I. 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.

II. Detailed Introduction of Q91Y-660 Stepped Multi-blade Gantry Shear

  • 1. The widened and lengthened V-shaped guide rail structure ensures tight fit between the inner and outer slide rails, uniform force distribution, and improved guidance of the upper blade holder, preventing blade skidding. The high-strength cast copper slide rails embedded at the four corners of the upper blade holder offer good wear resistance, low resistance, and long service life. The four corner steel triangular slides of the gantry are embedded with wear-resistant abrasive steel plates, ensuring durability. Furthermore, an automatic lubrication pump automatically lubricates the inner and outer slides during operation.

  • 2. The material pressing slide adopts a concave-convex washboard structure, ensuring smooth operation and long-lasting durability.
  • Material pressing mechanism
  • 3. The hydraulic oil cooling system uses a plate-fin radiator cooling method. Compared to water cooling, it occupies less space, requires no water resources, and does not generate wastewater, thus meeting environmental protection requirements. Moreover, our air-cooled radiator has a high safety factor and a heat dissipation capacity 2-2.5 times the rated heat dissipation capacity, resulting in excellent cooling performance.
  • Plate-fin radiator cooling system
  • 4. The power system uses a servo motor and has been optimized in design, improving mechanical efficiency and motor energy efficiency compared to conventional motors, and reducing wasted energy consumption during waiting for materials. This achieves energy savings of 30% to 40% under the same production capacity.

  • 5. Before welding, the edges of the steel plates at the weld seam are beveled, and multi-layer, multi-pass welding is used to ensure good fusion and reliable weld quality. The hydraulic pipeline welds employ a special welding process, followed by post-weld flaw detection to ensure the pipeline is defect-free. The pipeline layout takes fluid resistance into account, resulting in a neat, aesthetically pleasing design and minimal pressure drop.
