Product Features:
1. The complete production line consists of a transverse conveyor, turnover conveyor, infeed conveyor, CNC feeding carriage, two drilling assemblies, one marking assembly, an automatic unloading conveyor, a hydraulic power station, and an electrical cooling system. The equipment integrates advanced CNC technology with servo-controlled material feeding to achieve high processing efficiency, reliable operation, and consistent workpiece accuracy.
2. One drilling assembly is installed on each side of the machine. Each unit can accommodate three drills of different diameters. The entire drilling assembly is CNC-controlled and can move automatically to adjust hole spacing, ensuring precise hole positioning and consistent machining accuracy.
3. The spindle speed is continuously adjustable through a frequency inverter, while the feeding speed is regulated by variable-speed control valves. The transitions between rapid approach, machining feed, and rapid retraction are performed automatically, ensuring smooth operation and improved machining efficiency.
4. The drilling production line is equipped with one marking assembly, allowing marking intervals to be conveniently preset according to processing requirements. Marking operations, workpiece clamping, and drilling-unit feeding are hydraulically driven. Major components are imported to ensure dependable performance. An integrated circulating cooling system helps reduce tool temperature and extend drill service life.
5. Marking and drilling operations are completed automatically. Upon completion of machining, finished angle steel profiles are discharged through a pneumatic turnover mechanism, reducing manual handling, lowering workers' physical workload, and improving operational efficiency compared with conventional processing configurations.
6. The control system integrates an industrial host computer, servo motors, PLC, external monitoring switches, and other essential control components. Operators only need to enter the workpiece dimensions, after which the system automatically generates the corresponding machining program. Programs can also be stored, selected, displayed, and retrieved according to individual workpiece identification numbers, facilitating convenient production management.
7. The machining line is equipped with workpiece supporting and pressing mechanisms to accommodate angle steel profiles with considerable bending or deformation, ensuring stable positioning and reliable processing accuracy during machining.
These demonstration workpieces cover a variety of standard dimensions and typical hole configurations commonly used in angle steel transmission tower fabrication. They provide prospective customers and quality inspection personnel with practical reference samples for evaluating machining accuracy, processing performance, and finished-component quality. By examining the actual processed workpieces, users can determine whether the equipment satisfies the relevant manufacturing standards and production specifications for transmission tower applications.
In ultra-high-voltage (UHV) transmission line projects, transmission towers must withstand harsh weather conditions and considerable structural loads. This equipment is designed to manufacture the angle steel components that constitute the primary load-bearing framework of these structures. It performs high-precision drilling and punching operations on angle steel members used in tower bodies, cross-arms, and other essential structural assemblies, helping maintain accurate dimensions and dependable connection points. These machining capabilities contribute to enhanced structural integrity, improved operational stability, and long-term service reliability throughout the intended operating life of transmission towers.
