Product Composition:
The machine consists mainly of a transverse conveying system, rotary loading mechanism, infeed conveyor, CNC feeding carriage, punching unit, marking unit, shearing unit, discharge conveyor, hydraulic system, electrical control system, pneumatic system, and other essential functional modules, forming a complete automated angle steel processing line.
Product Features:
1. The machine integrates mechanical, electrical, hydraulic, and pneumatic systems into a highly coordinated and efficient processing platform, providing reliable automated production capability.
2. Both sides of the angle steel are equipped with independent drilling power heads. Each drilling unit can be optionally configured with a tool magazine capable of storing up to four tools. This configuration enables simultaneous processing of all required holes on both sides of the angle steel within a single machining cycle, significantly improving production efficiency.
3. The drilling spindle adopts a high-precision BT40 spindle system, ensuring excellent rigidity, machining accuracy, and stable drilling performance.
4. The spindle system supports both conventional twist drills and carbide drilling tools, providing flexible machining capabilities for different material grades and production requirements.
5. The hole spacing and processing positions can be freely programmed according to production requirements, with no limitation on the number of punching rows, providing excellent flexibility for complex hole patterns.
6. The marking unit adopts a high-rigidity closed-frame structure, ensuring excellent stability and precision during operation. The upper marking cassette supports four programmable character groups, while the marking pitch can be adjusted freely to meet various identification requirements.
7. The CNC control system integrates an industrial computer, servo drive system, PLC controller, external detection sensors, and other high-performance control components, ensuring accurate operation and intelligent process management.
8. The CNC feeding carriage is driven by a servo motor, providing high positioning accuracy, excellent repeatability, and stable material feeding performance.
9. The system supports multiple data input methods, including keyboard and mouse operation, USB data transfer, and network communication. Machining data can be directly generated from professional 2D or 3D design software, improving programming efficiency and digital production integration.
10. The main electrical control components, hydraulic components, and pneumatic elements are sourced from internationally recognized suppliers, ensuring reliable operation, long service life, and stable equipment performance.
11. The system is equipped with specialized G-code conversion software, which can automatically transform CAD drawings into machine-executable machining programs, simplifying programming procedures and reducing manual input requirements.
12. The CNC interface provides graphical visualization of processed components, allowing operators to conveniently review machining layouts and production information before processing.
13. An intelligent self-diagnostic function is integrated into the system to automatically detect equipment abnormalities, display fault information, and assist operators in rapid troubleshooting and maintenance.
These samples, which reflect the standard specifications and processing requirements within the angle steel tower industry, enable users to directly evaluate the equipment’s processing quality, precision, and craftsmanship standards.
In the construction of ultra-high voltage (UHV) transmission lines, where towers are subjected to extreme weather conditions and substantial loads, this equipment is crucial for processing the angle steel components that form the primary structure of the towers. It consistently executes drilling and stamping operations on the angle steel used in tower bodies, cross-arms, and other vital structural components. This ensures precise dimensional accuracy and robust, secure connections, contributing to the overall stability and reliability of the towers.
