Product Features:
1. The CNC angle steel punching machine is fitted with two or three punching stations, with each station designed to hold three different punch diameters. All punching stations are operated under CNC control to guarantee precise positioning throughout the punching process. The equipment is capable of processing both round and slotted holes. Featuring high-speed feeding and punching performance, the machine substantially improves production productivity. For 50×50×4mm angle steel, the processing capacity can achieve approximately 9–10 tons within an eight-hour working shift.
2. The marking section of the CNC angle steel punching machine is integrated into a robust and highly rigid frame structure. The marking system is composed of four cassette groups, which can be automatically selected through programmed control, with character positions fully adjustable. In addition, the machine adopts a 10-line rotary disc marking system that enables automatic character selection without manual operation, significantly enhancing marking productivity and operational efficiency.
3. The CNC angle steel cutting machine adopts a single-blade shearing system, offering outstanding cutting capability. The cutting process generates no material scrap, while ensuring a clean and highly precise cutting finish. The blade assembly is designed with an open-access door structure, allowing convenient and secure blade replacement.
4. The transverse conveying table transfers the angle steel smoothly onto the rotary conveying rack through a motor and gearbox drive system. This mechanism ensures stable placement of the angle steel onto the feeding conveyor for continuous downstream operations.
5. The workpiece is securely held and transported by the CNC feeding carriage, ensuring accurate positioning throughout the processing cycle. The feeding carriage is powered by a servo drive motor and monitored by a photoelectric encoder feedback system, operating within a fully closed-loop control configuration.
6. The CNC angle steel punching and marking machine utilizes a hydraulic drive system to perform punching, marking, and cutting functions. It is equipped with a high-efficiency hydraulic power unit integrated with an accumulator system. The hydraulic pipelines adopt ferrule-type connectors, ensuring excellent sealing performance while allowing easy replacement and maintenance. The primary hydraulic manifold blocks are supplied by the renowned Atos brand, ensuring stable operation and high reliability of the hydraulic system.
7. The hydraulic power unit supports various cooling configurations, including water cooling, air cooling, and oil chiller cooling systems. Customers may choose the most appropriate cooling solution according to their actual production conditions and operational demands.
8. The control system mainly consists of an industrial computer, PLC system, servo drive motors, external sensing switches, and other key components. After the operator enters the processing specifications, the system automatically creates the required machining program. It is also compatible with DXF, NC, and other file formats exported from CAD software. The industrial computer is equipped with a user-friendly human-machine interface, enabling straightforward operation and clear process monitoring. The system provides functions including graphical workpiece visualization, extensive data management, position tracking display, and automatic fault alarm indication.
These samples, which reflect standard specifications and common processing requirements in the angle steel tower industry, enable users to directly evaluate the equipment’s machining accuracy, processing quality, and manufacturing standards. They provide a practical basis for assessing the machine’s operational performance and suitability for specific production applications, thereby assisting customers in making accurate and well-informed investment decisions.
In the construction of ultra-high-voltage (UHV) transmission lines, where towers are required to withstand severe environmental conditions and heavy structural loads, this equipment plays a crucial role in processing the angle steel components used in the main tower framework. It performs high-efficiency drilling and punching operations on the angle steel applied to tower bodies, cross-arms, and other key structural sections, ensuring precise dimensions and reliable joint connections that maintain the overall strength, stability, and structural reliability of the towers.
