Overall Advantages of AEMK Gantry Shears

1. High Hydraulic System Pressure: The AEMK gantry shear's hydraulic system has a shearing pressure of 28~29MPa. While ensuring the hydraulic cylinder's designed thrust is achieved, it boasts the fastest operating speed with the same motor power, offering advantages in speed and output compared to similar products.
2. Control System with a Fast Shearing Mode: When shearing sheet metal, a single button switch to fast shearing mode shortens the cylinder's idle time, increasing shearing speed and output while reducing energy consumption.
3. High Hydraulic Cylinder Pressure Resistance: The hydraulic cylinder barrel is forged, with thick walls and few defects, resulting in high pressure resistance. The test pressure is 36.5MPa, providing a high safety factor. The shearing cylinder can operate for extended periods under a working pressure of 29MPa.

Detailed Introduction to AEMK Hydraulic Gantry Shear

1. The wide V-shaped guide rail structure ensures a tight fit between the inner and outer slide rails, resulting in even force distribution. The inner high-wear-resistant cast copper slide rail is wear-resistant, has low resistance, and a long service life. The outer four corner triangular slide rails are inlaid with wear-resistant steel plates for durability. Furthermore, during operation, an automatic lubrication pump automatically lubricates both the inner and outer slide rails.

2. The material pressing mechanism employs a corrugated, washboard-like structure to ensure smooth operation and durability.

3. The hydraulic oil cooling system adopts a forced cooling method using a compressor, which provides excellent cooling performance, strong environmental adaptability, and a small footprint. The compressor can automatically start or stop according to the set oil temperature, and compared with water cooling, it avoids water waste and pollution, making it more environmentally friendly.

4. The power system adopts a servo motor and has been optimized in design, which improves mechanical efficiency and motor energy efficiency compared with conventional motors, and reduces the waste of power when waiting for materials, achieving energy savings of 30% to 40% under the premise of the same output.

5. Before welding, the edges of the steel plates at the weld seams are beveled, and multi-layer, multi-pass welding is employed, resulting in excellent fusion and reliable weld quality.

6. The entire gantry frame is first welded and machined separately on the top, bottom, left, and right sides, then assembled and welded as a whole. This ensures the gantry frame's precision and guarantees smooth operation of the sliding track.

7. The equipment is equipped with a fully automatic control system. Core components utilize imported German Siemens PLCs and touchscreens. Operating parameters are automatically controlled, and operation is simple and easy to learn.

8. Equipment operating parameters and status are displayed intuitively on the interface, facilitating equipment monitoring, maintenance, and debugging. The entire operation requires no manual intervention; one-button start and stop are available. Single or multiple motors can be started independently, achieving truly fully automatic control. The equipment is easy for operators to learn.
The equipment features a fast shearing mode, activated with a single button. This avoids excessive empty shearing strokes, improving shearing efficiency and output while preventing power waste.

9. The main frame structure has undergone stress analysis and practical verification, ensuring a high safety factor and robust durability.

10. All hydraulic lines utilize high-pressure welding technology. The weld ends are beveled, with argon arc welding for the root pass and MIG welding for the cap pass. Surface pickling removes impurities from the inner wall, ensuring a clean hydraulic system and stable long-term operation.
