Hydraulic Alligator Shear Machine Process
The shearing action of an Alligator Hydraulic Shear Machine relies on the coordinated work of its hydraulic system and mechanical structure, transforming hydraulic energy into precise, powerful cutting motion to process hard materials. This process unfolds in a sequential, controlled manner to ensure efficient and safe material cutting.
1
Material Positioning and Clamping
Before shearing, the operator places the material to be cut on the machine's workbench, aligning it with the fixed shear blade. Some models are equipped with auxiliary positioning devices that hold the material in place, preventing it from shifting during cutting. This step is critical because stable material positioning ensures the shear blade acts on the correct area, avoiding uneven cutting or blade damage.
2
Hydraulic System Activation
The hydraulic system initiates the shearing drive. The hydraulic pump, powered by the prime mover, pressurizes hydraulic oil and sends it to the hydraulic cylinder through sealed pipelines. Under the pressure of the oil, the piston inside the cylinder moves linearly downward. This piston is connected to the machine's movable shear blade via a connecting rod, so the piston's downward motion drives the movable blade to descend toward the fixed blade.
3
Blade Cooperation and Cutting
The movable blade, moving with strong downward force, presses the material against the fixed blade. The edges of both blades are designed with sharp, angled profiles that concentrate force on the material's contact point. As the movable blade continues to descend, the combined pressure and sharp edge action breaks the material's internal structure—whether it is metal, scrap, or other hard materials—until the material is completely cut into the desired size.
4
Control and Regulation
During the process, a control valve regulates the flow of hydraulic oil, adjusting the descending speed of the movable blade. This prevents overly fast movement that could cause material deformation or blade impact, and also allows for slow, precise cutting when handling thicker materials. Once cutting is done, the control valve reverses the oil flow, pulling the piston and movable blade back to their original positions, ready for the next shearing cycle.
In summary, the machine's shearing action is a seamless combination of material positioning, hydraulic-driven blade movement, blade cooperation, and speed control—all working together to achieve reliable, efficient cutting.
