Product Features:

1. The CNC angle steel punching system is available in two- or three-station configurations, with each punching station accommodating three different punch diameters. Punching coordinates are precisely programmed and controlled through the CNC system, enabling accurate machining of both round and slotted holes. Combined with high-speed material feeding and optimized punching cycles, the system significantly enhances overall production efficiency. When processing 50 × 50 × 4 mm angle steel, the production capacity can reach approximately 9–10 tons during an 8-hour working shift.

2. The marking unit adopts a fully enclosed, high-strength structural design, providing superior rigidity and stable operating performance. Four cassette-type character holders are automatically selected according to CNC-programmed instructions, while marking positions can be freely configured based on specific production requirements. An optional 10-row rotary-disc marking mechanism enables automatic character indexing without manual intervention, substantially increasing marking efficiency and overall production capacity.

3. The shearing unit features a heavy-duty single-blade cutting structure, offering high cutting capacity, accurate dimensional control, and stable shearing performance. Its optimized cutting process minimizes material waste while delivering smooth and clean cut surfaces with reduced burr formation. The open blade-holder design allows convenient access for fast and secure blade replacement, thereby reducing maintenance downtime and improving equipment availability.

4. The horizontal material conveying system automatically transfers angle steel to the rotary loading mechanism through a motor-driven reduction gearbox. This arrangement maintains stable workpiece alignment before feeding and ensures smooth, reliable, and continuous material 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 positional feedback through a fully closed-loop control system, ensuring highly accurate material feeding, precise positioning, and excellent repeatability throughout the machining process.

6. The punching, marking, and shearing units are powered by a high-performance hydraulic system equipped with a high-speed hydraulic power unit and accumulator. Ferrule-type hydraulic fittings provide reliable, leak-resistant connections while simplifying routine servicing and maintenance. The hydraulic manifold incorporates high-quality Atos valve blocks, delivering stable pressure regulation, dependable hydraulic performance, and extended service life.

7. To accommodate varying operating conditions, the hydraulic system supports multiple cooling configurations, including water cooling, air cooling, and oil cooling. The most suitable cooling solution can be selected according to the customer's operating conditions, installation environment, and specific production requirements.

8. The control platform integrates an industrial computer, PLC controller, servo drive system, and external sensing devices to establish a comprehensive CNC control architecture. After the required machining parameters are entered, the software automatically generates the corresponding 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, high-capacity program storage, real-time position monitoring, and comprehensive fault-diagnostic functions, significantly improving production supervision, equipment management, and overall operating efficiency.

The demonstration samples cover standard angle steel specifications and representative machining applications commonly utilized in power transmission tower manufacturing. These typical workpieces enable customers, engineers, and quality-control personnel to directly assess machining accuracy, processing quality, dimensional consistency, and overall equipment performance. They therefore provide practical and reliable references for evaluating the machine's processing capabilities and determining its suitability for diverse production requirements.

In Ultra-High-Voltage (UHV) power transmission projects, transmission towers are required to withstand demanding environmental conditions and considerable structural loads. This production line plays an important role in manufacturing the angle steel components that form the primary load-bearing structure of these towers. It efficiently carries out high-precision punching and drilling operations on angle steel used for tower bodies, cross-arms, and other essential structural members, ensuring accurate hole positioning, reliable structural connections, and consistent component dimensions. As a result, the system contributes to improved structural integrity, operational safety, and long-term service reliability of transmission towers, while providing an efficient and dependable manufacturing solution for high-volume production in modern power transmission infrastructure.
