What does Shear Blade Mean?

A shear blade, also known as a shearing blade or shear knife, is a crucial component of a shearing machine. It is a cutting tool designed to cut through various materials, most commonly metals (such as sheets, plates, bars, and coils), but also plastics, rubber, and composites, by applying a powerful shearing force. The term “shear blade” refers to the specific blade or set of blades used in the shearing process, where one blade typically moves past another fixed blade with a small clearance to sever the material.

Uses and Applications of Shear Blades

Shear blades are indispensable tools across a wide range of industries for cutting and processing materials. Key applications include:

• Metalworking and Fabrication: Cutting metal sheets and plates into specific sizes and shapes for manufacturing components in automotive, aerospace, construction, and appliance industries. This includes blanking, piercing, and trimming operations.
• Recycling Industry: Shearing scrap metal (like bars, rods, and plates) and other materials (such as compressed plastic bales and plastic film rolls) into smaller, manageable pieces for further processing. Alligator shears and gantry shears are specifically used for bulky scrap.
• Paper Industry: Guillotine cutters equipped with shear blades are used for cutting stacks of paper to precise dimensions in printing and packaging processes.
• Textile Industry: Cutting fabrics and textiles into patterns for garment manufacturing and other textile products.
• Packaging Industry: Cutting various packaging materials, including cardboard, plastics, and films, to size.
• Food Processing: Specialized shear blades can be used for cutting certain food products.
• Construction: Cutting metal elements like beams, girders, and slabs for bridge construction and other infrastructure projects.
• 조작: General cutting and shaping of various materials used in different manufacturing processes.
• Shipbuilding: Cutting and shaping metal sheets and plates for hulls, decks, and other ship parts.

Common Materials for Shear Blades

The material selection for shear blades is critical to ensure durability, wear resistance, and effective cutting performance, depending on the material being processed. Common materials include:

• 탄소강: Often used for cutting softer materials and for applications where cost is a primary concern. Grades like 65, 75, T8, and T10 are common.
• Low Alloy Tool Steel: Offers improved hardness and wear resistance compared to carbon steel. Common materials include 6CrW2Si, 9CrSi, and Cr12MoV, suitable for cutting stainless steel and medium-thick plates.
• High-Speed ​​Steel (HSS): Known for its ability to retain hardness at elevated temperatures, making it suitable for high-speed cutting of softer metals like aluminum and brass.
• 합금 공구강: Provides excellent toughness, wear resistance, and high-temperature resistance. Examples include H13 (4Cr5MoSiV1), LD (7Cr7Mo2V2Si9), and W6Mo5Cr4V2 (6542), used for hot-rolled steel billets and thick steel plates.
• 텅스텐 카바이드: Offers exceptional hardness and wear resistance, ideal for cutting hard metals, stainless steel, and abrasive materials. Often used as inserts in shear blades.
• Specialty Alloys: Certain applications may require blades made from specialized alloys to meet specific demands for hardness, toughness, or corrosion resistance.

The heat treatment process is also crucial in achieving the desired hardness and durability of the shear blades, typically ranging from HRC 57-62 depending on the material and application. Coatings like titanium can be used for aesthetic purposes but generally do not affect the cutting performance of the edge itself.

Common Shear Blade Shapes

가위날 come in various shapes and configurations depending on the type of shearing machine and the specific cutting operation. Some common shapes and types include:

• Straight Blades (Guillotine Blades): Long, straight blades used in guillotine shears for making straight cuts across the material. Often have multiple cutting edges that can be used.
• Rotary Blades (Circular Blades): Circular discs used for continuous cutting processes, often in roll-forming machines and rotary shearing equipment.
• Scissor Blades: Found in handheld shears for cutting lighter materials. They feature two opposing blades that pivot.
• Alligator Shear Blades: Hinged jaw blades used for cutting scrap metal, particularly smaller pieces like bars and rods.
• Gantry Shear Blades: Large blades used in gantry shears for shearing bulky scrap metal, including plates, bars, and even cars.
• Custom Shapes: Depending on specific industrial needs, shear blades can be manufactured in custom shapes and sizes.

The geometry of the shear blade, including the blade angle (rake angle or shear angle), the clearance between the upper and lower blades, and the edge configuration (straight, beveled, etc.), is critical for achieving clean and efficient cuts. The rake angle influences the cutting force required, while the blade clearance (typically around 7% of the material thickness) affects the quality of the cut edge. Insufficient clearance can lead to double cuts, while excessive clearance results in burred edges.
