Product Features:
1. High Positional Accuracy of Hole Making
The feeding device of this production line is driven by a servo motor via a rack-and-pinion transmission system. It is equipped with a rack-and-pinion detection mechanism and a position accuracy feedback encoder, forming a full closed-loop control system. The movement of the drilling power head along the two flanks of the angle steel is driven by a servo motor through a ball screw transmission, ensuring high positional accuracy of the holes on angle steel workpieces.
2. High Drilling Efficiency and Hole-Making Quality
The drilling unit is equipped with six sets of CNC drilling heads, with three sets allocated to each of the two flanges of the angle steel. Holes of the same diameter and with the same end distance on both flanges can be drilled simultaneously by the corresponding drilling heads on each side. The drilling spindle adopts a Taiwanese BT40 precision spindle (with internal cooling), and the drill bit utilizes a cemented carbide drill. The cutting speed of the drill bit reaches up to 200m/min (compared to 25-35m/min for conventional high-speed steel twist drills), enabling high-speed operation. The CNC drilling power head is driven by a servo motor for feeding, with the drill’s fast forward, working feed, and fast retraction controlled and automatically executed by the CNC system.
3. The cooling system exhibits exceptional effectiveness, preventing cutting fluids from leaking out of the machining cell. This maintains the cleanliness of the factory floor and eliminates the need for coolant removal treatments and containment measures.
4. The linear guideway employed for the moving guide of the drilling power head is a roller linear guideway, boasting excellent rigidity, high static and dynamic load capacities, and smooth operation. These attributes enhance both the quality of workpieces processed by the machine tool and the service life of tools.
These specimens encompass a range of common specifications and hole configurations of angle steel utilized in transmission line towers. They enable potential users or inspectors to visually validate the equipment’s performance, thereby offering a tangible and straightforward reference for evaluating its fitness for practical production requirements.
It is primarily designed for drilling and stamping large-size, high-strength angle steel used in transmission line towers, and is widely applied in various scenarios during the construction and maintenance of power transmission infrastructure.
In the construction of ultra-high voltage (UHV) transmission lines, where towers must endure extreme weather conditions and heavy loads, this equipment plays a vital role in processing the angle steel components that form the main framework of the towers. It efficiently handles the drilling and stamping tasks for the angle steel used in tower bodies, cross-arms, and other key structural parts, ensuring precise dimensions and strong connections to ensure the overall stability of the towers.
