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.
