Alligator Shear Blades

What do Alligator Shear Blades Mean?

Alligator shear blades, also known as crocodile shear blades, are robust cutting tools used in alligator shears. These shears are characterized by a hinged jaw that opens and closes like the jaws of an alligator, hence the name. The blades, typically a stationary lower blade and a moving upper blade, are designed for cutting various types of metal scrap, bars, rods, and other materials. The term “alligator shear blades” specifically refers to the heavy-duty blades employed in these powerful shearing machines.

Uses and Applications of Alligator Shear Blades

Alligator shear blades are widely used in metal processing and recycling industries for reducing the size of various metallic materials. Key applications include:

• Scrap Metal Recycling: Cutting and sizing scrap metal such as automotive scrap, white goods, pipes, profiles, and mixed metal waste for easier handling, sorting, and further processing (e.g., shredding, baling).
• Non-Ferrous Metal Processing: Efficiently cutting copper, aluminum, brass, and other non-ferrous metals in various forms like wires, cables, extrusions, and castings.
• Construction and Demolition: Initial size reduction of metal debris from construction and demolition sites.
• Produzione: Cutting smaller pieces of metal stock like bars, rods, tubes, and profiles to specific lengths.
• Cable and Wire Recycling: Chopping cables and wires to liberate the metallic core from insulation.
• Radiator Recycling: Separating steel ends from aluminum components in radiators.
• Catalytic Converter Processing: Cutting open catalytic converters to access valuable internal metals.
• Deconstruction: Dismantling metallic structures or components.

Common Materials for Alligator Shear Blades

Alligator shear blades require high strength, toughness, and wear resistance to withstand the stresses of cutting various types of metal. Common materials include:

• Acciaio ad alto tenore di carbonio: Offers good initial sharpness and is suitable for cutting softer metals.
• Alloy Tool Steel (e.g., D2, A2, 6CrW2Si, H13): Provides a better balance of hardness, wear resistance, and toughness, making them suitable for a wider range of materials, including harder ferrous and non-ferrous metals. D2 is particularly known for its excellent wear resistance.
• Acciaio ad alta velocità (HSS): Offers superior wear resistance and the ability to retain hardness at higher operating temperatures, suitable for more demanding and continuous cutting operations.
• Leghe speciali: For specific applications, blades might be made from or inlaid with other tough and wear-resistant alloys to handle very hard or abrasive materials.
• Carburo di tungsteno: Used as inserts or sometimes for the entire blade for exceptional hardness and wear resistance when processing highly abrasive materials, significantly extending blade life.

Blades are often heat-treated to achieve optimal hardness (typically in the range of HRC 55-65) to maximize cutting performance and longevity. Many alligator shear blades are also 4-sided and reversible, allowing each cutting edge to be used before requiring sharpening or replacement, maximizing their lifespan and cost-effectiveness.

Common Scrap Shear Blade Shapes

Alligator shear blades typically have a relatively simple, robust design to withstand high cutting forces. Common shapes include:

• Straight Blades (Rectangular Cross-Section): The most common type, featuring a flat, straight cutting edge on both the upper and lower blades. These create a direct shearing action.
• Lame con bordo smussato: The cutting edges are angled to create a more efficient shearing action and can be single or double bevel depending on the application.
• Reversible Blades (4-Sided): Many alligator shear blades are designed to be rotated, offering four distinct cutting edges before needing regrinding or replacement. This maximizes blade life.
• Custom Profiles: Depending on the specific material being cut or the desired cut shape, blades with specialized profiles or notches can be manufactured.

The working principle involves the hinged upper blade being forced down by a hydraulic cylinder (or sometimes mechanical means) onto the stationary lower blade, with the material to be cut placed between them. The high force exerted by the shear cleanly severs the material. The length of the blades (ranging from 6 inches to 48 inches or more) and the cutting force of the shear determine the type and thickness of material that can be processed.
