Product Structure Characteristics:
1. High degree of automation. This production line is equipped with automatic feeding devices (horizontal feeding channels and rotating feeding racks), automatic unloading devices, and automatic feeding devices. All holes and steel seal marks on the angle steel can be processed through this production line at once without manual assistance, greatly reducing the labor intensity of workers.
2. The typing unit adopts a closed body, with high strength and stable body. The printing unit consists of a bed frame fixed on the machine base, a moving bed frame, a hydraulic power pressure head letterbox, and other components. According to the instructions of the computer, print at the required position on the drawing. In order to meet the processing range of the machine, a manual adjustment mechanism has been added, which can change the downward position of the moving body (i.e. the position of the letter head) to adapt to the typing position of different specifications of angle steel.
3. The positional accuracy of hole making is high. The feeding device of this production line is driven by a servo motor, with gear and rack transmission, and equipped with a detection gear and a detection encoder for position accuracy feedback, forming a fully closed-loop control; The movement of the drilling power head in the direction of the two wings of the angle steel is driven by a servo motor and transmitted by a ball screw, thereby ensuring high precision in the position of the hole on the angle steel workpiece.
4. High drilling efficiency and drilling quality. The drilling unit is equipped with six sets of CNC drilling power heads, with three sets on each wing of the angle steel. The upper ends of the two wings of the angle steel have holes of the same diameter and distance, and the corresponding drilling power heads on both sides can be drilled simultaneously.
5. The drilling spindle is from Taiwan BT40 precision spindle (internal cooling), and the drill bit is made of cemented carbide. The cutting speed of the drill bit can reach 200m/min (25-35m/min for high-speed steel Fried Dough Twists drills), and the feeding speed is fast. The servo motor drives the feed of the CNC drilling power head, and the fast forward, work forward, and rewind of the drill bit are controlled by the CNC system and automatically completed. The retreat position of the drill bit can be set in the upper computer, reducing the idle stroke and further improving production efficiency. The aperture tolerance of the hole is less than 0.1mm, the smoothness Ra of the hole is less than 6.3 μ m, and the machining quality of the hole is relatively high.
6. It is recommended to use a hard alloy drill bit that can be converted into a blade drill bit. The blade has four cutting blades, which are replaceable and do not require grinding, resulting in low production costs. The cooling of the drill bit adopts the most advanced MQL (Minimum Quantities of Lubricant) cooling system internationally. The MQL system can mix compressed air with a very small amount of lubricant (cutting oil) and vaporize it before spraying it into the machining area for effective cooling and lubrication. The consumption of cutting oil is extremely low, about 5-50ml/h.
7. The cooling effect is good, and it will not cause cutting fluid to flow out of the machining unit, thus keeping the factory floor clean and eliminating the need for cleaning, processing, and containing these cooling fluids.
8. The linear guide for the movement of the drilling power head adopts a roller linear guide, which has good rigidity, high static and dynamic load capacity, and smooth operation, thus improving the quality of the machined workpiece and the service life of the tool.
9. The main solenoid valves of the hydraulic system are made of foreign products, and the hydraulic pipelines are connected by sleeve type pipelines. The cooling of the hydraulic system is done by air cooling.
10. The upper computer is easy to operate. It can display the coordinates and dimensions of the workpiece graphics and hole positions for easy inspection, and can also accept workpiece processing programs generated by layout software. Adopting upper computer management greatly facilitates the storage and retrieval of programs.
These test samples encompass a broad spectrum of standard specifications and hole configurations pertinent to the angle steel utilized in the manufacturing of transmission line towers. They enable potential clients or inspectors to visually evaluate the equipment's operational performance, offering clear and tangible references to assess whether the equipment aligns with the practical production standards required for transmission line tower fabrication.
In ultra-high voltage (UHV) transmission line projects—where transmission towers must withstand harsh weather conditions and heavy loads—this equipment plays a vital role in processing the angle steel components that constitute the primary load-bearing structures of the towers. It efficiently performs drilling and stamping operations on the angle steel used in tower bodies, cross-arms, and other critical structural components, ensuring precise dimensional accuracy and robust connection integrity. As a result, it guarantees the long-term structural stability and dependability of the transmission towers throughout their entire operational lifespan.
