The hydraulic system is the powerhouse of a modern guillotine shearing machine, responsible for generating the immense force required to cut through thick metal plates while providing smooth, controlled motion for precise cutting results. A hydraulic guillotine shearing machine operates on the principle of hydraulic pressure to generate the force required to cut through metal sheets and profiles. The process begins with the hydraulic pump, which draws hydraulic fluid from a reservoir and pressurizes it, then directs this pressurized fluid to the hydraulic cylinders, which convert the hydraulic energy into mechanical force. As the cylinders extend, they push the upper blade downward towards the lower blade, applying immense pressure to the material and causing it to shear along the cutting line. Our guillotine shearing machines feature advanced hydraulic integrated valve blocks from Bosch-Rexroth, Germany, which feature a compact structure that reduces pipeline connections and improves system reliability and maintainability. The hydraulic system has the function of infinitely adjusting the stroke, allowing operators to optimize the cutting cycle for different material thicknesses. An accumulator or nitrogen cylinder system ensures smooth and rapid return travel, enhancing cycle times and productivity. The system pressure is controlled by electromagnetic proportional overflow valves, and the pressing pressure of the hold-down cylinder is independently controlled by pressure reducing valves to securely clamp the material before the cut. The maximum working pressure is set to 23 MPa before leaving the factory and can be adjusted as needed for different material types. For applications involving high-strength materials such as structural steel grades or stainless steel alloys, hydraulic guillotine shearing machines deliver consistent cutting force without the sudden impact characteristic of mechanical drives, which reduces blade wear and improves finished edge quality. The return stroke is reversed by the solenoid valve, completing the rapid cycle.
