Product Features:

1. The CNC angle steel punching system is available in two- or three-station configurations, with each punching station capable of accommodating three punch diameters. Punch locations are precisely controlled by the CNC system, enabling accurate machining of both round and slotted holes. Combined with high-speed material feeding and rapid punching cycles, the system significantly enhances production efficiency. When processing 50 × 50 × 4 mm angle steel, production capacity can reach approximately 9–10 tons per 8-hour shift.

2. The marking unit features a fully enclosed, high-rigidity structural design that provides outstanding stability during operation. Four cassette-type character holders are automatically selected through CNC programming, while marking positions can be adjusted according to specific production requirements. An optional 10-row rotary disc marking system enables automatic character indexing without manual adjustment, substantially increasing marking efficiency and overall productivity.

3. The shearing unit adopts a heavy-duty single-blade cutting mechanism that delivers high cutting force, excellent dimensional accuracy, and reliable cutting performance. The shearing process minimizes material waste while producing clean, burr-free cut surfaces. An open-access blade holder design allows quick, safe, and convenient blade replacement, reducing maintenance time and improving equipment availability.

4. The horizontal conveying system automatically transfers angle steel to the rotary loading mechanism via a motor-driven reduction gearbox. This arrangement ensures stable material positioning before feeding and enables smooth, continuous workpiece transportation throughout the entire production cycle.

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

6. The punching, marking, and shearing units are powered by a high-performance hydraulic system equipped with a high-speed hydraulic power station and accumulator. Ferrule-type hydraulic pipe fittings ensure reliable, leak-free performance while simplifying maintenance. The hydraulic manifold incorporates premium Atos valve blocks, providing stable hydraulic pressure, dependable system performance, and an extended service life.

7. To accommodate a wide range of production environments, the hydraulic system supports multiple cooling methods, including water cooling, air cooling, and oil cooling. Users can select the most appropriate cooling configuration based on specific operating conditions and manufacturing requirements.

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