Product Features:

1. The CNC angle steel punching system is available in two-station or three-station configurations, with each punching station supporting three different punch diameters. The CNC control system precisely manages punching positions, enabling accurate processing of both circular holes and slotted holes. By combining high-speed material feeding with efficient punching cycles, the system greatly improves production productivity. When processing 50 × 50 × 4 mm angle steel, the equipment can achieve an output capacity of approximately 9–10 tons within an 8-hour working shift.

2. The marking unit adopts a fully enclosed, high-strength structural design to ensure excellent rigidity, stability, and operational reliability. Four cassette-type character sets are automatically selected through CNC programming, while marking locations can be flexibly adjusted according to different production requirements. An optional 10-row rotary disc marking mechanism enables automatic character selection and indexing without manual intervention, significantly improving marking speed and overall production efficiency.

3. The shearing module utilizes a heavy-duty single-blade cutting structure, providing strong cutting capability, high dimensional accuracy, and stable cutting performance. The optimized shearing process effectively reduces material waste while producing smooth and clean cutting surfaces without burrs. The open-type blade mounting design allows fast, convenient, and safe blade replacement, reducing maintenance time and improving equipment utilization.

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

5. Workpieces are firmly clamped and transferred by a servo-driven CNC feeding carriage. A high-precision photoelectric encoder provides continuous position feedback through a closed-loop control system, ensuring excellent feeding accuracy, precise positioning performance, and outstanding repeatability during machining operations.

6. The punching, marking, and shearing modules are driven by a high-performance hydraulic system equipped with a rapid-response hydraulic power unit and accumulator. Ferrule-type hydraulic fittings provide reliable sealing performance, prevent leakage, and simplify system maintenance. The hydraulic manifold is equipped with premium Atos valve blocks, ensuring stable hydraulic operation, dependable performance, and extended equipment service life.

7. To meet different production conditions and operating environments, the hydraulic system supports multiple cooling solutions, including water cooling, air cooling, and oil cooling. Users can select the most suitable cooling method according to specific application requirements, ensuring stable hydraulic performance during continuous operation.

8. The control platform integrates an industrial computer, PLC controller, servo drive system, and external sensing components to create a comprehensive CNC control architecture. After machining parameters are entered, the system automatically generates the required processing programs. It supports direct import of DXF, NC, and other CAD-generated file formats. The intuitive Human–Machine Interface (HMI) provides graphical workpiece display, extensive program storage capacity, real-time position monitoring, and intelligent fault diagnosis functions, significantly improving production management efficiency and operational convenience.

The demonstration samples include standard angle steel profiles and representative machining applications commonly used in power transmission tower manufacturing. These sample components enable customers, engineers, and quality inspection personnel to directly evaluate machining accuracy, processing quality, dimensional consistency, and overall production performance. They provide practical verification of the equipment’s processing capability and demonstrate its suitability for diverse industrial manufacturing requirements.

In Ultra-High-Voltage (UHV) power transmission projects, transmission towers are required to withstand severe environmental conditions and significant structural loads throughout their service life. This production line plays an essential role in manufacturing the angle steel components that form the primary load-bearing framework of transmission towers. The equipment performs high-precision punching and drilling operations on angle steel members used for tower bodies, cross-arms, and other critical structural components, ensuring accurate hole positioning, reliable connection performance, and excellent dimensional consistency. As a result, the system effectively enhances the structural strength, operational safety, and long-term reliability of transmission towers while providing an efficient and dependable manufacturing solution for large-scale production in modern power transmission infrastructure projects.
