Product Features:
1. The CNC angle iron punching machine is equipped with either two or three punching units, each designed to accommodate three distinct punch sizes. These punching units are precisely controlled by numerical control (NC) to adjust the punching positions accurately. The machine is capable of creating both round and oval holes. Its high-speed feeding and punching operations significantly improve production efficiency. For 50×50×4mm angle steel, the machine delivers an output capacity of 9-10 tons over an eight-hour shift.
2. The marking unit of the CNC angle punching machine is housed in a robust and rigid enclosure. The marking system comprises four cassette sets, which can be selected through programming, and the marking position can be freely adjusted. Additionally, the machine features a disc marking method with 10 rows, automatically selecting characters without the need for manual input, thereby greatly enhancing marking efficiency.
3. The CNC angle bar cutting machine is equipped with a single-blade shearing unit, known for its exceptional cutting force. Each cut is performed with zero material waste, and the resulting cutting surface is clean and smooth. The blade housing features an open-door design, allowing for rapid and safe blade replacement.
4. The horizontal material table efficiently transfers the angle bar to the rotating material rack, which is driven by a motor and reducer. This system ensures that the angle bar is securely positioned on the feeding conveyor for subsequent processing.
5. The workpiece is securely held and fed by a CNC feeding carriage, ensuring precise positioning accuracy. The feeding carriage is driven by a servo motor, with feedback from a photoelectric encoder, utilizing a closed-loop control system.
6. The CNC angle steel metal punching and marking machine operates through a hydraulic system that powers the punching, marking, and shearing functions. It is equipped with a high-speed hydraulic station featuring an accumulator, while the hydraulic lines are designed with ferrule-type connections, ensuring leak resistance and facilitating straightforward replacement and maintenance. The primary hydraulic valve blocks are sourced from the reputable Atos brand, guaranteeing a reliable and efficient hydraulic system.
7. The hydraulic station's cooling system offers various options, including water cooling, air cooling, or oil chilling. This flexibility allows customers to choose the most appropriate cooling method based on their specific operational needs.
8. The control system primarily comprises an upper computer, PLC, servo motor, external detection switches, and other essential components. The operator simply inputs the processing requirements, and the system automatically generates the corresponding processing program. It is also capable of reading DXF, NC, and other file formats generated by CAD software. The upper computer's human-machine interface is designed for ease of use, featuring an intuitive display and straightforward operation. It supports functions such as graphical workpiece display, extensive data storage, location data visualization, and fault alarm notifications.
These samples, which reflect standard specifications and typical processing conditions within the angle steel tower industry, enable users to directly evaluate the equipment's processing quality, accuracy, and craftsmanship. They provide a tangible reference for assessing the equipment's performance and its appropriateness for specific production requirements, thereby facilitating informed, data-driven decision-making for potential applications.
In the construction of ultra-high voltage (UHV) transmission lines, where towers are subjected to severe weather conditions and significant loads, this equipment is crucial for processing the angle steel components that form the primary structure of the towers. It effectively executes drilling and stamping operations on the angle steel used for tower bodies, cross-arms, and other key structural elements, ensuring precise dimensions and secure connections that maintain the overall stability and integrity of the towers.
