Product Composition:
The equipment mainly consists of a transverse material 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 assemblies, together forming a highly integrated and fully automated angle steel processing line.
Product Features:
1. The machine integrates mechanical, electrical, hydraulic, and pneumatic technologies into a unified and precisely coordinated processing system, providing reliable automated manufacturing performance and efficient production capabilities.
2. Independent drilling power heads are arranged on both sides of the angle steel. Each drilling unit can be optionally fitted with a tool magazine capable of holding up to four tools. This configuration enables all required holes on both legs of the angle steel to be completed within a single machining cycle, significantly improving overall production efficiency.
3. The drilling spindle incorporates a high-precision BT40 spindle system, offering excellent mechanical rigidity, high dimensional accuracy, and stable, repeatable drilling performance.
4. The spindle assembly supports both standard twist drills and carbide drilling tools, providing flexible tooling options to accommodate different material specifications and machining requirements.
5. Hole spacing and machining positions can be freely programmed according to specific production requirements. The system is not limited by the number of punching rows, allowing flexible processing of complex hole patterns and customized hole arrangements.
6. The marking unit adopts a rigid enclosed-frame structure, ensuring excellent structural stability and high marking accuracy throughout operation. The upper marking cassette is equipped with four programmable character groups, while the marking pitch can be adjusted according to specific identification and production requirements.
7. The CNC control architecture integrates an industrial computer, servo drive system, PLC controller, external detection sensors, and other high-performance control components, providing precise machine control, intelligent process monitoring, and reliable automated operation.
8. The CNC feeding carriage is driven by a servo motor, delivering accurate positioning, high repeatability, and stable workpiece transportation throughout the entire machining process.
9. The system supports multiple data input and communication methods, including keyboard and mouse operation, USB data transfer, and network connectivity. Machining data can be generated directly from professional 2D or 3D design software, simplifying programming procedures and facilitating seamless integration with digital production workflows.
10. Major electrical control components, hydraulic units, and pneumatic components are sourced from internationally recognized manufacturers, providing reliable operation, extended component service life, and consistent overall equipment performance.
11. Dedicated G-code conversion software is integrated into the control system, enabling automatic conversion of CAD drawings into machine-readable machining programs. This capability simplifies programming operations while reducing manual data input and minimizing the possibility of programming errors.
12. The CNC operating interface incorporates graphical visualization of the workpiece being processed, enabling operators to conveniently review machining layouts, workpiece information, and relevant production data before commencing the machining operation.
13. An intelligent self-diagnostic function is incorporated into the control system to automatically detect equipment abnormalities, provide corresponding fault information, and assist operators in carrying out timely troubleshooting, servicing, and maintenance.
These representative samples encompass the standard angle steel specifications and typical machining requirements commonly encountered in the transmission tower manufacturing industry. They allow users to directly evaluate the equipment's machining quality, dimensional accuracy, process consistency, and overall manufacturing performance.
In Ultra-High-Voltage (UHV) transmission line construction, transmission towers must withstand demanding weather conditions and substantial structural loads. This equipment provides an effective manufacturing solution for processing the angle steel components that form the primary framework of these towers. It efficiently performs drilling and punching operations on angle steel used for tower bodies, cross-arms, and other critical structural members. By maintaining precise dimensions and facilitating secure and dependable structural connections, the system makes an important contribution to the structural integrity, stability, safety, and long-term service reliability of UHV transmission towers.
