmission towers while providing an efficient manufacturing solution for large-scale production in modern power transmission infrastructure.
