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.

Advantages of the Q91Y-1000 Scrap Steel Gantry Shear

1. The widened and lengthened V-shaped guide rail structure ensures a tight fit between the inner and outer slide rails, resulting in even force distribution and improved guiding of the upper blade holder, preventing blade slippage. The high-strength cast copper slide rails embedded at the four corners of the upper blade holder offer excellent wear resistance, low resistance, and a long service life. The steel triangular slide rails at the four corners of the gantry frame are inlaid with wear-resistant abrasive steel plates for durability. Furthermore, during operation, an automatic lubrication pump automatically lubricates the inner and outer slide rails.

2. The pressing mechanism adopts a concave and convex washboard structure to ensure the smooth operation and durability of the pressing mechanism.

3. The hydraulic oil cooling system adopts compressor cooling, which has good cooling effect, strong environmental adaptability and small footprint. The compressor can automatically start or stop according to the set oil temperature, and compared with water cooling, there is no waste and pollution of water resources, which is more in line with environmental protection requirements.

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 edge of the steel plate at the weld is beveled, and multi-layer and multi-pass welding is used, which has a good welding fusion effect and ensures reliable welding quality. The hydraulic pipeline weld adopts a special welding process, and flaw detection is carried out after welding to ensure that the pipeline is defect-free. The pipeline layout takes into account the fluid resistance factor, is neat and beautiful, and has a small pressure drop.

6. The entire door frame is first welded and machined up, down, left and right, and then closed and welded as a whole, which ensures the accuracy of the door frame and the smoothness of the slide during operation.

7. The equipment is equipped with a fully automatic control system. The core components use Siemens PLC and touch screen imported from Germany. The equipment working parameters are automatically controlled and the operation is simple and easy to learn.

8. The equipment working parameters and status can be displayed intuitively on the interface, which is convenient for equipment monitoring and maintenance and debugging. The entire operation process does not require unnecessary manual intervention. One-button start and stop can also realize independent start of single or multiple motors, truly realizing full-automatic control, which is simple and easy to learn for operators.
Parameters such as material pressing and tool holder lifting height can be set to avoid excessive empty shearing stroke. They can be adjusted according to the actual shearing material, thereby achieving the purpose of improving shearing efficiency and output and avoiding power waste.

9. The main frame structure has been subjected to stress analysis and actual verification, and the safety factor of the whole machine is high, ensuring that the whole machine is sturdy and durable.

10. All hydraulic pipelines are welded using high-pressure pipeline welding technology. The end faces on both sides of the weld are beveled, the base is welded with argon arc welding, and the surface is covered with double-protection welding. After a 24-hour high-pressure test, the surface is pickled to remove impurities on the inner wall to ensure that there are no impurities inside the hydraulic system and it can work smoothly for a long time.

11. The company has large-scale gantry milling and other machining equipment, which can carry out fine processing of the entire gantry to ensure the processing accuracy and quality of the entire equipment.
