Product Features:

1. The CNC angle steel punching system is offered in two-station or three-station configurations, with each punching station supporting three distinct punch diameters. Punching coordinates are accurately programmed and managed through the CNC control system, enabling precise processing of both round and slotted holes. Combined with high-speed material feeding and optimized punching cycles, the system substantially improves overall production efficiency. When processing 50 × 50 × 4 mm angle steel, the production capacity can reach approximately 9–10 tons per 8-hour working shift.

2. The marking unit adopts a fully enclosed, high-strength structural configuration, delivering excellent rigidity and stable operational performance. Four cassette-type character holders are automatically selected according to CNC-programmed commands, while marking positions can be flexibly defined based on specific manufacturing requirements. An optional 10-row rotary disc marking mechanism supports automatic character indexing without manual operation, significantly improving marking productivity and overall production capacity.

3. The shearing unit incorporates a heavy-duty single-blade cutting mechanism, providing substantial cutting capacity, precise dimensional control, and consistent shearing performance. Its optimized cutting process reduces material waste while producing smooth, clean cut surfaces with minimal burr formation. The open blade-holder configuration enables convenient access for rapid and secure blade replacement, reducing maintenance-related downtime and improving equipment availability.

4. The horizontal material conveying system automatically delivers angle steel to the rotary loading mechanism through a motor-driven reduction gearbox. This configuration maintains consistent workpiece alignment before feeding and ensures smooth, dependable, and continuous material transportation throughout the complete production cycle.

5. Workpieces are securely clamped and conveyed by a servo-actuated CNC feeding carriage. A photoelectric encoder continuously supplies positional feedback through a fully closed-loop control architecture, ensuring highly accurate material feeding, precise positioning, and excellent repeatability throughout the machining operation.

6. The punching, marking, and shearing units are driven by a high-performance hydraulic system incorporating a high-speed hydraulic power unit and accumulator. Ferrule-type hydraulic fittings provide secure, leak-resistant connections while facilitating routine inspection and maintenance. The hydraulic manifold is equipped with high-quality Atos valve blocks, ensuring stable pressure control, reliable hydraulic operation, and extended component service life.

7. To support different operating conditions, the hydraulic system offers multiple cooling options, including water cooling, air cooling, and oil cooling. The appropriate cooling configuration 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. Once the required machining parameters have been 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 enhancing production supervision, equipment management, and overall operational 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.
