Product Features:
1. The CNC angle steel punching machine is outfitted with two or three punching units, each capable of accommodating three distinct punch sizes. These units are precisely regulated through numerical control (NC), ensuring accurate positioning throughout the punching process. The machine is designed to produce both circular and oval holes. With its high-speed feeding and punching capabilities, it substantially enhances production efficiency. For 50×50×4mm angle steel, the machine can achieve a production output of 9–10 tons per eight-hour shift.
2. The marking unit of the CNC angle punching machine is enclosed within a sturdy and durable housing. The marking system incorporates four cassette sets, selectable via programming, providing flexibility in adjusting the marking positions. Moreover, the machine utilizes a disc marking method with 10 rows, automatically selecting characters without manual intervention, thereby significantly improving marking efficiency.
3. The CNC angle steel cutting machine features a single-blade shearing unit, recognized for its exceptional cutting force. Each cut is performed with zero material wastage, producing a clean and smooth cut surface. The blade housing is designed with an open-door mechanism, allowing for rapid and safe blade replacement.
4. The horizontal material table efficiently conveys the angle steel to the motor- and reducer-driven rotary material rack. This system ensures precise positioning of the angle steel onto the feeding conveyor for subsequent processing.
5. The workpiece is firmly clamped and advanced by a CNC feeding carriage, guaranteeing accurate alignment and positioning. The feeding carriage is powered by a servo motor and incorporates feedback from a photoelectric encoder, operating within a closed-loop control system to enhance precision.
6. The CNC angle steel punching and marking machine is powered by a hydraulic system that drives the punching, marking, and shearing operations. It is fitted with a high-speed hydraulic station equipped with an accumulator, and the hydraulic lines utilize ferrule-type fittings, ensuring leak-free performance while facilitating maintenance and component replacement. The main hydraulic valve blocks are sourced from the reputable Atos brand, providing a dependable and high-performance hydraulic system.
7. The hydraulic station incorporates a versatile cooling system, offering options such as water cooling, air cooling, or oil chilling. This flexibility allows customers to select the most appropriate cooling method to meet their specific operational requirements.
8. The control system comprises an upper-level computer, PLC, servo motor, external detection switches, and other essential components. The operator simply inputs the processing parameters, and the system automatically generates the corresponding machining program. It offers full compatibility with a variety of file formats, including DXF, NC, and other CAD-generated files. The upper computer’s human-machine interface is highly intuitive, providing a clear display and streamlined operation. Key features include graphical visualization of workpieces, extensive data storage, real-time position monitoring, and fault alarm notifications.
These samples, reflecting standard specifications and typical processing parameters within the angle steel tower sector, enable users to directly assess the equipment’s processing quality, accuracy, and workmanship. They serve as a concrete reference for evaluating the machine’s performance and its suitability for specific production requirements, thereby facilitating informed, data-driven decisions for potential applications.
In the construction of ultra-high voltage (UHV) transmission lines, where towers are subjected to extreme weather conditions and heavy loads, this equipment plays a vital role in processing the angle steel components that form the primary structural framework of the towers. It efficiently executes drilling and stamping operations on the angle steel used in tower bodies, cross-arms, and other essential structural elements, ensuring precise dimensions and secure connections that maintain the overall stability and structural integrity of the towers.
