Product Features:
1. The CNC angle steel punching machine is equipped with two to three punching stations, each capable of accommodating three distinct punch diameter specifications. All punching stations utilize fully CNC-programmable control to ensure consistent and precise positioning throughout the punching process. The machine is capable of processing both round and slotted holes to satisfy a wide range of operational requirements. Featuring high-speed feeding and punching mechanisms, the equipment achieves substantially enhanced production efficiency. When processing 50×50×4mm angle steel, the daily output can reach 9 to 10 tons during an 8-hour working shift.
2. The marking module of the CNC angle steel processing machine is mounted on a high-rigidity integrated frame structure. The marking system incorporates four cassette assemblies, enabling automatic program-driven switching and full-range adjustment of character positions. Additionally, the equipment features a 10-station rotary disc marking mechanism, achieving fully automatic character selection without manual intervention, thereby significantly improving marking efficiency and overall productivity.
3. The CNC angle steel cutting unit employs a single-blade shearing configuration with superior cutting performance. The cutting process achieves zero material wastage while delivering smooth surfaces and high dimensional accuracy. The blade assembly is designed with an open-access door structure, facilitating safe, convenient, and rapid blade replacement and routine maintenance.
4. The transverse conveying platform utilizes a motor-and-gearbox drive system to reliably transfer angle steel workpieces to the rotary conveying frame. This design ensures stable positioning of workpieces on the feeding conveyor and guarantees continuous, uninterrupted operation of downstream production processes.
5. Workpieces are securely clamped and precisely conveyed by the CNC feeding trolley to maintain accurate positioning throughout all machining procedures. The feeding trolley is powered by a high-performance servo motor and incorporates a photoelectric encoder feedback system, forming a fully closed-loop control system to ensure high-precision feeding and positioning.
6. The CNC angle steel punching and marking machine employs a hydraulic drive system to perform punching, marking, and cutting operations. It is equipped with a high-efficiency hydraulic power unit integrated with an energy-storage accumulator. All hydraulic lines feature ferrule-type connectors, providing reliable sealing and convenient disassembly for maintenance and replacement. The core hydraulic manifold blocks are supplied by the internationally recognized brand Atos, ensuring stable operation and long-term reliability of the hydraulic system.
7. The hydraulic power unit supports multiple cooling methods, including water cooling, air cooling, and oil chiller cooling. Customers can select the most suitable cooling solution based on actual on-site production conditions and operational requirements.
8. The core control system comprises an industrial computer, PLC controller, servo drive units, external sensor switches, and other essential components. Upon inputting machining parameters, the system automatically generates corresponding machining programs. It supports widely used file formats, including DXF and NC exported from CAD design software. The industrial computer is equipped with a user-friendly human-machine interface, enabling intuitive operation and real-time process monitoring. The system integrates multiple functional modules, including graphical workpiece display, mass data management, positioning status visualization, and automatic fault alert notifications.
The processed sample workpieces conform to mainstream industry specifications and the general processing requirements of the angle steel tower sector, providing clients with a clear demonstration of the equipment’s machining accuracy, processing quality, and manufacturing capabilities. These samples serve as reliable benchmarks for evaluating equipment performance and production adaptability, supporting objective and informed investment decisions.
In the construction of ultra-high-voltage (UHV) transmission lines, power towers must endure extreme environmental conditions and substantial mechanical loads. This professional-grade processing equipment functions as a core production facility for machining angle steel components of main tower structures, delivering highly efficient and precision-engineered processing solutions for UHV tower manufacturing projects.
