Transmission Tower Manufacturing Single Blade Shearing Angle Line Telecom Tower Production

Transmission Tower Manufacturing Single Blade Shearing Angle Line Telecom Tower Production

Product Introduction:

The machine is an automated, specialized production line designed for marking, punching (circular and oval holes), and shearing angle steel. It is primarily utilized in industries such as the angle steel tower sector, power fittings, structural storage facilities, and steel structure construction, among others.

Main Component:

This machine is principally comprised of a transverse conveyor, a rotating loading system, an infeed conveyor, a CNC infeed carriage, a punching unit, a marking unit, a cutting unit, an unloading conveyor, as well as hydraulic, electrical, and pneumatic systems, among others.

Feature and consist parts:

1. Loading Section:

This section is primarily comprised of a horizontal transport table and a rotating loading unit.
(1) The horizontal transport table operates via sprockets and chains, ensuring the synchronization of three chains with shift blocks. This design ensures stable and low-noise conveying of angle steel during the process.
(2) The rotating loading unit is driven by sprockets and chains, utilizing a long shaft and a custom coupling to synchronize three rotating arms with reclaiming claws. This system transports the angle steel from the material table's trough to the feeding channel for further processing.

2. Feeding Section:

This section mainly consists of the feeding channel and the CNC trolley unit.
(1) The feeding channel includes conveying rollers, support brackets, transmission racks, and moving raceways.
(2) The feeding trolley comprises a moving body, a clamper, a clamping cylinder, a swing cylinder, a servo motor, and an encoder. During operation, the feeding trolley is guided by rails on both the plane and side of the drive rack within the feeding channel, moving the clamper according to instructions from the control system.

3. Main Components of the Machine:

This section is composed of the angle steel pressing unit, marking unit, punching unit, and shearing unit.
(1) The primary function of the pressing unit is to secure the angle steel in place, preventing any deviation that could lead to inaccuracies during the process.
(2) The marking unit is capable of exchanging the positions of four character boxes. Based on the computer's instructions, it marks the angle steel at the specified locations according to the drawing. A manual adjustment mechanism is included to facilitate easy repositioning of the character heads, allowing for adaptability to different specifications of angle steel.
(3) The punching unit is designed with three different punch specifications on each side. Each punch is equipped with an air cylinder, and a cushioning block is positioned on the piston rod of the air cylinder, situated between the punching rod and the hydraulic cylinder's pressing head. Based on computer instructions, the appropriate punch is automatically selected by activating the corresponding air cylinder, which then pushes the cushion block to choose the correct punch.
(4) The shearing unit consists of a frame structure, a shearing cylinder, an upper knife mechanism, and a lower knife mechanism. The lower knife mechanism can be adjusted to control the gap according to the thickness of the angle steel, ensuring high-quality cuts.

4. Unloading Section for Finished Products:

This section is made up of workpiece support rollers and a turning cylinder. Using the control buttons on the control station, the processed workpieces are rotated and placed on either the left or right side as required.

5. Hydraulic Station:

The hydraulic station comprises an oil tank, high and low-pressure pump units, a cooler, a main valve assembly, and various other control valve groups. Its purpose is to supply hydraulic power to each oil cylinder of the machine. The cooling system employs oil cooling technology to ensure effective cooling and maintain the oil's quality.

6. Electrical Control System:

The electrical control system consists of an electrical operation cabinet, an operation box, and a trolley operating station.
(1) The host computer is equipped with control software that allows input of processing parameters for programming. The computer can also recognize program files generated from CAD or CAM systems.
(2) The system uses a Mitsubishi Electric PLC from Japan as the core control unit, integrated with a three-axis CNC module. This forms a position control loop with the X, A, and B axis servos, enhancing the integration of the PLC and CNC to significantly improve system reliability.
(3) The X, A, and B axis drives are powered by advanced AC brushless servo motors, ensuring high-speed, precise positioning and requiring no maintenance.
(4) The control software continuously monitors the machine’s operation. In the event of a fault, the screen displays a detailed description of the issue along with suggested troubleshooting steps.

These samples, which reflect standard specifications and typical processing conditions in the angle steel tower industry, enable users to directly evaluate the quality, accuracy, and craftsmanship of the equipment. They serve as a tangible benchmark for assessing the machine’s performance and its adherence to specific production standards, thereby facilitating informed, data-driven decisions for potential applications.

In the construction of ultra-high voltage (UHV) transmission lines—where towers must withstand harsh weather conditions and heavy loads—this equipment is essential for processing the angle steel components that form the backbone of the towers. It reliably executes drilling and stamping operations on the angle steel used in tower bodies, cross-arms, and other key structural elements, ensuring precise dimensions and secure connections that maintain the overall stability of the towers.
