Feature and consist parts:

1. Loading Section:

The loading system primarily consists of a horizontal transport table and a rotating loading unit.
(1) The horizontal transport table is powered by sprockets and chains, ensuring the synchronization of three chains equipped with shift blocks. This mechanism ensures stable and low-noise operation during the transportation of the angle steel.
(2) The rotating loading unit is also driven by sprockets and chains, utilizing a long shaft and a custom coupling to achieve the synchronization of three rotating arms with reclaiming claws. This system's primary function is to transfer the angle steel from the trough on the material table to the feeding channel.

2. Feeding Section:

The feeding system is mainly composed of the feeding channel and the CNC trolley unit.
(1) The feeding channel consists of conveying rollers, brackets, transmission racks, and moving raceways.
(2) The feeding trolley includes the moving body, clamper, clamping cylinder, swing cylinder, servo motor, and encoder. During operation, the feeding trolley moves along guide rails on the plane and side of the drive rack in the feeding channel, with the clamper following the instructions provided by the computer.

3. Main Machine Components:

The primary system consists of the angle steel pressing unit, marking unit, punching unit, and shearing unit.
(1) The main function of the pressing unit is to apply pressure to the angle steel to prevent any deviation, thereby eliminating potential accuracy errors.
(2) The marking unit is designed to enable the exchange of positions within the four-character box. Based on the computer's instructions, it marks the angle steel at the specified locations according to the drawing. Additionally, a manual adjustment mechanism is incorporated to facilitate easy repositioning of the character head, ensuring compatibility with different angle steel specifications.
(3) The punching unit is equipped with three different specifications of punches on each side, with each punch featuring an air cylinder. The piston rod of each air cylinder is fitted with a cushion block, positioned between the punching rod and the pressing head of the hydraulic cylinder. Following the computer's instructions, the appropriate punch is automatically selected, which triggers the corresponding air cylinder to push the designated cushion block, thereby enabling the punch selection process.
(4) The shearing unit consists of a frame-type structure, a shearing cylinder, an upper blade mechanism, and a lower blade mechanism. The lower blade mechanism is adjustable to accommodate varying angle steel thicknesses, ensuring optimal cutting quality.

4. Discharging of Finished Products:
The system comprises a workpiece support roller and a rotating cylinder. By utilizing the control button on the control panel, the processed workpiece is rotated and positioned on either the left or right side.

5. Hydraulic Station:
The hydraulic station consists of an oil tank, high-pressure and low-pressure pump sets, a cooler, a main valve assembly, and other control valve assemblies. Its primary function is to supply power to the machine's hydraulic cylinders. The cooling system utilizes oil cooling technology to ensure optimal oil temperature regulation and cooling efficiency.

6. Electrical Control System:
The electrical control system consists of an electrical control cabinet, an operation box, and a mobile operation station.

(1) The host computer is equipped with control software, enabling the input of processing parameters for programming. The computer is also capable of recognizing programming files generated by CAD or CAM systems.

(2) The system utilizes a Mitsubishi PLC from Japan as the core control unit, integrated with a three-axis CNC module. This configuration forms a position control loop in conjunction with the X, A, and B axis servos, thereby ensuring the seamless integration of the PLC and CNC, significantly enhancing the system’s reliability.

(3) The drive system for the X, A, and B axes employs advanced AC brushless servo motors, guaranteeing rapid, precise positioning and requiring no maintenance.

(4) The control software continuously monitors the machine’s operation. In the event of a fault, the system will display a detailed diagnosis, including the cause of the issue and recommended corrective actions.

These samples, reflecting standard specifications and common processing conditions in the angle steel tower sector, enable users to directly evaluate the equipment’s quality, accuracy, and craftsmanship. They serve as a tangible benchmark for assessing the performance of the equipment and its adherence to defined production standards, thereby facilitating informed, data-driven decision-making for potential applications.

In the construction of ultra-high voltage (UHV) transmission lines, where towers are subjected to severe weather conditions and significant loads, this equipment is essential for processing the angle steel components that form the core structure of the towers. It reliably conducts drilling and stamping operations on the angle steel used for tower bodies, cross-arms, and other critical structural elements, ensuring precise dimensions and secure connections that maintain the overall stability and integrity of the towers.
