Automatic High-Accuracy Angle Steel Punching Line for Power Transmission Tower CNC Shearing Machine Construction

Automatic High-Accuracy Angle Steel Punching Line for Power Transmission Tower CNC Shearing Machine Construction About

Product Features

1. There are three or two sets of punching unit, which can be installed with three kinds of punches with different diameters. The three sets of punching dies are moved by numerical control to change the stadia. It can punch not only round holes but also oval holes. Its fast feeding and punching speeds improve production efficiency. For a 50*50*4mm angle steel, the output is 9-10 tons every eight hours.

2. The marking unit is closed with good rigidity. The marking unit has four sets of cassettes, which is chosen by programming and the typing stadia can be set at will. In addition, can choose the disc typing method. The disc typing has 10 rows and automatically selects characters without manual intervention, which greatly improves typing efficiency.

3. The cutting unit adopts single blade shearing which is popular with large shearing force. There is no waste in each cutting and the cutting surface is neat and smooth. The blade box has an open door design, which makes blade changing quick and safe.

4. The horizontal material table transfers the angle bar to the rotating material rack, which is driven by motor and reducer to place the angle bar steadily on the feeding conveyor.

5. The workpiece is held and fed by CNC feeding carriage with high positioning accuracy. CNC feeding carriage is driven by servo motor with photoelectric encoder feedback, closed-loop control.

6. The control system is mainly composed of upper computer, PLC, servo motor, external detection switch etc. The operator only needs to input processing requirements, the processing program can be automatically generated, it can also read DXF, NC and other processing files generated by lofting software. The man-machine interface display of the upper computer software is intuitive, and the operation is simple. lt can realize the function of work piece graph display, large amount of data storage, location data display, fault alarm and so on.

Efficient and Precise Angle Steel Processing

This punching line delivers seamless automation for angle steel used in power transmission towers. Its high punching and shearing forces streamline operations, while precise CNC positioning ensures minimal error. Industrial-grade oil and air cooling enable reliable performance for high-volume needs.


Advanced Automation and User-Friendly Operation

Operators benefit from a fully automatic workflow, requiring minimal intervention (only 1-2 personnel). The machine integrates industrial PLC control and a touchscreen HMI for programming, storing, and recalling up to 10,000 file presets. Ethernet and USB connectivity simplify data management.


Safety and Structural Robustness

Safety is central to the design, with full enclosure protection, emergency stops, and interlock sensors. The welded steel frame offers high rigidity, ensuring stable, vibration-free operations, even under continuous heavy workloads.
