Product Features:
1. The CNC angle steel punching machine is equipped with two or three punching units, each capable of accommodating three different punch sizes. These punching units are precisely controlled via numerical control (NC) to ensure accurate positioning during punching operations. The machine is capable of executing both circular and oval hole punching. Its high-speed feeding and punching functions significantly enhance production efficiency. For 50×50×4mm angle steel, the production output can reach 9–10 tons over an eight-hour shift.
2. The marking unit of the CNC angle steel punching machine is housed within a sturdy and rigid frame. The marking system consists of four cassette sets, which can be selected through programming, with fully adjustable typing positions. Additionally, a 10-row disc marking method is available, automatically selecting characters without manual intervention, thereby greatly improving marking efficiency.
3. The CNC angle steel cutting machine is equipped with a single-blade shearing module, recognized for its superior cutting force. Each cut is performed with zero material waste, delivering a smooth and highly accurate cut surface. The blade housing features an open-door design, facilitating quick and safe blade replacement.
4. The horizontal material table efficiently transfers the angle steel to the rotary material rack, powered by a motor and reducer. This system ensures the angle steel is securely positioned on the feeding conveyor for subsequent processing.
5. The workpiece is firmly clamped and conveyed by a CNC feeding carriage, guaranteeing precise positioning. The feeding carriage is driven by a servo motor, with feedback provided by a photoelectric encoder, operating under a closed-loop control system.
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 equipped with a high-speed hydraulic station featuring an integrated accumulator, and the hydraulic lines employ ferrule-type fittings, ensuring leak-free performance while enabling convenient replacement and maintenance. The main hydraulic valve blocks are sourced from the reputable Atos brand, providing a reliable and efficient hydraulic system.
7. The hydraulic station offers multiple cooling options, including water cooling, air cooling, or oil chilling. Clients may select the most suitable cooling method based on their specific operational requirements.
8. The control system is primarily comprised of a host computer, PLC, servo motors, external detection switches, and other essential components. Operators input the processing parameters, and the system automatically generates the corresponding machining program. It also supports reading DXF, NC, and other file formats generated by CAD software. The host computer features an intuitive human-machine interface, providing clear visualization and easy operation. It offers capabilities such as graphical workpiece display, comprehensive data storage, position data visualization, and fault alarm notifications.
These samples, representing standard specifications and typical processing conditions within the angle steel tower industry, allow users to directly assess the equipment’s processing quality, precision, and workmanship. They serve as a concrete reference for evaluating the machine’s performance and its appropriateness for specific production requirements, thereby supporting informed, data-driven decision-making for potential applications.
In the construction of ultra-high voltage (UHV) transmission lines, where towers must endure extreme weather conditions and substantial loads, this equipment serves a vital role in processing the angle steel components that form the primary framework of the towers. It efficiently carries out drilling and punching operations on the angle steel used for tower bodies, cross-arms, and other critical structural elements, ensuring accurate dimensions and secure connections that uphold the overall stability and structural integrity of the towers.
