Product Composition:
The equipment is primarily composed 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, forming a fully integrated automated angle steel processing line.
Product Features:
1. The machine combines mechanical, electrical, hydraulic, and pneumatic systems into a unified and efficiently coordinated processing platform, providing dependable automated manufacturing capabilities.
2. Independent drilling power heads are installed on both sides of the angle steel. Each drilling unit can optionally be equipped with a tool magazine accommodating up to four tools. This configuration allows all required holes on both legs of the angle steel to be machined within a single processing cycle, substantially enhancing production efficiency.
3. The drilling spindle is equipped with a high-precision BT40 spindle system, delivering excellent structural rigidity, dimensional accuracy, and consistent drilling performance.
4. The spindle assembly is compatible with both conventional twist drills and carbide drilling tools, providing versatile machining options for different material specifications and production conditions.
5. Hole spacing and machining locations can be freely programmed in accordance with specific production requirements, without restrictions on the number of punching rows, enabling flexible processing of complex hole arrangements.
6. The marking unit features a rigid enclosed-frame construction, providing excellent structural stability and marking precision during operation. The upper marking cassette accommodates four programmable character groups, while the marking pitch can be adjusted as required to satisfy different identification specifications.
7. The CNC control architecture integrates an industrial computer, servo drive system, PLC controller, external detection sensors, and other high-performance control components, ensuring precise machine operation and intelligent process supervision.
8. The CNC feeding carriage is servo motor driven, providing accurate positioning, high repeatability, and stable material transfer throughout the machining process.
9. Multiple data entry and communication methods are supported, including keyboard and mouse input, USB data transfer, and network connectivity. Machining information can be directly generated from professional 2D or 3D design software, streamlining programming and facilitating digital production integration.
10. Major electrical control devices, hydraulic components, and pneumatic elements are supplied by internationally established manufacturers, ensuring dependable operation, extended component service life, and consistent equipment performance.
11. Dedicated G-code conversion software is incorporated into the control system, enabling automatic conversion of CAD drawings into machine-readable machining programs. This function simplifies programming procedures and minimizes manual data entry.
12. The CNC operating interface provides graphical visualization of processed workpieces, allowing operators to conveniently verify machining layouts and relevant production information prior to processing.
13. An intelligent self-diagnostic function is integrated into the control system to automatically identify equipment abnormalities, display corresponding fault information, and assist operators in performing timely troubleshooting and maintenance.
These representative samples cover the standard angle steel specifications and typical processing requirements encountered in the transmission tower manufacturing industry. They enable users to directly assess the equipment’s machining quality, dimensional accuracy, processing consistency, and overall manufacturing standards.
In Ultra-High-Voltage (UHV) transmission line construction, where transmission towers are required to withstand severe weather conditions and considerable structural loads, this equipment provides an essential solution for manufacturing the angle steel components that constitute the primary tower framework. It efficiently performs drilling and punching operations on angle steel used for tower bodies, cross-arms, and other critical structural members. By maintaining accurate dimensions and ensuring secure, reliable connections, the system contributes significantly to the structural integrity, stability, and long-term reliability of UHV transmission towers.
