Heavy Alligator Shear

Advantages of Heavy Alligator Shear

1. Precision selection of high-strength blades

The blade of crocodile shear adopts high-strength tempered steel (such as 42CrMo and other special alloys), and forms a dense and uniform martensitic structure through multiple heat treatment processes (quenching + tempering), and the hardness can reach HRC55-60. This material not only has excellent wear resistance, can cope with the continuous cutting of high hardness metals (such as stainless steel, titanium alloy), but also by optimizing the carbide distribution, effectively resist the edge crack and plastic deformation. The blade has a four-sided reversible structure, which can be rotated when one side is worn, significantly extending the service life and reducing the replacement frequency.

2. Seismic and stability of cast iron fuselage

The body of the fuselage is made of high-strength cast iron, whose graphite form has been optimized to combine the shock absorption characteristics of cast iron with the tensile strength of steel. This material can effectively disperse the impact force generated during cutting, reduce the vibration of the equipment, and ensure the stability of long-term operation. At the same time, the corrosion resistance of cast iron is better than that of ordinary steel, and it is especially suitable for metal recovery operations in wet or corrosive environments.

3. Material compatibility of hydraulic system

The hydraulic cylinder and pipeline are made of seamless steel pipe, the inner wall is honed, the surface roughness Ra≤0.4μm, to ensure the smooth flow of hydraulic oil and reliable sealing. The piston rod surface is plated with chromium (thickness ≥20μm) to form a dense oxide film, which effectively resists the scratching of metal debris and liquid corrosion, and extends the service life of hydraulic components.
