Product Features:
1. High Automation Level
The production line is equipped with an automatic loading device (comprising a transverse feeding channel and a rotating loading rack), an automatic unloading device, and an automatic feeding device. All holes and steel grade markings on the angle steel can be completed in a single pass through the production line; no manual intervention is needed during the processing process—this effectively reduces the labor intensity of operators.
2. Typing Unit Configuration & Function
The typing unit adopts a closed structure, featuring high strength and stable performance. The printing unit is equipped with a bed support (fixed on the machine base), a movable bed, and a hydraulic-driven press head character box. In accordance with instructions from the computer, printing operations are executed at the positions specified in the drawing. To expand the machine’s processing range, a manual adjustment mechanism is additionally integrated. By utilizing this mechanism, the downward position of the movable bed (i.e., the position of the character head) can be adjusted, enabling adaptation to the typing positions of angle steel with different specifications.
3. Drilling Spindle Configuration & Protection
The drilling spindle is equipped with a disc spring automatic tool clamping mechanism and a hydraulic cylinder for tool release, enabling convenient replacement of the tool shank. The front section of the spindle adopts a labyrinth seal protection structure and a waterproof design, and is fitted with an air curtain device—these configurations effectively prevent cutting fluid from penetrating into the interior of the spindle, ensuring the spindle’s stable operation and prolonged service life.
4. The hole-making process delivers high positional accuracy. The feeding device of this production line is driven by a servo motor and employs a gear-rack transmission system. It is further equipped with a gear-rack detection assembly and a position-sensing encoder for positional accuracy feedback, forming a full closed-loop control mechanism to ensure consistent feeding precision.
These specimens cover a range of common specifications and hole patterns of angle steel applied in transmission line towers. They enable potential users or inspectors to visually verify the operational performance of the equipment, thereby providing concrete and intuitive references for assessing whether the equipment meets the practical production requirements of transmission line tower manufacturing.
In the construction of ultra-high voltage (UHV) transmission lines—where towers are required to withstand extreme weather conditions and heavy loads—this equipment assumes a pivotal role in processing the angle steel components that constitute the main framework of the towers. It effectively fulfills the drilling and stamping tasks for angle steel applied in tower bodies, cross-arms, and other key structural parts, ensuring precise dimensional accuracy and robust connections to safeguard the overall stability of the towers.
