I. Overall Advantages of AEMK Gantry Shears

  • 1. High Hydraulic System Pressure: The AEMK gantry shear's hydraulic system operates at a shearing pressure of 28-29 MPa. While ensuring the hydraulic cylinder's designed thrust, it achieves 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, few defects, and high pressure resistance. The test pressure is 36.5 MPa, providing a high safety factor. The shearing cylinder can operate for extended periods at a working pressure of 29 MPa.

II. Detailed Introduction of Q91Y-800 Stepped Multi-blade Gantry Shear

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

  • 3. The hydraulic oil cooling system uses compressor cooling, which offers excellent cooling effect, 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.
  • Compressor 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 during waiting for materials. This achieves energy savings of 30% to 40% for the same output.

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

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. Operators are simple to learn.
  • Parameters such as material clamping and blade lifting height are settable to avoid excessive empty shear stroke. Adjustments can be made according to the actual material being sheared, thereby improving shearing efficiency and output while avoiding power waste.
